Abstract
To compare the oncological survival outcome between extended resections (ER) and segmental resection (SR) for non-metastatic splenic flexure tumors. A total of 10,063 splenic flexure colon cancers patients who underwent ER (n = 5546) or SR (n = 4517) from 2010 to 2018 were included from the Surveillance, Epidemiology, and End Results (SEER)-registered database. Additionally, we included 135 patients from our center who underwent ER (n = 54) or SR (n = 81) between 2011 and 2021. Survival rates were compared between groups. To reduce the inherent bias of retrospective studies, propensity score matching (PSM) analysis was performed. In the SEER database, patients in the ER group exhibited higher pT stage, pN stage, larger tumor size, and elevated rates of CEA level, perineural invasion, and tumor deposits compared to those in the SR group (each P < 0.05). The 5-year cancer-specific survival (CSS) rate was slightly lower in the ER group than in the SR group (79.2% vs. 81.6%, P = 0.002), while the 5-year overall survival (OS) rates were comparable between the two groups (66.2% vs. 66.9%, P = 0.513). After performing PSM, both the 5-year CSS and 5-year OS rates were comparable between the ER and SR groups (5-year CSS: 84.9% vs. 83.0%, P = 0.577; 5-year OS: 70.6% vs. 66.0%, P = 0.415). These findings were consistent in the subgroup analysis that included only patients with stage III disease or tumor size ≥ 7 cm. Furthermore, although the number of harvested lymph nodes was higher in the ER group compared to the SR group (14.4 vs. 12.7, P < 0.001), the number of invaded lymph nodes remained similar between the two groups (0.5 vs. 0.5, P = 0.90). Similarly, our center's data revealed comparable 3-year OS and 3-year disease-free survival (DFS) rates between the two groups. ER have no significant oncological benefits over SR in the treatment of non-metastatic splenic flexure colon cancer, even for locally advanced cases.

Cureus 2024; 16:e63821. [PMID: 39100032 PMCID: PMC11297727 DOI: 10.7759/cureus.63821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 07/04/2024] [Indexed: 08/06/2024] Open
Abstract
Backgrounds Colorectal surgeons worldwide have differing opinions on the best way to handle rare cases of splenic flexure colon cancers (SFCs). Although the majority of reviews indicate no significant variation in oncological outcomes among the three different procedure types used to treat SFCs, surgeons still exhibit diversity in their practices. This study determined the treatment preferences of colorectal surgeons in Saudi Arabia. Methods A descriptive cross-sectional study evaluated the management of colorectal surgeons in handling SFC cases. We utilized a validated questionnaire developed by Manceau et al., consisting of 14 questions. Emails and phone numbers of members of the Saudi Society of Colorectal Surgery (SSCRS) were gathered. Google Forms surveys were administered from October 1-30, 2023. Results A response rate of 66% (58/88) was obtained among questioned colorectal surgeons. Their responses revealed that there was no consensus regarding the preferred procedure to treat SFCs. The most common treatment reported was segmental colectomy (SC) 21/58 (36.2%), followed by subtotal colectomy (STC) (19/58, 32.8%) and left hemicolectomy (LHC) (18/58, 31%). There was a strong consensus of 96% (56/58) of the respondents in favor of using stapler anastomosis rather than hand sewing. The frequency of performing SC, STC, and LHC in France was 70%, 13%, and 17%, respectively, compared to 36.2%, 32.8%, and 31% in Saudi Arabia, with a p-value of 0.001. The surgeons' preferred approaches to managing SFCs utilizing laparoscopic, open, or hand-aided in France versus Saudi Arabia were 63%, 31%, and 11%, respectively, compared to 84.5%, 8.6%, and 6.9%, with a p-value of 0.001. Conclusion A significant disparity exists regarding the treatment of SFCs between colorectal surgeons in France and Saudi Arabia. Furthermore, there is a lack of consensus among colorectal surgeons in Saudi Arabia regarding the surgical management of SFCs. Hence, it is imperative for the SCRSS to assemble a panel of experts to reach a consensus for the most appropriate and effective treatment of SFCs.

Front Oncol 2024; 14:1244693. [PMID: 38686198 PMCID: PMC11057231 DOI: 10.3389/fonc.2024.1244693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 03/18/2024] [Indexed: 05/02/2024] Open
Abstract
Background Colorectal cancer is among the most common cancers in the world, and splenic flexure colon cancer accounts for about 2-5% of them. There is still no consensus on the surgical treatment of splenic flexure colon cancer (SFCC), and the extent of surgical resection and lymph node dissection for SFCC is still controversial. Aim To compare the postoperative and long-term oncologic outcomes of extended right colectomy (ERC), segmental colectomy (SC) and left colectomy (LC) for SFCC. Method Up to March 2024, retrospective and prospective studies of ERC, SC, and LC for SFCC were searched through databases. Pooled weighted/standardized mean difference (WMD/SMD), odds ratio (OR) and hazard ratio (HR) with 95% confidence interval (CI) were calculated using a fixed effects model or random effects model, and meta-analysis was performed using Stata. Results This meta-analysis includes 5,918 patients from 13 studies with more lymph node harvest (OR:6.29; 95%Cl: 3.66-8.91; Z=4.69, P=0), more operation time (WMD: 22.53; 95%Cl: 18.75-26.31; Z=11.68, P=0), more blood loss (WMD:58.44; 95%Cl: 20.20-96.68; Z=2.99, P=0.003), longer hospital stay (WMD:1.74; 95%Cl: 0.20-3.29; Z=2.21, P=0.03), longer time to return to regular diet (WMD:3.17; 95%Cl: 2.05-4.30; Z=5.53, P=0), longer first flatus time (WMD:1.66; 95%Cl: 0.96-2.37; Z=4.61, P=0) in ERC versus SC. More lymph node harvest (WMD: 3.52; 95% Cl: 1.59-5.44; Z=3.58, P=0) in ERC versus LC and LC versus SC (WMD: 1.97; 95% CI: 0.53-3.41; Z=2.68, P=0.007), respectively. There is no significant difference between anastomotic leakage, postoperative ileus, total postoperative complication, severe postoperative complication, wound infection, reoperations, R0 resection, postoperative mortality, 5-year overall survival (OS), 5-year disease-free survival (DFS) in three group of patients. In LC versus SC and ERC versus LC, there is no difference between operation time, blood loss, hospital stay, return to regular diet, and first flatus. Conclusion In the included studies, SC and LC may be more advantageous, with fewer postoperative complications and faster recovery. ERC harvests more lymph nodes, but there is no significant difference in long-term OS and DFS between the three surgical approaches. Given that the included studies were retrospective, more randomized controlled trials are needed to validate this conclusion.

SF-CORNER (splenic flexure colorectal cancer): an international survey of operative approaches and outcomes for cancers of the splenic flexure. Colorectal Dis 2024; 26:660-668. [PMID: 38345176 DOI: 10.1111/codi.16895] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 11/12/2023] [Accepted: 12/10/2023] [Indexed: 05/02/2024]
Abstract
AIM The optimum surgical approach to splenic flexure cancers (SFCs) remains uncertain. The aim of this survey was to explore the opinions of an international surgical community on the management and outcomes of SFC. METHOD A questionnaire was constructed comprising five sections (information about respondents; definition and prognosis of SFC; operative approach; approach in specific scenarios; outcomes) and circulated through an international dissemination committee and social media. RESULTS The survey received 576 responses over 4 weeks across 50 countries. There was no consensus regarding the definition of the splenic flexure, whilst the proportion of respondents who did and did not think that patients with SFC had a worse outcome was equal. The overall preferred operative approach was left hemicolectomy [203 (35.2%)], followed by segmental resection [167 (29%)], extended right hemicolectomy [126 (21.9%)] and subtotal colectomy [7 (12%)]. The stated pedicles for ligation varied between resection types and also within the same resection. One hundred and sixty-six (28.8%) respondents thought a segmental resection was associated with the worst survival and 190 (33%) thought it was associated with the best quality of life. CONCLUSION This survey confirms a lack of consensus across all aspects SFC treatment. The differing approaches described are likely to represent different beliefs around the variable anatomy of this region and the associated lymphatic drainage. Future studies are required to address such inconsistencies and identify the optimum surgical strategy, whilst also incorporating quality-of-life metrics and patient-reported outcomes. A one-size-fits-all approach is probably not appropriate with SFC, and a more bespoke approach is required.

Abstract
ABSTRACT This review article examines the evidence-based management of colorectal cancers, focusing on topics characterized by ongoing debates and evolving evidence. To contribute to the scientific discourse, we intentionally exclude subjects with established guidelines, concentrating instead on areas where the current understanding is dynamic. Our analysis encompasses a thorough exploration of critical themes, including the evidence surrounding complete mesocolic excision and D3 lymphadenectomy in colon cancers. Additionally, we delve into the evolving landscape of perioperative chemotherapy in both colon and rectal cancers, considering its nuanced role in the context of contemporary treatment strategies. Advancements in surgical techniques are a pivotal aspect of our discussion, with an emphasis on the utilization of minimally invasive approaches such as laparoscopy and robotic surgery in both colon and rectal cancers, including advanced rectal cases. Moving beyond conventional radical procedures, we scrutinize the feasibility and implications of endoscopic resections for small tumors, explore the paradigm of organ preservation in locally advanced rectal cancers, and assess the utility of total neoadjuvant therapy in the current treatment landscape. Our final segment reviews pivotal trials that have significantly influenced the management of colorectal liver and peritoneal metastasis.

Surgical management strategies for colorectal malignancies of the splenic flexure - A systematic review and network meta-analysis. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:107087. [PMID: 37793302 DOI: 10.1016/j.ejso.2023.107087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 08/27/2023] [Accepted: 09/16/2023] [Indexed: 10/06/2023]
Abstract
BACKGROUND Extended right hemicolectomy (ERHC) or left hemicolectomy (LHC) are accepted as the standard-of-care for colonic tumours of the splenic flexure. Lymphatic drainage at this site is poorly defined and subject to significant heterogeneity. Nevertheless, emerging evidence demonstrates the potential oncological safety of segmental splenic flexure colectomy (SFC). AIM To perform a systematic review and network meta-analysis (NMA) to compare outcomes following ERHC, LHC and SFC for splenic flexure tumours (SFTs). METHODS A systematic review was performed as per PRISMA guidelines. NMA was performed using R Shiny and Netmeta packages. RESULTS A total of 13 studies, involving 6176 patients (ERHC n = 785; LHC n = 1527; SFC n = 3864) were included in the NMA. There was no difference in overall survival (OS) (SFC vs LHC Hazard Ratio [HR] 1.0, 95% Credible Interval [CrI] 0.76,1.34; SFC vs ERHC HR 1.18, 95% CrI 0.85,1.58) between the groups. SFC had a shorter operation time (Mean 176.37 min; Mean Difference [MD] SFC vs LHC 20.34 min 95% CrI 10.9, 29.97; SFC vs ERHC MD 22.19 95% CrI 11.09, 33.29) but also had a lower average lymph node yield (LNY) compared with ERHC (MD 7.15, 95% CrI 5.71, 8.60). ERHC had a significantly higher incidence of post-operative ileus (Odds Ratio [OR] 3.47, 95% CrI 1.11, 10.84). There was also no difference observed for minimally invasive approaches, anastomotic leak rate, perioperative mortality, reoperation rates or length of stay. CONCLUSIONS While SFC may allow for reduced operative duration and improved bowel function postoperatively. SFC, LHC, ERHC are all acceptable approaches for curative resection of cancers of the splenic flexure, with no difference in OS observed. Thus, surgeon preference and candidate-specific factors will likely determine the management of SFTs.

Abstract
BACKGROUND Surgical management of splenic flexure carcinoma remains controversial. OBJECTIVE This study aimed to establish an expert international consensus on splenic flexure carcinoma management. DESIGN A 3-round online-based Delphi study was conducted between September 2020 and April 2021. SETTING The first round included 18 experts from 12 different countries. For the second and third rounds, each expert in the first round was asked to invite 2 more colorectal surgeons (n = 47). Out of 47 invited experts, 89% (n = 42) participated in the second and third rounds of the consensus. INTERVENTIONS A total of 35 questions were created and sent via the online questionnaire tool. MAIN OUTCOME MEASURES Levels of recommendation based on voting concordance were graded as follows: more than 75% agreement was defined as strong, between 50% and 75% as moderate, and below 50% as weak. RESULTS There was moderate consensus on the definition of splenic flexure (55%) as 10 cm from either side where the distal transverse colon turns into the proximal descending colon. Also, experts recommended an abdominopelvic CT scan plus intraoperative exploration (moderate consensus, 72%) for tumor localization and cancer registry. Segmental colectomy was the preferred technique for the management of splenic flexure carcinoma in the elective setting (72%). Moderate consensus was achieved on the technique of complete mesocolic excision and central vascular ligation principles for splenic flexure carcinoma (74%). Only strong consensus was achieved on the surgical approach for minimally invasive surgery (88%). LIMITATIONS Subjective decisions are based on individual expert clinical experience and not evidence based. CONCLUSIONS This is the first internationally conducted Delphi consensus study regarding splenic flexure carcinoma. The definition of splenic flexure remains ambiguous. To more effectively compare oncologic outcomes among different cancer registries, guidelines need to be developed to standardize each domain and avoid arbitrary definitions.

ESTANDARIZACIN DE LA DEFINICIN Y MANEJO QUIRRGICO DEL CARCINOMA DE NGULO ESPLNICO ESTABLECIDO POR UN CONSENSO INTERNACIONAL DE EXPERTOS UTILIZANDO LA TCNICA DELPHI ESPACIO PARA MEJORAR ANTECEDENTES:El tratamiento quirúrgico del cáncer de ángulo esplénico sigue siendo controvertido.OBJETIVO:Establecer un consenso internacional de expertos sobre el manejo del cáncer del ángulo esplénico.DISEÑO:Se condujo un estudio Delphi en línea de 3 rondas entre septiembre de 2020 y febrero de 2021.ESCENARIO:La primera ronda incluyó a 18 expertos de 12 países distintos. Para la segunda y tercera rondas, a cada experto de la primera ronda se le pidió que invitara a 2 cirujanos colorrectales más de su región (n = 47). De los 47 expertos invitados, el 89% (n = 42) participó en la segunda y tercera ronda del consenso.INTERVENCIONES:Se crearon y enviaron un total de 35 preguntas a través de la herramienta de cuestionario en línea.PRINCIPALES MEDIDAS DE RESULTADO:Los niveles de recomendación basados en la concordancia de votos fueron jerarquizados de la siguiente manera: más del 75% de acuerdo se definió como fuerte, entre 50 y 75% como moderado y por debajo del 50% como débil.RESULTADOS:Hubo un consenso moderado sobre la definición de ángulo esplénico (55%) como 10 cm desde cualquier lado donde el colon transverso distal se convierte en el colon descendente proximal. Así también, los expertos recomendaron la tomografía computarizada abdominopélvica más la exploración intraoperatoria (consenso moderado, 72%) para la localización del tumor y el registro del ángulo esplénico. La colectomía segmentaria fue la técnica preferida para el tratamiento del cáncer de ángulo esplénico en el caso de ser electivo (72%). Se logró un consenso moderado sobre la técnica de escisión completa del mesocolon y los principios de ligadura vascular a nivel central para el cáncer de ángulo esplénico (74%). Solo se logró un fuerte consenso sobre el abordaje quirúrgico para la cirugía mínimamente invasiva (88%).LIMITACIONES:Decisiones subjetivas basadas en la experiencia clínica de expertos individuales y no basadas en evidencia.CONCLUSIONES:Este es el primer estudio internacional de consenso Delphi realizado sobre el cáncer de ángulo esplénico. Si bien encontramos un consenso moderado sobre las modalidades de diagnóstico preoperatorio y el manejo quirúrgico, la definición de ángulo esplénico sigue siendo ambigua. Para comparar de manera más efectiva los resultados oncológicos entre diferentes registros de cáncer, se deben desarrollar pautas para estandarizar cada dominio y evitar definiciones arbitrarias.

Abstract
BACKGROUND Surgical intervention is the recommended line for the management of colon cancer. The aim of this study was to evaluate the impact of different surgical techniques (laparoscopic, open, extended right, and left colectomy) on clinical outcomes such as mortality, postoperative complications, operation and hospitalization time, and oncological factors. METHODS A total of 15 studies have been included in the current study. The outcomes of these studies were analyzed using a random-effect model and it was used to calculate the mean difference with 95% confidence intervals to quantify the impact of open, laparoscopic, extended right, and left colectomy. Inclusion criteria included studies in which subjects undergo splenic flexure colon cancer surgery with 2 comparable different surgical techniques. RESULTS Laparoscopic splenic flexure colon cancer surgery showed a significant beneficial impact on the length of hospital stay (P < .001), the volume of blood loss during surgery (P < .001), postoperative complications (P < .001), and time to an oral diet (P < .001). On the other hand, there was no significance regarding anastomotic leakage, infection of the surgical site, and operation time. Regarding the comparison between extended right colectomy (ERC) and lift colectomy (LC), analysis findings showed a significant (P = .001) higher efficacy of ERC in harvested number of lymph nodes compared with LC. On the other hand, there was no significant difference for the rest of the parameters. The neoadjuvant therapy as an influencing factor on postoperative outcome showed a beneficial impact regarding the overall survival rate. CONCLUSION Laparoscopic splenic flexure colon cancer surgery showed a significant beneficial impact compared with open surgery as proved by clinical outcomes. On the other hand, ERC and LC resulted in similar findings except for harvested lymph nodes, results were in favor of ERC.

Abstract
OBJECTIVE To investigate the effect of primary tumor resection (PTR) on the prognosis of patients with unresectable colon cancer liver metastasis (UCCLM) at seven colonic subsites using the Surveillance, Epidemiology, and End Results (SEER) database. METHODS Propensity score matching (PSM) was performed to balance selection bias using all available variables that could be of potential relevance. After matching, the groups were redefined in a 1:1 ratio using the nearest method. Cancer-specific survival (CSS) was compared among the patients of PTR and non-PTR groups. Cox regression models were used to identify the prognostic factors for CSS. RESULTS CSS was significantly different between all groups. Cox regression analysis showed that PTR was an independent prognostic factor for all groups. After PSM, PTR significantly prolonged CSS for all groups. Subgroup analysis showed that PTR did not improve the prognosis of N2 stage patients in the cecum, ascending colon, and descending colon groups; T1 + T2 stage patients in the hepatic flexure group; and patients with a tumor size ≤5 cm in the splenic flexure group. Segmental colectomy could prolong CSS of patients in the cecum, ascending colon, transverse colon, splenic flexure, and sigmoid colon groups, while extended colectomy could prolong CSS of patients in the hepatic flexure and descending colon groups. CONCLUSION At different colonic subsites, UCCLM patients had different CSS. PTR could improve their prognosis, however, N stage, T stage, and tumor size are important reference indicators. In addition to patients in the hepatic flexure and descending colon groups, we suggested that patients in other groups should choose segmental colectomy.

Inferior mesenteric vein preserving lymphadenectomy in high left segmental colectomy for splenic flexure melanoma: A case report. Int J Surg Case Rep 2023; 104:107956. [PMID: 36878180 PMCID: PMC10009196 DOI: 10.1016/j.ijscr.2023.107956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 02/23/2023] [Accepted: 02/27/2023] [Indexed: 03/06/2023] Open
Abstract
INTRODUCTION AND IMPORTANCE Surgical resection is the mainstay for management of splenic flexure cancers, with the aim of achieving adequate lymphadenectomy. Left-sided bowel resections often require ligation of the inferior mesenteric vein (IMV) for mesocolic dissection or lymphadenectomy which can result in congestive colitis on the anal side of the anastomosis secondary to poor venous outflow. Preserving the IMV may mitigate this risk but is technically difficult and can compromise oncological resection. This case report is a rare example of high left segmental resection of the splenic flexure with preservation of the IMV in a patient with splenic flexure melanoma. CASE PRESENTATION A non-obstructing lesion was discovered in a 73-year-old male who underwent colonoscopy following a positive faecal occult blood test. Biopsy of the lesion confirmed a melanoma. This patient had a history of cutaneous melanoma which was excised 20 years prior. A laparoscopic high left segmental colectomy was performed, and metastatic melanoma was identified in 3 of 12 regional lymph nodes. The patient recovered with no complications. CLINICAL DISCUSSION This patient underwent high left segmental colectomy to achieve oncological clearance while resecting minimal bowel and preserving bowel function. The IMV was spared in this surgery to prevent venous congestion. Reports of colitis following left sided colectomy have been described, whereby colitis is thought to result from a mismatch in arterial perfusion and venous drainage following IMV resection. CONCLUSION This case highlights the potential role of preservation of the inferior mesenteric vein in a rare case of splenic flexure melanoma.

Best surgical approach for splenic flexure colon cancers: Extended versus segmental resection? Am J Surg 2023; 225:454-459. [PMID: 36404169 DOI: 10.1016/j.amjsurg.2022.11.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Revised: 10/30/2022] [Accepted: 11/10/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND The optimal surgical treatment approach for splenic flexure colon cancers remains controversial regarding the type of resection. METHODS We hypothesized that both extended and segmental resections have similar surgical and oncologic outcomes. A retrospective review of prospectively collected database was performed on all patients who had colectomy for splenic flexure colon cancer between 1996 and 2018. RESULTS Of 142 patients, 119 underwent extended resection; therefore, this group was compared with the group which underwent segmental resection (n = 23). The groups were similar in age, sex, ASA scores, operative times, estimated blood loss, hospital length of stay, and postoperative complication rates (p > 0.05). Median follow-up was 9.58 years (IQR:5.46-16.48). Multivariable regression models demonstrated no significant association between resection approach and disease-free survival (HR 1.63 [95%CI:0.91-2.92]), as well as overall survival (HR 1.80 [95%CI:0.97; 3.36]). CONCLUSION In the treatment of splenic flexure colon cancer, segmental colon resections have similar oncologic outcomes when compared to extended colectomies.

Abstract
BACKGROUND There is currently no consensus on surgical management of splenic flexure adenocarcinoma (SFA). METHODS Patients undergoing surgical resection for SFA between 1993 and 2015 were identified. Postoperative outcomes were compared between patients who underwent segmental (SR) vs. anatomical resection (AR). RESULTS One-hundred and thirteen patients underwent SR and 89 underwent AR. More patients in the SR group had open resections, but there were otherwise no differences in demographics or surgical characteristics between the two groups. There were no differences in overall (p = 0.29) or recurrence-free(p = 0.37) survival. On multivariable analysis, increased age (HR 1.04, 1.01-1.07, p = 0.005), higher American Society of Anesthesiology classification (HR 3.1, 1.7-5.71, p < 0.001), and higher tumor stage (HR 8.84, 3.76-20.82, p < 0.001) were predictive of mortality. CONCLUSIONS Short and long-term outcomes after SR and AR for SFA are not different, making SR a viable option for SFA surgical management.

Abstract
Liver resection is still the most effective treatment of primary liver malignancies, including hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA), and of metastatic disease, such as colorectal liver metastases. The type of liver resection (anatomic versus non anatomic resection) depends on different features, mainly on the type of malignancy (primary liver neoplasm versus metastatic lesion), size of tumor, its relation with blood and biliary vessels, and the volume of future liver remnant (FLT). Imaging plays a critical role in postoperative assessment, offering the possibility to recognize normal postoperative findings and potential complications. Ultrasonography (US) is the first-line diagnostic tool to use in post-surgical phase. However, computed tomography (CT), due to its comprehensive assessment, allows for a more accurate evaluation and more normal findings than the possible postoperative complications. Magnetic resonance imaging (MRI) with cholangiopancreatography (MRCP) and/or hepatospecific contrast agents remains the best tool for bile duct injuries diagnosis and for ischemic cholangitis evaluation. Consequently, radiologists should be familiar with the surgical approaches for a better comprehension of normal postoperative findings and of postoperative complications.

Re-interpreting mesenteric vascular anatomy on 3D virtual and/or physical models, part II: anatomy of relevance to surgeons operating splenic flexure cancer. Surg Endosc 2022; 36:9136-9145. [PMID: 35773607 PMCID: PMC9652173 DOI: 10.1007/s00464-022-09394-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 06/06/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND The splenic flexure is irrigated from two vascular areas, both from the middle colic and the left colic artery. The challenge for the surgeon is to connect these two vascular areas in an oncological safe procedure. MATERIALS AND METHODS The vascular anatomy, manually 3D reconstructed from 32 preoperative high-resolution CT datasets using Osirix MD, Mimics Medical and 3-matic Medical Datasets, were exported as STL-files, video clips, stills and supplemented with 3D printed models. RESULTS Our first major finding was the difference in level between the middle colic and the inferior mesenteric artery origins. We have named this relationship a mesenteric inter-arterial stair. The middle colic artery origin could be found cranial (median 3.38 cm) or caudal (median 0.58 cm) to the inferior mesenteric artery. The lateral distance between the two origins was 2.63 cm (median), and the straight distance 4.23 cm (median). The second finding was the different trajectories and confluence pattern of the inferior mesenteric vein. This vein ended in the superior mesenteric/jejunal vein (21 patients) or in the splenic vein (11 patients). The inferior mesenteric vein confluence could be infrapancreatic (17 patients), infrapancreatic with retropancreatic arch (7 patients) or retropancreatic (8 patients). Lastly, the accessory middle colic artery was present in ten patients presenting another pathway for lymphatic dissemination. CONCLUSION The IMV trajectory when accessible, is the solution to the mesenteric inter-arterial stair. The surgeon could safely follow the IMV to its confluence. When the IMV trajectory is not accessible, the surgeon could follow the caudal border of the pancreas.

Abstract
Purpose: To assess the qualitative relationship between liquid biopsy and conventional tissue biopsy. As a secondary target, we evaluated the relationship between the liquid biopsy results and the T stage, N stage, M stage, and compared to grading. Methods: The Local Ethics Committee of the “Università degli Studi della Campania Luigi Vanvitelli”, with the internal resolution number 24997/2020 of 12.11.2020, approved this spontaneous prospective study. According to the approved protocol, patients with lung cancer who underwent Fine-Needle Aspiration Cytology (FNAC), CT-guided biopsy, and liquid biopsy were enrolled. A Yates chi-square test was employed to analyze differences in percentage values of categorical variables. A p-value < 0.05 was considered statistically significant. Data analysis was performed using the Matlab Statistic Toolbox (The MathWorks, Inc., Natick, MA, USA). Results: When a genetic mutation is present on the pathological examination, this was also detected on the liquid biopsy. ROS1 and PDL1 mutations were found in 2/29 patients, while EGFR Exon 21 was identified in a single patient. At liquid biopsy, 26 mutations were identified in the analyzed samples. The mutations with the highest prevalence rate in the study populations were: ALK (Ile1461Val), found in 28/29 patients (96.6%), EML4 (Lys398Arg), identified in 16/29 (55.2%) patients, ALK (Asp1529Glu), found in 14/29 (48.3%) patients, EGFR (Arg521Lys), found in 12/29 (41.4%) patients, ROS (Lys2228Gln), identified in 11/29 (37.9%) patients, ROS (Arg167Gln) and ROS (Ser2229Cys), identified in 10/29 (34.5%) patients, ALK (Lys1491Arg) and PIK3CA (Ile391Met), identified in 8/29 (27.6%) patients, ROS (Thr145Pro), identified in 6/29 (20.7%) patients, and ROS (Ser1109Leu), identified in 4/29 (13.8%) patients. No statistically significant differences can be observed in the mutation rate between the adenocarcinoma population and the squamous carcinoma population (p > 0.05, Yates chi-square test). Conclusions: We showed that, when a genetic mutation was detected in pathological examination, this was always detected by liquid biopsy, demonstrating a very high concordance rate of genomic testing between tissues and their corresponding mutations obtained by liquid biopsy, without cases of false-negative results. In addition, in our study, liquid biopsy highlighted 26 mutations, with the prevalence of ALK mutation in 96.6% of patients, supporting the idea that this approach could be an effective tool in cases with insufficient tumor tissue specimens or in cases where tissue specimens are not obtainable.

Clinical impact of inferior mesenteric vein preservation during left hemicolectomy with low ligation of the inferior mesenteric artery for distal transverse and descending colon cancers: A comparative study based on computed tomography. Front Oncol 2022; 12:986516. [PMID: 36081545 PMCID: PMC9445569 DOI: 10.3389/fonc.2022.986516] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 08/04/2022] [Indexed: 11/13/2022] Open
Abstract
Purpose Presence of a long remnant sigmoid colon after left hemicolectomy with inferior mesenteric vein (IMV) ligation for distal transverse and descending colon cancers may be a risk factor for venous ischemia. This study aimed to evaluate the clinical impact of IMV preservation in patients who underwent left hemicolectomy with inferior mesenteric artery (IMA) preservation. Methods We included 155 patients who underwent left hemicolectomy with IMA preservation for distal transverse and descending colon cancers from 2003 to 2020. Technical success of IMV preservation was determined by assessing pre- and post-operative patency of the IMV on computed tomography (CT) by an abdominal radiologist. Intestinal complications comprising ulceration, stricture, venous engorgement, and colitis in remnant colon were compared between the IMV preservation and ligation groups. Results IMV was preserved in 22 (14.2%) and ligated in 133 (85.8%) patients. Surgical time, postoperative recovery outcomes, and number of harvested lymph nodes were similar in both groups. The technical success of IMV preservation was 81.8%. Intestinal complications were less common in the preservation group than in the IMV ligation group (4.5% vs. 23.3%, P=0.048). The complications in the IMV ligation group were anastomotic ulcer (n=2), anastomotic stricture (n=4), venous engorgement of the remnant distal colon (n=4), and colitis in the distal colon (n=21). Conclusions IMV preservation may be beneficial after left hemicolectomy with IMA preservation for distal transverse and descending colon cancers. We suggest that IMV preservation might be considered when long remnant sigmoid colon is expected during left hemicolectomy with low ligation of IMA.

Abstract
Objective: The aim of this manuscript is to give an overview of structured reporting in radiological settings. Materials and Method: This article is a narrative review on structured reporting in radiological settings. Particularly, limitations and future perspectives are analyzed. RESULTS: The radiological report is a communication tool for the referring physician and the patients. It was conceived as a free text report (FTR) to allow radiologists to have their own individuality in the description of the radiological findings. However, this form could suffer from content, style, and presentation discrepancies, with a probability of transferring incorrect radiological data. Quality, datafication/quantification, and accessibility represent the three main goals in moving from FTRs to structured reports (SRs). In fact, the quality is related to standardization, which aims to improve communication and clarification. Moreover, a “structured” checklist, which allows all the fundamental items for a particular radiological study to be reported and permits the connection of the radiological data with clinical features, allowing a personalized medicine. With regard to accessibility, since radiological reports can be considered a source of research data, SR allows data mining to obtain new biomarkers and to help the development of new application domains, especially in the field of radiomics. Conclusions: Structured reporting could eliminate radiologist individuality, allowing a standardized approach.

Abstract
Melanoma patient remains a challenging for the radiologist, due to the difficulty related to the management of a patient more often in an advanced stage of the disease. It is necessary to determine a stratification of risk, optimizing the means, with diagnostic tools that should be optimized in relation to the type of patient, and improving knowledge. Staging and risk assessment procedures are determined by disease presentation at diagnosis. Melanoma staging is a critical tool to assist clinical decision-making and prognostic assessment. It is used for clinical trial design, eligibility, stratification, and analysis. The current standard for regional lymph nodes staging is represented by the sentinel lymph node excision biopsy procedure. For staging of distant metastases, PET-CT has the highest sensitivity and diagnostic odds ratio. Similar trend is observed during melanoma surveillance. The advent of immunotherapy, which has improved patient outcome, however, has determined new issues for radiologists, partly due to atypical response patterns, partly due to adverse reactions that must be identified as soon as possible for the correct management of the patient. The main objectives of the new ir-criteria are to standardize the assessment between different trials. However, these ir-criteria do not take into account all cases of atypical response patterns, as hyperprogression or dissociated responses. None of these criteria has actually been uniformly adopted in routine. The immune-related adverse events (irAEs) can involve various organs from head to toe. It is crucial for radiologists to know the imaging appearances of this condition, to exclude recurrent or progressive disease and for pneumonitis, since it could be potentially life-threatening toxicity, resulting in pneumonitis-related deaths in early phase trials, to allow a proper patient management.

Abstract
Desmoid tumors (DTs), also known as desmoid fibromatosis or aggressive fibromatosis, are rare, locally invasive, non-metastatic soft tissue tumors. Although histological results represent the gold standard diagnosis, imaging represents the fundamental tool for the diagnosis of these tumors. Although histological analysis represents the gold standard for diagnosis, imaging represents the fundamental tool for the diagnosis of these tumors. DTs represent a challenge for the radiologist, being able to mimic different pathological conditions. A proper diagnosis is required to establish an adequate therapeutic approach. Multimodality imaging, including ultrasound (US), computed tomography (CT) and Magnetic Resonance Imaging (MRI), should be preferred. Different imaging techniques can also guide minimally invasive treatments and monitor their effectiveness. The purpose of this review is to describe the state-of-the-art multidisciplinary imaging of DTs; and its role in patient management.

Abstract
Background The aim of this study was to compare the short- and long-term outcomes of splenic flexure colectomy (SFC), left hemicolectomy (LHC) and extended left hemicolectomy (ELHC) for splenic flexure colon cancer. Methods Between January 2011 and December 2018, 117 patients with splenic flexure cancer were enrolled in the study. We retrospectively compared the postoperative, pathological and long-term outcomes of patients with splenic flexure cancer. Results Of the 117 patients, 73 (62.4%) underwent SFC, 22 (18.8%) underwent LHC, and 22 (18.8%) underwent ELHC. No statistically significant differences were found among the groups regarding postoperative complications, pathological data or recurrence. No metastatic lymph nodes at the root of the inferior mesenteric artery (IMA) were observed; lymph node metastasis appeared at the root of the middle colic artery (MCA), but in a low proportion of cases (4.4%). Looking at long-term prognosis, no differences were observed among the three groups regarding both 5-year overall survival (94.0% vs 90.2% vs 94.1%) and disease-free survival (88.2% vs 90.2% vs 83.0%). Conclusion Our retrospective review suggests that splenic flexure colectomy in minimally invasive surgery is a safe and effective treatment option for splenic flexure colon cancer. The rate of metastatic lymph nodes at the root of the central artery and gastroepiploic arcade node was relatively low.

Abstract
To evaluate the clinical efficacy and safety of the rCCK96-104PE38 targeted drug in patients with colon cancer in general surgery, data of 80 patients with colon cancer who were admitted to the hospital from April 2019 to July 2021 were selected and randomly divided into the treatment group and the control group, with 40 cases in each group. Patients in the treatment group were treated with the rCCK96-104PE38 targeted drug, and those in the control group were treated with oxaliplatin. The treatment efficiency and incidence of adverse reactions were compared between the two groups. The inverse cholecystokinin (CCK96-104) was fused with pseudomonas aeruginosa exotoxin (PE38 toxin) through the gene amplification technique to construct a prokaryotic expression vector. Then, the rCCK96-104PE38 was purified by Ni-nitrilotriacetate (Ni-NTA) affinity chromatography, and the antitumor activity of rCCK96-104PE38 was verified. The results showed that the amplified rCCK96-104PE38 sequence was correct and the pET-28a prokaryotic expression system was adopted to successfully achieve active expression. The purified recombinant protein could induce the apoptosis of colon cancer cells in vitro and inhibit tumor growth in vivo. The total effective rate in the treatment group (80%, 32/40) was higher than that in the control group (60%, 24/40) (P < 0.05). To sum up, the recombinant toxin rCCK96-104PE38 could not only specifically adsorb the colon cancer cells with high expression of CCK2R but also effectively inhibit tumor tissue growth and proliferation. Besides, the rCCK96-104PE38 protein had a good anticancer effect that helped effectively reduce the incidence of adverse reactions in patients, which was worthy of promoting.

Abstract
PURPOSE The purpose of this study is to evaluate the Radiomics and Machine Learning Analysis based on MRI in the assessment of Liver Mucinous Colorectal Metastases.Query METHODS: The cohort of patients included a training set (121 cases) and an external validation set (30 cases) with colorectal liver metastases with pathological proof and MRI study enrolled in this approved study retrospectively. About 851 radiomics features were extracted as median values by means of the PyRadiomics tool on volume on interest segmented manually by two expert radiologists. Univariate analysis, linear regression modelling and pattern recognition methods were used as statistical and classification procedures. RESULTS The best results at univariate analysis were reached by the wavelet_LLH_glcm_JointEntropy extracted by T2W SPACE sequence with accuracy of 92%. Linear regression model increased the performance obtained respect to the univariate analysis. The best results were obtained by a linear regression model of 15 significant features extracted by the T2W SPACE sequence with accuracy of 94%, a sensitivity of 92% and a specificity of 95%. The best classifier among the tested pattern recognition approaches was k-nearest neighbours (KNN); however, KNN achieved lower precision than the best linear regression model. CONCLUSIONS Radiomics metrics allow the mucinous subtype lesion characterization, in order to obtain a more personalized approach. We demonstrated that the best performance was obtained by T2-W extracted textural metrics.

Abstract
In the recent years, the number of liver resections has seen an impressive growth. Usually, hepatic resections remain the treatment of various liver diseases, such as malignant tumors, benign tumors, hydatid disease, and abscesses. Despite technical advancements and tremendous experience in the field of liver resection of specialized centers, there are moderately high rates of postoperative morbidity and mortality, especially in high-risk and older patient populations. Although ultrasonography is usually the first-line imaging examination for postoperative complications, Computed Tomography (CT) is the imaging tool of choice in emergency settings due to its capability to assess the whole body in a few seconds and detect all possible complications. Magnetic resonance cholangiopancreatography (MRCP) is the imaging modality of choice for delineating early postoperative bile duct injuries and ischemic cholangitis that may arise in the late postoperative phase. Moreover, both MDCT and MRCP can precisely detect tumor recurrence. Consequently, radiologists should have knowledge of these surgical procedures for better comprehension of postoperative changes and recognition of the radiological features of various postoperative complications.

Complications Risk Assessment and Imaging Findings of Thermal Ablation Treatment in Liver Cancers: What the Radiologist Should Expect. J Clin Med 2022; 11:jcm11102766. [PMID: 35628893 PMCID: PMC9147303 DOI: 10.3390/jcm11102766] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 05/10/2022] [Accepted: 05/12/2022] [Indexed: 02/04/2023] Open
Abstract
One of the major fields of application of ablation treatment is liver tumors. With respect to HCC, ablation treatments are considered as upfront treatments in patients with early-stage disease, while in colorectal liver metastases (CLM), they can be employed as an upfront treatment or in association with surgical resection. The main prognostic feature of ablation is the tumor size, since the goal of the treatment is the necrosis of all viable tumor tissue with an adequate tumor-free margin. Radiofrequency ablation (RFA) and microwave ablation (MWA) are the most employed ablation techniques. Ablation therapies in HCC and liver metastases have presented a challenge to radiologists, who need to assess response to determine complication-related treatment. Complications, defined as any unexpected variation from a procedural course, and adverse events, defined as any actual or potential injury related to the treatment, could occur either during the procedure or afterwards. To date, RFA and MWA have shown no statistically significant differences in mortality rates or major or minor complications. To reduce the rate of major complications, patient selection and risk assessment are essential. To determine the right cost-benefit ratio for the ablation method to be used, it is necessary to identify patients at high risk of infections, coagulation disorders and previous abdominal surgery interventions. Based on risk assessment, during the procedure as part of surveillance, the radiologists should pay attention to several complications, such as vascular, biliary, mechanical and infectious. Multiphase CT is an imaging tool chosen in emergency settings. The radiologist should report technical success, treatment efficacy, and complications. The complications should be assessed according to well-defined classification systems, and these complications should be categorized consistently according to severity and time of occurrence.

Magnetic Resonance Features of Liver Mucinous Colorectal Metastases: What the Radiologist Should Know. J Clin Med 2022; 11:jcm11082221. [PMID: 35456314 PMCID: PMC9027866 DOI: 10.3390/jcm11082221] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2022] [Revised: 04/01/2022] [Accepted: 04/12/2022] [Indexed: 02/06/2023] Open
Abstract
Purpose: The aim of this study is to assess MRI features of mucinous liver metastases compared to non-mucinous metastases and hepatic hemangioma. Methods: A radiological archive was assessed from January 2017 to June 2021 to select patients subjected to liver resection for CRCLM and MRI in the staging phase. We selected 20 patients with hepatic hemangioma (study group B). We evaluated (a) the maximum diameter of the lesions, in millimeters, on T1-W flash 2D in phase and out phase, on axial HASTE T2-W and on portal phase axial VIBE T1 W; and (b) the signal intensity (SI) in T1-W sequences, in T2-W sequences, Diffusion-Weighted Imaging (DWI) sequences and apparent diffusion coefficient (ADC) maps so as to observe (c) the presence and the type of contrast enhancement during the contrast study. The chi-square test was employed to analyze differences in percentage values of the categorical variable, while the non-parametric Kruskal−Wallis test was used to test for statistically significant differences between the median values of the continuous variables. A p-value < 0.05 was considered statistically significant. Results: The final study population included 52 patients (33 men and 19 women) with 63 years of median age (range 37−82 years) and 157 metastases. In 35 patients, we found 118 non-mucinous type metastases (control group), and in 17 patients, we found 39 mucinous type metastases (study group A). During follow-up, recurrence occurred in 12 patients, and three exhibited mucinous types among them. In the study group, all lesions (100%) showed hypointense SI on T1-W, very high SI (similar to hepatic hemangioma) in T2-W with restricted diffusion and iso-hypointense signals in the ADC map. During the contrast study, the main significant feature is the peripheral progressive enhancement.

Abstract
The transverse colon has anatomical peculiarities in the middle position between the foregut and the midgut. Because the transverse colon harbors a flexure at both ends, mobilization of the transverse colon can be especially challenging compared with other colons. Although transverse colon cancer is relatively uncommon, an optimal surgical management for transverse colon cancer must be established. In transverse colon cancer, proximity to the pancreas and variation in arterial and venous anatomy make radical resection more difficult. Dissection of lymph nodes around the middle colic vessels is a critical step in transverse colon cancer resection. The proximity of the middle colic vessels to the superior mesenteric vessels contributes to the complexity of this step, making it challenging for less-trained surgeons. For these reasons, patients with transverse colon cancer were not included in most landmark studies that compared laparoscopic surgery with open surgery. More radical operations, such as subtotal colectomy or extended right or left hemicolectomy, can be performed for transverse colon cancer to secure an adequate lymphadenectomy. Such cancers have also been treated with limited segmental colectomies, such as right, transverse, or left colectomy. Currently, there is still a lack of standardized definitions and procedures. Therefore, it is time to discuss and establish optimal surgical treatments for transverse colon cancer.

Abstract
Abstract
Background There are many surgical approaches which described extent of resection of the colon for adequate surgical management of splenic flexure cancer, but up till now there is no established surgical procedure, this is because the presence of double lymphatic drainage of the mesenteric vessels. Segmental resection of the colon for the management of splenic flexure cancer was a recently accepted surgical procedure.
Objective In the present study, we aimed to compare three surgical management techniques to clarify the best management approach of Egyptian patients with splenic flexure cancer regarding operative, clinical, and oncological outcomes: segmental resection, and extended left or right hemicolectomy,.
Materials and Methods In the present study, we included 90 patients with splenic flexure cancer. Cases were divided into 3 groups. Each group included 30 patients in order to compare three surgical techniques: segmental resection, extended left hemicolectomy, and extended right hemicolectomy.
Results We have found no statistically significant differences between the three included groups regarding operative findings, postoperative complications, local recurrence, distant recurrence, disease progression, recurrence-free survival rate, progression-free survival rate, and overall survival rate. The operative time was longer, and the number of lymph nodes was higher in the extended right hemicolectomy group (p < 0.001).
Conclusion We have shown that segmental resection of the splenic flexure is surgically and clinically suitable for the adequate management of operable cases of carcinoma of the splenic flexure.

Abstract
BACKGROUND The optimal elective colectomy in patients with splenic flexure tumor is debated. OBJECTIVE This study aimed to compare splenic flexure colectomy, left hemicolectomy, and subtotal colectomy for perioperative, histological, and survival outcomes in this setting. DESIGN This is a multicenter retrospective cohort study. SETTING Patients diagnosed with nonmetastatic splenic flexure tumor who underwent elective colectomy were included. PATIENTS Between 2006 and 2014, 313 consecutive patients were operated on in 15 French Research Group of Rectal Cancer Surgery centers. INTERVENTIONS Propensity score weighting was performed to compare short- and long-term outcomes. MAIN OUTCOME MEASURES The primary end point was disease-free survival. Secondary end points included overall survival, quality of surgical resection, overall postoperative morbidity, surgical postoperative morbidity, and rate of anastomotic leakage. RESULTS The most performed surgery was splenic flexure colectomy (59%), followed by subtotal colectomy (23%) and left hemicolectomy (18%). Subtotal colectomy was more often performed by laparotomy compared with splenic flexure colectomy and left hemicolectomy (93% vs 61% vs 56%, p < 0.0001), and was associated with a longer operative time (260 minutes (120-460) vs 180 minutes (68-440) vs 217 minutes (149-480), p < 0.0001). Postoperative morbidity was similar between the 3 groups, but the median length of hospital stay was significantly longer after subtotal colectomy (13 days (5-56) vs 10 (4-175) vs 9 (4-55), p = 0.0007). The median number of harvested lymph nodes was significantly higher after subtotal colectomy compared with splenic flexure colectomy and left hemicolectomy (24 (8-90) vs 15 (1-81) vs 16 (3-52), p < 0.0001). The rate of stage III disease and the number of patients treated by adjuvant chemotherapy were similar between the 3 groups. There was no difference in terms of disease-free survival and overall survival between the 3 procedures. LIMITATIONS The study was limited by its retrospective design. CONCLUSIONS In the elective setting, splenic flexure colectomy is safe and oncologically adequate for patients with nonmetastatic splenic flexure tumor. However, given the oncological clearance after splenic flexure colectomy, it seems that the debate is not completely closed. See Video Abstract at http://links.lww.com/DCR/B703. CUL ES LA COLECTOMA ELECTIVA PTIMA PARA EL CNCER DE NGULO ESPLNICO FIN DEL DEBATE UN ESTUDIO MULTICNTRICO DEL GRUPO GRECCAR CON UN ANLISIS DE PUNTAJE DE PROPENSIN ANTECEDENTES:La colectomía electiva óptima en pacientes con tumores del ángulo esplénico continua en debate.OBJETIVO:Comparar la colectomía de ángulo esplénico, hemicolectomía izquierda y colectomía subtotal para los resultados perioperatorios, histológicos y de supervivencia en este escenario.DISEÑO:Estudio de cohorte retrospectivo multicéntrico.ESCENARIO:Se incluyeron pacientes diagnosticados de tumores del ángulo esplénico no metastásicos que se sometieron a colectomía electiva.PACIENTES:Entre 2006 y 2014, 313 pacientes consecutivos fueron intervenidos en 15 centros GRECCAR.INTERVENCIONES:Se realizó una ponderación del puntaje de propensión para comparar los resultados a corto y largo plazo.PRINCIPALES MEDIDAS DE RESULTADO:El criterio de valoración principal fue la supervivencia libre de enfermedad. Los criterios de valoración secundarios incluyeron la supervivencia general, la calidad de la resección quirúrgica, la morbilidad posoperatoria general, la morbilidad posoperatoria quirúrgica y la tasa de fuga anastomótica.RESULTADOS:La cirugía más realizada fue la colectomía del ángulo esplénico (59%), seguida de la colectomía subtotal (23%) y la hemicolectomía izquierda (18%). La colectomía subtotal se realizó con mayor frecuencia mediante laparotomía en comparación con la colectomía de ángulo esplénico y la hemicolectomía izquierda (93% frente a 61% frente a 56%, p <0.0001), y se asoció con un tiempo quirúrgico más prolongado (260 min [120-460] frente a 180 min [68-440] frente a 217 min [149-480], p <0.0001). La morbilidad posoperatoria fue similar entre los tres grupos, pero la duración media de la estancia hospitalaria fue significativamente más prolongada después de la colectomía subtotal (13 días [5-56] frente a 10 [4-175] frente a 9 [4-55], p = 0.0007). La mediana del número de ganglios linfáticos extraídos fue significativamente mayor después de la colectomía subtotal en comparación con la colectomía del ángulo esplénico y la hemicolectomía izquierda (24 [8-90] frente a 15 [1-81] frente a 16 [3-52], p <0.0001). La tasa de enfermedad en estadio III y el número de pacientes tratados con quimioterapia adyuvante fueron similares entre los 3 grupos. No hubo diferencias en términos de supervivencia libre de enfermedad y supervivencia general entre los 3 procedimientos.LIMITACIONES:El estudio estuvo limitado por su diseño retrospectivo.CONCLUSIONES:En un escenario electivo, la colectomía del ángulo esplénico es segura y oncológicamente adecuada para pacientes con tumores del ángulo esplénico no metastásicos. Sin embargo, dado el aclaramiento oncológico tras la colectomía del ángulo esplénico, parece que el debate no está completamente cerrado. Consulte Video Resumen en http://links.lww.com/DCR/B703.

Abstract
Introduction Fewer than 10% of colon cancers are found at the splenic flexure. A standard surgical approach to these cancers has not been defined. The goal of this study was to compare lymph node harvest and post-operative morbidity between segmental resection and formal left hemicolectomy for splenic flexure colon cancers. Method Patients diagnosed with a splenic flexure cancer were identified from the 2012–2018 ACS-NSQIP colectomy-targeted database. Patients were categorized based on type of surgical resection – left hemicolectomy with colorectal anastomosis or segmental colectomy with colocolonic anastomosis. Demographic, clinicopathologic, and post-operative outcomes were compared between groups. Factors independently associated with lymph node harvest, operative time, and post-operative morbidity were investigated by linear and binomial logistic regression models. Results A total of 3,049 patients underwent colectomy for a splenic flexure cancer. Of these, 83.6% had a segmental colectomy and 73% were performed by a minimally invasive approach. T- and N-stage did not differ between segmental and left hemicolectomy groups (p = 0.703 and p = 0.429, respectively). Inadequate nodal harvest (< 12 nodes) was infrequent and similar between the two procedures (7.4% vs. 9.1%, p = 0.13). Operative time was significantly shorter for segmental colectomy (213 ± 83.5 min vs. 193 ± 84.1 min, p < 0.0001) and major morbidity was similar between the two surgical techniques (8.4% vs. 8.9%, p = 0.75). After accounting for demographic, clinicopathologic, and operative factors, binomial logistic regression showed that type of procedure was not significantly associated with LN harvest (OR 0.80, 95%CI 0.54–1.17) or major morbidity (OR 1.17, 95%CI 0.36–3.81). However, on linear regression, segmental splenic flexure resection was associated with shorter operative time (estimate 20.29, 95%CI 12.61–27.97, p < 0.0001). Conclusion Splenic flexure resection for colon cancer is associated with an adequate lymph node harvest. Compared to a formal left hemicolectomy, a segmental resection also has a shorter operative time with equivalent post-operative morbidity.

Abstract
Management of malignant left-sided colonic obstruction remains challenging and requires a stoma in 40-65% of patients. In those with obstructive splenic flexure colon cancer (OSFCC), a debate still exists regarding the most appropriate surgery. The aim of this muticenter study was to report and compare the different surgical procedures in OSFCC patients with a special focus on operative and histological characteristics and survival outcomes including 12-month stoma-free survival. Between 2000 and 2015, 2325 patients were treated for obstructive colon cancer in centers members of the French National Surgical Association (AFC). Among them, 198 underwent surgery for OSFCC and were retrospectively analyzed. Patients with OSFCC and proximal colonic ischemia or perforation were excluded. Four procedures were performed: decompressing stoma (DS, 39%), splenic flexure colectomy (SFC, 39%), subtotal colectomy (STC, 17%,) and left hemicolectomy (LHC, 5%). All patients treated with LHC underwent a Hartmann's procedure. There was no significant difference between groups for postoperative mortality and morbidity. Hospital stay was significantly longer after DS. The length of the specimen, longitudinal resection margins and number of harvested lymph nodes were significantly higher in the STC group. There was no difference for overall and disease-free survival. Stoma-free survival was significantly lower after LHC (62%) in comparison with the other groups (p < 0.0001). At the end of follow-up, 50% of patients who underwent LHC had a permanent stoma. In OSFCC patients without proximal colonic ischemia or peritonitis, LHC should no longer be recommended due to a high risk of permanent stoma.

Abstract
Purpose Splenic flexure colon cancer (SFCC) is a rare disease that accounts for 2%–8% of colorectal cancers, and the extent of surgery and resection is still debatable. There have also been few studies on the safety and feasibility of laparoscopic surgery for SFCC. The purpose of this study is to evaluate outcomes and prognoses of surgery for SFCC. Methods We included patients with stage 1 to 3 who had undergone laparoscopic surgery for distal transverse-to-sigmoid colon cancer at 2 hospitals from March 2004 to December 2016 and collected data by retrospective design. We defined SFCC as being cancer between distal transverse and proximal descending colon. The short- and long-term outcomes of the anterior resection (AR) group (those patients who had undergone laparoscopic AR for mid and distal descending to sigmoid colon cancer) and the left colon resection (LR) group (those who had undergone laparoscopic segmental left colectomy for SFCC) were compared using propensity score matching. Results The median follow-up period was 60 months. The numbers of subjects in the AR and the LR groups were 948 and 118. After 2:1 propensity score matching, 236 vs. 118 patients were selected. There was no significant difference in 5-year disease-free survival (80.7% vs. 78.6%, P = 0.607), and both the 5-year overall survival (89.2% vs. 88.2%, P = 0.563) as well as short-term outcomes showed no statistical difference in most of the variables. Conclusion Laparoscopic segmental left colectomy can be one option among the standard procedures for SFCC.

Abstract
Introduction This How-I-Do-It article presents a modified Deloyers procedure by mean of the case of a 67-year-old female with adenocarcinoma extending for a long segment and involving the splenic flexure and proximal descending colon who underwent a laparoscopic left extended hemicolectomy (LELC) with derotation of the right colon and primary colorectal anastomosis. Background While laparoscopic extended right colectomy is a well-established procedure, LELC is rarely used (mainly for distal transverse or proximal descending colon carcinomas extending to the area of the splenic flexure). LELC presents several technical challenges which are demonstrated in this How-I-Do-It article. Technique and methods Firstly, the steps needed to mobilize the left colon and procure a safe approach to the splenic flexure are described, especially when a tumor is closely related to it. This is achieved by mobilization and resection of the descending colon, while maintaining a complete mesocolic excision to the level of the duodenojejunal ligament for the inferior mesenteric vein and flush to the aorta for the inferior mesenteric artery. Subsequently, we depict the adjuvant steps required to enable a primary anastomosis by trying to mobilize the transverse colon and release as much of the mesocolic attachments at the splenic flexure area. Finally, we present the rare instance when a laparoscopic derotation of the ascending colon is required to provide a tension-free anastomosis. The resection is completed by delivery of the fully derotated ascending colon and hepatic flexure through a suprapubic mini-Pfannenstiel incision. The primary colorectal anastomosis is subsequently fashioned in a tension-free way and provides for a quick postoperative recovery of the patient. Results This modified Deloyers procedure preserves the middle colic since the fully mobilized mesocolon allows for a tension-free anastomosis while maintaining better blood supply to the mobilized stump. Also, by eliminating the need for a mesenteric window and the transposition of the caecum, we allow the small bowel to rest over the anastomosis and the mobilized transverse colon and reduce the possibility of an internal herniation of the small bowel into the mesentery. Conclusions Laparoscopic derotation of the right colon and a partial, modified Deloyers procedure preserving the middle colic vessels are feasible techniques in experienced hands to provide primary anastomosis after LELC with improved functional outcome. Nevertheless, it is important to consider anatomical aspects of the left hemicolectomy along with oncological considerations, to provide both a safe oncological resection along with good postoperative bowel function.

Abstract
AIM OF THE STUDY This European multicenter study aims to compare the results of laparoscopic versus laparotomy approach for the resection of splenic flexure colon carcinoma (SFC). PATIENTS AND METHODS Patients with SFC who required curative resection by laparoscopy (LAP) or laparotomy (OPEN) between 2000 and 2018 were included. Three types of interventions were considered: extended right hemi-colectomy, left hemi-colectomy and splenic flexure resection. The LAP and OPEN groups were matched according to propensity score and compared with Chi-square, Mann-Whitney tests, and multivariate regression models. Overall survival and recurrence-free survival were assessed using the Kaplan-Meier method. RESULTS The study population consisted of 399 patients, including 297 operated by LAP and 102 by OPEN. Extended right hemi-colectomy was performed in 35.8% of cases, left hemi-colectomy in 32.8% and splenic flexure resection in 31.4%. After propensity score matching, the LAP (n=64) and OPEN (n=64) groups were comparable for all pre-operative variables and tumor characteristics. The LAP group showed less blood loss and a shorter interval to return of transit and feeding compared to the OPEN group, regardless of the resection technique. There were no differences between the groups in terms of overall survival and 5-year recurrence-free survival. CONCLUSION These results support the application of laparoscopy for the resection of SFC.

Abstract
AIM Surgical resection of splenic flexure cancers (SFCs) is technically demanding due to the complex regional anatomy, characterized by the presence of embryological adhesions, close proximity to the pancreas and spleen, and a highly heterogeneous arterial supply and lymphatic drainage. The accessory middle colic artery (AMCA) is increasingly being recognized as an important source of blood supply to the splenic flexure. The aim of this study is to determine the prevalence and anatomical features of the AMCA. METHOD A systematic search of the scientific literature was conducted on PubMed and Embase from inception to November 2020 to identify potentially eligible studies. Data were extracted and prevalence was pooled into a meta-analysis using MetaXL and Meta-Analyst software. RESULTS A total of 16 studies (n = 2203 patients) were included. The pooled prevalence (PP) of the AMCA was 25.4% (95% CI 18.1-33.4). Its prevalence was higher in patients without a left colic artery (LCA) (PP = 83.2%; 95% CI 70.4-93.1). The commonest origin for the AMCA was the superior mesenteric artery (PP = 87.9%; 95% CI 86.4-90.7). The AMCA shared a common trunk/gave rise to pancreatic branches in 23.1% of cases (95% CI 15.3-31.9). CONCLUSION The AMCA contributes to the vascularization of the splenic flexure in approximately 25% of individuals, and may be an important feeder artery to SFCs, especially in the absence of a LCA. Preoperative identification of this artery is important to ensure optimal surgery for SFC and minimize complications.

Abstract
BACKGROUND The optimal surgical approach for distal transverse colon cancer has not been well established. This study aimed to evaluate the oncologic safety of left colectomy with a modified complete mesocolic excision for distal transverse colon cancer as compared with descending colon cancer. MATERIAL AND METHODS This study involved 383 patients who underwent left colectomy with modified complete mesocolic excision for non-metastatic distal transverse and splenic flexure colon (transverse group, N = 110) and descending colon cancer (descending group, N = 237) from 3 institutions. Recurrence-free survival (RFS) and overall survival (OS) were compared between the two groups. RESULTS Baseline characteristics between the two groups were similar except for the length of the distal margin (transverse group = 11.0 cm vs descending group = 9.0 cm, p = 0.004). During a median follow-up of 47.0 months, RFS and OS were not different between the transverse and descending groups (5-year RFS: 82% vs 71%, p = 0.139; 5-year OS: 83% vs 79%, p = 0.416, respectively). In multivariable analysis, RFS and OS were not different between the two groups (transverse group vs. descending group: adjusted hazard ratio [aHR] = 1.557, 95% CI = 0.786-3.084, p = 0.204; aHR = 1.251, 95% CI = 0.530-2.952, p = 0.609). CONCLUSION The oncologic outcomes of left colectomy with a modified complete mesocolic excision of distal transverse colon cancer were comparable to those of descending colon cancer. Left colectomy with a modified complete mesocolic excision can be an acceptable surgical treatment for distal transverse colon cancer.

Laparoscopic complete mesocolic excision with central vascular ligation for splenic flexure colon cancer: short- and long-term outcomes. Surg Endosc 2021; 36:2661-2670. [PMID: 34031741 PMCID: PMC8921072 DOI: 10.1007/s00464-021-08559-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Accepted: 05/11/2021] [Indexed: 12/01/2022]
Abstract
Background Complete mesocolic excision (CME) with central vascular ligation (CVL) for colon cancer is an essential procedure for improved oncologic outcomes after surgery. Laparoscopic surgery for splenic flexure colon cancer was recently adopted due to a greater understanding of surgical anatomy and improvements in surgical techniques and innovative surgical devices. Methods We retrospectively analyzed the data of patients with splenic flexure colon cancer who underwent laparoscopic CME with CVL at our institution between January 2005 and December 2017. Results Forty-five patients (4.8%) were enrolled in this study. Laparoscopic CME with CVL was successfully performed in all patients. The median operative time was 178 min, and the median estimated blood loss was 20 g. Perioperative complications developed in 6 patients (13.3%). The median postoperative hospital stay was 9 days. According to the pathological report, the median number of harvested lymph nodes was 15, and lymph node metastasis developed in 14 patients (31.1%). No metastasis was observed at the root of the middle colic artery or the inferior mesenteric artery. The median follow-up period was 49 months. The cumulative 5-year overall survival and disease-free survival rates were 85.9% and 84.7%, respectively. The cancer-specific survival rate in stage I-III patients was 92.7%. Recurrence was observed in 5 patients (11.1%), including three patients with peritoneal dissemination and two patients with distant metastasis. Conclusions Laparoscopic CME with CVL for splenic flexure colon cancer appears to be oncologically safe and feasible based on the short- and long-term outcomes in our study. However, it is careful to introduce this procedure to necessitate the anatomical understandings and surgeon’s skill. The appropriate indications must be established with more case registries because our experience is limited.

Primary tumor resection improves prognosis of unresectable carcinomas of the transverse colon including flexures with liver metastasis: a preliminary population-based analysis. BMC Cancer 2021; 21:503. [PMID: 33957871 PMCID: PMC8101189 DOI: 10.1186/s12885-021-08157-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Accepted: 04/05/2021] [Indexed: 11/19/2022] Open
Abstract
Purpose Studies on unresectable colorectal cancer liver metastasis(CRLM) rarely analyze the prognosis of the patients from the point of colonic subsites. We aimed to evaluate the effect of primary tumor resection (PTR) and different scope of colectomy on the prognosis of patients with unresectable transverse colon cancer liver metastasis (UTCLM), hepatic flexure cancer liver metastasis (UHFLM), and splenic flexure cancer liver metastasis (USFLM). Patients and methods The patients were identified from the Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2015. Cox proportional hazards regression models were used to identify prognostic factors of overall survival (OS) and cause-specific survival (CSS). Kaplan-Meier analyses and log-rank tests were conducted to assess the effectiveness of PTR on survival. Results In total, this study included a cohort of 1960 patients: 556 cases of UHFLM, 1008 cases of UTCLM, and 396 cases of USFLM. The median survival time of whole patients was 11.0 months, ranging from 7.0 months for UHFLM patients to 15.0 months for USFLM patients. USFLM patients had the best OS and CSS, followed by UTCLM patients. UHFLM patients had the worst OS and CSS (All P < 0.001). PTR could improve the OS and CSS of UTCLM, UHFLM, and USFLM (All P < 0.001). Subgroups analysis revealed that USFLM patients with tumor size≤5 cm and negative CEA had not demonstrated an improved OS and CSS after PTR. Multivariate analysis showed that PTR and perioperative chemotherapy were common independent prognostic factors for UHFLM, UTCLM, and USFLM patients. There was no difference between segmental colon resection and larger colon resection on CSS of UHFLM, UTCLM, and USFLM patients. Conclusions We confirmed the different survival of patients with UTCLM, UHFLM, and USFLM, and for the first time, we proved that PTR could provide survival benefits for patients with unresectable CRLM from the perspective of colonic subsites of transverse colon, hepatic flexure, and splenic flexure. Besides, PTR may not improve the prognosis of USFLM patients with CEA- negative or tumor size≤5 cm. For oncologic outcomes, we concluded that segmental colon resection seemed an effective surgical procedure for UTCLM, UHFLM, and USFLM.

Abstract
Background The effectiveness of surgical treatment for splenic flexure carcinomas (SFCs) in emergency settings remains unexplored. This study aims to compare the perioperative and long-term outcomes of different alternatives for emergency SFC resection. Method This multicenter retrospective study was based on the SFC Study Group database. For the present analysis, SFC patients were selected if they had received emergency surgical resection with curative intent between 2000 and 2018. Extended right colectomy (ERC), left colectomy (LC), and segmental left colectomy (SLC) were evaluated and compared. Results The study sample was composed of 90 SFC patients who underwent emergency ERC (n = 55, 61.1%), LC (n = 18, 20%), or SLC (n = 17, 18.9%). Bowel obstruction was the most frequent indication for surgery (n = 75, 83.3%), and an open approach was chosen in 81.1% of the patients. A higher incidence of postoperative complications was observed in the ERC group (70.9%) than in the LC (44.4%) and SLC groups (47.1%), with a significant procedure-related difference for severe postoperative complications (Dindo-Clavien ≥ III; adjusted odds ratio for ERC vs. LC:7.23; 95% CI 1.51-34.66; p = 0.013). Anastomotic leakage occurred in 8 (11.2%) patients, with no differences between the groups (p = 0.902). R0 resection was achieved in 98.9% of the procedures, and ≥ 12 lymph nodes were retrieved in 92.2% of patients. Overall and disease-free survival rates at 5 years were similar between the groups and were significantly associated with stage pT4 and the presence of synchronous metastases. Conclusion In the emergency setting, ERC and open surgery are the most frequently performed procedures. ERC is associated with increased odds of severe postoperative complications when compared to more conservative SFC resections. Nonetheless, all the alternatives seem to provide similar pathologic and long-term outcomes, supporting the oncological safety of more conservative resections for emergency SFCs.

Abstract
AIM To perform a network meta-analysis of the current literature to evaluate the short-term and long-term outcomes of four operations for splenic flexure tumors. METHODS An electronic literature search of PubMed, Baidu Scholar, EMBASE, and Cochrane Central Register of Controlled Trials databases was performed up to August 2020. A Bayesian network meta-analysis was utilized to compare the outcomes involved in subtotal colectomy (STC), extended right hemicolectomy (ERHC), standard left hemicolectomy (LHC), and splenic flexure colectomy (SFC) by using R software. RESULTS A total of 10 non-randomized studies were included in this meta-analysis. There was no statistically significant difference among these 4 surgical techniques in terms of the utilization rate of minimally invasive surgery, reoperative surgery, anastomotic dehiscence, mortality, the proportion of patients with the number of lymph nodes harvested ≥ 12, local recurrence, distant recurrence and overall survival. Although ERHC was associated with a higher risk of postoperative ileus (ERHC vs SFC, OR = 6.4, 95% CI 1.4-45.0, P = 0.019), it has an advantage of a higher rate of primary anastomosis (ERHC vs LHC, OR = 4.2, 95% CI 1.3-18.0, P = 0.019) and a non-significant trend for lower anastomotic dehiscence when compared with more restrict resections. CONCLUSION SFC, LHC, ERHC and STC for the curative resection of splenic flexure tumors provide similar survival. An individualized surgical plan considering both long-term and short-term outcomes is necessary to select the appropriate operations.

[PMID: 33492511 PMCID: PMC8741724 DOI: 10.1007/s00464-020-08242-8] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Accepted: 12/16/2020] [Indexed: 12/14/2022]
Abstract
Background The impact of the position of the middle colic artery (MCA) bifurcation
and the trajectory of the accessory MCA (aMCA) on adequate lymphadenectomy when
operating colon cancer have as of yet not been described and/or analysed in the
literature. The aim of this study was to determine the MCA bifurcation position to
anatomical landmarks and to assess the trajectory of aMCA. Methods The colonic vascular anatomy was manually reconstructed in 3D from
high-resolution CT datasets using Osirix MD and 3-matic Medical and analysed. CT
datasets were exported as STL files and supplemented with 3D printed models when
required. Results Thirty-two datasets were analysed. The MCA bifurcation was left to the
superior mesenteric vein (SMV) in 4 (12.1%), in front of SMV in 17 (53.1%) and right
to SMV in 11 (34.4%) models. Median distances from the MCA origin to bifurcation were
3.21 (1.18–15.60) cm. A longer MCA bifurcated over or right to SMV, while a shorter
bifurcated left to SMV (r = 0.457, p = 0.009). The main MCA direction was towards right in
19 (59.4%) models. When initial directions included left, the bifurcation occurred
left to or anterior to SMV in all models. When the initial directions included right,
the bifurcation occurred anterior or right to SMV in all models. The aMCA was found
in 10 (31.3%) models, following the inferior mesenteric vein (IMV) in 5 near the
lower pancreatic border. The IMV confluence was into SMV in 18 (56.3%), splenic vein
in 11 (34.4%) and jejunal vein in 3 (9.4%) models. Conclusion Awareness of the wide range of MCA bifurcation positions reported is
crucial for the quality of lymphadenectomy performed. The aMCA occurs in 31.3% models
and its trajectory is in proximity to the lower pancreatic border in one half of
models, indicating that it needs to be considered when operating splenic flexure
cancer. Supplementary information The online version of this article (10.1007/s00464-020-08242-8) contains supplementary material, which is available to authorized

Abstract
Transverse colon, owing its origin to midgut and hindgut and harbouring a flexure at both ends, continues to pose a surgical challenge. When compared to the rest of the colon, transverse colon adenocarcinoma is relatively uncommon. These cancers usually present late and lie in close proximity to the stomach, omentum, and pancreas. Adequate lymphadenectomy entails dissection around and ligation of the middle colic vessels. Hence, resectional surgery for transverse colon carcinoma is considered difficult. This is more so because of the variation of arterial and venous anatomy. From this perspective, the surgeon is tempted to perform a more radical operation like extended right or left hemicolectomy to secure an adequate lymphadenectomy. Such a cancer has also been dealt with a more limited transverse colectomy with colo-colic anastomosis. For all these reasons, patients with transverse colon adenocarcinoma were excluded from randomised trials which compared laparoscopic resection with traditional open operation. Surgical literature is yet to establish a definite operation for transverse colon cancer and the exact procedure is often dictated by surgeon's preference. This is primarily because this is an uncommon cancer. The rapid adoption of laparoscopic operation favoured extended colectomy as transverse colectomy can be difficult by minimally invasive technique. However, in the recent past, cohort studies and meta-analyses have shown equivalent oncological outcome between transverse colectomy and extended colectomy. It is time to resurrect transverse colectomy and consider it equivalent to its radical counterpart for cancers around the mid-transverse colon.

Abstract
BACKGROUND Colorectal cancer seldom presents at the splenic flexure. Small series on left flexure tumors reported a high occurrence of negative prognostic factors called into question as causes of poor prognosis. However, because of the small number of cases, no definite conclusions can be drawn. OBJECTIVE The aim of this study was to compare clinical-pathologic characteristics and short- and long-term outcomes of left flexure tumors with other colonic locations. DESIGN This was a retrospective analysis of consecutive patients who underwent surgery for tumors at the splenic flexure. Each tumor was paired in a 1 to 1 fashion with a right-sided and sigmoid tumor. SETTINGS The study was conducted in 10 international centers. PATIENTS A total of 641 patients with left flexure tumors were included in the study. MAIN OUTCOME MEASURES Overall survival and cancer-specific survival were measured. RESULTS Left flexure tumors presented more frequently with stenosis (30.5%; p < 0.001), with lesions infiltrating beyond the serosa (21.9%; p = 0.001) and with a high rate of mucinous histology (8.8%; p = 0.001). Looking at long-term prognosis, no differences were observed among the 3 groups, both considering overall and cancer-specific survival. However, left flexure tumors recurred more frequently as peritoneal carcinomatosis (20.6%; p < 0.001). LIMITATIONS This study was limited because of its retrospective nature. CONCLUSIONS Although left flexure tumors display several negative prognostic factors, they are not characterized by a worse prognosis compared with other colon cancer locations.

Abstract
AIM The aim of this work was to compare the outcomes of extended right hemicolectomy (ERH), left hemicolectomy (LH) and segmental colectomy (SC) for the surgical management of splenic flexure tumours. METHOD In compliance with PRISMA statement standards, a systematic review was performed to identify all studies comparing outcomes of ERH, LH and SC for the surgical management of splenic flexure tumours. Primary outcomes included anastomotic leakage and all postoperative complications. The secondary outcomes included operative time, R0 resection, number of harvested lymph nodes, > 12 harvested lymph nodes, severe complications, postoperative mortality, paralytic ileus, wound infection, pancreatic fistula, intra-abdominal abscess, need for reoperation, length of hospital stay, 5-year overall survival and 5-year disease-free survival. The ROBINS-I tool and GRADE system were used to assess the risk of bias and certainty of evidence, respectively. RESULTS Analysis of 956 patients from seven observational studies showed that ERH was associated with more paralytic ileus than LH (OR 2.74, P = 0.002) and SC (OR 6.67, P < 0.0001) and the operative time was shorter in SC than in ERH (mean difference 25.48, P < 0.0001) and LH (mean difference -17.94, P = 0.0002). There were no differences between ERH, LH and SC in terms of anastomotic leakage, postoperative complications, R0 resection, severe complications, postoperative mortality, wound infection, pancreatic fistula, intra-abdominal abscess, need for reoperation, length of hospital stay, > 12 harvested lymph nodes, 5-year overall survival and 5-year disease-free survival. CONCLUSIONS The available evidence, limited to observational studies, suggests that there is no difference between ERH, LH and SC in terms of postoperative morbidity and mortality, lymph node yield and cancer survival. Randomized controlled trials are required for definite conclusions.

Abstract
BACKGROUND What qualifies as optimal lymph node (LN) dissection in the surgical management of splenic flexure colon cancer (SFCC) still remains controversial because few studies have evaluated the distribution of LN metastasis of SFCC. The aim of this study was to clarify detailed distribution of LN metastasis and long-term outcomes of SFCC. METHODS This retrospective study enrolled patients who had curative colectomy for primary transverse or descending colon cancer of pathological stage I, II, or III at a single high-volume cancer center between April 2002 and December 2018. The 538 eligible patients were divided into three groups: patients with SFCC (SFCC group, n = 168), patients with proximal transverse colon cancer (PTCC group, n = 290), and patients with distal descending colon cancer (DDCC group, n = 80). LNs were classified into horizontal (pericolic) and vertical (intermediate and main) nodes. Intermediate and main LN station numbers were defined according to the Japanese Society for Cancer of the Colon and Rectum classification. Distributions of LN metastasis and long-term outcomes were compared. RESULTS In the SFCC group, the mean age was 67.3 ± 10.5 years and 110 patients (65.5%) were male. The proportion of patients with LN metastasis in the intermediate or main region was significantly lower in the SFCC group (8%) than in the PTCC (37%) (p < 0.01) or DDCC group (29%) (p < 0.01) in pathological stage III patients. In the SFCC group, the incidence of pericolic LN metastasis on the oral side of tumor (43%) was significantly higher than in the PTCC group (21%) (p < 0.01) and was similar to that in the DDCC group (42%) (p = 0.51), while in the SFCC group, the incidence of pericolic LN metastasis on the anal side of tumor (17%) was lower than in the PTCC group (31%) and was also similar to that in the DDCC group (21%). There were no significant differences in disease-specific survival rates among all groups. CONCLUSIONS LN metastasis occurred mainly in the pericolic region, especially on the oral side of the tumor in SFCC. It may, therefore, be important to have an adequate bowel resection margin, especially on the oral side, for SFCC.

Abstract
Patients with resectable tumor, either in the body or the tail of the pancreas, and cancer patients with a primary tumor adjacent to the splenic vasculature frequently undergo a splenectomy as standard of care during resection. The spleen provides an unutilized source of lymphocytes with potential utility for adoptive cellular therapy (ACT). In this report, spleen and peripheral blood (PB) cells from cancer patients were compared to one another and normal PB by flow cytometry with a focus on CD8+ T-cells, memory phenotype, and their relative expression of checkpoint proteins including program death ligand-1 (PD1). PD1 is both an activation marker for T-cells including antigen (Ag) specific responses, as well as a marker of T-cell exhaustion associated with co-expression of other checkpoint molecules such as lymphocyte activating gene-3 (LAG-3) and T-cell immunoglobulin and mucin domain containing-3 (TIM-3). In summary, the spleen is a rich source of CD8+PD1+ T-cells, with an 8-fold higher frequency compared to the PB. These CD8+ T-cells are predominantly central and transitional memory T-cells with associated effector phenotypes and low expression of TIM-3 and LAG-3 with potential utility for ACT".

Abstract
BACKGROUND The surgical resection of the splenic flexure carcinoma (SFC) is challenging and the optimal surgical procedure for SFCs remains a matter of debate. The present study aimed to compare in a multicenter European sample of patients the short- and long-term outcomes of extended right (ERC) vs. left (LC) vs. segmental left colectomy (SLC) for SFCs. METHODS This retrospective multicenter study analyzed the surgical and oncological outcomes of SFC patients undergoing elective curative intent surgery between 2000 and 2018. Descriptive and exploratory analyses were first conducted on the whole sample. Outcomes of the different procedures (ERC vs. LC vs. SLC) were then compared using propensity score matching for multilevel treatment. Overall (OS) and disease-free survival (DFS) were evaluated by Kaplan-Meier method. RESULTS From a total of 399 SFC patients, 143 (35.8%) underwent ERC, 131 (32.8%) underwent LC, and 125 (31.4%) underwent SLC. Overall, 297 (74.4%) were laparoscopic procedures. An increase in operative time, time to flatus, time to regular diet, and hospital stay was observed with the progressive extension of SFC resection. ERC was associated with significantly increased risk of postoperative ileus compared to both LC and SLC. A significantly greater number of lymph nodes were retrieved by ERC, but the objective of at least 12 retrieved lymph nodes was achieved in 85% of patients, without procedure-related differences. No differences were observed in OS or DFS between ERC, LC, and SLC. CONCLUSION The present study supports the resection of SFCs by colon-sparing surgical techniques, such as SLC.
