Abstract
PURPOSE Studies of unresectable colorectal cancer pulmonary metastasis (CRPM) have rarely analyzed patient prognosis from the perspective of colonic subsites. This study aimed to evaluate the effects of primary tumor resection (PTR) on the prognosis of patients with unresectable pulmonary metastases of transverse colon cancer pulmonary metastasis (UTCPM), hepatic flexure cancer pulmonary metastasis (UHFPM), and splenic flexure cancer pulmonary metastasis (USFPM). METHODS Patients were identified from the Surveillance, Epidemiology, and End Results database between 2000 and 2018. The Cox proportional hazards regression models were used to identify prognostic factors of overall survival (OS) and cause-specific survival (CSS). The Kaplan-Meier analyses and log-rank tests were conducted to assess the effectiveness of PTR on survival. RESULTS This study included 1294 patients: 419 with UHFPM, 636 with UTCPM, and 239 with USFPM. Survival analysis for OS and CSS in the PTR groups, showed that there were no statistical differences in the the UHFPM, UTCPM, and USFPM patients. There were statistical differences in the UHFPM, UTCPM, and USFPM patients for OS and CSS. Three non-PTR subgroups showed significant statistical differences for OS and CSS. CONCLUSION We confirmed the different survival rates of patients with UTCPM, UHFPM, and USFPM and proved for the first time that PTR could provide survival benefits for patients with unresectable CRPM from the perspective of the colonic subsites of the transverse colon, hepatic flexure, and splenic flexure.

Abstract
BACKGROUND AND OBJECTIVE Some colorectal surgeons advocate routine splenic flexure mobilization (SFM) when performing anterior resection for rectal cancer to ensure a tension-free anastomosis. Meta-analyses of smaller studies suggest that this approach does not influence anastomotic leakage rates, but larger multicentre studies are needed to confirm the safety of a selective strategy. The aim of this study is to evaluate the impact of SFM on anastomotic leakage. METHODS This is a retrospective multicentre cohort study, comprising 1109 patients operated with anterior resection for rectal cancer in 2014-2018. Exposure was SFM, while anastomotic leakage within a year constituted the outcome. Stratified analyses were performed for type of mesorectal excision and surgical approach, as well as sensitivity analysis considering vascular tie placement. Multivariable Cox regression with hazard ratios (HRs) and 95% confidence intervals (CIs) was employed to adjust for confounding, while multiple imputation was used for missing data. RESULTS SFM was performed in 381 patients (34.4%). Anastomotic leakage occurred in 83 (21.8%) and 123 (20.3%) patients operated with and without SFM, respectively. SFM was neither clearly detrimental nor beneficial regarding anastomotic leakage (adjusted HR = 0.82; 95% CI: 0.59-1.15), with no apparent differences for total or partial mesorectal excision and minimally invasive or open surgery. Concurrent high vascular ligation did not impact these results, and there was no evidence of interaction from centers with a more common use of SFM. CONCLUSIONS SFM did not seem to influence the risk of anastomotic leakage after anterior resection for rectal cancer, regardless of type of mesorectal excision, use of minimally invasive surgery, or high vascular ligation.

Abstract
AIM The splenic flexure has variable vascular anatomy, and the details of the venous forms are not known. In this study, we report the flow pattern of the splenic flexure vein (SFV) and the positional relationship between the SFV and arteries such as the accessory middle colic artery (AMCA). METHODS This was a single-centre study using preoperative enhanced CT colonography images of 600 colorectal surgery patients. CT images were reconstructed into 3D angiography. SFV was defined as a vein flowing centrally from the marginal vein of the splenic flexure visible on CT. AMCA was defined as the artery feeding the left side of the transverse colon, separate from the left branch of the middle colic artery. RESULTS The SFV returned to the inferior mesenteric vein (IMV) in 494 cases (82.3%), the superior mesenteric vein in 51 cases (8.5%) and the splenic vein in seven cases (1.2%). The AMCA was present in 244 cases (40.7%). The AMCA branched from the superior mesenteric artery or its branches in 227 cases (93.0% of cases with existing AMCA). In the 552 cases in which the SFV returned to the IMV, superior mesenteric vein or splenic vein, the left colic artery was the most frequent artery accompanying the SFV (42.2%), followed by the AMCA (38.1%) and the left branch of the middle colic artery (14.3%). CONCLUSIONS The most common flow pattern of the vein in the splenic flexure is from the SFV to IMV. The SFV is frequently accompanied by the left colic artery or AMCA.

Abstract
BACKGROUND/AIM This study aimed to evaluate the extent of lymph node dissection (LND) determined using preoperative Three-dimensional computed tomographic angiography (3D-CTA), in the management of splenic flexure colon cancer (SFC). PATIENTS AND METHODS In this retrospective, observational study, 61 patients who underwent preoperative 3D-CTA and laparoscopic complete mesocolic excision for SFC between December 2011 and December 2021 were identified at a tertiary care center in Japan. Preoperative 3D-CTA was used to confirm the feeding arteries, following which the extent of LND was determined. Left hemicolectomy was performed in cases requiring LND in the domains of the middle colic artery and left colic artery. In other cases, a partial colectomy (PC) that was defined as a segmental resection of the splenic flexure with LND in the domains of the feeding arteries was performed. Surgical and oncological outcomes were compared between PC and left hemicolectomy. RESULTS Preoperative 3D-CTA enabled the evaluation of the feeding artery in all patients. PC was performed in 51 patients (83.6%). Patients who underwent PC had a shorter operative time (p=0.03) and less blood loss (p=0.01). There was no difference in complications between the two groups. There was also no significant difference in 5-year overall survival, nor 3-year disease free survival. CONCLUSION Preoperative simulation using 3D-CTA has the potential to be useful in the identification of feeding arteries and determination of the oncologically adequate extent of LND for each patient.

Abstract
BACKGROUND Splenic flexure tumours (SFC) are uncommon and present at more advanced disease stages. The optimal surgical technique for SFC remains controversial. We sought to compare the short-term outcomes of a left hemicolectomy (LHC) versus an extended resection (subtotal colectomy, STC) for SFCs. METHODS A retrospective analysis using the Binational Colorectal Cancer Audit (BCCA) registry was performed. All patients with SFC who underwent elective or emergency surgery for a SFC between 2010 and 2021 were included. Primary outcomes included short-term inpatient complications. Secondary outcomes included survival outcomes. RESULTS Six hundred and ninety-nine patients underwent resections for SFCs. A LHC was more common, performed in 64.1%. Patients having a LHC were significantly older, with proportionally more LHCs done laparoscopically. Overall grade III/IV complications were similar between both operations. Prolonged ileus and return to theatre were significantly higher in patients undergoing a STC. On multivariate analysis, anastomotic leak and overall grade III/IV complications were not independently associated with the type of operation. There was no difference in medial survival based on type of operation. Higher tumour stage (Stage III/IV) were independently associated with worse survival. CONCLUSION Segmental and extended resections are both oncologically sound procedures for SFCs. Segmental resections are associated with lower rates of prolonged ileus.

Abstract
AIM Surgical treatment of splenic flexure cancer (SFC) still presents some debated issues, including the role of laparoscopic surgery. The literature is based on small single-centre series, while randomized controlled studies comparing open and laparoscopic treatment for colon cancer exclude SFC. This study aimed to determine the role of laparoscopic surgery in the treatment of SFC, comparing short- and long-term outcomes with open surgery. METHOD This was an international multicentre retrospective cohort study that analysed patients from 10 tertiary referral centres. From a cohort of 641 cases, 484 patients with Stage I-III SFC submitted to elective surgery with curative intent were selected. After 1:1 propensity score matching, 130 patients in the laparoscopic group (LapGroup) were compared with 130 patients in the open surgery group (OpenGroup). RESULTS After propensity score matching, the two groups were comparable for demographic and clinical parameters. OpenGroup presented a higher incidence of overall (P = 0.02) and surgery-related complications (P = 0.05) but a similar rate of severe complications (P = 0.75). Length of stay was notably shorter in the LapGroup (P = 0.001). Overall (P = 0.793) as well as cancer-specific survival (P = 0.63) did not differ between the two groups. CONCLUSIONS Elective laparoscopic surgery for Stage I-III SFC is feasible and associated with improved short-term postoperative outcomes compared to open surgery. Moreover, laparoscopic surgery appears to provide excellent long-term cancer outcomes.

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: Standardized protocols for laparoscopic surgery of splenic flexure cancer (SFC) have not been established yet. We described a standardized laparoscopic procedure for SFCs and examined its safety and feasibility. Methods: Laparoscopic colectomy for SFC was performed as follows. The sigmoid colon was mobilized to the descending mesocolon through the medial approach. After confirming the base of the inferior mesenteric artery, the left colic artery was dissected and resected at the base. Further dissection was carried out between the mesentery of the colon and the renal fascia until it exceeded the upper pole of the left kidney and the splenic flexure. The next dissection reached the white line at the lateral side and the sigmoid-descending colon junction. After making an incision at the greater omentum and gastrocolic ligament from the center of the transverse colon to the splenic flexure, the transverse mesocolon base was dissected from the inside splenic flexure for complete mobilization. This was performed by approaching from four directions toward the splenic flexure. Intestinal resection and anastomosis are performed. Results: This procedure was performed in 70 patients with splenic flexure colon cancer (mean age 70 years). The mean operative time was 190 minutes, and the mean blood loss was 2.0 mL. No notable perioperative or postoperative complications were noted. Conclusions: Safe mobilization of the splenic flexure can be achieved by approaching from four directions, and standardization of left colectomy can facilitate complete mesenteric excision.

Abstract
AIM Recently, the accessory middle colic artery (AMCA) has been recognized as the vessel that supplies blood to the splenic flexure. However, the positional relationship between the AMCA and inferior mesenteric vein (IMV) has not been evaluated. Herein, we aimed to evaluate the anatomy of the AMCA and the splenic flexure vein (SFV). METHOD Two hundred and five patients with colorectal cancer who underwent enhanced CT preoperatively were enrolled in the present study. The locations of the AMCA and IMV were evaluated, focusing on the positional relationship between the vessels and pancreas - below the pancreas or to the dorsal side of the pancreas. RESULTS The AMCA was observed in 74 (36.1%) patients whereas the SFV was found in 177 (86.3%) patients. The left colic artery (LCA) was the major artery accompanying the SFV in 87 (42.4%) of patients. The AMCA accompanied the SFV in 65 (32.7%) patients. In 15 (7.8%) patients, no artery accompanied the SFV. The origin of the AMCA was located on the dorsal side of the pancreas in 15 (20.3%) of these 74 patients. Similarly, the destination of the IMV was located on the dorsal side of the pancreas in 65 (31.7%) of patients. CONCLUSION The SFV was observed in most patients, and the LCA or AMCA was the common accompanying artery. In some patients these vessels were located on the dorsal side of the pancreas and not below it. Preoperative evaluation of this anatomy may be beneficial for lymph node dissection during left-sided hemicolectomy.

Abstract
AIM The optimal surgical treatment of splenic flexure neoplasm is still not well defined. Extended right hemicolectomy (ERH) and left colic resection (LCR) have been proposed but conclusive evidence concerning postoperative morbidity and oncological results is lacking. The aim of this study was to analyse the short-term outcomes after surgery for splenic flexure cancer with regard to surgical procedure and surgeon's specialty. METHODS This was a multicentre study on patients who underwent surgery for primary colon cancer of the splenic flexure. RESULTS From 2004 to 2015, 324 patients fulfilled the criteria for inclusion into the study; 270 (83.4%) had elective surgery while 54 (16.6%) had emergency resection: 158 (48.8%) underwent ERH and 166 (51.2%) LCR; 176 (54.3%) procedures were performed by colorectal surgeons, 148 (46.7%) by general surgeons. In the ERH group a significantly higher rate of emergency operations was carried out (P = 0.005). After elective surgery, no significant differences between ERH and LCR concerning 30-day mortality (3.3% vs 2.0%) and the need for reoperation (10.6% vs 7.4%) were found. Nodal harvesting was significantly higher in the ERH and colorectal surgeon groups in any clinical scenario. At multivariate analysis, age and smoking habit were predictive of the need for reoperation and major morbidity while the general surgeon group showed a higher risk of anastomotic failure (OR = 1.92; P = 0.168). CONCLUSION We analysed the largest series in literature of curative resections for splenic flexure tumours. The optimal procedure still remains debatable as ERH and LCR appear to achieve comparable short-term outcomes. Surgeon's specialty seems to positively affect patient's outcomes.

Abstract
AIM To evaluate the efficacy and safety of the proposed modified combined approach for laparoscopic splenic flexure mobilization (SFM). MATERIAL AND METHODS A multicenter non-randomized comparative study was conducted. The main group consisted of 12 patients who underwent laparoscopic modified combined SFM from December 2018 to May 2019, the control group consisted of 12 patients who underwent laparoscopic traditional combined SFM from 2013 to 2018. The following aspects were evaluated: total duration of the operation, duration of the SFM, blood loss, rate of conversions, intraoperative complications, postoperative complications, duration of the postoperative period. RESULTS Significant differences were obtained for the average duration of the SFM. The duration of the procedure was calculated during watching a video of operation. The average duration of the SFM in the main group was 37.4±12.2 min, in the control group 59.5±19.1 min (p=0.03). The average blood loss in the main group was 52.5±12.3 ml, in the control group - 115.6±20.7 ml (p=0.02). In the main group there were no intraoperative complications, while in the comparison group 1 case of the spleen damage was noted, requiring conversion, and 1 case of the pancreas damage. These differences are not significant due to the small sample. CONCLUSION The use of the proposed modified combined approach for the laparoscopic SFM significantly reduces the duration of the operation and is accompanied by a decrease in the frequency of intraoperative complications. However, further randomized studies with a larger sample are needed.

Abstract
The splenic flexure is an uncommon location of colorectal cancer, being involved in 2%–3% of cases. The low chance of being engaged in resecting cancer of the splenic flexure can make it difficult for surgeons to build their learning curve and to achieve a reliable experience. As the majority of colectomies are still performed by low-volume surgeons, there is growing agreement that providing local services with adequate surgical education and training could be an effective strategy to improve outcomes and global health. Arming surgeons with simplified and easy-to-learn surgical techniques could be an important step of this strategy. A novel simplified technique for laparoscopic resection of the splenic flexure is presented, which combines laparoscopic mobilisation of the right colon with extracorporeal vascular ligation and bowel anastomosis.

Abstract
BACKGROUND Its relatively low incidence and its surgical complexity mean that a standardized technique for left colectomy has not yet been established for splenic flexure and descending colon cancer (SF-DCC). METHODS Seventy-three patients (robot-assisted left colectomy with complete mesocolectomy [R-LCCM], n = 20; laparoscopic left colectomy with complete mesocolectomy [L-LCCM], n = 53) with SF-DCC were enrolled at the Asan Medical Center (Seoul, Korea). RESULTS R-LCCM conveniently enables dexterous dissection for the multi-directional approaches during left mesocolic mobilization. A conversion to open surgery was required in two patients of the L-LCCM group, but not in the R-LCCM group. A positive circumferential resection margin was exclusively identified in two patients in the L-LCCM group. Mean lymph node harvest was 21 with no difference between the two groups. CONCLUSIONS Although R-LCCM provided few remarkable advantages over L-LCCM, it could be considered as an efficient approach in patients with SF-DCC.

Abstract
INTRODUCTION CT angiography has gained widespread acceptance for preoperative evaluation of blood supply in patients with colorectal cancer. However, there have been few reports that pertain to the splenic flexure, for which surgery is technically difficult. We used preoperative CT angiography and CT colonography to evaluate blood supply to the splenic flexure. METHODS We defined the splenic flexure as the junction of the distal third of the transverse colon and the proximal third of the descending colon. We reviewed 191 cases and considered the descending colon as divided into the proximal third and the distal two-thirds; we then determined which part of the descending colon the left colic artery (LCA) entered. We also considered the transverse colon as divided into the proximal two-thirds and the distal third, and evaluated which part of the transverse colon the left branch of the middle colic artery entered. RESULT We classified blood supply to the splenic flexure into six types, described by the feeder vessels: type 1, the LCA (39.7%); type 2, the left branch of the middle colic artery (17.8%); type 3, the LCA and the left branch of the middle colic artery (9.9%); type 4, the accessory left colic artery (4.1%); type 5, the LCA and the accessory left colic artery (2.6%); and type 6, the marginal artery (25.6%). CONCLUSION We classified blood supply to the splenic flexure into more complex types than previous reports had. Because we dissect the lymph nodes according to the type of blood supply, knowing the type before splenic flexure surgery is crucial.

Abstract
BACKGROUND The cancer of the splenic flexure of the colon is a rare medical entity with severe morbidity because of its insidious onset. METHODS We present the case of a 59-year-old male patient with dull left upper quadrant pain, leukocytosis, and anemia. A splenic abscess described as an air-fluid level with splenocolic fistula was found on CT scan imaging. Surgery was done for splenic pus drainage. He was again admitted 2 months later for intestinal obstruction. RESULTS An exploratory laparotomy showed multiple hard, gray liver nodules as well as a hard mass in the small bowel. Owing to extensive adhesions and a late stage of cancer involvement, the splenic flexure tumor was not resected. A loop transverse colostomy was done and a Coloplast Colostomy bag placed. We also reviewed the literature-linking colon cancer and splenic abscess with specific attention to the carcinoma of the splenic flexure. As the latter invades through the spleen matter, there is the creation of a splenocolic fistula, which allows the migration of normal gut flora into the spleen. This leads to the formation of the splenic abscess. CONCLUSION This is the 13 case report pertaining to invading colonic cancer causing a splenic abscess. Although the treatment for splenic abscesses is shifting from splenectomy to image-guided percutaneous pus drainage, the few reported cases make the proper management of such complication still unclear.
