Abstract
This article discusses the management of isolated metastatic lymph nodes for colon and rectal cancer. There are traditionally significant differences in how certain regions of lymph nodes for colon and rectal cancer are managed in the East and West. This has led to the development of the lateral lymph node dissection for rectal cancer and extended lymphadenectomy techniques for colon cancer. This article will evaluate the literature on these techniques and what the surgical and oncological outcomes are at this time. In addition, colon and rectal cancers can occasionally have isolated distant lymph node metastases. These would traditionally be treated as systemic disease with chemotherapy. There is consideration though that these could be treated as similar to isolated liver or lung metastases which have been shown to be able to be treated surgically with good oncological results. The literature for these isolated distant lymph node metastases will be reviewed and treatment options available will be discussed.

Abstract
With the development of surgical technology, indocyanine green (ICG) fluorescence navigation systems may be useful in various areas of colorectal surgery, including tumor location confirmation, bowel perfusion, ureter identification, and lymph node mapping. This review provides an overview of the current status of ICG-based navigation surgery in colorectal surgery, emphasizing its role in lymphatic flow mapping. This state-of-the-art approach will allow for appropriate oncological surgeries in the field of colorectal cancer and improve the patient's prognosis.

Popescu RC, Leopa N, Iordache IE, Dan C, Moldovan C, Ghioldis AC, Olteanu CM, Kacani A, Cindea I, Popescu I. Prevention of delayed gastric emptying after right colectomy with extended lymphadenectomy: A randomized controlled trial. Medicine (Baltimore) 2023; 102:e35255. [PMID: 37746998 PMCID: PMC10519464 DOI: 10.1097/md.0000000000035255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 07/15/2023] [Accepted: 08/25/2023] [Indexed: 09/26/2023] Open
Abstract
BACKGROUND Delayed gastric emptying sometimes occurs after right colectomy with extended lymphadenectomy. The aim of this randomized controlled trial is to evaluate the effect on delayed gastric emptying after performing a fixation of the stomach to the retrogastric tissue to return the stomach to a physiological position after right colectomy with lymphadenectomy, including gastrocolic lymph nodes dissection for proximal transverse colon cancer. METHODS From January 2015 to December 2020, patients undergoing right colectomy with extensive lymphadenectomy for proximal transverse colon cancer were randomly assigned to either the gastropexy group or the conventional group. In the gastropexy group, the posterior wall of the stomach, at the level of the antrum, was sutured to the retrogastric tissue to prevent the abnormal shape that the gastric antrum acquires together with the duodeno-pancreatic complex, the shape that leads to an obstruction of the antrum region and to the delay in emptying the gastric contents. RESULTS Mean age, sex, comorbidities, and right colectomy procedures were similar in the 2 groups. Delayed gastric emptying developed in twelve patients in the conventional group (38.7%) versus 4 patients (12.1%) in the gastropexy group (P = .014). The total number of complications was higher in the conventional group (14 complications) than in the gastropexy group (7 complications). According to univariate analysis, gastropexy significantly lowered the risk of delayed gastric emptying (P = .014). Overall morbidity was 9.7% in the conventional group versus none in the gastropexy group. Postoperative hospitalization was longer in the conventional group (7.61 ± 3.26 days) than in the gastropexy group (6.24 ± 1.3 days; P = .006). CONCLUSION Gastropexy decreases the occurrence of delayed gastric emptying after right colectomy with extended lymphadenectomy for proximal transverse colon cancer.

Splenic flexure cancer survival: a 25-year experience and implications for complete mesocolic excision (CME) and central vascular ligation (CVL). ANZ J Surg 2023; 93:1861-1869. [PMID: 36978261 DOI: 10.1111/ans.18434] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Revised: 03/08/2023] [Accepted: 03/14/2023] [Indexed: 03/30/2023]
Abstract
BACKGROUND The management of splenic flexure cancers (SFCs) in the era of complete mesocolic excision (CME) and central vascular ligation (CVL) is challenging because of its variable lymphatic drainage. This study aimed to compare survival outcomes for SFCs and non-SFCs, and better understand the clinicopathological characteristics which may define a distinct SFC phenotype. METHODS An observational cohort study at Concord Hospital, Sydney was conducted with patients who underwent resection for colon adenocarcinoma (1995-2019). Clinicopathological data were extracted from a prospective database. Overall survival (OS) and disease-free survival (DFS) estimates and their associations to clinicopathological variables were investigated with Kaplan-Meier and Cox regression analyses. RESULTS Of 2149 patients with colon cancer, 129 (6%) had an SFC. The overall 5-year OS and DFS rates were 63.6% (95% CI 62.5-64.7) and 59.4% (95% CI 58.3-60.5), respectively. SFCs were not associated with OS (P = 0.6) or DFS (P = 0.5). SFCs were more likely to present urgently (P < 0.001) with obstruction (P < 0.001) or perforation (P = 0.03), and more likely to require an open operation (P < 0.001). These characteristics were associated with poorer survival outcomes. No differences were noted between SFCs and non-SFCs with respect to tumour stage (P = 0.3). CONCLUSION SFCs have a distinct phenotype, the individual characteristics of which are associated with poorer survival. However, the survivals of SFCs and non-SFCs are similar, possibly because the most important determinant of outcome, tumour stage, is no different between the groups. This may have implications for the surgical approach to SFCs with respect to standardization of CME and CVL surgery for these cancers.

Abstract
BACKGROUND Complete mesocolic excision (CME) or D3 lymphadenectomy led to survival benefits for locally advanced right colon cancer, but with vague definitions in anatomy and debated surgical hazard in clinic. Aiming to achieve a precise definition of it in anatomy, we proposed laparoscopic right hemicolectomy (D3 + CME) as a novel procedure for colon cancer. However, the surgical and oncological results of this procedure in clinic were uncertain. METHODS We performed a cohort study involving prospective data collected from a single-center in China. Data from all patients who underwent right hemicolectomy between January 2014 and December 2018 were included. We compared the surgical and oncological outcomes between D3 + CME and conventional CME. RESULTS After implementation of exclusion criteria, a total of 442 patients were included. D3 + CME group performed better in lymph nodes harvested (25.0 [17.0, 33.8] vs. 18.0 [14.0, 25.0], P < 0.001) and the proportion of intraoperative blood loss ≥ 50 mL (31.7% vs. 51.8%, P < 0.001); no significant difference was observed in the complication rates between two groups. Kaplan-Meier analysis demonstrated that a better cumulative 5-year disease-free survival (91.3% vs. 82.2%, P = 0.026) and a better cumulative 5-year overall survival (95.2% vs. 86.1%, P = 0.012) were obtained in the D3 + CME group. Multivariate COX regression revealed that D3 + CME was an independent protective factor for disease-free survival (P = 0.026). CONCLUSION D3 + CME could improve surgical and oncological outcomes simultaneously for right colon cancer compared to conventional CME. Large-scale randomized controlled trials were further required to confirm this conclusion, if possible.

Abstract
PURPOSE Extended colectomy is sometimes chosen for treatment of transverse colon cancer (TCC) because of concerns about short- and long-term outcomes. However, there is still a lack of evidence regarding the optimal surgical procedure. METHODS We retrospectively collected and analyzed data of patients who underwent surgical treatment of pathological stage II/III TCC at four hospitals from January 2011 to June 2019. We excluded the patients with TCC located at distal transverse colon, and just evaluated and analyzed proximal and middle third TCC. Inverse probability treatment-weighted propensity score analyses was used to compare short- and long-term outcomes between patients who underwent segmental transverse colectomy (STC) and those who underwent right hemicolectomy (RHC). RESULTS In total, 106 patients were enrolled in this study (STC group, n = 45; RHC group, n = 61). The patients' backgrounds were well balanced after matching. The incidence of major postoperative complications (Clavien-Dindo grade ≥ III) was not significantly different between the STC and RHC groups (4.5% vs. 5.6%, respectively; P = 0.53). The 3-year recurrence-free survival and overall survival rates were not significantly different between the STC and RHC groups (88.2% vs. 81.8%, P = 0.86 and 90.3% vs. 91.9%, P = 0.79, respectively). CONCLUSION RHC has no significant benefits over STC with respect to either short- or long-term outcomes. STC with necessary lymphadenectomy could be an optimal procedure for proximal and middle TCC.

Abstract
PURPOSE Recently, a new certification system called the Endoscopic Surgical Skill Qualification System (ESSQS) has been launched in Japan to improve surgical safety. This study aimed to determine whether ESSQS-qualified surgeons affect the short- and long-term outcomes of laparoscopic right hemicolectomy. METHODS A total of 187 colon cancer patients who underwent laparoscopic right hemicolectomy at Kindai University Hospital between January 2016 and December 2020 were enrolled. These patients were divided into two groups based on surgeries performed by ESSQS-qualified surgeons (QS group) and non-ESSQS-qualified surgeons (NQS group). The short- and long-term outcomes were compared between the two groups before and after propensity score matching (PSM). RESULTS After PSM, 43 patients from each group were included in the matched cohort. In the short-term outcomes, the total operative time was significantly longer in the NQS group than in the QS group (229 vs. 174 min, p < 0.0001). However, there were no significant differences in the two groups regarding blood loss (0 vs. 0 ml, p = 0.7126), conversion (0.0% vs. 7.0%, p = 0.0779), Clavien-Dindo ≥ 2 complications (9.3% vs. 7.0%, p = 0.6933), mortality (2.3% vs. 0.0%, p = 0.3145), and postoperative hospital stay (9 vs. 9 days, p = 0.5357). In the long-term outcomes, there were no significant differences between the two groups in the 3-year overall survival (86.6% vs. 83.0%, p = 0.8361) and recurrence-free survival (61.7% vs. 72.0%, p = 0.3394). CONCLUSION Laparoscopic right hemicolectomy performed by ESSQS-qualified surgeons contributed to shorter operative time. Under the supervision of ESSQS-qualified surgeons, almost equivalent safety and oncological outcomes are expected even in surgeries performed by non-ESSQS-qualified surgeons.

A Narrative Review of the Usefulness of Indocyanine Green Fluorescence Angiography for Perfusion Assessment in Colorectal Surgery. Cancers (Basel) 2022; 14:cancers14225623. [PMID: 36428716 PMCID: PMC9688558 DOI: 10.3390/cancers14225623] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2022] [Revised: 11/12/2022] [Accepted: 11/14/2022] [Indexed: 11/18/2022] Open
Abstract
Anastomotic leakage is one of the most dreaded complications of colorectal surgery and is strongly associated with tissue perfusion. Indocyanine green fluorescence angiography (ICG-FA) using indocyanine green and near-infrared systems is an innovative technique that allows the visualization of anastomotic perfusion. Based on this information on tissue perfusion status, surgeons will be able to clearly identify colorectal segments with good blood flow for safer colorectal anastomosis. The results of several clinical trials indicate that ICG-FA may reduce the risk of AL in colorectal resection; however, the level of evidence is not high, as several other studies have failed to demonstrate a reduction in the risk of AL. Several large-scale RCTs are currently underway, and their results will determine whether ICG-FA is, indeed, useful. The major limitation of the current ICG-FA evaluation method, however, is that it is subjective and based on visual assessment by the surgeon. To complement this, the utility of objective evaluation methods for fluorescence using quantitative parameters is being investigated. Promising results have been reported from several clinical trials, but all trials are preliminary owing to their small sample size and lack of standardized protocols for quantitative evaluation. Therefore, appropriately standardized, high-quality, large-scale studies are warranted.

Pattern of recurrence and survival after D2 right colectomy for cancer: is there place for a routine more extended lymphadenectomy? Updates Surg 2022; 74:1327-1335. [PMID: 35778547 PMCID: PMC9338120 DOI: 10.1007/s13304-022-01317-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Accepted: 06/14/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Conventional Right Colectomy with D2 lymphadenectomy (RC-D2) currently represent the most common surgical treatment of right-sided colon cancer (RCC). However, whether it should be still considered a standard of care, or replaced by a routine more extended D3 lymphadenectomy remains unclear. In the present study, we aim to critically review the patterns of relapse and the survival outcomes obtained from our 11-year experience of RC-D2. METHODS Clinical data of 489 patients who underwent RC-D2 for RCC at two centres, from January 2009 to January 2020, were retrospectively reviewed. Patients with synchronous distant metastases and/or widespread nodal involvement at diagnosis were excluded. Post-operative clinical-pathological characteristics and survival outcomes were evaluated including the pattern of disease relapse. RESULTS We enrolled a total of 400 patients with information follow-up. Postoperative morbidity was 14%. The median follow-up was 62 months. Cancer recurrence was observed in 55 patients (13.8%). Among them, 40 patients (72.7%) developed systemic metastases, and lymph-node involvement was found in 7 cases (12.8%). None developed isolated central lymph-node metastasis (CLM), in the D3 site. The estimated 3- and 5-year relapse-free survival were 86.1% and 84.4%, respectively. The estimated 3- and 5-year cancer-specific OS were 94.5% and 92.2%, respectively. CONCLUSIONS The absence of isolated CLM, as well as the cancer-specific OS reported in our series, support the routine use of RC-D2 for RCC. However, D3 lymphadenectomy may be recommended in selected patients, such as those with pre-operatively known CLM, or with lymph-node metastases close to the origin of the ileocolic vessels.

Multidimensional evaluation of the learning curve for laparoscopic complete mesocolic excision for right colon cancer: a risk-adjusted cumulative summation analysis. Colorectal Dis 2022; 24:577-586. [PMID: 35108445 DOI: 10.1111/codi.16075] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2021] [Revised: 01/17/2022] [Accepted: 01/23/2022] [Indexed: 02/08/2023]
Abstract
AIM Despite the suggested potential benefit of complete mesocolic excision (CME) for right-sided colon cancer (RCC) for patient survival, concerns about its safety and feasibility have contributed to delayed acceptance of the procedure, especially when performed by a minimally invasive approach. Thus, the aim of this work was to evaluate the actual learning curve (LC) of laparoscopic CME for experienced colorectal surgeons. METHOD Prospectively collected data for consecutive patients undergoing laparoscopic CME for RCC between October 2015 and January 2021 at our institution, operated on by experienced surgeons, were analysed. A multidimensional assessment of the LC was performed through cumulative sum (CUSUM) and risk-adjusted (RA) CUSUM analysis. RESULTS Two hundred and two patients operated by on by three surgeons were considered. The CUSUM graphs based on operating time showed one peak of the curve between 17 and 27 cases. The CUSUM graphs based on surgical failure showed one peak of the curve between 20 and 24 cases The RA-CUSUM curve also showed one preeminent peak at 24-33 cases. Based on the CUSUM and RA-CUSUM analyses all the surgeons reached proficiency in 24-33 cases. CONCLUSIONS Our study showed that an experienced minimally invasive colorectal surgeon acquires proficiency in laparoscopic CME for RCC after performing 24-33 cases.

Abstract
AbstractRecent advances in mesenteric anatomy have clarified the shape of the mesentery in adulthood. A key finding is the recognition of mesenteric continuity, which extends from the oesophagogastric junction to the mesorectal level. All abdominal digestive organs develop within, or on, the mesentery and in adulthood remain directly connected to the mesentery. Identification of mesenteric continuity has enabled division of the abdomen into two separate compartments. These are the mesenteric domain (upon which the abdominal digestive system is centered) and the non-mesenteric domain, which comprises the urogenital system, musculoskeletal frame, and great vessels. Given this anatomical endpoint differs significantly from conventional descriptions, a reappraisal of mesenteric developmental anatomy was recently performed. The following narrative review summarizes recent advances in abdominal embryology and mesenteric morphogenesis. It also examines the developmental basis for compartmentalizing the abdomen into two separate domains along mesenteric lines.

Lin L, Yuan SB, Guo H. Does cranial-medial mixed dominant approach have a unique advantage for laparoscopic right hemicolectomy with complete mesocolic excision? World J Gastrointest Surg 2022; 14:221-235.

Abstract
BACKGROUND Complete mesocolic excision (CME) with central vascular ligation (CVL) was proposed by Hohenberger in 2009. The CME principle has gradually become the technical standard for colon cancer surgery. How to achieve CME with CVL in laparoscopic right hemicolectomy (LRH) is controversial, and a unified standard approach is not yet available. In recent years, the authors’ team has integrated the theory of membrane anatomy, tried to combine the cephalic approach with the classic medial approach (MA) for technical optimization, and proposed a cranial-medial mixed dominant approach (CMA).
AIM To explore the feasibility of operational approaches for LRH with CME.
METHODS In this retrospective cohort study, the clinical data of 57 patients with right-sided colon cancer (TNM stage I, II, or III) who underwent LRH with CME from January 2016 to June 2020 were collected and summarized. There were 31 patients in the traditional MA group and 26 in the CMA group.
RESULTS There were no significant differences in baseline data between the two groups. The operation was shorter and the number of lymph nodes dissected was higher in the CMA group than in the MA group, but there was no significant difference in the number of positive lymph nodes, intraoperative blood loss, postoperative exhaust time, feeding time, postoperative hospital stay or postoperative complication incidence.
CONCLUSION Our study shows that the CMA is a safe and feasible procedure for LRH with CME and has a unique advantage.

Abstract
OBJECTIVE The aim of this study to describe a new international dataset for pathology reporting of colorectal cancer surgical specimens, produced under the auspices of the International Collaboration on Cancer Reporting (ICCR). BACKGROUND Quality of pathology reporting and mutual understanding between colorectal surgeon, pathologist and oncologist are vital to patient management. Some pathology parameters are prone to variable interpretation, resulting in differing positions adopted by existing national datasets. METHODS The ICCR, a global alliance of major pathology institutions with links to international cancer organizations, has developed and ratified a rigorous and efficient process for the development of evidence-based, structured datasets for pathology reporting of common cancers. Here we describe the production of a dataset for colorectal cancer resection specimens by a multidisciplinary panel of internationally recognized experts. RESULTS The agreed dataset comprises eighteen core (essential) and seven non-core (recommended) elements identified from a review of current evidence. Areas of contention are addressed, some highly relevant to surgical practice, with the aim of standardizing multidisciplinary discussion. The summation of all core elements is considered to be the minimum reporting standard for individual cases. Commentary is provided, explaining each element's clinical relevance, definitions to be applied where appropriate for the agreed list of value options and the rationale for considering the element as core or non-core. CONCLUSIONS This first internationally agreed dataset for colorectal cancer pathology reporting promotes standardization of pathology reporting and enhanced clinicopathological communication. Widespread adoption will facilitate international comparisons, multinational clinical trials and help to improve the management of colorectal cancer globally.

Abstract
Background Colorectal cancer (CRC) is a significant cause of cancer‐related deaths worldwide and is the third most common cause of cancer deaths in the UK. The status of lymph node metastasis is a key factor for predicting the prognosis of a patient's CRC. Aims This study aimed to analyze the demographics of left-sided colonic and rectal cancers at a single institution. We looked closely at the correlation between patient age and various histological factors. We tried to find any significant difference in lymph node yield (LNY) between laparoscopic surgery (LS) and open surgery (OS). We aimed to identify any statistical correlation between LNY and lymph node positivity (LNP) with other patient, surgical and histopathological features. Methodology This is a retrospective, non-interventional review of consecutive patients who underwent left-sided colonic and rectal cancer resections over a three-year period between 01 April 2018 and 31 March 2021. Descriptive and inferential statistical analyses were used. Chi-squared / Fisher exact test was used on a categorical scale between two or more groups and non-parametric setting for qualitative data analysis. Results A total of 102 patients were included in the study. No statistical correlation was found between the age of the patient with the LNY, LNP, location of the tumor, type, and urgency of the operation. LNY ranged between one and 43 nodes (median (interquartile range (IQR)) 17, 8). There was no statistically significant difference in LNY between laparoscopic surgery (LS) and open surgery (OS) (p=0.1449). Significant statistical correlation was identified between LNP and completeness of resection (CoR) (p=0.039), vascular invasion (VI) (p<0.001), perineural invasion (PI) (p<0.001), and circumferential resectional margin involvement (CRMI) (p=0.039). Discussion LNY and LNP are important prognostic indices in colorectal cancer. Patient age, tumor location, the urgency of surgery, and consultant experience did not significantly impact the LNY. Our study showed a positive correlation between LNP and CRMI, VI and PI comparable to literature. Contrary to other studies, we found no statistical significance between LS vs. OS and LNY. Whether 12 nodes per patient is an appropriate level remains controversial.

Abstract
AIM The aim of this study is to demonstrate our video training tool developed to teach and standardize complete mesocolic excision (CME) for right-sided colon cancer and also to present our long-term oncological outcomes. METHOD Educational narrative videos were produced to demonstrate the technical steps of CME. First, a three-dimensional animation video was prepared. Then cadaveric dissections were recorded in a step-by-step fashion, following the sequences of open and minimally invasive surgery. These were followed by videos of real-life demonstrations of surgical procedures, enhanced by superimposed animations of key anatomical structures. In order to demonstrate the impact of this training module on outcomes of patients undergoing CME, we retrospectively queried data from before (2005-2010) and after (2011-2019) implementation of standardized CME in our practice. RESULTS A total of 180 consecutive patients underwent right hemicolectomy between 2005 and 2019. Fifty-four patients underwent surgery before and 126 patients after CME principles were elaborated and standardized. Of those patients who had surgery after the training module, 58 (46%) underwent open surgery and 68 (54%) underwent laparoscopic colectomy. Demographics, perioperative parameters and morbidity were comparable between the groups. The 5-year overall and disease-free survival rates were significantly improved after implementation of CME training (p = 0.059 and p = 0.041, respectively). Also, 5-year overall and disease-free survival rates for all patients were considerably better than our reported national outcomes. CONCLUSION Our comprehensive step-by-step training video module for the CME technique demonstrates surgical anatomical planes and important vascular structures and variations. The video also helps standardization of the CME technique and should contribute to improved histopathological and oncological outcomes.

Abstract
PURPOSE On a national level, the minimally invasive approach is widely adopted in Denmark. The adoption of robotic colorectal surgery is increasing; however, the advantage of a robotic approach in right colectomy is still uncertain. The purpose of this study was to compare robotic right colectomy with laparoscopic right colectomy on a national level. METHODS This was a nationwide database study based on data from the Danish Colorectal Cancer Group database. Patients from all colorectal centers in Denmark in the period 2014-2018 treated with curative intend in an elective setting with either robotic or laparoscopic right colectomy were identified. Propensity score matching was performed to adjust for confounding, and the groups were compared on demographics, disease characteristics, operative data, and postoperative and pathology outcomes. Reporting was done in accordance with the STROBE statement. RESULTS In total, 4002 patients were available for analysis. Propensity score matching in ratio 2:1 identified 718 laparoscopic and 359 robotic cases. After matching, we found a higher lymph node yield in the robotic group compared to the laparoscopic group, (32.5 vs. 28.4, P < 0.001), while radicality, plane of dissection, and pathological disease stages showed no differences. There were no statistical differences in morbidity and mortality. Intracorporeal anastomosis (23.7% vs. 4.5%, P < 0.001) was more commonly performed with a robotic approach. CONCLUSIONS Robotic approach was associated with a significant higher lymph node yield and with similar postoperative morbidity compared to a laparoscopic approach for right colectomy.

Abstract
Since the 19th century, appropriate lymphadenectomy has been considered a cornerstone of oncologic surgery and one of the most important prognostic factors. This approach can be applied to any surgery for gastrointestinal cancer. During surgery for colon and rectal cancer, an adequate portion of the mesentery is removed together with the segment of bowel affected by the disease. The adequate number of lymph nodes to be removed is standardized and reported by several guidelines. It is mandatory to determine the appropriate extent of lymphadenectomy and to balance its oncological benefits with the increased morbidity associated with its execution in cancer patients. Our review focuses on the concept of “complete mesenteric excision (CME) with central vascular ligation (CVL),” a radical lymphadenectomy for colorectal cancer that has gained increasing interest in recent years. The aim of this study was to evaluate the evolution of this approach over the years, its potential oncologic benefits and potential risks, and the improvements offered by laparoscopic techniques. Theoretical advantages of CME are improved local-relapse rates due to complete removal of the intact mesocolic fascia and improved distance recurrence rates due to ligation of vessels at their origin (CVL) which guarantees removal of a larger number of lymph nodes. The development and worldwide diffusion of laparoscopic techniques minimized postoperative trauma in oncologic surgery, providing the same oncologic results as open surgery. This has been widely applied to colorectal cancer surgery; however, CME entails a technical complexity that can limit its wide minimally-invasive application. This review analyzes results of these procedures in terms of oncological outcomes, technical feasibility and complexity, especially within the context of minimally invasive surgery.

Right-side colectomy with complete mesocolic excision vs conventional right-side colectomy in the treatment of colon cancer: a systematic review and meta-analysis. Int J Colorectal Dis 2021; 36:1885-1904. [PMID: 33983451 DOI: 10.1007/s00384-021-03951-5] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 05/04/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND This meta-analysis aims to investigate the role of complete mesocolic excision (CME) in the treatment of right-side colon cancer when compared with standard right-side hemicolectomy, focusing on oncological outcomes, mortality and morbidity rates. MATERIALS AND METHODS A systematic literature search was performed on MEDLINE and EMBASE archives, including studies on CME in right-side colon cancer. Primary outcomes were five-year disease-free survival and five-year overall survival. Secondary outcomes investigated were mortality and morbidity rates, intraoperative blood loss, anastomotic leakage, postoperative ileus, day of postoperative flatus, pulmonary infection, duration of hospital stay and number of lymph nodes harvested. RESULTS Seventeen studies have been included in this meta-analysis for a total of 3918 patients. The five-year disease-free survival (DFS) and overall survival (OS) results improved in the CME group with respect to conventional right-side colectomy with an OR 1.88 (95% CI 1.02-3.45) and OR 2.77 (95% CI 1.33-5.74), respectively. The incidence of mortality and morbidity was comparable between the two groups. Moreover, conventional surgery time was faster than CME (MD 33.69 min, 95% CI 12.79-54.59), while no significant differences were reported in mean blood loss and hospital stay. Furthermore, the CME group showed a higher mean number of harvested lymph nodes (MD 7.08 lymph nodes 95% CI 4.90-9.27). CONCLUSION Complete mesocolic excision of the right-side colectomy improves oncological outcomes without increasing mortality and morbidity rates compared to standard right-side hemicolectomy. CME should therefore be routinely performed in the treatment of right-side colon cancer.

Abstract
In the nineteenth century the idea of a correct surgical approach in oncologic surgery moved towards a good lymphadenectomy. In colon cancer the segment is removed with adjacent mesentery, in gastric cancer or pancreatic cancer a good oncologic resection is obtained with adequate lymphadenectomy. Many guidelines propose a minimal lymph node count that the surgeon must obtain. Therefore, it is essential to understand the adequate extent of lymphadenectomy to be performed in cancer surgery. In this review of the current literature, the focus is on "central vascular ligation", understood as radical lymphadenectomy in upper and lower gastrointestinal cancer, the evolution of this approach during the years and the improvement of laparoscopic techniques. For what concerns laparoscopic surgery, the main goal is to minimize post-operative trauma introducing the "less is more" concept whilst preserving attention for oncological outcomes. This review will demonstrate the importance of a scientifically based standardization of oncologic gastrointestinal surgery, especially in relation to the expansion of minimally invasive surgery and underlines the importance to further investigate through new randomized trials the role of extended lymphadenectomy in the new era of a multimodal approach, and most importantly, an era where minimally invasive techniques and the idea of "less is more" are becoming the standard thought for the surgical approach.

Abstract
AIM Complete mesocolic excision (CME) lacks consistent data advocating operative superiority compared to conventional surgery for colon cancer. We performed a systematic review and meta-analysis, analysing population characteristics and perioperative, pathological and oncological outcomes. METHODS D3 extended lymphadenectomy dissection was considered comparable to CME, and D2 and D1 dissection to be comparable to conventional surgery. Outcomes reviewed included lymph node yield, R1 resection, overall complications, overall survival and disease-free survival. RESULTS In all, 3039 citations were identified; 148 studies underwent full-text reviews and 31 matched inclusion criteria: total cohort 26 640 patients (13 830 CME/D3 vs. 12 810 conventional). Overall 3- and 5-year survival was higher in the CME/D3 group compared with conventional surgery: relative risk (RR) 0.69 (95% CI 0.51-0.93, P = 0.016) and RR 0.78 (95% CI 0.64-0.95, P = 0.011) respectively. Five-year disease-free survival also demonstrated CME/D3 superiority (RR 0.67, 95% CI 0.52-0.86, P < 0.001), with similar findings at 1 and 3 years. There were no statistically significant differences between the CME/D3 and conventional group in overall complications (RR 1.06, 95% CI 0.97-1.14, P = 0.483) or anastomotic leak (RR 1.02, 95% CI 0.81-1.29, P = 0.647). CONCLUSIONS Meta-analysis suggests CME/D3 may have a better overall and disease-free survival compared to conventional surgery, with no difference in perioperative complications. Quality of evidence regarding survival is low, and randomized control trials are required to strengthen the evidence base.

Abstract
BACKGROUND Colorectal cancer (CRC), the third most common cancer globally, caused 881,000 cancer deaths in 2018. Toll-like receptors (TLRs), the primary sensors of pathogen-associated molecular patterns and damage-associated molecular patterns, activate innate and adaptive immune systems and participate in the development of an inflammatory tumor microenvironment. We aimed to explore the prognostic value of TLR3, TLR5, TLR7, and TLR9 tissue expressions in CRC patients. METHODS Using immunohistochemistry, we analyzed tissue microarray samples from 825 CRC patients who underwent surgery between 1982 and 2002 at the Department of Surgery, Helsinki University Hospital, Finland. After analyzing a pilot series of 205 tissue samples, we included only TLR5 and TLR7 in the remainder of the patient series. We evaluated the associations between TLR5 and TLR7 tissue expressions, clinicopathologic variables, and survival. Using the Kaplan-Meier method, we generated survival curves, determining significance using the log-rank test. Univariate and multivariate survival analyses relied on the Cox proportional hazards model. RESULTS The 5-year disease-specific survival was 55.9% among TLR5-negative (95% confidence interval [CI] 50.6-61.2%) and 61.9% (95% CI 56.6-67.2%; p = 0.011, log-rank test) among TLR5-positive patients. In the Cox multivariate survival analysis adjusted for age, sex, stage, location, and grade, positive TLR5 immunoexpression (hazard ratio [HR] 0.74; 95% CI 0.59-0.92; p = 0.007) served as an independent positive prognostic factor. TLR7 immunoexpression exhibited no prognostic value in the survival analysis across the entire cohort (HR 0.97; 95% CI 0.78-1.20; p = 0.754) nor in subgroup analyses. CONCLUSIONS We show for the first time that a high TLR5 tumor tissue expression associates with a better prognosis in CRC patients.

Laparoscopic complete mesocolic excision versus conventional resection for right-sided colon cancer: a propensity score matching analysis of short-term outcomes. Surg Endosc 2021; 36:3049-3058. [PMID: 34129088 DOI: 10.1007/s00464-021-08601-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 06/06/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Complete mesocolic excision (CME) for right-sided colon cancer (RCC) is a demanding operation, especially when performed laparoscopically. The potential impact of CME in increasing postoperative complications is still unclear. The aim of our study was to evaluate the safety and feasibility of laparoscopic CME compared with laparoscopic non-complete mesocolic excision (NCME) during colectomy for RCC. METHODS Data from a prospectively collected database of patients who underwent laparoscopic right and extended right colectomy at our institution between January 2008 and February 2020 were retrieved and analyzed. Short-term outcomes of patients undergoing CME and NCME were compared. A 1:1 propensity score matching (PSM) was used to balance baseline characteristics between groups. RESULTS A total of 663 consecutive patients underwent resection of RCC in the study period. Among these, 500 met the inclusion criteria and after PSM a total of 372 patients were correctly matched, 186 in each group. A similar rate of overall postoperative complications was found between the CME and NCME groups (21.5% and 18.3%, p = 0.436). No difference was found in terms of conversion rate, severe complications, reoperations, readmissions, and mortality. The median number of harvested lymph nodes was higher in the CME group (22 versus 19, p = 0.003), with a lower rate of inadequate sampling (7.0% and 15.1%, p = 0.013). CONCLUSION Laparoscopic CME for RCC is technically feasible and safe. It does not seem to be associated with a higher rate of complications or mortality compared with the "traditional" approach, but it allows better nodal sampling.

Right hemicolectomy with complete mesocolic excision is safe, leads to an increased lymph node yield and to increased survival: results of a systematic review and meta-analysis. Tech Coloproctol 2021; 25:1099-1113. [PMID: 34120270 PMCID: PMC8419145 DOI: 10.1007/s10151-021-02471-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Accepted: 05/30/2021] [Indexed: 01/04/2023]
Abstract
BACKGROUND The introduction of complete mesocolic excision (CME) for right colon cancer has raised an important discussion in relation to the extent of colic and mesenteric resection, and the impact this may have on lymph node yield. As uncertainty remains regarding the usefulness of and indications for right hemicolectomy with CME and the benefits of CME compared with a traditional approach, the purpose of this meta-analysis is to compare the two procedures in terms of safety, lymph node yield and oncological outcome. METHODS We performed a systematic review of the literature from 2009 up to March 15th, 2020 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two hundred eighty-one publications were evaluated, and 17 met the inclusion criteria and were included. Primary endpoints analysed were anastomotic leak rate, blood loss, number of harvested lymph nodes, 3- and 5-year oncologic outcomes. Secondary outcomes were operating time, conversion, intraoperative complications, reoperation rate, overall and Clavien-Dindo grade 3-4 postoperative complications. RESULTS In terms of safety, right hemicolectomy with CME is not inferior to the standard procedure when comparing rates of anastomotic leak (RR 0.82, 95% CI 0.38-1.79), blood loss (MD -32.48, 95% CI -98.54 to -33.58), overall postoperative complications (RR 0.82, 95% CI 0.67-1.00), Clavien-Dindo grade III-IV postoperative complications (RR 1.36, 95% CI 0.82-2.28) and reoperation rate (RR 0.65, 95% CI 0.26-1.75). Traditional surgery is associated with a shorter operating time (MD 16.43, 95% CI 4.27-28.60) and lower conversion from laparoscopic to open approach (RR 1.72, 95% CI 1.00-2.96). In terms of oncologic outcomes, right hemicolectomy with CME leads to a higher lymph node yield than traditional surgery (MD 7.05, 95% CI 4.06-10.04). Results of statistical analysis comparing 3-year overall survival and 5-year disease-free survival were better in the CME group, RR 0.42, 95% CI 0.27-0.66 and RR 0.36, 95% CI 0.17-0.56, respectively. CONCLUSIONS Right hemicolectomy with CME is not inferior to traditional surgery in terms of safety and has a greater lymph node yield when compared with traditional surgery. Moreover, right-sided CME is associated with better overall and disease-free survival.

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.

Abstract
BACKGROUND Complete mesocolic excision (CME) of colon cancer with extended lymphadenectomy was suggested to improve radical resection of colon cancer. This comprehensive review aimed to assess the current literature for the outcomes of CME of colon cancer through an appraisal of the findings of published systematic reviews and meta-analyses. METHODS A systematic literature review searching for the studies that assessed the outcome of CME of colon cancer was conducted. Electronic databases were queried from 2009 through November 2020. The main objectives of this review were to illustrate the technical aspects and outcome of CME and to summarize the findings of the published systematic reviews. RESULTS Thirteen systematic reviews were retrieved. All reviews found CME to provide longer bowel, larger area of mesentery resected, and more lymph nodes (LNs) retrieved than standard colectomy. All systematic reviews except two found similar complication rates between CME and standard colectomy. Four systematic reviews documented the survival benefit of CME in regards to improved overall and disease-free survival. Using the laparoscopic approach for CME did not compromise the oncologic outcomes of the procedures, yet was associated with less intraoperative blood loss, faster recovery, and potential survival benefits. CONCLUSIONS CME is associated with better specimen quality, more LNs clearance, and potential survival benefits compared to standard colectomy. However, the lack of robust data from well-designed multicenter randomized trials may prevent drawing firm conclusions on the oncologic benefits of CME. Further high-quality studies are needed before recommending CME as the standard of care for colon cancer.

Abstract
Objective This study aimed to explore the pathological characteristics of lymph nodes around inferior mesenteric artery in rectal cancer and its risk factors and its impact on tumor staging. Methods 485 rectal cancer patients underwent proctectomy surgery were collected in this study. Clinical features of patients, including gender, age, BMI, tumor size, pathological type, differentiation, nerve invasion, lymph nodes, tumor marker, and pathological examinations, were analyzed. Results A total of 485 cases were included in this study. There were 29 cases with IMA-LN metastasis; the metastasis rate was 5.98% (29/485). Positive IMA-LNs were associated with distance from anal verge, CEA, pathological type, differentiation, nerve invasion, T stage, and N stage. Multivariate analysis showed that distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. Conclusion Distance from anal verge, CEA level, differentiation, and T stage were independent risk factors for positive IMA-LNs. No skip metastasis occurred in IMA-LNs. We should choose the appropriate surgical methods to achieve better oncological results and reduce the incidence of postoperative complications.

Abstract
Colorectal cancers comprise a large percentage of tumors worldwide, and transverse colon cancer (TCC) is defined as tumors located between hepatic and splenic flexures. Due to the anatomy and embryology complexity, and lack of large randomized controlled trials, it is a challenge to standardize TCC surgery. In this study, the current situation of transverse/extended colectomy, robotic/ laparoscopic/open surgery and complete mesocolic excision (CME) concept in TCC operations is discussed and a heatmap is conducted to show the evidence level and gap. In summary, transverse colectomy challenges the dogma of traditional extended colectomy, with similar oncological and prognostic outcomes. Compared with conventional open resection, laparoscopic and robotic surgery plays a more important role in both transverse colectomy and extended colectomy. The CME concept may contribute to the radical resection of TCC and adequate harvested lymph nodes. According to published studies, laparoscopic or robotic transverse colectomy based on the CME concept was the appropriate surgical procedure for TCC patients.

Abstract
PURPOSE Complete mesocolic excision (CME) has introduced a promising surgical approach for treatment of right colon cancer. However, benefits of CME are still a matter of debate. We conducted a systematic review and meta-analysis to assess safety and long-term outcomes of CME versus conventional right hemicolectomy (CRH). METHODS We systematically searched MEDLINE, the Cochrane Database of Systematic Reviews, Scopus, Web of Science, and Embase for retrieving studies comparing CME with CRH in right colon cancer. After data extraction from the included studies, meta-analysis was performed to compare postoperative complications, anastomotic leakage, 30-day mortality, number of lymph node yield, disease-free survival (DFS), and overall survival (OS). RESULTS Eight studies met the inclusion criteria with a total of 1871 patients enrolled. No difference was observed in postoperative complications (OR 1.13, 95% CI 0.88-1.47, p = 0.34). CME was associated with significantly higher number of lymph nodes retrieved (MD 9.17, CI 4.67-13.68, p < 0.001). CME also improved 3-year OS (OR 1.57, 95% CI 1.17-2.11, p = 0.003), 5-year OS (OR 1.41, 95% CI 1.06-1.89, p = 0.02), and 5-year DFS (OR 1.99, 95% CI 1.29-3.07, p = 0.002). A sub-group analysis for patients with stage III colon cancer showed no significant impact of CME on 3-year and 5-year OS (OR 2.47, 95% CI 0.86-7.06, p = 0.09; OR 1.23, 95% CI 0.78-1.94, p = 0.38). CONCLUSION Although with limited evidence, CME shows similar postoperative complication rates and an improved survival outcome compared with CRH.

Abstract
Purpose Laparoscopic complete mesocolic excision (CME) right colectomy is a technically demanding procedure infrequently employed in Western centers. This retrospective cohort study aims to analyze the safety of laparoscopic CME colectomy compared to standard colectomy for right-sided colon cancer in a Western series. Methods Prospectively collected data from 60 patients who underwent laparoscopic CME right colectomy were compared to the ones of 55 patients who underwent laparoscopic standard right colectomy. Results No differences in clinical characteristics were observed between the CME and standard right colectomy groups. No differences were demonstrated in terms of blood loss (P = 0.060), intraoperative complications (P = 1), conversion rate (P = 0.102), and operative time (P = 0.473). No deaths were observed in either group, while complication rate was 40.0% in the CME and 49.1% in the standard group (P = 0.353). Severe complications occurred in 10.0% vs. 9.1% (P = 0.842), redo surgery in 5.0% vs. 7.3% (P = 0.708), and unplanned readmission in 5.0% vs. 5.5% (P = 1) after CME and standard colectomy, respectively. A significant difference in favor of CME was observed in the total length of specimen (P < 0.001), proximal (P = 0.018), and distal margins (P = 0.037). The number of lymph nodes harvested was significantly higher in the CME group (27 vs. 22, P = 0.037). Conclusion In Western series, where patients have less favorable clinical characteristics, laparoscopic CME allows to obtain better quality surgical specimens and comparable short-term outcomes compared to standard right colectomy.

Abstract
BACKGROUND Minimally invasive right colectomy is increasingly performed as standard treatment for diseases of right colon. Complete mesocolic excision has been introduced for cancer treatment to improve oncological results. Both standard and complete mesocolic excision techniques are associated with intraoperative complications. The purpose of this study was to analyse incidence and management of intraoperative complications in patients who underwent laparoscopic right colectomy with complete mesocolic excision in a single institution. METHODS This is a retrospective study conducted in a single Italian centre from April 2017 to October 2020. Data of non-metastatic cancer patients who underwent laparoscopic right colectomy were collected to analyse onset of intraoperative complications, their management and rate of conversion to open surgery. RESULTS A total of 92 patients were included in this study. The 1.09% of patients were converted to open surgery due to adhesions and bowel occlusion. The 5.43% of patients had intraoperative complications: bleeding from Henle's trunk, pre-pancreatic plane and ileocolic artery stump account for 3.26%, gonadal vessel injury for 1.09% and bowel lesion for 1.09%. CONCLUSIONS Despite the limits of this study, it shows that bleeding is one of the most frequent complications in laparoscopic right colectomy. Bleeding, occlusion and adhesions are most common reasons for conversion to open surgery.

Abstract
Background: Colectomies performed according to complete mesocolic excision with central vascular ligation (CME-CVL) principles have been associated with enhanced oncologic outcomes. Nonetheless, laparoscopic CME-CVL right hemicolectomy has not been widely adopted. We aimed to compare the perioperative and pathology outcomes of laparoscopic and open CME-CVL right hemicolectomy. Materials and Methods: We compared data from a prospectively collected database regarding patients who underwent either laparoscopic or open CME-CVL right hemicolectomy for nonmetastatic right colon cancer in a University Hospital, between January 2012 and December 2018. Results: A total of 130 consecutive patients were included in the study. Of them, 73 patients underwent laparoscopic and 57 patients open right colectomy, following the CME-CVL principles. The laparoscopic approach was associated with less hospital stay (6.6 versus 9.1 days; P < .001) and septic complications (P = .046), at a cost of an increased operative time (180 versus 125.1 minutes; P < .001). Patients treated with either open or laparoscopic approach presented similar outcomes regarding pathology endpoints. In fact, both groups demonstrated similar R0 resection rate (P = .202), number of harvested and positive lymph nodes (P = .751 and P = .734, respectively), number of harvested lymph nodes at the level of D1 and D2 lymph node dissection (P > .05), rate of vascular (P = .501), and perineural infiltration (P = .956). Furthermore, no difference was found regarding the rate of intact mesocolic plane (P = .799), along with the tumor diameter (P = .154) and the length of specimen (P = .163). Conclusion: Laparoscopic CME-CVL right hemicolectomy appears to offer certain advantages in short-term outcomes compared to open procedure. Pathology outcomes did not differ between the two approaches. Future studies should further evaluate their long-term outcomes.

Abstract
BACKGROUND Surgical treatment for transverse colon cancer involves either extended colectomy or segmental resection, depending on the location of the tumor and surgeon perspective. However, the oncological safety of segmental resection has not yet been established in large cohort studies. OBJECTIVE This study aims to compare segmental resection versus extended colectomy for transverse colon cancer in terms of oncological outcomes. DESIGN This was a retrospective cohort study. SETTINGS This study was conducted using a nationwide cohort. PATIENTS A total of 66,062 patients who underwent colectomy with curative intent for transverse stage I to III adenocarcinoma were identified in the National Cancer Database (2004-2015). MAIN OUTCOME MEASURES Patients were divided in 2 groups based on the type of surgery received (extended versus segmental resection). The primary outcome was overall survival. Secondary outcomes were 30- and 90-day mortality, length of hospital stay, and readmission rate within 30 days of surgical discharge. RESULTS Extended colectomy was performed in 44,417 (67.2%) patients, whereas 21,645 (32.8%) patients underwent segmental resection. Extended colectomy was associated with lower survival at multivariate analysis (HR, 1.07; 95% CI, 1.04-1.10; p < 0.001). The subgroup analysis showed that extended resection was independently associated with poorer survival in mid transverse colon cancers (HR, 1.08; 95% CI, 1.04-1.12; p < 0.001) and in stage III tumors (HR, 1.11; 95% CI, 1.04-1.18; p < 0.001). The number of at least 12 harvested lymph nodes was an independent predictor of improved survival in both overall and subgroup analyses. LIMITATIONS This study was limited by its retrospective design. CONCLUSION Extended colectomy was not associated with a survival advantage compared with segmental resection. On the contrary, extended colectomy was associated with slightly poorer survival in mid transverse cancers and locally advanced tumors. Segmental resection was found to be safe when appropriate margins and adequate lymph node harvest were achieved. See Video Abstract at http://links.lww.com/DCR/B454. ABORDAJE QUIRRGICO DEL CNCER DE COLON TRANSVERSO ANLISIS DE LA PRCTICA ACTUAL Y LOS RESULTADOS ONCOLGICOS UTILIZANDO LA BASE DE DATOS NACIONAL DE CNCER ANTECEDENTES:El tratamiento quirúrgico para el cáncer de colon transverso implica colectomía extendida o resección segmentaria, según la ubicación del tumor y la perspectiva del cirujano. Sin embargo, la seguridad oncológica de la resección segmentaria aún no se ha establecido en estudios de cohortes grandes.OBJETIVO:Este estudio tiene como objetivo comparar la resección segmentaria versus la colectomía extendida para el cáncer de colon transverso en términos de resultados oncológicos.DISEÑO:Este fue un estudio de cohorte retrospectivo.ESCENARIO:Este estudio se realizó utilizando una cohorte a nivel nacional.PACIENTES:Un total de 66,062 pacientes que se sometieron a colectomía con intención curativa por adenocarcinoma de colon transverso en estadio I-III fueron identificados en la Base de Datos Nacional del Cáncer (2004-2015).PRINCIPALES MEDIDAS DE RESULTADO:Los pacientes se dividieron en dos grupos según el tipo de cirugía recibida (resección extendida versus resección segmentaria). El resultado primario fue la supervivencia global. Los resultados secundarios fueron la mortalidad a los 30 y 90 días, la duración de la estancia hospitalaria y la tasa de reingreso dentro de los 30 días posteriores al alta quirúrgica.RESULTADOS:Se realizó colectomía extendida en 44,417 (67.2%) casos, mientras que 21,645 (32.8%) pacientes fueron sometidos a resección segmentaria. La colectomía extendida se asoció con una menor supervivencia en el análisis multivariado (HR 1.07 IC 95% 1.04-1.10; p <0.001). El análisis de subgrupos mostró que la resección extendida se asoció de forma independiente con una menor supervivencia en los cánceres de colon transverso medio (HR 1.08 IC 95% 1.04-1.12; p <0.001) y en tumores en estadio III (HR 1.11 IC 95% 1.04-1.18; p <0.001). Un número de al menos 12 ganglios linfáticos cosechados fue un predictor independiente de una mejor supervivencia en los análisis general y de subgrupos.LIMITACIONES:Este estudio estuvo limitado por su diseño retrospectivo.CONCLUSIÓN:La colectomía extendida no se asoció con una ventaja de supervivencia en comparación con la resección segmentaria. Por el contrario, la colectomía extendida se asoció con una supervivencia levemente menor en cánceres de colon transverso medio y tumores localmente avanzados. Se encontró que la resección segmentaria es segura cuando se logran los márgenes apropiados y la cosecha adecuada de ganglios linfáticos. Consulte Video Resumen en http://links.lww.com/DCR/B454.

Abstract
BACKGROUND D3-Lymphadenectomy, together with complete mesocolic excision (CME), were introduced to provide oncological results after right colon cancer. The aim of this systematic review with meta-analysis was to assess the short and long-term outcomes of right-sided hemicolectomy with CME + D3 as compared with classic right hemicolectomy. Secondary aims included the prevalence of D3-metastasis and skip metastasis when performing CME + D3. MATERIAL AND METHODS A systematic review with meta-analysis was conducted, according to PRISMA methodology. RESULTS 29 studies were enrolled (2592 patients). No differences were accounted in morbidity variables associated with the measured techniques. CME + D3 was significantly associated with a greater distance between the tumour and the closest vascular tie, a longer colonic resection, a wider resection of mesentery and an increased number of harvested lymph nodes. Regarding to long-terms outcomes, we found a significant decrease in local recurrence in patients undergoing CME + D3 (HR:0.17) and a significant improvement in 3-year and 5-year overall survival rates (HR:0.53 vs. HR:0.57, respectively), as well as an improving survival in patients with stage II and III disease. Overall prevalence of patients with lymphatic metastases in D3-territory was of 8.6% and 2.2% of skip metastases. CONCLUSIONS CME + D3 is a feasible surgical procedure that allows to obtain specimens with higher quality oncological resection, without greater associated morbidity, thus improving survival in patients with stage II and III right colon cancer.

Recurrence Risk after Radical Colorectal Cancer Surgery-Less Than before, But How High Is It? Cancers (Basel) 2020; 12:cancers12113308. [PMID: 33182510 PMCID: PMC7696064 DOI: 10.3390/cancers12113308] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 10/27/2020] [Accepted: 11/06/2020] [Indexed: 02/06/2023] Open
Abstract
Simple Summary Evidence indicates that recurrence risk after colon cancer today is less than it was when trials performed decades ago showed that adjuvant chemotherapy reduces the risk and prolong disease-free and overall survival. After rectal cancer surgery, local recurrence rates have decreased but it is unclear if systemic recurrences have. After a systematic review of available literature reporting recurrence risks after curative colorectal cancer surgery we report that the risks are lower today than they were in the past and that this risk reduction is not solely ascribed to the use of adjuvant therapy. Adjuvant therapy always means overtreatment of many patients, already cured by the surgery. Fewer recurrences mean that progress in the care of these patients has happened but also that the present guidelines giving recommendations based upon old data must be adjusted. The relative gains from adding chemotherapy are not altered, but the absolute number of patients gaining is less. Abstract Adjuvant chemotherapy aims at eradicating tumour cells sometimes present after radical surgery for a colorectal cancer (CRC) and thereby diminish the recurrence rate and prolong time to recurrence (TTR). Remaining tumour cells will lead to recurrent disease that is usually fatal. Adjuvant therapy is administered based upon the estimated recurrence risk, which in turn defines the need for this treatment. This systematic overview aims at describing whether the need has decreased since trials showing that adjuvant chemotherapy provides benefits in colon cancer were performed decades ago. Thanks to other improvements than the administration of adjuvant chemotherapy, such as better staging, improved surgery, the use of radiotherapy and more careful pathology, recurrence risks have decreased. Methodological difficulties including intertrial comparisons decades apart and the present selective use of adjuvant therapy prevent an accurate estimate of the magnitude of the decreased need. Furthermore, most trials do not report recurrence rates or TTR, only disease-free and overall survival (DFS/OS). Fewer colon cancer patients, particularly in stage II but also in stage III, today display a sufficient need for adjuvant treatment considering the burden of treatment, especially when oxaliplatin is added. In rectal cancer, neo-adjuvant treatment will be increasingly used, diminishing the need for adjuvant treatment.

Abstract
The treatment of colon cancer has had numerous recent advances, in terms of surgical approach, adjuvant therapies, and more. In this review, the authors examine randomized clinical trials comparing open surgery to laparoscopic surgery (including total mesocolic excision), and also examine the role of robotic surgery. Novel surgical techniques including the no-touch technique, side-to-side anastomosis, suture technique, complete mesocolic excision (CME) with central vascular ligation (CVL), and natural orifice transluminal endoscopic surgery (NOTES) are outlined. The role of placing endoscopic self-expandable metal stents (SEMS) for colonic obstruction is compared and contrasted with the surgical approach, and the effect that the anti-VEGF inhibitor bevacizumab may have on this side effect profile is further explored. The role of the resection of the primary tumor in the setting of metastatic disease is examined with respect to survival benefit. Pathways of perioperative care which can accelerate post-surgical recovery, including enhanced recovery after surgery (ERAS) are examined. The role of adjuvant chemotherapy in patients with high-risk stage II and patients with stage III disease is examined, along with the role on circulating tumor DNA (ctDNA) as well as with the biologic targeted agents cetuximab and bevacizumab. Lastly, the authors detail the postoperative surveillance schedules after surgical resection with respect to survival outcomes.

Abstract
Background and Objectives: Literature demonstrates that colorectal cancer is nowadays one of the most common malignancies. Laparoscopy and robotic surgery are progressively gaining popularity in the treatment of colorectal tumors. Complete mesocolic excision and central vascular ligation have been widely adopted with encouraging results in terms of an improvement of overall survival, but some studies in the literature seem to demonstrate a higher morbidity rate. Methods: We conducted a retrospective study from 01/01/2010 to 30/04/2019 on a series of 250 patients, 155 males (62%) and 95 females (38%) who underwent right colectomy with minimally invasive approach, complete mesocolic excision, central vascular ligation, and intracorporeal anastomosis. Results: No perioperative mortality occurred. Postoperative morbidity rate was 6%, including 10 cases of anastomotic leak (5%). Conversion rate was 2.5%. Mean hospital stay was 6 days (range, 4–25 days). Mean operative time was 70 minutes (range, 50–130 minutes). No cases of duodenal or pancreatic damages, no chronic pain or diarrhea, and no severe alteration of bowel function were recorded. We observed only 3 cases of transient delayed gastric emptying. Conclusions: Laparoscopic right colectomy with complete mesocolic excision, central vascular ligation and intracorporeal anastomosis leads to encouraging oncological mid- and long-term outcomes with low complications rates.

Abstract
Colorectal cancer (CRC), the second most common cancer globally, resulted in 881,000 deaths in 2018. Toll-like receptors (TLRs) are crucial to detecting pathogen invasion and inducing the host’s immune response. This study aimed to explore the prognostic value of TLR2 and TLR4 tumor expressions in colorectal cancer patients. We studied the immunohistochemical expressions of TLR2 and TLR4 using tissue microarray specimens from 825 patients undergoing surgery in the Department of Surgery, Helsinki University Hospital, between 1982 and 2002. We assessed the relationships between TLR2 and TLR4 expressions and clinicopathological variables and patient survival. We generated survival curves using the Kaplan-Meier method, determining significance with the log-rank test. Among patients with lymph node–positive disease and no distant metastases (Dukes C), a strong TLR2 immunoactivity associated with a better prognosis (p < 0.001). Among patients with local Dukes B disease, a strong TLR4 immunoactivity associated with a worse disease-specific survival (DSS; p = 0.017). In the multivariate survival analysis, moderate TLR4 immunoactivity compared with strong TLR4 immunoactivity (hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.49–0.89, p = 0.007) served as an independent prognostic factor. In the multivariate analysis for the Dukes subgroups, moderate TLR2 immunoactivity (HR 2.63, 95% CI 1.56–4.44, p < 0.001) compared with strong TLR2 immunoactivity served as an independent negative prognostic factor in the Dukes C subgroup. TLR2 and TLR4 might be new prognostic factors to indicate which CRC patients require adjuvant therapy and which could spare from an unnecessary follow-up, but further investigations are needed.

Robotic or three-dimensional (3D) laparoscopy for right colectomy with complete mesocolic excision (CME) and intracorporeal anastomosis? A propensity score-matching study comparison. Surg Endosc 2020; 35:2039-2048.

Abstract
BACKGROUND We describe our preliminary experience in complete mesocolic excision (CME) with central vascular ligation (CVL) and intracorporeal anastomosis for right colon cancer, comparing the robotic and the three-dimensional (3D) laparoscopic approach. METHODS We performed a retrospective observational clinical cohort study on patients who underwent radical curative surgical resection of right colon cancer with CME from January 2014 to June 2019. Propensity scores were calculated by bivariate logistic regression, including the following variables: age, BMI, and size of tumor. RESULTS Fifty-five patients underwent CME with CVL: 26 by means of robot-assisted surgery and 29 by means of 3D laparoscopic procedure. There were not statistically significant differences about all the intra- and postoperative outcomes (operative time, length of the specimen, time to bowel canalization, time to soft oral intake, length of hospital stay, postoperative complication, number of retrieved lymph nodes, number of positive lymph nodes and lymph node ratio) between the robotic and the 3D laparoscopic approach. After the matching procedure, 20 patients of the robotic group and 20 patients of the 3D laparoscopic group were selected for the analysis. There were no differences in any of the analyzed variables between the two groups except for longer operative time in the robotic group (p = 0.002). CONCLUSION The 3D vision revealed an important advantage in order to achieve the correct identification of surgical anatomy allowing a safe and effective right colectomy with CME, CVL, and intracorporeal anastomosis, either using laparoscopic or with robotic approach, providing similar short-term outcomes. Taking into account the high costs and the longer operative time of robotic procedure, the 3D laparoscopy could be considered in performing right colectomy with CME, while the robotic approach should be considered as a first choice approach for challenging situations (obese patient, complex associated procedures).

Abstract
Neuroendocrine tumours are the most common type of small bowel neoplasm. Robotic technique may be superior to open technique for lymph node dissection. Robotic-assisted complete mesocolic excision is a safe and effective technique.
Introduction Neuroendocrine tumours are the most common type of primary small bowel neoplasm. Consensus guidelines recommend a multimodal approach to treatment of such tumours, with aggressive surgical resection remaining the mainstay of management. There is evidence that complete mesocolic excision (CME) of lymph nodes is associated with superior oncological outcomes including longer disease-free survival in patients with colorectal cancer than standard lymph node dissection and there is increasing evidence to suggest that the robotic approach may be superior to laparoscopic or open CME. This report discusses a robotic-assisted approach to CME with central vessel ligation (CVL) and para-aortic lymph node dissection in a case of multifocal neuroendocrine tumour of the small bowel. Presentation of case and technical approach This report details the case of a 73-year-old male with multifocal small bowel neuroendocrine tumour. He underwent a robotic-assisted right hemicolectomy, small bowel resection, CME, CVL and para-aortic lymph node dissection. The approach described involved undertaking CME, CVL and bowel resection with a standard right hemicolectomy robotic set-up before re-docking the robot to perform the retroperitoneal para-aortic lymph node dissection. Discussion This case highlights the management of multifocal small bowel neuroendocrine tumour using a robotic approach for surgical resection and lymph node clearance. Conclusion The robotic approach provides a safe and effective technique for undertaking surgical resection of small bowel neuroendocrine tumour as well as complete mesocolic excision of lymph nodes. With a change in port positions, a robotic approach can be utilised for CME/CVL as well as retroperitoneal node dissection.

Abstract
Background Colorectal cancer is the third most commonly diagnosed cancer worldwide. Lymph node (LN) retrieval is a key factor for pathologic staging and prognosis of colorectal cancer. Increase in number of LNs removal suggests improvement in tumour clearance and decrease in metastatic spread. Studies have suggested that excising 12 or more LNs during colectomy in patients with colon cancer is associated with improved survival. To date, there have been no studies to determine whether minimally invasive surgery affects the ability to retrieve 12+ LNs in elective colon cancer surgery. Therefore, we elected to determine whether a difference exists on the ability to retrieve 12+ nodes in elective colon cancer colectomies performed open versus laparoscopic. Methods The National Surgical Quality Improvement Program (NSQIP) Procedure Specific Colectomy database was analysed for the year 2014–2015. Inclusion criteria were colon cancer (ICD-9 Code 153.9), age greater than 18 years. Exclusion criteria were missing data. Data abstracted included patient demographics, type of operation performed and number of LNs retrieved. The patients were categorised based on their elective colon cancer colectomies such as laparoscopic or open. Binary logistic regression was used to identify confounding variables in the retrieval of 12+ LNs. Results After accounting for missing cases, a total of 18,792 patients with a diagnosis of colon cancer were analysed. Twelve or more LNs were retrieved in 88% (16,538) of patients, Among them, 2,516 patients underwent laparoscopic colectomy and 5,284 patients underwent open colectomy. The difference was not statistically significant for the average number of LNs retrieved among both the groups. Open operative approach compared to the laparoscopic approach was associated with 15% greater odds of retrieval of >12 LNs (OR 1.148; 95% CI (1.035–1.272); p = 0.008). Conclusion The majority of colectomies such as open or laparoscopic are able to retrieve 12 or more LNs. However, there are greater odds of retrieving more than 12 LNs with the open approach compared to the laparoscopic approach. By allowing for more LN retrieval, open colectomies suggest improvement in tumour clearance and decrease metastatic spread. Additional research is needed to further investigate the specific factors influencing the ability to retrieve an adequate number of LNs, such as viewing angles provided with an open approach versus laparoscopic approach.

Abstract
PURPOSE During right-sided colectomies, surgeons encounter major anatomical variations at the level of the right colon, leading to morbidity. Due to the confusion surrounding the colonic arterial vessels emerging from the superior mesenteric artery (SMA) to vascularize the right part of the colon, this review aimed to describe the arterial vessels found in the mesocolic structures of the ascending colon, the hepatic flexure and the right transverse colon. METHODS A review of the literature was performed using the MEDLINE database. Only human studies were included. All dissection, angiographic, arterial cast and corrosion studies were analyzed. RESULTS This review demonstrates that the right colon, the hepatic flexure and the right transverse colon are vascularized by three significant arteries emerging from the SMA and forming one peripheral paracolic arc: (1) the ileocolic artery (ICA), the most constant vessel (99.8%) with low variability; (2) the right colic artery (RCA), the most inconstant vessel (2/3 of cases) with high variability in its origin; and (3) the middle colic artery (MCA), a constant vessel (95%) with variation in its origin and its number. The marginal artery is almost constant (100%) and represents the only peripheral arterial arc at the level of the right side of the colon. CONCLUSIONS Three arteries emerging from the superior mesenteric artery exist: the ICA, the RCA and the MCA. The ICA and the MCA are the most constant. Knowledge of this vascular anatomy is essential for performing right-sided colectomies.

Abstract
INTRODUCTION Complete mesocolic excision (CME) is generally accepted as state of the art in colon cancer surgery. However, the long-term impact of CME has not been systematically examined. Therefore cohort studies might be a possible way to clarify any differences between conventional resections and CME. Following bilateral cooperation between the Department of Surgery/University Hospital of Erlangen and the 1st Surgical Department of the General Hospital of Nikaia/Piraeus, including teaching activities for introduction of CME, a cohort study was performed, considering surgical quality criteria and clinical outcome. MATERIAL AND METHODS All patients with colon carcinomas (CME group, n = 31) referred to the 1st Surgical Department of General Hospital, Nikaia/Piraeus, Greece for surgery from January 2012 to December 2013 were prospectively analyzed and compared with patients who underwent conventional surgery for colon cancer between January 2008 and December 2011 (non-CME group, n = 35). Patients' follow-up was at least 48 months. RESULTS There were significantly better results in terms of lymph node yield (CME group: 29.6 vs. non-CME group: 17.85; p < 0.001) and lymph node ratio (LNR) (CME group: 0.12 vs. non-CME group: 0.24; p < 0.001) and recurrence-free survival in favor of the CME group (CME group: n = 0 vs. non-CME group: n = 5) without any increase in surgical morbidity (CME group: n = 6 vs. non-CME group: n = 11; p = 0.10). CONCLUSIONS Complete mesocolic excision appears to offer a superior oncological result without any increase of postoperative morbidity and mortality. Furthermore, CME represents a surgical technique which can be established in a surgical department after previous teaching without increasing the postoperative complication rate.

Abstract
BACKGROUND The observation of inferior oncologic outcomes after surgery for proximal colon cancers has led to the investigation of alternative treatment strategies, including surgical procedures and neoadjuvant systemic chemotherapy in selected patients. OBJECTIVE The purpose of this study was to determine the accuracy of CT staging in proximal colon cancer in detecting unfavorable pathologic features that may aid in the selection of ideal candidates alternative treatment strategies, including extended lymph node dissection and/or neoadjuvant chemotherapy. DESIGN This was a retrospective consecutive series. SETTINGS Trained abdominal radiologists from 2 centers performed a blinded review of CT scans obtained to locally stage proximal colon cancer according to previously defined prognostic groups, including T1/2, T3/4, N+, and extramural venous invasion. CT findings were compared with histopathologic results as a reference standard. Unfavorable pathologic findings included pT3/4, pN+, or extramural venous invasion. PATIENTS Consecutive patients undergoing right colectomy in 2 institutions between 2011 and 2016 were retrospectively reviewed from a prospectively collected database. MAIN OUTCOME MEASURES T status, nodal status, and extramural venous invasion status comparing CT with final histologic findings were measured. RESULTS Of 150 CT scans reviewed, CT failed to identify primary cancer in 18%. Overall accuracy of CT to identify unfavorable pathologic features was 63% with sensitivity, specificity, positive predictive value, and negative predictive value of 63% (95% CI, 54%-71%), 63% (95% CI, 46%-81%), 87% (95% CI, 80%-94%) and 30% (95% CI, 18%-41%). Only cT3/4 (55% vs 45%; p = 0.001) and cN+ (42% vs 58%; p = 0.02) were significantly associated with correct identification of unfavorable features at final pathology. CT scans overstaged and understaged cT in 23.7% and 48.3% and cN in 28.7% and 53.0% of cases. LIMITATIONS The study was limited by its retrospective design, relatively small sample size, and heterogeneity of CT images performed in different institutions with variable equipment and technical details. CONCLUSIONS Accuracy of CT scan for identification of pT3/4, pN+, or extramural venous invasion was insufficient to allow for proper identification of patients at high risk for local recurrence and/or in whom to consider alternative treatment strategies. Locoregional overstaging and understaging resulted in inappropriate treatment strategies in <48%. See Video Abstract at http://links.lww.com/DCR/A935.

Abstract
Backround Several studies have demonstrated a direct correlation between lymph node yield and survival after colectomy for cancer. Complete mesocolic excision (CME) in right colectomy (RC) reduces local recurrence but is technically demanding. Here we report our early single center experience with robotic right colectomy comparing our standardized bottom-to-up (BTU) approach of robotic RC with CME and central vessel ligation (CVL) facilitated by a suprapubic access with the “classical” medial-to-lateral (MTL) strategy. Methods A 4-step BTU approach of robotic RC guided by embryonal planes in the process of retrocolic mobilization with suprapubic port placement was performed in the BTU-group (n = 24; all with intention to treat cancer). In step 1 CME was initiated with caudolateral mobilization of the right colon guided by the fascia of Toldt across the duodenum and up to the Trunk of Henle. Subsequently, dissection was performed BTU right of the middle supramesenteric vessels with central ileocolic vessel ligation in step 2. Subsequent to separation of the transverse retromesenteric space and completion of mobilization the hepatic flexure in step 3, the transverse mesocolon was then transected right of the middle colic vessels in step 4. An extracorporeal side to side anastomosis was performed. We compared the outcome of the BTU-group with a MTL-group (n = 7). Results Patient characteristics like age, gender, BMI, comorbidity (ASA) and M-status were comparable among groups. There was no conversion. Overall complication rate was 35.5%. We experienced no anastomoses insufficiency, grade Dindo/Clavien III/IV complication or mortality in this study. Type I and II complications and surgical characteristics incl. OR-time, ICU- and hospital-stay were comparable between the two groups. However, the lymph node yield was superior in the BTU-group (mean 40.2 ± 17.1) when compared with the MTL-group (16,3 nodes ±8.5; p < 0,001). Conclusions Compared to the classical MTL approach, robotic suprapubic BTU RC changes from a search of the layers bordering the oncological dissection to a consequent utilization of the planes as a retro-mesocolic guide during CME. The BTU strategy could bear the potential to increase the lymph node yield. Robotic systems may provide the technical requirements to combine advantages of both open and minimally invasive RC.

Abstract
Objective To assess whether laparoscopy has any advantages over open resection for right-sided colon cancer. Summary background data Right hemicolectomy can be performed using either a conventional open or a minimally invasive laparoscopic technique. It is not clear whether these different access routes differ with regard to short-term postoperative outcomes. Methods Patients documented in the German Society for General and Visceral Surgery StuDoQ|ColonCancer registry who underwent right hemicolectomy were analyzed regarding early postoperative complications according to Clavien-Dindo (primary endpoint), operation (OP) time, length of postoperative hospital stay (LOS), MTL30 and number of lymph nodes retrieved (secondary endpoints). Results A total of 4.997 patients were identified as undergoing oncological right hemicolectomy without additional interventions. Of these, 4.062 (81.3%) underwent open, 935 (18.7%) laparoscopic surgery. Propensity score analysis showed a significantly shorter LOS (OR: 0.55 CI 95%0.47-.64) and a significantly longer OP time (OR2.32 CI 1.98–2.71) for the laparoscopic route. Risk factors for postoperative complications, anastomotic insufficiency, ileus, reoperation and positive MTL30 were higher ASA status, higher age and increasing BMI. The surgical access route (open / lap) had no influence on these factors, but the laparoscopic group did have markedly fewer lymph nodes retrieved. Conclusion The present registry-based analysis could detect no relevant advantages for the minimally invasive laparoscopic access route. Further oncological analyses are needed to clarify the extent to which the smaller lymph node harvest in the laparoscopic group is accompanied by a poorer oncological outcome.

Abstract
BACKGROUND Quality assessment in surgery is gaining in importance. Although sporadic recommendations for quality indicators (QI) in oncological colon surgery can be found in the literature, these are usually not systematically derived from a solid evidence base. Moreover, reference ranges for QI are unknown. OBJECTIVE The aim of this initiative was the development of evidence-based QI for oncological colon resections by an expert panel invited by the German Society of General and Visceral Surgery (DGAV). Reference ranges from the literature and reference values from the Study, Documentation, and Quality Center (StuDoQ)|Colon Cancer Register were compared in order to deduce recommendations which are tailored to the German healthcare system. RESULTS Based on the most recent scientific evidence and agreed by expert consensus, five QI for oncological colon surgery were defined and evaluated according to the QUALIFY tool. Mortality, MTL30 (mortality, transfer to another acute care hospital, or length of stay ≥30 days), anastomotic leakage requiring reintervention, surgical site infections necessitating reopening of the wound and ≥12 lymph nodes in the specimen qualified as QI owing to their relevance, scientific nature, and practicability. Based on the results of the systematic literature search and the statistical analysis of the StuDoQ|Colon Cancer Register, preliminary reference values are proposed for each QI. CONCLUSION The presented set of QI seems appropriate for quality assessment of oncological colon surgery in the context of the German healthcare system. The validity of the QI and the reference values must be reviewed within the framework of their implementation. The StuDoQ|Colon Cancer Register provides a suitable infrastructure for collecting clinical data for quality assessment and risk adjustment.
