Abstract
Rectal cancer surgery represents challenges due to its location. To overcome them and minimize the risk of anastomosis-related complications, some technical maneuvers or even a diverting ileostomy may be required. One of these technical steps is the mobilization of the splenic flexure (SFM), especially in medium/low rectal cancer. High-tie vascular ligation may be another one. However, the need of these maneuvers may be controversial, as especially SFM may be time-consuming and increase the risk of iatrogenic. The objective is to present the short- and long-term outcomes of a low-tie ligation combined with no SFM in robotic low anterior resection (LAR) for mid- and low rectal cancer as a standardized technique. A retrospective observational single-cohort study was carried out at Reina Sofia University Hospital, Cordoba, Spain. 221 robotic rectal resections between Jul-18th-2018 and Jan-12th-2023 were initially considered. After case selection, 80 consecutive robotic LAR performed by a single surgeon were included. STROBE checklist assessed the methodological quality. Histopathological, morbidity and oncological outcomes were assessed. Anastomotic stricture occurrence and distance to anal verge were evaluated after LAR by rectosigmoidoscopy. Variables related to the ileostomy closure such as time to closure, post-operative complications or hospital stay were also considered. The majority of patients (81.2%) presented a mid-rectal cancer and the rest, lower location (18.8%). All patients had adequate perfusion of the anastomotic stump assessed by indocyanine green. Complete total mesorectal excision was performed in 98.8% of the patients with a lymph node ratio < 0.2 in 91.3%. The anastomotic leakage rate was 5%. One patient (1.5%) presented local recurrence. Anastomosis stricture occurred in 7.5% of the patients. The limitations were small cohort and retrospective design. The non-mobilization of the splenic flexure with a low-tie ligation in robotic LAR is a feasible and safe procedure that does not affect oncological outcomes.

Assessing anatomical variations of the inferior mesenteric artery via three-dimensional CT angiography and laparoscopic colorectal surgery: a retrospective observational study. Sci Rep 2024; 14:6985. [PMID: 38523142 PMCID: PMC10961314 DOI: 10.1038/s41598-024-57661-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 03/20/2024] [Indexed: 03/26/2024] Open
Abstract
To assess the anatomy of the inferior mesenteric artery (IMA) and its branches by reviewing laparoscopic left-sided colorectal cancer surgery videos and comparing them with preoperative three-dimensional computed tomography (3D-CT) angiography, to verify the accuracy of 3D-CT vascular reconstruction techniques. High-definition surgical videos and preoperative imaging data of 200 patients who underwent laparoscopic left-sided colorectal cancer surgery were analysed, and the alignment of the IMA and its branches in relation to the inferior mesenteric vein (IMV) was observed and summarized. The above two methods were used to measure the length of the IMA and its branches. Of 200 patients, 47.0% had the sigmoid arteries (SAs) arise from the common trunk with the superior rectal artery (SRA), and 30.5% had the SAs arise from the common trunk with the left colic artery (LCA). In 3.5% of patients, the SAs arising from both the LCA and SRA. The LCA, SA, and SRA emanated from the same point in 13.5% of patients, and the LCA was absent in 5.5% of patients. The range of D cm (IMA length measured by intraoperative silk thread) and d cm (IMA length measured by 3D-CT vascular reconstruction) in all cases was 1.84-6.62 cm and 1.85-6.52 cm, respectively, and there was a significant difference between them. (p < 0.001). The lengths between the intersection of the LCA and IMV measured intraoperatively were 0.64-4.29 cm, 0.87-4.35 cm, 1.32-4.28 cm and 1.65-3.69 cm in types 1A, 1B, 1C, and 2, respectively, and there was no significant difference between the groups (p = 0.994). There was only a significant difference in the length of the IMA between the 3D-CT vascular reconstruction and intraoperative observation data, which can provide guidance to surgeons in preoperative preparation.

Inferior Mesenteric Artery Ligation Level in Rectal Cancer Surgery beyond Conventions: A Review. Cancers (Basel) 2023; 16:72. [PMID: 38201499 PMCID: PMC10777981 DOI: 10.3390/cancers16010072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 12/13/2023] [Accepted: 12/20/2023] [Indexed: 01/12/2024] Open
Abstract
Within the intricate field of rectal cancer surgery, the contentious debate over the optimal level of ligation of the inferior mesenteric artery (IMA) persists as an ongoing discussion, influencing surgical approaches and patient outcomes. This narrative review incorporates historical perspectives, technical considerations, and functional as well as oncological outcomes, addressing key questions related to anastomotic leakage risks, genitourinary function, and oncological concerns, providing a more critical understanding of the well-known inconclusive evidence. Beyond the dichotomy of high versus low tie, it navigates the complexities of colorectal cancer surgery with a fresh perspective, posing a transformative question: "Is low tie ligation truly reproducible?" Considering a multidimensional approach that enhances patient outcomes by integrating the surgeon, patient, technique, and technology, instead of a rigid and categorical statement, we argued that a balanced response to this challenging question may require compromise.

Abstract
PURPOSE For advanced left colon cancer, lymph node dissection at the root of the inferior mesenteric artery is recommended. Whether the left colic artery (LCA) should be preserved or resected remains contentious. METHODS The 367 patients who underwent laparoscopic sigmoidectomy or anterior resection and who were pathologically node-positive were reviewed. Patients were divided into LCA-preserving group (LCA-P, n = 60) and LCA-non-preserving group (LCA-NP, n = 307). Propensity score matching was applied to minimize selection bias and 59 patients were matched. RESULTS Before matching, the rates of poor performance status and cardiovascular disease were higher in the LCA-P group (p < 0.001). After matching, operation time was longer (276 vs. 240 min, p = 0.001), the frequency of splenic flexure mobilization (62.7% vs. 33.9%, p = 0.003) and lymphovascular invasion (84.7% vs. 55.9%, p = 0.001) was higher in the LCA-P group. Severe postoperative complications (CD ≥ 3) occurred only in the LCA-NP group (0% vs. 8.4%, p = 0.028). The median follow-up period was 38.5 months (range 2.0-70.0 months). The 5-year RFS rates (67.8% vs. 66.0%, p = 0.871) and OS rates (80.4% vs. 74.9%, p = 0.308) were comparable between the groups. CONCLUSIONS Laparoscopic LCA-sparing surgery for left-sided colorectal cancer reduces the risk of severe complications and offers a favorable long-term prognosis.

Abstract
BACKGROUND Colon cancer is a common malignant tumor in the gastrointestinal tract that is typically treated surgically. However, postradical surgery is prone to complications such as anastomotic fistulas. AIM To investigate the risk factors for postoperative anastomotic fistulas and their impact on the prognosis of patients with colon cancer. METHODS We conducted a retrospective analysis of 488 patients with colon cancer who underwent radical surgery. This study was performed between April 2016 and April 2019 at a tertiary hospital in Wuxi, Jiangsu Province, China. A t-test was used to compare laboratory indicators between patients with and those without postoperative anastomotic fistulas. Multiple logistic regression analysis was performed to identify independent risk factors for postoperative anastomotic fistulas. The Functional Assessment of Cancer Therapy-Colorectal Cancer was also used to assess postoperative recovery. RESULTS Binary logistic regression analysis revealed that age [odds ratio (OR) = 1.043, P = 0.015], tumor, node, metastasis stage (OR = 2.337, P = 0.041), and surgical procedure were independent risk factors for postoperative anastomotic fistulas. Multiple linear regression analysis showed that the development of postoperative anastomotic fistula (P = 0.000), advanced age (P = 0.003), and the presence of diabetes mellitus (P = 0.015), among other factors, independently affected prognosis. CONCLUSION Postoperative anastomotic fistulas significantly affect prognosis and survival rates. Therefore, focusing on the clinical characteristics and risk factors and immediately implementing individualized preventive measures are important to minimize their occurrence.

Abstract
OBJECTIVE The aim of this systematic review and meta-analysis is to summarize the current scientific evidence regarding the impact of the level of inferior mesenteric artery (IMA) ligation on post-operative and oncological outcomes in rectal cancer surgery. METHODS We conducted a systematic review of the literature up to 06 September 2022. Included were RCTs that compared patients who underwent high (HL) vs. anterior (LL) IMA ligation for resection of rectal cancer. The literature search was performed on Medline/PubMed, Scopus, and the Web of Science without any language restrictions. The primary endpoint was overall anastomotic leakage (AL). Secondary endpoints were oncological outcomes, intraoperative complications, urogenital functional outcomes, and length of hospital stay. RESULTS Eleven RCTs (1331 patients) were included. The overall rate of AL was lower in the LL group, but the difference was not statistically significant (RR 1.43, 95% CI 0.95 to 2.96). The overall number of harvested lymph nodes was higher in the LL group, but the difference was not statistically significant (MD 0.93, 95% CI - 2.21 to 0.34). The number of lymph nodes harvested was assessed in 256 patients, and all had a laparoscopic procedure. The number of lymph nodes was higher when LL was associated with lymphadenectomy of the vascular root than when IMA was ligated at its origin, but there the difference was not statistically significant (MD - 0.37, 95% CI - 1.00 to 0.26). Overall survival at 5 years was slightly better in the LL group, but the difference was not statistically significant (RR 0.98, 95% CI 0.93 to 1.05). Disease-free survival at 5 years was higher in the LL group, but the difference was not statistically significant (RR 0.97, 95% CI 0.89 to 1.04). CONCLUSIONS There is no evidence to support HL or LL according to results in terms of AL or oncologic outcome. Moreover, there is not enough evidence to determine the impact of the level of IMA ligation on functional outcomes. The level of IMA ligation should be chosen case by case based on expected functional and oncological outcomes.

Abstract
Background: To evaluate the safety and efficacy of left colic artery (LCA) preservation in laparoscopic anterior resection with D3 lymphadenectomy for lower rectal cancer. Methods: A total of 117 patients with lower rectal cancer who received laparoscopic anterior resection were retrospectively analyzed. Results: No differences were detected in terms of the numbers of harvested lymph nodes and metastatic lymph nodes, the intraoperative and postoperative complications or the postoperative recurrence and survival rates between the two groups (p > 0.05), but the LCA preservation group showed a lower anastomotic leakage rate than the LCA nonpreservation group (2/49 vs 12/68). Conclusion: LCA preservation may help reduce the incidence of anastomotic leakage without impairing surgical and oncological outcomes.

Verification of blood flow path reconstruction mechanism in distal sigmoid colon and rectal cancer after high IMA ligation through preoperative and postoperative comparison by manual subtraction CTA. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:1269-1274. [PMID: 36658053 DOI: 10.1016/j.ejso.2023.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Accepted: 01/11/2023] [Indexed: 01/13/2023]
Abstract
INTRODUCTION We aimed to investigate manual subtraction computed tomography angiography (MS-CTA) to further confirm the distribution and classification of LCA (left colic artery) ascending/descending branches, then observe the postoperative blood flow path to illustrate how the above branches evolved to postoperative blood path. MATERIAL AND METHODS 89 patients with distal sigmoid and rectal cancer were referred in our observation and underwent MS-CTA between June 2020 and March 2022. We classified the distribution of LCA and confirmed whether there exists AMCA (accessory middle colic artery). Then we planned blood flow path based on the classification of LCA branches before operation. High ligation was applied in regular radical surgery. During operation, we carefully protect the bifurcation of ascending and descending LCA. Then we compared the planned blood flow path with the actual postoperative blood flow path to verify the mechanism we proposed previously. RESULTS Of 89 patients, 82 cases met our criteria, we summarized 6 distribution pattens of LCA ascending and descending branches. These preoperative pattens are consistent with the inspection during operation. The postoperative blood flow path of 6 pattens is evolved from the above adjacent anastomotic branches and is consistent with the planned blood flow path. We also found 2 cases with IMA stenosis and 1 case with SMA stenosis under pathological condition, and their compensatory blood flow path is in accordance with our theory. The rate of the anastomotic leakage in our study group is relatively low (7.3%). CONCLUSION MS-CTA could confirm the distribution of LCA and AMCA, display accurate postoperative blood reconstruction path after IMA high ligation, and it further verified the mechanism we proposed previously, which is the proximal anastomotic branches forming new blood flow path from high-pressure area to the low-pressure area. This mechanism might be helpful for performing accurate laparoscopic sigmoid and rectal cancer surgery.

Abstract
PURPOSE Anastomotic leakage (AL) is one of the severe complications after rectal surgery, and anastomotic ischemia is one of the main factors. This prospective in vivo pilot study aimed to evaluate the effectiveness of Sidestream Dark Field (SDF) imaging in quantitative assessment of anastomotic microcirculation and to analyze its correlation with AL. METHODS Thirty-three patients with rectal cancer who underwent laparoscopic low anterior resection from 2019 to 2020 were enrolled. Microcirculation was measured by SDF imaging at the descending colon, the mesocolon transection line (MTL), and 1 cm and 2 cm distal to the MTL. Anastomotic microcirculation was measured at the stapler anvil edge before anastomosis. Quantitative perfusion-related parameters were as follows: microcirculation flow index (MFI), perfused vessel density (PVD), proportion of perfused vessels (PPV), and total vessel density (TVD). RESULTS All patients obtained stable microcirculation images. Functional microcirculation parameters (MFI, PPV, PVD) decreased successively from the descending colon, the colon at MTL, and 1 cm and 2 cm distal to the MTL (all P < 0.01). Extremely poor microcirculation was found at the intestinal segment 2 cm distal to the MTL. Micro-perfusion was significantly lower at the colonic limb of the anastomosis compared with the descending colon (all P < 0.001). Anastomotic leakage occurred in 3 patients (9.1%) whose anastomotic microcirculation was significantly lower than those without AL (all P < 0.01). Blood perfusion at the colonic limb of the anastomosis was significantly higher in patients with left colic artery preservation than in controls. CONCLUSION SDF imaging is a promising technique for evaluating anastomotic microcirculation and has potential clinical significance for risk stratification of AL.

Comparison of High Ligation Versus Low Ligation of the Inferior Mesenteric Artery (IMA) on Short-Term and Long-Term Outcomes in Sigmoid Colon and Rectal Cancer Surgery: A Meta-analysis. Cureus 2023; 15:e39406. [PMID: 37362536 PMCID: PMC10287114 DOI: 10.7759/cureus.39406] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/23/2023] [Indexed: 06/28/2023] Open
Abstract
This study was done to compare the perioperative outcomes and long-term outcomes between low ligation and high ligation of the inferior mesentric artery (IMA) in sigmoid colon and rectal cancer surgery. This study was conducted following the recommendations of the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). A literature search was performed in electronic databases including PubMed, CINAHIL, EMBASE, and Web of Science to identify studies published between January 1, 2015, and April 30, 2023. The outcomes assessed in this meta-analysis included postoperative complications (anastomotic leakage, surgical site infection, and postoperative ileus), intraoperative outcomes (duration of surgery in minutes, total intraoperative blood loss in milliliters, total lymph nodes harvested, and total number of metastatic lymph nodes), recovery outcomes (time to first flatus and length of hospital stay), and long-term outcomes (five-year mortality rate and disease-free survival rate). A total of 17 studies were included in this meta-analysis. Of these, six were randomized control trials (RCTs) and 11 were retrospective cohort studies. This meta-analysis suggests that lower ligation may be associated with a lower risk of anastomotic leakage compared to higher ligation in patients undergoing colon cancer surgery. However, there was no significant difference between the two techniques in terms of surgical site infection, postoperative ileus, total lymph nodes harvested, number of metastatic lymph nodes, duration of surgery, intraoperative blood loss, and length of hospital stay. Time to first flatus was significantly shorter in patients who underwent lower ligation. Additionally, there were no significant differences in the five-year mortality rate and disease-free survival rate between the two techniques. The results of this study indicate that both techniques are comparable in most aspects and suggest that the choice of technique should be based on individual patient factors and surgeon preference.

Abstract
BACKGROUND D3 lymph node dissection with left colic artery (LCA) preservation in rectal cancer surgery seems to have little effect on reducing postoperative anastomotic leakage. So we first propose D3 lymph node dissection with LCA and first sigmoid artery (SA) preservation. This novel procedure deserves further study. METHODS Rectal cancer patients who underwent laparoscopic D3 lymph node dissection with LCA preservation or with LCA and first SA preservation between January 2017 and January 2020 were retrospectively assessed. The patients were categorized into two groups: the preservation of the LCA group and the preservation of the LCA and first SA group. A 1:1 propensity score-matched analysis was performed to decrease confounding. RESULTS Propensity score matching yielded 56 patients in each group from the eligible patients. The rate of postoperative anastomotic leakage in the preservation of the LCA and first SA group was significantly lower than that in the LCA preservation group (7.1% vs. 0%, P=0.040). No significant differences were observed in operation time, length of hospital stay, estimated blood loss, length of distal margin, lymph node retrieval, apical lymph node retrieval, and complications. A survival analysis showed patients' 3-year disease-free survival (DFS) rates of group 1 and group 2 were 81.8% and 83.5% (P=0.595), respectively. CONCLUSION D3 lymph node dissection with LCA and first SA preservation for rectal cancer may help reduce the incidence of anastomotic leakage without compromising oncological outcomes compare with D3 lymph node dissection with LCA preservation alone.

Abstract
Background Limited data are available about superior rectal artery (SRA) preservation in laparoscopic resection for sigmoid colon cancer (SCC). This study aimed to evaluate the short-term and long-term efficacies of SRA preservation in laparoscopic radical resection for SCC. Methods We retrospectively analyzed 207 patients with SCC who underwent laparoscopic radical resection for SCC from January 2017 to June 2021. A total of 84 patients received lymph node clearance around the inferior mesenteric artery (IMA) root (D3 lymph node dissection) with preservation of SRA (SRA preservation group), and 123 patients received high ligation of the IMA (control group). The clinicopathological data of the two groups were compared, and Kaplan-Meier method was performed to estimate patient survival. Results Compared with the control group, the operation time of the SRA preservation group was longer (p < 0.001), but the postoperative exhaust and defecation times were significantly shorter (p = 0.003, p < 0.001). Two cases of postoperative ileus and four cases of anastomotic leakage were observed in the control group, whereas the SRA preservation group had none. However, no statistical difference was observed between the groups (p = 0.652, p = 0.248). The overall survival also showed no significant difference in (p = 0.436). Conclusion Preservation of SRA plus dissection of lymph nodes around IMA did not increase postoperative morbidity and mortality nor affect the prognosis of patients but increased the bowel blood supply, which may have a significant positive effect on the recovery of postoperative intestinal function and reduction of anastomotic leakage.

Abstract
Backgroud The high or low inferior mesenteric artery (IMA) ligation in rectal cancer remains a great debate. This study retrospectively discussed the outcomes of the perioperative period, defecation and urinary function and long-term prognosis in rectal cancer patients with high or low IMA ligation. Methods This study enrolled 220 consecutive rectal cancer cases, including 134 with high IMA ligation and 86 with low ligation. A comparison between the two groups was made for anastomotic leakage, low anterior resection syndrome (LARS), international prostate symptom score (IPSS), 5-year disease-free survival (DFS) and 5-year overall survival (OS). Results Low-ligation group had a longer operative time, and larger intraoperative blood loss. No significant difference was noted in anastomotic leakage incidence. In multivariable analysis, the male gender and tumor located at the lower rectum were identified as risk factors for anastomotic leakage. No significant differences were observed between groups in their LARS and IPSS questionnaire responses. The high-ligation vs. the low-ligation 5-year OS and DFS were 78.3% vs. 82.4% and 72.4% vs. 76.6%, respectively, which were not statistically different. Conclusion The ligation level of the IMA had no significant effect on the anastomotic leakage incidence, defecation, urinary function, and long-term prognosis.

Abstract
Colorectal cancer is one of the most common surgically curable malignancies worldwide, having a good prognosis even with liver metastasis. This improved patient outcome is marred by anastomotic leaks (AL) in operated patients of colorectal cancer despite a microscopically margin-negative resection (R0). Various risk factors have been attributed to causing this. Preoperative non-modifiable factors are age, male sex, cancer cachexia, and neoadjuvant chemo-radiotherapy, and modifiable factors are comorbidities, peripheral vascular disease, anemia, and malnutrition. Intraoperative risk factors include intraoperative surgical duration, blood loss and transfusions, fluid management, oxygen saturation, surgical technique (stapled, handsewn, or compression devices), and approach (open, laparoscopic, or robotic). Postoperative factors like anemia, infection, fluid management, and blood transfusions also have an effect. With the advent of enhanced recovery after surgery (ERAS) protocols, many modifiable factors can be optimized to reduce the risk. Prevention is better than cure as the morbidity and mortality of AL are very high. There is still a need for an intraoperative technique to detect the viability of anastomotic ends to predict and prevent AL. Prompt diagnosis of an AL is the key. Many surgeons have proposed using methods like air leak tests, intraoperative endoscopy, Doppler ultrasound, and near-infrared fluorescence imaging to decrease the incidence of AL. All these methods can minimize AL, resulting in significant intraoperative alterations to surgical tactics. This narrative review covers the methods of assessing of integrity of anastomosis during the surgery, which can help prevent anastomotic leakage.

Abstract
OBJECTIVE The purpose of this study was to perform a meta-analysis comparing the oncological, intraoperative and safety outcomes in laparoscopic rectal cancer surgery with and without preservation of the left colic artery (LCA). METHOD We searched several databases including PubMed, Web of Science, Cochrane Library, and Embase databases. This meta-analysis included randomized clinical trials, prospective, and retrospective comparative studies regarding high- or modified low-tie ligation of the inferior mesenteric artery in laparoscopic rectal cancer surgery. RESULTS Of 641 potentially eligible articles, 16 studies with 3050 participants met the eligibility criteria and were included in the meta-analysis. There was no significant difference in estimated blood loss (WMD -2.63, 95% CI -5.69 to 0.43; P = .09), the number of harvested lymph nodes (WMD -0.35, 95% CI -1.60 to 0.20; P = .50), the number of apical lymph node yield (WMD -0.19, 95% CI -0.52 to 0.13; P = .24), the number of apical lymph node metastasis (OR 0.76, 95% CI 0.40 to 1.45; P = .40), rate of conversion to open surgery (OR 0.74, 95% CI 0.50 to 1.09; P = .513), rate of urinary dysfunction (OR 1.39, 95% CI 0.71 to 2.74; P = .34), rate of recurrence and metastasis (OR 1.10, 95% CI 0.75 to 1.61; P = .64), 5-year survival rate (OR 0.89, 95% CI 0.67 to 1.18; P = .42). However, this meta-analysis demonstrated a statistically significant difference in operating time (WMD -9.92, 95% CI -15.49 to -5.84; P = .0005), rate of diverting stom (OR 1.42, 95% CI 1.06 to 1.92; P = .02), rate of anastomotic leakage (OR 2.673, 95% CI 1.91 to 3.62; P < .00001), time to first flatus (WMD 0.29, 95% CI 0.11 to 0.48; P = .002), time of hospitalization (WMD 0.64, 95% CI 0.14 to 1.15; P = .01) between the 2 surgical techniques. COCLUSION The available evidence suggests that preserving the left colic artery is a safe, effective technique for patients with laparoscopic rectal cancer. nique for patients with laparoscopic rectal cancer.

Anastomotic leak after minimally invasive anterior resection for rectal cancer with high versus low ligation of the inferior mesenteric artery: a study protocol for a multicentre randomized clinical trial. Trials 2022; 23:920.

Abstract
BACKGROUND Although many efforts have been made to decrease the incidence of anastomotic leak (AL), it remains one of the most serious complications of rectal cancer surgery. Many previous studies have reported an association between the ligation level of the inferior mesenteric artery (IMA) (high or low) and the incidence of AL after rectal cancer surgery. However, we cannot draw a solid conclusion because of the low quality and heterogeneity of those studies. Therefore, this study aims to investigate the impact of the IMA ligation level on the occurrence of AL after minimally invasive anterior resection of rectal cancer. METHODS/DESIGN Patients with primary rectal cancer without distant metastases will be included after screening. They will be randomly assigned (1:1) to receive high or low ligation of the IMA. The primary endpoint is AL incidence; secondary endpoints are quality of life; urinary, sexual, and defecatory functions; and 3-year disease-free survival. We hypothesized that the incidence rate of AL would be 15% and 5% in the high- and low-ligation groups, respectively. With a two-sided α of 0.05 and a power of 0.8, the sample size is calculated to be 314 patients (157 per group), considering a 10% dropout rate. DISCUSSION Although many studies have compared the short- and long-term outcomes of high and low ligation of the IMA in rectal cancer surgery, it is still debatable. This trial aims to help draw a more solid conclusion regarding the association between the IMA ligation level and AL incidence after rectal cancer surgery. We also hope to contribute to standardizing the method of rectal cancer surgery in this trial. TRIAL REGISTRATION Clinical Research Information Service KCT0003523. Registered on February 18, 2019.

BACKGROUND Anastomotic blood supply is vital to anastomotic healing. The aim of this study was to demonstrate the effect of the left colic artery (LCA) on blood supply in the anastomotic area, explore the relationship between individual differences in the LCA and blood supply in the anastomotic area, and elucidate the relevant indications for LCA retention during radical resection for sigmoid or rectal cancer. METHOD Radical sigmoid or rectal cancer resection with LCA retention was performed in 40 patients with colorectal cancer who participated in this study. Systemic pressure, LCA diameter, and the distance from the root of the LCA to the root of the inferior mesenteric artery were measured and recorded. The marginal artery stump pressure in the anastomotic colon before and after the LCA clamping was measured, respectively. RESULTS There is a significant difference between the marginal artery stump pressure before LCA ligation and after ligation (53.1 ± 12.38 vs 42.76 ± 12.71, p < 0.001). The anastomotic blood supply positively and linearly correlated with body mass index and systemic pressure. Receiver-operating curve analysis revealed that LCA diameter (area under the curve 0.971, cutoff 1.95 mm) was an effective predictor of LCA improving anastomosis blood supply. No relationship was found between the LCA root location and anastomotic blood supply. CONCLUSION Preserving the LCA is effective in improving blood supply in the anastomotic area, and larger LCA diameters result in a better blood supply to the anastomotic area.

Zeng S, Wu W, Zhang X, Qiu T, Gong P. The significance of anatomical variation of the inferior mesenteric artery and its branches for laparoscopic radical resection of colorectal cancer: a review. World J Surg Oncol 2022; 20:290. [PMID: 36085239 PMCID: PMC9463869 DOI: 10.1186/s12957-022-02744-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 08/02/2022] [Indexed: 11/10/2022] Open
Abstract
Currently, high or low ligation of the inferior mesenteric artery (IMA) is a controversial issue in laparoscopic radical surgery for colorectal cancer. High or low ligation of the IMA has both advantages and disadvantages, and the level of ligation during the left colon and/or rectum resection has been a dilemma for surgeons. One important factor influencing the surgeon's decision to ligate the IMA in a high or low position is the anatomical type of the IMA and its branches. Some studies confirm that the anatomy of the IMA and its branches is critical to the anastomotic blood supply and, therefore, influences the choice of surgical approach (level of ligation of the IMA). However, many vascular variations in the anatomy of the IMA and its branches exist. Herein, we have summarized the anatomical types of the IMA and its branches, finding that the classification proposed by Yada et al. in 1997 is presently accepted by most scholars. Based on Yada's classification, we further summarized the characteristics of the IMA's various anatomical types as a guide for high or low ligation in radical colorectal cancer surgery.

Abstract
Background and Objectives: This study aimed to compare the effects of high ligation (HL) versus low ligation (LL) in colorectal cancer surgery. Materials and Methods: We performed a comprehensive search using multiple databases (trial registries and ClinicalTrials.gov), other sources of grey literature, and conference proceedings, with no restrictions on the language or publication status, up until 10 March 2021. We included all parallel-group randomized controlled trials (RCTs) and considered cluster RCTs for inclusion. The risk of bias domains were "low risk," "high risk," or "unclear risk." We performed statistical analyses using a random-effects model and interpreted the results according to the Cochrane Handbook for Systematic Reviews of Interventions. We used the GRADE guidelines to rate the certainty of evidence (CoE) of the randomized controlled trials. Results: We found 12 studies (24 articles) from our search. We were very uncertain about the effects of HL on overall mortality, disease recurrence, cancer-specific mortality, postoperative mortality, and anastomotic leakage (very low CoE). There may be little to no difference between HL and LL in postoperative complications (low CoE). For short-term follow-up (within 6 months), HL may reduce defecatory function (constipation; low CoE). While HL and LL may have similar effects on sexual function in men, HL may reduce female sexual function compared with LL (low CoE). For long-term follow-up (beyond 6 months), HL may reduce defecatory function (constipation; low CoE). There were discrepancies in the effects regarding urinary dysfunction according to which questionnaire was used in the studies. HL may reduce male and female sexual function (low CoE). Conclusions: We are very uncertain about the effects of HL on survival outcomes, and there is no difference in the incidence of postoperative complications between HL and LL. More rigorous RCTs are necessary to evaluate the effect of HL and LL on functional outcomes.

Abstract
BACKGROUND Preserving the left colic artery (LCA) during anterior resection for rectal cancer is controversial, and robust evidence of the outcomes of LCA preservation plus apical lymph node dissection is lacking. The purpose of this study was to investigate the impact of LCA preservation plus apical lymph node dissection surgery on anastomotic leakage and number of harvested lymph nodes. METHODS Patients who underwent laparoscopic or robotic anterior resection for rectal cancer between September 2017 and May 2020 were retrospectively assessed. The patients were categorized into two groups: preservation of LCA and nonpreservation of LCA. A one-to-one propensity score-matched analysis was performed to decrease confounding. The primary outcome was anastomotic leakage within 30 days after surgery. The secondary outcomes were number of harvested lymph nodes, 3-year overall survival, and 3-year disease-free survival. RESULTS A total of 216 patients were eligible for this study, and propensity score matching yielded 60 patients in each group. Anastomotic leakage in the LCA preservation group was significantly lower than that in the LCA nonpreservation group (3.3% vs. 13.3%, P = 0.048). No significant differences were observed in blood loss, operation time, intraoperative complications, splenic flexure mobilization, total number of harvested lymph nodes, number of positive lymph nodes, time to first flatus, or postoperative hospital stay. Kaplan-Meier survival analysis showed a 3-year disease-free survival of 85.7% vs. 80.5% (P = 0.738) and overall survival of 92.4% vs. 93.7% (P = 0.323) for the preservation and nonpreservation groups, respectively. CONCLUSION LCA preservation plus apical lymph node dissection surgery for rectal cancer may help reduce the incidence of anastomotic leakage without impairing the number of harvested lymph nodes. Preliminary results suggest that 3-year disease-free survival and overall survival rates may not differ between the two types of surgery, but studies with larger sample sizes are needed to confirm these conclusions.

Abstract
OBJECTIVES The objective of this study is to analyze the main patterns of branching of the inferior mesenteric artery (IMA) and to determine if your knowledge changes the surgical strategy in the colorectal cancer. METHODS This retrospective study included 63 patients with cancer of the sigmoid or rectum. We assessed the patterns of IMA in 3 subtypes: type A (independent left colic artery [LCA]), type B (LCA and sigmoid artery arising in a common trunk) and type C (LCA, sigmoid artery, and superior rectal artery with a common origin). Colorectal surgeons evaluated how the vascular map changed the type of IMA ligation. RESULTS Inferior mesenteric artery branching was classified as type A in 55.6% patients, type B in 23.8%, and type C in 20.6%. Knowledge of the vascular map changed the type of ligation from high to low in 20 of the 50 patients who were candidates for surgery. The change was possible in tumors located in the sigmoid colon and the rectosigmoid junction with the type A or B branching. CONCLUSIONS Preoperative Multidetector Computed Tomography angiography can define the pattern of IMA branching. Based on this information, a low ligation can be performed in tumors located in sigmoid colon and rectosigmoid junction with IMA branching types A and B.

Abstract
Background Laparoscopic low anterior rectal resection is the most widely used surgical procedure for middle and low rectal cancer. The aim of this study was to investigate the feasibility and safety of the extracorporeal placement of the anvil in preserving the left colic artery in laparoscopic low anterior rectal resection without auxiliary incisions for transanal specimen retrieval in this research. Methods Clinical data and follow-up data of patients undergoing laparoscopic low anterior rectal resection from January 2017 to October 2020 were collected. The resections were modified such that the resisting nail holder was extracorporeally placed for the transanal exenteration of the specimen without using auxiliary abdominal incisions while preserving the left colic artery. By analyzing the data of anastomotic stenosis, anastomotic bleeding and anastomotic fistulas after surgery, the advantages and disadvantages of this surgical method for patients were clarified. Results A total of 22 patients were enrolled. Five of 22 patients simultaneously underwent double-barrel terminal ileostomy. The postoperative exhaust time was 2–7 (median, 3) days. Postoperative anastomotic bleeding occurred in one patient, postoperative anastomotic fistula occurred in four patients, and postoperative anastomotic stenosis occurred in six patients. There were four patients with postoperative distant metastasis, of which three had concomitant local recurrence. Seventeen patients had no obvious symptoms or signs of recurrent metastases during follow-up appointments, and one died of liver failure. Conclusions Modified laparoscopic low anterior rectal resection, which resects the specimen through anus eversion by inserting the anvil extracorporeally while preserving the left colic artery, is safe and feasible for patients with low rectal cancer.

Abstract
Background Whether high or low ligation of the inferior mesenteric artery (IMA) is superior in surgery for rectal and sigmoid colon cancers remains controversial. Although several meta-analyses have been conducted, the level of lymph node clearance was poorly defined. We performed a meta-analysis comparing high and low ligation of the IMA for sigmoid colon and rectal cancers, with emphasis on high dissection of the lymph node at the IMA root in all the included studies. Methods PubMed, MEDLINE, and EMBASE databases were searched to identify relevant articles published until 2020. The patient’s perioperative and oncologic outcomes were analyzed. Statistical analysis was performed using the statistical software RevMan version 5.4. Results A total of 17 studies, including four randomized controlled trials, published between 2011 and 2020 were selected. In total, 1,846 patients received low ligation of the IMA plus high dissection of lymph nodes (LL+HD), and 2,648 patients received high ligation of the IMA (HL). LL+HD was associated with low incidence of anastomotic leakage (p < 0.001), borderline long operative time (p = 0.06), and less yields of total lymph nodes (p = 0.03) but equivalent IMA root lymph nodes (p = 0.07); moreover, LL+HD exhibited non-inferior long-term oncological outcomes. Conclusion In comparison with HL, LL+HD was an effective and safe oncological procedure for sigmoid colon and rectal cancers. Therefore, to ligate the IMA below the level of the left colic artery with D3 high dissection for sigmoid colon and rectal cancers might be suggested once the surgeons are familiar with this technique.

Level of inferior mesenteric artery ligation does not affect rectal cancer treatment outcomes despite better cancer-specific survival after low ligation-randomized trial results. Colorectal Dis 2021; 23:2575-2583. [PMID: 34251082 DOI: 10.1111/codi.15798] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 06/20/2021] [Accepted: 06/22/2021] [Indexed: 12/14/2022]
Abstract
AIM In rectal cancer surgery, the problem about which of the mesenteric artery ligation variants (high or low) is more beneficial to the patient remains unsolved. Recent meta-analyses suggest that the risk of surgical complications is similar for both ligation variants. The main objective was to compare the survival time in both groups with a minimum 48 months' follow-up. Secondary objectives were comparison of the number of harvested lymph nodes, the complication rate and other selected data related to the surgery. METHOD This was a randomized, single-centre, unblinded clinical trial of adult patients (n = 130) with cT1-3M0/ycT0-3M0 rectal and rectosigmoid junction adenocarcinoma undergoing radical open surgery. The intervention level was inferior mesenteric artery ligation. RESULTS The mean and median survival in the whole group was 45 months, while in the survivor group it was 83 and 82 months. The survival for 1-5 years, overall survival and disease-free survival were similar in both groups. The cancer-specific survival time was longer in the low inferior mesenteric artery ligation group (P = 0.005 for all and P = 0.02 for pTNM Stage III patients) There were no differences in the incidence of anastomotic leakage and overall morbidity. The median number of lymph nodes located at the root of the inferior mesenteric artery was 1; the mean was 1.7. They were not metastatic in any case. The median total number of harvested nodes was similar in both groups. CONCLUSIONS In radically treated adenocarcinoma of the rectum and the rectosigmoid junction, the level of inferior mesenteric artery ligation below the left colic artery branch provides similar treatment results to inferior mesenteric artery ligation just below its branching from the aorta in relation to overall and disease-free survival, and the risk of complications. Low inferior mesenteric artery ligation results in better cancer-specific survival. The risk of metastases at the mesenteric nodes is negligible.

Clinical effect and standardization of indocyanine green angiography in the laparoscopic colorectal surgery. JOURNAL OF MINIMALLY INVASIVE SURGERY 2021; 24:113-122. [PMID: 35600102 PMCID: PMC8977386 DOI: 10.7602/jmis.2021.24.3.113] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 09/06/2021] [Accepted: 09/08/2021] [Indexed: 02/07/2023]
Abstract
Anastomotic complications occur after 5% to 20% of operations for rectosigmoid colon cancer. The intestinal perfusion status at the anastomotic site is an important modifiable risk factor, and surgeons should carefully evaluate and optimize the perfusion at the intended site of anastomosis. Indocyanine green (ICG) angiography is a simple noninvasive perfusion assessment modality. The use of ICG angiography is rapidly spreading in the field of colorectal surgery. However, there is debate on its contribution to reducing anastomotic complications. In this review, we discuss the clinical utility and the standardization of ICG angiography. ICG angiography can unequivocally reveal unfavorable perfusion zones and provide quantitative parameters to predict the risk of hypoperfusion-related anastomotic complications. Many studies have demonstrated the clinical utility of ICG angiography for reducing anastomotic complications. Recently, two multicenter randomized clinical trials reported that ICG angiography did not significantly reduce the incidence of anastomotic leakage. Most previous studies have been small-scale single-center studies, and there is no standardized ICG angiography protocol to date. Additionally, ICG angiography evaluations have mostly relied on surgeons’ subjective judgment. For these reasons, it is necessary to establish a standardized ICG angiography protocol and develop a quantitative analysis protocol for the objective assessment. In conclusion, ICG angiography could be useful for detecting poorly perfused colorectal segments to prevent anastomotic leakage after colorectal surgery. An optimized and standardized ICG angiography protocol should be established to improve the reliability of perfusion assessments. In the future, artificial intelligence-based quantitative analyses could be used to easily assess colonic perfusion status.

Abstract
The level of ligation of the inferior mesenteric artery (IMA) is a critical factor that can influence outcomes. The aim of this meta-analysis was to compare outcomes following high or low ligation of IMA. A systematic search was performed for relevant articles published between 2000 and 2020. Meta-analysis was performed using fixed-effects or random-effects models; 31 studies were included. Results show significantly lower rates of anastomotic leak, postoperative morbidity and urinary dysfunction with low ligation compared with high ligation. Though recurrence rates were similar, 5-year overall survival was longer in the low ligation group. Low ligation of IMA decreases anastomotic leak rates and overall morbidity. Addition of IMA nodal clearance to low ligation appears to improve overall survival in colorectal cancer.

Abstract
Background: Total mesorectal resection (TME) has become the standard surgical procedure for resection of colorectal cancer tumors. We presented a systematic meta-analysis to evaluate the surgical outcomes of laparoscopic TME surgery with preservation or nonpreservation of both the superior rectum artery (SRA) and left colonic artery (LCA) for upper-rectal and sigmoid colon cancers. Methods: The comparative studies were systematically searched on PubMed, Science Direct, Web of Science, Wanfang Data, and China National Knowledge Infrastructure (CNKI) up to April 2021. Primary outcomes were oncology outcomes. And secondary outcomes involved surgical outcomes of interest and postoperative recovery. Results: Five relevant studies with a total of 761 patients undergoing laparoscopic TME surgery were eligible for meta-analysis. Three hundred seven patients received TME with preservation of both SRA and LCA (Group A), and 454 received TME surgery alone (Group B), respectively. Our results indicated that Group A had a less total postoperative complications (P = .000), lower anastomotic leakage rate (P = .002), shorter length of stay (P = .008), and longer operative time (P = .002). However, there was no significant difference between the two groups in terms of lymph node dissections (P = .188), intraoperative bleeding (P = .474), the first postoperative defecation (P = .943), recurrence rate (P = .547), and conversive rate (P = .504). Conclusions: Based on our meta-analysis, laparoscopic TME surgery with preservation of both the SRA and LCA for upper-rectal and sigmoid colon cancers may significantly receive better clinical and surgical outcomes. More well-designed large sample studies are required to replicate the short-term benefits and long-term oncologic outcomes.

Abstract
BACKGROUND Unlike the tumor nodes metastasis (TNM) lymph node classification, based solely on counts of nodal metastases, the Japanese system of classifying colorectal carcinoma (CRC) focuses on regional lymph node spread. In this study, we explored the prognostic utility of inferior mesenteric artery (IMA) apical lymph node (APN) metastasis. PATIENTS AND METHODS This was a retrospective study of patients with stage III left-sided CRC. All enrollees were subjected to D3 resection between April 2007 and December 2016 at the International Medical Center of Saitama Medical University and then stratified by histologic presence (APN+ group) or absence (APN- group) of tumor in APNs examined postoperatively. Ultimately, propensity score matching was invoked (1:2) and COX regression analysis was conducted, determining group rates of relapse-free survival (RFS) and cancer-specific survival (CSS). RESULTS A total of 498 patients were studied, grouped as APN+ (19/498, 3.8%) or APN- (479/498, 96.2%). Prior to matching, the APN+ (vs. APN-) group showed significantly more lymphatic involvement (73.7% vs. 47.8%; p=0.023), deep (T3/T4) tumor infiltration (100% vs. 78.9%; p=0.024), and nodal metastasis (N2: 84.2% vs. 27.6%; p<0.001). In addition, para-aortic nodal recurrences were significantly increased (15.7% vs. 2.0%; p<0.001), conferring worse RFS (p<0.001) and CSS (p=0.014) rates. Once baseline factors were matched, the two groups appeared similar in RFS (p=0.415) and CSS (p=0.649). Multivariate regression analysis indicated that elevated carcinoembryonic antigen (CEA) level and deep tumor infiltration were independent risk factors for RFS, whereas postoperative complications and tumor-positive node counts were independent risk factors for CSS. APN+ status was not a significant risk factor for RFS or CSS. CONCLUSION APN positivity may thus constitute a regional rather than systemic manifestation. The TNM staging based on the number of metastatic lymph nodes seems to be more reasonable than the regional lymph node classification method.

Abstract
Dehiscence of colorectal anastomosis is a serious complication that is associated with increased mortality, impaired functional and oncological outcomes. The hypothesis was that anastomosis reinforcement and vacuum trans-anal drainage could eliminate some risk factors, such as mechanically stapled anastomosis instability and local infection. Patients with rectal cancer within 10 cm of the anal verge and low anterior resection with double-stapled technique were included consecutively. A stapler anastomosis was supplemented by trans-anal reinforcement and vacuum drainage using a povidone-iodine-soaked sponge. Modified reinforcement using a circular mucosa plication was developed and used. Patients were followed up by postoperative endoscopy and outcomes were acute leak rate, morbidity, and diversion rate. The procedure was successfully completed in 52 from 54 patients during time period January 2019–October 2020. The mean age of patients was 61 years (lower–upper quartiles 54–69 years). There were 38/52 (73%) males and 14/52 (27%) females; the neoadjuvant radiotherapy was indicated in a group of patients in 24/52 (46%). The mean level of anastomosis was 3.8 cm (lower–upper quartiles 3.00–4.88 cm). The overall morbidity was 32.6% (17/52) and Clavien–Dindo complications ≥ 3 grade appeared in 3/52 (5.7%) patients. No loss of anastomosis was recorded and no patient died postoperatively. The symptomatic anastomotic leak was recorded in 2 (3.8%) patients and asymptomatic blind fistula was recorded in one patient 1/52 (1.9%). Diversion ileostomy was created in 1/52 patient (1.9%). Reinforcement of double-stapled anastomosis using a circular mucosa plication with combination of vacuum povidone-iodine-soaked sponge drainage led to a low acute leak and diversion rate. This pilot study requires further investigation. Registered at ClinicalTrials.gov.: Trial registration number is NCT04735107, date of registration February 2, 2021, registered retrospectively.

Abstract
Background Preservation of the left colic artery in low-tie (LT) of inferior mesenteric artery remains controversial compared to high-tie (HT) in the colon and rectal cancers, for lymph node dissection, anastomotic leakage, and oncological outcome. This cohort study aims to analyze short- and long-term outcomes of laparoscopic anterior resections in LT vs HT for rectal cancers. Methods We analyzed a cohort of laparoscopic AR for RC from 2013 to 2016 at Renji Hospital, Shanghai, China. Short- and long-term outcome in LT vs HT group were compared for clinico-demographic characteristics, operative-time, lymph node dissection, short-term 30-day outcome, and long-term 3- and 5-year overall survival as well as disease-free survival. The x2, t-test, and logistic regressions analysis were used and p<0.05 was considered significant. Results The cohort consisted of 614 laparoscopic AR with LT (236) and HT (378). The clinicodemographic characteristics were comparable among the groups. The surgery took longer in LT. The yield of LND was similar. Leakage occurred in 12.21% (n=75). Leakage was fewer in LT than HT, 8.89% vs 14.28%, p=0.047. The postoperative severe complications were higher in HT. The 30-day mortality was nil. The long-term 3- and 5-year overall survival and disease-free survival were similar in LT and HT. Conclusion The LT with preservation of left colic artery had similar lymph node yield, but lower leakage and complications than HT in laparoscopic anterior resections for rectal cancers. The long-term 3- and 5-year overall and disease-free survival were similar in the two groups.

High ligation of the inferior mesenteric artery and anastomotic leakage in anterior resection for rectal cancer: a systematic review and meta-analysis of randomized controlled trial studies. Colorectal Dis 2021; 23:614-624. [PMID: 33131205 DOI: 10.1111/codi.15419] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Revised: 10/06/2020] [Accepted: 10/27/2020] [Indexed: 02/08/2023]
Abstract
AIM Surgeons have concerns whether high ligation (HL) of the inferior mesenteric artery (IMA) increases the incidence of anastomotic leakage (AL). This meta-analysis aimed to evaluate the influence of HL of the IMA on AL compared with low ligation (LL). METHODS PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov databases were searched. Randomized controlled trial studies that compared HL with LL of the IMA in anterior resection for rectal cancer and reported AL outcomes were eligible for inclusion. The odds ratios and mean differences were analysed by a random-effects model. Trial sequential analysis was performed to minimize the risk of random errors. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of evidence for outcomes. RESULTS Of the 531 records screened, five randomized controlled trials with 779 patients were selected for analysis. The pooled incidence of AL was 12.1% (95% Cl 7.77-18.26) in the HL group and 9.7% (95% Cl 5.79-15.82) in the LL group (OR 1.20, 95% CI 0.77-1.87, P = 0.42). In trial sequential analysis, the cumulative Z-score curve exceeded the futility boundary, although the required information size of 1060 had not been reached. The quality of evidence was judged to be high according to the GRADE approach. CONCLUSIONS This meta-analysis shows that HL of the IMA does not increase the incidence of AL in anterior resection for rectal cancer.

Abstract
Background There is uncertainty in the literature about preserving the left colic artery (LCA) during low anterior resection for rectal cancer. We analyzed the effect of preserving the LCA on long-term oncological outcomes. Methods We retrospectively collected clinicopathological and follow-up details of patients who underwent low anterior resection for rectal cancer in the General Surgery Department of Guangdong Provincial People’s Hospital, from January 2014 to December 2015. Cases were divided into low ligation (LL), LCA preserved, or high ligation (HL), LCA not preserved, of the inferior mesenteric artery. The 5-year overall survival (OS) and disease-free survival (DFS) rates were compared between the two groups. Results Altogether, there were 221 and 295 cases in the LL group and HL groups, respectively. Operating time in the LL group was significantly longer than in the HL group (224.7 vs. 211.7 min, p = 0.039). Postoperative 30-day mortality, early complications including anastomotic leakage showed no significant differences between the LL and HL groups (postoperative 30-day mortality, 0.9% LL, 1.4% HL, p = 0.884; early complications, 41.2% LL, 38.3% HL, p = 0.509; anastomotic leakage 8.6% LL, 13.2% HL, p = 0.100). The median follow-up periods were 51.4 (7–61) months in the LL group and 51.2 (8–61) months in the HL group. During follow-up, the percentages of patients who died, had local recurrence, or had metastases were 39.8, 7.7, and 38.5%, respectively, in the LL group and 39, 8.5, and 40%, respectively, in the HL group; these differences were not significant (all p > 0.05). The 5-year OS and DFS were 69.6 and 59.6% in the LL group, respectively, and 69.1 and 56.2% in the HL group, respectively; these differences were not significant (all p > 0.05). After stratification by tumor-node-metastasis stage, the difference between the 5-year OS and DFS for stages I, II, and III cancer were not significant (all p > 0.05). Conclusions The long-term oncological outcomes of LL group are comparable with HL group. LL cannot be supported due to the absence of lower complication rates and the longer operating times.

Abstract
Background The aim was to study the clinical significance in the preservation of the left colic artery (LCA) and superior rectal artery (SRA) for the laparoscopic resection of sigmoid colon cancer (SCC). Patients and Methods A total of 316 patients with SCC were divided into two groups. Group A received D3 resection with preservation of LCA and SRA, whereas Group B ligatured artery at the root of the inferior mesenteric artery. The operation time, number of resected lymph nodes, blood loss and anastomotic leakage rate were compared. Results In Group A, the average operation time was 283.02 ± 51.48 min, the average blood loss was 111.81 ± 77.08 ml and the average lymph node dissection was 14.8 ± 7.7. There was no statistical significance in blood loss and number of resected lymph nodes between Group A and B (P > 0.05). Longer operating time were observed in Group A as compared to Group B (P < 0.05). The anastomotic leakage rate had statistical significance between these two groups (P < 0.05). Conclusions Preservation of LCA and SRA was safe and feasible for the laparoscopic surgery of SCC, which could reduce anastomotic leakage rate.

[PMID: 32900608 DOI: 10.1016/j.ejso.2020.07.044] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2020] [Revised: 07/17/2020] [Accepted: 07/30/2020] [Indexed: 01/18/2023] Open
Abstract
BACKGROUND Anastomotic leakage (AL) is a severe complication of low anterior resection (LAR) for rectal cancer, and effective prevention is urgently needed. In the robotic era, this study aimed to explore the role of innovative techniques in preventing AL in rectal cancer patients undergoing robotic LAR. METHODS From May 2012 to May 2017, a total of 601 patients underwent robotic LAR, with 191 patients participated as control subjects (non-PST group) and 410 patients are subjected to a trinity technique (PST group). The AL rate, short-term and long-term outcomes are analyzed and compared. RESULTS The overall rate of AL was 6.8% out of 601 patients, with Grade B at 5.7% and Grade C at 1.1%, using the ISREC grading system. The PST group presented lower incidence of both overall AL (5.1% vs 10.5%, P = 0.015) and major AL (0.2% vs 3.2%, P = 0.005), when compared with the non-PST group, respectively. Furthermore, the PST group had similar surgical complications (17.3% vs 20.9%, P = 0.286), while with lower re-hospitalization rate (2.7% vs 6.3%, P = 0.038) and reoperation rate (0.2% vs 4.2%, P = 0.001), compared with the non-PST group, respectively. Short-term recovery and long-term oncological outcomes were not significant in the two groups. By multivariate logistic regression models, the risk factors of AL of robotic LAR are confirmed as non-PST technique, estimated blood loss ≥100 mL, anastomosis from anal verge <5 cm, and distal resection margin from tumor <2 cm. CONCLUSIONS The innovative PST technique may shed light on an effective method for preventing occurrence of AL in robotic LAR.

Meta-analysis and Trial Sequential Analysis of Randomized Controlled Trials Comparing High and Low Ligation of the Inferior Mesenteric Artery in Rectal Cancer Surgery. Dis Colon Rectum 2020; 63:988-999. [PMID: 32243350 DOI: 10.1097/dcr.0000000000001693] [Citation(s) in RCA: 43] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/12/2022]
Abstract
BACKGROUND Despite ongoing debates, there is still no consensus regarding where to divide the inferior mesenteric artery for oncological reasons in rectal cancer: at its origin from the aorta (high ligation) or distal to the origin of the left colic artery (low ligation). OBJECTIVES The purpose of this study was to compare the outcomes of high and low ligation of the inferior mesenteric artery in rectal cancer surgery. DATA SOURCES MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry, ClinicalTrials.gov, and ISRCTN Register were searched. STUDY SELECTION andomized controlled trials investigating outcomes of curative anterior resection in patients with cancer of the rectum were included. INTERVENTIONS High ligation of the inferior mesenteric artery was compared with low ligation technique. MAIN OUTCOME MEASURES We measured the total number of lymph nodes harvested, anastomotic leak, postoperative complications, postoperative mortality, operative time, intraoperative blood loss, conversion to open surgery, overall survival, and disease-free survival. RESULTS Analysis of 1102 patients from 8 trials suggested no difference between high and low ligation of the inferior mesenteric artery in terms of total number of lymph nodes harvested (mean difference = -0.87; p = 0.26), anastomotic leak (OR = 1.39; p = 0.15), postoperative complications (OR = 1.39; p = 0.78), postoperative mortality (risk difference = -0.00; p = 0.48), operative time (mean difference = -1.99; p = 0.79), intraoperative blood loss (mean difference = -2.28; p = 0.77), conversion to open surgery (risk difference = 0.01; p = 0.48), 5-year overall survival (OR = 0.76; p = 0.32), 5-year disease-free survival (OR = 0.88; p = 0.58), overall survival at maximum follow up (OR = 0.80; p = 0.43), and disease-free survival at maximum follow-up (OR = 0.83; p = 0.35). LIMITATIONS Limited data were available on functional and long-term survival outcomes. CONCLUSIONS There is no difference between high and low ligation of the inferior mesenteric artery in terms of oncological outcomes or postoperative morbidity and mortality. The available evidence is subject to potential confounding by the use of neoadjuvant therapy, adjuvant therapy, disease stage, location of tumor, and use of protective stoma. Functional outcomes including postoperative bowel, urinary and sexual function, and long-term survival outcomes should be the outcome of study in future trials.

Clinical Effect of Preservation or Nonpreservation of Left Colic Artery in Total Mesorectal Excision under Laparoscopy: A Meta-analysis. Gastroenterol Res Pract 2020; 2020:1958573. [PMID: 32565778 PMCID: PMC7260651 DOI: 10.1155/2020/1958573] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/31/2019] [Accepted: 03/31/2020] [Indexed: 11/30/2022] Open
Abstract
Background and Aims To investigate the clinical effect of preservation or nonpreservation of the left colic artery (LCA) in total mesorectal excision (TME) under laparoscopy. Methods The words, like “rectal cancer,” “left colonic artery,” and “laparoscopy,” were used as the retrieval terms, and the keyword retrieval method was adopted. The retrieval period was set as from January 1, 2013, to June 1, 2018. We searched databases including PubMed, Web of Science, and China National Knowledge Infrastructure (CNKI) to collect randomized and controlled trials which compared the effect of preservation or nonpreservation of the LCA in TME under laparoscopy. Two researchers independently carried out literature screening, data extraction, and literature quality evaluation; Review Manager 5.3 was used for the meta-analysis. Results Seven studies including 1467 cases were identified for the meta-analysis. As showed by the meta-analysis, compared with the LCA nonpreservation group, the LCA preservation group had significantly reduced incidence of anastomotic leakage (OR = 0.44, CI = [0.30, 0.65], P < 0.0001) and postoperative urinary and sexual dysfunction (OR = 0.26, CI = [0.09, 0.78], P = 0.02) and significantly shorter time for intestinal function recovery (WMD = −0.26, CI = [−0.41, −0.11], P = 0.0008). There were no significant differences between the two groups in the duration of surgery, blood loss, number of dissected lymph nodes, or postoperative hospital stay. Conclusions From the results, the LCA preservation group seems to achieve comparable success with acceptable safety outcomes. Therefore, this surgical method can be recommended in the clinical practice.

Abstract
BACKGROUND For laparoscopic rectal cancer surgery, the inferior mesenteric artery (IMA) can be ligated at its origin from the aorta [high ligation (HL)] or distally to the origin of the left colic artery [low ligation (LL)]. Whether different ligation levels are related to different postoperative complications, operation time, and lymph node yield remains controversial. Therefore, we designed this study to determine the effects of different ligation levels in rectal cancer surgery. AIM To investigate the operative results following HL and LL of the IMA in rectal cancer patients. METHODS From January 2017 to July 2019, this retrospective cohort study collected information from 462 consecutive rectal cancer patients. According to the ligation level, 235 patients were assigned to the HL group while 227 patients were assigned to the LL group. Data regarding the clinical characteristics, surgical characteristics and complications, pathological outcomes and postoperative recovery were obtained and compared between the two groups. A multivariate logistic regression analysis was performed to evaluate the possible risk factors for anastomotic leakage (AL). RESULTS Compared to the HL group, the LL group had a significantly lower AL rate, with 6 (2.8%) cases in the LL group and 24 (11.0%) cases in the HL group (P = 0.001). The HL group also had a higher diverting stoma rate (16.5% vs 7.5%, P = 0.003). A multivariate logistic regression analysis was subsequently performed to adjust for the confounding factors and confirmed that HL (OR = 3.599; 95%CI: 1.374-9.425; P = 0.009), tumor located below the peritoneal reflection (OR = 2.751; 95%CI: 0.772-3.985; P = 0.031) and age (≥ 65 years) (OR = 2.494; 95%CI: 1.080-5.760; P = 0.032) were risk factors for AL. There were no differences in terms of patient demographics, pathological outcomes, lymph nodes harvested, blood loss, hospital stay and urinary function (P > 0.05). CONCLUSION In rectal cancer surgery, LL should be the preferred method, as it has a lower AL and diverting stoma rate.

Abstract
BACKGROUND To retrospectively evaluate the feasibility and safety of intraoperative assessment of bowel perfusion in totally laparoscopic surgery for colon cancer using indocyanine green fluorescence imaging (IGFI). METHODS From October 2017 to June 2019, consecutive patients with colon cancer who underwent totally laparoscopic surgery were enrolled retrospectively and grouped into the IGFI group (n = 84) and control group (n = 105). In the IGFI group, indocyanine green (ICG) was injected intravenously, and the bowel perfusion was observed using a fluorescence camera system prior to and after completion of the anastomosis. RESULTS The two groups were demographically comparable. The IGFI group exhibited a significantly shorter operative time (p = 0.0374) while intraoperative blood loss did not significantly differ among the groups (p = 0.062). In the IGFI group, average time to perfusion fluorescence was 48.4 ± 14.0 s after ICG injection, and four patients (4.8%) were required to choose a more proximal point of resection due to the lack of adequate fluorescence at the point previously selected. There were no differences in terms of pathological outcomes, postoperative recovery and the postoperative complication rates between the groups (p>0.05). CONCLUSION IGFI shows promise as a safe and feasible tool to assess bowel perfusion during a totally laparoscopic surgery for colon cancer and may reduce the operative time.

Abstract
Laparoscopic radical resection is standard treatment for resectable rectal cancer. However, whether high or low inferior mesenteric artery (IMA) ligation should be performed remains controversial. This retrospective cohort study compared the advantages and disadvantages of low vs high IMA ligation in patients undergoing laparoscopic total mesorectal excision for rectal cancer.Rectal cancer patients (n = 322) undergoing total mesorectal excision at our institution in 2010 to 17 were enrolled; 174 underwent high IMA ligation group and 148 low IMA ligation (LIMAL group). Baseline data on patients, operative indices, economic indices, pathology findings, perioperative complications, and survival in the 2 groups were analyzed retrospectively.The low IMA ligation group had significantly higher anus retention ratio (P = .022), shorter hospital stay (P = .025), lower medical expenses (P = .032), fewer cases of anastomotic leakage (P = .023) and anastomotic stricture (P < .001), and lower incidence of postoperative genitourinary dysfunction (P = .003). Cox regression analysis indicated that local recurrence, distant metastasis, tumor differentiation, and tumor-node-metastasis stage were independently associated with survival.Low ligation of the IMA during laparoscopic radical resection of rectal cancer appears to be associated with a lower risks for anastomotic leakage, anastomotic stricture, and genitourinary dysfunction, a shorter hospital stay, and lower costs. In contrast, the rate of lymph node harvest, tumor recurrence rate, metastasis, or mortality was not found to be related with the level of IMA ligation.

Abstract
BACKGROUND It is important for lymph node dissection around the inferior mesenteric artery (IMA) with preservation of the left colic artery (LCA) to be aware of the track and the length of the LCA. We aimed to investigate the branching pattern and trajectory of LCA and measure the distances from the root of the IMA to the origin of the LCA (D mm) and from the origin of LCA to intersection of LCA and IMV (d mm) during laparoscopic left-sided colorectal operations. METHODS We analyzed 106 patients who underwent laparoscope-assisted left-side colorectal surgery during laparoscopic surgery. The branching patterns among the IMA, LCA, and sigmoidal trunk were evaluated; the trajectory of LCA was examined; the D mm and d mm were measured using a length of silk in the surgical operation. RESULTS In 59.5% patients, the LCA arose independently from the sigmoidal trunk (type A); in 8.5% patients, the LCA and sigmoidal trunk arose from the IMA at the same point (type B); in 29.2% patients, the LCA and sigmoidal trunk had a common trunk (type C); the LCA did not exist in 2.8% (type D).The D mm and d mm for all cases ranged from 15.0 to 65.3 mm (median, 43.1 mm) and from 20.3 to 46.2 mm (median, 34.8 mm), respectively. 74.8% of the LCA went straight upper left and upward to proximal part of descending colon (type I), 25.2% went to the lower left at first, then turned to travel straight upward to proximal part of descending colon (type II). CONCLUSION This study showed the anatomic variations of LCA during laparoscopic left-sided colorectal operation, which would help surgeons safely perform laparoscopic surgery in the left-side colon and rectum.

Abstract
Purpose Colon perfusion status is one of the most important factors for the determination of postoperative anastomotic complications. Colonic hypoperfusion can be induced by inferior mesenteric artery (IMA) ligation in some patients. This study aimed to evaluate atherosclerotic risk assessment and vascular parameters of CT angiography as predictors of colonic hypoperfusion. Methods This prospective study was conducted at a tertiary referral hospital and included 46 rectosigmoid colon cancer patients undergoing laparoscopic anterior resection between August 2013 to July 2014. Atherosclerotic risk scores were assessed using the Framingham cardiovascular risk score system. The IMA length, branching pattern, atherosclerotic calcification, and intermesenteric artery and mesenteric vascular diameters were evaluated using CT angiography. Mesenteric marginal artery pressures were measured before and after IMA clamping. The mean arterial pressure (MAP) index was calculated by dividing the mesenteric marginal MAP into the systemic MAP to determine the mesenteric hypoperfusion status after IMA clamping. A critically low MAP index was defined as <0.4. Results Critically low MAP index (<0.4) was observed in 6 cases (13.0%) after IMA clamping. Atherosclerotic calcification of the IMA and superior mesenteric artery occurred in 11 (23.9%) and 5 patients (10.9%), respectively. Low MAP index was associated with high atherosclerotic risk score and short IMA length, rather than atherosclerotic calcification and other vascular parameters of the major mesenteric arteries. Multivariate analysis indicated that high atherosclerotic risk and short IMA length were independent predictors of critically low MAP index. Conclusion Atherosclerotic risk assessment and IMA length were useful predictors of the mesenteric hypoperfusion status following IMA ligation during laparoscopic rectosigmoid colon surgery.

Abstract
PURPOSE The aim of this meta-analysis was to compare high inferior mesenteric artery (IMA) ligation (HL) with low IMA ligation (LL) for the treatment of colorectal cancer and to evaluate the lymph node yield, survival benefit, and safety of these surgeries. METHODS PubMed, Embase, Cochrane Library, Web of Science, and China Biomedical Literature Database (CBM) were systematically searched for relevant articles that compared HL and LL for sigmoid or rectal cancer. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) for dichotomous outcomes and the weighted mean difference (WMD) for continuous outcomes. RESULTS In total, 30 studies were included in this analysis. There were significantly higher odds of anastomotic leakage and urethral dysfunction in patients treated with HL compared to those treated with LL (OR = 1.29; 95% CI = 1.08 to 1.55; OR = 2.45; 95% CI = 1.39 to 4.33, respectively). There were no significant differences between the groups in terms of the total number of harvested lymph nodes, the number of harvested lymph nodes around root of the IMA, local recurrence rate, and operation time. Further, no statistically significant group differences in 5-year overall survival rates and 5-year disease-free survival rates were detected among all patients nor among subgroups of stage II patients and stage III patients, respectively. CONCLUSIONS LL can achieve equivalent lymph node yield to HL, and both procedures have similar survival benefits. However, LL is associated with a lower incidence of leakage and urethral dysfunction. Thus, LL is recommended for colorectal cancer surgery.

Abstract
BACKGROUND It remains unclear whether or not preservation of the left colic artery (LCA) for colorectal cancer surgery. The objective of this updated systematic review and meta-analysis is to evaluate the current scientific evidence of LCA non-preservation versus LCA preservation in colorectal cancer surgery. METHODS A systematic search was conducted in the Medline, Embase, PubMed, Cochrane Library, ClinicalTrials, Web of Science, China National Knowledge Infrastructure and Chinese BioMedical Literature Database, and reference without limits. Quality of studies was evaluated by using the Newcastle-Ottawa scale and the Cochrane Collaboration's tool for assessing the risk of bias. Effective sizes were pooled under a random- or fixed-effects model. The funnel plot was used to assess the publication bias. The outcomes of interest were oncologic consideration including the number of apical lymph nodes, overall recurrence, 5-years overall survival, and 5-years disease-free survival (DFS); safety consideration including overall 30-day postoperative morbidity and overall 30-day postoperative mortality; anatomic consideration including anastomotic circulation, anastomotic leakage, urogenital, and defaecatory dysfunction. RESULTS Twenty-four studies including 4 randomized controlled trials (RCTs) and 20 cohort studies with a total of 8456 patients (4058 patients underwent LCA non-preservation surgery vs 4398 patients underwent LCA preservation surgery) were enrolled in this meta-analysis. The preservation of LCA was associated with significantly less anastomotic leakage (odds ratio 1.23, 95% confidence interval 1.02-1.48, P = .03). In term of sexual dysfunction, urinary retention, the number of apical lymph nodes, and long-term oncologic outcomes, there were no significant differences between the LCA non-preservation and LCA preservation group. It was hard to draw definitive conclusions on other outcomes including operation time, blood loss, the first postoperative exhaust time, and perioperative morbidity and mortality for insufficient data and highly significant heterogeneity among studies. CONCLUSIONS The pooled data provided evidence to support the LCA preservation preferred over LCA non-preservation in anastomotic leakage. Future more large-volume, well-designed RCTs with extensive follow-up are needed to draw a definitive conclusion on this dilemma.

Abstract
The aim of the present meta-analysis compared left colic artery (LCA) preservation with non-preservation in laparoscopic resection of rectal cancer in terms of feasibility, efficacy and safety. The PubMed, Ovid, Embase, Web of Science, CBM, CNKI, VIP and WanFang Data databases were searched prior to June 2017 for studies comparing LCA preservation and non-preservation in laparoscopic resection for rectal cancer. Two researchers screened the literature independently, extracted the data and evaluated the risk of bias. The study was performed using RevMan 5.3 software for meta-analysis. A total of 10 studies comparing LCA preservation and non-preservation in laparoscopic resection for rectal cancer were selected for this meta-analysis, with a combined study population of 1,471 patients. The results of the meta-analysis demonstrated that, when comparing LCA preservation with non-preservation in laparoscopic resection for rectal cancer, there were significant differences between the two groups in terms of operative time (P<0.01), estimated blood loss (P<0.01), percentage of neostomy (P<0.01), the number of retrieved lymph nodes (P<0.01), time to first postoperative exhaust (P<0.01) and amount of anastomotic leakage (P<0.01). However, there were no significant differences in postoperative hospital stay (P=0.28), incidence of recurrence (P=0.73) and incidence of metastasis (P=0.52). Therefore, compared with LCA non-preservation, patients in whom the LCA was preserved during laparoscopic resection for rectal cancer had a better prognosis. However, there was no difference in recurrence or metastasis between the two groups. Although the operative time and estimated blood loss were increased with LCA preservation, these may be reduced with improving proficiency of the operating surgeons. The conclusions of the present study require verification by larger samples and high-quality randomized controlled trials.

Quantitative analysis of colon perfusion pattern using indocyanine green (ICG) angiography in laparoscopic colorectal surgery. Surg Endosc 2018; 33:1640-1649. [PMID: 30203201 PMCID: PMC6484815 DOI: 10.1007/s00464-018-6439-y] [Citation(s) in RCA: 117] [Impact Index Per Article: 19.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2018] [Accepted: 09/05/2018] [Indexed: 12/17/2022]
Abstract
Purpose This study aimed to quantitatively evaluate colon perfusion patterns using indocyanine green (ICG) angiography to find the most reliable predictive factor of anastomotic complications after laparoscopic colorectal surgery. Methods Laparoscopic fluorescence imaging was applied to colorectal cancer patients (n = 86) from July 2015 to December 2017. ICG (0.25 mg/kg) was slowly injected into peripheral blood vessels, and the fluorescence intensity of colonic flow was measured sequentially, producing perfusion graphs using a video analysis and modeling tool. Colon perfusion patterns were categorized as either fast, moderate, or slow based on their fluorescence slope, T1/2MAX and time ratio (TR = T1/2MAX/TMAX). Clinical factors and quantitative perfusion factors were analyzed to identify predictors for anastomotic complications. Results The mean age of patients was 65.4 years, and the male-to-female ratio was 63:23. Their operations were laparoscopic low anterior resection (55 cases) and anterior resection (31 cases). The incidence of anastomotic complication was 7%, including colonic necrosis (n = 1), anastomotic leak (n = 3), delayed pelvic abscess (n = 1), and delayed anastomotic dehiscence (n = 1). Based on quantitative analysis, the fluorescence slope, T1/2MAX, and TR were related with anastomotic complications. The cut-off value of TR to categorize the perfusion pattern was determined to be 0.6, as shown by ROC curve analysis (AUC 0.929, P < 0.001). Slow perfusion (TR > 0.6) was independent factor for anastomotic complications in a logistic regression model (OR 130.84; 95% CI 6.45–2654.75; P = 0.002). Anastomotic complications were significantly correlated with the novel factor TR (> 0.6) as the most reliable predictor of perfusion and anastomotic complications. Conclusions Quantitative analysis of ICG perfusion patterns using T1/2MAX and TR can be applied to detect segments with poor perfusion, thereby reducing anastomotic complications during laparoscopic colorectal surgery.
