Abstract
Colorectal cancer is the third most common cancer in the world. Surgery is mandatory to treat patients with colorectal cancer. Can colorectal cancer be treated in laparoscopy? Scientific literature has validated the oncological quality of laparoscopic approach for the treatment of patients with colorectal cancer. Randomized non-inferiority trials with good remote control have answered positively to this long-debated question. Early as 1994, first publications demonstrated technical feasibility and compliance with oncological imperatives and, as far as short-term outcomes are concerned, there is no difference in terms of mortality and post-operative morbidity between open and minimally invasive surgical approaches, but only longer operating times at the beginning of the experience. Subsequently, from 2007 onwards, long-term results were published that demonstrated the absence of a significant difference regarding overall survival, disease-free survival, quality of life, local and distant recurrence rates between open and minimally invasive surgery. In this editorial, we aim to summarize the clinical and technical aspects which, even today, make the use of open surgery relevant and necessary in the treatment of patients with colorectal cancer.

Abstract
BACKGROUND Proficient surgical skills are essential for surgeons, making surgical training an important part of surgical education. The development of technology promotes the diversification of surgical training types. This study analyzes the changes in surgical training patterns from the perspective of bibliometrics, and applies the learning curves as a measure to demonstrate their teaching ability. METHOD Related papers were searched in the Web of Science database using the following formula: TS=[(training OR simulation) AND (learning curve) AND (surgical)]. Two researchers browsed the papers to ensure that the topics of articles were focused on the impact of surgical simulation training on the learning curve. CiteSpace, VOSviewer, and R packages were applied to analyze the publication trends, countries, authors, keywords, and references of selected articles. RESULT Ultimately, 2461 documents were screened and analyzed. The USA is the most productive and influential country in this field. Surgical endoscopy and other interventional techniques publish the most articles, while surgical endoscopy and other interventional techniques is the most cited journal. Aggarwal Rajesh is the most productive and influential author. Keyword and reference analyses reveal that laparoscopic surgery, robotic surgery, virtue reality, and artificial intelligence were the hotspots in the field. CONCLUSION This study provided a global overview of the current state and future trend in the surgical education field. The study surmised the applicability of different surgical simulation types by comparing and analyzing the learning curves, which is helpful for the development of this field.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:107113. [PMID: 37857102 DOI: 10.1016/j.ejso.2023.107113] [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: 07/24/2023] [Revised: 09/26/2023] [Accepted: 10/08/2023] [Indexed: 10/21/2023]
Abstract
BACKGROUND Benign anastomotic strictures (BAS) significantly impact patients' quality of life and long-term prognosis. However, the current clinical practice lacks accurate tools for predicting BAS. This study aimed to develop a machine-learning model to predict BAS in patients with rectal cancer who have undergone anterior resection. METHODS Data from 1973 patients who underwent anterior resection for rectal cancer were collected. Multiple machine learning classification models were integrated to analyze the data and identify the optimal model. Model performance was evaluated using receiver operator characteristic (ROC) curves, decision curve analysis (DCA), and calibration curves. The Shapley Additive exPlanation (SHAP) algorithm was utilized to assess the impact of various clinical characteristics on the optimal model to enhance the interpretability of the model results. RESULTS A total of 10 clinical features were considered in constructing the machine learning model. The model evaluation results indicated that the random forest (RF)model was optimal, with the area under the test set curve (AUC: 0.888, 95% CI: 0.810-0.965), accuracy: 0.792, sensitivity: 0.846, specificity: 0.791. The SHAP algorithm analysis identified prophylactic ileostomy, operative time, and anastomotic leakage as significant contributing factors influencing the predictions of the RF model. CONCLUSION We developed a robust machine-learning model and user-friendly online prediction tool for predicting BAS following anterior resection of rectal cancer. This tool offers a potential foundation for BAS prevention and aids clinical practice by enabling more efficient disease management and precise medical interventions.

Abstract
PURPOSE Whether epidural anesthesia leads to further improvement in the postoperative course of colorectal procedures is under discussion. The aim of this study was to evaluate the effects of minimally invasive colorectal oncological interventions without epidural anesthesia (EDA). METHODS This retrospective data analysis included the clinical data of all patients who underwent minimally invasive oncological colorectal resection at our clinic between January 2013 and April 2019. Of 385 patients who met the inclusion criteria, 183 (group I; 47.5% of 385) received EDA, and 202 (group II; 52.5% of 385) received transversus abdominis plane block instead. The relevant target parameters were evaluated and compared between the groups. The postoperative complications were graded according to the Clavien-Dindo classification. RESULTS The patients in group I (n=183; women, 77; men, 106; age 66.8 years) were younger (p=0.0035), received a urinary catheter more often (99.5% versus [vs.] 28.2% p<0.001), required longer, more frequent arterenol treatment (1.1 vs. 0.6 days; p<0.001), and had a longer intermediate care unit stay than those in group II (2.8 vs. 1.1 days; p<0.001). Postoperative pain levels were not significantly different between the groups (p=0.078). The patients in group I were able to ambulate later than those in group II (4 vs. 2 days; p<0.001). The difference in the postoperative day of the first defecation was not significant between the groups (p=0.236). The incidence of postoperative complications such as bleeding (p=0.396), anastomotic leaks (p=0.113), and wound infections (p=0.641) did not differ between the groups. The patients in group I had significantly longer hospital stays than those in group II (12.2 vs. 9.4 days; p<0.001). CONCLUSION EDA can be safely omitted from elective minimally invasive colorectal resections, and its omission is not accompanied by any relevant disadvantages to the patient.

Abstract
PURPOSE The purpose of this study was to investigate the effect of laparoscopic left colectomy (LLC) and laparoscopic sigmoidectomy (LSD) on short-term outcomes and prognosis of sigmoid colon cancer (SCC) patients using propensity score matching (PSM). METHODS In this retrospective study, the SCC patients who underwent LLC or LSD surgery were collected from a single clinical center from Jan 2011 to Dec 2019. Short-term outcomes and prognosis were compared between patients who received LSD surgery and LLC surgery. RESULTS A total of 356 patients were included in this study. After 1:1 PSM analysis, there were 50 patients who underwent LLC surgery and 50 patients who underwent LSD surgery left in this study. No significant difference was found in baseline characteristics after PSM (P > .05). In comparison with the LLC surgery group, the LSD surgery group had shorter operation time (P = .003) after PSM. Moreover, the surgical procedure was not an independent predictor for overall survival (OS) (P = .918, 95% CI = .333-2.688) and disease-free survival DFS (P = .730, 95% CI = .335-2.150), but age (OS: P = .009, 95% CI = 1.010-1.075; DFS: P = .014, 95% CI = 1.007-1.061) and tumor stage (OS: P = .004, 95% CI = 1.302-3.844; DFS: P < .01, 95% CI = 1.572-4.171) were the independent risk factors for OS and DFS in SCC patients. CONCLUSION There was no significant difference between the two surgical procedures for prognosis of SCC patients. However, the possible reasons for changing the surgical procedures should be cautious by surgeons.

Abstract
BACKGROUND The aim of this study was to investigate the influence of obesity and the usefulness of a preoperative weight loss program (PWLP) for obese patients undergoing laparoscopic colorectal resection (LCR). METHODS Study 1: 392 patients who underwent LCR for colorectal cancer were divided into two groups: those with a body mass index (BMI) ≥25 kg/m2 (n = 113) and those with a BMI <25 kg/m2 (n = 279). The influence of BMI on LCR was investigated. Study 2: Patients with a BMI ≥28 kg/m2 who were scheduled to undergo LCR (n = 7, mean body weight 87.0 kg, mean BMI 33.9 kg/m2) undertook a PWLP including caloric restriction and exercise for 29.6 (15-70) days. The effects of this program were evaluated. RESULTS Study 1: The BMI ≥25 kg/m2 group had a prolongation of operation time and hospital stay than the BMI <25 kg/m2 group. Study 2: The patients achieved a mean weight loss of 6.9% (-6.0 kg). The mean visceral fat area was significantly decreased by 18.0%, whereas the skeletal muscle mass was unaffected. The PWLP group had a significantly lower prevalence of postoperative complications compared with the BMI ≥25 kg/m2 group. CONCLUSION Obesity affected the surgical outcomes in LCR. A PWLP may be useful for obese patients undergoing LCR.

Abstract
INTRODUCTION The number of laparoscopic liver resections undertaken has increased. However, lesions located postero-superiorly are difficult to access. This may be overcome by the novel use of trans-thoracic port(s). Methods for the safe and transparent introduction of new and modified surgical procedures are limited and a summary of these issues, for minimally invasive trans-thoracic liver resections (MITTLR), is lacking. This study aims to understand and summarize technique description, governance procedures, and reporting of outcomes for MITTLR. METHODS A systematic literature search to identify primary studies of all designs describing MITTLR was undertaken. How patients were selected for the new technique was examined. The technical components of MITTLR were identified and summarized to understand technique development over time. Governance arrangements (eg, Institutional Review Board approval) and steps taken to mitigate harm were recorded. Finally, specific outcomes reported across studies were documented. RESULTS Of 2067 screened articles, 16 were included reporting data from 145 patients and 6 countries. Selection criteria for patients was explicitly stated in 2 papers. No studies fully described the technique. Five papers reported ethical approval and 3 gave details of patient consent. No study reported on steps taken to mitigate harm.Technical outcomes were commonly reported, for example, blood loss (15/16 studies), operative time (15/16), and margin status (11/16). Information on patient-reported outcomes and costs were lacking. CONCLUSIONS Technical details and governance procedures were poorly described. Outcomes focussed on short term details alone. Transparency is needed for reporting the introduction of new surgical techniques to allow their safe dissemination.

Abstract
INTRODUCTION Clinical benefits of laparoscopic surgery are well established, but evidence for financial benefits is limited. This study aimed to compare the financial impact of the introduction of laparoscopic colorectal surgery. METHODS This study included patients who underwent colorectal surgery between January 2010 and 2015. We collected a range of financial data and divided the patients into 2 groups. Primary outcome was total cost defined by surgical-related costs. RESULTS A total of 1,246 patients were included, of which 440 surgeries were performed laparoscopically. The total median cost of laparoscopy was higher compared to open surgery (EUR 4,665 vs. EUR 4,268, p = 0.001). Laparoscopy was associated with higher equipment costs (EUR 857 vs. EUR 232, p < 0.001), longer operating time (3.2 vs. 2.5 hours, p < 0.001), and more readmissions (10.9 vs. 8.5%, p < 0.001). However, after adjusting for heterogeneity, no difference was found in total cost. Surgical-related costs were counterbalanced by lower costs associated with shorter median hospital stay (6 vs. 9 days, p < 0.001), less morbidity (37.3 vs. 55.1%, p < 0.001), and less mortality (1.8 vs. 5.6%, p = 0.013) for laparoscopy. CONCLUSION During the introduction of laparoscopy for colorectal surgery, no significant differences were found in total cost between laparoscopic and open colorectal surgery. However, favorable postoperative outcomes were achieved with laparoscopic surgery.

Abstract
Background Intestinal complications are a major cause of morbidity after colorectal cancer surgery. This study aimed to develop an effective nomogram for predicting risk of intestinal complications following colorectal cancer surgery. Material/Methods We retrospectively analyzed 1876 patients who underwent colorectal cancer surgery at Yangpu and Zhuji hospitals from January 2013 to October 2018. Intestinal complications were defined as intestinal obstruction, leakage or bleeding, or peritonitis within 30 days after surgery. A logistic regression model was used to identify the risk factors associated with postoperative intestinal complications, and a nomogram for intestinal complications was established. The predictive accuracy of the nomogram was assessed using area under the receiver operating characteristic curve (AUC) and calibration plot. Results A total of 164 patients (8.7%) developed intestinal complications after colorectal cancer surgery; 35 (21.3%) of whom died in the postoperative period. Multivariate logistic analysis showed that male gender, history of abdominal surgery, preoperative intestinal obstruction/perforation, metastatic cancer, and lower level of hemoglobin and prognostic nutrition index were independent risk factors (P<0.05 for all). A nomogram was then constructed, and it displayed good accuracy in predicting postoperative intestinal complications with an AUC of 0.76. The calibration plot also showed an excellent agreement between the predicted and observed probabilities. Conclusions We constructed a nomogram based on clinical variables, which could provide individual prediction of postoperative intestinal complications with good accuracy.

Abstract
Several studies have reported high rates of urogenital dysfunction after open and laparoscopic surgery for rectal cancer. Robotic surgery has several features that could facilitate identification and preservation of autonomic nerves. This manuscript aims to summarize the literature regarding urogenital function after robotic rectal cancer surgery and focus on technical aspects of nerve-sparing total mesorectal excision. Comprehensive searches were conducted through online databases. Selection criteria included: original articles assessing urinary and sexual function after robotic surgery of males and/or females with standardized questionnaires. A total of 16 articles were included in the review. Seven of the nine cohort studies evaluating male sexual function showed earlier recovery or better outcomes in patients operated with robotic techniques. Two studies did not find any statistically significant difference. Three out of four case series found no difference in sexual function scores measured preoperatively and after 1 year. Female sexual function was assessed in seven studies: two case series show no deterioration of at 1 year. Three comparative studies showed no difference between robotic and laparoscopic groups. Two randomized control trials showed different results in terms of male and female sexual functions with better preservation at 1 year in the robotic group in one and no difference in another. Urinary functions assessed in males and/or females in the 16 studies showed no statistically significant differences at long-term follow-up. At present, there is no evidence of superiority of robotic surgery for performing nerve-sparing rectal cancer surgery.

Abstract
BACKGROUND Laparoscopic colorectal surgery has a long learning curve. Using a modular-based training programme may shorten this. Concerns with laparoscopic surgery have been oncological compromise and poor surgical outcomes when training more junior surgeons. This study aimed to compare operative and oncological outcomes between trainees undergoing a mentored training programme and a consultant trainer. METHODS A prospective study of all elective laparoscopic colorectal resections was undertaken in a single institution. Operative and oncological outcomes were recorded. All trainees were mentored by a National Laparoscopic Trainer (Lapco), and results between trainer and trainees compared. RESULTS Three hundred cases were included, with 198 (66%) performed for cancer. The trainer undertook 199 (66%) of operations, whilst trainees performed 101 (34%). Anterior resection was the commonest operation (n = 124, 41%). There were no differences between trainer and trainees for the majority of surgical outcomes, including blood loss (p = 0.598), conversion to open (p = 0.113), anastomotic leak (p = 0.263), readmission (p = 1.000) and death rates (p = 0.549). Only length of stay (p = 0.034), stoma formation (p < 0.01) and operative duration (p = 0.007) were higher in the trainer cohort, reflecting the more complex cases undertaken. Overall, there were no significant differences in both short- and longer-term oncology outcomes according to the grade of operating surgeon, including lymph nodes in specimen, circumferential resection margin and 1- and 2-year radiological recurrence. CONCLUSION When a modular-based training system was combined with case selection, both clinical and histopathological outcomes following resectional laparoscopic colorectal surgery were similar between trainees and trainer. This should encourage the use of more training opportunities in laparoscopic colorectal surgery.

Abstract
BACKGROUND The use of laparoscopic surgery for colorectal cancer has become widespread recently. However, the safety and oncological outcomes of laparoscopic surgery for primary advanced colorectal cancer need extensive investigation. We analyzed the short- and long-term outcomes after laparoscopic multivisceral resection for primary colon cancer with suspected invasion of other organs at a single institution. METHODS Between January 2000 and December 2014, 118 patients underwent laparoscopic multivisceral resection for primary colon cancer invading or adhering to adjacent organs or structures; their short- and long-term outcomes were retrospectively evaluated. RESULTS The median operating time was 254 min (range 130-1051 min), and median blood loss was 48 ml (range 0-2777 ml). The overall conversion rate was 6.8%. The postoperative complication rate was 17.8%. The number of patients with R0 and R1 resection was 112 (94.9%) and 6 (5.1%), respectively. At a median follow-up period of 32 months (range 0-157 months), the local recurrence rate in patients who underwent R0 resection was 1.8%, while for R1 resection it was 66.7%. In multivariate analysis, R1 resection and LN metastases were found to be predictors of poor prognosis. The cancer-specific 5-year survival was 87% when R0 resection was achieved; within these, the 5-year survival rates for patients with stages II, III, and IV disease were 94, 81, and 40%, respectively. CONCLUSIONS Laparoscopic en bloc multivisceral resection for clinically suspected T4 colon cancer is a safe and feasible procedure for precisely selected patients, attaining satisfactory oncological outcomes when R0 resection is achieved.

Abstract
Purpose For locally advanced pathological T4 (pT4) colon cancer, the safety and feasibility of laparoscopic procedures remain controversial. Therefore, this study aimed to assess short-term and long-term outcomes and to identify the prognostic factors in laparoscopic surgery for pT4 colon cancer. Methods The study group included 130 patients who underwent laparoscopic radical resection for pT4 colon and rectosigmoid cancer from January 2004 through December 2012. The short-term outcomes, long-term outcomes, and prognostic factors in pT4 colon cancer were analyzed. Results The median operative time was 205 min, with a median blood loss of 10 ml. The conversion rate was 3.8%, and 13 patients (10.0%) had postoperative complications. The radial resection margin was positive in 1 patient (0.8%). The median follow-up time was 73 months. The 5-year overall survival (OS) and recurrence-free survival (RFS) were 77.2 and 63.5%, respectively. On a multivariate analysis, a male sex [hazard ratio (HR) 3.09, p < 0.001], lymph node ratio ≥ 0.06 (HR 2.35, p = 0.021), tumor diameter < 38 mm (HR 2.57, p = 0.007), and right-sided colon cancer (HR 2.11, p = 0.047) were significantly related to a poor OS. Conclusions These results suggest that laparoscopic surgery for pT4 colon cancer is safe and feasible, and the oncological outcomes are acceptable. Based on the present findings, select patients with locally advanced colon cancer should not be excluded from laparoscopic surgery.

Abstract
INTRODUCTION Colorectal cancer is the second most common cause of death from neoplastic disease in men and third in women of all ages. Globally, life expectancy is increasing, and consequently, an increasing number of operations are being performed on more elderly patients with the trend set to continue. Elderly patients are more likely to have cardiovascular and pulmonary comorbidities that are associated with increased peri-operative risk. They further tend to present with more locally advanced disease, more likely to obstruct or have disseminated disease. The aim of this review was to investigate the feasibility of laparoscopic colorectal resection in very elderly patients, and whether there are benefits over open surgery for colorectal cancer. METHODS A systematic literature search was performed on Medline, Pubmed, Embase and Google Scholar. All comparative studies evaluating patients undergoing laparoscopic versus open surgery for colorectal cancer in the patients population over 85 were included. The primary outcomes were 30-day mortality and 30-day overall morbidity. Secondary outcomes were operating time, time to oral diet, number of retrieved lymph nodes, blood loss and 5-year survival. RESULTS The search provided 1507 citations. Sixty-nine articles were retrieved for full text analysis, and only six retrospective studies met the inclusion criteria. Overall mortality for elective laparoscopic resection was 2.92% and morbidity 23%. No single study showed a significant difference between laparoscopic and open surgery for morbidity or mortality, but pooled data analysis demonstrated reduced morbidity in the laparoscopic group (p = 0.032). Patients undergoing laparoscopic surgery are more likely to have a shorter hospital stay and a shorter time to oral diet. CONCLUSION Elective laparoscopic resection for colorectal cancer in the over 85 age group is feasible and safe and offers similar advantages over open surgery to those demonstrated in patients of younger ages.

Risk Factors for Conversion and Morbidity During Initial Experience in Laparoscopic Proctectomies: a Retrospective Study. Indian J Surg 2017; 79:90-95. [PMID: 28442832 DOI: 10.1007/s12262-015-1426-1] [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: 08/25/2015] [Accepted: 12/23/2015] [Indexed: 10/22/2022] Open
Abstract
The aim of this study was to determine the predictable factors for conversion during laparoscopic proctectomies, and for postoperative morbidity, in order to assist in defining the best candidates of patients for initial experience in laparoscopic proctectomies for rectal adenocarcinoma. A retrospective analysis of consecutive patients who underwent laparoscopic rectal resection for rectal adenocarcinoma operated by a single surgeon, between 2005 and 2012, were performed. Predictive factors for conversion and for postoperative morbidity were analyzed using univariate and multivariate analysis. Sixty-nine patients were included. There were 35 (50.7 %) men with a median age of 53 years. Forty-seven patients had tumors located below 8 cm from the anal verge, and sphincter-preserving surgery was performed in 52 (75.4 %) patients. Thirty-four patients were operated in the early period (before 2009). Conversion rate was 17.4 %. In multivariate analysis, the independent predictive factors for conversion were time period (before 2009) (p = 0.007, Exp. 19.9; CI (95 %) 2.2-177.4) and tumors located 8 cm above the anal verge (p = 0.028, Exp. 5.23, CI (95 %) 1.2-22.8). Twenty-two patients (31.9 %) had a complicated postoperative course. Only male gender was associated with postoperative complications (p = 0.01, CI (95 %) 1.3-11.8). Our study showed that conversion rate is influenced by surgeon's experience, and height of the tumor and that male gender is a predisposing factor for a higher morbidity rate. These results suggest that women with low rectal tumors requiring colo-anal anastomosis or abdomino-perineal resection would be the best candidates for early surgeons' experience in laparoscopic proctectomies for rectal adenocarcinoma.

Abstract
AIM The relationship between obesity, body mass index (BMI) and laparoscopic colorectal resection is unclear. Our object was to assess systematically the available evidence to establish the influence of obesity and BMI on the outcome of laparoscopic colorectal resection. METHOD A search of PubMed/Medline databases was performed in May 2015 to identify all studies investigating the impact of BMI and obesity on elective laparoscopic colorectal resection performed for benign or malignant bowel disease. Clinical end-points examined included operation time, conversion rate to open surgery, postoperative complications including anastomotic leakage, length of hospital stay, readmission rate, reoperation rate and mortality. For patients who underwent an operation for cancer, the harvested number of lymph nodes and long-term oncological data were also examined. RESULTS Forty-five studies were analysed, the majority of which were level IV with only four level III (Oxford Centre for Evidence-based Medicine 2011) case-controlled studies. Thirty comparative studies containing 23 649 patients including 17 895 non-obese and 5754 obese showed no significant differences between the two groups with respect to intra-operative blood loss, overall postoperative morbidity, anastomotic leakage, reoperation rate, mortality and the number of retrieved lymph nodes in patients operated on for malignancy. Most studies, including 15 non-comparative studies, reported a longer operation time in patients who underwent a laparoscopic procedure with the BMI being an independent predictor in multivariate analyses for the operation time. CONCLUSION Laparoscopic colorectal resection is safe and technically and oncologically feasible in obese patients. These results, however, may vary outside of high volume centres of expertise.

Abstract
BACKGROUND Laparoscopic pancreaticoduodenectomy (LPD), an advanced minimally invasive technique, has demonstrated advantages to open pancreaticoduodenectomy (OPD). However, this complex procedure requires a relatively long training period to ensure technical proficiency. This study was therefore designed to analyze the learning curve for LPD. METHODS From October 2010 to September 2015, 63 standard pancreaticoduodenectomy procedures were to be performed laparoscopically by a single surgeon at the Department of Pancreatic Surgery, West China Hospital, Sichuan University, China. After applying the inclusion and exclusion criteria, a total of 57 patients were included in the study. Data for all the patients, including preoperative, intraoperative, and postoperative variables, were prospectively collected and analyzed. The learning curve for LPD was evaluated using both cumulative sum (CUSUM) and risk-adjusted CUSUM (RA-CUSUM) methods. All of the variables among the learning curve phases were compared. RESULTS Based on the CUSUM and the RA-CUSUM analyses, the learning curve for LPD was grouped into three phases: phase I was the initial learning period (cases 1-11), phase II represented the technical competence period (cases 12-38), and phase III was regarded as the challenging period (cases 39-57). The operative time, intraoperative blood loss, and postoperative ICU demand significantly decreased with the learning curve. More lymph nodes were collected after the initial learning period. There were no significant differences in terms of postoperative complications or the 30-day mortality among the three phases. More challenging cases were encountered in phase III. CONCLUSIONS According to this study, the learning curve for LPD consisted of three phases. Conservatively, to attain technical competence for performing LPD, a minimum of 40 cases are required for laparoscopic surgeons with a degree of laparoscopic experience.

Abstract
INTRODUCTION The utilization of laparoscopy in colorectal surgery is increasing. However, conversion to open surgery remains relatively high. OBJECTIVE We evaluated (1) conversion rates in laparoscopic colorectal surgery; (2) the outcomes of converted cases compared with successful laparoscopic and open colorectal operations; (3) predictive risk factors of conversion of laparoscopic colorectal surgery to open surgery. METHODS Using the National Inpatient Sample database, we examined the clinical data of patients who underwent colon and rectal resection from 2009 to 2010. Multivariate regression analysis was performed to identify factors predictive for conversion of laparoscopic to open operation. RESULTS A total of 207,311 patients underwent intended laparoscopic colorectal resection during this period. The conversion rate was 16.6 %. Considering resection type and pathology, the highest conversion rates were observed in proctectomy (31.4 %) and Crohn's disease (20.2 %). Using multivariate regression analysis, Crohn's disease (adjusted odds ratio [AOR], 2.80), prior abdominal surgery (AOR, 2.45), proctectomy (AOR, 2.42), malignant pathology (AOR, 1.90), emergent surgery (AOR, 1.82), obesity (AOR, 1.63), and ulcerative colitis (AOR, 1.60) significantly impacted the risk of conversion. Compared with patients who were successfully completed laparoscopically, converted patients had a significantly higher complication rate (laparoscopic: 23 %; vs. converted: 35.2 % vs. open: 35.3 %), a higher in-hospital mortality rate (laparoscopic: 0.5 %; vs. converted: 0.6 %; vs. open: 1.7 %) and a longer mean hospital stay (laparoscopic: 5.4 days; vs. converted: 8.1 days; vs. open: 8.4 days); however, converted patients had better outcomes compared with the open group. CONCLUSIONS The conversion rate in colorectal surgery was 16.6 %. Converted patients had significantly higher rates of morbidity and mortality compared to successfully completed laparoscopic cases, although lower than open cases. Crohn's disease, prior abdominal surgery, and proctectomy are the strongest predictors for conversion of laparoscopic to open in colorectal operations.

Abstract
BACKGROUND Laparoscopic resection has been considered a relative contraindication for T4 colonic and rectal lesions due to concern over inadequate margins. The objective of this study was to compare planned laparoscopic and open resections of T4 lesions with respect to the positive margin rate. METHODS Data were obtained from the American College of Surgeons National Surgical Quality Improvement Program participant use file to perform a retrospective cohort analysis. The study population consisted of patients that underwent a colorectal resection for a primary T4 lesion during 2011 and 2012. A multiple logistic regression analysis was conducted to determine the adjusted odds ratio (OR) of positive margins based on surgical approach. An inverse probability of treatment weighting (IPTW) analysis was used to account for confounding by indication. A sensitivity analysis including only "as-treated" cases was also performed. RESULTS The sub-selected population consisted of 455 and 406 patients in the laparoscopic and open group, respectively. In the original cohort, demographic variables were similar. The open group had a higher incidence of comorbidities, metastatic disease, and emergency cases. Laparoscopic surgery was found to be no different than open surgery with respect to positive margin status (OR 1.10, p = 0.54). After IPTW adjustment, surgical approach remained a nonsignificant predictor of positive margins (OR 1.18, p = 0.31). The "as-treated" analysis also showed that surgical approach had no significant effect on the positive margin rate (OR 1.24, p = 0.24). CONCLUSIONS Using this large national surgical database, select patients with T4 lesions who underwent planned laparoscopic colorectal resections did not have a significantly higher positive margin rate compared with patients with open operations. Further research is needed to identify the role of laparoscopy in managing T4b lesions before any consensus can be reached regarding its application in locally advanced colon cancer.

Abstract
Colovesical fistulas secondary to diverticular disease may be considered a contraindication to the laparoscopic approach. The feasibility of laparoscopic management of complicated diverticulitis and mixed diverticular fistulas has been demonstrated. However, few studies on the laparoscopic management of diverticular colovesical fistulas exist. A retrospective analysis was performed of 15 patients with diverticular colovesical fistula, who underwent laparoscopic-assisted anterior resection and bladder repair. Median operating time was 135 minutes and median blood loss, 75 mL. Five patients were converted to an open procedure (33.3%) with an associated increase in hospital stay (P = 0.035). Median time to return of bowel function was 2 days and median length of stay, 6 days. Overall morbidity was 20% with no major complications. There was no mortality. There was no recurrence during median follow-up of 12.4 months. These results suggest that laparoscopic management of diverticular colovesical fistulas is both feasible and safe in the setting of appropriate surgical expertise.

Abstract
BACKGROUND Robotic Single-Site™ surgery overcomes the technical constraints of single-access laparoscopy. After performing over 130 Single-Site robotic cholecystectomies and stabilizing operative times, we applied this technology to right colon surgery. METHODS We successfully completed three Single-Site robotic right colectomies (SSRRCs) using the da Vinci Si Surgical System(®) with a Single-Site kit (© Intuitive Surgical™) inserted through a suprapubic incision. RESULTS Overall SSRRC operative time was 218.3 ± 75.9 min. A side-to-side anisoperistaltic anastomosis was fashioned intracorporeally (two cases) or extracorporeally (one case). All patients were discharged within 5 days. There were no complications and oncological principles were satisfied. There were no recurrences up to 12 months. CONCLUSIONS This is the first report of SSRRC with intracorporeal anastomosis using the da Vinci(®) Single-Site™ port inserted through a suprapubic incision. This approach is feasible and safe, with oncological outcomes potentially equivalent to those of robotic or laparoscopic multiport surgery.

Abstract
BACKGROUND Prospective randomized studies and meta-analyses have shown that laparoscopic resection for colonic cancer is equivalent to open resection with respect to the oncological results and has short-term advantages in the early postoperative outcome. The aim of this study was to investigate whether laparoscopic colonic resection has become established as the standard in routine treatment. METHODS Data from the multicenter observational study "Quality assurance colonic cancer (primary tumor)" from the time period from 1 January 2009 to 21 December 2011 were evaluated with respect to the total proportion of laparoscopic colonic cancer resections and tumor localization and specifically for laparoscopic sigmoid colon cancer resections. A comparison between low and high volume clinics (< 30 versus ≥ 30 colonic cancer resections/year) was carried out. RESULTS Laparoscopic colonic cancer resections were carried out in 12 % versus 21.4 % of low and high volume clinics, respectively (p < 0.001) with a significant increase for low volume clinics (from 8.0 % to 15.6 %, p < 0.001) and a constant proportion in high volume clinics (from 21.7 % to 21.1 %, p = 0.905). For sigmoid colon cancer laparoscopic resection was carried out in 49.7 % versus 47.6 % (p = 0.584). Differences were found between low volume and high volume clinics in the conversion rates (17.3 % versus 6.6 %, p < 0.001), the length of the resected portion (Ø 23.6 cm versus 36.0 cm, p < 0.001) and the lymph node yield (Ø n = 15.7 versus 18.2, p = 0.008). There were no differences between the two groups of clinics regarding postoperative morbidity and mortality. The postoperative morbidity and length of stay were significantly lower for laparoscopic sigmoid resection than for conventional sigmoid resection. CONCLUSION The laparoscopic access route for colonic cancer resection is not the standard approach in the participating clinics. The laparoscopic access route has the highest proportion for sigmoid colon resection. The differences in the conversion rates, length of the resected portion and the number of lymph nodes investigated between the low volume and high volume clinics must be viewed critically and must be interpreted in connection with the long-term oncological results.

Abstract
Background The impact of obesity on surgical outcomes after laparoscopic colorectal cancer resection in Chinese patients is still unclear. Methods We retrospectively reviewed the prospectively collected data from 527 consecutive colorectal cancer patients who under went laparoscopic resection from January 2008 to September 2013. Patients were categorized into three groups: nonobese (body mass index (BMI) <25.0 kg/m2), obese I (BMI 25.0 = to 29.9 kg/m2) and obese II (BMI ≥30.0 kg/m2). Clinical characteristics, surgical outcomes and postoperative complications were compared between nonobese, obese I and obese II patients. Results From among the 527 patients, there were 371 patients with in the nonobese group, 142 patients in the obese I group and 14 patients in the obese II group. The patients were well-matched for age, sex and American Society of Anesthesiologists class, except for BMI (P = 0.001). The median operative time correlated highly significantly with increasing weight (median: nonobese = 135 minutes, obese I = 145 minutes, obese II = 162.5 minutes; P = 0.001). There appeared to be a slight tendency toward grade III complications (rated according to the Clavien-Dindo Classification of Surgical Complications) in the obese II group, but this difference was not significant (nonobese = 5.1%, obese I = 3.5% and obese II = 14.3%; P = 0.178). None of the grade III complications which occurred in the obese II group were wound dehiscences that required a stitch. Other aspects, such as estimated blood loss, harvested lymph nodes, operation type, pathological results, conversion rate and overall postoperative complications, were not statistically significant. Conclusion With sufficient experience, laparoscopic colorectal cancer surgery is feasible and safe in obese Chinese patients.

Abstract
BACKGROUND Preoperative radiochemotherapy (RCT) is a standard of care for patients with locally advanced rectal cancer (LARC; stages II and III). Results of our phase II study (BevXelOx-RT) have shown that this regimen is feasible but without a significant improvement of pathological complete response. Whether preoperatively administered bevacizumab, due to its specific toxicity profile, leads to increased rates of surgical complications is currently a subject for debate. This analysis focusses on the surgery-associated spectrum of complications. METHODS Data from 62 patients with rectal cancer (uT3-4; N0/1, M0) of the phase II trial were analyzed. Patients received radiotherapy (50.4/1.8 Gy fractions), simultaneous bevacizumab 5 mg/kg (d1, d15, d29), and capecitabine 825 mg/m(2) twice daily (d1-14, d22-35), oxaliplatin 50 mg/m(2) (d1, d8, d22, d29). Four to six weeks after RCT, surgical resection was performed. RESULTS Overall, 69/69 patients underwent surgery, and 66 (95.7 %) patients had R0 resection. Surgery was mainly conducted (in 66 %) by highly experienced surgeons (>20 resections of rectal cancer/year) with differences between the institutions due to the operative procedures but without effects on the rate of R0 resection or complications. The average duration of surgery was 239 min (±10). Frequency of multivisceral resections (11 %), intraoperative (8 %) and postoperative (43 %) complications were all in the expected range. In particular, we did not observe an increased rate of postoperative bleedings (3 %). The postoperative mortality rate was 0 %. CONCLUSIONS Quantity and the kind of surgery-associated spectrum of complications followed by a preoperative bevacizumab-containing RCT regimen in patients with LARC were in line with comparable trials of bevacizumab-based approaches.

Abstract
BACKGROUND Laparoscopic surgery is increasingly used in the treatment of colorectal cancer and more recently robotic assistance has been advocated. However, the learning curve to achieve surgical proficiency in laparoscopic surgery is ill-defined and subject to many influences. The aim of this review was to comprehensively appraise the literature on the learning curve for laparoscopic and robotic colorectal cancer surgery, and to quantify attainment of surgical proficiency and its implications in surgical clinical trial design. METHODS A systematic review using a defined search strategy was performed. Included studies had to state an explicit numerical value of the learning curve evaluated by a single parameter or multiple parameters. RESULTS Thirty-four studies were included, 28 laparoscopic and 6 robot assisted. Of the laparoscopic studies, nine defined the learning curve on the basis of a single parameter. Nine studies used more than one parameter to define learning, and 11 used a cumulative sum (CUSUM) analysis. One study used both a multiparameter and CUSUM analysis. The definition of proficiency was subjective, and the number of operations to achieve it ranged from 5 to 310 cases for laparoscopic and 15-30 cases for robotic surgery. CONCLUSIONS The learning curve in laparoscopic colorectal surgery is multifaceted and often ill-defined, with poor descriptions of mentorship/supervision. Further, the quantification to attain proficiency is variable. The use of a single parameter to quantify this is simplistic. Multidimensional assessment is recommended; as part of this, the CUSUM model, which assesses trends in multiple surgical outcomes, is useful and appropriate when assessing the learning curve in a clinical setting.

Abstract
BACKGROUND The aim of this study was to evaluate a structured training programme for laparoscopic colorectal surgery in a university colorectal unit over a 6-year period. METHODS Data on patients who underwent laparoscopic colectomy between November 2004 and October 2010 were analyzed. Operations were performed either by the consultant colorectal surgeons or colorectal fellows. The effectiveness and safety of our structured training programme were evaluated. RESULTS During the study period, 813 patients (478 men) with a median age 69 years (range 22-93) underwent laparoscopic colectomy. A total of 370 cases (45.5 %) were performed by four colorectal fellows. Overall, 674 patients (82.9 %) were classified as ASA I or II. The conversion rate was 3.7 %. The conversion rate, intra-operative blood loss, number of lymph nodes retrieved and post-operative recovery were similar between the two groups. When comparing with consultant group, the patients operated by fellows were: (1) significantly older; (2) more were operated on as emergency cases; (3) had pathologically less advanced tumours; (4) less patients with low rectal cancers. There were two surgical mortalities in this series. The morbidities between the two groups were similar. At the end of 3 years of training, the fellows had performed more than 85 cases of laparoscopic colectomies. The level of supervision decreased with increased experience. Finally, experienced fellows were able to supervise more junior colleagues on laparoscopic colectomies. CONCLUSIONS Our results confirmed a structured training programme for laparoscopic colectomy is safe and effective. Reasonable results were achieved even though a high volume of cases were performed by surgical fellows.

Abstract
BACKGROUND This study aimed to identify factors affecting laparoscopic colorectal operative duration and determine the impact of prolonged operative time. METHODS Data were collected prospectively on all laparoscopic colorectal operations performed within 1 institution over a period of 4 years. Patients' demographics, CR-POSSUM scores, intraoperative details, surgeon experience, and postoperative outcomes were recorded and assessed in relation to operative duration. RESULTS Two hundred laparoscopic colorectal operations were performed (137 cancers, 63 benign). Operation duration correlated to operation type (P<0.001) and CR-POSSUM mortality risk (P = 0.03). Operative duration positively correlated with incidence of postoperative complications (P = 0.02) and length of stay (P = 0.05). Operation time >180 minutes was associated with increased incidence of postoperative complications (P = 0.006). CONCLUSIONS The type of laparoscopic colorectal surgical operation performed has a significantly greater impact upon operative duration than individual patient parameters, pathology, or surgical experience. Operative time is associated with a greater risk of complications and longer hospital stay.

Abstract
BACKGROUND Robotic rectal surgery is gaining in popularity. We aimed to define the learning curve of an experienced laparoscopic colorectal surgeon in performing robot-assisted rectal surgery. We hypothesized that there are multiple phases in this learning process. METHODS We performed a retrospective analysis. Consecutive patients who underwent robot-assisted rectal surgery between July 2007 and August 2011 were identified. Operating times were analyzed using the CUSUM (cumulative sum) technique. CUSUMs were model fitted as a fourth-order polynomial. χ(2), Fisher's exact, two independent samples t test, one-way ANOVA, Kruskal-Wallis, and Mann-Whitney tests were used. A p value of <0.05 was considered statistically significant. RESULTS We identified 197 patients. The median (range) total operative, robot, console, and docking times (min) were 265 (145-515), 140 (59-367), 135 (50-360), and 5 (3-40), respectively. CUSUM analysis of docking time showed a learning curve of 35 cases. CUSUM analysis of total operative, robot, and console times demonstrated three phases. The first phase (35 patients) represented the initial learning curve. The second phase (93 patients) involved more challenging cases with increased operative time. The third phase (69 patients) represented the concluding phase in the learning curve. There was increased complexity of cases in the latter two phases. Of phase 1 patients, 45.7% had tumors ≤7 cm from the anal verge compared to 64.2% in phases 2 and 3 (p = 0.042). Of phase 1 patients, 2.9% had neoadjuvant chemoradiotherapy compared to 32.7% of patients in phases 2 and 3 (p < 0.001). Splenic flexure was mobilized in 8.6% of phase 1 patients compared to 56.8% of patients in phases 2 and 3 (p < 0.001). Median blood loss was <50 ml in all three phases. The patients in phases 2 and 3 had a longer hospital stay compared to those in phase 1 (9 vs. 8 days, p = 0.002). There were no conversions. CONCLUSION At least three phases in the learning curve for robot-assisted rectal surgery are defined in our study.

Abstract
BACKGROUND The learning curve for laparoscopic colorectal surgery has not been conclusively analyzed. No reliable framework for case selection during training is available. OBJECTIVE The aim of this study was to analyze the length of the learning curve of laparoscopic colorectal surgeons and to recommend a case selection framework at the early stage of independent practice. DATA SOURCES Medline (1988-2010, October week 4) and Embase (1988-2010) were used for the literature review, databases were retrieved from the authors, and expert opinion was surveyed. STUDY SELECTION Studies describing the learning curve of laparoscopic or laparoscopically assisted colorectal surgery were selected. INTERVENTION No interventions were performed. MAIN OUTCOME MEASURES Learning curves were analyzed by using risk-adjusted, bootstrapped cumulative sum curves. Conversions and complications were independent variables in a multilevel random-effects regression model. Recommendations are based on analysis of ORs and a structured expert opinion gauging process. RESULTS Twenty-three studies were identified, showing great disparity on the length of the learning curve. Seven studies, representing 4852 cases (19 surgeons), were analyzed. Risk-adjusted cumulative sum charts demonstrated the length of the learning curves to be 152 cases for conversions, 143 for complications, 96 for operating time, 87 for blood loss, and 103 for length of stay. Body mass index and pelvic dissection (rectum), especially in male patients, independently increased the risk of complication and conversion. The expert survey revealed that increasing T stage and complicated inflammatory disease are likely to increase the complexity of the case. Based on this evidence, a framework for case selection in training was proposed. LIMITATIONS The generalizability of the study results maybe reduced because of inconsistent data quality and individual variations in the length of the learning curve CONCLUSIONS This multicenter database suggests a length of the learning curve of 88 to 152 cases. The use of the suggested framework may prevent high conversion and complication rates during the learning curve.

Abstract
BACKGROUND Patients with significant comorbidities often are denied laparoscopic colorectal resections, because they are thought to be too "high-risk." This study was designed to examine the feasibility and safety of laparoscopic colorectal resections in high-risk colorectal cancer patients and to compare them with a similar cohort of patients undergoing open resections in the same time period. METHODS This was a single-center, prospective, cohort study conducted at a high-volume, nonuniversity, tertiary care hospital. From a database of 616 patients submitted to elective colorectal surgery for cancer within a fast-track protocol (January 2005 to November 2011), 188 patients who met at least one minor (age >80 years and body mass index (BMI) >30 m/kg(2)) and one major (cardiac, pulmonary, renal or liver disease, diabetes mellitus) criterion were classified as high-risk. Differences in baseline characteristics, intraoperative outcomes, and short-term (30-day) postoperative outcomes, as well as the pathology findings and the readmission and reoperation rates, were compared between the open and laparoscopic cohorts in both high- and low-risk groups and between high- and low-risk groups. RESULTS During the study period, 68 high-risk patients underwent laparoscopic resections and 120 had open surgeries. A shorter length of postoperative stay (6 vs. 9 days, p < 0.0001) and fewer postoperative nonsurgical complications (4 % vs. 19 %, p = 0.003) were observed among the laparoscopic group. Postoperative major (p = 0.774) and minor complications (p = 0.3) and reoperations (p = 0.196) were similar between the two groups, and a significantly lower rate of mortality (1.5 vs. 7.5 %, p = 0.038) was observed in the laparoscopic group than in the open group. CONCLUSIONS Laparoscopic colorectal resection can be safely performed on "high-risk" surgical patients with better results than a similar group of high-risk patients undergoing open colon resections.

Abstract
AIM To study the short-term outcome of patients treated with laparoscopic right colectomy and how intracorporeal anastomosis has improved the outcome. METHODS We retrospectively examined all patients affected by colorectal cancer who underwent a laparoscopic right colectomy between January 2006 and December 2010 in our department. Our evaluation criteria were: diagnosis of colorectal carcinoma at presurgical biopsy, elective surgery, and the same surgeon. We excluded: emergency surgery, conversions from laparotomic colectomy, and other surgeons. The endpoints we examined were: surgical time, number of lymph nodes removed, length of stay (removal of nasogastric tube, bowel movements, gas evacuation, solid and liquid feeding, hospitalization), and major complications. Seventy-two patients were divided into two groups: intracorporeal anastomosis (39 patients) and extracorporeal anastomosis (33 patients). RESULTS Significant differences were observed between intracorporeal vs extracorporeal anastomosis, respectively, for surgical times (186.8 min vs 184.1 min, P < 0.001), time to resumption of gas evacuation (3 d vs 3.5 d, P < 0.001), days until resumption of bowel movements (3.8 d vs 4.9 d, P < 0.001), days until resumption of liquid diet (3.5 d vs 4.5 d, P < 0.001), days until resuming a solid diet (4.6 d vs 5.7 d, P < 0.001), and total hospitalization duration (7.4 d vs 8.5 d, P < 0.001). In the intracorporeal group, on average, 19 positive lymph nodes were removed; in the extracorporeal group, on average, 14 were removed P < 0.001). Thus, intracorporeal anastomosis for right laparoscopic colectomy improved patient outcome by providing faster recovery of nutrition, faster recovery of intestinal function, and shorter hospitalization than extracorporeal anastomosis. CONCLUSION Short-term outcomes favor intracorporeal anastomosis, confirming that a less traumatic surgical approach improves patient outcome.

Abstract
OBJECTIVE This study evaluated the impact of obesity on learning to perform laparoscopic surgery for colon cancer. SUBJECTS AND METHODS We compared the outcomes for 72 patients with colon cancer treated by a single surgeon between June 2005 and July 2008. The first 36 patients who underwent surgery were considered to be during the "early period," and the other 36 patients who underwent surgery as the "late period," and the patients with a body mass index (BMI) ≥25 kg/m(2) were defined as being obese. RESULTS During the early period, the tumor stages of obese patients were less advanced than those of nonobese patients, whereas the length of the operation, surgical blood loss, and wound diameter of obese patients were worse than those of nonobese patients. Furthermore, the tumor stages in the obese patients during the late period were more advanced than those in obese patients during the early period, whereas the length of the operation and number of dissected lymph nodes in the obese patients during the late period were better than those in obese patients during the early period. CONCLUSIONS We demonstrated that the differences of the surgical outcomes between obese and nonobese patients undergoing laparoscopic colon resection decreased as the surgeon's experience increased.

Abstract
BACKGROUND This study aimed to evaluate the learning curve for laparoscopic colorectal resection of a university colorectal unit, the operative outcome in its developing and established period of laparoscopic colorectal resection is compared. METHODS We analyzed 1,031 consecutive patients who underwent laparoscopic colorectal resections for colorectal carcinoma performed in a colorectal unit between April 1992 and December 2008. Multi-dimensional analyses of the learning curves of the institution and seven individual surgeons were performed. RESULTS The operative outcomes of period 2 (2002-2008) was generally better than period 1 (1992-2001), in terms of operative time, number of lymph nodes retrieved, intra-operative blood loss and transfusion. The conversion rate of period 1 was higher than period 2 (19.7% vs. 5.1%, p < 0.001). There were no difference in the rates of intra-operative complications (2% vs. 3.3%, p = 0.32) and major post-operative complications (6% vs. 4.5%, p = 0.28). Analysis of the operative time using moving average method showed that the operative time of period 2 was generally shorter than that of period 1. The operative time transiently increased when there were new trainee surgeons joining the program. The CUSUM analysis of institutional conversion rate showed a steady state being reached at 310 cases. For the rates of intra-operative and major post-operative complications, steady states were both achieved at around 50 cases, and these rates were maintained during the whole study period. CONCLUSIONS Operative outcome of laparoscopic colorectal resection improved with experience. Continuous training of new trainee would not affect the operative outcomes of an established specialized unit.

Abstract
BACKGROUND Evidence demonstrates short-term benefits of laparoscopic surgery for colon cancer. The situation for rectal cancer is less clear. OBJECTIVES This review assessed the use and short-term outcomes of elective open and laparoscopic colon and rectal cancer resections within an area health service. DESIGN This was a multicenter, retrospective review of a prospective database. SETTINGS All elective colon and rectal cancer resections in the western zone of Sydney South West Area Health Service from 2001 until 2008 were included. PATIENTS Included were 1721 patients who underwent either a laparoscopic colon (n = 434) or rectal (n = 157) resection or an open colon (n = 742) or rectal (n = 388) resection. MAIN OUTCOME MEASURES : Outcome measures included operating time, blood loss, adequacy of resection, conversion rate, intensive care unit admission, length of stay, and 26 acute postoperative complications. RESULTS Patients were matched for age, sex, ASA, BMI, and tumor stage. Laparoscopic surgery increased in frequency. Fewer patients experienced a complication in both the laparoscopic colon (28.8 vs 54.4%; p < 0.0001) and rectal (41.4 vs 60.3%; p < 0.0001) group irrespective of age. Laparoscopic operating time for colon and rectal cancer was 24.1 minutes (p < 0.0001) and 25.8 minutes (p < 0.0001) longer, with a low conversion-to-open rate (6.5% and 8.3%; p = 0.44). Laparoscopic surgery resulted in fewer transfusions (0.4 vs 0.7 units; p = 0.0028) and length of stay (7 vs 10 days; p = 0.0011) for colon cancers, and reduced intraoperative hemoglobin drop (20.5 vs 24.8; p = 0.029) and intensive care unit admissions (26.8 vs 36.3%; p = 0.032) for rectal cancers. LIMITATIONS : This was a nonrandomized study with rectal cancers more often resected with the open technique (71.2 vs 28.8%; p < 0.001). CONCLUSIONS Within an area health service, elective laparoscopic resection for colon and rectal cancer had improved short-term outcomes in comparison with open surgery.

Abstract
INTRODUCTION Laparoscopic colorectal surgery has gained widespread acceptance. While many studies have compared laparoscopic and open left-sided resections, there is limited literature on right colonic resections. We aimed to analyse the short-term outcome of laparoscopic (LRH) and open right hemicolectomy (ORH) in our unit. METHODS Consecutive patients undergoing elective right hemicolectomies over a period of 28 months were included in the study. No selection criteria were used to allocate the surgical approach. Study parameters included surgical technique, demographic details, ASA grade, body mass index (BMI), length of hospital stay (LOS), post-operative mortality and morbidity, readmission rate and histopathological data. RESULTS A total of 164 patients underwent right hemicolectomies during the study period (LRH: 89, ORH: 75). Both groups were comparable in age, sex, BMI, ASA grade, tumour stage and lymph node harvest. Four patients (4.5%) in the laparoscopic group required conversion to open surgery. In resections with curative intent, microscopic margins were positive in two patients (3%) in the ORH group compared with one (1%) in the LRH group. Seven ORH patients had an adverse post-operative outcome (three anastomotic leaks, four deaths); there were no deaths/immediate complications in the LRH group (p<0.05). The median LOS for LRH patients (4 days, range: 2-21 days) was significantly shorter than for ORH patients (8 days, range: 3-38 days) (p<0.0001, Mann-Whitney U test). By day 5, 77% of LRH patients were discharged compared with only 21% of patients in the ORH group. There were two readmissions (2.7%) in the ORH group and nine (10.1%) in the LRH group. CONCLUSIONS Our findings demonstrate advantages in favour of LRH in terms of a shorter hospital stay and reduced post-operative major complications. LRH is safe and should therefore be available to all patients requiring colonic resection.

Abstract
BACKGROUND Despite data suggesting improved outcomes with laparoscopic colectomy (LC), less than 10% of colectomies in the Unites States are currently performed laparoscopically. One mechanism for incorporating LC into practice is to attend an LC course (LCC). Postcourse mentorship is recommended by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) and the American Society of Colon and Rectal Surgeons (ASCRS), in addition to course participation, to encourage adoption of the new techniques. Recommendations also include access to at least 25 colectomies annually. Because the use of LC likely will increase, access to mentorship is an important consideration for LCC participants. This study aimed to evaluate mentorship access and related factors for participants in an ongoing LCC. METHODS Participants in seven consecutive single-center LCCs were anonymously surveyed regarding age, specialty, surgical experience, practice, and mentorship availability. Factors associated with mentorship were identified via chi-square and univariate logistic regression. RESULTS Of the 90 participants surveyed, 81 (90%) were men, 51 (56.7%) were general surgeons, 43 (48.9%) were older than 40 years, and 49 (54.4%) had access to a mentor. A majority of the participants (86.7%) performed five or fewer open colorectal cases per month, and 81 (90%) performed five or fewer noncolorectal advanced laparoscopic cases monthly. Factors associated with lack of mentor access included age older than 40 years (P = 0.004), practice as a general surgeon (P = 0.014), and status as a senior attending surgeon (P = 0.029). CONCLUSIONS A significant number of surgeons (45.6%) participating in LCC have limited or no access to mentors. In particular, older surgeons, senior attending surgeons, and general surgeons have the least access to mentors. To encourage adoption of LC, training methods should be adopted that accommodate general surgeons, surgeons with a limited advanced laparoscopic case load, and surgeons without access to mentors. Possible strategies include longer or multisession courses, simulator training, and remote mentoring.

Abstract
AIM Laparoscopic surgery for locally advanced tumours with extramural involvement is still controversial. It is believed that laparoscopic excision of T4 cancers is technically difficult and may result in prolonged operative time, increased conversion rate, added postoperative morbidity, and suboptimal oncological clearance. METHOD Our unit has been practising laparoscopic colorectal surgery since 1992, and all data are entered into a database prospectively. Since 1999 we have routinely used the laparoscopic approach for colorectal cancer resections. Data regarding patients with a histologically T4 cancer operated on between 1999 and 2008 were analysed. Outcomes included operating time, conversion rate, postoperative complications and oncological outcome. RESULTS Over a 10-year period, 146 patients (male 75) with a T4 cancer underwent laparoscopic resection. The median operating time was 125 (range, 46-285) min and the median blood loss was 50 (0-1800) ml. The conversion rate was 16%. Six (4.1%) patients experienced anastomotic leakage. The median number of lymph nodes harvested was 13 (2-40). One hundred and two (70%) patients underwent curative resection. The recurrence rates were 41% and 53% for stage II and III patients, respectively. Four (3.9%) patients had local recurrence. At a median follow up of 18 (1-118) months, the overall survival was 25 months, with median overall survival for patients with stage II, III and IV disease being 63, 36 and 12 months, respectively. CONCLUSION Laparoscopic colectomy in histologically T4 cancer is safe. Oncological outcomes remain satisfactory. Based on our data, provided expertise is available, patients with locally advanced tumours should not be excluded from a laparoscopic approach.

Abstract
BACKGROUND Laparoscopic low anterior resection for rectal cancer is considered to be more technically demanding than laparoscopic colectomy. This study aimed to analyze the learning curve for laparoscopic low anterior resection and to identify the factors that influence this learning curve. METHODS Data from 250 consecutive patients undergoing laparoscopic low anterior resection for rectal cancer, excluding patients with a combined resection such as cholecystectomy, hepatectomy, hysterectomy, or gastrectomy, between December 1996 and April 2010 were analyzed. For operative time, the learning curve was analyzed using the moving average method. The conversion rate and the postoperative complication rate were evaluated in five groups of up to 50 patients each based on the number of cases required for analysis of operative time. In addition, risk factors that influenced conversion to open surgery and postoperative complications were analyzed. RESULTS The learning curve analysis for operative time using the moving average method showed stabilization at 50 cases. The conversion rate decreased significantly by group 4 (151-200 cases). The postoperative complication rate decreased significantly by group 5 (201-250 cases). The significant factors for conversion to open surgery were male sex (odds ratio [OR], 2.6094; 95% confidence interval [CI], 1.1-6.4) and T stage (OR, 2.4793; 95% CI, 1.1-5.8). For postoperative complications, male sex (OR, 3.8590; 95% CI, 1.9-3.8) was significant. In addition, the risk factors for anastomotic leakage were male sex (OR, 15.7659, 95% CI, 3.2-284.8) and multiple firing (2 or more cartridges for rectal transection) (OR, 3.0589; 95% CI, 1.1-9.5). CONCLUSIONS The risk factors affecting the learning curve for laparoscopic low anterior resection were T stage and male sex. In laparoscopic low anterior resection, rectal transection in particular can be technically difficult, and standardization for accurate performance of the same technique for expanded indications is very important.

Abstract
Previous papers studying the effect of surgeon experience on patient outcomes after colorectal surgery are hampered by study design, variable measurements of outcome, and have shown conflicting results. The National Surgical Quality Improvement Program is a validated, risk-adjusted, outcomes-based program used to measure the quality of surgical care. Here, we sought to determine the association between colorectal surgeon experience and short-term patient outcomes using a colorectal surgery-specific National Surgical Quality Improvement Program methodology. We prospectively followed 300 patients operated on by eight colorectal surgeons. The median age was 46 years, male:female ratio was 163:137, and median body mass index was 23. Surgeons were divided into two groups: those with less (Group A) than or greater (Group B) than 5 years experience. Procedures were categorized into 137 (46%) major and 163 (54%) minor cases. Group A surgeons operated on 95 (32%) patients and Group B surgeons operated on 205 (68%) patients. Postoperatively, 101 (31%) patients had complications (Group A = 29; Group B = 72). Four (1%) patients had reoperations (Group A = 0; Group B = 4) and 24 (8%) were readmitted (Group A = 5; Group B = 19) within 30 days of surgery. This prospective study revealed no significant difference in short-term outcomes between colorectal surgeons with less than versus more than 5 years experience.

Abstract
PURPOSE The purpose of the study was to assess the effects of the surgeon's learning curve on the short-term outcome of laparoscopic resections performed for rectal cancer. METHODS A total of 284 patients who underwent laparoscopic resection for rectal cancer performed by 3 different surgical teams between 2005 and 2008 were included in the study. The operative experience was represented by the team's previous surgical case numbers (frequency). Four skill levels were categorized as follows: Level 1: the first 60 cases, Level 2: 61 to 120 cases, Level 3: 121 to 180 cases, and Level 4:>180 cases. Characteristics of the patients, perioperative variables, and the experience levels of the surgeons were analyzed and compared. To investigate the learning curve, we used the following parameters: duration of operative time, conversion rates, general complications, anastomotic leak rates, and oncologic parameters. RESULTS Operative time gradually decreased with increasing experience. The mean operative times for Level 1, Level 2, and Level 3 were 195.0+/-46.7, 181.7+/-34.2, and 172.3+/-33.0 minutes, respectively, whereas the mean operative time for Level 4 was 151.3+/-27.7 minutes (P<0.05). With increased experience, conversion rates, complication rates, anastomotic leak rates, and hospitalization durations decreased (P<0.05). The resected specimen length was found to be longer with increased surgical experience (P<0.05). There were no significant differences among the groups with regard to tumor size, T stage, harvested lymph node count, lateral margin involvement, and R0 resections. CONCLUSIONS The operative time is inversely proportional to the level of skill. Laparoscopic surgical procedures do not have any negative effects on short-term surgical outcome. With the strict application of surgical principles, the oncologic quality of the specimen is not influenced by the experience period. With increased experience, the surgeon feels more confident and performs more difficult and complex laparoscopic surgical interventions for rectal cancer.
