Background Extralevator abdominoperineal excision (ELAPE) probably improves the oncological quality of low rectal cancer surgery, as compared to standard abdominoperineal excision (SAPE), possibly due to lower rates of accidental perioperative bowel perforations and lower rates of circumferential resection margin (CRM) positivity. The procedure may however, increase post-operative morbidity. The aim of this paper was to compare outcomes of SAPE and ELAPE for carcinoma of the lower rectum. Methods This is a retrospective study of patients operated on at a single colorectal unit, in a provincial hospital in Denmark. Consecutive patients undergoing abdominoperineal excision (APE) between 2006 and 2012 were included. During this period, a gradual paradigm shift occurred towards adopting ELAPE, although both procedures were performed without a clear selection strategy. We reviewed medical records, including the pathological and radiological data. Patients were divided into two groups, SAPE and ELAPE. Main endpoints were rates of positive CRM, intraoperative bowel perforations, local recurrence rate, length of hospital stay, operative time, and perineal woundrelated complications. Results One hundred and seven patients were included (median age 68 years, range 42-88 years; men = 72). The SAPE group included 39 patients and the ELAPE group 68 patients. Intraoperative bowel perforation was significantly lower in the ELAPE group (20.5 % SAPE vs 7.4 % EL-APE, p = 0.045). The rate of positive CRM was not significantly different (2.6 % SAPE vs 7.4 % ELAPE, p = 0.413). The local recurrence rate was not statistically significant (17.9 % SAPE vs 13.2 % ELAPE, p = 0.513). In the ELAPE group, operative time and hospital stay were significantly longer than the SAPE group (p = 0.001 and p = 0.021, respectively). Conclusions We found low rates of positive CRM after APE compared with the literature. ELAPE did not reduce these rates, and although the local recurrence rate was lower, this did not reach statistical significance. ELAPE has significantly reduced the rate of intraoperative bowel perforation and can optimize low rectal cancer surgery in selected patients. We found no significant differences between the two procedures regarding wound-related complications. A tailored approach and a larger trial with longer follow-up are needed to evaluate long-term results.

Background This study was designed to investigate shortterm and long-term consequences from perforation to the peritoneal cavity during transanal endoscopic microsurgery (TEM) for rectal cancer, with special emphasis on local recurrence and complications. Methods Data from TEM procedures with peritoneal perforations were collected from six prospective databases. Patient, procedure, and follow-up data were extracted. Participating centers were the United Kingdom TEM database, the German TEM database from Mainz, the National Danish TEM database, and databases from the three major Norwegian TEM centers. A total of 888 TEM procedures were registered, and 22 perforations were identified. Results Median age was 82 years. Tumor stages were 14 pT1, 4 pT2, 3 pT3, and 1 pTx. The mean tumor size was 4.1 cm. Radical resection was achieved in 17 patients. All perforations were handled endoscopically. There were no severe complications and no deaths related to the procedure. The mean time of observation was 37 (median 36; range 3-164) months. Local recurrence occurred in two patients, three patients died from the cancer (distant metastasis), and six died from other causes. Conclusions Breaching the peritoneum during TEM is not associated with major short-term complications or long-term oncological consequences provided that primary endoscopic repair is undertaken.

Objective: To compare complication rates after rectal resection using a conventional surgical technique (1983)(1984)(1985)(1986)(1987)(1988)(1989)(1990)(1991)(1992) and mesorectal excision (1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000), and to nd out whether the rate of complications changed with time after the introduction of mesorectal excision. Design: Prospective, observational study. Setting: University hospital, Norway. Patients: All patients who had rectal resections for cancer in the period 1983-2000. Interventions: In the conventional surgery period 217, and in the mesorectal excision period 176, patients had rectal resections. The mesorectal excision period was split in two, the early and the late mesorectal excision period, 88 rectal resections being performed in each period. Total mesorectal excision was done in 118 patients, and partial mesorectal excision in 58. Main outcome measures: Major surgical complications in both periods; intraoperative bleeding, transfusions during the hospital stay, and cardiovascular complications in the mesorectal excision period. Results: 23/217 (11%) developed major surgical complications in the conventional surgery period, compared with 17/88 (19%) in the early mesorectal excision period ( p = 0.04). This was caused by an increased incidence of anastomotic leaks after low anterior resection, being 11/122 (9%) in the conventional surgery period and 12/52 (23%) in the early mesorectal excision period ( p = 0.01).

The aim of this study is to identify factors associated with the decision to perform an abdominoperineal resection (APR) and to assess if these factors or the surgical procedure itself is associated with circumferential resection margin (CRM) involvement, local recurrence (LR), overall survival (OS) and cancer-specific survival (CSS). The Swedish Rectal Cancer Trial (SRCT), TME trial, CAO/ARO/AIO-94 trial, EORTC 22921 trial and Polish Rectal Cancer Trial (PRCT) were pooled. A propensity score was calculated, which indicated the predicted probability of undergoing an APR given gender, age and distance, and used in the multivariate analyses. An APR procedure was associated with an increased risk of CRM involvement [odd ratio (OR) 2.52, p<0.001], increased LR rate [hazard ratio (HR) 1.53, p=0.001] and decreased CSS rate (HR 1.31, p=0.002), whereas the propensity score was not. The results suggest that the APR procedure itself is a significant predictor for non-radical resections and increased risk of LR and death due to cancer for patients with advanced rectal cancer.
Surgery may be curative for patients with a localized perforation of rectal carcinoma
British Journal of Surgery, 1999
Background Perforation at the time of operation adversely affects the prognosis of rectal cancer. These procedures have been termed ‘palliative’ or ‘non-curative’. The long-term outcome of generalized perforations may be different from that of localized or contained perforations. Although the oncological results may be compromised when the tumour is perforated, results in cases where the perforation is contained may not be as bad as previously thought. An attempt was made to examine the intermediate and long-term results for locally contained perforated rectal cancers. Methods Some 848 patients with rectal cancer were operated on between March 1989 and December 1995. Of these, 42 (5 per cent) had a locally contained perforation of the rectum. Median follow-up was 23 (range 12–74) months. Results The survival of patients with locally contained tumour perforation who underwent resection without macroscopic residual disease (40 per cent at 5 years) was significantly better than that of...
A National Perspective on the Decline of Abdominoperineal Resection for Rectal Cancer
Annals of Surgery, 2008
Objective: To assess rates of abdominoperineal excision of the rectum (APER) for rectal cancer between centers and over time, and to evaluate the influence of patient characteristics, including social deprivation, on APER rate. Methods: Data on patients undergoing APER or anterior resection (AR) in England were extracted from a national administrative database for the years 1996 to 2004. The primary outcome was the proportion of patients presenting with rectal cancer undergoing APER. Hierarchical logistic regression was used to identify independent factors associated with a nonrestorative resection. Results: Data on 52,643 patients were analyzed, 13,109(24.9%) of whom underwent APER. The APER rate significantly reduced over the study period from 29.4% to 21.2% (P Ͻ 0.001). Operative mortality following AR decreased significantly during the period of study (5.1% to 4.2%, P ϭ 0.002), while that following APER did not (P ϭ 0.075). Male patients were more likely to undergo APER (P Ͻ 0.001), whereas those with an emergency presentation more commonly underwent AR (P Ͻ 0.001). Independent predictors of increased APER rate were male gender (odds ratio ͓OR͔ ϭ 1.239, P Ͻ 0.001) and social deprivation (most vs. least deprived; OR ϭ 1.589, P Ͻ 0.001), whereas increasing patient age (OR ϭ 0.977, P ϭ 0.027 per 10-year increase), year of study (2003/4 vs. 1996/7; OR ϭ 0.646, P Ͻ 0.001) and initial presentation as an emergency (OR ϭ 0.713, P Ͻ 0.001) were associated with lower APER rates. After accounting for case-mix, there was significant between-center variability in APER rates. Conclusion: Socially deprived patients were more likely to undergo abdominoperineal resection. Significant improvements in rates of nonrestorative resection were seen over time but although short-term outcomes following AR have improved, those following APER have not. Permanent stoma rates following rectal cancer surgery may be considered a surrogate marker of surgical quality.
Transanal total mesorectal excision for rectal cancer has been suspended in Norway
British Journal of Surgery, 2019
Background: Transanal total mesorectal excision (TaTME) for rectal cancer has emerged as an alternative to the traditional abdominal approach. However, concerns have been raised about local recurrence. The aim of this study was to evaluate local recurrence after TaTME. Secondary aims included postoperative mortality, anastomotic leak and stoma rates. Methods: Data on all patients who underwent TaTME were recorded and compared with those from national cohorts in the Norwegian Colorectal Cancer Registry (NCCR) and the Norwegian Registry for Gastrointestinal Surgery (NoRGast). Kaplan-Meier estimates were used to compare local recurrence. Results: In Norway, 157 patients underwent TaTME for rectal cancer between October 2014 and October 2018. Three of seven hospitals abandoned TaTME after a total of five procedures. The local recurrence rate was 12 of 157 (7⋅6 per cent); eight local recurrences were multifocal or extensive. The estimated local recurrence rate at 2⋅4 years was 11⋅6 (95 per cent c.i. 6⋅6 to 19⋅9) per cent after TaTME compared with 2⋅4 (1⋅4 to 4⋅3) per cent in the NCCR (P < 0⋅001). The adjusted hazard ratio was 6⋅71 (95 per cent c.i. 2⋅94 to 15⋅32). Anastomotic leaks resulting in reoperation occurred in 8⋅4 per cent of patients in the TaTME cohort compared with 4⋅5 per cent in NoRGast (P = 0⋅047). Fifty-six patients (35⋅7 per cent) had a stoma at latest follow-up; 39 (24⋅8 per cent) were permanent. Conclusion: Anastomotic leak rates after TaTME were higher than national rates; local recurrence rates and growth patterns were unfavourable. * Members of the Norwegian TaTME Collaborative Group are co-authors of this article and can be found under the heading Collaborators.

Background With conventional blunt surgical resection of rectal cancer, local recurrence rates are high and the individual surgeon putatively influences patient outcome. With total mesorectal excision (TME) local recurrence rates have been reduced and intersurgeon variability may be less important. The ‘TME project’ was a collaborative project that included surgical workshops in Stockholm between 1994 and 1997. The aim of this study was to assess the impact of the project on the practice of rectal cancer surgery in Stockholm and to analyse whether surgeon case volume and participation in the workshops influenced patient outcome. Methods All 652 patients who had an abdominal resection for rectal cancer in Stockholm between 1995 and 1997 were included. Outcome was compared in patients operated on by teams that included high-volume surgeons (more than 12 operations per year) with teams that included low-volume surgeons (12 operations or fewer per year), as well as between teams that in...
