Background: Transanal total mesorectal excision (TaTME) has been proposed as an approach in patients with mid and low rectal cancer. The TaTME procedure has been introduced in the Netherlands in a structured training pathway, including proctoring. This study evaluated the local recurrence rate during the implementation phase of TaTME. Methods: Oncological outcomes of the first ten TaTME procedures in each of 12 participating centres were collected as part of an external audit of procedure implementation. Data collected from a cohort of patients treated over a prolonged period in four centres were also collected to analyse learning curve effects. The primary outcome was the presence of locoregional recurrence. Results: The implementation cohort of 120 patients had a median follow up of 21⋅9 months. Short-term outcomes included a positive circumferential resection margin rate of 5⋅0 per cent and anastomotic leakage rate of 17 per cent. The overall local recurrence rate in the implementation cohort was 10⋅0 per cent (12 of 120), with a mean(s.d.) interval to recurrence of 15⋅2(7⋅0) months. Multifocal local recurrence was present in eight of 12 patients. In the prolonged cohort (266 patients), the overall recurrence rate was 5⋅6 per cent (4⋅0 per cent after excluding the first 10 procedures at each centre). Conclusion: TaTME was associated with a multifocal local recurrence rate that may be related to suboptimal execution rather than the technique itself. Prolonged proctoring, optimization of the technique to avoid spillage, and quality control is recommended.
Background: Infectious complications and anastomotic leakage affect approximately 30 per cent of patients after colorectal cancer surgery. The aim of this multicentre randomized trial was to investigate whether selective decontamination of the digestive tract (SDD) reduces these complications of elective colorectal cancer surgery. Methods: The effectiveness of SDD was evaluated in a multicentre, open-label RCT in six centres in the Netherlands. Patients with colorectal cancer scheduled for elective curative surgery with a primary anastomosis were eligible. Oral colistin, tobramycin and amphotericin B were administered to patients in the SDD group to decontaminate the digestive tract. Both treatment and control group received intravenous cefazolin and metronidazole for perioperative prophylaxis. Mechanical bowel preparation was given for left-sided colectomies, sigmoid and anterior resections. Anastomotic leakage was the primary outcome; infectious complications and mortality were secondary outcomes. Results: The outcomes for 228 patients randomized to the SDD group and 227 randomized to the control group were analysed. The trial was stopped after interim analysis demonstrated that superiority was no longer attainable. Effective SDD was confirmed by interspace DNA profiling analysis of rectal swabs. Anastomotic leakage was observed in 14 patients (6⋅1 per cent) in the SDD group and in 22 patients (9⋅7 per cent) in the control group (odds ratio (OR) 0⋅61, 95 per cent c.i. 0⋅30 to 1⋅22). Fewer patients in the SDD group had one or more infectious complications than patients in the control group (14⋅9 versus 26⋅9 per cent respectively; OR 0⋅48, 0⋅30 to 0⋅76). Multivariable analysis indicated that SDD reduced the rate of infectious complications (OR 0⋅47, 0⋅29 to 0⋅76).Conclusion: SDD reduces infectious complications after colorectal cancer resection but did not significantly reduce anastomotic leakage in this trial.

Background Although self‐expandable metal stent (SEMS) placement as bridge to surgery (BTS) in patients with left‐sided obstructing colonic cancer has shown promising short‐term results, it is used infrequently owing to uncertainty about its oncological safety. This population study compared long‐term oncological outcomes between emergency resection and SEMS placement as BTS. Methods Through a national collaborative research project, long‐term outcome data were collected for all patients who underwent resection for left‐sided obstructing colonic cancer between 2009 and 2016 in 75 Dutch hospitals. Patients were identified from the Dutch Colorectal Audit database. SEMS as BTS was compared with emergency resection in the curative setting after 1 : 2 propensity score matching. Results Some 222 patients who had a stent placed were matched to 444 who underwent emergency resection. The overall SEMS‐related perforation rate was 7·7 per cent (17 of 222). Three‐year locoregional recurrence rates after SEMS insertion and emergency resection were 11·4 and 13·6 per cent (P = 0·457), disease‐free survival rates were 58·8 and 52·6 per cent (P = 0·175), and overall survival rates were 74·0 and 68·3 per cent (P = 0·231), respectively. SEMS placement resulted in significantly fewer permanent stomas (23·9 versus 45·3 per cent; P < 0·001), especially in elderly patients (29·0 versus 57·9 per cent; P < 0·001). For patients in the SEMS group with or without perforation, 3‐year locoregional recurrence rates were 18 and 11·0 per cent (P = 0·432), disease‐free survival rates were 49 and 59·6 per cent (P = 0·717), and overall survival rates 61 and 75·1 per cent (P = 0·529), respectively. Conclusion Overall, SEMS as BTS seems an oncologically safe alternative to emergency resection with fewer permanent stomas. Nevertheless, the risk of SEMS‐related perforation, as well as permanent stoma, might influence shared decision‐making for individual patients.
Objective: To assess potentially modifiable perioperative risk factors for anastomotic leakage in adult patients undergoing colorectal surgery. Summary Background Data: Colorectal anastomotic leakage (CAL) is the single most important denominator of postoperative outcome after colorectal surgery. To lower the risk of CAL, the current research focused on the association of potentially modifiable risk factors, both surgical and anesthesiological. Methods: A consecutive series of adult patients undergoing colorectal surgery with primary anastomosis was enrolled from January 2016 to December 2018. Fourteen hospitals in Europe and Australia prospectively collected perioperative data by carrying out the LekCheck, a short checklist carried out in the operating theater as a time-out procedure just prior to the creation of the anastomosis to check perioperative values on 1) general condition 2) local perfusion and oxygenation, 3) contamination, and 4) surgery related factors. Univariate and multivariate logistic regression analysis were performed to identify perioperative potentially modifiable risk factors for CAL. Results: There were 1562 patients included in this study. CAL was reported in 132 (8.5%) patients. Low preoperative hemoglobin (OR 5.40, P < 0.001), contamination of the operative field (OR 2.98, P < 0.001), hyperglycemia (OR 2.80, P = 0.003), duration of surgery of more than 3 hours (OR 1.86, P = 0.010), administration of vasopressors (OR 1.80, P = 0.010), inadequate timing of preoperative antibiotic prophylaxis (OR 1.62, P = 0.047), and application of epidural analgesia (OR, 1.81, P = 0. 014) were all associated with CAL. Conclusions: This study identified 7 perioperative potentially modifiable risk factors for CAL. The results enable the development of a multimodal and multidisciplinary strategy to create an optimal perioperative condition to finally lower CAL rates.
SR for large, complex colorectal polyps is still frequently performed and has remained stable. A small percentage of patients underwent ER attempts before SR, and referral for an additional ER attempt only occurred in a minority of cases. To increase ER attempts, implementation of a regional multidisciplinary referral network should be considered.
