Background The aim of this nationwide observational study was to evaluate factors associated with multivisceral resection (MVR), margin status and overall survival in locally advanced colorectal cancer (CRC). Material and methods Patients with (y)pT4, cM0 CRC between 2006 and 2017 were selected from the Netherlands Cancer Registry. Cox-proportional hazards modelling was used for survival analysis, stratified for T4a and T4b. Annual hospital volume cut-off was 75 for colon and 40 for rectal resections. Results A total of 11.930 patients were included and 2410 patients (20.2%) underwent MVR. Factors associated with MVR for colon and rectal cancer besides cT4 category were more recent diagnosis (OR 3.61, CI 95% 3.06–4.25 (colon) and OR 2.72, CI 95% 1.82–4.08 (rectum)) and high hospital volume (OR 1.20, CI 95% 1.05–1.38 (colon) and OR 2.17, CI 95% 1.55–3.04 (rectum)). Patients ≥70 year were less likely to undergo MVR for colon cancer (OR 0.80, 95% CI 0.70–0.90). Risk factors for incomplete resection were cT4 (OR 3.08, CI 95% 2.35–4.04 (colon) and OR 1.82, CI 95% 1.13–2.94 (rectum)) and poor/undifferentiated tumors (OR 1.41, CI 95% 1.14–1.72 (colon) and OR 1.69, CI 95% 1.05–2.74 (rectum)). More recent diagnosis was independently associated with less incomplete resections in colon cancer (OR 0.58, CI 95% 0.40–0.76). Independent predictors of survival were age, resection margin, nodal status and adjuvant chemotherapy, but not MVR. Conclusion Treatment of locally advanced CRC with MVR at population level was influenced by year of diagnosis and hospital volume. Margin status in colon cancer improved substantially over time.

Background Bowel dysfunction after rectal cancer surgery is common, with some experiencing low anterior resection syndrome (LARS) is common after rectal cancer surgery. This study examined if transanal total mesorectal excision (TaTME) has a similar risk of LARS and altered quality of life (QoL) as patients who undergo low anterior resection (LAR). Methods Patients who underwent TaTME or traditionally approached total mesorectal excision in a prospective colorectal cancer cohort study (2014–2019) were propensity score matched in a 1 : 1 ratio. LARS and QoL scores were assessed before and after surgery with a primary endpoint of major LARS at 12 months analysed for possible association between factors by logistic regression. Results Of 61 TaTME and 317 LAR patients eligible, 55 from each group were propensity score matched. Higher LARS scores (30.6 versus 25.4, P = 0.010) and more major LARS (65 versus 42 per cent, P = 0.013; OR 2.64, 95 per cent c.i. 1.22 to 5.71) were reported after TaTME. Additionally, QoL score differences (body image, bowel frequency, and embarrassment) were worse in the TaTME group. Conclusions TaTME may be associated with more severe bowel dysfunction than traditional approaches to rectal cancer.

Background Total mesorectal excision (TME) gives excellent oncological results in rectal cancer treatment, but patients may experience functional problems. A novel approach to performing TME is by single‐port transanal minimally invasive surgery. This systematic review evaluated the functional outcomes and quality of life after transanal and laparoscopic TME. Methods A comprehensive search in PubMed, the Cochrane Library, Embase and the trial registers was conducted in May 2019. PRISMA guidelines were used. Data for meta‐analysis were pooled using a random‐effects model. Results A total of 11 660 studies were identified, from which 14 studies and six conference abstracts involving 846 patients (599 transanal TME, 247 laparoscopic TME) were included. A substantial number of patients experienced functional problems consistent with low anterior resection syndrome (LARS). Meta‐analysis found no significant difference in major LARS between the two approaches (risk ratio 1·13, 95 per cent c.i. 0·94 to 1·35; P = 0·18). However, major heterogeneity was present in the studies together with poor reporting of functional baseline assessment. Conclusion No differences in function were observed between transanal and laparoscopic TME., A novel surgical technique for total mesorectal excision (TME) is single‐port transanal minimally invasive surgery. This systematic review aimed to evaluate the functional outcomes and quality of life after transanal total mesorectal excision (TaTME) and compare them with those of laparoscopic TME (LapTME). No differences between TaTME and LapTME were seen in terms of impaired functioning and reduced quality of life after rectal cancer surgery. However, major heterogeneity was present in the studies together with poor reporting of functional baseline assessment. Comparable function

Introduction Functional bowel complaints, referred to as Low Anterior Resection Syndrome (LARS), are common after sphincter-saving surgical procedures and have a severe impact on quality of life (QoL). Care for LARS patients is complex and surgeons underestimate or misinterpret its associated symptoms. This study aimed to explore the impact of LARS from a patient perspective facilitating the construction of a set of recommendations improving current care stratagems. Methods In a non-academic Dutch teaching hospital, three focus group sessions were conducted with 16 patients (males = 50%) who had undergone colorectal surgery between 2012 and 2017. A trained moderator orchestrated patient-discussion regarding illness perception and health-care needs. Transcripts were analysed using inductive content analysis. Results Three themes were identified: illness perception, preoperative care and postoperative supportive care. Specific attention and screening for LARS is deemed necessary for breaking the taboo surrounding it. Extension of preoperative counselling on the normal postoperative course, including ways to optimize social support, were identified as crucial. After discharge, patients experienced a lack of supportive care regarding functional complaints and did not know who to counsel. In addition, they felt intrinsically motivated to actively prepare for surgery, i.e. by participating in prehabilitation programs. Conclusion Exploring perspectives in LARS patients resulted in the identification of potential improvements in current care pathways. Recommendations on ways to improve information provision, screening of LARS and methods to intervene in the gap of supportive care after discharge are presented. We recommend to implement these measures as QoL of patients undergoing colorectal cancer surgery may be improved.
