- BackgroundPreoperative inflammation might cause and also be a marker for anastomotic leakage after anterior resection for rectal cancer. Available biomarker indices such as the modified Glasgow Prognostic Score (mGPS) or the C-reactive protein-to-albumin ratio (CAR) may be clinically useful for leakage assessment.MethodsPatients who underwent anterior resection for rectal cancer during 2014-2018 from a multicentre retrospective cohort were included. Data from the Swedish Colorectal Cancer registry and chart review at each hospital were collected. In a subset of patients, preoperative laboratory assessments were available, constituting the exposures mGPS and CAR. Anastomotic leakage within 12 months was the outcome. Causally oriented analyses were conducted with adjustment for confounding, as well as predictive models.ResultsA total of 418 patients were eligible for analysis. Most patients had mGPS = 0 (84.7%), while mGPS = 1 (10.8%) and mGPS = 2 (4.5%) were less common. mGPS = 2 (OR: 4.11; 95% CI: 1.69-10.03) seemed to confer anastomotic leakage, while this was not seen for mGPS = 1 (OR 1.09; 95% CI: 0.53-2.25). A cut off point of CAR > 0.36 might be indicative of leakage (OR 2.25; 95% CI: 1.21-4.19). Predictive modelling using mGPS rendered an area-under-the-curve of 0.73 (95% CI: 0.67-0.79) at most.DiscussionPreoperative inflammation seems to be involved in the development of anastomotic leakage after anterior resection for cancer. Inclusion into prediction models did not result in accurate leakage prediction, but high degrees of systemic inflammation might still be important in clinical decision-making.

- BACKGROUND: Anastomotic leakage after anterior resection for rectal cancer is more common after total compared to partial mesorectal excision but might be mitigated by a defunctioning stoma.OBJECTIVE: The aim is to assess how anastomotic leakage is affected by type of mesorectal excision and defunctioning stoma use.DESIGN: This is a retrospective multicenter cohort study evaluating anastomotic leakage after anterior resection. Multivariable Cox regression with hazard ratios and 95% confidence intervals was employed to contrast mesorectal excision types and defunctioning stoma use with respect to anastomotic leakage, with adjustment for confounding.SETTINGS: This multicenter study included patients from 11 Swedish hospitals between 2014 and 2018.PATIENTS: Patients who underwent anterior resection for rectal cancer were included.MAIN OUTCOMES MEASURES: Anastomotic leakage rates within and after 30 days of surgery are described up to one year after surgery.RESULTS: Anastomotic leakage occurred in 24.2% and 9.0% of 1126 patients operated with total and partial mesorectal excision, respectively. Partial compared to total mesorectal excision was associated with a reduction in leakage, with an adjusted HR of 0.46 (95% CI: 0.29-0.74). Early leak rates within 30 days were 14.9% with and 12.5% without a stoma, while late leak rates after 30 days were 7.5% with and 1.9% without a stoma. After adjustment, defunctioning stoma was associated with a lower early leak rate (HR 0.47; 95% CI: 0.28-0.77). However, the late leak rate was non-significantly higher in defunctioned patients (HR 1.69; 95% CI: 0.59-4.85).LIMITATIONS: This study was limited by its retrospective observational study design.CONCLUSIONS: Anastomotic leakage is common up to one year after anterior resection for rectal cancer, where partial mesorectal excision is associated with a lower leak rate. Defunctioning stomas seem to decrease the occurrence of leakage, though partially by only delaying the diagnosis.

- Some colorectal surgeons advocate routine splenic flexure mobilization (SFM) when performing anterior resection for rectal cancer to ensure a tension-free anastomosis. Meta-analyses of smaller studies suggest that this approach does not influence anastomotic leakage rates, but larger multicentre studies are needed to confirm the safety of a selective strategy. The aim of this study is to evaluate the impact of SFM on anastomotic leakage.This is a retrospective multicentre cohort study, comprising 1109 patients operated with anterior resection for rectal cancer in 2014-2018. Exposure was SFM, while anastomotic leakage within a year constituted the outcome. Stratified analyses were performed for type of mesorectal excision and surgical approach, as well as sensitivity analysis considering vascular tie placement. Multivariable Cox regression with hazard ratios (HRs) and 95% confidence intervals (CIs) was employed to adjust for confounding, while multiple imputation was used for missing data.SFM was performed in 381 patients (34.4%). Anastomotic leakage occurred in 83 (21.8%) and 123 (20.3%) patients operated with and without SFM, respectively. SFM was neither clearly detrimental nor beneficial regarding anastomotic leakage (adjusted HR = 0.82; 95% CI: 0.59-1.15), with no apparent differences for total or partial mesorectal excision and minimally invasive or open surgery. Concurrent high vascular ligation did not impact these results, and there was no evidence of interaction from centers with a more common use of SFM.SFM did not seem to influence the risk of anastomotic leakage after anterior resection for rectal cancer, regardless of type of mesorectal excision, use of minimally invasive surgery, or high vascular ligation.
