Description of intervention(s) / exposure
Patients were either operated with the rectal stump left in-situ or extra-fascially. Our study then measured 30 day postoperative outcomes (pelvic and systemic sepsis, wound infection, overall complications) and mortality rates after different rectal stump management techniques in subtotal colectomy for severe colitis.

Statistical methods / analysis
Statistical analyses were performed using GraphPad Prism software version 7 (GraphPad Software Inc., San Diego, CA). Continuous variables were expressed as mean (standard deviation) for parametric data and median (range) for non-parametric. Categorical and binary variables were summarised as a total followed by a percentage. The Fisher-exact test was used for smaller patient numbers (n < 5), and the chi-square test was used for larger patient numbers (n > 5) to analyze categorical variables. The Welch’s t-test was used for continuous parametric data, and the Mann-Witney U test was used for continuous non-parametric data.

Summary
Brief summary
The primary purpose of this study was to evaluate the current practice at a single inflammatory bowel (IBD) tertiary referral center, in order to identify the optimal surgical and medical management of the rectal stump after an subtotal colectomy for severe colitis. We hypothesize that an extra-fascial management of the rectal stump will have lower complication rates compared to an in-situ management of the rectal stump.
