Large variation in the use of defunctioning stomas after rectal cancer surgery. A lack of consensus

AbstractBackground and objectives: When deciding about the use of a defunctioning stoma in rectal cancer surgery, benefits and risks need to be weighed. This study investigated: (1a) factors associated with the use of defunctioning stomas; (1b) hospital variation; and (2) surgeons’ perceptions regarding factors that determine this decision.Methods: Population-based data from the Dutch Surgical Colorectal Audit were used. Factors for receiving a defunctioning stoma were analyzed with multivariate logistic regression analysis. Hospital variation was assessed before and after case-mix adjustment. A survey was performed among gastroenterological surgeons on the importance of factors for the decision to construct a defunctioning stoma.Results: In total 4368 patients were analyzed and 103 (34%) surgeons participated. Male gender, higher body mass index, lower tumors, preoperative radiotherapy, and treatment in a teaching/university hospital increased the odds for a defunctioning stoma. Unadjusted hospital varia...
