Permanent stoma rates: a misleading marker of quality in rectal cancer surgery

Abstract

Our unit provides multivisceral surgery for locally advanced rectal cancer and receives a substantial number of tertiary referrals. Many of the rectal cancers referred are locally advanced or threaten the anal sphincter. This study demonstrates that the complexity of a unit's case-mix can have a profound effect on the permanent stoma rate. Stoma rates taken at face value do not therefore provide an accurate representation of surgical quality. What does this paper add to the literature? The study reviews the practice of a colorectal surgical unit with an interest in multivisceral surgery with regard to the permanent stoma rate. The reasons for nonrestorative surgery are analysed, and the problems associated with the use of stoma rates as a marker of quality in colorectal surgery are highlighted.
