Failing to reverse a diverting stoma after lower anterior resection of rectal cancer
2014
Abstract Background A diverting stoma is an accepted adjunct to low anterior resection (LAR) for rectal cancer. However, some patients do not undergo a subsequent procedure to have the stoma reversed. We aim to determine incidence and risk factors for nonclosure of the diverting stoma. Methods This is a retrospective study of stage I to III rectal cancer patients at a single institution having LAR with curative intent and a diverting stoma. Results We studied 162 patients. Prevalence of nonclosure of the temporary stoma was 14.5% within 13 months of the index surgery. On a multivariate linear regression model, nonclosure was associated with anastomotic leak (odds ratio 9.89, 2.31 to 43.93, P P Conclusions Prevalence of nonclosure of a diverting stoma after LAR for rectal cancer is substantial (14.5%). Patients should be counselled regarding this risk with particular attention to potential risk factors.
