Protective stoma after deep anterior rectal resection: pro

There is still controversy about the necessity of a diverting stoma after deep anterior resection with total mesorectal excision for rectal cancer. Recent results of randomized controlled trials and from systematic reviews have improved the currently available data. A significant benefit was shown for patients with diverting stoma in terms of clinically relevant anastomotic leakage and re-operation rates. The influence on mortality is not as clear. However, analysis of the data of 19 prospective studies within a systematic review including more than 9,000 patients, revealed a significant benefit for stoma creation. Furthermore, the rate of patients with stoma 5 years after primary resection was lower in the group of patients with diverting stoma. The purpose of this manuscript is to show the necessity of a diverting stoma based on the currently available data.
