[Does retroperitonealization of anastomoses in left-sided large intestine resections lower postoperative mortality?].

601 low anterior anastomoses of the rectum are analysed concerning suture techniques, leakage rate and operative mortality. None of the patients who developed a dehiscence (9.3%) died due to the extraperitoneal position of the anastomosis and the continuous sump-suction drainage of the retroperitoneum. The operative mortality was 1.5%.
