A retrospective 10-year study was conducted on 473 patients who underwent rectal cancer surgery, to evaluate a surgical procedure which has been generally abandoned, but which we believe has a significant potential to reduce the incidence of the severe and often fatal complications caused by anastomotic breakdown following low anterior resection, especially when a covering stoma is absent. This procedure involves separating the anastomosis and sacral drain from the abdominal cavity by suturing the parietal peritoneum to the colon and mesocolon, and placing the sacral drain outside the peritoneal cavity, whereby contamination of the abdominal cavity is avoided should anastomostic leakage occur. Sphincter preservation was possible in 343 patients (72.5%) while 116 (24.5%) underwent abdominoperineal resection (APR). Of 331 patients who underwent sphincter-saving resection (SSR), 31 (9.4%) had primary protective colostomies. Radical RO-resection according to the International Union Against Cancer (UICC) was performed in 405 patients, and 65 (19.6%) underwent extended resections. Anastomotic leakage became clinically manifest in 33 patients (10%; or 11% when those with primary colostomies were excluded). Only 1 patient required relaparotomy while 32 were successfully treated with temporary loop colostomy in the right epigastrium. No deaths occurred following anastomotic leakage breakdown. Overall operative hospital mortality was 3.0%; 2.7% and 2.6% in the SSR and APR groups, respectively. The adjusted 5-year survival rates were 60% for APR and 72% for SSR.
