Aim The long‐term risk of definitive stoma after sphincter‐saving resection ( SSR ) for rectal cancer is underestimated and has never been reported for ultralow conservative surgery. We report the 10‐year risk of definitive stoma after SSR for low rectal cancer. Method From 1994 to 2008, patients with low rectal cancer who were suitable for SSR were analysed retrospectively. Patients were divided into the following four groups: low colorectal anastomosis ( LCRA ); coloanal anastomosis ( CAA ); partial intersphincteric resection ( pISR ); and total intersphincteric resection ( tISR ). The end‐point was the risk of a definitive stoma according to the type of anastomosis. Results During the study period, 297 patients had SSR for low rectal cancer. The incidence of definitive stoma increased from 11% at 1 year to 22% at 10 years. The reasons were no closure of the loop ileostomy (4.7%), anastomotic morbidity (6.5%), anal incontinence (8%) and local recurrence (5.2%). The risk of definitive stoma was not influenced by type of surgery: 26% vs 18% vs 18% vs 19% ( P = 0.578) for LCRA , CAA , pISR and tISR , respectively. Independent risk factors for definitive stoma were age > 65 years and surgical morbidity. Conclusion The risk of a definitive stoma after SSR increased two‐fold between 1 and 10 years after surgery, from 11% to 22%. Ultralow conservative surgery ( pISR and tISR ) did not increase the risk of definitive stoma compared with conventional CAA or LCRA.
