Background Anastomotic leakage is a major concern after resection for low rectal cancer. Therefore, the use of a defunctioning stoma (DS) has been suggested, but limited data exist to clearly determine the necessity of a routine diversion. In our department, the indication of DS was evaluated subjectively by the operating surgeon. The aim of this study was to evaluate the selective use of fecal diversion. Materials and methods Retrospective chart review of patients who underwent low anterior resection for carcinoma was performed. The incidence and consequences of clinical leaks were determined in these patients who were considered in two groups: defunctioning stoma and no defunctioning stoma. Results From 1995 to 2005, 132 consecutive patients underwent low anterior resection; a DS was performed in 42 patients (31.8%). Median level of anastomosis was 4 cm in both groups. Overall clinical leakage rate was 9.8%: 7.1% ( n  = 3) with a DS and 11% ( n  = 10) without a stoma. Mortality rate was 1.5% ( n  = 2), both in the unprotected group. No patient in the diversion group required a permanent stoma, contrasting with four unprotected patients in which continuity could not be restored after break down of the anastomosis. Conclusion Finding lower clinical leakage rate in a probable higher risk group and better outcome when a leak occurs in our study constituted strong evidence of the effectiveness of a DS. Selective use of a DS based on subjective assessment at the time of surgery could not allow experienced surgeons to perform single-stage procedure safely. Construction of a DS seems useful for patients with distal rectal cancer.
