Combined side-to-end anastomosis with temporary end colostomy for the management of selected left-sided colonic emergencies.

Management of surgical emergencies of the left colon commonly requires excision of the colonic segment bearing the lesion, creation of an end colostomy, and closure of the rectosigmoid stump. Closure of the end stoma may be technically challenging. During this study, we used a new surgical technique involving the creation of an end-to-side anastomosis of the rectosigmoid stump to the base of the proximal colonic segment in association with an end colostomy. During a 15-year period, 23 patients were offered this type of surgery. Mortality was zero. Complications were observed in seven patients (morbidity, 7/23). Mean hospitalization time was 12.3 days. Closure of the colostomy was performed approximately 1 month after initial surgery and was easily performed using a mechanical stapler, either intraperitoneally or even extraperitoneally. No complications were observed after closure of the colostomy. The described technique is a useful alternative for the management of selected patients with left-sided colonic surgical emergencies. Its main advantage is that it greatly facilitates colostomy closure, which is performed earlier compared with the colostomy closure after a typical Hartmann's procedure.
