Résumé
Objective To explore the new approach of operatively treating internal rectal mucosal prolapse. Methods 42 patients with internal rectal mucosal prolapse were treated with circular stapling procedure, and followed-up for 2～24 months after operation. Results Mean operative time circular stapling procedure was 18 minutes, and mean hospitalization time of the patients was 3 days. The clinical symptoms were obviously improved after operation. Anastomotic stoma bleeding was found in 9 patients (21.4 %) during operation. Urinary retension was found in 17 patients (40.5%), who needed catheterization. Sensation of rectal tenesmus occurred in 6 patients(14.3%). Infection, anal incontinence and rectovaginal fistula were not found in all the patients. Conclusion Circular stapling procedure is safe, simple and effective technique for treating internal rectal mucosal prolapse with the advantages of minimal invasion.
