Purpose: The aim of this study was to demonstrate the feasibility, effectiveness, and reliability of a new technique for treating overt rectal mucosal prolapse using a stapler device.
Methods: Eighteen consecutive patients with overt rectal mucosal prolapse were selected for the study. Preoperative anal manometry and cinedefecography demonstrated no anal incontinence and the absence of full-thickness rectal prolapse. One or two purse strings were prepared 3 to 4 cm distally to the dentate line and tied on a 33 mm circular stapler introduced through the anus and then fired.
Results: The operation lasted an average of 15 minutes, and no local complications were recorded. Supplementary hemostatic sutures (2 to 6 stitches) were sometimes necessary. Seven patients did not require postoperative analgesia, whereas eight patients received one or two administrations of analgesics. Longer-lasting analgesic treatment (4 days) was necessary in only three patients. Sixteen patients were discharged after 48 hours, and only 1 after four days because of pulmonary infection. Patients resumed normal activities after a median period of three days. Median follow-up was 20 months. The prolapse was eliminated in all cases. No stricture was found at anal exploration, and no episodes of anal incontinence or bleeding were recorded. Postoperative manometry did not show significant changes compared with preoperative findings.
Conclusions: This new surgical technique is safe, effective, and rapid, causing minimum or no postoperative pain and could be proposed to replace traditional surgery for this common condition.
