title: Circular stapling procedure for mucosal prolapse of the rectum associated with outlet obstruction.
abstract: The aim of this study was designed to investigate the outcome from using the new circular stapling device in the surgical treatment for mucosal prolapse of the rectum associated with outlet obstruction. The treatment consisted of resection of the mucosal prolapse through a transverse incision and resecting a suitable part of the mucosa between the rectum and the anal canal, using an HCS33 circular stapler. Eleven patients successfully underwent this operation without morbidity or mortality, and were assessed clinically and by rectoanal manometry and defecography pre- and post-operation. The mean operating time was 39 (range 22-49) min. The postoperative proctalgia and complications were mild, and the patients were discharged at 4 days after the operation. The pre-operative constipation was improved, and the patient's satisfaction was increased at one month after operation in comparison with the preoperative level. Rectoanal function test at 6 months after the operation demonstrated normalization of the maximum resting and squeezing pressures of the anal canal and rectal compliance to the normal levels. No patient has had recurrence of symptoms during the follow-up period. Our data suggest that this procedure may be a useful surgical treatment, as it causes little postoperative complication and enables early discharge of the patients. However, long-term outcomes of recurrence, continence, and constipation need to be evaluated in a more extended follow-up.
