Sutured posterior abdominal rectopexy with sigmoidectomy compared with Marlex rectopexy for rectal prolapse.

Two treatment policies for rectal prolapse were prospectively assessed between April 1986 and January 1989. Sixteen patients had a Marlex mesh posterior rectopexy alone and 13 underwent a sigmoidectomy combined with a sutured posterior rectopexy. Preoperative and post-operative assessment included manometry, a saline infusion test and video-proctography. Hospital stay, control of prolapse and complications were comparable in both groups. Restoration of continence occurred in nine of the 12 incontinent patients after Marlex rectopexy, compared with six of nine after sutured rectopexy and sigmoidectomy. Constipation persisted in three patients who were constipated before operation and in four of 13 who had previously normal bowel habits became constipated after Marlex rectopexy; constipation persisted in one of five previously constipated patients while none with previously normal bowel habits became constipated after sutured rectopexy and sigmoidectomy. Sigmoidectomy combined with sutured rectopexy was safe and as efficient as Marlex rectopexy in prolapse control and improvement of continence; significantly fewer patients were constipated (one of 13) after sigmoidectomy than following rectopexy alone (seven of 16). A randomized trial now seems justified.
