Laparoscopic ventral rectopexy using the transanal vacuum test for complete rectal prolapse.

ABSTRACT

Laparoscopic ventral rectopexy was performed in 84 patients with complete rectal prolapse from January 2016 to December 2019. In the initial 27 cases, three cases had recurrence, especially in cases of a long rectal prolapse measuring over 10 cm. In order to avoid recurrence, the transanal vacuum test was performed following the dissection of the rectovaginal septum towards the pelvic floor. The disappearance of rectal prolapse is confirmed by the intraoperative transanal vacuum test. When the posterior wall of the rectum showed the presence of prolapse according to the transanal vacuum test, then laparoscopic ventral rectopexy was converted to laparoscopic posterior rectopexy. In 94 cases in which laparoscopic ventral rectopexy was attempted, laparoscopic ventral rectopexy was completed in 57 cases, while the procedure was converted to laparoscopic posterior rectopexy in 37 cases. The recurrence rate following laparoscopic ventral rectopexy decreased from 11.1% (3/27) to 1.7% (1/57) after beginning to use the transanal vacuum test. Laparoscopic ventral rectopexy using the transanal vacuum test is therefore considered to be a useful technique to reduce postoperative recurrence.
