Conservative treatment of intrarectal mesh migration after ventral laparoscopic rectopexy for rectal prolapse.

OBJECTIVE: Ventral rectopexy is a validated treatment for rectal prolapse with a low morbidity rate but a risk of intrarectal mesh migration. The purpose of this study was to report the results of local transanal mesh excision for intrarectal mesh migration after ventral rectopexy.

METHODS: Between January 2004 and March 2011, 312 patients underwent laparoscopic ventral rectopexy in two hospitals. Six patients were treated for intrarectal mesh migration.

RESULTS: Delay between ventral rectopexy and the onset of symptoms was 53 months (4-124 months). All patients have symptoms. Imaging revealed a pelvic abscess in two cases. Intrarectal mesh migration was confirmed by anorectoscopy or clinical examination. Five patients were only treated by local transanal partial mesh excision, and one required a colostomy. Morbidity and mortality were zero. The median hospitalization time was 5 days (3-8 days). After a median postoperative follow-up period of 9 months (1-40 months), one recurrence was observed 2 months after surgery.

CONCLUSION: Local transanal mesh excision for intrarectal mesh migration after laparoscopic ventral rectopexy is a feasible conservative treatment. This simple treatment produced a cure of the pelvic inflammation and closure of the fistula without compromising a more aggressive secondary treatment which was not necessary in our series.
