Improvement of Rectal Prolapse Using an Over-the-scope Clip System.

Rectal prolapse is typically treated surgically, and internal therapy has not been reported. We encountered a case of rectal prolapse that improved with an over-the-scope clip (OTSC) system. An 81-year-old woman complaining of anorectal pain underwent colonoscopy, and rectal prolapse was observed prior to colonoscopy. Unfortunately, rectal perforation occurred while attempting endoscopic reversal. The OTSC system was used to close the rectal perforation and subsequently improved her rectal prolapse, probably because the rectal wall was anchored to the retroperitoneum. This is the first report to show that rectal prolapse can be endoscopically improved and that an OTSC system might be a viable alternative method for managing inoperable rectal prolapse.
