Endoscopic Management of Refractory Benign Colorectal Strictures

Abstract

In colonoscopic study, benign colorectal strictures with or without symptomatic pain are not rarely encountered. Benign colorectal stricture can be caused by a number of problems, such as anastomotic stricture after surgery, inflammatory bowel disease, postendoscopic submucosal dissection, diverticular disease, ischemic colitis, and so on. There are various modalities for the management of benign colorectal stricture. Endoscopic balloon dilatation is generally considered as the primary treatment for benign colorectal stricture. In refractory benign colorectal strictures, several treatment sessions of balloon dilatation are needed for successful dilatation. The self-expandable metal stent and many combined techniques are performed at present. However, there is no specific algorithmic modality for refractory benign colorectal strictures.

Endometriosis: A Rare Cause of Large Bowel Obstruction

“…The incidence of AS after colorectal surgery for endometriosis has been found to range between 2 and 5% [16][17][18], but in a recent series of 113 colonic resections there was a rate of 12%, a higher incidence than for other indications than endometriosis. The etiology of AS is rarely known and seems to be multifactorial [19].…”

Endoscopic radial incision and cutting method for refractory stricture of a rectal anastomosis after surgery

“…Benign colorectal strictures occur mainly as a result of surgical resection [1]. Especially when a stricture is located in the rectum, it may cause severe symptoms, for which several therapeutic options are available: endoscopic balloon dilation (EBD) [2], placement of a self-expandable metal stent [3], revisional surgery, and palliative colostomy.…”

Transanal anorectal stricturoplasty using the Heineke–Mikulicz principle: a novel technique

“…Dilatation has been described using a Hegar's dilator, an endoscopic balloon dilator, Tucker bougie and Lister's urethral dilator for high rectal strictures . Balloon dilatation is the most widely reported method and results in quick, simple and adequate treatment for many patients, but 30–40% require multiple dilatations owing to recurrence of stenosis .…”
