Combined endoscopic approach for the management of a difficult recto-sigmoid anastomotic stricture.

A 48-year-old woman underwent an emergency laparotomy for a perforated diverticular abscess. At operation, a peritoneal lavage was carried out, but no colonic resection was undertaken. Subsequently, she developed recurrent sepsis and underwent a second laparotomy. The patient was referred to our institution for a definitive left hemicolectomy and diverting loop colostomy. Before closing the colostomy, a contrast enema revealed obstruction of the lumen at the anastomotic site. This was refractory to conventional colonoscopic dilatation. A simultaneous endoscope was passed through the distal loop of the colostomy in addition to a conventional approach. A defect was created that allowed passage of a guide-wire and balloon dilator. One week later, the anastomosis remained patent, and the colostomy closed. The patient remains well, with normal bowel function. This novel combined endoscopic approach for dealing with colonic stenoses avoids the higher morbidity and mortality associated with an open surgical procedure.
