Endoscopic management of colocolonic anastomotic dehiscence: a case report.

We describe the case of a woman who developed a perianastomotic collection after colocolonic anastomosis for restoration of bowel continuity, consistent with an anastomotic dehiscence. Endoscopy revealed a stenotic anastomosis inaccessible to vacuum therapy. A fully endoscopic strategy was pursued, combining internal drainage of the collection with double-pigtail stents and treatment of the stenosis through balloon dilation. The patient showed a favorable course, with complete resolution on follow-up. This case underscores the feasibility, safety, and efficacy of endoscopic management of colocolonic anastomotic dehiscence, highlighting the importance of simultaneously addressing associated stenosis.
