Esophageal anastomotic leaks: preliminary results of treatment with balloon dilation.

Disruption of a cervical esophagogastric or esophagocolonic anastomosis shortly after surgery is a common complication, and fistula drainage from the leaking anastomosis may be prolonged. Narrowing of the anastomosis apparently contributes to the development and maintenance of the fistula. Fluoroscopically guided balloon dilation of anastomotic strictures was performed in three patients with anastomotic leaks. Preliminary results suggest that the procedure is safe and promotes healing of the fistula.
