Endoscopic glue injection for closure of the fistula at POD40 (a), and an oral contrast enhanced CT scan one week, at POD48, after endoscopic glue injection (b and c). An about 5 mm fistula tract opening was found via endoscopic examination (dashed line, a), and was closed by Histoacryl® and Lipiodol® injection. The following oral contrast enhanced CT scan one week later still showed a minor leak (asterisk, b and c) and a more enlarged size of the pseudocavity. Abbreviation: POD, postoperative day; CT, computed tomography
