Endoscopic examination for pancreatic fistula.

We have conducted endoscopic examination in 5 cases of postoperative pancreatic fistula, and discuss its clinical significance. The examination provided not only an observation of the fistula but also opportunity to irrigate the fistula for removal of foreign substances. The biopsy permitted histological examination for necrotic substances and the fistulous wall. Endoscopy made it easy to introduce a drain into the affected site and to judge when to remove the drain. Closure of the fistula was also attainable using fibrin glue. Consequently, the fistulas were closed within 1 month from the examination in all cases but one, in which death resulted due to carcinoma. The examination is an easy and safe technique.
