Endoscopic Examination for Fistula

: In 15 postoperative fistula cases, we performed endoscopic examination (fistuloscopy) and studied the clinical significance. The inside of the fistula was easily observed after irrigation with physiological saline. The drain was extubated in 6 cases in which cavities without abscesses were recognized. In a case of pancreatic fistula, the fistula was temporarily closed using fibrin glue. Re-operation was performed in a case in which recurrence of cancer was recognized by biopsy. On the other hand, in 9 cases in which cavities with abscesses were recognized, foreign bodies, such as suture threads, which were sources of infections were removed. Moreover, the drain was removed to the effective site, and the fistula then irrigated repeatedly. Consequently, with the exception of a death due to cancer and a case complicated by osteomyelitis, the fistula was closed in all cases. Fistuloscopy is a safe and easy technique. In addition, the method, which is less stressful for the patient, is considered to be effective for the examination and treatment of fistulas.
