Eighty-two post-operative choledochoscopy for 43 patients were performed through the fistula after T-tube was removed. Post-operative choledochoscopy was formerly carried out in the X-ray room so that selective cholangiography with insertion of a thin teflon tube or back-flushing catheter into the desired locations could be immediately obtained whenever any doubt in endoscopic diagnosis existed. Selective cholangiography in conjunction with choledochoscopy seems to be the most reasonable approach as a diagnostic test, because cholangiography alone is usually inconclusive.Moreover, post-operative choledochoscopy can be performed repeatedly if T-tube fistula is kept patent and is useful procedure for observation of biliary tracts as well as treatment for retained biliary calculi and intrahepatic calculi. The importance of employing post-operative choledochoscopy as an adjunct to conventional roentgenological examination was strongly advocated.
