Endoscopic Retrograde Panereatocholangiography (ER CP) has gained popularity for direct cholangiography. In this paper the laparoscopic cholangiography which was performed to the patients whose gallbladder was not visualized by ERCP was evaluated. ERC was carried out to 123 patients. In 88 patients whose bile ducts were sufficiently opacif ied by ERC, 27 (30.70) shows no visualization of gallbladder. Among the patiens whose gallbladder was not visualized by ERC, abnormality of the gallbladder, for example cholecystoli-thiasis or atrophic cholecystitis, was comf irmed by operation and laparoscopy in 95.90. Combied examination of ERC and laparoscopic cholangiography was performed to the 20 patients, who had nonvisualized gallbladder or nonopacification of the bile duct by ERC. By combined examination, correct diagnosis was obtained in 90%. There was no serious side effects of the laparoscopic choiangiography in our hospital. When there is nonvisualization of the gallbladder by ERC, combined examination of ERC and laparoscopic cholangiography is valuable method for the accurate preoperative diagnosis.
