EXAMINATION OF THE ENDOSCOPIC NASO- GALLBLADDER DRAINAGE FOR ACUTE CHOLECYSTITIS

Abstract

We retrospectively studied the efficacy and problems of endoscopic naso- gallbladder drainage (ENGBD) for acute cholecystitis in 153 cases. We mainly chose those patients (about 34.6%) who were taking an anticoagulant and those patients (about 22.9%) whose acute cholecystitis was suspected of being complicated with gallbladder cancer. Technical success was obtained in about 87.6% and the salvage rate was about 98.0%. The period required for symptom improvement was about 3.2 days. As a whole, complications occurred about 7.2% and we experienced a cystic duct perforation. In addition, in 3 cases (about 1.96%) gallbladder cancer was preoperatively identified and we were thus able to avoid additional excision. The operation was successfully completed in an average of around 25.1 min which meant it could be accomplished in a relatively short time. We can expect further improvement in both the surgical equipment and technical skill, but we believe it is a currently effective method with appropriate patient selection.
