Abstract

BACKGROUND/AIMS: Cannulation failure to biliary tract has been reported in 10% of patients who are performed diagnostic and therapeutic ERCP. Infundibulotomy by use of needle knife is cutting a bulbar part of protruding papilla, which has merit to avoid complete destruction of sphincter of Oddi and serious side effects than general precutting method. We want to know effectiveness and safety of infundibulotomy.
METHODS
From January 1997 to December 1998, 36 patients who failed cannulation over three times trial by conventional method are included to this study. We compared the success rate of cannulation and procedure related complication according to bile duct dilatation, periampullary diverticulum and shape of ampulla of Vater.
RESULTS
1) Success rate of cannulation to bile duct is 81% (29/36). 2) All patients in group of bile duct dilatation (14) are succeed to cannulation, which is significantly high compare to other group (p=0.0288). 3) There was no statistical difference in success rate according to presence of periampullary diverticulum. 4) In groups of bulging prominent papilla are succeed in 23 among 26 patients, which is tendency of high in patients than other group (p=0.0760). 5) Total occurrence of procedure related complication was 33% (12/36). 6) The complication rate was not different in two groups according to cannulation success 7) The complication rate was tendency of high in patients without bile duct dilatation (p=0.0756).
CONCLUSIONS
Infundibulotomy by use of needle knife is effeetive and safe cannulation method to patient who failed cannulation to bile duct. Success of cannulation is low and occurrence of complication is tendency of high in patient without bile duct dilation, which propose endoscopists attention in selection of indications.
