Surgical evaluation of endoscopic retrograde cholangiography for XXXX .

@entity1 @entity177 @entity292 @entity253 @entity9317
We attempted to clarify the surgical usefulness and limitation of endoscopic retrograde cholangiography (ERC) by comparing with drip infusion cholangiography (DIC). ERC was carried out on 144 @entity1 with clinical symptoms of @entity253 . The success rate was 71.5 per cent. Indications for surgery were found in 83.9 per cent of the @entity1 with positive ERC findings and in 50.5 per cent of the @entity1 in whom ERC was successful. The false positive rate in ERC, as revealed during the surgery was 2.3 per cent. Failure of ERC occurred in 41 @entity1 . @entity177 was attributed to para-vaterian diverticulum in 11, post-gastrectomy states in 5, the @entity9317 covered by a polyp or a large fold in 2, and @entity292 in 1. The failure of cannulation in 22 could not be clearly defined. As ERC was successful in 3 out of 9 @entity1 in whom this approach was unsuccessful in the first trial, ERC should probably be repeated if such was indeed required pre-operatively. Diagnostic significance of DIC before ERC revealed that such plays a definite role in screening @entity1 .
