Abstract:
Objective To improve the successful rate of endoscopic biliary drainage. Methods The experience of biliary drainage with duodenoscope for biliary obstruction from January 1998 to September 2001 was reviewed retrospectively. Endoscopic naso -biliary drainage (ENBD) , endoscopic retrograde biliary drainage (ERBD) and endoscopic metal biliary endoprothesis (EMBE) were performed in 242 cases, 43 cases and 35 cases respectively. Results Of 320 cases with biliary obstruction, 305 received successful drainage under endoscopy and 15 cases failed. Ten cases with ENBD failed but got successful drainage after modulating the site of naso-biliary tube or reinserting another tube. For 3 cases failed with ERBD, we chose plastic stents with appropriate length for 2 cases to achieve fluent drainage and percutaneous transhepatic biliary drainage (PTBD) was managed for another case after endoscopic management failed. For 2 cases with EMBE failed, one stent couldn' t exceed the tumor stricture site and one was obstructed by tumor implantion at one month after EMBE. Either a metal stent or a plastic stent was replaced through previous prothesis in these two failed cases. Conclusions The effect of endoscopic biliary drainage for biliary obstruction is definite. Mostly the drainage failure can be avoided as early as possible by analyzing the causes and taking some corresponding measures to correct it.
