Abstract
ENBD was performed in 171 patients with pancreatic and biliary diseases between May, 1983 and March, 1988. ENBD was effective in 40 of 41 patients (97.5%) with benign obstructive jaundice, and 38 of 54 patients (70.3%) with malignant obstructive jaundice. ENBD was done with good results in all cases for biliary lavage in 51 patients who developed clogging of endoprosthesis or cholangitis, and for the prophylaxis of stone impaction after ERCP or EPT in 25 patients. Daily mean bile flow volume through ENBD catheter was 389±250ml. In biliary lavage and benign biliary drainage groups, the bile volume was greater than that in the other groups. No significant correlation between the size of ENBD catheter and bile volume was obseved Only two cases developed complications such as bleeding after EPT and clogging due to hemobilia. Above results indicate that ENBD is a safe and effective method for biliary drainage in benign obstructive jaundice, but for malignant obstruction at hepatic hilar portion, the drainage is much less effective and PTBD is better indicated.
