The use of ERCP in the study of patients with hepatic echinococcosis before and after surgical intervention.
BACKGROUND
Biliary tree involvement is the most common complication of hydatid liver disease, which is difficult to detect and manage.


METHODS
During the last 7 years, we examined by ERCP 26 cases with echinococcal liver involvement. Indications in the preoperative group included cholangitis in 6 cases, right-sided hypochondralgia involving 4, preoperative assessment in 4, and icterus in 1 case. In the postoperative group, the indications for ERCP were cholangitis in 5 cases, external biliary fistulas in 5, and biliary colic in 1 case.


RESULTS
ERCP findings in the preoperative group included external bile duct compression in 11 cases (73.3%), biliary fistula affecting 3 (20%), and echinococcal remnants within the common bile duct in 1 case (6.6%). With regard to the postoperative group, biliary fistula formation was detected in 6 cases (54.5%), echinococcal remnants within the common bile duct in 4 (36.3%), and external bile duct compression involving 1 case (9%). Endoscopic sphincterotomy was successfully performed in 13 patients in both groups. No serious complications were encountered.


CONCLUSIONS
ERCP is a safe and helpful preoperative or postoperative tool that aids in the diagnosis and often the treatment of echinococcal liver disease with involvement of the bile ducts.
