The role of endoscopic retrograde cholangiopancreatography in the management of hepatic hydatid disease.

BACKGROUND AND STUDY AIMS

Hydatid disease of the liver, and its complications, causes serious morbidity and mortality. We evaluated the role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of hepatic hydatid disease.

PATIENTS AND METHODS

This retrospective analysis includes 28 patients with hepatic hydatid disease who underwent ERCP. ERCP was performed preoperatively in 11 patients, for acute cholangitis (n =7), acute pancreatitis (n = 1) and right upper quadrant pain (n = 3), and in eight asymptomatic cases to search for fistulae between the cyst and the biliary tree. In a further nine patients ERCP was performed for early (< 30 days; n = 7) and late (n = 2) postoperative biliopancreatic problems.

RESULTS

In all seven patients with cholangitis preoperative ERCP with EST and ductal clearance of daughter cysts and debris led to substantial clinical improvement, including four acutely ill elderly patients who stabilized and were later able to undergo surgery. EST in two of the three patients with pain who had papillary stenosis led to resolution of the abdominal pain. Six of the seven postoperative fistulae could be successfully treated endoscopically using EST.

CONCLUSIONS

This study demonstrates the usefulness of ERCP in symptomatic patients with hepatic hydatid cysts; EST enables clearance of the common bile duct and allows healing of postoperative fistulae in the majority of patients. We do not, however, recommend performing routine preoperative ERCP in asymptomatic patients with the disease.
