Abstract

BACKGROUND:

Infestation with Ascaris lumbricoides is seen worldwide. Recently, there has been much interest in the pancreatic-biliary complications of Ascaris infection. In this study, we present our experience of 300 patients seen in a tertiary referral center.

MATERIALS AND METHODS:

Case charts of patients seen in the Department of Gastroenterology, University of Damascus, Syria, were analyzed, retrospectively, over a 5-yr period (September of 1988 to August of 1993). During this period, 1666 endoscopic retrograde cholangiopancreatographic studies were performed and pancreatic-biliary ascariasis was diagnosed in 300 patients (18%).

RESULTS:

The most common presenting symptom was abdominal pain, seen in 98% of patients (294 patients). Complications observed were ascending cholangitis (48 patients; 16%), acute pancreatitis (13 patients; 4.3%), and obstructive jaundice (4 patients; 1.3%). History of worm emesis was present in 25% of patients (76 patients). Most patients (240 patients; 80%) had previously undergone a cholecystectomy or an endoscopic sphincterotomy (232 patients; 77%). Worms were successfully extracted endoscopically in all except two patients, and there were no procedure-related complications.

CONCLUSIONS:

In endemic countries, ascariasis should be suspected in patients with pancreatic-biliary disease, especially if a cholecystectomy or sphincterotomy has been performed in the past. Endoscopic management results in rapid resolution of symptoms and prevents development of complications.
