Abstract
Biliary taeniasis is uncommon in clinical practice. We report two cases in our hospital. The first patient was diagnosed with acute biliary pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) showed a white, flat, segmented 1-cm-wide tapeworm drilling into the duodenal papilla that was identified as Taenia saginata. After tapeworm removal, bile duct sweeping, and anthelmintic therapy, the patient recovered uneventfully. The second patient was diagnosed with acute cholangitis and multiple stones in the common bile duct and gallbladder. Emergency ERCP showed no tapeworm in the duodenum. During a subsequent ERCP 6 days later, a flat tapeworm, also T. saginata, was identified drilling into the duodenal papilla. We review five patients cases with acute acalculous cholecystitis or cholangitis caused by T. saginata or Taenia solium, and 1 patient with T. saginata drilling into the T-tube. Taeniasis should be taken into consideration when dealing with biliary and pancreatic disease.
