Elevation of Pancreatic Enzymes in Gallbladder Bile Associated with Heterotopic Pancreas. A Case Report and Review of the Literature
Context This is the first report associating heterotopic pancreas in the gallbladder and elevated pancreatic enzymes in bile. Case report A 60-year-old woman underwent abdominal ultrasonography at a medical check-up, revealing a nodular protrusion at the neck of the gallbladder. It seemed likely to be a lymph node, but we could not exclude the possibility of gallbladder cancer. In order to make a correct diagnosis, laparoscopic cholecystectomy was successfully performed. Pathological examination revealed heterotopic pancreatic tissue in the gallbladder wall. In addition, we detected elevated levels of amylase and lipase in gallbladder bile. Conclusions Preoperative diagnosis of heterotopic pancreas in the gallbladder is difficult. However, an increase of pancreatic enzymes in gallbladder bile may potentially play an important role in the occurrence of acalculous cholecystitis and biliary cancer. We need more accumulation of cases to know the true significance of this anomaly.
