A 38-year-old man with a history of recurrent pancreatitis of undetermined origin was re-admitted with vomiting and epigastric pain. A decision was made to perform a laparoscopic cholecystectomy. At the laparoscopy, pancreatic tissue completely wrapped around the duodenum was found. A gastrojejunostomy was performed to treat the gastric outlet obstruction caused by the obstructive annular pancreas.

A 22 year-old male patient underwent laparoscopic cholecystectomy for recurrent biliary colic. Multiple macroscopic pale lesions were noted on the liver surface. Histopathology confirmed non-caseating granulomas. Serum angiotensin-converting enzyme was elevated. These findings were suspicious for extrapulmonary manifestations of sarcoidosis. Up to 10 per cent of all liver biopsy specimens are granulomas. Of these, 22 per cent are due to sarcoidosis. This is mostly asymptomatic. Up to 40 per cent of patients however present with biochemical derangement or hepatomegaly.
