During cholecystectomy for symptomatic gallstone disease in a 72-year-old lady, operative cholangiography demonstrated an opacified pancreatic duct surrounding the duodenum (figure 1). Abdominal CT revealed an annular pancreas (figure 2). This rare, congenital anomaly comprises a ring of pancreatic tissue that encircles the second part of the duodenum in 74% of patients.1 This embryologic migration fault affects approximately 1 in 20 000 newborns.1 Although rare, it may become symptomatic in adults and may be associated with peptic ulceration, pancreatitis, or duodenal obstruction. Gastrojejunostomy is the preferred method of treatment for persistent duodenal obstruction.2 Resection is recommended only when it is associated with pancreatolithiasis leading to chronic pancreatitis.
