Annular pancreas is a rare congenital anomaly in which a thin band of pancreatic tissue partially or completely surrounds the duodenum. It is challenging to diagnose due to its variable clinical presentation. Approximately two-thirds of patients have no symptoms in their lifetime, and most symptomatic cases are seen in neonates and infants. Read More

Background: Portal annular pancreas (PAP), also called circumportal pancreas, is a congenital pancreatic anomaly in which the portal and/or mesenteric veins are surrounded by pancreatic parenchyma [1,2]. Joseph et al. classified PAP into three types (according to the fusion pattern of the pancreatic parenchyma and ductal system [1]), each of which they subdivided (based on the relation to the portal confluence) into the suprasplenic, infrasplenic, and mixed type [1,3].

VACTERL Syndrome affects multiple body systems and can include various anomalies of the Vertebral column, Anus and/or rectum, heart (Cardiac), Tracheo-Esophagus, kidneys (Renal), and Limbs. Patients with VACTERL syndrome are at increased risk of having a congenital duodenal obstruction that may be extrinsic in the form of an annular pancreas or intrinsic in the form of duodenal atresia, stenosis or web. Simultaneous presentation of both the annular pancreas and duodenal web is a rare clinical entity and typically presents in neonates. Read More

Duodenal stenosis and atresia are some of the most common forms of congenital bowel obstruction. The gold standard approach to treatment is duodenoduodenostomy, while rare, gastrojejunostomy and duodenojejunostomies may still be used. We report a case of a 7-year-old male presenting with annular pancreas with duodenal stenosis that was diagnosed at birth as primary duodenal atresia and repaired by gastrojejunostomy with a Braun enteroenterostomy.

Congenital anomalies of the liver, biliary tree and pancreas are rare birth defects, some of which are characterized by a marked variation in geographical incidence. Morphogenesis of the hepatobiliary and pancreatic structures initiates from two tubular endodermal evaginations of the most distal portion of the foregut. The pancreas develops from a larger dorsal and a smaller ventral outpouching; emergence of the two buds will eventually lead to the fusion of the duct system. Read More
