CONTEXT The pancreas is formed by ventral and dorsal pancreatic buds which arise from the endodermal lining of the gut. When the duodenum rotates to the right, the ventral pancreatic bud migrates dorsally and finally come and lie below the dorsal pancreatic bud. The developmental errors in the rotation of these components lead to annular pancreas. CASE REPORT We report a rare type of the inco...

DESCRIPTION A preterm neonate weighing 1360 g was born at 33+2 weeks’ gestation with severe polyhydramnios. She was transferred, directly after delivery, to our neonatal intensive care unit presenting with distended upper abdomen and vomiting. A plain film of the abdomen (figure 1) was performed with the suspicion of duodenal atresia and showed a markedly distended stomach (S) and proximal duod...

Congenital duodenal obstruction commonly occurs due to malrotation, atresia, stenosis and annular pancreas in decreasing order of frequency. Besides this, duodenal obstruction may occur due to high fixation of duodenojejunal junction or due to hyperfixation bands at duodenojejunal flexure(l-5). We are presenting three cases in which duodenal obstruction occurred in the presence of normally rota...

Annular pancreas is a rare congenital anomaly in which the pancreatic tissue forms a complete or partial ring around the descending duodenum. Findings in an autopsy series indicated a prevalence of 5 to 15 cases per 100,000 adults. There are two peaks of presentation, first in infancy (52%) and second in the fourth decade of life (48%). Opening of the cystic duct to the papilla without combinig...
