A rare case of duodenojejunal intussusception causing biliary obstruction during pregnancy.

Intussusception is an uncommon cause of intestinal obstruction in adults and rarely encountered during pregnancy. Duodenal intussusception is particularly rare due to the fixed position of the duodenum. We report a unique case of duodenojejunal intussusception in a pregnant woman at 28 weeks of gestation, who presented with symptoms mimicking acute pancreatitis complicated by biliary tract obstruction. To our knowledge, this is the first description of such a presentation without an identifiable lead point, illustrating the diagnostic value of imaging and the importance of considering rare etiologies in the differential diagnosis of abdominal pain during pregnancy.
