Intraluminal duodenal “windsock” diverticulum; Case Report and discussion

Intraluminal duodenal diverticulum (IDD) is a rare developmental anomaly usually found in the second portion of the duodenum. The cause appears to be a failure of recanalization of the occluded foregut lumen of the human embryo, resulting in a fenestrated mucosal membrane [1]. A small aperture in this diaphragm will gradually cause it to elongate caudally in response to duodenal peristalsis to form the so called “wind-sock” configuration. Symptoms are nonspecific and generally depend on the degree of duodenal obstruction; 25% of cases are associated with GI bleeding. In most documented cases, IDD was diagnosed radiologically, but the value of endoscopy for diagnosis and treatment has been amply demonstrated.

Intraluminal Duodenal Diverticulum: A Rare Cause of Chronic Epigastric Pain

Despite its first identification in 1885, intraluminal duodenal diverticulum remains a rare entity and only a few case reports are found in the literature. Its diagnosis is almost always delayed due to the lack of specific symptoms and to the very vague presentation consisting of mild epigastric discomfort. However, with the aid of new diagnostic modalities and imaging, it has become easier to diagnose this entity when its symptoms persist. Finally, it can remain undiagnosed in asymptomatic patients.

Intraluminal duodenal (“windsock”) diverticulum: a rare cause of biliary obstruction and acute pancreatitis in the adult

An intraluminal duodenal diverticulum (IDD) is a rare congenital anomaly, which is a result of incomplete recanalization of the foregut lumen during embryonic development. Most patients are asymptomatic. Symptoms usually occur after the third decade of life and mainly include epigastric pain, nausea, vomiting, or bloating. Less commonly, IDD may complicate with bleeding, duodenal obstruction, or acute pancreatitis. We present a case of IDD, manifested for a first time in adult with acute biliary obstruction and mild pancreatitis after laparoscopic cholecystectomy for acute calculous cholecystitis, successfully managed with endoscopic retrograde cholangiopancreatography (ERCP).
