Two Cases of Intraluminal "Windsock" Diverticula Resulting in Partial Duodenal Obstruction

Vikram Anand et al. ACG Case Rep J. .

Abstract

An intraluminal duodenal diverticulum (IDD) is a rare congenital anomaly that is the result of incomplete recanalization of the embryologic foregut leaving a fenestrated membrane within the lumen of the duodenum. Years of peristalsis acting on the membrane result in the formation of a diverticulum. Most patients are asymptomatic, while some may have abdominal pain, bloating, or fullness. Rare complications include gastrointestinal bleeding, obstruction, pancreatitis, and cholangitis. We present 2 cases with endoscopic findings consistent with partially obstructing symptomatic IDD.
