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.
腔内十二指肠憩室（IDD）是一种罕见的先天性异常，它是胚胎前肠再通不完全的结果，导致十二指肠腔内留下有孔的膜。多年的蠕动作用于该膜导致憩室形成。大多数患者无症状，而一些患者可能有腹痛、腹胀或饱胀感。罕见的并发症包括胃肠道出血、梗阻、胰腺炎和胆管炎。我们报告2例内镜检查结果与部分梗阻性症状性IDD相符的病例。
