Giant colonic diverticula are rare entities and often present in adulthood as acute diverticulitis. The authors present a case of giant colonic pseudodiverticulum lined with uroepithelium causing bowel obstruction in a neonate. The presence of uroepithelium in a colonic pseudodiverticuium remains unexplained and to the authors' knowledge unreported. This heterotopic tissue may be a result of an embryonic rest or could be urachal in origin adhering initially to the colon and eventually detaching from the umbilicus. These lesions should be resected because of the risk of infection, perforation, or obstruction.
巨大结肠憩室是罕见的病症，常在成年期表现为急性憩室炎。本文作者报告了一例新生儿因内衬尿路上皮的巨大结肠假性憩室导致肠梗阻的病例。结肠假性憩室内存在尿路上皮的原因尚不清楚，据作者所知也未见相关报道。这种异位组织可能是胚胎残留的结果，或者可能起源于脐尿管，最初附着于结肠，最终与脐部分离。由于存在感染、穿孔或梗阻的风险，这些病变应予以切除。
