Histological studies were conducted on 4 patients with intestinal atresia due to intrauterine intussusception. This atresia is characterized by a polypoid lesion as the remnant of the invaginated and necrotized intestine in the distal intestinal lumen. As the result of the histological survey in the affected intestine, we tentatively classified this atresia into two types, type A and B. In type A, the polypoid lesion is observed at the blind end, with relatively good preservation of the structure of the intestine. In type B, the polypoid lesion is located apart from the blind end, and the lesion is markedly necrotic. The interruption of intestinal blood flow seemed to be more severe in type B than in type A.
对4例因宫内肠套叠导致肠闭锁的患者进行了组织学研究。这种闭锁的特征是在远端肠腔内有一个息肉样病变，为套入并坏死的肠管残余。通过对受累肠段的组织学检查，我们初步将这种闭锁分为A、B两型。A型在盲端可见息肉样病变，肠结构保存相对较好。B型息肉样病变位于远离盲端处，且病变明显坏死。B型肠血流中断似乎比A型更严重。
