摘　　要：阐述幽门前瓣膜症的病因、分类及手术方式的选择。１９８８～１９９４年收治４例均为有孔瓣膜型，症状于出生１个月后出现。Ｂ超检查示幽门完全梗阻１例，不完全梗阻３例，均未见幽门肿块。ＧＩ检查常先行胃肠减压等治疗后继用少量造影剂检查，完全和不完全梗阻各１例，无征象２例。瓣膜位于胃窦部１例行单纯瓣膜切除术；幽门部２例行瓣膜切除加幽门成形术；合并胃溃疡１例行胃部分切除毕Ⅰ式吻合术。随访１～７年均无异常。本病罕见，症状出现的迟早取决于梗阻的严重程度。ＧＩ检查中注意胃肠减压等治疗对造影的影响。Ｂ超和内窥镜检查对确立诊断有重要价值。应根据瓣膜的解剖部位及合并症选择手术方式。From 1988 to 1994,4cases with prepyloric fenestrated membrane were treated. The symptoms presented in 1st month of life. B-ultrasonography demonstrated complete obstructed pylorus in l case and partial obstruction in 3.No pyloric mass was found. A thin mixture of barium meal in empty stomach revealed complete obstruction(1), partial obstruction(1) and no obstruction(2).Of them, one case was treated by simple membrane resection, 2 cases by resection and pyloroplasty, and the one complicated by gastric ulcer underwent partial gastrectomy and gastroduodenostomy. All of them were followed up for 1-7 years without any complications.Conclusion : Prepyloric membrane is rare. Its clinic manifestation depends on the degree of obstruction. B-ultrasonography and endoscopy are important to the diagnosis.
