一個三個月大的女性病患因一天周邊循環不良與臉色蒼白被診斷為先天性腸繫膜缺陷併腹內疝氣。腹部X 光顯示腸環與腸阻塞性的擴大。側邊的腹部X 光顯示嚴重的氣液分層。腹部的超聲波顯現擴張與充滿液體的腸環。腹部的斷層掃瞄顯現瀰漫性擴大的小腸環。先天性腸繫膜缺陷併腹內疝氣因此被診斷。住院後，安排剖腹探查手術，腸切除與小腸部分切除。術後包括抗生素與傷口的照護。其後，每個星期的門診追蹤。一個月後，病人的日常活力與飲食狀況皆回復到原來未發病前的地步，沒有腸阻塞的現象或症狀再被發現。

A 3-month-old female patient suffering from poor peripheral circulation and paleness for 1 day was diagnosed with a congenital mesenteric defect with internal herniation. A plain abdominal xray revealed dilatation of bowel loopswith ileus,while a lateral abdominal x-ray demonstrated the presence of several air-fluid levels. Abdominal ultrasonography revealed dilated, fluid-filled bowel loops. Abdominal CT revealed diffuse dilatation of the small-bowel loops. These findings led to the diagnosis of a congenitalmesenteric defect with internal herniation. Exploratory laparotomy with segmental resection of the small intestine and an enterostomywas performed. Follow-up involved weekly visits to our outpatient department. The patient's daily activities and feeding status had returned close to normal after 1 month. No further signs of ileus were noted thereafter.
