Non-Obstructed Volvulus as a Complication of Midgut Malrotation in Adult: Report of a Case

成人先天性中腸旋轉不良併發非阻塞性之腸扭結:一病例報告

摘要


先天性中腸旋轉不良併發腸扭結常見於嬰兒,卻少見於成人。大部份成人之病例多於偶然中發現且少有症狀。報告一例55歲女性主訴間歇性腹部絞痛有兩個月,經電腦斷層攝影,小腸攝影,及血管攝影在術前診斷為腸扭結。於開刀中發現小腸沿著上腸繫膜動脈和靜脈的柄,順時針轉了540度。扭轉的小腸纏繞在不完全被支撐的腸繫膜的柄。因為小腸並沒有壞死,在把扭結的小腸復原之後,進一步把腸繫膜的柄擴大,並且把盲腸和小腸分別固定於右下及左上腹壁,以避免再發生扭結。病人恢復得很好,而且在追蹤的三個月中不再有腹痛發生。

並列摘要


A 55-year-old woman with a midgut malrotation-induced volvulus had a history of intermittent, colicky abdominal pain for 2 months. Small bowel series showed a ”cork-screw” appearance and abdominal CT scan showed a ”whorl like” mass pattern, suggestive of volvulus. Angiogram revealed a twist of jejunal arteries along the superior mesenteric artery axis (barber pole sign). At laparotomy, the jejunum was found to twist 540 degrees clockwise around the pedicle of superior mesenteric artery and vein. Coils of small intestine wrapped around the root of an incomplete anchored mesentery. The viability of small bowel was not compromised. After reduction of volvulus, the mesenteric pedicle was broadened and a stabilization procedure was performed. The patient had a good recovery and has been symptom free for 3 months after operation.
