症例は55歳の女性.交通事故にて腹部を強打し,当院に救急搬送された.腹部CT検査にて脾損傷による腹腔内出血と診断し,選択的脾動脈塞栓術を施行した.受傷後14日目より腹痛が出現し,増強するため,受傷後19日目に腹部CT検査を行った.受傷時の右下腹部圧痛点に一致する限局性の回腸壁の肥厚,狭窄を認め,腹部外傷による遅発性小腸狭窄と考えられた.保存的加療を行ったが軽快せず,腹腔鏡補助下手術を行った.回盲部より約30cmの回腸に約10cmにわたる肥厚性狭窄を認め,小腸部分切除を施行した.病理組織所見では広範な潰瘍形成と特に粘膜下層での線維増生を認めた.外傷後遅発性小腸狭窄は稀ではあるがCTによる術前診断が可能であり,治療として腹腔鏡補助下手術が有用な選択肢の1つと考えられた.
A 55-year-old woman was brought to our hospital by ambulance because of abdominal pain after a motor ve-hicle accident. Diagnosis of intra-abdominal bleeding caused by splenic injury was made based on CT scan, and the patient underwent selective splenic artery embolization. Fourteen days after the accident, she began to have abdominal pain, which became increasingly severe. A CT scan 19 days after the accident showed an ileal loop with a thickened wall and narrow lumen in the right lower quadrant, which was consistent with the site of in-jury in the previous accident, indicating delayed post-traumatic intestinal stenosis.
