An 18-year-old man was admitted to a local hospital with abdominal pain and bloody stool. Upper and lower gastrointestinal endoscopy failed to show any bleeding sites; however, an angiography of the superior mesenteric artery done on hospital day 4 showed an abnormal artery with an aneurysm, branching from the ileal artery. This artery was thought to be the vitellointestinal artery, a feeding artery of Meckel diverticulum. After embolization, he was transferred to our hospital, where we performed emergency laparotomy with partial resection of the ileum, including a bleeding Meckel diverticulum. Pathological examination revealed ectopic gastric mucosa and peptic ulceration, which we assumed was the origin of the bleeding. The patient had an uneventful postoperative course. Visceral artery aneurysms are rare but important vascular lesions because of their potential for fatal rupture. Although a minimally invasive procedure can be performed for a vitellointestinal artery aneurysm in patients with asymptomatic Meckel diverticulum, we treated our patient surgically because he presented with hemorrhagic shock and had been unresponsive to an H2-receptor antagonist.

A Case of Rupture of the Thoracic Lower Esophagus Found Out after Blunt Trauma

慢性関節リウマチでメトトレキセートを内服中の71歳の女性が, 昼食後に入浴し, 立ち上がった際に意識を消失して転倒した. 意識は回復したが, 強い胸痛と呼吸苦が出現したため, 当院へ搬入された. 胸部CTで左気胸, 左胸腔内の食物残渣状の胸水貯留, 胸部下部食道壁の肥厚を認めたが, 外傷性変化は見られなかった. 胸腔ドレナージ後に内視鏡検査で胸部下部食道に穿孔を確認し, 緊急手術を行った. 開胸すると食物残渣を混じた胸水が貯留しており, 胸部下部食道左側壁に3.5cmの穿孔を認めた. 1期的縫合閉鎖, 洗浄, ドレナージを行った. 術後食道造影X線検査では縫合不全や狭窄はなく, 食事摂取も良好であった. 創感染と日常生活動作の低下により入院が長期化したが, 術後58日目に退院した. 自験例では意識消失・転倒に先行した腹腔内圧上昇につながる症状はなく, 食道破裂の成因は転倒による圧上昇と推測された.鈍的外傷では食道破裂も念頭におく必要がある.

症例は心房細動とうっ血性心不全の既往がある79歳の男性で, 腹痛を主訴に近医を受診した. 超音波検査で骨盤内に腹水を認めたが, 腹膜刺激症状と炎症所見がなく, 保存的治療を行った. 翌日, 腹膜刺激症状と炎症反応を認め, 当科に入院した. 急性虫垂炎による汎発性腹膜炎を疑い, 手術を行った. 虫垂腫大と骨盤腔内の膿性腹水を認め, 虫垂切除術を行った. 腹水からBacteroides thetaiotaomicronが検出された. 摘出虫垂粘膜に炎症を認めなかった. 高CEA血症と貧血を認めたため, 消化管精査を行い, 上行結腸癌が発見された. 23日目に結腸右半切除術を行った. 腫瘍の穿孔, 膿瘍形成を認めなかった. 腫瘍は高分化腺癌で, ss, n (-), P0, H0, M (-), stage IIであった. 術後経過は良好で, 17日目に退院した. 自験例は心不全による腹水に大腸癌の壊死部または口側の浮腫状の腸管壁からバクテリアルトランスロケーションが起こり, 特発性細菌性腹膜炎を来したと推測された.
