Bowel Perforation by a Peritoneal Tube 20 Years after a Ventriculoperitoneal Shunt: A Case Report

Kenichi Ishibayashi, Yusuke Sakimura, Hiroki Tawara, Kengo Hayashi et autres

症例は45歳の女性で,20年前にくも膜下出血による水頭症に対して脳室腹腔シャント(ventriculoperitoneal shunt;以下,VPSと略記)挿入術が施行された.意識障害があり当院を受診し頭部CTで脳室拡大を認め,脳室ドレナージが施行された.VPSの閉塞が疑われ施行した全身CTでVPSチューブが上行結腸を穿通しており,治療目的に当科紹介となった.開腹するとチューブ状の繊維性被膜が上行結腸に付着しており,繊維性被膜を全周性に剥離するとVPSチューブが同定できた.VPSチューブを結紮,離断し,腸管に穿通しているカテーテルは抵抗なく抜去できた.腸管の瘻孔は縫合閉鎖した.VPSチューブ腹側端は髄液漏出を確認し,繊維性被膜内から出さずに閉腹した.術後第9病日に脳室ドレーン感染からの髄膜炎を来し,VPSチューブの全抜去を施行した.まれなVPSの消化管穿通の1例を経験したので報告する.

A Case of Intra-abdominal Abcess following a Pancreatic Fistula after Gastrectomy Treated with Endoscopic Ultrasound-guided Transgastric Drainage

Kenichi Ishibayashi, Toshikatsu Tsuji, Daisuke Yamamoto, Hirotaka Kitamura et autres

胃癌術後膵液瘻は重篤な術後合併症である.今回,胃切除後膵液瘻に伴う腹腔内膿瘍に対し超音波内視鏡下経胃ドレナージを行った1例を経験したので報告する.症例は67歳,女性.胃癌(cT2N0M0,cStage I)に対して腹腔鏡下幽門側胃切除術を施行した.術後第4病日に38.6度の発熱と背部痛を認め,造影CTを施行したところ,膵の腫大と周囲の脂肪織濃度の上昇,輸入脚周囲の液体貯留を認めた.保存的加療にて症状は軽快せず,保存的加療開始28日目に造影CTを施行すると,貯留していた液体は被包化され膿瘍を形成していた.体表との間に介在する腸管により経皮的なドレナージは極めて困難であったが,膿瘍壁と胃壁が接していたため超音波内視鏡下経胃ドレナージ術を施行した.解熱と膿瘍の著明な縮小を認め,その後経過は良好である.
