◆要旨:患者は57歳,女性.高度肥満に対し腹腔鏡下スリーブ状胃切除術を施行した.退院後に嘔吐を認め入院した.上部消化管内視鏡検査では胃管胃角部の捩れによる狭窄を認めた.内視鏡下バルーン拡張術を施行したが奏効せず,難治性胃管狭窄と診断し術後第101病日にHANAROSTENTⓇを留置した.6週後のステント抜去後,通過障害を認めていない.スリーブ状胃切除術後の胃管狭窄に対しては,食道狭窄用バルーンやアカラシアバルーン,ステント,再手術などが報告されているが,自己拡張型・抜去可能なHANAROSTENTⓇを用いた報告は本邦初となる.スリーブ状胃切除術後の難治性胃管狭窄に対する有効な治療オプションになりうると考えられる.
A 57-year-old obese woman with a body mass index of 35.3 kg/m2 underwent laparoscopic sleeve gastrectomy. The patient was discharged from the hospital on postoperative day(POD) 5 without any complications. However, she returned to the hospital because of passage disturbance on POD 61 and 70. Endoscopy showed torsion and stenosis at the gastric angle. Two endoscopic balloon dilations failed to improve the passage disturbance. Finally, a covered, self-expandable, and retrievable stent(HANAROSTENTⓇ) was placed over the stenotic lesion on POD 101. Oral intake resumed on the day of stenting. Six weeks later, the stent was removed endoscopically according to the initial plan. The patient has remained free of any stenotic recurrence. HANAROSTENTⓇ could be an option for treating gastric stenosis after sleeve gastrectomy.
