Gas explosion caused by argon plasma coagulation of colonic angiodysplasias

Gas explosion caused by argon plasma coagulation of colonic angiodysplasias.

established tool to treat lesions of the gastrointestinal mucosa, such as angio− dysplasias [1]. Cases of colon perforation after gas explo− sion caused by APC have been recorded since 1976 [2], especially after prepara− tion with mannitol [3], which seemed to increase hydrogen gas production. Newer data suggest that stools remaining in an incompletely cleaned bowel may be the main cause for ex...

Argon plasma coagulation

Argon Plasma Coagulation (APC) is an application of gas discharges in argon in electrosurgery, which is increasingly used especially in endoscopy. The major application fields are haemostasis, tissue devitalization and tissue reduction.This review describes the physics and technology of electrosurgery and APC. Some characteristics of the argon discharge are shown and discussed, and thermal effe...

アルゴンプラズマ凝固法(argon plasma coagulation: APC)は外科手術時の臓器切断面止血法のひとつ として用いられてきたが,内視鏡用のアプリケータが 開発されてからは,消化器内視鏡分野で新たな止血 ・凝固法として注目を集めている. APCはアルゴン ガスを噴射し,その流れに高周波電流を重ねた非接 触型高周波凝固法で,アルゴンガスはプローブ先端 でイオン化されアルゴンプラズマ流となって組織に 到達し,表面を凝固する.その適応は止血処置の他, 腫瘍焼灼や食道静脈瘤の地固め療法にも使用され ている.特徴としては,操作が簡便で短時間に広範 囲を浅い深度で凝固できることがあげられる.今回, 重篤な基礎疾患を合併しているため内視鏡的粘膜切除 (Endoscopic mucosal resection: EMR),外科手術が 施行困難な食道表在癌に対しAPC治療を施行した ...

Minute perforation after argon plasma coagulation for management of small colonic polyps.

month history of chronic constipation and abdominal bloating. Because of concern about a colorectal lesion, colonoscopy was done and hundreds of small polyps were found throughout the colon, most being less than 4mm in diameter. Some of the bigger polyps were removed by polypectomy andwere found at pathologic examination to be tubular adenoma. As the patient was unwilling to undergo a rectum-pr...
