【 要旨 】 経皮内視鏡的胃瘻造設術 (PEG) は,長期にわたり経管栄養を必要とする症例に対し多くの利点をもつが,一方でその合併症も決してまれではない.PEGの合併症にはチューブ設置後,瘻孔壁が完成する前に発生する前期合併症と,瘻孔壁が完成した後に発生する後期合併症があり,本稿においてはPEG造設後長期経過中に発生する後期合併症について記述した.筆者の報告では後期合併症の頻度はPEG症例の約1割であり,栄養剤リーク,嘔吐,チューブ誤挿入,バンパー埋没症候群などを経験した.PEG後期合併症には偶発的に発生するものもあるが,不十分な管理により発生するものもあり,PEGに携わる医療従事者は十分な知識と経験をもって対応に当たる必要がある.

[ Summary ] While percutaneous endoscopic gastrostomy (PEG) has many advantages for those who require tube feeding for long-term nutritional support, its complications have been identified. There are mainly two types of complications related to PEG ; early complications that occur before the fistula is completed after the tube placement and late complications that occur thereafter. This report focuses on late complications. In our experience of 651 cases, late complications, such as leakage of nutrients, recurrent vomiting, inadequate insertion of exchanged tube, buried bumper syndrome, were found in approximately 10 % of patients with PEG. Some of the late complications occurred by accident, but others could have been avoided by appropriate management. Thus healthcare staffs engaged in PEG feeding are advised to obtain sufficient knowledge and experience.
