由於人口老化，於長期照護的病患中，合併有吞嚥困難而需使用鼻胃管灌食的病患相當普遍，進而可能導致反覆性吸入性肺炎和營養不良的問題。經皮內視鏡胃造口術（percutaneous endoscopic gastrostomy, PEG）是目前最有效且廣泛使用於各種病患的腸道營養方法。本文藉由說明PEG的定義、適應症、禁忌、併發症、優缺點及護理，並以臨床案例說明，協助讀者深入了解經皮內視鏡胃造口術之護理。

The dramatic increase in the elderly population in Taiwan has made dysphagia an increasingly prevalent problem in long-term care. While tube feeding is mandatory for patients unable to take food orally, this approach increases recurrent aspiration pneumonia and malnutrition risks. Percutaneous endoscopic gastrostomy (PEG) is currently the most effective and prevalent approach to enteral nutrition. This article introduces the definition, indications, contraindications, complications, advantages and disadvantages of PEG and its clinical nursing care protocols. The author hopes that this narrative description of a nurse’s experience providing appropriate nursing care to a PEG patient will help enhance reader understanding of PEG care.
