With an aging population, the number of patients with difficulty swallowing due to medical conditions is gradually increasing. In such cases, enteral nutrition is administered through a temporary nasogastric tube. Long-term use of a nasogastric tube leads to various complications and a decreased quality of life. Percutaneous endoscopic gastrostomy (PEG) is the percutaneous placement of a tube into the stomach, aided endoscopically, which may be an alternative to a nasogastric tube when enteral nutritional is required for 4 weeks or more. This paper is the first Korean clinical guideline for PEG. It was developed jointly by the Korean College of Helicobacter and Upper Gastrointestinal Research and led by the Korean Society of Gastrointestinal Endoscopy. These guidelines aimed to provide physicians, including endoscopists, with the indications, use of prophylactic antibiotics, timing of enteric nutrition, tube placement methods, complications, replacement, and tubes removal for PEG based on the currently available clinical evidence.

经皮内窥镜胃造口术临床实践指南。

随着人口老龄化，因医疗条件导致吞咽困难的患者逐渐增多。在这种情况下，通过临时鼻胃管进行肠内营养。长期使用鼻胃管会导致各种并发症和生活质量下降。经皮内窥镜胃造口术 (PEG) 是在内窥镜辅助下经皮将管置入胃中，当需要肠内营养 4 周或更长时间时，这可以替代鼻胃管。该论文是韩国第一个 PEG 临床指南。它由韩国螺杆菌和上消化道研究学院联合开发，并由韩国胃肠内窥镜学会领导。这些指南旨在根据现有的临床证据，为包括内窥镜医师在内的医生提供 PEG 的适应症、预防性抗生素的使用、肠内营养的时机、置管方法、并发症、更换和拔管等信息。
