：PEG 近年来在国内发展较快，日益受到临床医师的重视。ESPEN 将 PEG 作为放疗患者肠内营养的首选途径， 并在 2006 年的肿瘤肠内营养指南中加以推荐。临床实践已证明，通过PEG 途径可以使晚期头颈部肿瘤的患者得到营养 治疗，停止并逆转体重丢失。PEJ 基于 PEG 发展而来，当患者存在胃或食管反流、幽门或十二指肠不全梗阻、胃或残胃有 排空障碍时，更适宜采用PEJ 途径。目前对于PEG 和 PEJ 的比较尚没有较高等级的RCT 能证实。PEJ 在临床上的使用与 PEG 相类似，PEJ 的选择应考虑患者是否存在 PEG 的禁忌证而适合使用 PEJ。

PEG was developed rapidly in recent years, attracted the attention of the clinicians. ESPEN regarded PEG as the preferred way of radiotherapy in patients with enteral nutrition, and it was recommend in the 2006 tumor enteral nutrition guidelines. Clinical practice had proved that advanced head and neck cancer patients could get nutritional treatment through PEG, stoping and reversing weight loss. PEJ was developed based on the PEG, PEJ was more suitable for patients with gastric/esophageal reflux, incomplete pyloric/duodenal obstruction and delayed gastric emptying. There was not high level of RCT comparing PEG with PEJ until now. The usage of PEJ was similar as PEG, the choice of PEJ should considered whether the patients was contraindicated for PEG.
