Percutaneous endoscopic gastrostomy (PEG) tube placement is the preferred method for long-term enteral feeding of patients who are unable to take food by mouth. Despite the widespread acceptance of the procedure, no large-scale study of the long-term outcomes of patients receiving PEG tubes has been reported. The objective of this study was to determine the survival of patients in whom PEG tubes are placed.
Retrospective cohort study using data obtained from two computerized databases.
Department of Veterans Affairs hospitals.
Seven thousand three hundred sixty-nine patients who received a PEG tube in fiscal years 1990 through 1992.
For the 7,369 patients, the mean age was 68.1 years and 98.6% were men. PEG tubes were most commonly places in patients with cerebrovascular disease (18.9%), other organic neurologic disease (28.6%), or head and neck cancer (15.7%). Although the complication rate of the procedure itself was low (4%), because of the severity of their underlying disease, 1,732 patients (23.5%) died during the hospitalization in which the PEG tube was placed. The median survival of the full cohort was 7.5 months.
This study documents the widespread placement of PEG tubes in severely ill patients, half of whom are in the terminal phase of their illness. Further study is needed to determine whether these patients benefit from PEG tube placement in terms of their quality of life and survival.
经皮内镜下胃造口术（PEG）置管是无法经口进食患者长期肠内营养的首选方法。尽管该手术已被广泛接受，但尚未有关于接受PEG管患者长期预后的大规模研究报道。本研究的目的是确定接受PEG管置管患者的生存率。
使用从两个计算机数据库获得的数据进行回顾性队列研究。
退伍军人事务部医院。
1990年至1992财年接受PEG管置管的7369例患者。
7369例患者的平均年龄为68.1岁，98.6%为男性。PEG管最常用于患有脑血管疾病（18.9%）、其他器质性神经疾病（28.6%）或头颈部癌（15.7%）的患者。尽管手术本身的并发症发生率较低（4%），但由于基础疾病的严重性，1732例患者（23.5%）在PEG管置管住院期间死亡。整个队列的中位生存期为7.5个月。
本研究记录了PEG管在重症患者中的广泛应用，其中一半患者处于疾病终末期。需要进一步研究以确定这些患者在生活质量和生存率方面是否从PEG管置管中获益。
