Percutaneous endoscopic gastrostomy (PEG) is a minimally invasive procedure with well-known efficacy and safety that is frequently used in patients who cannot be fed orally. In the literature, studies investigating long-term follow-up results in patients undergoing PEG are limited. In this study, we aimed to determine the long-term follow-up results and the factors affecting mortality in patients undergoing PEG.

Materials and Methods:

Two hundred and three patients who underwent PEG placement between January 2013 and June 2018 were evaluated retrospectively. The demographic characteristics of the patients, postoperative follow-up times, complications, PEG indications, laboratory parameters during the procedure were recorded from the patient files. During the follow-up period, the mortality and time of the patients were determined via the death notification system.


A total of 203 patients (101 male, 102 female) were included in the study. The median age of the patients was 77 years (18-96). The most frequent PEG placement indication was stroke with a frequency of 34%, followed by dementia (28.6%), malignancy (10.8%) and other (15.8%) reasons. The median follow-up period was 33.6 months (30.5-36.7) and the median survival was 22 months [95% confidence interval (CI): 22.8-30.5]. Mortality rates were 1.5% in the first month, 3% in 3 months, 12.3% in 1 year, 26.6 years in 2 years, 34.5% in 3 years and 44.3% in 5 years. There was no correlation between PEG indications and mortality, but there was a statistically significant correlation between hyponatremia and mortality (Odds ratio: 1.07, p=0.027, %95 CI).


There was no statistically significant relationship between PEG placement indications and mortality, but there was a statistically significant correlation between hyponatremia and mortality.
