Abstract
Background/Objectives: Percutaneous endoscopic gastrostomy (PEG) is recommended for long-term enteral nutrition in dysphagic patients. This study aims to characterize conditions motivating PEG, assess nutritional status on the gastrostomy day, evaluate survival and search for survival predictors. Methods: Retrospective study of adult patients who underwent PEG in a tertiary hospital from 2001 to 2023. Data collected included demographics, underlying disorders, nutritional status (anthropometry/laboratory evaluation) on the day of PEG and survival recorded until death or December 2023. Multivariable analysis was performed with Cox regression to search for survival predictors. Results: A total of 1415 patients were included (61.8% males, mean age 66.9 years); 66.4% presented a neurological disorder and 31.3% head and neck or esophageal cancers (HNC/EC). The mean BMI was 20.9 kg/m(2), with 49.8% underweight. Albumin, transferrin and total cholesterol were low at 43.2%, 62.2% and 50%, respectively. Median overall survival was 11.1 months; 14.1% of deaths occurred within 4 weeks. HNC/EC patients showed lower survival than neurological patients. Potentially regressive neurological conditions presented longer survival than progressive ones. Predictors of increased survival included female gender, younger age, higher albumin and higher BMI. The protective effect of BMI and albumin was more pronounced in males than in females. Conclusions: Neurological disorders were the most frequent underlying conditions. Nearly half of the patients displayed malnutrition before PEG feeding. Although PEG-fed patients displayed a considerable median survival time, some died early without benefit from PEG. Patients with potentially regressive neurological conditions presented better outcomes. Female gender, younger age, higher albumin and higher BMI were associated with longer survival.
