Abstract
BACKGROUND
The purpose of this study is to compare the safety and outcomes of percutaneous radiologic gastrostomy (PRG) in obese vs nonobese patients.
METHODS
This is an institutional review board-approved retrospective study of 109 patients (male:female, 68:41; mean age, 64.7 years; range, 21-94 years) who underwent PRG with or without gastropexy at a single academic medical center between 2015 and 2018. Body mass index (BMI) of ≥30 kg/m2 was defined as obese. Patient demographics, indications, technical success, intraoperative variables, and major/minor complications were analyzed. Major and minor complications occurring within 30 days of the procedure were recorded and categorized based on the Society of Interventional Radiology Quality Improvement guidelines.
RESULTS
Of 109 patients included in the study, 22.9% (n = 25) of patients were obese (average BMI, 34.6 kg/m2 ; range, 30-50). Overall technical success in the obese and nonobese groups was 100% each. In the obese vs nonobese group, major and minor complications were not significantly different. There were also no significant differences in procedure time, fluoroscopy time, or contrast volume. However, mean peak skin dose was significantly increased in the obese group vs nonobese group (190.3 ± 224.2 vs 59.1 ± 71.1 mGy; P < .0001).
CONCLUSION
PRG is a safe procedure in obese patients with similar technical success, major and minor complication rates, procedure time, fluoroscopy time, and contrast volume. However, PRG is associated with increased radiation dose with obese patients; therefore, optimal methods of radiation protection should be utilized.
