Outcomes following percutaneous endoscopic gastrostomy versus fluoroscopic procedures in the Medicare population

In the United States, few high-quality manuscripts have directly compared the complication profiles of percutaneous endoscopic versus fluoroscopic gastrostomy. Thus, it is our goal to compare these 2 common procedures to better understand their efficacy and complication profiles.

A retrospective analysis of patient records from Medicare parts A/B from 2007 to 2012 was used to identify percutaneous fluoroscopic gastrostomy and percutaneous endoscopic gastrostomy procedures. Patient demographics were stratified by age, sex, comorbidities, and complications.

A total of 258,641 patients were found to have either percutaneous fluoroscopic gastrostomy (26,477, 10.2%) or percutaneous endoscopic gastrostomy (232,164, 89.8%). Percutaneous fluoroscopic gastrostomy experienced greater rates for all complications queried. Multivariate analysis revealed that the percutaneous fluoroscopic gastrostomy cohort had statistically significant increased odds for short-term complications, such as ileus (odds ratio 1.4, 95% confidence interval 1.22-1.54), mechanical (odds ratio 2.4, 95% confidence interval 2.28-2.58), wound infection (odds ratio 1.4, 95% confidence interval 1.24-1.52), persistent fistula after tube removal (odds ratio 1.9, 95% confidence interval 1.78-2.12), and other complications (odds ratio 2.2, 95% confidence interval 2.03-2.37), and long-term complications, including abdominal wall pain (odds ratio 1.4, 95% confidence interval 1.33-1.44), wound infection (odds ratio 1.1, 95% confidence interval 1.01-1.15), and persistent fistula after tube removal (odds ratio 1.8, 95% confidence interval 1.72-1.87).

Gastrostomy tubes are more frequently being placed via percutaneous endoscopic and fluoroscopic methods. This study suggests that those undergoing fluoroscopic placement have higher odds of developing short- and long-term postoperative complications.
