BACKGROUND: The relationship between body weight and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) is unclear.
OBJECTIVES: This study aimed to investigate the impact of obesity and morbid obesity on mortality and ERCP-related complications in patients who underwent ERCP.
METHODS: We conducted a US population-based retrospective cohort study using the Nationwide Readmissions Databases (2013-2014). A total of 159,264 eligible patients who underwent ERCP were identified, of which 137,158 (86.12%) were normal weight, 12,522 (7.86%) were obese, and 9584 (6.02%) were morbidly obese. The primary outcome was in-hospital mortality. The secondary outcomes were the length of stay, total cost, and ERCP-related complications. Multivariate analysis and propensity score (PS) matching analysis were performed. The analysis was repeated in a restricted cohort to eliminate confounders.
RESULTS: Patients with morbid obesity, as compared to normal-weight patients, were associated with a significantly higher in-hospital mortality (hazard ratio [HR]: 5.54; 95% confidence interval [CI]: 1.23-25.04). Obese patients were not associated with significantly different mortality comparing to normal weight (HR: 1.00; 95% CI: 0.14-7.12). Patients with morbid obesity were also found to have an increased length of hospital stay and total cost. The rate of ERCP-related complications was comparable among the three groups except for a higher cholecystitis rate after ERCP in obese patients.
CONCLUSIONS: Morbid obesity but not obesity was associated with increased mortality, length of stay, and total cost in patients undergoing ERCP.
