Abstract
Background and Aims
Clostridium difficile infection (CDI) is major health care concern with reports linking it to obesity. Our aim was to investigate the little known impact of the two most common bariatric surgeries, Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG), on risk of CDI admissions.
Methods
This is a retrospective cohort study using the 2013 Nationwide Readmission Database. We examined inpatient CDI rates within 120 days after RYGB (n = 40,059) and VSG (n = 45,394). In a time to event analysis we also evaluated inpatient CDI rates up to 11 months post-surgery. We chose morbidly obese patients that underwent non-emergent ventral hernia repair (VHR) as additional surgical controls (n = 9673).
Result
CDI rates were higher after RYGB than VSG in the first 30 days (odds ratio [OR] = 2.10; 95% confidence interval [CI], 1.05–4.20) with a similar but nonsignificant trend within 31–120 days. CDI rates were also higher after RYGB compared to VHR controls within 31–120 days after surgery (OR = 3.22, 95%CI: 1.31, 7.88, p = 0.01). In a time to event analysis with up to 11 months follow up, RYGB led to higher CDI compared to VSG (hazard ratio [HR] = 1.87; 95% CI, 1.12–3.13) with a trend towards higher CDI compared to VHR (HR = 1.95; 95% CI, 0.94–4.06). Similar CDI rates occurred after VSG vs VHR.
Conclusions
RYGB may increase the risk of CDI hospitalization when compared to VSG and VHR controls. This data suggest VSG may be a better bariatric choice when post-surgical CDI risk is a concern.
