Background
Early intra-abdominal infections (IAI) compromise short-term outcomes in bariatric surgery. The timely detection of IAI is challenging but essential to prevent major sequelae of such complications. C-reactive protein (CRP) is a reliable marker for detecting IAI after colorectal surgery. In bariatric surgery, data on CRP as a marker for IAI are limited, particularly for postoperative day one (POD1).
Objective
The objective of this study was to assess CRP on POD1 as a predictor for early IAI (within 7 days following surgery) in patients after laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (LRYGB).
Methods
Patients with bariatric surgery between 08/2010 and 06/2017 were included. The predictive capacity of CRP for early IAI was determined using a receiver operating characteristics (ROC) analysis.
Results
In 523 patients (68.5% female, LSG = 358, LRYGB = 165), 16 (3%) early IAI were observed. ROC analysis revealed a significant predictive capacity of POD1 CRP for early IAI, with a sensitivity and a specificity of 81.2 and 94.3%, respectively, at a CRP cut-off value of 70 mg/L. In patients with confirmed early IAI, 81.3% had a CRP level ≥ 70 mg/L (LSG 85.7%, LRYGB 77.8%). The negative predictive value for a CRP level < 70 mg/L was 99.4% overall and was 100 and 98% for LSG and LRYGB, respectively.
Conclusion
In patients with a CRP level < 70 mg/L on POD1, early IAI can be excluded with high accuracy in bariatric patients. Thus, early postoperative CRP may be used to assess the risk of early IAI in enhanced recovery programs.
