Frequency and predictors of small intestinal bacterial overgrowth in acute pancreatitis

Figure 1 Study protocol. SIBO: Small intestinal bacterial overgrowth.

Figure 2 Study flow chart. GHBT: Glucose hydrogen breath test; TB: Tuberculosis; IBD: Inflammatory bowel disease; CD: Crohn’s disease.

Figure 3 Frequency of small intestinal bacterial overgrowth in patients with acute pancreatitis vs those with healthy controls. ^aP < 0.001, categorical variables were compared with Fisher’s exact test (OR = 39.3; 95%CI: 4.8-324.6). SIBO: Small intestinal bacterial overgrowth; OR: Odds ratio; CI: Confidence interval.

Figure 4 Frequency of small intestinal bacterial overgrowth in patients with acute pancreatitis based on the severity of acute pancreatitis. The prevalence of SIBO increased with disease severity, being 11.1% (95%CI: 1.4%-34.7%) in mild acute pancreatitis, 75.0% (95%CI: 34.9%-96.8%) in moderate disease, and 100% (95%CI: 39.8%-100%) in severe disease (Fisher’s exact test, P < 0.001). SIBO: Small intestinal bacterial overgrowth; CI: Confidence interval.
