Ability of lactulose breath test results to accurately identify colorectal polyps through the measurement of small intestine bacterial overgrowth

Figure 1 Rate of intestinal barrier function damage in 227 small intestine bacteria overgrowth patients. ^aThe rate of intestinal barrier function damage (IBFD) by 3 blood assays altogether was marginally higher in polyp group than that in non-polyp group, but no significance, P = 0.13. ^bIt was significantly different between polyp group and non-polyp group when IBFD defined by lipopolysaccharide alone, P < 0.05. SIBO: Small intestine bacteria overgrowth; DAO: Diamine oxidase; LPS: Lipopolysaccharide.
