简要总结

Most studies of bloating have focused on functional factors, while data on organic abdominal distention are rare, and studies that combine small intestine bacterial overgrowth and/or oral cecum transit time abnormalities are more urgent to explore. On this basis, patients with functional abdominal distension complicated with small intestine bacterial overgrowth were divided according to whether there was abnormal oral cecum transit time, and given the same treatment plan. The relief effect of abdominal distension, small intestine bacterial overgrowth turning negative and oral cecum transit time recovery were observed, so as to further clarify the cause of abdominal distension patients.

详细描述

Part 1 Clinical characteristics of small intestinal bacterial overgrowth in patients with abdominal distension of different etiologies The clinical characteristics of small intestine bacterial overgrowth and oral cecum transit time in patients with abdominal distention of different etiology (organic and functional) were studied to lay a foundation for further exploration of treatment of functional abdominal distention.

Part 2 Efficacy observation of functional abdominal distention combined with small intestine bacterial overgrowth To observe the effect of antibiotics on abdominal distension in patients with functional abdominal distension complicated with small intestine bacterial overgrowth, and observe the effect of rifaximin on small intestine bacterial overgrowth and oral cecum transit time, so as to provide new ideas for the diagnosis and treatment of abdominal distension patients.

研究组 & 干预措施

Sham Comparator(Normal oral cecum transit time)

Sham Comparator

Normal oral cecum transit time +functional abdominal distention +small intestinal bacterial overgrowth.Rifaximin (0.2g/ time, 4 times/day) was discontinued after 14 days of treatment.

干预措施: Rifaximin (Drug)

Experimental(Abnormal oral cecum transit time)

Experimental

Abnormal oral cecum transit time +functional abdominal distention +small intestinal bacterial overgrowth.Rifaximin (0.2g/ time, 4 times/day) was discontinued after 14 days of treatment.

干预措施: Rifaximin (Drug)

结局指标

主要结局

Part 1 Positive rate of small intestinal bacterial overgrowth

时间窗: 1 day

Positive rate of small intestinal bacterial overgrowth in organic and functional abdominal distension

Part 2 Negative conversion rate of small intestinal bacterial overgrowth and oral cecum transit time

时间窗: 2 weeks

1. Negative conversion rate of small intestinal bacterial overgrowth (%) =Number of small intestinal bacterial overgrowth negative after treatment/ Number of functional abdominal distention in Part 2\*100% 2. Negative conversion rate of oral cecum transit time (%) =Number of oral cecum transit time normal after treatment/ Number of experimental in Part 2\*100%

Part 1 Abnormal rate of oral cecum transit time

时间窗: 1 day

Abnormal rate of oral cecum transit time in organic and functional abdominal distension

Part 2 Effective rate of abdominal distension

时间窗: 2 weeks

Total effective rate (%) = Obvious effective rate (%) + Effective rate (%) 1. Obvious effect: the degree and frequency of abdominal distension score improved, or even completely disappeared, small intestinal bacterial overgrowth negative 2. Effective: the degree and frequency of abdominal distension score improved, small intestinal bacterial overgrowth positive 3. Ineffective: the degree and frequency of abdominal distension score did not improve
