The aim of the work was to determine the frequency of the overgrowth bacterial syndrome (OBS) in the small intestine in patients with postcholecystectomical syndrome (PHES) justify the need for correction of the microflora and to assess the effectiveness of rifaximin at a dose of 800 and 1200 mg/day.
Materials and methods: With the help of the hydrogen breath test were examined 92 patients with PHES. 40 patients with OBS were treated with rifaximin, 20 of them received the drug at a dose of 800 mg and 20-1200 mg/day for 7 days. Effectiveness was determined by the dynamics of clinical symptoms and indicators of the hydrogen breath test.
Results and discussion: OBS was detected in 76% of the patients with PHES, which justifies the holding of antibiotic therapy. Lack of acceleration of peristalsis of small intestine as a cause of diarrhea was confirmed by the study of the electromotive activity of the small intestine, which revealed no differences from the norm. In some patients on therapy at a dose of rifaximin 800 mg/day uncropped pain and dyspeptic symptoms and was not accompanied by normalization of the hydrogen breath test. In the treatment of rifaximin at a dose of 1200 mg/day was showed normalization of the hydrogen breath test parameters in 90% of patients and relief of clinical symptoms in most patients.
Conclusion: Rifaximin at a dose of 1200 mg/day compared with a dose of 800 mg/day in patients with PHES associated with bacterial overgrowth in the small intestine, had a more pronounced clinical effect, as evidenced by positive dynamics in the form of relief of clinical symptoms and normalization of the hydrogen breath test.
