As altered gastrointestinal motility could be involved in the pathogenesis of small intestinal bacterial overgrowth observed in liver cirrhosis, we investigated mouth to caecum transit time (MCTT) and solid meal gastric emptying (SMGE) in patients with cirrhosis. MCTT was estimated in 20 cirrhotics and 12 healthy controls using lactulose hydrogen breath test. SMGE was measured in 12 patients with cirrhosis and 27 controls by means of 99-m Tc-sulphur colloid labelling egg albumin and gamma scintigraphy. T1/2 and percentage of marker remaining in stomach (MRS) at 60, 90, and 120 min were calculated. MCTT was prolonged in patients with cirrhosis (111 +/- 7 min) compared to controls (83 +/- 6 min; p < 0.02). No significant differences were demonstrated in SMGE t1/2 between controls (84 +/- 5 min) and cirrhotics (91 +/- 6 min). Also, MRS was similar in patients with cirrhosis and healthy controls at 60, 90 and 120 min. We conclude that MCTT is prolonged in patients with cirrhosis. In addition, our data suggest that pyloruscaecum component plays the main role in delaying orocaecal transit time in cirrhosis.
由于胃肠动力改变可能参与肝硬化患者小肠细菌过度生长的发病机制,我们研究了肝硬化患者的口至盲肠转运时间(MCTT)和固体餐胃排空(SMGE)情况。使用乳果糖氢呼气试验对20例肝硬化患者和12例健康对照者进行MCTT评估。通过99m锝-硫胶体标记蛋清蛋白和γ闪烁扫描法对12例肝硬化患者和27例对照者进行SMGE测量。计算60、90和120分钟时的T1/2以及胃内标记物残留百分比(MRS)。与对照者(83±6分钟;p<0.02)相比,肝硬化患者的MCTT延长(111±7分钟)。对照者(84±5分钟)和肝硬化患者(91±6分钟)的SMGE t1/2无显著差异。此外,肝硬化患者和健康对照者在60、90和120分钟时的MRS相似。我们得出结论,肝硬化患者的MCTT延长。此外,我们的数据表明,幽门-盲肠部分在肝硬化患者口-盲肠转运时间延迟中起主要作用。
