title: Altered small bowel motility in patients with liver cirrhosis depends on severity of liver disease.
abstract: Abnormal small bowel motility has been described in patients with liver cirrhosis but the mechanisms involved are unknown. The aim was to investigate a possible relationship between the severity of liver failure and the intensity of small intestinal abnormalities. Motility was studied during fasting, by means of perfused catheters and external transducers, on 33 cirrhotics with different etiologies; 8 were at Child-Pugh stage A, 12 stage B, and 13 stage C. Both abnormalities of MMC and increased clustered activity were recorded. Absence of cycling activity was most frequently observed in Child-Pugh stage C patients compared to Child-Pugh stage A cirrhotics. A significant increase in clustered contractions from 4.7 +/- 0.4/hr in stage A patients to 11.3 +/- 1.1 in stage C was recorded. The frequency and amplitude of contractions was also increased from Child-Pugh stage A to stage C. Our findings might be related to a delayed transit time observed in these patients and a higher prevalence of bacterial overgrowth in cirrhotics with more advanced liver disease.
