Background/Aims: Impaired gallbladder motility has been suggested as a contributor to increased incidence of gallstones in patients with liver cirrhosis. The purpose of this study was to determine gallbladder function and its relation with autonomic neuropathy in liver cirrhosis. Materials and Methods: Gallbladder function was measured using ultrasonography in 48 patients with liver cirrhosis and in 31 controls. Autonomic neuropathy tests were applied in patients with liver cirrhosis. Patients with liver cirrhosis were analyzed in subgroups according to the severity of disease using the Child-Pugh classification. Results: Fasting gallbladder volume was 16.2 mL (range: 2.1 mL-71.9 mL) in patients and 17.6 mL (range: 4.9 mL-76.6 mL) in controls. There were no differences in fasting gallbladder volume among the study groups (p>0.05). Gallbladder ejection fraction was significantly higher in patients compared with controls (84% vs. 65%) (p<0.001). No correlation was found between gallbladder ejection fraction and autonomic neuropathy (p>0.05). Conclusion: Our results indicate that liver cirrhosis does not impair gallbladder emptying, and that there is no association between gallbladder motility and autonomic neuropathy. Further investigations are required to explain increased gallbladder motility in liver cirrhosis.

This paper reviews the progress made in understanding the mechanical behaviour of the biliary system. Gallstones and diseases of the biliary tract affect more than 10% of the adult population. The complications of gallstones, i.e. acute pancreatitis and obstructive jandice, can be lethal, and patients with acalculous gallbladder pain often pose diagnostic difficulties and undergo repeated ultrasound scans and oral cholecystograms. Moreover, surgery to remove the gallbladder in these patients, in an attempt to relieve the symptoms, gives variable results. Extensive research has been carried out to understand the physiological and pathological functions of the biliary system, but the mechanism of the pathogenesis of gallstones and pain production still remain poorly understood. It is believed that the mechanical factors play an essential role in the mechanisms of the gallstone formation and biliary diseases. However, despite the extensive literature in clinical studies, only limited work has been carried out to study the biliary system from the mechanical point of view. In this paper, we discuss the state of art knowledge of the fluid dynamics of bile flow in the biliary tract, the solid mechanics of the gallbladder and bile ducts, recent mathematical and numerical modelling of the system, and finally the future challenges in the area.

“…The gallbladder and gastric antral measurements were taken every five minutes for forty minutes while the gastric antral measurements were obtained at fifth, tenth and the fifteen minutes. The gallbladder volumes were assessed by the ellipsoid method [10]. The gastric antral area was assessed using a standard formula [9] Gallbladder contraction index was calculated as the percentage change in volume at each period using the fasting volume as baseline volume.…”
