Abstract
Biliary sludge is a collection of mucus, calcium bicarbonate and cholesterol crystals that is usually recognized by characteristic echoes on ultrasonography. Sludge was found in conditions with functional or organic disturbance of gallbladder emptying as atonic gallbladder in the fasting state. Some recent papers have been reported that there is a high frequency of gallbladder disease in patients on long term parenteral nutrition. The enhanced risk of gallbladder disease in these patients has been ascribed to bowel rest and gallbladder stasis. The influence of fasting on the gallbladder and hepatic bile composition in human has been studied for a period of 10 - 20 hours where gallbladder bile becomes signific¬antly supersaturated after 15 hours but cholesterol saturation falls after 20 hours. The aim of our study was to perform a prospective study using sequential ultrasound examination to assess the prevalence of gallbladder sludge formation and lithiasis in Ramadan fasting month in non-biliary non-pancreatic dyspeptic patients with schistosomal hepatosplenic disease.
