  • Title: The role of the gallbladder in the pathogenesis of cholesterol gallstones.
    Author: LaMorte WW, Schoetz DJ, Birkett DH, Williams LF.
    Journal: Gastroenterology; 1979 Sep; 77(3):580-92. PubMed ID: 456853.
    Abstract:
    During the past century, a variety of explanations have been proposed to explain the pathogenesis of cholesterol gallstones. Early attempts to account for the phenomenon of cholelithiasis focused on events in the gallbladder and stressed mucosal inflammatory changes, gallbladder stasis, stratification of bile, and absorption of bile salts from a damaged mucosa. The advent of the concept of "lithogenic bile" redirected attention to the liver and led to the proposal that an enzyme-mediated genetic and/or metabolic defect is the initiator of cholesterol cholelithiasis. While recognizing that the pathogenesis of gallstones is probably multifactorial, alterations in gallbladder and biliary ductal motor function constitute a plausible, but as yet unexplored, mechanism for alterations in enterohepatic circulation dynamics and subsequent cholesterol cholelithiasis. Gallbladder motor function is a complex phenomenon influenced by dynamic compliance, autonomic pharmacology, hormonal responses, and sphincter dynamics. Attempts to describe these aspects of biliary physiology may characterize the next phase in our understanding of the pathogenesis of cholesterol cholelithiasis.
