Mechanisms underlying the roles of nervous and humoral factors in the pathogenesis of gallstones

Gallstone disease is a common disorder with an incidence rate of about 10%. Recent research has revealed that nervous and humoral factors are involved in the pathogenesis of gallstone disease. This article focuses on the mechanisms underlying the roles of parasympathetic nerve, sympathetic nerve, non-adrenergic non-cholinergic nerve, cholecystokinin, gastrin, bombesin, gastrin-releasing peptide, motilin, vasoactive intestinal polypeptide, somatostatin, pancreatic polypeptide, substance P, secretin, neurotensin, opioid peptide, nitric oxide, estrogen, thyroxine, and leptin in the pathogenesis of gallstones.

Biliary dyskinesia

Functional disorders of the biliary tract include gallbladder dyskinesia (GBD) and sphincter of Oddi dysfunction (SOD). The diagnosis of GBD is made if the gallbladder ejection fraction is less than 35% to 40% using cholecystokinin cholescintigraphy. Despite slightly inferior outcomes compared with calculous disease, patients who have GBD should be treated with cholecystectomy. SOD is most often noted in the postcholecystectomy patient and symptoms can be biliary or pancreatic in nature. The gold standard for diagnosis remains manometry, with basal biliary or pancreatic sphincter pressures measuring greater than 40 mm Hg. Patients who have increased pressures may benefit from endoscopic sphincterotomy.
