Increased gallbladder trypsin in acute cholecystitis indicates functional disorder in the sphincter of oddi and could make EPT a logical procedure.
Clinical and surgical observations confirm that acute cholecystitis (ACh) and acute biliary pancreatitis can coexist and that differentiation may be difficult even at surgery. Synchronous appearance of ACh and acute biliary pancreatitis suggests a similar etiology. Endoscopic sphincterotomy, with relief of the common channel outlet obstruction, has become the established therapeutical modality that improves the outcome in acute biliary pancreatitis. Patients suffering from ACh could be treated in a similar manner to prevent reflux of pancreatic juice into the common bile duct and the gallbladder with the intention to improve the clinical course. The present study investigated the presence and amount of pancreatic trypsin in the gallbladder bile in 73 patients operated on for gallstone disease with ACh and in controls. The average gallbladder bile trypsin level in the "edematous cholecystitis" group ranged between 0.525 and 4500 ng/mL, significantly exceeding that of controls, 0.5-53 ng/mL (P < 0.0001). The average gallbladder bile trypsin level in the "gangrenous cholecystitis" group, 0.1-71.5 ng/mL, was within the range of controls (n.s.), most likely to be explained as a consequence of consumption of trypsin due to the fulminant development of the disease. Further controlled studies are mandatory before it would be acceptable to recommend endoscopic sphincterotomy as a valuable choice in the initial/early management of patients suffering from ACh. Such a study is underway to assess the possible role of obstruction at, or other disorders of, the sphincter of Oddi with consequent pancreatic juice reflux into the gallbladder as a possible initial cause of ACh.
