Serum trypsin levels have been estimated by radioimmunoassay in 26 healthy controls (248 +/- 94.9 micrograms/l; mean +/- s.d.), 12 patients with chronic renal failure (1100 +/- 584 micrograms/l), 34 with acute pancreatitis (1399 +/- 618 micrograms/l) and 23 with acute non-pancreatic abdominal conditions. Mean serum trypsin in acute pancreatitis and in chronic renal failure was significantly higher than in control group (P less than 0.001). Serum trypsin levels were well above the upper limit of normality in all patients with acute pancreatitis and in all but one with chronic renal failure. Serum trypsin was markedly raised in one patient with a traumatic haemoperitoneum and in one of the 11 with peptic ulcer perforation, and moderately raised in 3 of the 6 with acute cholecystitis. Determination of serum trypsin seems to be a specific test for acute pancreatitis, provided renal failure has been excluded. However, the authors suggest it should be prospectively measured in a larger series of acute non-pancreatic abdominal conditions.

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.
