The changes in serum trypsin concentration have been measured in 47 subjects for up to 2 hours after a Lundh meal. In 18 healthy controls, mean fasting trypsin concentration was 285 +/- 125 ng/ml (mean +/- 2 SD). The maximum increase after the Lundh meal (the trypsin response ratio) was 6.7 +/- 7.5%. Six patients with chronic renal failure had elevated fasting serum trypsin concentrations (range 460-1100 ng/ml) but trypsin response ratios fell within the control range. Of five patients with relapsing pancreatitis, two had raised and three normal or low fasting trypsins. After stimulation two had elevated trypsin response ratios; one of the two had evidence of main duct obstruction. Eleven out of 12 patients with chronic pancreatitis (with or without insufficiency) had low fasting trypsin concentrations (range 0-120 ng/ml) Seven of the 12 also had raised trypsin response ratios. In six patients with cancer of the pancreas, fasting trypsin was low in three, normal in two, and raised in one. Both patients with a normal fasting level had a raised trypsin response ratio. The combination of a single estimation of fasting serum trypsin concentration followed by serial measurements after a Lundh meal provides a useful screening test for chronic pancreatic disease.

The deep duodenoscopy serves for the endoscopico-bioptic clarification of radiologically unclear findings distally from the bulb (niches, sockets, stenoses) and of the positional relations between diverticulum and papilla. As a rule, it is connected with an endoscopic retrograde cholangiopancreaticography (ERCP). The endoscopic retrograde pancreaticography is indicated in relapsing chronic pancreatitis for proving or excluding of changes needing operation which are taken into consideration as partial factors of the relapsing course as well as in suspicion to a local pancreatitis complication and carcinoma of the pancreas. The endoscopic retrograde cholangiography is a decisive aid for the differentiation of the cholostatic icterus. It improves the diagnostics of complaints after operative interventions at the system of the biliary ducts, facilitates the diagnosis of the papillary stenosis and is indicated in insufficient conventional contrasting the biliary ducts. The complications (pancreatitis, cholangitis, cystic infection) have become rare with increasing experience. Contraindications are the florid pancreatitis and cholangitis.

Stenosing odditis represents only 4.5 p. cent of all benign lesions of the extrahepatic bile ducts. Their diagnosis is made by peroperative radiomanometry, but clinically they are suggested by a past history and serious clinical signs. The pancreatic involvement is rarely macroscopic (10 p. cent of cases of which 5 p. cent are severe) and acute pancreatitis due to stricture of the sphincter without gall stones is exceptional. Associated biliary lesions are frequent; in 50 p. cent of cases, of lithiasis of the common bile duct or pancreatitis, in 66 p. cent of cases of residual odditis. The treatment is surgical. Sphincterotomy should be reserved for young subjects with a slightly dilated common bile duct, or when necessary to extract a gall stone from the lower end of the bile duct. Biliary by pass operations are all the more indicated when the patient is elderly or the common bile duct more dilated. Local complications are the most frequent and the most serious after sphincterotomy; the local complications of biliary by pass operations are usually very simple. The late results of biliary by-pass operations are better than those of sphincterotomy, which confirms that the pancreatic complications of odditis are rare or well tolerated. The presence of chronic pancreatitis in association is not an aggravating factor.

A 52 year old woman with a history of mild pancreatitis had a palpable mass in the upper abdomen. She died in an unexplained coma. The autopsy revealed an excessive hyperplasia of the exocrine pancreatic tissue resulting in the largest pancreas ever reported (254 gramm). This hyperplasia was accompanied by a chronic pancreatitis. In the central nervous system a Wernick's encephalopathy had developed; severe loss of neurons was stated in the thalamus; extensive degeneration was found in the upper vermis of the cerebellum. The discussion of this case includes the relationship between the diseases of the pancreas and neuropsychiatric and neuropathologic findings. It is assumed that the hyperplasia of the exocrine pancreatic tissue could only be an additional factor in the occurence of post alcoholic complications. This hyperplasia of the exocrine pancreatic tissue is considered to be a hamartom-like formation and it should therefore be distinguished from other pancreatic hyperplasia.

A 45-year-old man presented with what was thought to be a mass in the left upper lung and a pericardial friction rub. He was subsequently discovered to have a loculated pleural effusion and pericardial effusion associated with chronic pancreatitis. This is the first instance we were able to find of pancreatitis mimicking bronchogenic carcinoma with pericardial metastasis.

The five major diseases of the pancreas together make a significant contribution to morbidity and mortality among the people of the United States. These diseases are diabetes, cystic fibrosis, acute and chronic pancreatitis, and carcinoma of the exocrine pancreas. Four of these diseases can be modeled in laboratory animals by acute or chronic administration of chemical poisons or carcinogens. Human pancreatic diseases attributed to the effect of chemical agents including alcohol and drugs include many cases of chronic pancreatitis and some cases of acute pancreatitis. The cause is not known in many cases of human pancreatitis, including interstitial, acute, and chronic clinical forms. Epidemiologic studies suggest that the increasing incidence of carcinoma of the exocrine pancreas in the United States may reflect chemical carcinogenesis. On the basis of experimental observations, we know that pancreatic islet cells can be damaged directly by toxic chemicals, and that islet cell tumors can be chemically induced. Thus, there is adequate background data to conclude that several pancreatic diseases of obscure etiology may be due in part to hitherto unidentified toxic effects of chemical agents encountered in personal or general environments.

Role of ERCP in the diagnosis of inflammatory lesions of the pancreas was evaluated and following conclusions were obtained. 1) Following criteria were considered to be practical for clinical diagnosis of chronic pancreatitis by ERCP; a) More than moderate irregularity or rigidity of margin, dilatation, or irregularity in caliber of PDS, whether extensive or localized, or b) Cyst formation or c) Obstruction of PDS. These criteria permit to diagnose 100% of pancreatolithiasis, 82% of chronic pancreatitis without pancreatolithiasis and 64% of histologically diagnosed chronic pancreatitis but about 13% of "false positive results" must be taken into consideration. 2) ERCP plays an important role in detecting and locating localized or scattered lesions without noticable abnormalities in P-S test. It is also useful in deciding an indication for surgical intervention. However, it has limitations in detecting minimal to moderate pancreatitis. Some of these cases are often picked up by P-S test. 3) Combined approach with ERCP and P-S test is required for diagnosis of inflammatory lesions of the pancreas and either one is incomplete by itself.

The amylase/creatinine clearance ratio (Cam/Ccr ratio) was determined in 239 subjects. In 87 hospitalised patients without pancreatic disease (controls) the Cam/Ccr ratio was 3.02 +/- 0.69 (mean +/- ISD). The ratio was above the normal range in all patients with acute pancreatitis but was normal in those with chronic pancreatitis and carcinoma of the pancreas. In 18 patients with choledocholithiasis a raised ratio distinguished those with pancreatitis as assessed independently by the surgeon at laparotomy from those with a macroscopically normal pancreas. Raised Cam/Ccr ratios were also found in diabetics with ketoacidosis and in three patients with fulminant alcoholic liver disease. Though a positive correlation was found between the Cam/Ccr ratio and serum creatinine concentration, abnormally high ratios did not occur in 30 patients with chronic renal failure. A significant increase in Cam/Ccr ratios was produced in six healthy volunteers by intravenous injection of glucagon. However, it is unlikely that hyperglucagonaemia alone accounts for the increased Cam/Ccr ratio seen in acute pancreatitis, as no correlation was found between the clearance ratio and the plasma glucagon concentration in a series of patients. In two other patients in whom excess circulating pancreatic polypeptide was detected the Cam/Ccr ratio was normal. It is concluded that, in view of the sensitivity and relative specificity of finding an increased Cam/Ccr ratio in acute pancreatitis, its determination should be valuable clinically, especially in those cases of hyperamylasaemia where the cause is in doubt. The mechanism whereby the ratio is increased is unknown, and it is unlikely that either glucagon or pancreatic polypeptide is a major factor in its production.

In modern surgery, the pancrectomy is an operation indicated in a wide number of cases. Indications for such a procedure that were once limited to malignant lesions of the papilla of vater and the head of the pancreas now include chronic pancreatitis, some benign lesions of the duodenopancreatic area, and serious cases of acute necrotizing pancreatitis. Thanks to Modern surgical technique especially in anesthesia, reanimation, and postoperative care, the mortality rate in the partial pancrectomy is Recured to a rational number. Nonetheless, postoperative exiturs cannot be neglected. As a result it is necessary to consider strict indications for a pancrectomy. Only under such conditions can satisfactory therapeutic results be achieved.

Pathogenesis of pancreatitis was studied in experimental animals and essential fatty acid deficiency was condemned as an etiological factor, since it caused pathological changes in permeability of cell membrane of the pancreatic acinar cells. Favorable effects of intravenous fat emulsion was clearly demonstrated in treatment for acute and chronic pancreatitis.
