An experimental method was developed for the production of acute hemorrhagic pancreatitis of uniform lethality in dogs, using the injection of a bile trypsin mixture into the major pancreatic duct. Fifteen of the 20 dogs treated with azathioprine survived as opposed to none of the ten treated conservatively.

Important experiences are reported from an analysis of 500 examinations. The ERCP gives eminent possibilities for the improvement of the pre- and postoperative diagnostics of the bile ducts, particularly in unclear cholestasis and in conditions after operations of the bile ducts. The ERCP is little suited for the early diagnosis of the carcinoma of the pancreas and for the ascertainment of the diagnosis in easy and moderate forms of chronic pancreatitis. Of particular value is the possibility to clear the causes of recidivations of pancreatitis as well as of complications of the severe chronic pancreatitis with regard to operative consequences.

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.

Twenty-eight consecutive patients with idiopathic pancreatitis were studied. Endoscopic retrograde cholangiopancreatography was diagnostic in 21 of 28, while an operation was diagnostic in four of the remaining seven patients. Fifteen of 25 patients had operable disease of the gallbladder, common bile duct, ampulla of Vater or pancreatic duct. Of ten patients who had an operation on the pancreas or biliary tract, or both, for painful attacks of pancreatitis, none had a recurrence in a seven month to three year follow-up study. Two patients had reconstruction of the pancreatic duct for chronic painless steatorrhea, one of whom had marked clinical improvement. Ten of 25 patients had normal biliary tracts with normal or minimally abnormal pancreatic ducts and were treated medically. Visualization of biliary and pancreatic ducts should be attempted by endoscopic retrograde cholangiopancreatography in patients with pancreatitis of unknown cause. Operable lesions were found in 15 of 25 patients, and the postoperative results were excellent.

In a personal series of 188 patients with pancreatic disease referred for endoscopic retrograde cholangiography (ERCP), one or more ducts were cannulated in 168 patients; of the 168 patients; of the 168 patients, 19 had carcinoma and 149 had chronic pancreatitis. Abnormalities were found in 71 of the 149 patients with pancreatitis, either in the pancreatic duct, the bile duct, or both ducts. The demonstration of these abnormalities was of critical importance in planning the management of these patients. Ducts were normal in 78 patients. No benefit could be expected from operating upon these patients. It is concluded that approximately one half of the patients with chronic pancreatitis will have demonstrable lesions amenable to operation, and one half will not. ERCP is essential in the investigation and management of patients suspected of having chronic pancreatitis.

In spite of extensive investigations, many aspects of the hemodynamic changes occurring in acute pancreatitis are understood poorly. A dog model was established in which continuous measurements of pancreatic arterial blood flow, cardiac output, and mean arterial blood pressure were made using electromagnetic flow probes and a pressure transducer, respectively. Pancreatitis was induced and the animals were monitored for 3 hours. In addition, control animals (group I) without pancreatitis also were done. All animals 50 ml of saline in the first hours. Three methods of therapy then were instituted in the dogs with pancreatitis and their effects were recorded. group I 6 dogs control animals no pancreatitis saline 50 ml/hr group II 10 dogs saline 50 ml/hr group III 6 dogs plasma 15 ml/kg over 45 min then saline 50 ml/hr group IV 10 dogs saline 50 ml and 1.5 ml/kg of dextran 40/hr These results confirm the observations made previously using a transillumination technique--that the pancreatic circulation rapidly reduces in acute pancreatitis. Administration of plasma produced a significant (P less than 0.05) but transient increase in the cardiac output and pancreatic blood flow; however, the blood pressure remained low. Dextran 40 minimally increased cardiac output, but it significantly improved the blood pressure and maintained the pancreatic blood flow. Low-dose, low-molecular weight dextran 40 appears to help to maintain pancreatic blood flow in acute pancreatitis. The possible mechanisms concerning the made of action of dextran 40 will be discussed.

We report the use of a new surgical procedure following pancreaticoduodenectomy in nine patients with chronic relapsing pancreatitis and its complications. The modification of the Whipple reconstruction following resection of the head of the pancreas consists in selective proximal vagotomy, transposition of a jejunal loop for bile duct, and pancreatic anastomosis. The longest follow up period has been 18 months. In agreement with reports on other procedures for resection of the head of pancreas, the patients who had been operated on suffered few symptoms. With one exception they had no pain at all; they all gained weight. The results of early follow-up examinations of the patients treated by to these procedures encourage continued use of duodenopancreatectomy.

In acute experiments on dogs with preliminarily induced pancreatitis the authors traced disturbances of the secretory reactions of the pancreas in response to adequate stimulation with the intestinal hormones. There was a reduction in the activity of complex intestinal hormones preparations obtained from the duodenal mucosa at the acute period of the disease in these dogs. In chronic experiments there was found an increase of acid production debit in the stomach and a shift in the duodenal contents reaction in the acid direction in pancreatitis. A conclusion was drawn on an important pathogenetic role played by the intestinal hormones in the mechanism of disturbances of the pancreatic exocrine secretion in pancreatitis.

In a group of 188 patients, 192 computed tomographic (CT) scans of the pancreas were done, and the diagnostic accuracy of CT determined relative to other modalities. CT was the most effective method of detecting neoplastic and inflammatory diseases. The full extent of the disease process, including involvement of the retroperitoneum and metastasis to the liver, was visualized with one examination. Calcification and cystic collections associated with pancreatitis were also clearly seen.

Five patients, each with a unique disease, illustrate some of the unusual subtleties of interpretation, the challenges of operative approach, the avoidance of pitfalls and the management of complications in local duodenal surgical procedures. A Brunner's gland polyp was resected reversing prior pancreatitis and cardiac alterations. A rare ampullary gangliocytic paraganglioma, hemorrhaging, was managed by duct isolations, resection and papilloplasty. A perforated malignant bleeding ulcer with eventual common bile duct obstruction and mimicking a benign ulcer, was approached with a variety of effective palliative procedures. A complicated duodenoileocolic cutaneous fistula in a patient with a background of granulomatous disease was resected. Finally, an obstructing duodenal stricture, attributable to progressive pancreatitis and presenting two years after bypass for jaundice, was managed by gastrojejunostomy and vagotomy, later converted to a Roux-en-Y preparation because of poor emptying and reflux bile gastritis.
