To assess the possibility of common bile duct distensibility after cholecystectomy, we made a retrospective study of patients who had ultrasonography and endoscopic retrograde cholangiopancreatography (ERCP). The study comprised 52 patients without extrahepatic biliary obstruction; 19 had had cholecystectomy, 18 of whom complained of biliary colic similar to that they had had originally. The other 33 patients had intact, well visualized gallbladders; 15 of these patients had pain in the right upper quadrant or epigastrium, but none had chronic pancreatitis. The average diameter of the common bile duct at its widest point by ultrasonography was 4.8 mm (range, 4.0 to 9.0 mm) in the 33 patients with intact gallbladders, and 5.7 mm (range, 4.0 to 8.0 mm) in the 19 patients who had had cholecystectomy. The diameter by ERCP was 4.4 mm (range, 2.9 to 6.3 mm) in the patients with intact gallbladders, and 11.17 mm (range, 6.9 to 14.7 mm) in the patients who had had cholecystectomy. In each patient who had had cholecystectomy the diameter as measured by ERCP was larger than it appeared by ultrasonography. The results suggest that the common bile duct is distensible, and that this distensibility may be related to the postcholecystectomy syndrome.

Between October 1987 and July 1990 a prospective, nonrandomized, preliminary study was carried out to assess the efficacy of Sandostatin in treating complex pancreatic and gastrointestinal disorders. The study group consisted of 18 women and 12 men, ranging in age from 23 to 80 years (mean 50 years), in whom conventional medical or surgical therapy, or both, had failed. Nineteen patients had pancreatic disease (5 had chronic pancreatitis, 8 acute necrotizing pancreatitis and 6 pancreatic fistula). Thirteen patients had disorders of the small intestine (7 had enterocutaneous fistula and 6 diarrhea-associated short-gut syndrome). Sandostatin was found to be effective in the closure of pancreatic (five of six cases) and enterocutaneous fistulas (five of seven cases), of benefit in controlling the pain associated with chronic pancreatitis (three of five cases) and of some use in achieving short-term control of intractable diarrhea in patients with short-gut syndrome (five of six cases). It was of particular benefit in the management of acute necrotizing pancreatitis. The standard principles of surgical management must be adhered to when using Sandostatin to treat patients with these disorders. Sandostatin can not correct underlying problems such as pancreatic-duct obstruction, malignant disease or unresolved sepsis. These preliminary results justify more widespread use of Sandostatin as part of a prospective randomized and controlled multicentre trial.

This chapter focuses on studies dealing with the feedback mechanism of pancreatic exocrine secretion in animal and man. Clear evidence is presented that this feedback mechanism is working in the rat and the pig and that this feedback is mediated in the rat by the gastrointestinal hormones pancreozymin (enzyme secretion) and secretin (volume and bicarbonate secretion). Two novel peptides have been described--the 'CCK-releasing peptide' originating from the small intestinal mucosa, and the 'monitor peptide' cosecreted together with the enzymes in the pancreatic juice--to account for the stimulation of pancreatic enzyme secretion by the release of CCK. A similar feedback regulation of pancreatic secretion is working in man. It remains as yet controversial whether the feedback in humans is regulated via hormonal or neural pathways. It is also a matter of debate whether this feedback regulation of pancreatic enzyme secretion could be utilized for therapeutic aims in the treatment of pain in patients with chronic pancreatitis.

Truncal subdiaphragmatic vagotomy with pyloroplasty was used in 28 patients with chronic relapsing pancreatitis, 19 of them were inclined to alcohol abuse. In 27 patients followed-up during 3 years, 18 were delivered from pain attacks resulting from chronic pancreatitis, the attacks became rarer and less intense in 4 patients, 3 patients had single attacks of pancreatic colic. In 2 patients the results of treatment were assessed as unsatisfactory due to often admission to the hospital for pain attacks. They were not found to have increased excretory and endocrine insufficiency of the pancreas in this period, but had mental disorders.

Chronic calcific pancreatitis (CCP) is the most clear-cut form of chronic pancreatitis. Till date, the common treatment of CCP has been directed toward discontinuation of alcohol consumption if the disease is associated closely with alcohol abuse, relief of pain, enzyme replacement, and the management of some complications like diabetes mellitus, cyst or abscess of the pancreas, malnutrition etc. In 1979, the research group for chronic pancreatitis in Japan proposed the therapeutic policy for this disease as illustrated in Fig. 1. A plausible new treatment is the dissolution of protein precipitates or calcified stones in pancreatic ducts by oral or intravenous administration of drugs.

The observation that drainage of the MPD in selected cases of severe chronic pancreatitis has a radical benefit on pain reduction supports the hypothesis that pain is mainly due to obstruction of the MPD. Further follow-up study is needed to assess whether endoscopic management can prevent progression of the disease and especially postpone the onset of diabetes and steatorrhea. The iterative character of the endoscopic management is at least an advantage when compared with surgery, which, in principle, might be considered definitive in only one operation. The present excellent results of non-surgical management of chronic pancreatitis suggest that these new procedures will find a prominent role similar to that already achieved for biliary tract procedures. Therapeutic endoscopy of the pancreas and chronic pancreatitis has focused on the 'stone and stricture' nature of the disease, and techniques have developed accordingly.

"Stenosing papillitis" is a descriptive term for an anatomic deformity of the papilla of Vater that is characterized by narrowing of the lower end of the bile duct and the proximal end of the duct of Wirsung. The defect is secondary to inflammation and fibrosis from the chronic passage of gallstones, episodes of acute pancreatitis, chronic pancreatitis, sclerosing cholangitis, peptic ulcer disease, and cholesterolosis. Patients with papillary stenosis from gallstones may present with episodes of severe upper-abdominal pain several years after cholecystectomy. The pain is often incapacitating, and patients are often addicted to narcotic analgesics. The work-up includes abdominal ultrasonography and CT scanning and endoscopic retrograde cholangiopancreatography even though the findings usually are normal. Liver and pancreatic enzymes are not frequently elevated with the painful episodes. Transendoscopic manometry may reveal elevated pressures within the papillary portion of the distal bile duct. Some patients are relieved of their pain by transduodenal sphincteroplasty and transampullary septectomy, thereby ablating the sphincter of Oddi around the bile and pancreatic ducts and enlarging their openings.

Primary sclerosing cholangitis is a rare disease of unknown etiology. Sclerosis of the bile ducts may actually be the final result of multiple factors such as autoimmune, bacterial, congenital, drug, or viral injury. The most commonly associated diseases are ulcerative colitis and chronic pancreatitis. Except in the earliest stages of the disease, liver histologic findings are not specific. Most patients present with jaundice, pain, and pruritus, although an increasing number of asymptomatic patients with inflammatory bowel disease and abnormal liver function are being identified. Cholangiography is key to the diagnosis and is usually pathognomonic except in the unusual case where primary sclerosing cholangitis is confused with cholangiocarcinoma. Many forms of medical therapy have been tried, including antibiotics, azathioprine, cholestyramine, colchicine, cyclosporine, D-penicillamine, steroids, and ursodeoxycholic acid. To date, none of these medications has been proved to alter the course of this disease. Recent reports of ursodeoxycholic acid trials have been encouraging, but long-term results of ongoing randomized trials have yet to be published. In recent years, balloon dilatation of biliary strictures has been accomplished via endoscopic and percutaneous transhepatic approaches. However, in patients with primary sclerosing cholangitis, these nonoperative manipulations must be done repeatedly, may entail multiple general anesthetics, and are difficult to perform. We believe that a direct surgical approach to the biliary tree with long-term transhepatic stenting is indicated in selected patients with severe hilar or extrahepatic stricturing, persistent jaundice or recurrent cholangitis, and no evidence of cirrhosis. Hepatic transplantation should be reserved for patients with primary sclerosing cholangitis who have well-established cirrhosis and have not responded to other therapeutic measures.

Pancreatic tissue fluid pressure was measured in 10 patients undergoing drainage operations for painful chronic pancreatitis. The pressure was measured by the needle technique in the three anatomic regions of the pancreas before and at different stages of the drainage procedure, and the results were compared with preoperative endoscopic retrograde cholangiopancreatography (ERCP) morphology. The preoperatively elevated pressure decreased in all patients but one, to normal or slightly elevated values. The median pressure decrease was 50% (range, 0-90%; p = 0.01). The drainage anastomosis (a pancreaticogastrostomy) was made in the body of the pancreas, but the pressure decrease in this region was not significantly different from that in the head and tail. The pressure decrease was independent of findings during ERCP (stone, total duct obstruction, or major ductal stenosis). In conclusion, the results showed a decrease in pancreatic tissue fluid pressure during drainage operations for pain in chronic pancreatitis. Regional pressure decrease were apparently unrelated to ERCP findings.

The relation between pancreatic tissue fluid pressure and pain, morphology, and function was studied in a cross-sectional investigation. Pressure measurements were performed by percutaneous fine-needle puncture. Thirty-nine patients with chronic pancreatitis were included, 25 with pain and 14 without pain. The pressure was higher in patients with pain than in patients without pain (p = 0.000001), and this was significantly related to a pain score from a visual analogue scale (p less than 0.001). Patients with pancreatic pseudocysts had both higher pressure and higher pain score than patients without (p = 0.004 and p = 0.0003, respectively). The pressure was significantly related (inversely) to pancreatic duct diameter only in the group of 19 patients with earlier pancreatic surgery (R = -0.57, p = 0.02). The pressure was not related to functional factors or the presence of pancreatic calcifications. In conclusion, pancreatic tissue fluid pressure is a valuable indicator of pain in chronic pancreatitis.
