Acute biliary tract disease complicated intrauterine pregnancy in 26 patients seen during a 5 year period. Biliary symptoms were distinct and occurred during the first trimester in 7 patients, the second trimester in 5 patients, the third trimester in 12 patients, and in two early postpartum patients. Nine patients had marked hyperamylasemia which resolved with medical management, and no severe cases of pancreatitis occurred. Ultrasonography was used to confirm the presence of gallstones in 18 patients and demonstrated dilated intrahepatic ducts in one of two patients with surgically proved choledocholithiasis. Nineteen patients had cholecystectomy and cholangiography, and 4 had common bile duct explorations. Only two of seven patients who presented in the first trimester had term pregnancy. Diagnosis of cholelithiasis in pregnancy by ultrasonography is accurate and reliable. The risk to the fetus of radionuclide scanning and conventional radiography is not justified. Secondary hyperamylasemia is common but responds to conservative therapy. Operation may be delayed until delivery in most patients, with urgent exploration reserved for uncertainty in diagnosis, choledocholithiasis, or acute cholecystitis that does not resolve with medical measures.

Acute pancreatitis in North-East Scotland from January 1983 to December 1985 was examined. The criteria for diagnosis were a serum amylase greater than 1000 units/l with a consistent clinical presentation, or acute pancreatitis confirmed at laparotomy or post mortem. All serum amylase assays were performed in one regional laboratory. The commonly used diagnostic coding search for pancreatitis yielded only half the cases found. We identified 378 episodes of acute pancreatitis (196 males and 182 females). The mean annual incidence for first attacks of acute pancreatitis was 242 per million of the population. The commonest aetiology was biliary tract disease (30 per cent of males and 53 per cent of females). Alcohol related pancreatitis occurred in 26.5 per cent of males but only 3 per cent of females. Complications included 26 pseudocysts, 11 pancreatic abscesses, 9 patients with respiratory failure, 11 patients with renal failure and 6 patients with disseminated intravascular coagulation.

Obstructive biliary disease in childhood is not common, but should be considered in the differential diagnosis of a child with jaundice, abdominal pain, or an abdominal mass. We have reviewed the experience at Vanderbilt Children's Hospital from 1970 to 1985, during which 87 children 18 years of age or younger with biliary tract disease were seen. Twelve patients (14%) had congenital disorders including choledochal stenosis, Caroli's disease, choledochal cyst, teratoma of the common hepatic duct and common bile duct, congenital septate biliary tree, and isolated atresia of the distal common bile duct. Thirty patients had neonatal cholestatic syndromes, and 37 had calculous disease of the gallbladder or extrahepatic bile ducts. Three patients had obstruction of the common bile duct caused by fibrosing pancreatitis. Two had sclerosing cholangitis. Obstruction of the common bile duct was caused by metastatic neoplasm in three patients. We discuss principles of diagnosis and management.

Forty patients over 70 years of age with acute pancreatitis were studied. The most common cause of pancreatitis was biliary tract disease (14 patients, 35 percent). Twelve patients (30 percent) were discharged with a diagnosis of idiopathic pancreatitis, but tests such as endoscopic retrograde cholangiopancreatography that might have established the cause of disease were frequently not employed. Eight of the 40 patients died, for a mortality rate of 20 percent. Significant morbidity occurred in an additional seven (17.5 percent). Multisystem failure was the cause of death in all eight patients, and only two patients with multisystem failure survived. The mortality rate was significantly higher in those patients with postoperative pancreatitis. Acute pancreatitis in the elderly carries a grave prognosis. All patients should undergo thorough evaluation, as biliary tract disease is the most common cause. Cholecystectomy should be performed in those with biliary disease to prevent recurrent attacks.

Bile reflux into the pancreatic duct after impaction of a stone in a common pancreaticobiliary channel has been suggested to be the initiating factor in gallstone pancreatitis. Such reflux would require that the impacted stone be smaller than the length of the common channel. The incidence of common channels was studied and gallstone size was compared with common channel length in patients with gallstone pancreatitis and those with cholelithiasis or choledocholithiasis without pancreatitis. Sixty-seven per cent of patients with gallstone pancreatitis had a common channel present on intraoperative cholangiography versus 32% of patients with cholelithiasis or choledocholithiasis without pancreatitis (p less than 0.005). Common channel length was greater than the diameter of the smallest stone in nine of 27 patients with gallstone pancreatitis and in 13 of 109 patients with cholelithiasis or choledocholithiasis without pancreatitis (p less than 0.025). In conclusion, common channels are more frequent in patients with gallstone pancreatitis than in patients with other biliary tract disease. Furthermore, gallstone pancreatitis is associated with stones that are smaller than the common channel, which favors obstruction of both pancreatic and bile ducts while allowing reflux of contents between them.

No single pathophysiologic factor has been identified as the cause of recurrent acute pancreatitis. A systematic search should be undertaken in every patient to identify one of a myriad of factors that have been shown to play a part in causing this distressing illness. The abuse of alcohol remains the likeliest cause, and further research may reveal an inborn error of metabolism that jeopardizes some people. Biliary tract disease, gallstones, choledochal cyst, papillary stenosis, and duodenal diverticula show a clear relationship. Metabolic disorders such as hypercalcemia, hyperlipidemia, and hyperparathyroidism remain suspect. Systemic illnesses such as systemic lupus erythematosus and cystic fibrosis must be considered. Development anomalies such as pancreas divisum may precipitate acute pancreatitis through aberrant anatomic structures. Cancer must always be disproved. Not yet firmly established but worthy of thorough investigation are uncommon causes, such as the ingestion of certain drugs or combinations of drugs and trauma, either recent or past. Pancreatitis remains frightening for those with the disease and puzzling and frustrating for the medical people who treat it. A careful history and investigation in accordance with a systematic diagnostic plan that includes many disparate factors will lead to identification of the cause in the majority of patients.

Since the natural history of pancreatitis associated with cholelithiasis is one of recurrence, surgery for the biliary tract disease is mandatory. But appropriate timing of the surgery remains controversial. Seventy-eight patients have been treated with early surgery once a diagnosis of cholelithiasis associated pancreatitis was made. Eighteen patients had previous episodes of nonalcoholic pancreatitis. Utilizing Ranson's prognostic signs, 52 patients had mild pancreatitis and 26 severe. Sixty-eight patients (87%) had surgery within 72 hours after admission and ten patients (13%) within 5 days. All patients had a cholecystectomy and operative cholangiogram performed. Fifty-six (72%) positive operative cholangiograms were obtained and common bile duct exploration revealed choledocholithiasis in 42 patients (75%). No mortality occurred, and four had six complications including mild persistent pancreatitis (two), wound infection (one), urinary tract infection (one), cardiac arrhythmia (one) and heart block requiring permanent pacemaker (one). The average hospital stay was 10.4 days. T-tube cholangiogram done prior to discharge was normal in all patients, and there have been no episodes of recurrent pancreatitis. Early definitive surgery for pancreatitis associated with cholelithiasis is recommended and can be accomplished with minimal morbidity and mortality coupled with judicious utilization of hospital resources.

The incidence of pancreatitis associated with biliary tract disease is high in certain parts of the world, including Israel. Sometimes, pancreatitis is the first or only manifestation of gallstone disease. However, this may be accompanied by a normal oral or intravenous cholangiogram. Between 1968 and 1980, 173 patients with acute pancreatitis were treated at the Hadassah University Medical Center in Jerusalem. One hundred and two patients (59%) suffered from proven biliary tract disease. In 36 of these 102 patients, repeat preoperative oral and intravenous cholecystograms failed to demonstrate disease in the biliary system. All were referred to surgery on the basis of a high index of suspicion only. At surgery, acute or chronic cholecystitis were found in all cases; gallstones were found in 32 and some degree of pancreatitis in 32. Operative cholangiography demonstrated a common entrance of the ductus choledochus and the pancreatic duct with reflux of contrast material into the pancreatic duct in at least 52.8% of the cases. In 14 patients (38.9%), palpation and cholangiography did not reveal stones and only bile aspiration and filtration through gauze demonstrated many tiny stones. All patients underwent cholecystectomy, and 11 additionally had a common duct exploration. The follow-up period ranged from 2 to 12 years (mean 7 years) with no signs or symptoms of recurrent pancreatitis or biliary tract disease. It has become our practice to attempt proving gallbladder disease radiographically in all cases of recurrent pancreatitis with no other known etiologic background. Failing this, surgical exploration of the biliary system is undertaken.(ABSTRACT TRUNCATED AT 250 WORDS)

Previous studies have suggested that chronic alcohol consumption in man is associated with an increased secretion of pancreatic enzymes. Precise quantitation of the output of protein and trypsin in the interdigestive state has not been possible because of large variations and small volume of pancreatic juice. We utilized a multilumen, marker-perfused duodenal catheter to simultaneously monitor intraluminal pressures and collect mixed duodenal juice at the ligament of Treitz in five groups of patients: normal volunteers (group I), alcoholics without pancreatitis (group II), alcoholics who had recovered from acute pancreatitis (group III), alcoholics with chronic pancreatitis (group IV), and nonalcoholics who had recovered from acute pancreatitis secondary to biliary tract disease (group V). The output of trypsin and protein during 30 min of phase II and 60 min of CCK-OP 40 ng/kg/hr was determined in each group. The output of trypsin during phase II was 1.3 +/- 1.2 and 3.0 +/- 2.5 mg/kg/hr in groups II and III, respectively, compared to 0 +/- 0.1 in group IV (normal = 0.6 +/- 0.5). The outputs in group V were similar to normals. The output of protein during the interdigestive state was 15.7 +/- 13.7 mg/min in group III, compared to 4.5 +/- 3.6 in normals (group I). The duodenal contraction rate was 4.6 +/- 3.0 and 3.3 +/- 2.7 contractions/min in groups III and II, respectively (significantly greater than the normal rate of 2.2 +/- 1.5).(ABSTRACT TRUNCATED AT 250 WORDS)

FOR MANY DECADES TWO TYPES OF ACUTE PANCREATITIS HAVE BEEN RECOGNIZED: the edematous or interstitial and the hemorrhagic or necrotic. In most cases acute pancreatitis is associated with alcoholism or biliary tract disease. Elevated serum or urinary alpha-amylase is the most important finding in diagnosis. The presence of methemalbumin in serum and in peritoneal or pleural fluid supports the diagnosis of the hemorrhagic form of the disease in patients with a history and enzyme studies suggestive of pancreatitis. There is no characteristic clinical picture in acute pancreatitis, and its complications are legion. Pancreatic pseudocyst is probably the most common and pancreatic abscess is the most serious complication. The pathogenetic principle is autodigestion, but the precise sequence of biochemical events is unclear, especially the mode of trypsinogen activation and the role of lysosomal hydrolases. A host of metabolic derangements have been identified in acute pancreatitis, involving lipid, glucose, calcium and magnesium metabolism and changes of the blood clotting mechanism, to name but a few. Medical treatment includes intestinal decompression, analgesics, correction of hypovolemia and other supportive and protective measures. Surgical exploration is advisable in selected cases, when the diagnosis is in doubt, and is considered imperative in the presence of certain complications, especially pancreatic abscess.
