Using a minimally compliant infusion system and a triple-lumen pressure recording catheter, we obtained endoscopic manometric measurements from both the common bile duct and pancreatic duct segments of the sphincter of Oddi (SO) in 58 patients. Fifteen patients (ages 27-69) had the diagnosis of functional abdominal pain, 19 patients (ages 30-76) had partial biliary obstruction, and 24 patients (ages 15-80) had idiopathic acute recurrent pancreatitis. Resting ductal pressure was similar in the common bile duct and pancreatic duct in all patient groups. In the group with functional pain, basal SO pressure was similar, whether obtained from the common bile duct or pancreatic duct sphincteric segment. Eight of 19 patients with partial biliary obstruction had elevated basal SO pressure. Five of these eight patients had elevated basal SO pressure confined exclusively to the common bile duct segment of the sphincter, while three patients had elevated basal SO in both segments. Conversely seven of 24 patients with acute recurrent pancreatitis had an elevated basal SO pressure, with five patients having pressure elevation only in the pancreatic duct segment while two patients had abnormal basal SO pressure in both segments. We conclude that selective cannulation of the common bile duct and/or the pancreatic duct during manometric study of the SO is necessary in order to diagnose segmental SO dysfunction responsible for partial biliary obstruction or episodes of acute recurrent pancreatitis.

Cholangitis is an infection of the biliary ductal system that results from the combination of bactibilia and biliary obstruction. Choledocholithiasis has been the leading cause of cholangitis. However, in recent years, especially at tertiary referral centers, nonoperative biliary manipulations, often in patients with unresectable malignancies, have become the most common cause of cholangitis. As a result, the complete triad of fever and chills, jaundice, and abdominal pain, as originally described by Charcot, is now seen less frequently. Most patients still have leukocytosis and abnormal liver function tests, but many patients with indwelling tubes may develop cholangitis without significant jaundice. E. coli, Klebsiella species, and the enterococci remain the most frequently isolated organisms, and anaerobes including Bacteroides fragilis are recovered in 15% to 30% of patients. However, Enterobacter and Pseudomonas species, as well as yeasts, are now being isolated more frequently from patients with indwelling tubes, who often have been treated previously with antibiotics. Computed cholangiography usually is necessary to determine the cause and site of biliary obstruction. In the majority of patients with cholangitis, cholangiography can be delayed until the patient has been afebrile for a minimum of 24 to 48 hours. Initial therapy includes bowel rest, intravenous fluids, and antibiotics. Many antibiotic regimens are now available to cover the gram-negative aerobes, the enterococcus, and the anaerobes that are likely to be causing the biliary infection. The combination of a penicillin and an aminoglycoside has been the gold standard. However, recent studies suggest that the newer broad-spectrum penicillins provide adequate therapy for these patients. Only a small percentage (5%-10%) of patients with toxic cholangitis require emergency biliary decompression. The choice of percutaneous or endoscopic drainage should be made on the basis of the presumed site and cause of obstruction as well as local expertise. The nature of the biliary obstruction may be the most important determinant of outcome. At present, patients with end-stage malignant obstruction account for most of the deaths, whereas approximately 95% of patients survive an episode of cholangitis.

To assess the relief of pain provided by a side-to-side lateral pancreaticojejunostomy (LPJ), we analyzed 19 patients with chronic pancreatitis operated on from 1973 to 1983. Fourteen patients were chronic alcoholics; abdominal pain was the indication for the operation in most patients; one patient died postoperatively. The pain was relieved in all 18 survivors, from 12 to 72 months in 15; in three the pain has recurred, suggesting that LPJ is effective in ablating the pain in patients with chronic pancreatitis, provided the pancreatic duct measures more than 6 mm in diameter, the length of the LPJ is at least 6 cm, and patients abstain from alcohol ingestion. CT adequately assesses pancreatic duct dilatation. One fourth of the patients also required choledochoduodenostomy to relieve biliary obstruction caused by the chronic pancreatitis.

The occurrence of hepatobiliary disease with or without jaundice during pregnancy provides both the hepatologist and obstetrician with an interesting and urgent diagnostic challenge. Advances in our understanding and management of liver disorders unique to pregnancy and hepatobiliary disease in general have resulted in a significant improvement in the outcome for both mother and fetus. Certain disorders such as acute fatty liver of pregnancy and hepatic haemorrhage associated with toxaemia should be considered medical emergencies and delay in diagnosis of these conditions will probably adversely affect maternal and fetal outcome. A careful clinical history, physical examination, appropriate laboratory tests and radiological investigations should allow a diagnosis within 24-48 hours of presentation. Liver biopsy is rarely required. A careful history may provide important information. Does the patient have pre-existent liver disease? Has there been contact with hepatitis, intravenous drug abuse or any other factor predisposing to acute viral hepatitis? Does the patient have a family history of pruritus and/or jaundice to suggest intrahepatic cholestasis of pregnancy? Is the patient's alcohol consumption excessive? Has the patient received any hepatotoxic medications? Has there been abdominal pain and/or fever to suggest gallstones, hepatic bleeding or acute fatty liver of pregnancy? Laboratory investigations may give valuable diagnostic clues. Marked aminotransferase elevation would suggest acute viral or 'ischaemic' hepatitis. Haematological features of microangiopathic haemolysis would point towards toxaemia or AFLP. Hepatitis A and B serological tests may be helpful in viral liver disease. Radiological investigations may be indicated depending on the clinical context. Abdominal ultrasonography may be useful in the diagnosis of gallstones, biliary obstruction, liver tumours or intrahepatic bleeding. Fatty infiltration of the liver may be diagnosed by ultrasonography but computed tomography (CT) of the abdomen is probably more reliable for a diagnosis of acute fatty liver of pregnancy as it allows measurement of liver density which is typically reduced by fatty infiltration. CT scanning is also probably more valuable than ultrasound in assessing the extent of capsular rupture and haemorrhage into the liver and peritoneal cavity.

Twelve patients with small-cell lung cancer seen during a 30-month period had jaundice at diagnosis. Five patients had a pancreatic metastasis resulting in extrahepatic biliary obstruction, and seven had diffuse hepatic metastases without extrahepatic obstruction. All patients with pancreatic masses had complete (or nearly complete) resolution of jaundice and abdominal pain within 3 weeks of starting chemotherapy. Patients with extensive liver metastases usually remained icteric in spite of intensive treatment. Three patients with pancreatic metastases survived more than 12 months after the institution of therapy. No patient presenting with jaundice caused solely by hepatic metastases survived beyond 8 months. Small-cell lung cancer can present with jaundice due to diffuse hepatic parenchymal involvement, which is associated with a poor prognosis, or as a result of extrahepatic biliary obstruction, which has potential for rapid palliation and prolonged survival.

A 43 year-old man with a 15-year history of disseminated Langerhans histiocytosis (LH) in complete clinical remission was admitted with jaundice and abdominal pain. Pathological examination demonstrated LH in the choledochus associated with sclerosing cholangitis in the liver. Immunohistochemistry for S-100 protein and electron microscopy of the choledochus tissue showed Langerhans cell-like elements in the infiltrate. Our findings suggest that, in patients with disseminated Langerhans histiocytosis, liver function should be monitored, particularly, for signs of biliary obstruction, and demonstrate that such a finding is possible in adults.

A prospective study on biliary and pancreatic obstruction during gallstone migration was performed in patients without acute pancreatitis. From January to October 1986, 125 patients with upper abdominal pain due to cholelithiasis were admitted to the hospital. Ultrasonography performed in all patients at admission demonstrated a distal bile duct measuring 7 mm or more in 39 patients, who were monitored for diameter changes of the biliary and pancreatic duct every 24 h and their stools screened for gallstones. Patients underwent surgery at least 8 days after admission. Gallstone migration was found preoperatively in 10 patients, of whom 6 had total serum bilirubin values lower than 2 mg/100 ml. Migration time was accurately determined by the sudden decrease in bile duct caliber. Simultaneous dilatation of biliary and pancreatic duct was found in 4 out of 10 patients with migrating gallstones and in 7 out of 23 patients without gallstone migration, though differences proved non-significant. Acute pancreatitis developed in 2 patients with lithiasis of the distal bile duct who ingested a fatty meal against medical advice. Gallstone migration, even of small stones, was preceded by a period of biliary obstruction. Pain and jaundice before migration were not as frequent as expected.

Most reports of the operative treatment of symptomatic polycystic liver disease (PCLD) are anecdotal or consist of only a small subset of patients in an institution's overall experience treating hepatic cysts. We have reviewed our experience with nine consecutive patients with symptomatic PCLD undergoing operative treatment from 1981 to 1987. Indications for operation include chronic abdominal pain (4 patients), cyst infection (2 patients), biliary obstruction (2 patients), inferior vena cava obstruction (2 patients), and symptomatic abdominal distention (2 patients). The average duration of symptoms leading to operation was 7.8 months. Three types of cystic disease were identified based on gross morphology: dominant cystic disease (3 patients), diffuse cystic disease (4 patients), and mixed cystic disease (2 patients). Operations to treat symptomatic PCLD included unroofing and external drainage of infected cysts (2 operations), simple unroofing (1 operation), cyst fenestration alone (4 operations) and fenestration combined with resection (3 operations). Treatment directed at principally dominant cysts (five patients) was associated with resolution of symptoms and low morbidity and mortality. Treatment directed at diffusely cystic disease (four patients) resulted in significant morbidity and mortality including three deaths. Successful surgical treatment of symptomatic patients with PCLD depends on accurate preoperative identification of patients with symptoms related to one or more dominant cysts. In this setting fenestration or simple unroofing of the dominant cyst is safe and effective treatment. By comparison, extensive fenestration with or without hepatic resection in patients with symptoms attributed to a diffusely cystic liver may be associated with unacceptable morbidity and mortality.(ABSTRACT TRUNCATED AT 250 WORDS)

A 31-year-old patient with sickle-cell disease who had previous cholecystectomy developed acute onset of jaundice and abdominal pain. An endoscopic retrograde cholangiography demonstrated multiple filling defects within the bile ducts. Microscopic examination of "calculi" removed at surgery revealed that a fungal ball composed of Candida was the cause of biliary obstruction in this case. The patient eventually recovered after removal of the fungal masses and intrabiliary instillation of amphotericin.

In a review of pediatric autopsies from 1951 to 1985, we identified 40 cases in which pancreatitis was diagnosed pathologically. Twenty-six of these patients were under 4 years of age, and the male-to-female ratio was 1.5. Six groups of patients were identified: 10 with hepatobiliary disease, including 9 with biliary atresia; 7 with immunosuppressive therapy for tumors (n = 2), leukemia (n = 4) and aplastic anemia (n = 1); 6 with viral infections; 8 with congenital anomalies, including congenital heart disease (n = 3); and 9 with miscellaneous problems. Several patients had surgery and various intercurrent complications. Clinical features attributable to the pancreatitis included vomiting or excessive nasogastric drainage (60%), pleural effusions (40%), and abdominal pain (25%). However, the diagnosis was suspected clinically in only 5 of 40 patients. Our findings suggest several pathogenic mechanisms exist for childhood pancreatitis: biliary obstruction, infections, drug toxicity, immunosuppression (acting in synergy with drug toxicity, trauma, and low-flow states resulting from shock, heart failure, and vasculopathy.
