Liver biopsy was done at the time of operation in 125 consecutive upper abdominal procedures to assess the incidence of unsuspected or undiagnosed hepatic abnormalities. Specifically excluded were hepatic lesions unexpectedly identified at laparotomy. Sixty-seven percent of the liver biopsy specimens were abnormal, the most frequent findings being fatty metamorphosis, cholestasis, triaditis, fibrosis, inflammatory infiltrate, cholangitis, cirrhosis, and hepatitis. The most frequent operation performed was cholecystectomy. In 63 patients with chronic cholecystitis, there was a 51% incidence of abnormal liver histology, while in nine patients with acute cholecystitis, the incidence was 78%. In 83% of all other operations, abnormal liver biopsy specimens were identified. Bile leakage, hemorrhage, and infection did not occur in this series, despite inclusion of patients with severe biliary obstruction, abnormal clotting factors, and intra-abdominal sepsis. New techniques of histochemical enzyme analysis and electron microscopy are expected to enhance the clinical correlation of occult hepatic lesions. We conclude that liver biopsy in a safe, informative adjunct to all upper abdominal procedures.

A retrospective analysis of complications arising from 300 consecutive attempts at endoscopic retrograde cholangiopancreatography (ERCP) in 278 patients was undetaken to determine the rate and severity of complications. An over-all complication rate of 5% (15 cases) was documented. Complications were categorized in terms of those arising from endoscopy itself or from the administration of pharmacological agents (7 cases), and those observed after the injection of radioopaque contrast into the biliary tree or pancreas (8 cases). Complications which might be considered coincidental to a patient's underlying illness were not excluded. Complications were significantly more frequent after injection of diseased duct systems. Brief, self-limited pancreatitis after retrograde pancreatography occurred in 5 of 90 patients with pancreatic disease. No cases of pancreatitis were observed after retrograde pancreatography in 102 patients without pancreatic disease X2 = 5.82, P less than 0.025). Sepsis occurred after retrograde cholangiography in 3 of 56 patients with extrahepatic biliary obstruction. In the absence of extrahepatic obstruction, cholangiography was performed without complication in 85 cases (X2 = 3.62, P less than 0.1), although 25 of these had intense cholestasis due to hepatic parenchymal disease. This analysis provides the basis for modifications of ERCP technique and management that may reduce the future incidence of complications. This study suggests that the incidence and severity of complications that arise from ERCP compare favorably with procedures of equivalent diagnostic yield.

A retrospective study was carried out of 74 elderly patients with obstructive jaundice undergoing percutaneous transhepatic cholangiography (PTC) and/or percutaneous biliary drainage (PBD) in order to assess the effect of prophylactic antibiotics on the incidence of fever and sepsis complicating these procedures. Seventeen patients underwent PTC alone, while 57 had both PTC and PBD. Fifty-three patients had either primary or metastatic malignancy. In the other patients with benign disease, choledocholithiasis was the most common reason for undertaking these procedures. Prophylactic antibiotics were given in 80% of cholangiographies and 93% of biliary drainage procedures. There was an overall incidence of sepsis of 13.5%. Enterobacter cloacae and Acinetobacter anitratus were the most common blood culture isolates in patients with malignant biliary obstruction. The incidence of fever was no different between patients who underwent PTC alone compared with those who had PTC and PBD. Of 24 patients who developed fever, two died secondary to sepsis. Although there was no difference in the rate of sepsis and febrile episodes between the two groups, the risk of septic episodes and mortality emphasizes the need for antibiotic prophylaxis and early therapy in elderly patients undergoing percutaneous biliary drainage procedures.

The biliary excretion of imipenem-cilastatin studied by endoscopic cannulation of the common bile duct in patients with complete obstruction and in a group without obstruction showed that despite a 24-h prophylaxis, the bile obtained from patients with obstruction immediately after cannulation contained neither imipenem nor cilastatin, while there were 2 and 5% of peak concentrations in serum for imipenem and cilastatin, respectively, in the bile from patients without obstruction. Biliary excretion of both compounds increased rapidly after decompression, reaching a maximum of 15% of peak levels in serum within 2 h. Twenty-four hours after drainage, the biliary excretion of the drugs further improved. We conclude that since biliary obstruction impairs excretion of antibiotics, drainage is necessary for the control of sepsis in obstructed cholangitis.

For four years up to December 1987, 190 patients (median age 73 years) with proximal malignant biliary obstruction were treated by endoscopic endoprosthesis insertion. Altogether 101 had cholangiocarcinoma, 21 gall bladder carcinoma, 20 local spread of pancreatic carcinoma, and 48 metastatic malignancy. Fifty eight patients had type I, 54 type II, and 78 type III proximal biliary strictures (Bismuth classification). All patients were either unfit or unsuitable for an attempt at curative surgical resection. A single endoprosthesis was placed initially, with a further stent being placed only if relief of cholestasis was insufficient or sepsis developed in undrained segments. The combined percutaneous-endoscopic technique was used to place the endoprosthesis when appropriate, after failed endoscopic endoprosthesis insertion or for second endoprosthesis placement. Full follow up was available in 97%. Thirteen patients were still alive at the time of review and all but one had been treated within the past six months. Initial endoprosthesis insertion succeeded technically at the first attempt in 127 patients, at the second in 30, and at a combined procedure in a further 13 (cumulative total success rate 89% - type I: 93%; type II: 94%; and type III: 84%). There was adequate biliary drainage after single endoprosthesis insertion in 152 of the 170 successful placements, giving an overall successful drainage rate of 80%. Three patients had a second stent placed by combined procedure because of insufficient drainage, giving an overall successful drainage rate of 82% (155 of 190). The final overall drainage success rates were type I: 91%; type II: 83%; and type III: 73%. The early complication rates were type I: 7%; type II: 14%; and type III: 31%. The principle early complication was clinical cholangitis, which occurred in 13 patients (7%) and required second stent placement in five. The 30 day mortality was 22% overall (type I: 14%; type II: 15%; and type III: 32%) but the direct procedure related mortality was only 3%. Median survival overall for types I, II, and III strictures were 21, 12, and 10 weeks respectively but survival was significantly shorter for metastatic than primary malignancy (p<0.05). Endoscopic insertion of a single endoprosthesis will provide good palliation of proximal malignant biliary obstruction caused by unresectable malignancy in 80% of patients. Second stents should be placed only if required. Extensive structuring because of metastatic disease carries a poor prognosis and careful patient selection for treatment is requires.

We measured serum interleukin-6 (IL-6) and acute-phase proteins, alpha 1-acid glycoprotein (AGP) and alpha 2-macroglobulin (alpha 2M), after a retrograde intrabiliary bacterial infection in rats with biliary obstruction. Maximum serum IL-6 was obtained at 6 h in rats following inoculation of bacteria (10(6) CFU/ml E. Coli) in the bile duct and it was higher than that observed in rats undergoing a bile duct ligation or a laparotomy. There was a strict relationship between the level of IL-6 at 6 h and the modified levels of AGP and alpha 2M at 48 h. AGP and alpha 2M levels were the highest in sera of rats with bile duct infection as compared with those found in sera of rats with bile duct ligation or laparotomy. After inoculation of E. Coli or E. Fecalis, blood IL-6 level was always higher at 6 h in inferior vena cava as compared with that found in the supra hepatic vein. These results indicate that IL-6 is synthesized after a biliary sepsis and that its blood level is higher in the systemic circulation than in the local circulation.

We report two cases of malignant biliary obstruction in whom percutaneous transhepatic biliary drainage has contributed to patient survival of more than 5 years. To our knowledge, this represents the first such case report in the literature. Both patients suffered biliary obstruction from poorly differentiated adenocarcinoma, in all likelihood from the head of the pancreas. Morbidity has been low with only two episodes of significant sepsis and one episode of GI haemorrhage in one patient and both patients were able to enjoy an excellent quality of life. These cases demonstrate that percutaneous biliary drainage has a place not only in the short term palliation of patients with malignant biliary obstruction, but in the long term as well.

Sepsis is a major cause of morbidity and mortality in infants with cholestatic jaundice. This may be attributed to altered host defense mechanisms. Fungal infection frequently occurs in immunocompromised patients. This study evaluates the effect of biliary obstruction on blood clearance and organ localization of radiolabeled viable Candida albicans. Male Sprague-Dawley rats (140 to 150 g) were placed in 2 groups. Group I (n = 30) were sham-operated controls. Group II (n = 90) underwent ligation and division of the distal common bile duct (CDL). At 1, 2, and 3 weeks following CDL, 10(7) cells/mL radiolabeled viable C albicans were injected via the tail vein. The final distribution of the organisms was calculated and expressed as the mean percent of radiolabeled organisms per gram and per total organ. Blood clearance of C albicans was similarly rapid in both groups. However, there was a significant decrease in the trapping of fungi by the rat liver Kupffer cells (20.3% +/- 7.9% v control 42.5% +/- 15%; P greater than .001), and increased pulmonary localization of bacteria 3 weeks following CDL (53.6% +/- 13.2% v control 41.4% +/- 6.4%). The significant decrease in liver trapping and increased lung localization of C albicans in CDL rats, may result in systemic reemergence of fungi and play a role in the susceptibility to fungal infection in jaundiced subjects.

Patients with the acquired immune deficiency syndrome (AIDS) frequently develop hepatic dysfunction. Although hepatic injury may indirectly result from malnutrition, hypotension, administered medications, sepsis, or other conditions, the hepatic injury is frequently due to opportunistic hepatic infection, directly related to AIDS. Infection with Mycobacterium avium intracellulare typically occurs in patients with advanced immunocompromise and with systemic symptoms due to widely disseminated infection. In contrast, hepatic tuberculosis often occurs with less advanced immunocompromise. Cytomegaloviral infection may produce a hepatitis. Cytomegaloviral and cryptosporidial infections have been implicated as causes of acalculous cholecystitis and of a secondary sclerosing cholangitis. About 10-20% of patients with AIDS have chronic hepatitis B infection. These patients tend to develop minimal hepatic inflammation and necrosis. The clinical findings in patients with hepatic cryptococcal infection are usually due to concomitant extrahepatic infection. Hepatic histoplasmosis usually develops as part of a widely disseminated infection with systemic symptoms. Hepatic involvement by Kaposi's sarcoma is rarely documented ante mortem because an unguided liver biopsy is an insensitive diagnostic procedure. Patients with non-Hodgkin's lymphoma of the liver typically have lymphadenopathy, hepatomegaly, and systemic symptoms. As a pragmatic approach, patients with liver dysfunction and HIV-related disease should have a sonographic or computerized tomographic examination of the liver. Patients with dilated bile ducts should undergo endoscopic retrograde cholangiopancreatography because opportunistic infection may produce biliary obstruction. Patients with a focal hepatic lesion should be considered for a guided liver biopsy. Patients with a significantly elevated serum alkaline phosphatase level should be considered for a percutaneous liver biopsy. When performed for these indications, liver biopsy will demonstrate a significant disease involving the liver in about 50% of patients with AIDS and in about 25% of patients who are HIV seropositive but who are not known to have AIDS. The clinical impact of a diagnostic biopsy is blunted by a lack of efficacious therapy for many opportunistic infections.

Sepsis is a major cause of morbidity and mortality in infants with cholestatic jaundice. Previous studies have shown that biliary obstruction in rats causes a significant decrease in hepatic phagocytosis of viable Escherichia coli. This study tests this hypothesis and further evaluates whether the impaired function of the reticuloendothelial system of the liver (Kupffer cells) can be reversed by the relief of the biliary obstruction. Male Sprague-Dawley rats (weighing 140 to 150 g) were placed in three groups. Group I (n = 10) consisted of sham-operated controls. In Group II (n = 30), ligation and division of distal common bile duct (CDL) was performed. Group III (n = 30) underwent choledochoduodenostomy 2 weeks following ligation and division of common bile duct. At 1, 2, and 3 weeks following the operation, 10(9) 35S-radiolabeled viable E coli were injected intravenously via the tail vein. At 10 minutes, bacterial distribution in the liver, spleen, kidneys, and lungs was determined. Tissue samples (50 to 100 mg) from each organ were processed for liquid scintillation counting. The final distribution of bacteria was calculated from the input specific activity (dpm/bacteria) and expressed as the mean percentage of injected viable E coli per gram of tissue and per total organ weight. There was a significant decrease in the trapping of bacteria by the liver's Kupffer cells in rats in group II, at 2 and 3 weeks following CDL (45.0% +/- 14.0% and 15.1% +/- 4.9%, respectively, v controls 75.9% +/- 13.7%; P less than .005).(ABSTRACT TRUNCATED AT 250 WORDS)
