[Liver transplantation for biliary tract disease].

Biliary tract diseases have always been one of the important indications for liver transplantation. These biliary tract diseases include congenital atresia of biliary duct, biliary diseases with tendency of malignant transformation, malignant biliary diseases, primary biliary cirrhosis, and secondary biliary cirrhosis. The right time to consider liver transplantation for the above biliary diseases includes situations when transplantation is the only approach to treat the disease, the only effective approach to treat the disease, or one of the effective approaches to treat the disease. Currently there is still no commonly accepted pre-operative evaluation standard for biliary disease-related liver transplantation. However, it is important to obey the following principles. First, the diagnosis should be confirmed; secondary, the necessity or urgency of the liver transplantation should be clarified; and third, the patient and his/her family should understand the whole procedure of transplantation the risk and advantage of the surgery, and the potential life-long intake of immunosuppressors. This article will briefly review all these relavant issues based on the authors' personal experience and clinical cases.

Utility and accuracy of ultrasonically measured gallbladder wall as a diagnostic criteria in biliary tract disease.

Biliary tract sonography has achieved wide acceptance as a screening test for chronic calculous disease. However, the clinical usefulness of biliary sonography is limited by the inability of this test to identify patients with acalculous cholecystitis or to separate patients with calculous cholecystitis from those with asymptomatic calculi. A prospective blinded study of 106 patients undergoing cholecystectomy was performed to determine if, cholecystosonography could visualize the gallbladder wall accurately and to evaluate gallbladder wall thickening as a predictor of disease. Of these patients, 88 had a sonographically visible gallbladder wall and in 95% of the patients the ultrasonic and direct surgical measurements of the gallbladder wall agreed within 1 mm. To determine the sonographic size range of gallbladder wall thickness in the normal population, the width of the gallbladder wall in the fasting state was measured in 100 patients without biliary tract disease. One percent of the normal population had thickened gallbladder walls, in contrast to 96% of the patients with acute calculous or acalculous cholecystitis. Gallbladder wall thickness appears to be an accurate noninvasive technique for diagnosing patients with acute calculous and acalculous cholecystitis in the absence of other entities which thicken the gallbladder wall such as ascites and hypoproteinemic states.

Endoscopic papillotomy in the geriatric patient with complicated biliary-tract disease.

Biliary-tract disease is not only more common in the geriatric population but carries an increased surgical risk. Described is a series of 10 middle-aged and elderly patients who had stones in the common bile duct associated with significant underlying medical illness or peri-ampullary pathologic changes. They were successfully treated by endoscopic papillotomy. The 80 percent success rate in such critically ill patients suggests that endoscopic papillotomy might be used as the initial treatment modality in aging patients with amenable biliary-tract disease.

Biliary tract excretion of cefazolin, cephalothin, and cephaloridine in the presence of biliary tract disease.

The biliary tract excretion of three cephalosporins, cefazolin, cephaloridine, and cephalothin, was compared in patients with biliary tract disease. In the absence of obstruction, mean antibiotic levels in bile from gall bladder and common duct in patients undergoing cholecystectomy were highest for cefazolin (17 and 31 mug/ml, respectively) than either cephaloridine (7 and 9 mug/ml) or cephalothin (1 and 4 mug/ml). Biliary tract levels generally paralleled serum levels. In no patient with cystic duct obstruction were any of the cephalosporins detectable in appreciable amounts in gall bladder bile. In patients with T-tube drainage given each of the three different cephalosporins on separate days, concentrations of cefazolin in bile were many-fold higher than either cephaloridine or cephalothin. Peak levels of cefazolin in T-tube bile averaged 51 mug/ml after intravenous and 26 mug/ml after intramuscular administration, whereas mean peak levels of cephalothin and cephaloridine were only 6 and 16 mug/ml, respectively. Here, too, T-tube levels reflected serum concentrations and obstruction to biliary flow impaired excretion of each of the drugs.

The role of microorganisms in biliary tract disease.

The biliary tract is normally sterile, but bile-tolerant bacteria are frequently isolated from patients with cholecystitis. Since the identification of about 25 Helicobacter species, some of which may grow in bile, studies have addressed the role of these organisms in primary biliary cirrhosis, primary sclerosing cholangitis, and cholelithiasis. Most of these bacteria show the presence of Helicobacter DNA or antigens in the bile tract and in liver samples. Altogether, data from studies on biliary and hepatic diseases, as well as pancreatic disorders, suggest that bile-tolerant Helicobacter species may induce a chronic infection with possible malignant transformation.

Experience with percutaneous transhepatic cholangioscopy (PTCS) in the management of biliary tract disease.

BACKGROUND: Biliary tract disorders often present significant management difficulties, particularly in patients who are poor surgical candidates. Percutaneous transhepatic cholangioscopy (PTCS) is an infrequently utilized alternative that might offer significant therapeutic benefit. We reviewed our experience with the use of this modality as a definitive therapy for biliary tract disorders. METHODS: Patient records at the Atlanta VAMC and Emory University hospitals were reviewed. We identified 17 patients who had undergone 25 PTCS interventions between August 1994 and December 1998. The indications for PTCS included dilatation of biliary-enteric anastomoses in four patients, biliary stone removal (with or without lithotripsy) in eight patients, stricturoplasty in four patients, biopsy of suspected biliary neoplasms in seven patients, and removal of obstructing clot in one patient. Most procedures (n = 17) were performed through percutaneous transhepatic tracts (12-18 Fr) that were <1 week old. All tracts were dilated to operating size on the day of the procedure. All patients received periprocedural antibiotics. RESULTS: The interventions were successful in seven of eight stone removals, four of five stricturoplasties, three of four anastomotic dilatations, seven of seven biopsies, and the single clot removal. The only complication involved one episode of hemobilia, requiring angio-embolization of a small branch of the right hepatic artery. CONCLUSIONS: PTCS is a safe, useful, and well-tolerated adjunct to the more common endoscopic and surgical techniques for managing complicated biliary tract disorders. Our experience suggests that PTCS can be performed early, without prolonged sequential dilatation of the percutaneous transhepatic tract, and may allow avoidance of operation in high-risk surgical candidates.

Biliary tract disease as a risk factor for Plesiomonas shigelloides bacteraemia: a nine-year experience in a Hong Kong hospital and review of the literature.

We report the epidemiology, clinical disease spectrum, treatment, and outcome of Plesiomonas shigelloides bacteraemia in our hospital over a nine-year period and compare the characteristics of patients with P. shigelloides bacteraemia in our hospital with those reported in the literature. During the nine-year period (1995--2003), a total of seven patients developed P. shigelloides bacteraemia. All cases occurred during the late spring, summer, and early autumn (May-October). All patients were over 75 and had underlying diseases (biliary tract diseases in four and malignancies in three). Six had acute cholangitis and five had polymicrobial bacteraemia. Overall two patients died. Compared with patients with P. shigelloides bacteraemia reported in the literature, patients with P. shigelloides bacteraemia in our hospital were associated with old age (P<0.001), underlying biliary tract diseases (P<0.001), acute cholangitis (P<0.001), and polymicrobial bacteraemia (P<0.001). There are major geographical differences of disease association in P. shigelloides bacteraemia. The sources of P. shigelloides in our patients were probably in the gastrointestinal tract.

Efficacy of plain abdominal radiography in patients with biliary tract disease.

A retrospective review was performed to determine the usefulness of plain abdominal radiographs in patients presenting to the emergency department with gallbladder disease. Patients with the clinical diagnosis of biliary tract disease were divided into two groups: those with confirmed biliary tract disease and those who did not have gall bladder disease. There were no major radiologic findings (pneumoperitoneum, pneumobilia, or bowel obstruction) in any patient with biliary tract disease. No significant difference was noted in the incidence of minor radiologic findings (right upper quadrant calcification, mild ileus and right basilar atelectasis) in patients with biliary colic and acute cholecystitis. Additionally, there was no significant difference in minor findings between patients with biliary tract and nonbiliary tract disease. Plain abdominal radiographic findings were found to be nonspecific in patients with gallbladder disease and not useful in differentiating between patients with biliary colic and acute cholecystitis. Our results also suggest that plain abdominal radiographic findings are not useful in differentiating between patients with and without biliary tract disease, although the selection of patients without biliary tract disease may have biased this finding.

Route of infection in extrahepatic biliary tract disease. II: Bacterial recovery from gallbladder bile and gallbladder wall in human biliary tract disease.

Bacterial recovery from gallbladder wall and gallbladder bile was investigated in 73 patients with extrahepatic biliary tract diseases. The technique of anaerobic culture was based on the use of a 'glove-box' and prereduced anaerobically sterilized media. Transport of samples was based on evacuation of atmospheric air with oxygen-free carbon dioxide and a transport time less than 30 minutes. When samples of bile and tissue were obtained simultaneously before operations on the biliary tract were begun and handled by one of the authors to avoid contamination, no significant difference in bacterial recovery between bile and tissue was observed. If samples were handled routinely by the staff or if biopsy from the gallbladder wall was not obtained until after operation on the biliary tract was finished, bacterial recovery from gallbladder tissue was significantly more frequent compared to bile. Under these last mentioned circumstances, the difference in bacterial recovery was due to bacterial species like Staph. aureus, Staph. albus, P. acnes and Difteroids.

Biliary excretion of aztreonam in patients with biliary tract disease.

The biliary excretion of aztreonam was studied in 10 post-cholecystectomy patients with T-tube biliary drainage (group A) and four other subjects with obstructive biliary tract disease who had recent placement of external biliary drainage (group B). Maximum biliary levels ranged from 9.7 to 88.2 micrograms/ml (mean, 42.9 +/- 7.9 micrograms/ml) and occurred 2.4 h after injection of a single 1-g dose intravenously. Peak biliary levels observed in group B patients were approximately one-third those in group A. Cumulative 12-h biliary excretion (group B) accounted for 0.18 +/- 0.06% of the total dose. In the same period, urinary excretion accounted for 65 to 72% of the total dose. The lower biliary levels of aztreonam observed in group B patients relative to those in group A suggest that in patients with total biliary tract obstruction the liver may not recover full secretory capacity, at least within 3 to 7 days after biliary decompression.
