Endoscopic retrograde cholangiography in the diagnosis of biliary malformations in infants

The differentiation of infantile biliary malformations from primary parenchymal diseases is difficult. The recent development of a pediatric side-viewing endoscope (PJF Endoscope; Olympus Corporation of America) provided an opportunity to investigate the usefulness of endoscopic retrograde cholangiography (ERC) for precise visualization of the extrahepatic biliary passages in infants with persistent cryptogenic cholestasis. ERC was performed in 12 patients, with visualization of the existing extrahepatic bile ducts in 4. The entire biliary system was visualized in one, excluding extrahepatic biliary atresia and choledochal cyst. The reduced caliber of the intrahepatic bile ducts and histological observations in a percutaneous liver biopsy supported the diagnosis of intrahepatic biliary hypoplasia in this case. An intact hepatic portochole cystostomy was documented in one, although the intrahepatic biliary system was not delineated. Atresia of the hepatic bile ducts proximal to the gallbladder was documented in two. Of the eight patients in whom extrahepatic bile ducts were not visualized by ERC, six had extrahepatic biliary atresia confirmed at exploratory laparotomy. The papilla of Vater could not be located in four of these six infants. The remaining two had neonatal hepatitis. ERC may offer a useful alternative to operative cholangiography in selected infants with persistent cholestasis and acholic stools.

Percutaneous transhepatic insertion of a permanent endoprosthesis in obstructive lesions of the extrahepatic bile ducts

A Teflon endoprosthesis for permanent bile drainage was inserted in 13 patients following percutaneous transhepatic puncture and catheterization of the bile duct system. Twelve patients had extrahepatic cholestasis because of a malignant tumor, whereas one patient had chronic inflammation involving the hepatoduodenal ligament (secondary to Crohn's disease) with obstruction of the extrahepatic bile ducts. The drainage periods varied from 1 week to 8 months. The endoprosthesis was regarded as partially effective in seven patients whereas in six cases the drainage through the endoprosthesis was insufficient and external bile drainage through a percutaneous transhepatic catheter was necessary. Infection of the bile duct system during the drainage period with a percutaneous transhepatic catheter and/or bile duct endoprosthesis occurred in 10 patients. Spontaneous dislocation of the endoprosthesis occurred in varying degrees in five patients. One patient developed an intrahepatic aneurysm adjacent to the puncture tract and died because of liver insufficiency following therapeutic embolization of the aneurysm and most of the hepatic arteries by injection of gelfoam particles into the common hepatic artery. Patients in whom palliative treatment by insertion of a permanent bile duct endoprosthesis may be suitable were defined.     

Bile Pulmonary Embolism: Report of a Case and a Review of the Literature

Bile emboli were found at autopsy in the small pulmonary arteries of a 68-year-old man with a past history of polyposis coli who had required percutaneous transhepatic drainage of his biliary tree because of an obstructing ampullary carcinoma. A communication between the biliary tract and a hepatic vein was shown to be due to the catheter. Eight previously reported cases of bile pulmonary emboli have been found. All but one had a clear history of hepatic trauma or intrahepatic abscess. Bile pulmonary embolism is a rare, occasionally fatal, complication of fistulous communication between the biliary tree and the hepatic venous system.

Extrahepatic biliary stenoses after hepatic arterial infusion (HAI) of floxuridine (FUdR) for liver metastases from colorectal cancer.

Hepatic arterial infusion of floxuridine is an effective treatment for unresectable hepatic metastases from colorectal cancer. Despite its pharmacological advantage of higher tumor drug concentration with minimal systemic toxicity, hepatic arterial infusion of floxuridine is characterized by regional toxicity, including hepatobiliary damage resembling idiopathic sclerosing cholangitis (5-29% of treated cases). Unlike previous reports describing biliary damage of both intrahepatic and extrahepatic ducts, a case series of extrahepatic biliary stenosis after hepatic arterial infusion with floxuridine is herein described. Between September 1993 and February 1999, 54 patients received intraarterial hepatic chemotherapy based on continuous infusion of floxuridine (dose escalation 0.15-0.30 mg/kg/day for 14 days every 28 days) plus dexamethasone 28 mg. Twenty-seven patients underwent laparotomy to implant the catheter into the hepatic artery, the other 27 patients receiving a percutaneous catheter into the hepatic artery through a transaxillary access. Five patients (9.2%) developed biliary toxicity with jaundice and cholangitis (3 cases), alterations of liver function tests and radiological features of biliary tract abnormalities. They received from 9 to 19 cycles (mean 14.5 +/- 6.3 cycles) of floxuridine infusion with a total drug delivered dose ranging from 20.3 to 41.02 mg/kg (mean: 31.4 +/- 13.5 mg/kg). Extrahepatic biliary sclerosis was discovered by computed tomography scan and ultrasound, followed by endoscopic retrograde cholangiopancreatography and/or percutaneous cholangiography in 3 cases. Radiological findings included common hepatic duct complete obstruction in 1 case, common hepatic duct stenosis in 2 cases, common bile duct obstruction in 1 case, and intrahepatic bile ducts dilation without a well-recognized obstruction in 1 case. Two patients were treated by sequentially percutaneous biliary drainage and balloon dilation while 1 patient had an endoscopic transpapillary biliary prosthesis placed. Percutaneous or endoscopic procedures obtained the improvement of hepatic function and cholestatic indexes without subsequent jaundice or cholangitis. In two patients suppression of floxuridine infusion allowed the improvement of hepatic function. The present series suggests that in some patients receiving hepatic arterial infusion of floxuridine extrahepatic biliary stenosis may represent the primary event leading to a secondary intrahepatic biliary damage that does not correlate with specific floxuridine toxicity but results from bile stasis and infection, recurrent cholangitis and eventually biliary sclerosis. Aggressive research for extrahepatic biliary sclerosis is advised, since an early nonsurgical treatment of extrahepatic biliary stenosis may prevent an irreversible intrahepatic biliary sclerosis worsening the prognosis of metastatic liver disease.     

Insemination of bile duct carcinoma to the liver after insertion of percutaneous biliary endoprosthesis

Percutaneous transhepatic biliary drainage is widely used to relieve bile duct obstruction which can be caused by bile duct or pancreas carcinomas. Although the incidence is low, insemination of carcinoma along the transhepatic catheter tract is considered to be a serious complication of percutaneous transhepatic biliary drainage. The authors present a case of intrahepatic insemination of bile duct carcinoma along the catheter that subsequently underwent a curative resection consisting of pancreaticoduodenectomy and right hepatic lobectomy. It is suggested that a percutaneous biliary endoprosthesis through the tumor should be avoided in patients in whom a possible curative resection can be considered. External biliary drainage should only be performed in order to minimize the manipuIation of the tumor in such patients.

EUS-cholangio-drainage of the bile duct: report of 4 cases

BACKGROUND: Endoscopic retrograde cholangiography with stent insertion is an established procedure for palliation of patients with malignant pancreaticobiliary strictures. In some patients, however, placement of a stent by means of a duodenoscope is not possible. Percutaneous transhepatic biliary drainage is an alternative method that has a complication rate of up to 15%. Four cases of successful EUS-guided-cholangio-drainage are presented in which the major papilla could not be cannulated at endoscopic retrograde cholangiography. METHODS: For puncture of the intrahepatic or extrahepatic bile duct, a modification of the one-step technique for the drainage of pancreatic pseudocysts was used. RESULTS: Stent insertion was successful in 3 of the 4 patients. In these 3 patients cholestasis resolved promptly. CONCLUSIONS: EUS-guided cholangio-drainage is a potential alternative to percutaneous transhepatic biliary drainage and endoscopic retrograde cholangiography in the therapy of malignant pancreaticobiliary strictures, especially in patients who have undergone gastrectomy or partial gastrectomy with Billroth II reconstruction.     

Pathophysiologic mechanisms in patients with cholangitis or obstructive jaundice: Results of a cholangiographic study

Bacterial reflux from the biliary tract to the systemic circulation is considered to be the primary etiologic factor in bacteremia and the development of sepsis. However, as the pathophysiologic features of the biliary tract that may promote such a reflux of biliary bacteria remain unclear, we investigated, using direct cholangiography, the pathophysiologic relationship between the intrahepatic bile ducts and biliary reflux into the systemic circulation after the percutaneous infusion of a contrast material containing indocyanine green (ICG) into the circulating blood. The subjects were 19 patients who underwent percutaneous transhepatic cholangiography with drainage to treat either a biliary infection or obstructive jaundice, an 8 post-T-tube control patients with normal biliary drainage. The relationship between the biliary tract pressure and ICG reflux during cholangiography was also analyzed. An ICG reflux was observed in all 19 patients who had undergone percutaneous transhepatic cholangiography with drainage and in 2 of the 8 control patients. In all patients who showed positive ICG reflux, this occurred when the biliary pressure increased to 25cm H₂O. An ICG reflux was seen in the 16 patients with a positive bile culture, and in 7 of 13 patients with a negative bile culture. When we analyzed ICG reflux in relation to the morphology of the intrahepatic bile duct, we found that all 4 patients who had cholangitic hepatic abscesses also exhibited higher ICG reflux concentrations and the clinical symptoms of cholangitis. Radiologically, all 7 patients with cholangitis demonstrated many small intrahepatic branches, and they exhibited moderate ICG refluxes, whereas the 6 patients who had obstructive jaundice but no cholangitis had fewer ICG refluxes and no clinical symptoms. This study demonstrated two possible pathophysiological routes for biliary reflux: (1) via cholangitic hepatic abscesses, with entry of the bacteria directly into the circulating blood, or (2) via the small intrahepatic biliary branches, in which entry of bacteria into the systemic circulation occurs through the cholangioles.     

Resection of intrahepatic bile duct carcinoma with hilar bile duct and portal vein invasion--a case report

A case of resected intrahepatic bile duct cancer with hilar bile duct and portal vein invasion is presented. Percutaneous transhepatic biliary drainage was performed to alleviate jaundice and evaluate the biliary system. Intraductal tumor extension was determined, and an accurate histological diagnosis was made in biopsy material obtained under percutaneous transhepatic cholangioscopy. Preoperative surgical planning was carried out on the basis of an evaluation of the findings of ultrasonography, computed tomography, arteriography, portography and percutaneous transhepatic cholangioscopy. Curative surgery, which included right hepatic lobectomy with total caudate lobectomy and combined resection and reconstruction of the portal vein, was performed. Bilioenteric continuity was re-established by a Roux-en-Y jejunal loop. The histological diagnosis was moderately differentiated tubular adenocarcinoma originated in the right posterior branch of the intrahepatic bile duct. Postoperative recovery was very good, and the patient has now been enjoying a good active social life for the past three years with no signs of tumor recurrence. This case report discusses the accurate diagnosis and rational surgical treatment for intrahepatic bile duct carcinoma with hilar invasion.     

A new therapeutic trial of secretin in the treatment of intrahepatic cholestasis

Many animal experiments have been studied on the choleretic effects of secretin. We intended to estimate secretin choleresis in human (15 patients) who had received PTCD or T-tube insertion into the common bile duct. Based upon these data of secretin and choleresis, secretin was administered to 11 patients with prolonged jaundice due to intrahepatic cholestasis in order to evaluate this as a new therapy for intrahepatic jaundice. As controls, eleven patients with intrahepatic cholestasis treated with steroid hormones and/or phenobarbital were used. In all cases with biliary drainage, secretin produced a remarkable choleretic effect with a high concentration of bicarbonate. In 9 out of 11 patients with intrahepatic cholestasis who were treated with secretin, levels of serum bilirubin decreased linearly and other liver function tests returned to the normal range. The mean values of T^1/2 (number of days required for reduction by half) of serum bilirubin in 9 effective cases to secretin was 10.8 days. On the other hand, that in 11 effective cases treated with steroid hormones and/or phenobarbital was 23.2 days. These results suggest that secretin therapy may be an effective treatment for intrahepatic cholestasis.     

Cholestatic liver diseases: slow progress in understanding and treating slowly progressive disorders

BACKGROUND: Cholestatic liver diseases are characterized by failure of normal amounts of physiological bile to reach the gastrointestinal tract. Any interference with normal bile flow from the canalicular membrane of the hepatocyte to the distal common bile duct may result in cholestasis. METHODS: Literature review. RESULTS: In primary biliary cirrhosis (PBC), the small intrahepatic bile ducts are destructed, resulting in obstruction of intrahepatic bile flow, whereas extrahepatic and/or intrahepatic biliary strictures block the passage of bile towards the intestine in primary sclerosing cholangitis (PSC). In contrast, the biliary tree is morphologically unaffected in less common cholestatic liver diseases as benign recurrent intrahepatic cholestasis (BRIC) and progressive familiar intrahepatic cholestasis (PFIC1-4). Genetic defects in hepatic canalicular transport mechanisms and bile salt synthesis deficiencies seem to underlie these types of cholestatic disorders. CONCLUSION: Recent advances in understanding and treatment of cholestatic liver diseases may help in better diagnosing and treating the various conditions characterized by cholestasis.     

Biloma following repeated transcatheter arterial embolization and complicated by intrahepatic duct stones: A case report

Biloma is an encapsulated bile collection outside the biliary tree due to a bile leak. It is occasionally found following traumatic liver injury or iatrogenic injury to the biliary tract, induced either during an endoscopic or surgical procedure. It is a rare complication of transcatheter arterial embolization (TAE). Although biloma can be shrunk by appropriate aspiration or drainage in majority of cases,we report a case of intrahepatic biloma following repeated TAE for hepatocellular carcinoma (HCC) and complicated by infection and intrahepatic stones. This particular constellation of problems has not been reported before and the intrahepatic stones need to be removed by percutaneous procedure.     

Biliary tuberculosis causing cicatricial stenosis after oral anti-tuberculosis therapy

A 36-year-old Philippine woman presented with dark urine and yellow sclera. Endoscopic retrograde cholangiopancreatography (ERCP) confirmed dilatation of the intrahepatic bile ducts and also showed an irregular stricture of the common hepatic duct at the liver hilum. Histological examination of biopsies from the bile duct revealed epithelioid cell granulomas and caseous necrosis. Tubercle bacilli were then detected on polymerase chain reaction (PCR) testing of the bile, giving the diagnosis of biliary tuberculosis. Although microbiological cure was confirmed, the patient developed cicatricial stenosis of the hepatic duct. She underwent repeated treatments with endoscopic biliary drainage (EBD) tubes and percutaneous transhepatic biliary drainage (PTBD) tubes, and the stenosis was corrected after 6 years. We present a case of tuberculous biliary stricture, a condition that requires careful differentiation from the more common malignancies and needs long-term follow-up due to the risk of posttreatment cicatricial stenosis, although it is rare.
