Fifteen patients with cholestatic disorders were treated for 1 to 5 months with phenobarbital. Primary biliary cirrhosis was diagnosed in seven, sclerosing cholangitis in two, intrahepatic biliary hypoplasia in three, and cholestatic hepatitis in three. Except for the patients with cholestatic hepatitis, in whom marked cholestasis was virtually the only abnormality in liver biopsy specimens, serum bilirubin and bile acid concentrations were diminished during therapy, the hepatic clearance of sulfobromophthalein and 131-I-rose bengal was variably enhanced, and there was relief from pruritus. Serum cholesterol concentrations and other measures of hepatic function were not significantly changed during therapy except for serum alkaline phosphatase activity, which rose in twelve patients. Parallel changes occurred in 5'-nucleotidase, suggesting a hepatic origin for the alkaline phosphatase activity. These studies indicate that phenobarbital therapy is associated with improvement in organic anion clearance in some patients with cholestatic disorders and may be beneficial to such patients.

Selective hepatic arteriography and umbilical portography in a patient with idiopathic sclerosing cholangitis revealed uneven distribution of blood flow through the liver, the majority of the contrast media being demonstrated in the central portions of the liver. Mild portal hypertension was present. The stenotic biliary tree offered no unusual resistance to the passage of dye from the main biliary radicals into the duodenum. T tube drainage dramatically relieved pruritus, but clinical improvement with weight gain, disappearance of jaundice and reduction of portal pressure did not occur until after the administration of steroids. After one year of steroid therapy, liver biopsy showed a reduction in the periportal inflammatory reaction and lessening of the diffuse stenosis of the biliary tree. The relationship of these findings to current pathophysiologic hypotheses concerning sclerosing cholangitis is discussed.

The development of the syndrome of chronic intrahepatic cholestasis in five young, black men who had systemic granulomatous disease and clinical features consistent with those of sarcoidosis is described. Clinical and biochemical aspects, similar to those of primary biliary cirrhosis, included pruritus, jaundice, hepatomegaly and striking elevations of serum levels of alkaline phosphatase and cholesterol. (One patient had skin xanthomas.) Mitochondrial antibodies were not found; and survival of the patients (7 to 18 years) exceeded the usual survival of patients with primary biliary cirrhosis. The histologic abnormalities included noncaseating granulomas, chronic intrahepatic cholestasis, increased copper in hepatocytes, progressive diminution in number of interiobular bile ducts, periportal fibrosis and the eventual development of a micronodular "biliary" cirrhosis. The histologic evolution of the disease suggests a slow, progressive destruction of the bile ducts by granulomas. Although the end stage of this syndrome resembles primary biliary cirrhosis, the characteristic nonsuppurative, destructive cholangitis of primary biliary cirrhosis was not present.

Despite reports to the contrary, unobstructed drainage of 50% of an otherwise normal liver through either the right or left uninfected hepatic duct is adequate to restore normal liver function, even if the obstructed lobe remains in place. An undrained liver lobe, if present, may require no further treatment. As long as it is completely obstructed and uninfected, it will undergo a progressive asymptomatic atrophy. Cholangitis invariably develops behind a partial lobar ductal obstruction, producing jaundice, pruritus, and fever. Unless unobstructed, uninfected biliary flow can be achieved through a segmental or lobar duct, it is better that the duct be completely obstructed and the affected liver parenchyma allowed to atrophy, provided there is normal biliary flow from the residual 50% of liver. This concept is important in the management of injured anomalous segmental or lobar hepatic duct and in the palliative treatment of bile duct carcinoma. Localized intrahepatic infections communicating with abnormal biliary ducts will require hepatic resection of the infected parenchyma and ducts for cure. The abnormality may be saccular dilatation of the intrahepatic ductal system with abscess formation or intrahepatic abscess associated with stenosis of the ductal system from trauma to the duct, to the duct and liver, or to retained intrahepatic stones. Diffusely situated intrahepatic abscesses secondary to ductal abnormalities can be treated with systemic antibiotics, local drainage of a dmoninant abscess, and efforts to improve biliary drainage.

In a 40-year-old patient unexplained recurrent attacks of epigastric colic with transient cholestatic icterus occurred over a 9-year period. When the patient was again hospitalised because of progressive pain-free icterus associated with mild pruritus (alkaline phosphatase 900 U/l, direct bilirubin 305 mumol/l, GOT 187 U/l, GPT 103 U/l) sonography revealed liver enlargement to 17 cm, extended intrahepatic bile ducts and an echodense area of about 1 cm size in the region of the bifurcation of the common hepatic duct. Fine-needle puncture did not yield clear cytological findings. Endoscopic retrograde cholangiopancreatography pointed to sclerosing cholangitis. This diagnosis was confirmed by liver punch biopsy. Since the patient did not agree to a liver transplantation, he was treated with 450 mg ursodeoxycholic acid twice daily, resulting in marked reduction of the liver parameters until severe cholangiosepsis and acute renal failure occurred about 4 months later. The septic condition and its complications could not be managed despite thorough intensive-care measures so that a liver transplant had to be performed after all. Histology of the explantate revealed a cholangiocarcinoma in the region of the bifurcation of the common hepatic duct. At first the patient's condition improved markedly but one and half months later the transplant was rejected and the patient died.

Patients with primary sclerosing cholangitis are at an increased risk of developing cholangiocarcinoma, which is difficult to diagnose because the biliary tree is already distorted. Eleven patients with primary sclerosing cholangitis who underwent orthotopic liver transplantation at this hospital were evaluated. Four patients had coincidental histologically proved cholangiocarcinoma. Patients with cholangiocarcinoma in contrast to patients without tumour presented with rapid onset of persistent jaundice, pruritus, and weight loss associated with an appreciable rise in bilirubin (8x v 2x) and alkaline phosphatase (3.5x v 1.2x) over one year. Cholangiography and computed tomography showed appreciably dilated intrahepatic bile ducts (3/4 v 0/7). The diagnosis of cholangiocarcinoma could only be established before operation in one patient by fine needle aspiration cytology. Tumour was recognised at operation in one other. Histological examination of hepatectomy specimens showed that patients with cholangiocarcinoma had less advanced histological features of primary sclerosing cholangitis. Multiple areas of carcinoembryonic antigen positive epithelial atypia and carcinoma in situ were found in all patients with cholangiocarcinoma. Cholangiocarcinoma recurred in two patients at 14 and 39 months after transplantation. Superimposed cholangiocarcinoma can be predicted in most patients with cholangitis before transplantation, although a definitive diagnosis is difficult to make. Their prognosis after successful transplantation is guarded.

Fifty-three patients with biliary obstruction caused by unresectable malignancy were treated by attempted insertion of an endoprosthesis by the percutaneous-endoscopic route. This was successful in 50 patients. A single endoprosthesis was inserted in each case. Both right and left hepatic duct decompression were obtained in 31 patients, but only unilateral or segmental drainage was achieved in 19 patients. Procedure-related complications occurred in 18 (36%) patients, and 15 (30%) patients died within 30 days of the procedure. Satisfactory resolution of jaundice was obtained in 26 (84%) patients with bilateral decompression and in 12 (63%) of those with unilateral drainage. The 30-day mortality rate was 26% for patients with bilateral and 37% for those with unilateral drainage. The morbidity rate from cholangitis after endoprosthesis insertion was 10% after bilateral and 32% after unilateral drainage. None of these differences was statistically significant. Surviving patients with satisfactory bile drainage were relieved of symptoms such as pruritus. The combined percutaneous-endoscopic technique enables difficult biliary strictures to be intubated. Although bilateral duct drainage is preferable, the palliation is often worthwhile even when segmental ducts alone are drained.

The use of ultrasound-guided PTCD in 49 patients with hilar cholangiocarcinoma was evaluated. In 11 patients PTCD was performed as a preoperative measure either to outline tumor extension or to treat cholangitis. Postoperatively, the catheters were used to stent bilioenteric anastomoses and served to guide iridium wires for radiotherapy in nine patients with nonresectable tumor or tumor residue after resection. In 20 inoperable patients with tumor diameter smaller than 3 cm and in whom at least one catheter could be manipulated through the tumor, PTCD was combined with internal and external radiotherapy. The remaining 18 patients were palliated with PTCD only. In 29 patients (59%) complete drainage of the biliary system was achieved. Twenty-seven of these had complete internal drainage using endoprostheses. Two had a combination of an endoprosthesis and external catheter drainage. Of the 20 patients (41%) with incomplete drainage, 12 had endoprostheses, four had a catheter and an endoprosthesis, and in the remaining four external catheter drainage was the optimum result. PTCD was successful in treating eight of ten patients with cholangitis and 12 of 16 patients with pruritus. Procedure-related complication occurred in 11 patients (22%). With the exception of one, all complications could be classified as minor, requiring only conservative measures. A major complication was seen in a patient with ascitic fluid and severe cholangitis. PTCD caused a bacterial peritonitis, of which the patient died. The median survival of patients treated with PTCD alone only was 4 months. A significant increase in survival was noted in patients treated with PTCD and radiotherapy (median survival 8 months).(ABSTRACT TRUNCATED AT 250 WORDS)

Initial symptoms in a hitherto healthy 23-year-old man were jaundice (bilirubin 21.7 mg/dl) and pruritus, but extensive radiological, endoscopical, microbiological and laboratory investigations failed to reveal the cause. Stool culture positive for Salmonella agona suggested intrahepatic cholestasis resulting from a Salmonella cholangitis. However, antibiotic treatment was not successful. As he was in generally good health the patient declined further investigations. He returned two years later because of fatigue, lack of appetite and weight loss. Further tests now revealed lymphogranulomatosis in stage IVb of the nodular sclerosing type. The case demonstrates that cholestasis as an isolated early symptom of Hodgkin's disease can precede by years any further signs of the disease.

The palliative therapy of stenoses of the biliary tract is a difficult choice. Because percutaneous or endoscopic drainage methods are fraught with complications, an endoprosthesis for surgical intubation of the biliary tract has been developed. Thirty patients were treated by this method. After choledochotomy, the endoprosthesis is positioned surgically above the sphincter of Oddi, thereby avoiding ascending cholangitis. Twenty-nine patients (13 with gallbladder cancer, 11 with cholangiocarcinomas, 5 with metastases) presented with neoplastic compression, and one patient had an early postoperative stricture with loss of substance after right hepatectomy for hepatic metastases. The operative mortality was 3.3% (one pulmonary complication). Resolution of jaundice was obtained in all but two patients, and pruritus always resolved. The mean survival time for the patients with cholangiocarcinoma was 12.2 months and 6.33 months for those with gallbladder cancer. Indices of satisfaction (Bismuth's method) were 71% (gallbladder cancer), 93.5% (hilar cholangiocarcinoma), and 92% (metastatic compressions). This new type of surgical endoprosthesis is an alternative in the palliative treatment of neoplastic hilar compression because it is well tolerated, has a low rate of operative mortality or morbidity, and affords an acceptable quality of life for the patients.
