Impact of Genotype, Serum Bile Acids, and Surgical Biliary Diversion on Native Liver Survival in FIC1 Deficiency. Hepatology 2021; 74:892-906. [PMID: 33666275 PMCID: PMC8456904 DOI: 10.1002/hep.31787] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2020] [Revised: 01/17/2021] [Accepted: 01/27/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND AND AIMS Mutations in ATPase phospholipid transporting 8B1 (ATP8B1) can lead to familial intrahepatic cholestasis type 1 (FIC1) deficiency, or progressive familial intrahepatic cholestasis type 1. The rarity of FIC1 deficiency has largely prevented a detailed analysis of its natural history, effects of predicted protein truncating mutations (PPTMs), and possible associations of serum bile acid (sBA) concentrations and surgical biliary diversion (SBD) with long-term outcome. We aimed to provide insights by using the largest genetically defined cohort of patients with FIC1 deficiency to date. APPROACH AND RESULTS This multicenter, combined retrospective and prospective study included 130 patients with compound heterozygous or homozygous predicted pathogenic ATP8B1 variants. Patients were categorized according to the number of PPTMs (i.e., splice site, frameshift due to deletion or insertion, nonsense, duplication), FIC1-A (n = 67; no PPTMs), FIC1-B (n = 29; one PPTM), or FIC1-C (n = 34; two PPTMs). Survival analysis showed an overall native liver survival (NLS) of 44% at age 18 years. NLS was comparable among FIC1-A, FIC1-B, and FIC1-C (% NLS at age 10 years: 67%, 41%, and 59%, respectively; P = 0.12), despite FIC1-C undergoing SBD less often (% SBD at age 10 years: 65%, 57%, and 45%, respectively; P = 0.03). sBAs at presentation were negatively associated with NLS (NLS at age 10 years, sBAs < 194 µmol/L: 49% vs. sBAs ≥ 194 µmol/L: 15%; P = 0.03). SBD decreased sBAs (230 [125-282] to 74 [11-177] μmol/L; P = 0.005). SBD (HR 0.55, 95% CI 0.28-1.03, P = 0.06) and post-SBD sBA concentrations < 65 μmol/L (P = 0.05) tended to be associated with improved NLS. CONCLUSIONS Less than half of patients with FIC1 deficiency reach adulthood with native liver. The number of PPTMs did not associate with the natural history or prognosis of FIC1 deficiency. sBA concentrations at initial presentation and after SBD provide limited prognostic information on long-term NLS.

Abstract
Objectives To determine the safety and feasibility of intraductal radiofrequency ablation (RFA) followed by locoregional tumor treatments in patients with non-resectable malignant biliary obstruction and stent re-occlusion. Methods Fourteen patients with malignant biliary obstruction and blocked metal stents were studied retrospectively. All had intraductal RFA followed by locoregional tumor treatments and were monitored clinically and radiologically. The practicality, safety, postoperative complications, jaundice remission, stent patency and survival time were analyzed. Results Combination treatment was successful for all patients. There were no severe complications during RFA or local treatments. All patients had stent patency restored, with a decline in serum bilirubin. Three patients had recurrent jaundice by 195, 237 and 357 days; two patients underwent repeat intraductal RFA; and one required an internal-external biliary drain. The average stent patency time was 234 days (range 187-544 days). With a median follow-up of 384 days (range 187-544 days), six patients were alive, while eight had died. There was no mortality at 30 days. The 3, 6, 12 and 18 month survival rates were 100%, 100%, 64.3% and 42.9%, respectively. Conclusion Intraductal RFA followed by locoregional tumor treatments for occluded metal stents is safe and practically feasible and potential increase stent patency and survival times.

Abstract
Hepatic sarcoidosis is a rare indication for liver transplantation. Using the United Network for Organ Sharing (UNOS)/Organ Procurement and Transplantation Network (OPTN) database, we evaluated patient and graft survival after orthotopic liver transplantation for sarcoidosis between October 1987 and December 2007. We assessed the potential prognostic value of multiple demographic and clinical variables, and we also compared these patients to a case-matched group of patients with primary sclerosing cholangitis (PSC) or primary biliary cirrhosis (PBC). The 1- and 5-year survival rates for the sarcoidosis group were 78% and 61%, respectively, and these rates were significantly worse than the rates for the PSC/PBC group (P = 0.001). Disease recurrence in the liver is a rare cause of graft loss or patient death. Three deaths occurred in the sarcoidosis group because of recurrent hepatic sarcoidosis, and 1 death was a result of cardiac sarcoidosis. A univariate analysis identified an increasing donor risk index as a significant negative factor for outcomes for the sarcoidosis group [hazard ratio (HR) = 2.06, confidence interval (CI) = 1.04-4.06, P = 0.037], but this finding was not found in a multivariate analysis, in which no independent predictors were found to have a significant impact. A case-matched univariate analysis demonstrated that sarcoidosis and morbid obesity were significant negative factors for outcomes, and in a multivariate analysis, sarcoidosis continued to predict worse outcomes (HR = 2.39, CI = 1.21-4.73, P = 0.012). In conclusion, an analysis of the UNOS/OPTN database indicates that the patient and allograft survival rates for hepatic sarcoidosis are satisfactory, but they are worse in comparison with the rates for other cholestatic liver diseases.

Abstract
The aim of this study is to evaluate the incidence, etiology, and risk facrors for prolonged severe intrahepatic cholestasis (PSIC) after 129 pediatric living-donor liver transplantations (LDLT). The incidence of PSIC was 25.6% (n = 33). Twenty-eight (84.8%) versus 5 (15.2%) children experienced early versus late PSIC, respectively. Among these 33 children with PSIC, 8 (24.2%) received a donor liver with mild to moderate fatty change, 4 (12.1%) with low graft-body weight ratios, and 4 (12.1%) with ABO incompatibility. The predominant etiologies were acute rejection (n = 15; 45.5%), chronic rejection (n = 6; 18.2%), virus (n = 3; 9.1%), vascular complications (n = 4; 12.1%), and initial graft dysfunction (n = 10; 30.3%). ABO incompatibility (P = .032; odds ratio [OR] 3.25), chronic rejection (P = .012; OR 4.76), and vascular complications (P = .046; OR 1.82) were significant variables associated with PSIC. Donor selection with ABO compatibility as well as early detection and management of chronic rejection and vascular complications may be important to prevet PSIC in LDLT.

Abstract
INTRODUCTION Little is known about the epidemiology, causes and outcomes of neonatal cholestasis in the Asian population beyond Japan and Taiwan. METHODS This was a prospective, observational study on patients with neonatal cholestasis who were referred to the University of Malaya Medical Centre, Malaysia, between November 1996 and May 2004. RESULTS Biliary atresia (BA) (29 percent) and idiopathic neonatal hepatitis (38 percent) were the two commonest causes of neonatal cholestasis (n is 146) that were referred. Out of the 39 patients (27 percent of the total) who died at the time of review, 35 succumbed to end-stage liver disease. Three of the four patients (three BA, one progressive familial intrahepatic cholestasis [PFIC]) who had a living-related liver transplant (LT) died after the surgery (two BA, one PFIC). Six (four percent) of the remaining 107 survivors had liver cirrhosis. The overall four-year survival rates for patients with native liver and LT as well as those with native liver alone for all cases of neonatal cholestasis were 72 percent and 73 percent, respectively, while the respective survival rates for BA were 38 percent and 36 percent. CONCLUSION BA and idiopathic neonatal hepatitis are important causes of neonatal cholestasis in Malaysian infants. In Malaysia, the survival rate of patients with neonatal cholestasis, especially BA, is adversely affected by the lack of a timely LT.

Abstract
UNLABELLED Bile salt export pump (BSEP; ATP-binding cassette, subfamily B, member 11) mutations in humans result in progressive familial intrahepatic cholestasis type 2, a fatal liver disease with greatly reduced bile flow. However in mice, Bsep knockout leads only to mild cholestasis with substantial bile flow and up-regulated P-glycoprotein genes (multidrug resistance protein 1a [Mdr1a] and Mdr1b). To determine whether P-glycoprotein is responsible for the relatively mild phenotype observed in Bsep knockout mice, we have crossed mouse strains knocked out for Bsep and the two P-glycoprotein genes and generated a triple knockout mouse. We found that a knockout of the three genes leads to a significantly more severe phenotype with impaired bile formation, jaundice, flaccid gallbladder, and increased mortality. The triple knockout mouse is the most severe genetic model of intrahepatic cholestasis yet developed. CONCLUSION P-glycoprotein functions as a critical compensatory mechanism, which reduces the severity of cholestasis in Bsep knockout mice.

Abstract
BACKGROUND Hodgkin lymphoma (HL)-related vanishing bile duct syndrome (VBDS) and idiopathic cholestasis (IC) are rare conditions that often lead to liver failure and death. The available literature consists primarily of case reports, resulting in little clarity as to the clinical course and ideal treatment for this disease. MATERIAL AND METHODS We performed a literature search from which we identified all published cases of HL-related VBDS or IC, and created a database of detailed presentation, treatment, and outcome information for all patients. Patient and disease factors were analyzed for an association with overall survival and liver failure-free survival. A case presentation introduces this analysis. RESULTS Thirty-seven cases of HL-related VBDS/IC were identified. Median follow-up was 7 months; 1-year OS and liver failure-free survival (LFFS) are 43% and 41%, respectively. Sixty-five percent of the patients died while 30% were alive with normal or near-normal stable liver function and no evidence of recurrent HL at last evaluation. Of the 20 patients without residual HL following therapy, 12 (60%) achieved liver failure-free survival. On univariate analysis, factors significantly associated with improved liver failure-free survival were stage I/II HL (p=0.02), a complete response of HL (p=0.0002), and delivery of radiotherapy (pB0.0001). Two patients received chemotherapy without radiation and survived with recovery of liver function. DISCUSSION HL-related VBDS/IC is potentially reversible and not uniformly fatal, with 30% of presenting patients demonstrating good lymphoma and liver outcomes after definitive therapy for HL. As a complete response of HL provides the only possibility of recovering liver function, patients with this disease should proceed to definitive treatment of HL as soon as feasible.

Abstract
Recent advances in genetics and in physiopathology of bile composition and excretion have clarified the understanding of progressive familial intrahepatic cholestasis (PFIC). The aim of the present study is to review the experience of our center in terms of diagnosis, management and outcome of 49 pediatric PFIC patients, belonging to the three classical subtypes described. We analyse the clinical, biological, and histological patterns and review the response to the medical and surgical treatment and the global outcome. The only clinical difference between the different subtypes of PFIC patients was the intensity of pruritus. Serum gamma-glutamyltransferase (GGT) and liver histology allowed to differentiate PFIC III from PFIC I and II patients. High levels of biliary bile acids in 2 low-GGT patients was associated with favourable outcome. Response to ursodeoxycholic acid (UDCA) varies from patient to patient and was not associated to a particular subtype of PFIC. In five patients of this cohort, external biliary diversion was performed without improvement. Transplantation is indicated whenever medical treatment fails to restore normal social life, growth and well being of the child and it is associated with excellent survival (> 90%).

Abstract
Progressive familial intrahepatic cholestasis (PFIC) is a heterogenous group of disorders with various etiologies. Recent molecular and genetic studies have categorized the spectrum of types. Liver transplantation is a curative modality of treatment in this disease. We report our experience with 13 patients with PFIC who underwent living related liver transplantation. The follow-up periods ranged from 12 to 50 months. Two children died at 1 and 2 years posttransplantation, leading to a decrease in survival rate from 100% in the first year to 84.6%.

Abstract
BACKGROUND The aim of this study was to determine whether patency rates differ with respect to the material, design, and surface texture of 3 different plastic stents. METHODS A total of 120 patients (median age 70.5 years; interquartile range 62-78 years) with malignant mid or distal bile duct strictures, seen between March 1996 and May 1999, were prospectively randomized to receive a 10F polyurethane stent, a Teflon Tannenbaum stent, or a hydrophilic hydromer-coated polyurethane stent. The primary study outcome measure was the interval between stent insertion and the first episode of clogging (or the presence of jaundice at death without stent exchange). All 3 types of stent were studied by scanning electron microscopy before insertion. RESULTS A total of 19 patients were excluded from long-term follow-up. Median duration of stent patency was 76 days overall (interquartile range 29-150 days) and 76 (interquartile range 30-110) days for hydrophilic hydromer-coated polyurethane, 108 (interquartile range 33-186) days for 10F polyurethane, and 58 (interquartile range 21-188) days for Teflon Tannenbaum stents. There were no statistically significant differences among stent types. The hydrophilic hydromer-coated stent had the smoothest surface, as visualized by scanning electron microscopy. CONCLUSIONS No significant differences in the patency of 3 types of stents were detected in this randomized trial. In particular, the hydrophilic hydromer-coated plastic stent did not provide clinical advantages despite its smooth surface.

Abstract
BACKGROUND/AIMS Hilar bile duct cancer progresses slowly but easily invades the nearby portal vein or hepatic artery. Thus, in some cases, curative resection is impossible, so we need to determine the best non-surgical treatments for this tumor. METHODOLOGY We classified 98 patients with hilar bile duct cancer into 3 categories: a non-surgical group (34 cases), an exploratory laparotomy group (9 cases), and a surgical resection group (55 cases). Survival rates were examined in the light of clinical factors. RESULTS In the non-surgical group, extensive vessel invasion was the most common reason for unresectability (13 cases), with broad biliary extension the second most common (11 cases). In the exploratory laparotomy group the most common reason for unresectability was severe vessel invasion (6 cases). Cumulative 1- and 2-year survival rates for patients with unresectable tumors without distant metastasis were 26.9% and 7.2%, respectively. One- and 2-year survival rates for patients with unresectable tumors and with total bilirubin of less than 2 mg/dL on discharge were 36.8% and 9.8%, respectively. The 1-year survival rate with placement of an expandable metallic stent was as high as 55.6%; without the stent it was 7.1% (P = 0.005). Radiation therapy gave a better prognosis than did no radiation (P = 0.01). CONCLUSIONS Portal and arterial invasion were the principal reasons for unresectability. Use of an expandable metallic stent or radiation therapy, and a total bilirubin level of less than 2 mg/dL on discharge, were factors that enhanced survival in unresectable cases, but distant metastasis, dissemination, and poor general condition or liver function were negative factors for survival.

Abstract
BACKGROUND The systematic use of metal stents to treat biliary obstruction is restricted by high cost compared with plastic stents. The aims of this study were to compare cost and efficacy of plastic stents and metal stents in the treatment of patients with malignant common bile duct strictures and to define factors that predict survival of these patients. METHODS One hundred eighteen patients (mean age 75 years) with malignant strictures of the common bile duct were randomized to placement of a plastic stent or metal stent. Comparisons were made with the Mann-Whitney or chi-square test as indicated; survival rates were compared with a Cox proportional hazards model. RESULTS There was no significant difference in survival between the two groups. Time to first obstruction was longer for patients in the metal stent group (metal stent, median not reached vs. plastic stent, 5 months; p = 0.007). The number of additional days of hospitalization, days of antibiotic therapy, and the numbers of ERCPs and transabdominal US procedures was significantly higher in the plastic stent group. After multivariate analysis, only the presence of liver metastases was independently related to survival (p < 0.0005; OR = 2.25). This variable defined a group with a shorter survival. Median survival of patients with hepatic metastasis at diagnosis was 2.7 months compared with 5.3 months for patients without liver metastasis; in the latter group, the overall cost associated with metal stents was lower than for plastic stents. CONCLUSIONS Metal stent placement is the most effective treatment of inoperable malignant common bile duct stricture. Placement of a metal stent is cost effective in patients without hepatic metastases, whereas a plastic stent should be placed in patients with spread of the tumor to the liver.

Abstract
BACKGROUND/AIMS Acute serious liver disease which is unrelated to infectious, obstructive, or metabolic disease is uncommon. Many drugs have been implicated. Data on its epidemiology are scarce. We performed a population-based prospective study of acute serious liver disease in Catalonia (Spain). METHODS A collaborating hospital network was set up. All patients with acute serious liver disease and negative viral hepatitis serological markers, without an obvious cause of liver disease, were included. RESULTS The incidence of acute serious liver disease was 7.4 per 10(6) inhabitants per year (95% CI; 6.0-8.8), which increased with age. The incidence of hepatocellular acute serious liver disease (3.84 per 10(6) per year) was greater than that of cholestatic and mixed patterns. The case-fatality ratio was 11.9% and mortality 0.8 per million person-years. The risk of death was similar among patients with hepatocellular and cholestatic patterns. Non-steroidal antiinflammatory drugs, analgesics, and antibacterials were the most frequently used drugs. CONCLUSIONS Acute serious liver disease which is unrelated to infectious, obstructive, or metabolic disease is rare. Its incidence increases with age. The prognosis of cholestatic acute serious liver disease does not significantly differ from that of the hepatocellular pattern. Non-steroidal antiinflammatory drugs, analgesics, and antibacterials were the most common drugs likely to be responsible for acute liver disease.

Abstract
GOALS To elucidate the natural progression of hepatolithiasis that showed no signs at the time of initial presentation. STUDY Over a 17-year period, we observed 122 of 311 patients with hepatolithiasis who reported no symptoms and, thus, who received no treatment at initial presentation. The follow-up period was for up to 15 years (mean, 10.08 years). RESULTS Fourteen of 112 patients (11.5%) developed some symptoms attributed to hepatolithiasis. The interval until the onset of symptoms ranged from 9 months to 7.33 years (mean, 3.42 years ). The developing symptoms included abdominal pain, hepatic abscess, cholangitis, and cholangiocarcinoma. Nine of the 14 patients (64.3%) developed stone migration to the extrahepatic bile duct at the onset of clinical symptoms. The incidence of lobar liver atrophy on computed tomography in the patients with symptomatic hepatolithiasis (13 of 14 patients; 92.9%) was significantly higher than that in the patients with asymptomatic hepatolithiasis (14 of 108 patients; 13.0%). The prognosis of the patients with symptomatic hepatolithiasis were as follows: 2 died of cholangiocarcinoma, 1 died of hepatic failure, and 11 survived. Fifteen of asymptomatic patients died, but none of these deaths were attributed to hepatolithiasis. CONCLUSIONS Close observation is an alternative management at initial presentation for patients with asymptomatic hepatolithiasis without extrahepatic stones or lobar liver atrophy.

Abstract
BACKGROUND/AIMS This study assesses the treatment of biliary obstruction in patients with hilar malignancies by metallic stents. METHODOLOGY Twenty-one consecutive patients with unresectable malignant biliary obstruction at the hepatic hilum (Bismuth type II, III and IV) were treated with percutaneous transhepatic placement of self-expandable metallic endoprostheses. The endoprostheses were successfully inserted in all patients. In 12 patients all segments of the liver were drained and in 9 patients partial segments of the liver were drained. RESULTS Seventeen patients (81%) showed relief from jaundice and could be freed of external drainage tubes. Ten patients (48%) showed no recurrent symptoms due to stent obstruction until death. Overall survival was 4.86+/-4.15 (mean+/-SD) months, stent patency was 3.76+/-3.64 months and comfort index representing a ratio of well-being was 70.5+/-38.3%. There was no significant difference in survival rate, stent patency or comfort index between the groups with complete and those with partial drainage. CONCLUSIONS Even in patients with complicated hepatic hilar biliary occlusions, internal drainage using metallic stents can relieve jaundice and leave patients free of external tubes with a comfortable quality of life.

Abstract
BACKGROUND Hepatic resection and percutaneous transhepatic cholangioscopic lithotomy (PTCSL) are the two main approaches to the treatment of hepatolithiasis, but comparisons of longterm followup results have not been adequately reported. STUDY DESIGN Of 86 patients with hepatolithiasis admitted to our institution between 1980 and 1996, we reviewed 54 patients: 26 who underwent hepatic resection and 28 who underwent PTCSL. Five patients who underwent postoperative cholangioscopic lithotomy were included in the former group. The remainder of the hepatolithiasis patients were not treated by hepatic resection or PTCSL and, therefore, were excluded from this study. Hepatic resections were mainly indicated for left-sided localized intrahepatic calculi, atrophic liver, and possible presence of cholangiocellular carcinoma. PTCSL was performed for right-sided, bilateral or recurrent stones at an average of 6 treatments (range 1 to 20 treatments) for each patient. There were no differences between the two groups in terms of gender or age. The recurrence rate of stones and longterm prognosis were analyzed using the Kaplan-Meier method, and other clinical factors listed below were statistically compared. RESULTS The rate of complete removal of stones was similarly high in each group (96.2% in the hepatic resection group versus 96.4% in the PTCSL group). The complication (38.5% versus 21.4%) and 5-year survival (85.6% versus 100%) rates were comparable. Remaining bile duct stricture (18.2% versus 60.9%, p < 0.01) and 5-year recurrence rates (5.6% versus 31.5%, p < 0.05) were statistically lower in the hepatic resection group than in the PTCSL group. CONCLUSIONS Hepatic resection, when combined with postoperative cholangioscopic lithotomy, is a preferable treatment for left-sided stones with strictures and bilateral stones.

Abstract
BACKGROUND/AIMS The authors aimed to study the importance of pre-operative jaundice reduction in the surgical treatment of icteric-type hepatoma (IHCC). METHODOLOGY A series of 10 patients with IHCC was reviewed. Eight out of the 10 patients underwent biliary drainage. Obstructive jaundice in the other 2 patients resolved spontaneously. Nine patients subsequently underwent transcatheter arterial embolization (TAE), which appeared to have an additional effect in reducing jaundice. RESULTS Consequently, 9 of the 10 patients achieved sufficient reduction of the jaundice preoperatively. After the evaluation of liver function, 8 patients underwent hepatectomy without any appreciable morbidity or mortality. The median survival time of the resected cases was 18 months. CONCLUSIONS A combination of biliary drainage and subsequent TAE is a recommended pre-operative strategy for the successful surgical treatment of IHCC.

Abstract
METHOD Thirty-five patients with malignant obstructive jaundice were given palliative treatment by percutaneous self-expandable metallic stents. Cholangiocarcinoma was the most frequent cause of biliary obstruction. The stricture was located in the hilum in more of 50% of cases. RESULTS Adequate biliary drainage was achieved in 97% of cases. Median survival was 182 days. 11% of patients have died within 30 days. Early complications occurred in 31% of patients. 25% of patients have shown recurrent jaundice after an average of 180 days. CONCLUSION Percutaneous self-expandable metallic stents are an efficient means treating malignant biliary strictures, particularly of upper biliary obstructions.

Abstract
We report the clinical and morphological features of an unusual hepatorenal disorder in 2 patients. The main clinical features were early onset of cholestatic liver disease and progressive tubulointerstitial nephritis, leading to renal death in early childhood. Renal histology showed interstitial fibrosis, tubular atrophy and dilatation, glomerular cysts in the cortex and periglomerular fibrosis; liver histology was characterized by portal fibrosis and bile duct abnormalities. Evaluating the 12 patients published in the literature, the long-term prognosis of the liver function appears bad, suggesting the possibility of a combined liver and kidney transplantation.

Abstract
Sickle cell intrahepatic cholestasis is a rare but potentially fatal complication of sickle cell disease. Its characteristic features include hepatomegaly, extreme total hyperbilirubinemia, coagulopathy, and acute liver failure. Although the pathophysiology is uncertain, most reports in the medical literature indicate that the prognosis is grim. The only effective therapy that has been reported in this setting is exchange transfusion. We describe two hemoglobin SS patients with sickle cell intrahepatic cholestasis. We conclude that exchange transfusion and supportive care aimed at correction of coagulopathy, stabilization of the acute liver disease, and perhaps most important, avoidance of surgical intervention are the keys to a successful outcome.

Abstract
Between 1987 and 1992 unilateral, segmental bilioenteric bypass-procedures (30 round ligament approach procedures, 4 peripheral bypass-procedures to the segment III bile duct and 3 to the segment V bile duct) were carried out in 37 icteric patients (twenty cholangio-carcinomas, 8 gallbladder-carcinomas, 6 other malignomas, 3 benign strictures). Postoperative complications were seen in 17 (46%) patients. The 30 day mortality rate was 3% (1/37). Relief of symptoms were achieved in 83% of patients. Objectively there was a significant postoperative reduction of serum bilirubin levels from mean 323 mumol/l to 109 mumol/(p < 0.005) and of the alkaline phosphatase from 708 U/l to 336 U/l (p < 0.005) respectively. This was achieved irrespectively of whether the segmental bypass was draining a segment only or the whole liver. Unilateral segmental bilioenteric bypass-procedures achieve an effective palliation in the majority of patients.

Abstract
PURPOSE The endoscopic treatment of malignant hilar obstruction is followed in 70% of the case by infection of undrained biliary sectors. We report the influence of complete biliary drainage on post procedural cholangitis. METHOD From January 1990 to January 1993 we treated 120 consecutive patients presenting with a malignant hilar obstruction. There were 61 women and 59 men, mean age 65 +/- 7.5 years. The level of stenosis was type II in 45 patients (37%), type III in 18 patients (13%) and above type III in 57 patients (48%). Complete biliary drainage with multiple biliary access was attempted in all patients. Long term internal drainage was achieved by metallic autoexpansive endoprosthesis. RESULTS Complete drainage was achieved in all patients with type II or type III biliary stenosis. Drainage was incomplete in all patients with biliary stenosis above type III. Early complications were observed in 35% of the patients. Persistent cholangitis, the most frequent complication (22%) was only observed in patients with above type III biliary stenosis. Mortality at 30 days was 17%. Recurrent biliary obstruction was observed in 22% of the patients after an average of 187 days. Median survival was 95 days. CONCLUSION Complete biliary drainage prevents persistent cholangitis in patients with type II or III biliary stenosis without increasing other complications related to biliary drainage.

Abstract
The article deals with experience in the treatment of 187 patients (in 1980-1992) with cicatricial stricture of the hepatic ducts in the region of their coalescence (0 stricture). A high cholecystoenteric anastomosis, was formed, on a transhepatic drain in 117 (group I) and a precision anastomosis in 70 patients (group II). Analysis of the results of the operations showed that in group I patients, the early postoperative period was quite severe with the development of specific complications due to use of a replaceable transhepatic drain (hematobilia, leakage of bile into the subdiaphragmatic space, subdiaphragmatic abscess). Ten patients died (8.5%), a recurrent stricture was encountered in 4 patients. In group II patients, the early postoperative period followed a favorable course, there were no fatal outcomes, only one patient had a recurrent stricture. Experience shows that a high precision cholecystoenteric anastomosis can be formed in cicatricial stricture of the hepatic ducts in the region of their coalescence by means of some methodical manipulations. However, it should not be considered an alternative to operations with framed drainage of the bile-draining anastomosis.

The effect of communication between the right and left liver on the outcome of surgical drainage for jaundice due to malignant obstruction at the hilus of the liver.

Abstract
Debate continues regarding the optimal management of irresectable malignant proximal biliary obstruction. Controversy exists concerning the ability of unilateral drainage to provide adequate biliary decompression with tumors that have occluded the communication between the right and left hepatic ductal systems. Between October 1986 and October 1989, 18 patients with malignant proximal biliary obstruction were treated by an intrahepatic biliary enteric bypass. Patients were divided into two groups based on the presence or absence of a communication between the right and left biliary systems. In Group I (n = 9), there was free communication; and in Group II (n = 9) there was no communication. There were two perioperative deaths (11%) one due to persistent cholangitis and the other to myocardial insufficiency both with one death in each group. The median survival (excluding perioperative deaths) was 5.6 months. Comparison of pre- and postoperative serum levels of bilirubin and alkaline phosphatase showed a significant decrease in each group, but no difference between the groups in the size of the reduction. Sixteen patients survived at least three months and the palliation was judged as excellent in eight, fair in five, and unchanged in three. These results demonstrate the effectiveness of biliary enteric bypass regardless of communication between the left and right biliary ductal systems.

Prior esophageal variceal bleeding does not adversely affect survival after orthotopic liver transplantation. Hepatology 1993; 18:66-72.

Abstract
Prior variceal bleeding may adversely affect the prognosis of orthotopic liver transplantation. We studied this question by evaluating all 175 adult patients undergoing orthotopic liver transplantation at our institution to determine risk factors associated with mortality after transplantation. Seventy patients demonstrated prior variceal bleeding, and of those, 32 had a course of sclerotherapy. Thirteen also had portal systemic shunts. Compared with the 105 transplant patients who had no prior bleeding, patients who bled were more likely to have parenchymal liver disease (74% vs. 50%), equally likely to have cholestatic liver disease (19%), and less likely to have malignancy (6% vs. 19%) or fulminant liver failure (1% vs. 12%). Bleeding patients also were more likely to be Child-Pugh class C (46% vs. 35%). By the common closing date of December 31, 1990, 26 patients (37%) with prior bleeding and 48 patients (46%) without bleeding died after transplantation. From survival curves, patients with prior bleeding had improved survival rates at 1 yr (65% vs. 54%), at 3 yr (60% vs. 47%) and at 5 yr (55% vs. 43%), although the differences were not statistically significant. With a proportional hazards model to adjust for confounding effects, the relative risk of mortality among patients with prior bleeding was 0.60 (95% confidence interval, 0.27 to 1.30). Sclerotherapy or portal systemic shunts did not alter survival. Important adverse risk factors for mortality included older age at transplantation, black race, malignant disease and more advanced Child-Pugh class. This study suggests that prior esophageal variceal bleeding did not adversely affect the mortality of patients undergoing orthotopic liver transplantation.

Abstract
Tissue cholestasis is a histologic feature in some patients with alcoholic liver disease, but its significance is unknown. We studied prospectively the clinical, laboratory, and histologic findings of 306 chronic male alcoholics in whom liver tissue was available. Tissue cholestasis permitted identification of two groups: group I, absent or mild cholestasis (239 patients), and group II, moderate to severe cholestasis (67 patients). Statistical evaluation was performed by Student's t test and regression analyses. In patients with tissue cholestasis, 97% had elevated serum cholylglycine levels, while only 61% had significant jaundice (serum bilirubin greater than 5 mg/dl). In patients without tissue cholestasis, 66% had elevated serum cholylglycine and 13.5% jaundice. Highly significant statistical correlations (P less than 0.0001) were found between cholestasis and malnutrition, prothrombin time, AST, alkaline phosphatase, bilirubin, Maddrey's discriminant function, serum cholylglycine level, albumin, and histologic severity score. In group I, 54% survived 60 months versus 22% in group II (P less than 0.0001). Highly significant statistical correlations (P less than 0.0001) were noted between serum cholylglycine levels and the parameters enumerated earlier, but not with survival. We conclude that tissue cholestasis is a highly significant prognostic indicator of outcome in alcoholic hepatitis and is more consistently associated with bile salt retention than jaundice.

Abstract
We report the first detailed study of hepatic morphology in 28 biopsies from 16 Greenland Eskimo children with fatal familial cholestatic syndrome. The changes were categorized as early, intermediate and late. In the early stage, until 5 months of age, changes were restricted to zone 3, consisting of cholestasis and rosette formation without fibrosis. In the intermediate stage, from 5 to 14 months, cholestasis persisted and rosette formation increased, both with further extension into zone 2. Perisinusoidal fibrosis developed, first in zone 3 and later in zone 1. The late stage, from 17 to 60 months, showed a further increase in cholestasis and rosette formation, and fibrosis of zones 3 and 1 in nearly all biopsies. Portal to portal and portal to central fibrosis was evident with resulting cirrhosis in 2 of 7 patients. The morphological features can be summarized as pure cholestasis with prominent rosette formation followed by zone 3 fibrosis, zone 1 fibrosis, and, cirrhosis. Other characteristics are the virtual absence of inflammation and the lack of anatomical abnormalities such as paucity of bile ducts. The changes and their progression resemble those of Byler disease. Clinical and biochemical features are also largely similar, except for the presence of thrombocytosis in many of the Eskimo patients.

Abstract
A syndrome of intrahepatic cholestasis leading to death in early childhood was studied in 16 Greenland Eskimo children. The pedigrees are compatible with autosomal recessive inheritance. Jaundice, bleeding, pruritus, malnutrition, steatorrhoea, osteodystrophy and dwarfism were typical clinical features. Eight had died between the ages of six weeks and three years due to bleeding or infections. Hyperbilirubinaemia, profound hypoprothrombinaemia, thrombocytosis and elevated alkaline phosphatase levels were evident. Serum calcium, phosphate and parathyroid hormone levels indicated a secondary hyperparathyroidism. Hepatic fibrosis developed with increasing age. Follow-up of the surviving patients was 4 to 30 months. The aetiology of the disease is unknown. The syndrome has some features in common with previously described patients with familial intrahepatic cholestasis. No specific treatment is available. Genetic counselling is essential.

Abstract
This report concerns 105 patients with benign biliary stricture operated on at the Cleveland Clinic from 1970 through 1984; in 102 patients the stricture was iatrogenic. The mean follow-up was 5 years (3 months to 13 years). Fifty-eight patients (55%) had undergone one or more attempts at correction of the stricture before referral to us; in 47 patients (45%) we performed the first corrective repair. Percutaneous transhepatic cholangiography was the optimal preoperative diagnostic procedure to define the site of stricture. Most patients had undergone a biliary-intestinal anastomosis, either choledochoduodenostomy, choledochojejunostomy, or hepatojejunostomy. Morbidity and mortality rates were 13% and 4%, respectively. The results of operative repair were correlated with the number of previous operations, site of stricture, type of operation, presence of a fistula, presence of cirrhosis, and length of T or Y tube stenting. The overall recurrence rate after a first operation was 18% and after a second operation was 26%. With continued attempts at repair, eventual success was achieved in 93% of patients.

Abstract
Presenting characteristics, long-term outcome, and techniques used in the diagnosis of 143 infants with suspected biliary obstruction are reviewed. Sixty-nine patients had surgically confirmed extrahepatic disease and 74 had intrahepatic disorders. A disproportionate number of infants with intrahepatic disease were boys (p = 0.013), low birthweight (p = 0.001), or had siblings with liver disease (p = 0.017). An initial total bilirubin of 20 mg/dl or greater was rare except in the intrahepatic disease category of neonatal hepatitis of known cause (p = 0.006). The initial percutaneous liver biopsy correctly predicted the ultimate diagnosis in 94 percent of all 143 patients. A methodological outline to diagnosis is presented, emphasizing early recognition of symptoms and careful follow-up with hepatobiliary imaging, liver biopsy, and surgical exploration, if required, until definitive diagnosis is made. This approach has aided us in reducing the age of diagnosis of biliary atresia from 12.8 +/- SD 7.3 weeks during the period 1971 through 1979 to 6.8 +/- SD 2.6 weeks from 1980 to 1982 (p = 0.0015). Eighteen-month survival has improved from 25 to 60 percent.
