Abstract
About 20% of adults worldwide have gallstones which are solid conglomerates in the biliary tree made of cholesterol monohydrate crystals, mucin, calcium bilirubinate, and protein aggregates. About 20% of gallstone patients will definitively develop gallstone disease, a condition which consists of gallstone-related symptoms and/or complications requiring medical therapy, endoscopic procedures, and/or cholecystectomy. Gallstones represent one of the most prevalent digestive disorders in Western countries and patients with gallstone disease are one of the largest categories admitted to European hospitals. About 80% of gallstones in Western countries are made of cholesterol due to disturbed cholesterol homeostasis which involves the liver, the gallbladder and the intestine on a genetic background. The incidence of cholesterol gallstones is dramatically increasing in parallel with the global epidemic of insulin resistance, type 2 diabetes, expansion of visceral adiposity, obesity, and metabolic syndrome. In this context, gallstones can be largely considered a metabolic dysfunction-associated gallstone disease, a condition prone to specific and systemic preventive measures. In this review we discuss the key pathogenic and clinical aspects of gallstones, as the main clinical consequences of metabolic dysfunction-associated disease.

Abstract
OBJECTIVE To explore the surgical risk factors of laparoscopic left-sided hepatectomy for hepatolithiasis and establish and validate a nomogram to estimate the corresponding surgical risks. METHODS Patients with hepatolithiasis who underwent laparoscopic left-sided hepatectomy were retrospectively enrolled. Demographic data, clinicopathological parameters, and surgical factors were collected. Three hundred fifty-three patients were enrolled and randomly divided into training set (n=267) and validation set (n=86) by 3:1. Conversion to laparotomy was used as a surrogate index to evaluate the surgical risk. Univariate analysis was used to screen potential surgical risk factors, and multivariate analysis using logistic regression model was used to screen independent surgical risk factors. Nomogram predicting the surgical risks was established based on the independent risk factors. Discrimination, calibration, decision curve, and clinical impact analyses were used to evaluate the performance of the nomogram on the statistical and clinical aspects both in the training and validation sets. RESULTS Five independent surgical risk factors were identified in the training set, including recurrent abdominal pain, bile duct stricture, ASA classification ≥2, extent of liver resection, and biliary tract T tube drainage. No collinearity was found among these five factors, and a nomogram was established. Performance analyses of the nomogram showed good discrimination (AUC=0.850 and 0.817) and calibration (Hosmer-Lemeshow test, p=0.530 and 0.930) capabilities both in the training and validation sets. Decision curve and clinical impact analyses also showed that the prediction performance was clinically valuable. CONCLUSIONS A nomogram was established and validated to be effective in evaluating and predicting the surgical risk of patients undergoing laparoscopic left-sided hepatectomies for hepatolithiasis.

Abstract
Objectives: To investigate the correlation between psychological resilience, social support, and coping styles in patients with complicated hepatolithiasis. Methods: The objective sampling method was used in this study to select a total of 156 patients with complicated hepatolithiasis in a Third-class Grade A hospital in Changsha, Hunan Province from January to December 2019. Self-designed general data questionnaire, the Connor-Davidson Resilience Scale (CD-RISC), the Social Support Rating Scale (SSRS), and the Simplified Coping Style Questionnaire (SCSQ) were used to conduct a questionnaire investigation. Spearman correlation analysis was used to analyze the correlation between psychological resilience, social support, and coping styles in patients with complicated hepatolithiasis. Results: Both the total score of psychological resilience (45.79 ± 16.28) and social support (35.71 ± 9.92) of patients with complicated hepatolithiasis were significantly lower than those of the domestic norm. The total score of psychological resilience of patients with complicated hepatolithiasis was positively correlated with the total score of social support (r = 0.570, p < 0.01). The total score of psychological resilience and its three dimensions were positively correlated with the positive coping (r = 0.682, 0.673, 0.663, 0.535, p < 0.01)and negatively correlated with negative coping (r = −0.240, −0.207, −0.221, −0.286, p < 0.01). Conclusions: This study indicated that strengthening social support and improving the coping style of patients with complicated hepatolithiasis are helpful to improve their psychological resilience, which provided theory basis and reference for further intervention measures to improve social support system and coping styles.

Abstract
PURPOSE OF REVIEW Hepatolithiasis is a disease characterized by intrahepatic stone formation. In this article, we review the features of this disease and explore the established and emerging treatment modalities. RECENT FINDINGS Recent reports show an increasing prevalence of hepatolithiasis, likely owed to increased immigration and shifts in the Western diet. New pharmacotherapy options are limited and are often only supportive. Endoscopic intervention still cruxes on removal of impacted stones, though new techniques such as bile duct exploratory lithotomy and lithotripsy continue to advance management. Although hepatectomy of the effected portion of the liver offers definitive therapy, alternative less invasive modalities such as combined endoscopic/interventional radiology modalities have been utilized in select patients. Additionally, liver transplant serves as an option for otherwise incurable hepatolithiasis with coexisting liver dysfunction. Multiple emerging pharmacologic and procedural interventions may provide novel treatment for hepatolithiasis. While definitive therapy remains resection of affected liver segments, these modalities offer hope for less invasive approaches in the future.

Abstract
Cholangiopathies describe a group of conditions affecting the intrahepatic and extrahepatic biliary tree. Impairment to bile flow and chronic cholestasis cause biliary inflammation, which leads to more permanent damage such as destruction of the small bile ducts (ductopaenia) and biliary cirrhosis. Most cholangiopathies are progressive and cause end-stage liver disease unless the physical obstruction to biliary flow can be reversed. This review considers large-duct cholangiopathies, such as primary sclerosing cholangitis, ischaemic cholangiopathy, portal biliopathy, recurrent pyogenic cholangitis and Caroli disease.

Abstract
Bile is composed of multiple macromolecules, including bile acids, free cholesterol, phospholipids, bilirubin, and inorganic ions that aid in digestion, nutrient absorption, and disposal of the insoluble products of heme catabolism. The synthesis and release of bile acids is tightly controlled and dependent on feedback mechanisms that regulate enterohepatic circulation. Alterations in bile composition, impaired gallbladder relaxation, and accelerated nucleation are the principal mechanisms leading to biliary stone formation. Various physiologic conditions and disease states alter bile composition and metabolism, thus increasing the risk of developing gallstones.

Abstract
Approximately twenty per cent of adults have gallstones making it one of the most prevalent gastrointestinal diseases in Western countries. About twenty per cent of gallstone patients requires medical, endoscopic, or surgical therapies such as cholecystectomy due to the onset of gallstone-related symptoms or gallstone-related complications. Thus, patients with symptomatic, uncomplicated or complicated gallstones, regardless of the type of stones, represent one of the largest patient categories admitted to European hospitals. This review deals with the important critical care aspects associated with a gallstone-related disease.

Abstract
The adenosine 5'‑triphosphate binding cassette subfamily B member (ABCB)11 gene is involved in bile transport, and mutations in this gene are associated with cholestasis and cholelithiasis. Therefore, the aim of the present study was to investigate the association between ABCB11 gene mutation and primary intrahepatic stone (PIS)s and to investigate the mechanism through which ABCB11 gene mutations affect the expression of the corresponding protein. Mutations of the ABCB11 gene in 443 PIS patients and 560 healthy participants were detected by exon sequencing. The expression levels of ABCB11 mRNA and bile salt export pump (BSEP) protein in the liver tissues of patients with PISs were measured by quantitative polymerase chain reaction and western blot analysis. The mutant plasmids constructed by site‑directed mutagenesis of the human BSEP gene were transfected into human embryonic kidney 293 (293) cells and Madin‑Darby canine kidney (MDCK) cells, and the expression and distribution of rs118109635 of BSEP was measured. There were two significant mutations in the ABCB11 gene of the PIS patients compared with the healthy population; a missense mutation, rs118109635 (P=0.025), and a synonymous mutation, rs497692 (P=0.006). The two mutations were associated with the occurrence of preoperative jaundice (P=0.026, and P=0.011, respectively). The expression levels of BSEP in PIS patients with the missense mutation rs118109635 was decreased, whereas its mRNA expression levels remained unchanged. In PIS patients with the synonymous mutation rs497692, the expression levels of ABCB11 were decreased at both the mRNA and protein level. It was also found that mutation A865V reduced the expression levels of BSEP in 293 cells at the cellular level; its distribution in MDCK cell membranes was decreased, whereas its mRNA levels remained unchanged. The mutated loci at rs118109635 and rs497692 of the ABCB11 gene were correlated with PISs, causing a decreased expression of BSEP and reduced distribution of the protein in the cell membrane. Therefore, mutations at rs118109635 and rs497692 of the ABCB11 gene may be risk factors for PISs.

Abstract
Background The objective of this study was to determine the clinical presentation, systemic risk factors, source of infective microorganism, treatment outcomes, and prognostic indicators of endogenous endophthalmitis at a main tertiary referral hospital for uveitis in Malaysia. A retrospective review of medical records of 120 patients (143 eyes) with endogenous endophthalmitis over a period of 9 years between January 2007 and December 2015 was undertaken. Results Identifiable systemic risk factors were present in 79.2%, with the majority related to diabetes mellitus (60.0%). The most common source of bacteremia was urinary tract infection (17.5%). A positive culture from ocular fluid or other body fluids was obtained in 82 patients (68.9%), and the blood was the highest source among all culture-positive results (42.0%). Gram-negative organisms accounted 42 cases (50.6%) of which Klebsiella pneumonia was the most common organism isolated (32.5%). Sixty-nine eyes (48.6%) were managed medically, and 73 eyes (51.4%) underwent vitrectomy. Final visual acuity of counting fingers (CF) or better was achieved in 100 eyes (73.0%). Presenting visual acuity of CF or better was significantly associated with a better final acuity of CF or better (p = 0.001). Conclusions The visual prognosis of endogenous endophthalmitis is often poor, leading to blindness. As expected, gram-negative organisms specifically Klebsiella pneumonia were the most common organisms isolated. Urinary tract infection was the main source of infection. Poor presenting visual acuity was significantly associated with grave visual outcomes. A high index of suspicion, early diagnosis, and treatment are crucial to salvage useful vision.

Nerve growth factor upregulates sirtuin 1 expression in cholestasis: a potential therapeutic target. Exp Mol Med 2018; 50:e426.

Abstract
This study investigated the regulatory role of nerve growth factor (NGF) in sirtuin 1 (SIRT1) expression in cholestatic livers. We evaluated the expression of NGF and its cognate receptors in human livers with hepatolithiasis and the effects of NGF therapy on liver injury and hepatic SIRT1 expression in a bile duct ligation (BDL) mouse model. Histopathological and molecular analyses showed that the hepatocytes of human diseased livers expressed NGF, proNGF (a precursor of NGF), TrkA and p75NTR, whereas only p75NTR was upregulated in hepatolithiasis, compared with non-hepatolithiasis livers. In the BDL model without NGF therapy, p75NTR, but not TrkA antagonism, significantly deteriorated BDL-induced liver injury. By contrast, the hepatoprotective effect of NGF was abrogated only by TrkA and not by p75NTR antagonism in animals receiving NGF therapy. Intriguingly, a positive correlation between hepatic SIRT1 and NGF expression was found in human livers. In vitro studies demonstrated that NGF upregulated SIRT1 expression in mouse livers and human Huh-7 and rodent hepatocytes. Both NGF and proNGF induced protective effects against hydrogen peroxide-induced cytotoxicity in Huh-7 cells, whereas inhibition of TrkA and p75NTR activity prevented oxidative cell death. Mechanistically, NGF, but not proNGF, upregulated SIRT1 expression in human Huh-7 and rodent hepatocytes via nuclear factor (NF)-κB activity, whereas NGF-induced phosphoinositide-3 kinase/Akt, extracellular signal–regulated kinase and NF-κB signaling and SIRT1 activity were involved in its hepatoprotective effects against oxidative injury. These findings suggest that pharmacological manipulation of the NGF/SIRT1 axis might serve as a novel approach for the treatment of cholestatic disease.

Abstract
Bile salts are natural detergents required to solubilise dietary fat and lipid soluble vitamins. They are synthesised in hepatocytes and secreted into the luminal space of the biliary tree by the bile salt export pump (BSEP), an ATP-binding cassette (ABC) transporter in the canalicular membrane. BSEP deficiency causes cytotoxic accumulation of bile salts in the hepatocyte that results in mild-to-severe forms of cholestasis. The resulting inflammation can also progress to hepatocellular cancer via a novel mechanism involving upregulation of proliferative signalling pathways. A second ABC transporter of the canalicular membrane is also critical for bile formation. ABCB4 flops phosphatidylcholine into the outer leaflet of the membrane to be extracted by bile salts in the canalicular space. These mixed micelles reduce the detergent action of the bile salts and protect the biliary tree from their cytotoxic activity. ABCB4 deficiency also causes cholestasis, and might be expected to cause cholangitis and predispose to liver cancer. Non-synonymous SNPs in ABCB4 have now been described in patients with liver cancer or with inflammatory liver diseases that are known to predispose to cancer, but data showing that the SNPs are sufficiently deleterious to be an etiological factor are lacking. Here, we report the first characterisation at the protein level of six ABCB4 variants (D243A, K435T, G535D, I490T, R545C, and S978P) previously found in patients with inflammatory liver diseases or liver cancer. All significantly impair the transporter with a range of phenotypes exhibited, including low abundance, intracellular retention, and reduced floppase activity, suggesting that ABCB4 deficiency is the root cause of the pathology in these cases.

Abstract
Hepatolithiasis is highly prevalent in Asia but rare in Western countries. However, the incidence of hepatolithiasis may be increasing in Western countries due to the increased rate of immigration from areas where hepatolithiasis is prevalent. There are many non-surgical treatments for hepatolithiasis, but surgical management remains the best curative treatment for some cases of hepatolithiasis. Surgical treatments can remove biliary stones and relieve stricture of the bile ducts. This review describes the indications for and the outcomes of surgical treatment of hepatolithiasis, including liver resection and liver transplantation.

Abstract
Background: Percutaneous transhepatic cholangioscopy (PTCS) is one option for treating hepatolithiasis without surgical resection. This approach can use conventional biliary drainage methods over a long period, but a shorter procedure needs to be evolved. Objective: To evaluate the short-term and the long-term therapeutic outcomes of percutaneous transhepatic cholangioscopic lithotripsy (PTCSL) in comparison with conventional PTCS. Methods: In this retrospective study, 118 patients with hepatolithiasis were enrolled who underwent treatment in our hospital between March 2007 and July 2014. About 67 of them received PTCSL and the remaining 51 patients received conventional PTCS. Preoperative data, surgical operation-related records, the postoperative therapeutic effect, and the long-term hepatolithiasis recurrence rate were collected for comparison between the 2 groups. Results: The age, sex, and surgical history were similar between the 2 groups, but there was a significant difference in the Child-Pugh score, with more grade 3 patients in the PTCS group (P=0.002). However, the operation time, intraoperative blood infusion, and the blood loss were similar between the 2 groups. The final clearance ratio of calculus in the PTCSL group was significantly better than in the PTCS group after multivariate analysis (P=0.021; OR=0.201; 95% CI, 0.051-0.785). Calculus recurrence was 9% (PTCSL) and 22% (PTCS). The postoperative hospital stay was significantly shorter in the PTCSL group (P=0.001; OR=1.337; 95% CI, 1.132-1.58). Conclusions: PTCSL was a satisfactory therapeutic option for hepatolithiasis treatment, with less operation time and a superior long-term therapeutic effect compared with conventional PTCS.

Abstract
PURPOSE To study the clinical features of endogenous endophthalmitis (EE) in sample patient populations from the USA and South Korea over an 8-year period. METHODS We reviewed data from 128 eyes of 60 American and 48 Korean patients diagnosed with EE and compared their clinical characteristics. RESULTS Fungemia and liver abscess were the most common extraocular infection sources among American (26.7%) and Korean patients (33.3%), respectively. Klebsiella pneumoniae and Candida species were the most common pathogens of EE in the Korean and the American patients, respectively. Endophthalmitis caused by fungi had a better visual prognosis than that caused by bacteria (p = 0.001). Vitrectomy was beneficial for eyes with EE due to virulent bacteria presenting with worse than counting finger vision. CONCLUSIONS The predisposing conditions and responsible organisms for EE vary in different regions of the world. The visual prognosis was strongly influenced by the underlying pathogen.

Abstract
Ascariasis lumbricoides is one of the most common helminthic infestations in humans. Despite the fact that the prevalence of ascariasis in developed countries has been decreasing, biliary ascariasis can cause serious complications, such as acute cholangitis, pancreatitis, and liver abscess. Here we presented a rare ascariasis-related complication-hepatolithiasis.A 60-year-old female patient had symptoms of recurrent cholangitis. Abdominal computed tomography scan revealed left intrahepatic duct stones with left liver lobe atrophy. Endoscopic retrograde cholangiopancreatography was performed, but the stones could not be removed due to left main intrahepatic duct stenosis. The patient was treated with left hemi-hepatectomy. Unexpectedly, Ascaris ova were found on the histopathological examination. She received antihelminthic therapy orally and was on regular follow-up without any complications.Our study indicates that clinicians should be aware of biliary ascariasis in patients with hepatolithiasis, though not living in endemic areas.

Abstract
Hepatectomy is a safe and effective treatment for intrahepatic stones (IHSs). However, the resection plane for right-sided stones distributed within 2 segments is obstacle because of atrophy-hypertrophy complex formation of the liver and difficult dissection of segmental pedicle within the Glissonean plate by conventional approach. Thus, we devised segmental bile duct-targeted liver resection (SBDLR) for IHS, which aimed at completely resection of diseased bile ducts. This study aimed to evaluate the outcomes of SBDLR for right-sided IHSs. From January 2009 to December 2013, 107 patients with IHS treated by SBDLR in our center were reviewed in a prospective database. Patients' intermediate and long-term outcomes after SBDLR were analyzed. A total of 40 (37.4%) patients with localized right-sided stone and 67 (62.7%) patients with bilateral stones underwent SBDLR alone and SBDLR combined with left-sided hepatectomy, respectively. There was no hospital mortality of this cohort of patients. The postoperative morbidity was 35.5%. The mean intraoperative blood loss was 414 mL (range: 100-2500). Twenty-one (19.6%) patients needed red blood cells transfusion. The intermediate stone clearance rate was 94.4%; the final clearance rate reached 100% after subsequent postoperative cholangioscopic lithotomy. Only 2.8% patients developed stone recurrence in a median follow-up period of 38.3 months. SBDLR is a safe and effective treatment for right-sided IHS distributed within 2 segments. It is especially suitable for a subgroup of patients with bilateral stones whose right-sided stones are within 2 segments and bilateral liver resection is needed.

Abstract
PURPOSE To identify the clinical features, treatment outcomes, and prognostic factors of endogenous endophthalmitis in multiple tertiary referral centers of South Korea over a 6-year period. METHODS The authors conducted a retrospective review of medical records of 57 eyes of 43 patients diagnosed with endogenous endophthalmitis from January 2005 to December 2011, which was referred to tertiary referral centers. RESULTS Fifty-seven cases of 43 patients were followed for a mean of 18.7 months (range, 0.5-50 months). The common underlying diseases were diabetes mellitus (46.5%) and liver cirrhosis (20.93%). Liver abscess (39.5%) was the most common infection source. Among prognostic factors, the initial visual acuity was associated with favorable visual outcome significantly (P < 0.001). Endogeneous endophthalmitis with gram-negative bacteria had worse visual outcomes than gram-positive bacteria or fungus (P = 0.014). CONCLUSION Similar to the findings of previous East Asian studies, this study showed that Klebsiella pneumoniae was the most common causative organism of endogenous endophthalmitis and liver abscess was the most common infection focus. Although endogenous endophthalmitis is generally associated with poor visual acuity outcomes, the prognosis depends mainly on the initial visual acuity and the pathogen.

Abstract
Variations of the ABCB4 and ABCB11 genes affect the composition of bile and are associated with cholestasis and cholelithiasis. However, their roles in the formation of primary intrahepatic stones (PIS) remains to be elucidated. The aim of the present study was to determine whether there is an association between PIS and variations in these genes. Exon sequencing was performed in order to analyze the ABCB4 and ABCB11 genes of 176 patients with PIS and 178 healthy subjects. One mutation in ABCB4 (no. 69233, G>A) and two other mutations in ABCB11, reference single nucleotide polymorphism (rs)118109635 and rs497692, were identified in association with PIS (P<0.001, P=0.04 and P=0.02, respectively). A synonymous mutation at no. 69233 G>A was detected in exon 26 of ABCB4 in 23 heterozygous patients with PIS. This mutation was not detected in healthy individuals or in the Single Nucleotide Polymorphism Database. No. 69233 G>A in ABCB4 was not associated with altered protein expression but with a reduced rate of PIS recurrence (P=0.01). The missense mutation rs118109635 was located on exon 21 of ABCB11 and was associated with the increased expression of ABCB11 protein (P=0.032) as well as altered bile salt export pump function. Another synonymous mutation, rs497692 in exon 24 was reported to decrease ABCB11 protein expression (P=0.001). In addition, the mutations of ABCB11 were associated with preoperative jaundice (P<0.001 and P=0.03, respectively). Consistently decreased levels of ABCB11 protein were associated with recurrent episodes of cholangitis (P=0.006) and preoperative jaundice (P=0.015). By contrast, ABCB4 expression was not found to be associated with clinical manifestations of PIS.

Abstract
BACKGROUND This study intends to determine the risk factor(s) for intraoperative hemobilia in patients with hepatolithiasis and examine whether the occurrence of intraoperative hemobilia influences the rate of early postoperative complications. METHODS A retrospective analysis of 867 eligible patients was performed. Patients were divided into 2 groups: group A (hemobilia, n = 76) and group B (nonhemobilia, n = 791). RESULTS The incidence of intraoperative hemobilia was 8.8% (76/867). Independent risk factors of intraoperative hemobilia for patients with hepatolithiasis were interval between surgery and latest attack of acute cholangitis less than or equal to 38.8 days; preoperative attack of acute severe cholangitis; and intrahepatic duct stricture. Group A had a higher incidence of early postoperative complications than group B. Shorter interval between surgery and latest attack of acute cholangitis correlated with intraoperative hemobilia and postoperative complications. CONCLUSION The severity and time of onset of preoperative acute cholangitis influence the risk of intraoperative hemobilia, which is positively correlated with early postoperative complications.

Abstract
BACKGROUND/AIMS To investigate the incidence of cholangiocarcinoma in patients with hepatolithiasis with or without previous resection of liver. METHODS From 2002 to 2009, we retrospectively reviewed 117 patients who were diagnosed and treated for hepatolithiasis in Korea University Guro Hospital. Among the 117 patients, 55 patients who were lost during follow-up were excluded, and 62 patients were eligible for analysis. The hepatic resection group (n=25) included patients who underwent left hemihepatectomy (n=2); left lateral segmentectomy (n=10); left lobectomy (n=9); right lobectomy (n=3); or wedge resection (n=1). The nonhepatic resection group (n=37) included transhepatic cholangiographic lithotomy and endoscopic retrograde cholangiopancreatography-treated patients. The mean follow-up period was 47 months. RESULTS The incidence of cholangiocarcinoma while patients were followed for hepatolithiasis was 12.9% (8/62) (hepatic resection group, three cases [12%] vs nonhepatic resection group, five cases [13.5%]; p=1.000). The mean follow-up period was 53 months (47±11 months) until the diagnosis of cholangiocarcinoma. CONCLUSIONS There was no difference in the incidence of cholangiocarcinoma according to previous liver resections. Patients with hepatolithiasis should be carefully followed up for detection of cholangiocarcinoma even after a previous liver resection.

Abstract
BACKGROUND Hepatolithiasis affecting the left hepatobiliary system is common in the Asia Pacific region. This aim of this study was to describe an experience with the diagnosis and treatment of patients with isolated left-sided hepatolithiasis. METHODS One hundred and ten patients with isolated left-sided hepatolithiasis who underwent a left-sided hepatic resection between January 1999 and February 2010 were included for further analysis. The clinical profile, cholangiograms, operative procedures and early and late results were examined. RESULTS Analysis of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) findings revealed left hepatic ductal anatomical details in 101 patients. Three types of left hepatic ductal variations were observed (type 1 in 90.1%, type 2 in 5.9% and type 3 in 4.0% patients). Eighty-four (76.4%) patients had the presence of strictures in the left hepatic ductal system and in 26 (23.6%) patients no strictures could be seen. Out of 84 patients with strictures, 78 could be classified (type I in 89.7% and type II in 10.3%). Of the 110 patients, 75 (68.2%) underwent a left lateral sectionectomy, 33 (30%) a left hepatectomy and 2 (1.8%) patients were treated with a left hepatectomy combined with a caudate lobe resection. Of the patients who underwent a left hepatectomy 11.4% developed a bile leak. Eight per cent of patients who underwent a left lateral sectionectomy had infective complications. During a median follow-up period of 63 (range 3-134) months, 2 (2.1%) patients were discovered to have residual stones and five (5.2%) others possessed recurrent stones. CONCLUSIONS This study highlights the impact of the presence or absence of bile duct stricture on the clinical and histological profile of patients as well as their operative and the post-operative behaviour. It is concluded that hepatic resection is an appropriate treatment modality in localized left-sided hepatolithiasis.

Abstract
Recurrent pyogenic cholangitis (RPC), or oriental cholangiohepatitis, is characterized by intrabiliary pigment stone formation, whose main manifestation consists of recurrent episodes of cholangitis, although other biliopancreatic complications can also occur. RPC develops mainly in Asian patients, in whom this entity is one of the main causes of acute abdominal pain. The differential diagnosis should be established with all other entities associated with intrahepatic stone formation, which is more common in Asian countries compared with the predominance of gallstone formation in the West. The diagnostic and therapeutic approach requires collaboration among gastroenterologists, radiologists and gastrointestinal surgeons. We review the most important clinical, diagnostic and therapeutic features of this entity, which, although clearly predominant in Asia, is increasingly diagnosed in our setting.

Abstract
Patients suffering from primary sclerosing cholangitis (PSC) show considerable differences regarding clinical manifestations (i.e. large duct versus small-duct PSC, presence or absence of concomitant inflammatory bowel disease), disease progression, risk for malignancy and response to therapy, raising the question whether PSC may represent a mixed bag of diseases of different aetiologies. The growing list of secondary causes and diseases 'mimicking' or even overlapping with PSC (e.g. IgG4-associated sclerosing cholangitis), which frequently causes problems in clear-cut discrimination from classic PSC and the emerging knowledge about potential disease modifier genes (e.g. variants of CFTR, TGR5 and MDR3) support such a conceptual view. In addition, PSC in children differs significantly from PSC in adults in several aspects resulting in distinct therapeutic concepts. From a clinical perspective, appropriate categorization and careful differential diagnosis are essential for the management of concerned patients. Therefore, the aim of the current review is to summarize current and evolving pathophysiological concepts and to provide up-to-date perspectives including future treatment strategies for PSC.

Abstract
BACKGROUND Why 3.3% to 10% of all patients with hepatolithiasis develop intrahepatic cholangiocarcinoma (ICC) remains unknown. We carried out a hospital-based case-control study to identify risk factors for the development of ICC in patients with hepatolithiasis in China. METHODS Eighty-seven patients with pathologically diagnosed hepatolithiasis associated with ICC and 228 with hepatolithiasis alone matched by sex, age (+/-2 years), hospital admittance and place of residence were interviewed during the period of 2000-2008. Odds ratios (OR) and 95% confidence intervals (CI) were calculated for each risk factor. RESULTS Among the patients with hepatolithiasis associated with ICC, the mean age was 57.7 years and 61.0% were female. Univariate analysis showed that the significant risk factors for ICC development in hepatolithiasis were smoking, family history of cancer, appendectomy during childhood (under age 20), and duration of symptoms >10 years. In multivariate stepwise logistic regression analysis, smoking (OR=1.931, 95% CI: 1.000-3.731), family history of cancer (OR=5.175, 95% CI: 1.216-22.022), and duration of symptoms >10 years (OR=2.348, 95% CI: 1.394-3.952) were independent factors. CONCLUSION Smoking, family history of cancer and duration of symptoms >10 years may be risk factors for ICC in patients with hepatolithiasis.

Abstract
Endophthalmitis is a rare but sight-threatening complication that can occur after ocular surgery or trauma or as a consequence of systemic infection. To optimize visual outcome, early diagnosis and treatment are essential. Over recent decades, advances in hygienic standards, improved microbiologic and surgical techniques, development of powerful antimicrobial drugs, and the introduction of intravitreal antibiotic therapy have led to a decreased incidence and improved management of endophthalmitis. However, endophthalmitis still represents a serious clinical problem. This review focuses on current principles and techniques for evaluation and treatment of endophthalmitis. In addition, it addresses recent developments regarding antimicrobial treatment and prophylaxis of infectious endophthalmitis.

Abstract
Aim. Determination of first line treatment with limited hepatectomy or Anatomical hepatectomy provides better clinical outcome. Methods. Immediate and long-term outcomes of 106 patients who underwent partial hepatectomy for RH at our institution from January 2001 to February 2005 were analyzed retrospectively. Clinical end-points included time to recovery of hepatic function, residual stones, infection of the liver remnant, bile leakage, recurrent stones, morbidity, and mortality. Results. LH was performed in 59 patients and AH in 47 patients as first-line treatment. The time of hepatic function recovery was not statistically different between the two groups (P > .05). However, Patients in AH group suffered from less residual stones (P < .05), less infection of the raw surface of liver remnant (P < .05), and less bile leakage (P < .05), with a median follow-up of 40.3 ± 0.8 months (range 3–48), and AH group suffered a less recurrent stone rate (P < .05). No difference in morbidity, and mortality rates between the two groups. Conclusion. AH is a safe and effective treatment for RH, with a fair rate of surgical complications, it should be considered as first-line treatment of RH.

Abstract
BACKGROUND Recently, high stone recurrence and biliary restenosis rates in hepatolithiasis patients have been confirmed to be closely related to chronic proliferative cholangitis (CPC). However, the effective management of CPC has not yet been established. METHODS AND RESULTS A vicious cycle exists between the presence of intrahepatic calculi and CPC: both the stone itself and secondary biliary infection can stimulate persistent hyperplasia in the biliary duct wall, leading to the occurrence of CPC and biliary stricture. The recurrent attacks of CPC will, in turn, facilitate new stone formation via mucoglycoprotein production, or induced biliary stricture and cholestasis. Thus, even when the stone is completely removed and the biliary tract stenosis is corrected, residual CPC will persist and progress, with an underlying risk for postoperative stone recurrence and biliary tract restenosis. Therefore, the perfect hepatolithiasis treatment would target stone removal and correction of the biliary tract stricture, as well as control of postoperative residual CPC. In fact, CPC, the management of which has been traditionally ignored, is the key to breaking this vicious cycle. CONCLUSIONS Overall, the subsequent treatment of residual CPC after operation or choledochoscopic lithotomy would be helpful to decrease postoperative stone recurrence and the rate of biliary restenosis. Adding such treatment would reduce the incidence of surgical reintervention and choledochoscopic lithotomy, and it would also improve the postoperative hepatolithiasis outlook.

Abstract
BACKGROUND AND AIM Roux-en-Y hepaticojejunostomy (RYHJ) is usually used to treat benign strictures of hilar bile ducts. However, RYHJ might also induce ascending cholangitis and recurrent hepatolithiasis. The present study aims to introduce a modified hepatic portal choledochoplasty with a pedicled graft of gallbladder (HPC) to treat this disease. METHODS One hundred and forty-nine patients, who had undergone HPC or RYHJ from January 1997 to January 2006 in our institutions, were included in this study, and the clinical data were retrospectively collected and analyzed. RESULTS The incidences of perioperative bile leakage and inflammatory ileus in patients treated with HPC were slightly lower than RYHJ without significant difference (1.89% vs 2.08% and 3.77% vs 5.21%, both P > 0.05). However, in a long-term follow up, patients treated with HPC had significantly lower incidences of cholangitis and recurrent hepatolithiasis (5.66% and 3.77%, respectively) than those treated with RYHJ (cholangitis, 21.88%; hepatolithiasis, 16.67%; both P < 0.05). CONCLUSION Compared to RYHJ, HPC is a safer and more efficient method to treat benign strictures of hilar biliary ducts. It preserves the sphincter of Oddi and normal biliary duct pressure, thus avoiding bile reflux into the bile duct.

Abstract
BACKGROUND AND AIM A high prevalence of intrahepatic stones in some areas of East Asia has been believed to be related with Clonorchis sinensis infection. The authors conducted a hospital-based case-control study to evaluate the role of Clonorchis sinensis infection as a risk factor for the development of gallstones in Korea. METHODS The cases of 138 patients with gallstones (intrahepatic 44, gallbladder 67, and extrahepatic 27) and matched controls underwent microscopy for C. sinensis, serological tests for C. sinensis using enzyme-linked immunosorbent assay, radiological examinations, and interviews concerning the history of eating raw freshwater fish. We assessed a relationship of three types of gallstones and variables regarding C. sinensis by using univariate and multivariate statistical analyses. RESULTS Univariate statistical analyses showed that radiological evidence of C. sinensis and recent history of eating raw freshwater fish were related to an increased risk of intrahepatic stones (P = 0.0002 and 0.0039, respectively). According to multivariate statistical analyses, radiological evidence of C. sinensis was the only risk factor for intrahepatic stones (odds ratio = 7.835; 95% confidence interval = 1.671-36.724). Any evidence regarding C. sinensis was not related to an increased risk of either gallbladder or extrahepatic stones. CONCLUSION Radiological evidence of C. sinensis was significantly associated with intrahepatic stones.

Abstract
BACKGROUND AND AIM To examine associations between lifestyle risk factors and intrahepatic stone (IHS), we conducted a case-control study in Taiwan, which has the highest incidence of IHS in the world. METHODS Study subjects were 151 patients newly diagnosed with IHS at Chang Gung Memorial Hospital between January 1999 and December 2001. Two control subjects per case were selected randomly from patients who underwent minor surgery at the same hospital and from family members or neighbors of the hospital staff. Controls were matched to each case by age and gender. Information on lifestyle factors was collected using a self-administered questionnaire. Strength of associations was assessed using odds ratios derived from conditional logistic models. RESULTS Female patients were significantly shorter than female controls. Compared to subjects with two or fewer children, odds ratios for those with six or more children were 20.4 in men (95% confidence interval, 1.89-221) and 2.82 (0.97-8.22) in women. Increasing level of education lowered the risk of intrahepatic stone (trend P = 0.004 for men and < 0.0001 for women). Women who had consumed ground-surface water for a long period had a somewhat increased risk (trend P = 0.05). CONCLUSION Lower socioeconomic status and poor hygiene may be involved in the development of intrahepatic stones.

Abstract
The high recurrence of hepatolithiasis has not been settled effectively until now, which lead us to present a new therapy of the chemical bile duct embolization to resolve it. In our selected 2 patients, multiple biliary calculi, complicated by biliary stricture, were found in the inferior branch of left lateral bile duct via preoperative cholangiography. After the choledochoscopic cholelithotomy, the combination of absolute ethanol and N-butyl-cyanoacrylate were injected into the diseased biliary duct lumen. Two months later, their T-tube cholangiography demonstrated that the targeted biliary ducts were completely embolized, thus effectively preventing the calculous recurrence. Twelve and 15 months later, their computed tomography scan showed that the inferior segments of left lateral lobes were almost completely atrophied and disappeared, thus successfully achieving the chemical "resection" of the diseased hepatic lobe. Chemical bile duct embolization may be a feasible and safe technique to prevent the calculous recurrence and concurrently achieve the effect of chemical hepatectomy for highly selected hepatolithiasis cases.

Abstract
PURPOSE To review the current state of evaluation and management of various forms of endophthalmitis. METHODS A review of the literature is included, encompassing endophthalmitis occurring after ocular surgeries, intravitreal injection, trauma, and systemic infection. Based on this review, current principles and techniques for evaluating and treating these forms of endophthalmitis are discussed. RESULTS Postoperative endophthalmitis after cataract surgery is the most common presentation. Conclusions from the Endophthalmitis Vitrectomy Study (EVS) remain a foundation for management of postcataract surgery endophthalmitis, notably prompt intravitreal antibiotic administration after vitreous sampling, with consideration for pars plana vitrectomy in severe cases. The potential impact of advances since the EVS, such as oral fourth generation fluoroquinolones and new vitrectomy techniques, are also discussed. The management of postcataract endophthalmitis is compared and contrasted to endophthalmitis occurring after other ocular surgeries, intravitreal injection, trauma, and systemic infection. Although some principles remain common, treatment rationales differ with other forms of endophthalmitis based on differing clinical circumstances, such as the virulence of organisms that are frequently encountered. CONCLUSIONS Endophthalmitis is a serious, potentially vision threatening condition which can present in various settings. Prompt recognition and treatment are key in maximizing outcomes.

Abstract
BACKGROUND Bile leakage remains a major postoperative complication after liver resection. Bile leakage after hepatectomy for liver neoplasms has been well studied. However, the risk factors and management of this complication after liver resection for intrahepatic lithiasis has not been investigated. METHODS From January 1992 to June 2004, 312 consecutive patients with intrahepatic lithiasis underwent hepatic resections Sun Yet-san University. Perioperative risk factors pertaining to the development of bile leakage were identified using univariate and multivariate analysis. The management and outcome of these patients with bile leakage were evaluated. RESULTS Bile leakage developed in 23 (7.4%) of 312 patients. The multivariate logistic regression analysis identified that left hepatectomy (P=.024, odds ratio [OR]=3.695, 95% confidence interval [CI]: 1.185 to 11.517) and the period greater than 1 month between operative time and the latest acute cholangitis attack (P=.02, OR=4.144, 95% CI: 1.248 to 13.757) were the independent risk factors for development of bile leakage after hepatectomy for hepatolithiasis. The septic complications were higher in the patients with bile leakage than in those without bile leakage (ie, wound infection: 56.5% vs 13.5%, P=.001; subphrenic abscess: 21.7% vs 4.8%, P=.01; septicemia: 8.7% vs 0.7%, P=.029). Percutaneous drainage or combined endoscopic naso-biliary drainage was the first choice of treatment for bile leakage; 20 (87.0%) of 23 patients were treated by this method. One patient underwent re-operation for diffuse peritonitis due to withdrawal of T tube inadvertently at postoperative day 1. Two patients with bile leakage were re-operated due to uncontrollable hemobilia at postoperative day 5 and 12, respectively. CONCLUSIONS Patients who underwent hepatectomy at the period less than 1 month after the latest attack of acute cholangitis carry high risk for the development of bile leakage. Preoperative cholangiography to identify the aberrant hepatic duct for high risk patients and avoidance of hepatectomy at the acute phase of cholangitis are of critical importance to prevent bile leakage after hepatectomy. Percutaneous drainage is the primary and effective treatment for bile leakage.

Abstract
Hepatolithiasis associated with cholangiocellular carcinoma is occasionally a calcium bilirubinate stone. Primary cholesterol hepatolithiasis associated with cholangiocellular carcinoma is rare; only 6 cases have been reported in the literature. A 55-year-old man was admitted to our hospital because of an elevated level of carbohydrate antigen 19-9. Various imaging studies demonstrated a mass in the segment VII of the liver. The patient underwent a curative surgical operation. Histopathological examination revealed that it was cholangiocellular carcinoma located in the periphery of the liver. A cholesterol stone was present, encircled by the cholangiocellular carcinoma. Minor inflammatory changes were observed around the stone.

Abstract
Secondary sclerosing cholangitis (SSC) is a disease that is morphologically similar to primary sclerosing cholangitis (PSC) but that originates from a known pathological process. Its clinical and cholangiographic features may mimic PSC, yet its natural history may be more favorable if recognition is prompt and appropriate therapy is introduced. Thus, the diagnosis of PSC requires the exclusion of secondary causes of sclerosing cholangitis and recognition of associated conditions that may potentially imitate its classic cholangiographic features. Well-described causes of SSC include intraductal stone disease, surgical or blunt abdominal trauma, intra-arterial chemotherapy, and recurrent pancreatitis. However, a wide variety of other associations have been reported recently, including autoimmune pancreatitis, portal biliopathy, eosinophillic and/or mast cell cholangitis, hepatic inflammatory pseudotumor, recurrent pyogenic cholangitis, primary immune deficiency, and AIDS-related cholangiopathy. This article offers a comprehensive review of SSC.

Abstract
INTRODUCTION The aim of this study was to assess the safety and the efficacy of hepatic resective surgery in the treatment of single lobe hepatolithiasis. PATIENTS AND METHODS Retrospective analysis and comparison between hepatic resections in patients with hepatolithiasis (hepatolithiasis group [HG]) and liver masses (control group [CG]). Seventeen consecutive Caucasian patients with single lobe hepatolithiasis (HG) and 30 patients with liver masses without chronic liver disease and previous chemotherapy (CG), were operated during the 5-year period 2000-2005, inclusive. Major hepatic resections including 4 right hepatectomies, 10 left hepatectomies, and 3 left lateral sectionectomy in HG, and 12 right hepatectomies, 3 extended right hepatectomy, 5 left hepatectomies, 4 left lateral sectionectomy, 5 bisegmentectomy, and 1 mesohepatectomy in CG. The main outcome measures were: type and length of surgical procedures, intra- and postoperative blood losses and transfusions (packed red blood cells [PRBC] and fresh frozen plasma [FFP]), intra- and postoperative course and complications (within 30 days of the operation), length of hospitalisation, histopathology, and recurrence of hepatolithiasis. RESULTS Mean operation time was 6.21 +/- 2.38 h in HG versus 7.10 +/- 2.21 h in CG (P = 0.33). Mean intra-operative blood loss in CG was higher than in HG (1010 +/- 550 ml versus 560 +/- 459 ml; P = 0.035). The other variables considered in the two groups were not statistically different. Intra-operative transfusion were 0.50 +/- 0.85 units in HG versus 1.35 +/- 2.25 units of PRBC in CG (P = 0.06), and 0.66 +/- 1.34 units in HG versus 0.68 +/- 1.20 units of FFP in CG (P = 0.44), respectively. No cases of death were registered. Postoperative complications occurred in 12 patients (25.5%) - 5 cases (10.6%) in HG and 7 cases (14.8%) in CG (P = 0.18). Mean postoperative transfusions were 0.47 +/- 1.24 units in HG versus 1.10 +/- 1.18 units of PRBC in CG (P = 0.35), and 0.65 +/- 1.40 units in HG versus 0.46 +/- 0.82 units of FFP in CG (P = 0.25), respectively. Difference in median hospitalisation was not statistically significant (14 +/- 10 days versus 12 +/- 9 days; P = 0.28). Histopathology showed cholangiocarcinoma in 2 cases (11.7%). During the follow-up period (range, 5-127 months; mean, 50.4 +/- 41.9 months), 1 patient had lithiasis recurrence and 1 patient died for the co-existing cholangiocarcinoma. CONCLUSIONS Hepatic resection is the treatment of choice in patients with single lobe hepatolithiasis. An early indication for surgery may reduce the mortality/morbidity rates of hepatic resection for hepatolithiasis.

Abstract
AIM: To evaluate the long-term outcome and surgical indications of hepaticojejunostomy (HJ) for the treatment of hepatolithiasis.
METHODS: Three hundred and fourteen elective cases with hepatolithiasis but without biliary stricture or cystic dilatation treated in the past 10 years were reviewed retrospectively. The patients were divided into HJ group and T tube drainage group according to biliary drainage procedure. Furthermore, four subgroups were subdivided by hepatectomy as a balance factor, group A1: hepatectomy+HJ; group A2: choledochoctomy+HJ; group B1: hepatectomy + choledochoctomy T tube drainage; group B2: choledochoctomy + T tube drainage. The stone residual rate, surgical efficacy and long-term outcome were compared among different procedures.
RESULTS: There was no surgical mortality among all patients. The total hospital mortality was 1.6%. The overall stone residual rate after surgical clearance was 25.9%. There was no statistical difference between HJ group and T tube drainage group in terms of stone residual rate after surgical clearance, however, after postoperative choledochoscopic lithotripsy, the total stone residual rate of T tube drainage group was significantly lower than that of HJ group (0.5% vs 16.7%, P < 0.01). Hepatectomy + choledochoctomy tube drainage achieved the optimal therapeutic effect, only 8.2% patients suffered from an attack of cholangitis postoperatively, which was significantly lower than that of hepatectomy + HJ (8.2% vs 22.0%, P = 0.034). The major reason for postoperative cholangitis was stone residual in the HJ group (16/23, 70.0%), and stone recurrence in the T tube drainage group (34/35, 97.1%). The operative times were significantly prolonged in those undergoing HJ, and the operative morbidity of HJ was higher than those of T tube drainage.
CONCLUSION: The treatment result of HJ for hepatolithiasis is not satisfactory in this retrospective study due to high rate of stone residual and postoperative cholangitis. HJ could not drain residual stone effectively. HJ may hinder post-operative choledochoscopic lithotripsy, which is the optimal management for postoperative residual stone. The indications of HJ for hepatolithiasis should be strictly selected.

Abstract
BACKGROUND The high recurrence rate of hepatolithiasis is still a problem to be solved. The purpose of the present study was therefore to carry out a preliminary study of the practical value of chemical bile duct embolization (CBDE) to treat hepatolithiasis in rabbits. METHODS Chemical bile duct embolization was performed with phenol or absolute ethanol along with N-butyl-cyanoacrylate. The feasibility and effectiveness of CBDE for chemical hepatectomy was assessed by investigating histological changes, biochemistry for hydroxyproline and in situ hybridization for collagen I. RESULTS Histologically, the mucosal epithelia of the embolized bile ducts were entirely replaced by collagen fibers, thus effectively eradicating chronic proliferative cholangitis. Also of note, the diseased biliary duct lumens were completely filled with N-butyl-cyanoacrylate, thus effectively preventing calculus formation. The hepatocytes also disappeared completely in the periphery of the embolized lobe, demonstrating that the desired effects of chemical hepatectomy were achieved through CBDE. In a further comparison of embolizing agents, the phenol-cyanoacrylate embolized livers and bile ducts had a higher level of hydroxyproline and collagen I than those embolized with ethanol plus cyanoacrylate. CONCLUSION Chemical bile duct embolization is a promising approach to prevent the recurrence of hepatolithiasis and to achieve the effect of chemical hepatectomy.

Abstract
Gallstones are common in Western countries and Japan. Most gallstones are found in the gallbladder, but they sometimes pass through the cystic duct into extrahepatic and/or intrahepatic bile ducts to become bile-duct stones, causing conditions known as choledocholithiasis and hepatolithiasis. Some 10-15% of gallstone patients concomitantly suffer from bile-duct stones. Bile-duct stones can also be formed in the absence of gallbladder stones, and such primary bile-duct stones are more common in East Asian countries than in the Western world. Thus pathogenesis of primary and secondary bile-duct stones is unlikely to be similar. Furthermore, the gallbladder stones are primarily cholesterol or black-pigment stones, whereas most bile-duct stones are brown-pigment stones (calcium bilirubin stones). Thus, epidemiology, pathogenesis and classification of biliary stones are very likely to differ according to stone location (intrahepatic and/or extrahepatic bile duct).

Abstract
Gallstone disease is common: >700,000 cholecystectomies and costs of approximately 6.5 billion dollars annually in the U.S. The burden of disease is epidemic in American Indians (60-70%); a corresponding decrease occurs in Hispanics of mixed Indian origin. Ten to fifteen per cent of white adults in developed countries harbour gallstones. Frequency is further reduced in Black Americans, East Asia and sub-Saharan Africa. In developed countries, cholesterol gallstones predominate; 15% are black pigment. East Asians develop brown pigment stones in bile ducts, associated with biliary infection or parasites, or in intrahepatic ducts (hepatolithiasis). Certain risk factors for gallstones are immutable: female gender, increasing age and ethnicity/family (genetic traits). Others are modifiable: obesity, the metabolic syndrome, rapid weight loss, certain diseases (cirrhosis, Crohn's disease) and gallbladder stasis (from spinal cord injury or drugs like somatostatin). The only established dietary risk is a high caloric intake. Protective factors include diets containing fibre, vegetable protein, nuts, calcium, vitamin C, coffee and alcohol, plus physical activity.

Abstract
Hepatolithiasis (oriental cholangiohepatitis) has reportedly been endemic only in East Asia. The disease is now occasionally recognized in Western societies, especially in people who have lived in the Orient. Hepatolithiasis is characterized by its intractable nature and frequent recurrence, requiring multiple operative interventions, which is in distinct contrast to gallbladder stones. In addition to frequent cholangitis and chronic sepsis, it is widely known that longstanding intrahepatic stones lead to intrahepatic cholangiocarcinoma. Symptoms of hepatolithiasis include abdominal pain, jaundice and cholangitis. Pyogenic cholangitis due to strictures and hepatolithiasis tends to recur, and sometimes patients may present with liver abscesses. Radiological studies and percutaneous procedures are keys in the diagnosis and treatment of hepatolithiasis. Non-invasive imaging modalities such as ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) accurately depict the normal anatomy and presence of intrahepatic stones. It should be stressed that each modality has its pros and cons, and imaging studies should be performed on the basis of understanding the pathophysiology. As the diagnostic role of magnetic resonance cholangiopancreatography (MRCP) evolves, the roles of both endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC), and their most significant advantage, is primarily therapeutic with their ability to extract stones, biopsy intraductal lesions, and place stents easily. The primary goals of treatment are to eliminate attacks of cholangitis and to stop the progression of the disease (which leads to biliary cirrhosis). Surgery has a primary role in hepatolithiasis because hepatolithiasis tends to recur, so that multiple sessions of the endoscopic approach (i.e. two or three times a year) are often required. PTC is an alternative when surgical resection of the affected lobe is difficult. Techniques for lithotripsy, including shockwave and laser, can be applied in endoscopic sessions, offering a better chance of clearing the stones.

Abstract
BACKGROUND Hepatolithiasis is a common disease in East Asia and its aggravating factor is bile duct stenosis because of refractory cholangitis. This study investigated the feasibility of gene therapy for bile duct stenosis by administration of p53 adenoviral vectors into the bile. MATERIALS AND METHODS Adenoviral vectors (AxCALacZ or AxCAhp53) were injected transpapillarily into the bile in the bile duct in a rat model of cholangitis. The extent and duration of the gene expression was evaluated with X-gal staining and p53 immunostaining. The bile duct tissue was examined to evaluate the inhibitory effect on the proliferative changes at 3 and 7 days after administration, and Ki-67 labeling index was determined. RESULTS beta-galactosidase was expressed in the bile duct epithelia, the bile duct wall and the surrounding connective tissue. The expression of beta-galactosidase was detected at 4 weeks after the administration. Mean thickness of the bile duct wall at 7 days was 343.2 +/- 14.0 microm for the AxCAhp53 group, 446.5 +/- 25.3 microm for the AxCALacZ group and 447.1 +/- 53.4 microm for the control group. The proliferation of the bile duct wall was significantly suppressed in the AxCAhp53 group (P < 0.05). Maximum thickness was 408.0 +/- 23.9 microm for the AxCAhp53 group (P < 0.05), 650.0 +/- 49.3 microm for the AxCALacZ group, and 590.0 +/- 64.3 microm for the control group. Mean Ki-67 labeling index for the three groups was 20.7% (P < 0.05), 34.4% and 37.4%, respectively. CONCLUSIONS P53 gene transfer by administration of the adenoviral vector into the bile suppressed the proliferative changes in the bile duct in a rat cholangitis model.
