BACKGROUND: Pediatric living donor liver transplantation is associated with slight alteration in cardiac enzymes without ongoing acute cardiac injury, but available information about the significance of these changes is limited. The aims of this study were to analyze the link between the anomalies of intraoperative serum cardiac troponin I (cTnI) and acute lung injury during the first week after liver transplantation. METHODS: In this retrospective study, 123 children suffered from biliary atresia were enrolled...

Regulatory T cells (Tregs) and CD4(+) T helper (Th) cells have important roles in bile duct injury of biliary atresia (BA). However, their impacts on liver fibrosis are undefined. Between 2013 and 2016, 146 patients with various stages of BA were enrolled in this study. Peripheral blood, liver biopsy and lymph node samples were collected. Flow cytometry, magnetic cell sorting and immunostaining were used to characterize lymphocytes from BA patients. Deficiency of Tregs was observed along with increased Th1, Th2 and Th17 frequencies in the peripheral blood and livers of BA patients...

Tissue repair is orchestrated by a finely tuned interplay between processes of regeneration, inflammation and cell protection, allowing organisms to restore their integrity after partial loss of cells or organs. An important, although largely unexplored feature is that after injury and during liver repair, liver functions have to be maintained to fulfill the peripheral demand. This is particularly critical for bile secretion, which has to be finely modulated in order to preserve liver parenchyma from bile-induced injury...

Autoimmune liver diseases are a group of abnormal autoimmune-mediated inflammatory hepatobiliary injuries, mainly including autoimmune hepatitis(AIH), primary biliary cholangitis(PBC), and primary sclerosing cholangitis (PSC). The diagnosis and treatment of autoimmune liver diseases, an important type of non-viral liver disease, have become a prominent issue in hepatology. In 2016, many new advances have been achieved in the clinical and basic research on autoimmune liver diseases, including the phase 3 clinical trial of obeticholic acid, the proposal of UK-PBC risk score, and the research on gut microbiota associated with PSC...

Biliary atresia is an obstructive cholangiopathy of infancy that progresses to end-stage cirrhosis. Although the pathogenesis of the disease is not completely understood, previous reports link TNFα to apoptosis of the bile duct epithelium in the presence of IFNγ. Here, we investigate if TNFα signaling regulates pathogenic mechanisms of biliary atresia. First, we quantified the expression of TNFA and its receptors TNFR1 and TNFR2 in human livers and found an increased expression of the receptors at the time of diagnosis...

Benign biliary strictures (BBSs) are commonly caused by surgical injury, chronic pancreatitis, and inflammatory cholangiopathies. Although advanced imaging tests and tissue acquisition methods have been developed for evaluation of indeterminate biliary strictures, differentiation of BBSs from biliary malignancies remains a challenge to clinicians. The majority of BBSs have good response to nonsurgical treatment and surgical intervention mainly serves as a rescue when nonsurgical approaches fail. Endoscopic management is a safe, effective, and less-invasive treatment for BBSs compared with other approaches...

BACKGROUND MR cholangiopancreatography is widely performed before laparoscopic cholecystectomy to rule out choledocholithiasis and to avoid iatrogenic injuries that may be related to the high frequency of anatomical variations of the biliary tree. Although most of these variants have already been demonstrated surgically and by endoscopic retrograde cholangiopancreatography and CT cholangiography, there are no references in which MR cholangiopancreatography has shown a cystic duct draining into the right hepatic biliary duct...

BACKGROUND: Imaging techniques that enhance visualisation of the anatomy may help prevent bile duct injury. Near-Infrared Fluorescence Imaging is such a technique. Previous experiments with ICG have shown that illumination of the extra-hepatic bile ducts is feasible. Yet, there is room for improvement in the visualisation of the target as compared to the background. Experiments with IRDye(®) 800CW show promising results. However, this dye is too expensive for routine clinical use. The aim of this study is to test the first applicability of two newly developed preclinical dyes regarding intraoperative imaging of the cystic duct and cystic artery, compared with IRDye(®) 800CW...

Apoptosis induced by the bile acids in the liver is considered to play a pivotal role in the pathogenesis of cholestatic disease. Increasing evidence has demonstrated that Paeoniflorin (PF) exerts therapeutic effect on severe cholestatic liver diseases. However, whether PF could protect against alpha-naphthylisothiocyanate (ANIT)-induced cholestasis by inhibiting apoptosis remains unclear. In this study, we mainly investigated the effect and anti-apoptosis mechanism of PF on cholestasis. Experimental results indicated that PF pretreatment could attenuate liver damage and cholestasis by ANIT in rats, lift the biliary excretion in addition to decrease serum indices (ALT, AST, DBIL, TBIL, TBA, ALP and ϒ-GT) and conspicuous neutrophil infiltration and cell apoptosis in liver evidenced by TUNEL staining...

The sequelae of cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) in organ donors potentially results in ischemic organ injury and graft dysfunction after transplantation. Thresholds of resuscitation times in brain dead liver donors have not been established so far. We report the case of a brain dead liver donor who experienced 2.5 hours of CPR whose liver was successfully transplanted. A 75-year-old male experienced CA and was treated by CPR with streptokinase application for 2.5 hours until stabilization of cardiac function...

Traumatic neuromas of the biliary tract have occasionally been reported to cause strictures at the cystic duct stump as a late complication of cholecystectomy with common bile duct exploration. The incidence of symptomatic traumatic biliary neuroma appears to be low after orthotopic liver transplant, as only 25 patients have been described previously in the English-language literature. Traumatic (amputation) neuroma is a reactive proliferation of pericholangial nerve fibers induced by injury, but it is not a true neoplasm...

The liver has a highly regenerative capacity. In the normal liver, hepatocytes proliferate to restore lost liver mass.However, when hepatocyte proliferation is impaired, biliary epithelial cells (BECs) activate and contribute to hepatocytes. We previously reported in zebrafish that upon severe hepatocyte ablation, BECs extensively contribute to regenerated hepatocytes. It was also speculated that BECdriven liver regeneration might occur in another zebrafish liver injury model in which temporary knockdown of the mitochondrial import gene <i>tomm22</i> by morpholino antisense oligonucleotides (MO) induces hepatocyte death...

A duplicate gall bladder was diagnosed at laparoscopy, having been erroneously diagnosed on ultrasonography as a dilated common bile duct with choledocholithiasis. Gallbladder duplication is a congenital abnormality with a rare incidence, occuring in approximately 1 in 4 000 births and 0.020% in al large autopsy series. This report highlights its existence to improve awareness and lessen the potential for biliary injury.

BACKGROUND: Laparoscopic cholecystectomy (LC) is a common surgical procedure performed for symptomatic gallstones. There is a trend towards early cholecystectomy for patients with acute cholecystitis who present timeously. Local inflammation has been identified as a risk factor for bile duct injuries. This study sought to assess the outcomes of LC in patients managed within a resource constrained environment where late presentation is common. METHOD: We performed a retrospective analysis of laparoscopic cholecystectomy performed from January 2010 to June 2011...

Laparoscopic cholecystectomy (LC) is the preferred and most widely used method for removal of the gallbladder in patients with symptomatic cholelithiasis. Modern laparoscopic equipment provides better illumination and definition with the most recent generation processors and cameras offering the possibility of 3D visualization. The minimal access approach results in smaller wounds, less postoperative pain, faster recovery, shorter hospital stay and ultimately a better cosmetic result.1 The major disadvantage of LC, however, is the biliary complications associated with the procedure, the most serious of which is a major bile duct injury (BDI)...

Sclerosing cholangitides represent a group of chronic biliary obstructive diseases which include primary sclerosing cholangitis (PSC), IgG4 associated sclerosing cholangitis (IgG4-SC) and secondary sclerosing cholangitis (SSC). The manifestations of the diseases are similar, but their asymptomatic course is also frequent. IgG4-SC belongs to the group of IgG4 associated diseases and it is the most frequently related to type 1 autoimmune pancreatitis. Diagnosing of IgG4-SC is based on typical histopathological images, shape changes revealed by diagnostic imaging, serological tests, concurrent impairment of other organs and response to therapy, where IgG4-SC responds well to treatment with corticoids, whereas the only possibility for the remaining units is endoscopic intervention or liver transplantation...

Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG). However, the dynamic process and mechanism of fluorescence IOC have not been elucidated in previous publications. Herein, the optical properties of the complex of ICG and bile, dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated. The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration...
