Myiasis is a parasitic infection caused by dipteran larvae settling in living tissue and organs. Infestation is generally found in tropical and rural areas, where interaction with animals is common. It is diagnosed based on the evidence of the existence of dipteran larvae in tissues and organs. When planning the treatment, identifying the type of larvae is as important as identifying the infected organ or system. In this case report, we present the case of a female who had a biliary tract injury caused by laparoscopic cholecystectomy and who developed a postoperative enterocutaneous fistula and myiasis caused by third-stage Sarcophaga sp...

Postoperative biliary leaks have become more common in the past three decades since the development of laparoscopic biliary surgery. The role of the radiologist and interventional radiologist is important in the diagnosis and treatment of such complications, and can play an adjunctive role in the definitive surgical repair. Ultrasound, computed tomography, magnetic resonance cholangiopancreatography, nuclear medicine cholescintigraphy studies, and percutaneous transhepatic cholangiograms (PTC) are the various imaging modalities used for diagnosis...

Liver plays a key role in cholesterol metabolism. Impaired hepatic cholesterol homeostasis causes intracellular free cholesterol accumulation and hepatocyte injury. Sortilin 1 (Sort1) is an intracellular lysosomal trafficking receptor that was recently identified by GWAS as a novel regulator of cholesterol metabolism in humans. Here we report that Sort1 deficiency protected against cholesterol accumulation-induced liver injury and inflammation in mice. Using LC-MS/MS based proteomics approach, we identified liver carboxyesterase 1 (CES1) as a novel Sort1 interacting protein...

INTRODUCTION: This study explored whether bacterial endotoxins, in the form of lipopolysaccharides (LPS), could have an injurious effect on the biliary tract in conjunction with ischemia. METHOD: Sixty-four rats were randomly assigned to four groups: sham operation (sham), 1mg/kg LPS i.p. (LPS), hepatic ischemia reperfusion (IR), and IR combined with LPS (IR+LPS). Following 1 or 6 hours of reperfusion, serum liver tests, bile duct histology, immunofluorescence microscopy (zonula occludens-1), bile composition (bile salts, phospholipids, lactate dehydrogenase), hepatic gene expression (bile salt transporters and inflammatory mediators) as well as serum and biliary cytokine concentrations were quantified and compared between the study groups...

Hepatic progenitor cells (HPCs) are bipotential stem cells that can differentiate into mature hepatocytes or biliary epithelial cells (BECs). They are thought to be involved in repair of liver injury and the incidence of hepatic carcinoma. Their physiology is closely associated with the microenvironment where they reside. Lipopolysaccharide (LPS), an important component of the hepatic pathological microenvironment, is stored in the liver and affects many types of cells in various hepatosis. HPCs may also be influenced by LPS...

Mirizzi syndrome is the compressive blockage of the cystic or choledochal duct caused by a biliary stone occupying the cystic canal or Hartmann's pouch. This occurrence is rare and, in English literature, three cases defined in children have been observed. In order to draw attention to this rare occurrence, we preferred a 14-year-old male patient with Mirizzi syndrome. In this case, ERCP was performed preoperatively and the diagnosis was carried out with the help of clear visualisation and identification of the tissue structures as well as the stent placed in bile duct; so we protected the patient from the possible iatrogenic injury occurring during surgery...

AIM: To evaluate the effects of melatonin (Mel) on oxidative stress in an experimental model of bile duct ligation (BDL). METHODS: Male Wistar rats (n = 32, weight ± 300 g) were allocated across four groups: CO (sham BDL), BDL (BDL surgery), CO + Mel (sham BDL and Mel administration) and BDL + Mel (BDL surgery and Mel administration). Mel was administered intraperitoneally for 2 wk, starting on postoperative day 15, at a dose of 20 mg/kg. RESULTS: Mel was effective at the different standards, reestablishing normal liver enzyme levels, reducing the hepatosomatic and splenosomatic indices, restoring lipoperoxidation and antioxidant enzyme concentrations, reducing fibrosis and inflammation, and thereby reducing liver tissue injury in the treated animals...

Chronic hepatic injury is accompanied by a ductular response that is strongly correlated with disease severity and progression of fibrosis. To investigate whether anti-inflammatory drugs can modulate the ductular response, we treated mice suffering from a steatotic or cholestatic injury with anti-TNF-α antibodies (Infliximab) or glucocorticoids (Dexamethasone). We discovered that Dexamethasone and Infliximab can both modulate the adaptive remodeling of the biliary architecture that occurs upon liver injury and limit extracellular matrix deposition...

The cystic artery is the key structure sought to be clipped or ligated during laparoscopic or conventional cholecystectomy. The possible complications like hemorrhage or hepatobiliary injury are always centered on the search, dissection, and clipping or ligation of the cystic artery, many a time because of possibility of variations in its course and relations to the biliary ducts. This descriptive study was carried out to document the normal anatomy and different variations of the cystic artery to contribute to improve surgical safety...

Bile duct injuries (BDI) tend to be more complex in laparoscopic than in open cholecystectomy procedures, and frequently involve young adults with benign pathologies. The ultimate consequence may be a liver transplantation (LT), making this situation one of the most rare transplant indications. Fatal post-transplant outcome is extreme infrequently reported. Aim of this study is to report on our single-case experience and to review the literature concerning lethal outcome after LT for major BDI following cholecystectomy...

INTRODUCTION: The incidence of liver damage due to steroid consumption is increasing due to the omnipresence of the idealized body image and the widespread availability of drugs via the Internet. The genetic factors underlying individual susceptibility are not presently known. CASE PRESENTATION: A male patient developed cholestatic liver injury two weeks after a two-month course of anabolic steroids. Next-generation sequencing (NGS) of 24 cholestasis-related genes revealed a heterozygous two-basepair deletion in exon 1 of the pregnane X receptor gene (PXR)...

Liver injury modulates local microenvironment, triggering production of signals that instruct stem cell fate choices. In this study, we employed a microfluidic co-culture system to recreate important interactions in the liver stem cell niche, those between adult hepatocytes and liver progenitor cells (LPCs). We demonstrate that pluripotent stem cell-derived LPCs choose hepatic fate when cultured next to healthy hepatocytes but begin biliary differentiation program when co-cultured with injured hepatocytes. We connect this fate selection to skewing in production of hepatocyte growth factor (HGF) and transforming growth factor (TGF)-β1 caused by injury...

Acute kidney injury (AKI) is a major complication in patients with liver disease. Although hepatorenal syndrome is frequently involved, bile cast nephropathy, characterized by tubular bile cast formation, has been scarcely described in the setting of severe liver failure. Few renal histology studies are available in these patients. We describe a case of bile cast nephropathy in a patient with obstructive cholestasis caused by stones in the common bile duct. The kidney biopsy confirmed this diagnosis, with several green casts in tubular lumens, tubular injury, and bilirubin composition of the tubular casts with Hall stain...

The liver biopsy guides diagnostic investigation and therapy in infants with undiagnosed cholestasis. Histologic features in the liver may also have prognostic value in the patient with biliary atresia (BA). We assessed the relative value of histologic features in 227 liver needle biopsies in discriminating between BA and other cholestatic disorders in infants enrolled in a prospective Childhood Liver Disease Research Network (ChiLDReN) cohort study by correlating histology with clinical findings in infants with and without BA...

Cholestasis is a condition that leads to chronic hepatobiliary inflammation, fibrosis, and eventually cirrhosis. Many microRNAs (miRs) are known to have a role in fibrosis progression; however, the role of miR-21 during cholestasis remains unknown. Therefore, the aim of this study was to elucidate the role of miR-21 during cholestasis-induced biliary hyperplasia and hepatic fibrosis. Wild-type (WT) and miR-21(-/-) mice underwent Sham or bile duct ligation (BDL) for 1 week, before evaluating liver histology, biliary proliferation, hepatic stellate cell (HSC) activation, fibrotic response, and small mothers against decapentaplegic 7 (Smad-7) expression...

IgG4-related disease (IgG4-RD) is a fibroinflammatory condition that can affect practically every organ. Although it was first identified in pancreas and salivary glands, major organs like liver, biliary tree, kidney, thyroid glands and lungs are commonly involved, sometimes resulting in organ failure. We describe a case of an 41-year-old man presented with back pain after a rotator cuff injury. A Computed Tomography (CT) revealed incidentally a right lower lobe paravertebral lesion extending across the T5 and T6 vertebral levels and invading into the adjacent pleural surface...
