OBJECTIVE: This research aimed to analyze the clinical characteristics, prognosis, and antimicrobial treatment of bloodstream infections (BSI) caused by Enterobacter cloacae complex (ECC). METHODS: The clinical data of patients with bloodstream infections caused by Enterobacter cloacae complex from April 2017 to June 2023 were collected retrospectively. These data were then analyzed in subgroups based on the detection results of extended-spectrum β-lactamase (ESBL), 30-day mortality, and the type of antimicrobial agent used (β-lactam/β-lactamase inhibitor combinations (BLICs) or carbapenems)...

A 27-year-old woman with jaundice and abdominal pain was admitted to an emergency ward. The diagnostic process showed that gallstones were causing her symptoms. The patient was treated via endoscopic retrograde cholangiopancreatography (ERCP), and during the procedure she suffered a cardiac arrest. Autopsy findings included multiple pulmonary bile emboli as well as features of disseminated intravascular coagulation. Among 22 thus far described cases of bile pulmonary embolism, 13 were associated with medical procedures involving the liver and biliary tract...

BACKGROUND AND AIMS: Portal vein thrombosis (PVT) is a common complication of liver cirrhosis that can aggravate portal hypertension. However, there are features of both PVT and cirrhosis that are not recapitulated in most current animal models. In this study, we aimed to establish a stable animal model of PVT and cirrhosis, intervene with anticoagulant, and explore the related mechanism. METHODS: First, 49 male SD rats received partial portal vein ligation (PPVL), and 44 survival rats were divided into 6 groups: PPVL control group; 4-week, 6 -week, 8-week, and 10-week model group; and the rivaroxaban (RIVA)-treated group...

BACKGROUND: Assess impact of direct-acting antivirals introduction on outcomes after liver resection for hepatocellular carcinoma. METHODS: 391 patients (1991-2021) treated with resection for hepatocellular carcinoma on Hepatitis C background were divided according to receiving Hepatitis C treatment, treatment type, achievement of sustained virological response (SVR), time of resection pre- (Era 1, 1991-2011) and post-direct acting antivirals introduction (Era 2, 2012-2021)...

BACKGROUND: Endoscopic stenting is the mainstay of treatment for benign biliary strictures. There is a not-negligible rate of recurrence and stent migration. Lumen-apposing metal stents (LAMS) have a unique design with short length, large diameter and wide flanges which make them less prone to migration. AIMS: To describe the intraluminal use of LAMS to treat short benign biliary strictures. METHODS: All consecutive patients who underwent bi-flanged LAMS placement for benign biliary strictures, in approximately 6 years, were retrospectively included...

OBJECTIVE: There has been recent clinical interest in the use of vagus nerve stimulation (VNS) for treating gastrointestinal disorders as an alternative to drugs or gastric electrical stimulation. However, effectiveness of burst stimulation has not been demonstrated. We investigated the ability of bursting and continuous VNS to influence gastric and pyloric activity under a range of stimulation parameters and gastric pressures. The goals of this study were to determine which parameters could optimally excite or inhibit gastric activity...

Pethoxamid (PXA) is a chloroacetamide herbicide that works by inhibiting the germination of target weeds in crops. PXA is not a genotoxic agent, however, in a two-year chronic toxicity study, incidence of thyroid follicular cell hyperplasia was observed in male rats treated at a high dose. Many non-mutagenic chemicals, including agrochemicals are known to produce thyroid hyperplasia in rodents through a hepatic metabolizing enzyme induction mode of action (MoA). In this study, the effects of oral gavage PXA treatment at 300 mg/kg for 7 days on the disposition of intravenously (iv) administered radio-labeled thyroxine ([125 I]-T4) was assessed in bile-duct cannulated (BDC) rats...

BACKGROUND AND OBJECTIVES: The impact of dominant stricture (DS) on the outcomes of paediatric-onset primary sclerosing cholangitis (PSC) is unknown. This study was aimed at investigating the impact of DS on the clinical course and prognosis of patients with paediatric-onset PSC. METHODS: Patients with paediatric-onset PSC diagnosed between January 1993 and May 2017 were identified from hospital records or our PSC registry. Data including clinical, laboratory, cholangiography, and cytology at diagnosis and during follow-up (until July 2023) were reviewed...

A 73-year-old Japanese man with a history of distal biliary cancer treated by pancreatoduodenectomy developed pancreatic acinar cell carcinoma (PACC) treated by remnant pancreatectomy and adjuvant chemotherapy. Thirteen months after surgery, multiple liver metastases developed and FOLFOX chemotherapy was initiated. Based on the PACC diagnosis and a positive family history for breast and ovarian cancer genetic testing was performed which revealed a pathogenic germline BRCA2 variant (c.8629G > T, p...

Wilson disease is a genetic disorder of the liver characterized by excess accumulation of copper, which is found ubiquitously on earth and normally enters the human body in small amounts via the food chain. Many interesting disease details were published on the mechanistic steps, such as the generation of reactive oxygen species (ROS) and cuproptosis causing a copper dependent cell death. In the liver of patients with Wilson disease, also, increased iron deposits were found that may lead to iron-related ferroptosis responsible for phospholipid peroxidation within membranes of subcellular organelles...

Acute cholecystitis (AC), generally associated with the presence of gallstones, is a relatively frequent disease that can lead to serious complications. For these reasons, AC warrants prompt clinical diagnosis and management. There is general agreement in terms of considering early laparoscopic cholecystectomy (ELC) to be the best treatment for AC. The optimal timeframe to perform ELC is within 72 h from diagnosis, with a possible extension of up to 7-10 days from symptom onset. In the first hours or days after hospital admission, before an ELC procedure, the patient's medical management comprises fasting, intravenous fluid infusion, antimicrobial therapy, and possible administration of analgesics...

UNLABELLED: To avoid delay in oncological treatment, a 6-weeks norm for time to treatment has been agreed on in The Netherlands. However, the impact of the COVID-19 pandemic on health systems resulted in reduced capacity for regular surgical care. In this study, we investigated the impact of the COVID-19 pandemic on time to treatment in surgical oncology in The Netherlands. METHODS: A population-based analysis of data derived from five surgical audits, including patients who underwent surgery for lung cancer, colorectal cancer, upper gastro-intestinal, and hepato-pancreato-biliary (HPB) malignancies, was performed...

BACKGROUND/AIMS: The optimal length of the uncovered portion of partially covered self-expandable metal stents (PCSEMSs) used in endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) remains unclear. This study investigated the safety and efficacy of PCSEMSs with different uncovered lengths, with a focus on stent migration and time to recurrent biliary obstruction (RBO). METHODS: Outcomes of patients undergoing EUS-HGS using PCSEMSs with 5-mm and 20-mm uncovered portions at our institution from January 2016 to December 2021 were compared...

BACKGROUND: Progressive familial intrahepatic cholestasis (PFIC) is a group of autosomal recessive disorders, the most prevalent being BSEP deficiency, resulting in disrupted bile formation, cholestasis, and pruritus. Building on a previous phase 2 study, we aimed to evaluate the efficacy and safety of maralixibat-an ileal bile acid transporter inhibitor-in participants with all types of PFIC. METHODS: MARCH-PFIC was a multicentre, randomised, double-blind, placebo-controlled, phase 3 study conducted in 29 community and hospital centres across 16 countries in Europe, the Americas, and Asia...

BACKGROUND: The emergence of immune checkpoint inhibitors (ICIs) has enhanced survival outcomes for certain patients with advanced biliary tract carcinoma (BTC). Pinpointing those who would benefit most from immunotherapy remains elusive. We investigated the predictive value of the modified Gustave Roussy Immune Score (mGRIm-s) in BTC patients treated with ICIs. METHODS: Data from 110 patients at Chinese People's Liberation Army General Hospital, spanning September 2015 to April 2021, were analyzed...

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic biliary balloon dilatation (PTBD) is a challenge in resolving biliary-enteric anastomotic occlusive strictures (BEAOS) and/or coexisting stones. The biliary-enteric anastomosis (BEA) often cannot be seen because of the surgically altered gastrointestinal anatomy. Here, a technique that combined percutaneous compliant-occluded distal cholangiography and the maintenance of a large-bore catheter is described to resolve this issue...

BACKGROUND: Liver cirrhosis is the end-stage entity for a wide variety of chronic liver pathologies. These include viral hepatitis B and C, alcoholic liver disease, non-alcoholic fatty liver disease, hemochromatosis, Wilson disease, autoimmune hepatitis, primary sclerosing cholangitis, and primary biliary cirrhosis. In the majority of cases, liver cirrhosis remains completely asymptomatic until acute decompensation occurs. Patients may present complications of portal hypertension such as gastro-esophageal varices and upper digestive hemorrhage, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, or hepato-renal syndrome...

The use of indocyanine green for fluorescent cholangiography in patients with cholecystitis initially treated with percutaneous cholecystostomy drainage catheters was described in this two case series. Two patients underwent robotic assisted cholecystectomy with fluorescent cholangiography and indocyanine green through percutaneous cholecystostomy drainage catheters. The patients were diagnosed with acute cholecystitis. Directed injection of indocyanine green allowed for direct visualization of the biliary system allowing for a safe identification of the critical view of safety...
