IMPORTANCE: Colorectal cancer (CRC) can compromise the mucosal barrier and subsequently allow a route for bacterial invasion into the portal system or systemic circulation. Despite preliminary data suggesting that patients who experienced pyogenic liver abscess (PLA) have higher CRC incidence rates, data from outside the Southeast Asian population are sparse. OBJECTIVE: To investigate whether there is an association between PLA and the subsequent incidence of diagnosed CRC using the Veterans Health Administration (VHA) cohort...

Background and study aims Single-operator peroral cholangioscopy (SOC) has gained increasing attention in modern biliary and pancreatic therapy and diagnosis. This procedure has shown higher rates of infectious complications than conventional endoscopic retrograde cholangiopancreatography (ERCP); therefore, many guidelines recommend antibiotic prophylaxis (AP). However, whether AP administration decreases infectious or overall adverse events (AEs) has been little studied. We aimed to study whether AP affects post-procedure infectious or overall AEs in ERCP with SOC...

BACKGROUND & AIMS: Guidelines for the management of primary biliary cholangitis (PBC) were published by the British Society of Gastroenterology in 2018. In this study, we assessed adherence to these guidelines in the UK National Health Service (NHS). METHODS: All NHS acute trusts were invited to contribute data between 1 January 2021 and 31 March 2022, assessing clinical care delivered to patients with PBC in the UK. RESULTS: We obtained data for 8,968 patients with PBC and identified substantial gaps in care across all guideline domains...

BACKGROUND: Clinical guidelines recommend that patients with long-standing ulcerative colitis (UC) should undergo periodic surveillance colonoscopy. However, the cost and clinical value of performing annual colonoscopy among high-risk patient populations is largely unknown in the Middle East. Therefore, this study aimed to examine the cost and consequence of annual colonoscopy among high-risk UC patients in Saudi Arabia. METHODS: A retrospective cohort study was conducted on UC patients who had UC for ≥ 8 years or had primary sclerosing cholangitis (PSC) at any time during their disease,and underwent colonoscopy surveillance between 2010 and 2021 at a university-affiliated tertiary care center...

In this case report, we describe a patient who was diagnosed with both Primary Biliary Cholangitis and Coeliac Disease, presenting with symptoms and signs of severe malabsorption and portal hypertension. Extensive workup was done including duodenal and liver biopsies and our patient was ultimately found to have both autoimmune diseases. An association between the two diseases has been reported multiple times during the past four decades with current guidelines recommending screening patients with primary biliary cholangitis for coeliac disease...

BACKGROUND: Acute cholangitis is a severe, life-threatening infection of the biliary system that requires early diagnosis and treatment. The Tokyo Guidelines recommend a combination of clinical, laboratory, and imaging findings for diagnosis and severity assessment, but there are still challenges in identifying severe cases that need immediate intervention. The microbiota and its derived products have been implicated in the pathogenesis of acute cholangitis. Corisin is a microbiome-derived peptide that induces cell apoptosis, acute tissue injury, and inflammation...

In response to rising concerns over multidrug resistance patterns in acute cholangitis patients, this retrospective study was conducted at the Emergency County Hospital Timisoara, Romania, encompassing patients treated between August 2020 and August 2023. The study aimed to investigate the influence of prior interventions, specifically sphincterotomy (with or without stent placement), on the current clinical and microbiological profiles of acute cholangitis patients. By differentiating between patients with a history of sphincterotomy and the endoscopic retrograde cholangiopancreatography (ERCP)-naïve, we assessed the resistance of bacterial strains to antibiotics by the Tokyo Guidelines 2018, using bile cultures from 488 patients...

INTRODUCTION: Cefmetazole (CMZ), an antibiotic with limited international distribution, is recommended by the Tokyo Guidelines 2018 (TG18) for non-severe cases of acute cholangitis (AC). However, the risk factors for CMZ-non-susceptible (CMZ-NS) bacteremia in AC remain unclear. Here, we aimed to investigate the risk factors for CMZ-NS bacteremia and evaluate mortality in patients with AC. METHODS: This single-center, retrospective, observational study included all patients diagnosed with definite bacteremic AC, based on TG18, from April 2019 to March 2023...

Longstanding inflammatory bowel disease (especially in patients with severely active disease or primary sclerosing cholangitis) is associated with an increased risk of developing dysplasia and adenocarcinoma. This review covers critical clinical aspects, such as risk factors and screening endoscopy basics, emphasising the SCENIC (Surveillance for Colorectal Endoscopic Neoplasia Detection in Inflammatory Bowel Disease International Consensus) guidelines. The histopathological and molecular features of both conventional (adenomatous) dysplasia and the non-conventional subtypes (hypermucinous dysplasia, goblet cell-deficient dysplasia, crypt cell dysplasia, serrated dysplasias) are discussed with an emphasis on challenging diagnostic areas and helpful tips to allow correct categorisation by the practising pathologist...

Cholangiocarcinoma (CCA) is the most common malignancy in patients with primary sclerosing cholangitis (PSC), accounting for 2-8% of cases and being the leading cause of death in these patients. The majority of PSC-associated CCAs (PSC-CCA) develop within the first few years after PSC diagnosis. Older age and male sex, as well as concomitant inflammatory bowel disease (IBD) or high-grade biliary stenosis, are some of the most relevant risk factors. A complex combination of molecular mechanisms involving inflammatory pathways, direct cytopathic damage, and epigenetic and genetic alterations are involved in cholangiocytes carcinogenesis...

OBJECTIVES: For preoperative biliary drainage (PBD) of malignant hilar biliary obstruction (MHBO), current guidelines recommend endoscopic nasobiliary drainage (ENBD) due to the higher risk of cholangitis after endoscopic biliary stenting (EBS) during the waiting period before surgery. However, few studies have supported this finding. Therefore, we aimed to compare the outcomes of preoperative ENBD and EBS in patients with MHBO. METHODS: Patients with MHBO who underwent laparotomy for radical surgery after ENBD or EBS were included from retrospectively collected data from 13 centers (January 2014 to December 2018)...

BACKGROUND/PURPOSE: The aim of this study was to clarify the clinical characteristics of acute cholangitis (AC) after bilioenteric anastomosis and stent-related AC in a multi-institutional retrospective study, and validate the TG18 diagnostic performance for various type of cholangitis. METHODS: We retrospectively reviewed 1079 AC patients during 2020, at 16 Tokyo Guidelines 18 (TG 18) Core Meeting institutions. Of these, the post-biliary reconstruction associated AC (PBR-AC), stent-associated AC (S-AC) and common AC (C-AC) were 228, 307, and 544, respectively...

There are no clinical guidelines for performing nephrectomy in patients with autosomal recessive polycystic kidney disease (ARPKD). Few reports have described the clinical course of ARPKD diagnosed in the neonatal period in detail. Here, we report seven patients diagnosed with ARPKD and treated at our center during the neonatal period. Two died within 48 h of life due to pulmonary hypoplasia. Of the remaining five patients, three had anuria and required for kidney replacement therapy (KRT) within one week after birth, whereas two with a milder phenotype survived without KRT...

Primary sclerosing cholangitis (PSC) is the classical hepatobiliary manifestation of inflammatory bowel disease (IBD) and a lead indication for liver transplantation (LT) in the western world. In this article, we present a Consensus Statement on LT practice, developed by a dedicated Guidelines' Taskforce of the European Society of Organ Transplantation (ESOT). The overarching goal is to provide practical guidance on commonly debated topics, including indications and timing of LT, management of bile duct stenosis in patients on the transplant waiting list, technical aspects of transplantation, immunosuppressive strategies post-transplant, timing and extension of intestinal resection and futility criteria for re-transplantation...

BACKGROUND AND AIMS: The Swiss Autoimmune Hepatitis Cohort Study is a nationwide registry, initiated in 2017, that collects retrospective and prospective clinical data and biological samples from patients of all ages with autoimmune hepatitis treated at Swiss hepatology centres. Here, we report the analysis of the first 5 years of registry data. RESULTS: A total of 291 patients with autoimmune hepatitis have been enrolled, 30 of whom were diagnosed before 18 years of age and composed the paediatric cohort...

BACKGROUND: Choledochal cysts (CC) are cystic dilatations of the biliary tract, usually diagnosed during childhood, with an estimated incidence in the general population of 1:100000. Complications related to CC include rupture, biliary obstruction, and cholangitis. Maternal CC in pregnancy are rarely reported, and there are no guidelines on optimal management. AIM: To systematically review maternal CC diagnosed during pregnancy or postpartum with regard to the clinical presentation of CC, the mode of treatment and delivery, and maternal outcomes...

BACKGROUND: This study evaluated the predictive value of different laboratory indicators for the severity of acute cholangitis (AC) according to the 2018 Tokyo Guidelines. OBJECTIVES: We enrolled consecutive patients with a diagnosis of AC from June 2016 to May 2021. Serum procalcitonin (PCT) and C-reactive protein (CRP) levels, white blood cell counts, the neutrophil-lymphocyte ratio, and the platelet-lymphocyte ratio (PLR) were compared according to the severity of AC...

OBJECTIVES: This study aimed to evaluate the current clinical practice of Dutch pediatric gastroenterologists regarding the surveillance for colorectal dysplasia and cancer in pediatric ulcerative colitis (UC), including adherence to guidelines, the initiation and interval of surveillance and applied endoscopy techniques. METHODS: A clinical vignette-based survey was distributed among all 47 pediatric gastroenterologists who are registered and working in the Netherlands...

BACKGROUND: Acute cholangitis is a severe inflammatory disease associated with an infection of the biliary system, which can lead to complications and adverse outcomes. The existing nomogram-based risk assessment methods largely rely on a limited set of clinical features and laboratory indicators, and are mostly constructed using univariable models, which have limitations in predicting the severity. This study aims to develop a nomogram-based model that integrates multiple variables to improve risk prediction for acute cholangitis...
