AI Article Synopsis
- The study focused on the incidence and characteristics of cholangitis in patients with biliary atresia after undergoing Kasai portoenterostomy (KPE).
- Among 160 patients, 78.8% experienced cholangitis, with a cumulative incidence of 75.5% at one year and 84.2% at five years post-surgery.
- The research identified Enterococcus faecium as the most common pathogen and highlighted issues with antimicrobial susceptibility, suggesting the need for tailored antibiotic therapy.
Article Abstract
Objectives: We investigated the incidence and characteristics of cholangitis after Kasai portoenterostomy (KPE) in patients with biliary atresia. We also examined the distribution and antimicrobial susceptibility patterns of the causative pathogens, which were isolated in sterile specimens, such as blood and ascites.
Methods: A retrospective chart review was performed in patients with biliary atresia who underwent KPE at Severance Children's Hospital in Korea from 2006 to 2015. The Kaplan-Meier method was used to assess the cumulative incidence of cholangitis.
Results: Among the 160 included patients, there were 494 episodes of cholangitis in 126 patients (78.8%) during the study period. The cumulative incidence of cholangitis at 1 and 5 years after KPE was 75.5% and 84.2%, respectively, and cholangitis recurred in most cases (76.2%). The cumulative incidence of culture-proven cholangitis at 1 and 5 years after KPE was 22.1% and 23.9%, respectively. Enterococcus faecium (27.7%) was the most prevalent pathogen, followed by Escherichia coli (14.9%), Enterobacter cloacae (10.6%), and Klebsiella pneumoniae (8.5%). Gram-positive isolates (n = 19) showed low susceptibility to ampicillin (42.1%) and gentamicin (66.7%), and only 38.1% of Gram-negative isolates (n = 21) were susceptible to cefotaxime.
Conclusions: The present study is the largest to show the high incidence and characteristics of cholangitis after KPE in patients with biliary atresia. Enterococcus is a common pathogen of cholangitis after KPE and should be considered when choosing empiric antimicrobial therapy.

Lymph node sampling with endoscopic ultrasound fine needle aspiration (EUS-FNA) may affect treatment options for biliary tract cancers. Our aim is to clarify its utility and clinical significance and the factors associated with FNA cytology positivity. Seventy-one consecutive patients with biliary tract cancer who underwent EUS-FNA to diagnose lymphadenopathies from April 2012 to July 2021 were enrolled retrospectively.

Background: Most patients undergoing pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) develop recurrence. No previous studies have investigated predictors of local-only recurrence following PD for PDAC. Our study aimed to determine timing, pattern and predictors of any-site and local-only recurrence following PD for PDAC.

Background: Cyst size, its growth rate, and diameter of the main pancreatic duct (MPD) are all associated with pancreatic carcinoma prevalence in intraductal papillary mucinous neoplasms (IPMNs).
Objective: To examine the above factors in relation to future risk of incident pancreatic carcinoma in individuals with IPMNs harbouring no high-risk stigmata.
Design: In a prospective longitudinal cohort, we analysed 2549 patients with IPMNs.

Purpose: To determine the characteristic changes of peripheral blood T cells and identify potential biomarkers that associated with the clinical efficacy of combined immunotherapy and anti-angiogenic therapy in patients with advanced squamous non-small cell lung cancer (NSCLC).
Methods: We performed a comprehensive immunological assessment of peripheral blood mononuclear cell samples from advanced squamous NSCLC patients before and after combination of immunotherapy (Camrelizumab) and anti-angiogenic therapy (Apatinib) using spectral flow cytometry. Correlations between these immunological features and clinical efficacy were analyzed.

Background And Aim: Although long self-expandable metal stent (SEMS) with a sufficient intragastric portion is typically preferred for endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS), this design can complicate endoscopic re-intervention for recurrent biliary obstruction (RBO). We evaluated the efficacy and safety of endoscopic re-intervention for RBO through the stent after EUS-HGS using a novel partially covered SEMS with an anchoring flange.
Methods: The partially covered SEMS was designed with a intrahepatic uncovered portion measuring 1.
