Abstract Background The aim of this study was to propose a novel, comprehensive, macroscopic classification for bile duct lesions. Methods A two-stage protocol designed. In Stage I, retrospective (September 2013 September 2015) patients with lesions detected by peroral cholangioscopy (POCS) performed. total 315 images at least 6 months follow-up were recorded, analyzed, and correlated histology, classified as non-neoplastic (one three types, 1 – 3) or neoplastic four 4) based on...

Background /aims: Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) has emerged as an alternative for the local treatment of unresectable pancreatic ductal adenocarcinoma (PDAC). We aim to assess feasibility and safety EUS-RFA in patients with PDAC. Methods The following was a historic cohort compounded by locally advanced (LA) metastatic (m) PDAC naïve patients, who underwent between October 2019 March 2022. performed 19-g needle electrode 10 mm active tip energy delivery....

Background and study aims The aim of this was to evaluate the diagnostic yield endoscopy using optical enhancement (OE system) with magnification predict reflux in non-erosive disease (NERD) patients. Patients methods A prospective, non-randomized, single-blind performed from September 2015 January 2016. Participants suffered gastroesophageal (GERD) symptoms were assigned NERD group or non-reflux control based on endoscopic findings a 24-hour pH-impedance-monitoring test. Endoscopy OE system...

Abstract Background and aims Irritable bowel syndrome (IBS) is considered to be a functional disease, but recent data indicate measurable organic alterations. We aimed determine the presence of colorectal mucosa microinflammation in vivo via probe-confocal laser endomicroscopy (pCLE) histological evaluation IBS patients. Methods This was prospective, controlled, nonrandomized single-blind diagnostic trial performed tertiary institution. pCLE images targeted biopsy each colon segment obtained...

BACKGROUNDAccurate detection of gastric infection by Helicobacter pylori and premalignant lesions are important for effective provision treatment, preventing the development neoplasia.Optical enhancement systems with optical magnification improved identification mucosal superficial vascular patterns in patients dyspepsia. AIMTo evaluate an system high-definition magnification, diagnosis normal mucosa, pylori-associated gastritis, atrophy.

Aims ERCP stands as the primary choice for treating pancreatobiliary disorders. Among its complications, post-ERCP pancreatitis (PEP) is most frequent, with a prevalence ranging from 4-10%, and reaching up to 15% in high-risk patients. To mitigate hydrostatic pressure contributing PEP patients, insertion of pancreatic duct stent considered preventive measure. The available options stenting include plastic stents (PPS) biodegradable (BDS) placement; However, currently, there no data on their...

Aims Percutaneous liver biopsy (PC-LB) is the gold standard for study of chronic disease. However, it limited to patients with appropriate clinical and hematological conditions. Transjugular (TJ-LB) represents a less invasive yet available technique. Endoscopic ultrasound-guided (EUS-LB) has emerged as minimally readily To best our knowledge, no network meta-analysis compared LB quality related adverse events among these techniques.

Aims Digital single-operator cholangioscopy (DSOC) stands as an invaluable diagnostic and therapeutic instrument, offering direct visualization of the biliary ducts. The use cholangioscopes with higher diameter may raise concerns regarding patient discomfort safety. Smaller could offer enhanced maneuverability decreased risk adverse events, improving procedural success rates. aim this study is to compare impact cholangioscope variation on outcomes, a focus procedure

Background and study aims Probe-based confocal laser endomicroscopy (pCLE) can provide high magnification to evaluate chronic atrophic gastritis (CAG), but the current pCLE criteria are qualitative prone variability. We aimed propose a quantitative CAG criterion based on distinguish non-atrophic (NAG) from CAG. Patients methods This observational, exploratory pilot included patients with NAG evaluated via esophagogastroduodenoscopy, pCLE, histology. measured gastric glands density, gland...

Bougies dilation is considered an effective technique for the treatment of simple benign esophageal strictures. The "rule three" has been advocated to prevent reported adverse events such as bleeding and perforation. However, adherence this rule increased cost duration treatment.To demonstrate safety long-term benefits progressive bougie dilations until reaching 15 mm (45Fr) in one single session endoscopy with non-adherence three.A retrospective analysis a prospectively collected data...

Chronic esophageal conditions (CEC) are associated with significant disease-related burden, disability, and costs. Health-related quality of life (HRQOL) constructs intended to capture the physical, mental, social, emotional aspects a patient's how health status impacts these domains. The Northwestern Esophageal Quality Life (NEQOL) can be used among diseases while maintaining sensitivity specific conditions. We aimed translate, cross-cultural adapt, validate NEQOL into Spanish.After...

Introduction: Macroscopic aspects to determine bile duct malignancy during per oral cholangioscopy (POCS) are: irregular surface with bleeding and drooling or tortuous vessels. For benign lesions, typical are lesions smooth “without vessels mass”. However, many misdiagnosis made due a lack of correlation between the macroscopic histology. Moreover, masses usually benign, reported data shows 78% sensitivity for visual impression malignancy. AIM: To propose classification tissular...

Introduction: Patients with GERD have an increased number, dilation and tortuosity of microscopic intra-papillary capillary loops (IPCLs). Recently, image-enhanced technology called Optical Enhancement system (OE systemTM) is equipped in Pentax video processor EPK-i7010. It improves visualization microvessels. Also new high definition scopes optical magnification (MagniviewTM) were developed (increase image >136 times). AIM: To evaluate diagnosis ability OE systemTM +MagniviewTM detecting...
