The Role of Peroral Cholangioscopy in Evaluating Indeterminate Biliary Strictures [PDF]

, 2019
Biliary strictures are considered indeterminate when the initial radiologic evaluation and endoscopic retrograde cholangiopancreatography with brush cytology and/or forceps biopsy do not reveal diagnostic findings.

Single-operator holmium laser lithotripsy under direct peroral cholangioscopy using an ultra-slim upper endoscope in a patient with a large stone in the common bile duct

The Turkish Journal of Gastroenterology, 2017
In patients with complicated stones (e.g., large stones) in the common bile duct (CBD), advanced treatment modalities are generally needed. Here we present an interesting case of a large CBD stone treated with holmium laser lithotripsy, which was ...

Role of peroral cholangioscopy and pancreatoscopy in the diagnosis and treatment of biliary and pancreatic disease: past, present, and future

Frontiers in Gastroenterology, 2023
Peroral cholangiopancreatoscopy was described as early as the 1950s. However, the small caliber of these ducts and the technological limitations in developing slender, maneuverable, high-definition scopes posed a challenge.

Staging cholangiocarcinoma by cholangioscopy [PDF]

, 2008
Peroral cholangioscopy (POCS) and percutaneous transhepatic cholangioscopy (PTCS) were first developed in the 1970s, and technical developments and clinical applications have taken place gradually ever since.

The Role of Cholangioscopy and EUS in the Evaluation of Indeterminate Biliary Strictures

Gastroenterology Insights, 2022
Bile duct stenosis continues to present a diagnostic dilemma for clinicians. It is important to establish the benign or malignant nature of the stricture early in order to avoid any unnecessary delay in medical treatment or surgery.

Clinical Evaluation of the Effectiveness of Digital Peroral Cholangioscopy‐Guided Lithotripsy for Difficult Bile Duct Stones

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background and Aims Peroral cholangioscopy‐guided lithotripsy (POCS‐L) has emerged as a treatment option for difficult bile duct stones (DBDSs), but detailed evidence remains limited. This study evaluated its effectiveness, safety, and risk factors for adverse events (AEs).

Visceral Adipose Tissue as an Independent Predictor of Severe Post‐ERCP Pancreatitis: A Multicenter Retrospective Cohort Study

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background Acute pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP), known as post‐ERCP pancreatitis (PEP), is a major adverse event. Although risk factors for PEP incidence have been widely studied, factors associated with severe PEP remain unclear.

Role of Peroral Cholangioscopy in the Diagnosis of Primary Sclerosing Cholangitis

Diagnostics, 2020
Primary sclerosing cholangitis (PSC) is characterized by idiopathic biliary stricture followed by progressive cholestasis and fibrosis. When diagnosing PSC, its differentiation from other types of sclerosing cholangitis and cholangiocarcinoma is ...

Two Contrasting Scintigraphy‐Negative Pediatric Meckel's Diverticula Identified and Localized by Intestinal Ultrasound and Double‐Balloon Enteroscopy: A Report of Two Cases

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Scintigraphy‐negative Meckel's diverticulum (MD) is diagnostically challenging in children, particularly when the underlying pathology differs between cases. Technetium‐99m pertechnetate scintigraphy is widely used for diagnosis; however, false‐negative results may occur when ectopic gastric mucosa is absent or when the diverticulum is ...
