Advances in Diagnosis and Treatment With Cholangiopancreatoscopy

Digestive Endoscopy, Volume 38, Issue 4, April 2026.
ABSTRACT Endoscopic retrograde cholangiopancreatography (ERCP) remains the standard for diagnosing and treating pancreatobiliary diseases. Although non‐invasive imaging modalities have significantly improved, ERCP continues to play an indispensable role in clinical practice. However, ERCP has inherent limitations. Diagnostic challenges persist in cases

Intravascular Lithotripsy to Facilitate Extraction of Very Old Cardiac Implantable Electronic Devices Leads

Journal of Cardiovascular Electrophysiology, Volume 37, Issue 4, Page 752-757, April 2026.
ABSTRACT Background One of the challenges encountered when extracting transvenous leads with long dwell times is the presence of dense calcifications encasing the leads. This is the most likely reason for failure to advance a laser extraction sheath.

Coexistence of multiple ureteral and ureterocele stones in a patient

African Journal of Urology, 2020
Background Uroterocele causes atony and stagnation in the ureter, thus predisposing the patient to stone formation. Multiple calculi in uroteroceles are common in adults but very rare in children.

Prevention of stone migration with the Accordion during endoscopic ureteral lithotripsy. [PDF]

, 2012
BACKGROUND AND PURPOSE: Endoscopic lithotripsy is often prolonged secondary to the retrograde migration of calculous fragments. Various balloons, baskets, and other devices have been used to prevent this migration. Our purpose is to analyze the effect of

A Prospective, Multicenter, Open Label Study Investigating the Implementation of a Standardized Algorithm for Coronary CaLcificatiOn With PlaquE Modification Using UltraSound Guidance to Improve Procedural and Clinical Outcomes (CYCLOPES): Design and Rationale of the CYCLOPES Trial

Catheterization and Cardiovascular Interventions, Volume 107, Issue 4, Page 1018-1026, March 1, 2026.
ABSTRACT Introduction Moderate‐to‐severe calcification is present in ~20%–30% of patients undergoing coronary angiography. Coronary lesion modification is often necessary to facilitate optimal stent delivery and expansion, with several dedicated devices now approved for calcium modification before stent implantation. The CYCLOPES study aims to evaluate

Duodenal Ulceration following Holmium Laser Lithotripsy [PDF]

Case Reports in Gastroenterology, 2019
The epidemiology of peptic ulcer disease (PUD) has changed considerably in the last several decades. Previously a chronic disease characterized by frequent recurrences with a high rate of surgical interventions, it is now largely a self-limited disease that is medically managed.
