Clinical practice guideline on the use of single-operator cholangioscopy in the diagnosis of indeterminate biliary stricture and the treatment of difficult biliary stones.

Background And Aims: Single-operator cholangioscopy (SOC) offer a diagnostic and therapeutic alternative with an improved optical resolution over conventional techniques; however, there are no standardized clinical practice guidelines for this technology. This evidence-based guideline from the Colombian Association of Digestive Endoscopy (ACED) intends to support patients, clinicians, and others in decisions about using in adults the SOC compared to endoscopic retrograde cholangiopancreatography (ERCP), to diagnose indeterminate biliary stricture and to manage difficult biliary stones.

Methods: ACED created a multidisciplinary guideline panel balanced to minimize potential bias from conflicts of interest.

Impact of the COVID-19 pandemic on digestive endoscopists: an Ibero-American study.

Introduction: the COVID-19 pandemic has seriously affected the world population, and has put health personnel in the spotlight as they are tasked with its management. Given their important role in the current health crisis, physicians have been heavily affected in terms of their professional practice, financial conditions and physical and mental health. The objective of this study was to determine the consequences of the COVID-19 pandemic for Colombian endoscopists and compare the effects on endoscopists from South America and from Spain.
