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. Universidad de los Andes and the Colombia Grading of Recommendations Assessment, Development and Evaluation (GRADE) Network supported the guideline-development process, updating and performing systematic evidence reviews. The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients. The GRADE approach was used, including GRADE Evidence-to-Decision frameworks. RESULTS: The panel agreed on one recommendation for adult patients with indeterminate biliary strictures and one for adult patients with difficult biliary stones when comparing SOC versus ERCP. CONCLUSION: For adult patients with indeterminate biliary strictures, the panel made a conditional recommendation for SOC with stricture pattern characterization over ERCP with brushing and/or biopsy for sensitivity, specificity, and procedure success rate outcomes. For the adult patients with difficult biliary stones the panel made conditional recommendation for SOC over ERCP with large-balloon dilation of papilla. Additional research is required on economic estimations of SOC and knowledge translation evaluations to implement SOC intervention in local contexts.

Clinical case of a patient who underwent small bowel examination with endoscopic capsule which was never recovered and two years later presented with dysphagia and was found with the capsule inside a Zenker´s diverticulum.

Management of distal intestinal obstruction syndrome by enteroscopy in a post-lung transplant patient.

This is a case of a male patient who had a post-lung transplant complication given to distal intestinal obstruction by meconium. He was managed with laxative irrigation though enteroscope directly in the ileum with immediate resolution, without complications, avoiding surgical management. No similar cases have been reported.

Recomendaciones para la sedación y la analgesia por médicos no anestesiólogos y odontólogos de pacientes mayores de 12 años / Sedation and analgesia recommendations for non-anesthesiologist physicians and dentists in patients over 12 years old

Las complicaciones relacionadas con la sedación son, en su enorme mayoría, prevenibles. El presente documento establece unas recomendaciones para que los no anestesiólogos puedan realizar sedaciones nivel I y II con un buen nivel de seguridad. Sus aspectos másimportantes son: administración de la sedación por una persona diferente del operador; recomendaciones en cuanto a la capacitación, la monitorización, el uso de un solo medicamento para la sedación y la disponibilidad de medicamentos y equipos de respaldo;la necesidad de realizar una evaluación previa a la sedación, así como el consentimiento informado y el registro durante el procedimiento; y recomendaciones para considerar un bajo umbral con el fin de solicitar el apoyo de un anestesiólogo.

Most of the complications related to sedation are preventable. This document defines some recommendations for non-anesthesiologists so that they can provide sedation level I and II with adequate safety. The most important recommendations are: that the sedation be provided by someone different from the person who performs the surgical procedure; designation of the training and monitoring of thje person who sedates; the use of only one medication for sedation, and the availability of medications and equipment to manage complications; the mandatory need of an assessment prior to the sedation, as well as informed consent and record of events during the procedure; and the recommendation of having a low threshold to request the support of an anesthesiologist.
