ASGE Postgraduate Course at ACG: Innovative Practices for the Endoscopist of Today, Tomorrow and Beyond (On-demand) | October 2023-5

Pdf Summary

The document is a summary of a presentation from the ASGE Postgraduate Course focused on the endoscopic management of hilar obstruction, delivered by Drs. Joanna Law, Swati Pawa, and Andrew Storm on October 22, 2023.<br /><br /><h3>Key Topics:</h3><br />1. <strong>Hilar Obstruction Management:</strong><br />   - Assess anatomy and choose an approach for hilar obstruction.<br />   - Review ASGE guidelines on whether to use endoscopic or percutaneous drainage, the number of liver segments to drain, and the ideal type of stent.<br /><br />2. <strong>Malignant Hilar Obstruction:</strong><br />   - Differentiates intrinsic vs. extrinsic obstruction.<br />   - Emphasizes a low 5-year survival rate (10%) and non-resectability (70%).<br /><br />3. <strong>Diagnostics and Imaging:</strong><br />   - Criteria for diagnosing hilar cholangiocarcinoma.<br />   - Goals of imaging to identify masses, stage the disease, and plan drainage.<br /><br />4. <strong>Bismuth Corlette Classification:</strong><br />   - Classification assists in deciding between endoscopic procedures and surgery.<br /><br />5. <strong>Case Studies and Guidelines:</strong><br />   - <strong>Case #1:</strong> Discusses a 72-year-old man with malignant hilar obstruction, highlighting ASGE’s recommendations against routine use of PTBD.<br />   - <strong>Case #2:</strong> Evaluates stent choices in a 58-year-old with metastatic gastric cancer, favoring metal stents for poor prognosis and plastic stents when the strategy is unclear.<br />   - <strong>Case #3:</strong> Addresses complications and outcomes when traditional stents fail in a 68-year-old with unresectable cholangiocarcinoma.<br />   - <strong>Case #4:</strong> Highlights the use of radiofrequency ablation (RFA) in endoscopic treatments.<br /><br /><h3>Emerging Techniques:</h3><br />- <strong>Radiofrequency Ablation (RFA):</strong><br />  - Explained with technical details and its role in improving stent patency and survival with fewer side effects compared to PDT.<br />  - Describes the procedure, equipment, and potential adverse events.<br /><br /><h3>Summary Guidelines:</h3><br />- Review and assess liver volumes through cross-sectional imaging.<br />- Discuss cases in multidisciplinary teams.<br />- Limit contrast injections and focus drainage on non-atrophic, viable liver segments.<br />- Understand different drainage methods (endoscopic and percutaneous) and the use of adjunct therapies for non-operable strictures.<br /><br />The presentation concludes with a recommendation to continually evaluate and adopt emerging techniques for managing complex cases of hilar obstruction.
