This is a recording of a webinar that took place on May 27th, 2026.

This series aims to equip advanced practice providers with practical, guideline-aligned approaches to the diagnosis and management of eosinophilic esophagitis (EoE). It is designed to build confidence in the use of both first-line and step-up therapies—including proton pump inhibitors, topical steroids, dietary therapy, dilation, and biologics—while emphasizing patient safety and shared decision-making. The program also focuses on standardizing longitudinal disease monitoring through symptoms, endoscopic findings (EREFS), and histology, with an emphasis on relapse prevention. Finally, it seeks to improve care coordination across gastroenterology, allergy, and nutrition services, including best practices for transitioning pediatric patients into adult care.

Part 1 addresses:

• EoE epidemiology and natural history for APPs
• When to suspect EoE: dysphagia, food impaction, chest pain, refractory heartburn
• Endoscopy essentials for APPs: EREFS scoring, biopsy protocol (number/site), documentation pearls
• Pathology: eosinophil counts, distribution, and pitfalls
• Distinguish EoE from GERD, EGIDs, celiac, infection, pill esophagitis
• Mini-quiz: Interpreting sample endoscopy photos and pathology reports
• Take-home: Diagnosis checklist, biopsy order set 

Participants will be able to:

• Recognize clinical features that should prompt evaluation for EoE in both pediatric and adult patients
• Describe endoscopic findings and biopsy strategies that improve diagnostic yield, including appropriate use of EREFS and multi-site biopsy protocols
• Interpret key histologic features of EoE and differentiate them from other causes of esophageal eosinophilia such as reflux esophagitis

1. Close other applications and browser tabs. This decreases the load on memory so your computer or other device can focus on streaming.
2. Use a 5 GHz frequency if your router supports it. The common 2.4 GHz frequency is used by household appliances, so is more crowded. Avoiding it is like getting into the carpool lane on a freeway: smoother sailing.
3. Use Ethernet instead of Wi-Fi if possible but GI LEAP is built with Wi-Fi in mind. 
4. Monitor your internet connection. If your ISP has promised you 5MBps and you are getting only 1MBps, it's time for a phone call to your internet provider to sort that out.
