OA07.2. Baseline Mucosal Impedance on High-Resolution Impedance Manometry Distinguishes Active From Inactive Eosinophilic Esophagitis

Fangfang Wang, Josealberto Arenas Martinez, Catherine Freeman, Michael Crowell et autres

Abstract Topic Benign Disease: Eosinophilic Esophagitis Background Active inflammation in eosinophilic esophagitis (EoE) disrupts the mucosal barrier, leading to dilated intercellular spaces and decreased transepithelial electrical resistance. Mucosal impedance (MI) has been used to assess mucosal integrity in EoE. We evaluated whether …

OA07.1. Clinical Features and Treatment Outcomes in Esophageal Lichen Planus: A Retrospective Multicenter Cohort Study

Evan Wilder, Russaal Mann, Shiwani Keswani, Josealberto Arenas Martinez et autres

Abstract Topic Benign Disease: Other Background Lichen planus is a chronic immune-mediated skin disease that may involve the esophagus. Esophageal lichen planus (ELP) is considered rare, but likely underdiagnosed. Lack of published guidelines for ELP results in significant treatment variability. Given heterogeneous …

PD06.04. Diagnostic Yield of Esophagram Compared to Gold Standard Ambulatory Reflux Monitoring for Detection of Gastroesophageal Reflux Disease

Fangfang Wang, Anika Vela, Michael Crowell, Francisco Ramirez et autres

Abstract Topic Benign Disease: Gastro-Esophageal Reflux and Hiatal Hernia Background Ambulatory reflux monitoring off acid suppression is the gold standard for diagnosing gastroesophageal reflux disease (GERD). Barium esophagram (BE) routinely evaluates reflux, but its diagnostic accuracy remains uncertain. We assessed whether BE …

P1.026. Diagnostic Yield of Esophagram Compared to Gold Standard Ambulatory Reflux Monitoring for Detection of Gastroesophageal Reflux Disease

Fangfang Wang, Anika Vela, Josealberto Arenas-Martinez, Michael Crowell et autres

Abstract Topic Benign Disease: Gastro-Esophageal Reflux and Hiatal Hernia Background Ambulatory reflux monitoring (wireless pH or catheter-based pH-impedance) performed off acid suppression is the gold standard for diagnosing gastroesophageal reflux disease (GERD). Barium esophagram (BE), commonly used to evaluate esophageal symptoms, routinely …

S948 Multimodal Assessment of Esophageal Peristalsis in Gastroesophageal Reflux Disease

Fangfang Wang, Varan Perananthan, Andree Koop, Jennifer L. Horsley‐Silva et autres

Introduction: Peristalsis is a defense mechanism against gastroesophageal reflux disease (GERD) by clearing refluxate. Data are limited regarding the relative contributions of primary peristalsis, secondary peristalsis, and peristaltic augmentation in GERD. Aim: evaluate the association between these peristaltic metrics and GERD via …

S1079 Diagnostic Yield of Esophagram Compared to Gold Standard Esophageal Manometry for Detection of Esophageal Motility Abnormalities

Fangfang Wang, Michael D. Crowell, Marcelo Vela, Francisco C. Ramirez

Introduction: High resolution manometry (HRM) is the gold standard to diagnose esophageal motility disorders. Barium esophagram (BE), often used to evaluate dysphagia or other esophageal symptoms, routinely includes esophageal motility assessment. There are limited data evaluating the accuracy of BE to assess …

S387 Six Food Elimination Diet—Our Experience at a Tertiary Academic Center

Fangfang Wang, Michelle Sharpe, Patricia V. Hernandez, Carolyn Mead‐Harvey et autres

Introduction: The 6-food elimination diet (SFED) has been widely used for trigger food identification in Eosinophilic Esophagitis (EoE). Since the inception of SFED, other strategies have emerged including 1-food, 2-food, 4-food elimination diets, and the step-up approach. These other strategies have a …

How Did Consultants and Trainees Respond to a Survey About Proton Pump Inhibitors in a Tertiary Academic Center?

Mohanad Al-Qaisi, Allon Kahn, George E. Burdick, Marcelo Vela et autres

Introduction: Proton pump inhibitors (PPI) are ubiquitous in the field of gastroenterology. Recent publications suggest possible links between chronic PPI use and several adverse events. As a result, more patients are asking questions about risk of PPI use, and providers face challenges …
