Multiplanar MDCT Measurement of Esophageal Hiatus Surface Area: Association with Hiatal Hernia and GERD

摘要

BackgroundAccurate measurement of esophageal hiatus size is clinically important, especially when antireflux surgery is planned. We present a novel method for in vivo measurement of esophageal hiatal surface area using MDCT multiplanar reconstruction. We aimed to determine if large hiatal area is associated with hiatal hernia and gastroesophageal reflux disease.
