Abstract:
Objective:To summarize the characteristics of oral contrast ultrasound in patients with esophageal hiatal hernia (EHH), to screen the diagnostic criteria for EHH diagnosis by oral contrast ultrasound and to evaluate their diagnostic values.Methods:Sixty-one patients who visited the Hernia and Abdominal Wall Surgery Department of the Sixth Affiliated Hospital of Sun Yat-sen University from June 2023 to December 2023 for symptoms of acid reflux, heartburn, belching, recurrent epigastric pain, chest pain, and cough, and who were clinically suspected of EHH and underwent oral contrast ultrasound were retrospectively collected. The internal diameter of the esophageal hiatus, the length of the intraabdominal esophagus (IAEL), the angle of His, the supradiaphragmatic hernia sac, the sign of gastric wall sliding, and the sign of esophageal-gastric ring uplift were recorded by oral contrast ultrasound. All ultrasonographic data were retrospectively analyzed, and the diagnosis of EHH by surgery or with the simultaneous diagnosis of EHH by barium meal examination and gastroscopy were used as the gold standard. The diagnostic criteria of oral contrast ultrasound for EHH were obtained and their diagnostic values were evaluated by ROC curve analysis.Results:The indicators of EHH diagnosed by oral contrast ultrasound were analyzed according to ROC curves as follows: internal diameter of esophageal hiatus >15 mm (AUC=0.913), IAEL≤33 mm (AUC=0.776), angle of His > 90° (AUC=0.735), supradiaphragmatic hernia sac (AUC=0.913), gastric wall sliding sign (AUC=0.827), upward displacement of the esophagogastric ring (AUC=0.721). The diagnostic sensitivity, specificity, accuracy, positive predictive value, negative predictive value, AUC, and 95% CI of the diagnosis of EHH using the internal diameter of the esophageal hiatus >15 mm or the presence of a supradiaphragmatic hernia sac as the diagnostic criterion for the diagnosis of EHH by oral contrast ultrasound were 86.5%, 100%, 88.5%, 100%, 56.3%, 0.933, and 0.838-0.981, respectively. Conclusions:The optimal diagnostic criterion for EHH diagnosis by oral contrast ultrasound is esophageal hiatal internal diameter >15 mm or the presence of supradiaphragmatic hernia sac, which has 100% specificity and positive predictive value. It is recommended to be widely used as a screening test for EHH in the clinic.
