Investigating the role of high-resolution esophageal manometry in the treatment of esophageal hiatus hernia, and to provide a clinical basis for the diagnosis and operation of hiatal hernia.

From April 2016 to October 2018, 67 patients were diagnosed with esophageal hiatal hernia and performed with laparoscopic esophageal hiatus hernia repair in Beijing Chaoyang Hospital. The above data was analyzed to calculate the diagnosis rate of esophageal hiatal hernia by gastroscopy and high-resolution esophageal manometry, analyze the operation and summarize high-resolution esophageal manometry with high resolution manometry (HRM) technique in laparoscopic treatment of esophageal hiatal hernia.

The detection rate of HRM was 80.59% (54/67), the specificity was 100% (54/54), and the confirmed by gastroscopy was 52.24% (35/67). Among them, 35 patients were diagnosed by gastroscopy and HRM, with 64.81% (35/54). The detection rate of high-resolution esophageal manometry was significantly higher than that of gastroscopy; 48 cases were treated with laparoscopic esophageal hiatal hernia repair, and 7 patients gave up surgery to choose conservative treatment. 12 patients complicated with other underlying diseases, took conservative treatment or elective surgery.

High-resolution esophageal manometry can accurately and intuitively describe the difference of gastroesophageal pressure in patients with hiatal hernia, and the diagnosis rate is high, which can effectively guide the surgical plan.
