To investigate the clinical effect of laparoscopic repair of esophageal hiatal hernia combined with modified DOR fundoplication in the treatment of esophageal hiatal hernia complicated with gastroesophageal reflux disease.

108 patients with esophageal hiatal hernia complicated with gastroesophageal reflux disease treated in the Second Affiliated Hospital of Hebei North University from January 2016 to January 2019 were selected for retrospective study. The patients were divided into two groups according to different surgical methods, with 54 patients in each group. The control group received routine open surgery, and the combined group received laparoscopic hiatal hernia (HH) repair combined with modified DOR fundoplication. The reflux time, reflux times, DeMeester score, lower esophageal sphincter pressure and Gerd Q scale score before and 6 months after operation were compared between the two groups.

There was no significant difference in preoperative reflux time, reflux times, DeMeester score, lower esophageal sphincter pressure and Gerd Q scale between the two groups (P>0.05). The reflux symptoms of the two groups were significantly improved 6 months after operation compared with those before operation (P<0.05). There were significant differences in postoperative reflux time, reflux times, DeMeester score, lower esophageal sphincter pressure and Gerd Q scale between the two groups (P<0.05). The operation time, intraoperative bleeding and postoperative hospital stay in the combined group were significantly better than those in the control group (P<0.05).

Laparoscopic HH repair combined with modified DOR fundoplication is effective in patients with HH complicated with gastroesophageal reflux disease, which is conducive to rapid recovery, minimally invasive, safe and has satisfactory short-term efficacy.
