Abstract: Objective To summarize and analyze the long-term efficacy of laparoscopic treatment of children with hiatal hernia.
Methods The data of 49 consecutive cases of pediatric hiatal hernia treated by laparoscopy in our hospital from January 2014 to December 2018 were retrospectively analyzed,with an age range of 2 to 85 months and a median of 18.5 months(P25 to P75,12.3 to 28.8 months).There were 1 cases of sliding hernia,17 cases of paraesophageal hernia and 31 cases of mixed hernia.Laparoscopic hiatal hernia repair and antireflux surgery were performed using a 4-well method.The operative time,intraoperative blood loss,recovery time of gastrointestinal function,postoperative hospital stay and postoperative complications were recorded,and the postoperative recovery was observed.
Results 3 cases were converted to open surgery,and the remaining 46 cases underwent laparoscopic surgery successfully.Postoperative follow-up ranged from 27 to 83 months,with a median of 64.0 months(P25 to P75,47.3 to 73.8 months).One patient with esophageal stenosis was significantly relieved after balloon dilation of esophageal stenosis.9 cases of gastroesophageal reflux,5 cases of drug antiacid treatment;One case of hiatal hernia recurred and was re-operated.
Conclusion The majority of children's hiatal hernia can be treated by laparoscopy,the operation is safe and feasible,the incidence of postoperative complications and recurrence rate is low,and the long-term treatment effect is satisfactory.
