Abstract:

Objective

To analyze the effect of postoperative recurrence in anti-reflux surgery with protection of vagus.

Methods

Pubmed, web of science, Embase, ScienceDirect, ovid, CNKI database were searched and submitted for search until September 2019. A controlled clinical study comparing with or without vagotomy in anti-reflux surgery of the hiatal hernia was performed. Authors performed literature screening, data extraction and quality assessment. Cochrane 5.1.0 systematic review manual was applied for meta-analysis.

Results

A total of 11 retrospective clinical study were included. All the study were divided into two subgroups according to the methods of diagnosis for the recurrence of hiatal hernia:anatomic recurrence group and clinical recurrence group. More specifically,430 patients with vagotomy and 383 patients without vagotomy were included in anatomic recurrence group,.While 324 cases with vagotomy and 362 cases without vagotomy were analyzed in the other subgroup. The overall analysis of the included studies showed that compared with the non-vagotomy group, vagotomy group had a higher risk of postoperative recurrence of hiatal hernial in both subgroups.(P<0.0001, OR=1.96, 95%CI: 1.45~2.64 in anatomic recurrence group, P=0.01, RR=1.56, 95%CI: 1.10-2.22 in clinical recurrence group respectively).Combined subgroup analysis shows that the risk of recurrence in vagotomy group is higer than that of non-vagotomy group, with a reletive risk of 1.78, and a 95% confidence interval of 1.42~2.24 (P<0.00001), and the difference was statistically significant.

Conclusion

Protecting vagus in the procedure of anti-reflux surgery has a beneficial effect on reducing the postoperative recurrence, which deserves to practice in clinic.
