Intraoperative Endomanometric Laparoscopic Nissen Fundoplication Improves Postoperative Outcomes

Laparoscopic Nissen fundoplication (LNF) is a surgical intervention for gastroesophageal reflux disease (GERD); however, it can be followed by recurrent symptoms or complications that may affect patient satisfaction. Intraoperative endomanometric evaluation of esophagogastric competence and pressure, combined with LNF in patients with large sliding hiatus hernia (>5cm) with severe GERD (DeMeester score >100), is needed.

Study design: This is a retrospective, multicenter, comparative study. Baseline characteristics, initial reflux symptoms, preoperative and postoperative antacid medication use, postoperative complications (dysphagia and gas bloat syndrome), recurrent symptoms, and satisfaction were collected from a prospective database. Outcomes measures were recurrent reflux symptoms, postoperative side-effects, and satisfaction with surgery. Quantitative data were compared between the studied groups using the independent t-test or Mann-Whitney U test for normally and non-normally distributed numerical variables, respectively.

This study contributes to the mounting evidence for the effectiveness of endomanometric use during LNF. Intraoperative HRM and Endoscope were feasible in all patients and demonstrated that the clinical outcomes for endomanometric NF were favorable from an effectiveness and safety standpoint.

Inclusion criteria
