Randomised controlled trials (RCTs) that compared total fundoplication with partial fundoplication for the treatment of gastro-oesophageal reflux disease were eligible for inclusion in the review. Trials that compared fundoplication with Hill gastropexy were excluded.
Outcomes of interest included: postoperative morbidity, incidence of symptomatic adverse events (dysphagia, bloating, flatulence, oesophagitis, heartburn, acid reflux), reoperation rate, recurrence rate, and Visick score.
In approximately two thirds of included trials, partial fundoplication and total fundoplication were performed laparoscopically; the remaining trials used open surgery. The circumferential degrees of the partial wrap in the included trials were 90, 180, 180 to 200, 200, 270, and 300 degrees.
The authors did not state how many reviewers performed study selection.
