Total vs partial fundoplication in the treatment of gastroesophageal reflux disease: a meta-analysis

Abstract

Objective: To perform a meta-analysis of randomized trials comparing partial fundoplication (PF) with total (Nissen) fundoplication (TF) for gastroesophageal reflux disease in terms of morbidity, efficacy, and long-term symptomatology.

Data sources: A structured Medline search for published studies.

Study selection: The available literature from 1975 until June 2007 was searched using the Medical Subject Headings of the National Library of Medicine term fundoplication and the free-text terms fundoplication, surgery, and reflux. Data were analyzed using Review Manager software (Cochrane Collaboration, Oxford, England).

Data extraction: Eleven trials were identified comparing TF with PF in 991 patients.

Data synthesis: Total fundoplication resulted in a significantly higher incidence of postoperative dysphagia (odds ratio [OR], 1.82-3.93; P < .001), bloating (OR, 1.07-2.56; P = .02), and flatulence (OR, 1.66-3.96; P < .001). No significant differences were noted in the incidence of esophagitis (OR, 0.72-2.7; P = .33), heartburn (OR, 0.48-1.52; P = .58), or persisting acid reflux (OR, 0.77-1.79; P = .45). The reoperation rate was significantly higher after TF compared with PF (OR, 1.13-3.95; P = .02). No significant differences were present in the proportion of patients experiencing a good or excellent long-term outcome (OR, 0.54-1.38; P = .53) or in the proportion of patients with a Visick I or II score (OR, 0.62-1.59; P = .99).

Conclusions: Partial fundoplication is a safe and effective alternative to TF, resulting in significantly fewer reoperations and a better functional outcome. The poor quality of the included trials warrants caution in the interpretation of the results of this meta-analysis.
