Paraesophageal Hernia and Reflux Prevention: Is One Fundoplication Better than the Other?

The management of paraesophageal hernia (PEH) is one of the most debated in surgery. Trends regarding indications, approach (open, laparoscopic, thoracoscopic), sac excision, mesh placement, and routine performance of fundoplication have changed over time. Today, most surgeons tend to perform a laparoscopic PEH repair that entails the excision of the sac, liberal use of a mesh to buttress the hiatus, and the addition of an anti-reflux procedure. Nevertheless, very little has been written on which type of fundoplication should be performed in these patients. Therefore, the goal of our study was to provide an evidence-based overview of which type of fundoplication should be performed during a PEH repair and the role of preoperative function tests in the decision-making METHODS: We searched the MEDLINE, Cochran, PubMed, Google Scholar, and Embase databases for papers published between 1996 and 2016 pertaining to the surgical treatment of PEH. We hand-searched the bibliographies of included studies and we excluded all reviews and case reports. We selected clinical studies and technical reports. We only considered papers stating rationales for the type of fundoplication performed.

Our search yielded 24 articles: 17 clinical studies and 7 technical reports. In five of the clinical studies, a fundoplication was added only to patients with reflux symptoms. In all clinical studies, the most performed procedure was a total fundoplication (Nissen or Nissen-Rossetti), whereas a partial fundoplication (Toupet more frequently than Dor) or no fundoplication was reserved to those with impaired esophageal motility. All seven technical reports recommended a tailored approach and suggested adding a partial fundoplication (mainly Toupet) when the manometric findings showed esophageal dismotility.

The argument of whether or not a fundoplication should be added to a PEH repair in patients without evidence of reflux still persists. However, this review highlights that, when a fundoplication is performed, a tailored approach based on preoperative function tests is almost always preferred.
