title: Paraoesophageal herniation: a review.
abstract: BACKGROUND
  Paraoesophageal hiatus herniae repair can represent a formidable challenge. Afflicted patients tend to be elderly with multiple infirmities often with cardio-pulmonary dysfunction. They may present acutely with protracted vomiting and concurrent biochemical imbalances and it is a technically demanding procedure. There are several debated issues regarding operative technique. This paper will attempt to explain the nature of paraoesophageal hiatus herniae and reviews the recommended pre-operative investigations and operative strategies available.
  
  
  METHODS
  A literature search was performed from Pubmed and suitable clinical papers were selected for review. When attempting to address whether meshes should be included routinely, electronic searches were performed in PubMed, Embase and the Cochrane library. A systematic search was done with the following medical subject heading (MeSH) terms: 'paraoesophageal hernia repair' AND 'mesh'. In PubMed and Embase the search was carried out with the limits 'humans', 'English language', 'all adult: 19+ years' and 'published between 1990 and 2010'. A manual cross-reference search of the bibliographies of included papers was carried out to identify additional potentially relevant studies.
  
  
  RESULTS
  Firm conclusions are difficult to draw due to the diverse nature of both the disorder and the presentation however principals of management can be suggested. Similarly, there is no conclusive proof of the most effective operative technique and therefore the options are described.
  
  
  CONCLUSIONS
  Due to the relative lack of cases encountered at smaller institutions, there is a good argument for centralisation of these cases into regional centres to allow research and facilitate improvements in care.
