title: A systematic review on the use of prophylactic mesh during primary stoma formation to prevent parastomal hernia formation.
abstract: OBJECTIVE
  Despite advances in surgical technique, parastomal herniation is common. This systematic review aims to assess the efficacy of prophylactic mesh at primary operation in reducing the incidence of parastomal hernia.
  
  
  METHODS
  Medline, EMBASE and CENTRAL were searched for relevant publications between January 1980 and January 2010. The search strategy included text terms and MESH headings for parastomal hernia, mesh and prevention and/or prophylaxis of hernia. No language restrictions were applied. Bibliographies from the papers requested in full were manually checked. All randomized controlled trials were included regardless of the language of publication. Results were extracted from the papers by two observers independently on a predefined data sheet. Disagreements were resolved by discussion. REVMAN 5 was used for statistical analysis.
  
  
  RESULTS
  Of 27 possible studies three randomized controlled trials fulfilled the criteria for systematic review, with a total of 128 patients (mesh 64, no mesh 64). The two study groups were well matched demographically. The incidence of parastomal hernia in the mesh group was 12.5% (8/64) compared with 53% (34/64) in the control group (P < 0.0001). There was no difference in mesh related morbidity in the two groups.
  
  
  CONCLUSIONS
  Although only three trials with 128 patients fulfilled the criteria for this systematic review, the data suggest that the use of prophylactic prosthetic mesh at the time of primary stoma formation reduces the incidence of parastomal hernia.
