title: Retracted: Impact on quality of life of using an onlay mesh to prevent incisional hernia in midline laparotomy: a randomized clinical trial.
abstract: BACKGROUND
  Recent studies have demonstrated the effectiveness of using prophylactic meshes to achieve abdominal wall closure, decreasing the risk of incisional hernia. However, the effect of prophylactic mesh placement on a patient's quality of life has not yet been evaluated.
  
  
  METHODS
  A controlled, prospective, randomized, and blind study was carried out. The patients in group A (mesh) were fitted with a polypropylene mesh to reinforce the standard abdominal wall closure. The patients in group B (nonmesh) were given a standard abdominal wall closure and were not fitted with the mesh. All patients were administered the 36-Item Short-Form generic health questionnaire during their preoperation visit and during their 1-month, 6-month, and 1-year follow-up appointments. The scores of the questionnaires have been compared with those recorded when the questionnaire was administered before surgery.
  
  
  RESULTS
  The Kaplan-Meier survival curves show that the likelihood of incisional hernia at 12 months is 1.5% in mesh group compared with 35.9% in nonmesh group (p > 0.0001), which means that the differences are statistically significant. Patients with mesh placement had greater improvement in general health and bodily pain than patients in nonmesh group at 1-month and 6-month post operation. One year after operation, patients in the mesh group had statistically significant better quality of life than patients in the nonmesh group in the physical functioning, general health perceptions, vitality, social role functioning, mental health, physical component summary and mental component summary dimensions.
  
  
  CONCLUSIONS
  Fitting a prophylactic supra-aponeurotic mesh prevents incisional hernia.
