Long-term follow-up of full-thickness skin grafting in giant incisional hernia repair: a randomised controlled trial.

Abstract

<h4>Purpose</h4>Conventional repair of a giant incisional hernia often requires implantation of a synthetic mesh (SM). However, this surgical procedure can lead to discomfort, pain, and potentially serious complications. Full-thickness skin grafting (FTSG) could offer an alternative to SM, less prone to complications related to implantation of a foreign body in the abdominal wall. The aim of this study was to compare the use of FTSG to conventional SM in the repair of giant incisional hernia.<h4>Methods</h4>Patients with a giant incisional hernia (> 10 cm width) were randomised to repair with either FTSG or SM. 3-month and 1-year follow-ups have already been reported. A clinical follow-up was performed 3 years after repair, assessing potential complications and recurrence. SF-36, EQ-5D and VHPQ questionnaires were answered at 3 years and an average of 9 years (long-term follow-up) after surgery to assess the impact of the intervention on quality-of-life (QoL).<h4>Results</h4>Fifty-two patients were included. Five recurrences in the FTSG group and three in the SM group were noted at the clinical follow-up 3 years after surgery, but the difference was not significant (p = 0.313). No new procedure-related complication had occurred since the one-year follow-up. There were no relevant differences in QoL between the groups. However, there were significant improvemnts in both physical, emotional, and mental domains of the SF-36 questionnaire in both groups.<h4>Conclusion</h4>The results of this long-term follow-up together with the results from previous follow-ups indicate that autologous FTSG as reinforcement in giant incisional hernia repair is an alternative to conventional repair with SM.<h4>Trial registration</h4>The study was registered August 10, 2011 at ClinicalTrials.gov (ID NCT01413412), retrospectively registered.
