INTRODUCTION AND AIM: Various techniques have been proposed for the repair of abdominal wall defects (AWD) with varying rates of success. Despite the development of new materials and modifications of surgical technique, no single approach has emerged as the optimum way to close large AWD. We report a method for repairing large incisional and recurrent abdominal wall hernias using a double-mesh technique. The defect is closed using an underlay biological implant and an onlay synthetic mesh, which is 'quilted' to the underlying abdominal wall and biological implant. The current study reports our initial experience with this approach in ten consecutive patients operated on for large AWD.

METHODS: In this prospective observational study the following data were collected: age, gender, previous surgery, co-morbidities, situation and size of the defect, antibiotic therapy, hospital stay, postoperative complications and bacteriology in case of infection. The patients were reviewed at 1, 3 and 6 months, and 1-year postsurgery.

RESULTS: Overall all ten AWD of ≥ 75 cm(2) were reconstructed successfully using the quilting technique. Median age of patients was 61 years (range 47-73 years); male:female ratio was 3:2 and median weight was 107.5 kg. Two patients developed a wound infection and were treated successfully with antibiotics. At median follow-up of 15.5 months (range 6-29 months) there was no case of recurrence.

CONCLUSION: The use of double-layer of porcine acellular dermal collagen implant and polypropylene mesh in reconstruction of AWD can be considered a safe and effective treatment. The early short-term results are encouraging with few complications.
