A Herniorrhaphy Lamination Technique for the Reconstruction of Midline Abdominal Wall Defects

The primary goal of abdominal wall reconstruction is to prevent hernia recurrence through robust and durable repair. Synthetic mesh utilization can provide sound strength but is susceptible to extrusion, infection, and intestinal fistulization. The use of autologous fasciae latae to reinforce the primary fascial reapproximation has mostly been abandoned, presumably because synthetic patches are readily available. There is a specific demand for a sustainable, less-invasive, and ready-to-use repair method without mesh. The authors devised a herniorrhaphy lamination technique using local musculofascial flaps inspired by composite laminates. In this procedure, the primary fascial reapproximation is reinforced with 3 additional laminated musculofascial layers: (1) turnover hinge flaps of the anterior sheath of the rectus abdominis, (2) bilateral rectus abdominis, and (3) advancement flaps of newly generated edges of the fascia of the rectus sheath. Our technique’s stability is essentially due to the mechanical superiority of the centralized pipe-like structure of musculofascia. Between February 2009 and November 2019, we used the lamination technique to repair midline incisional hernias in 10 patients. The operative procedure was successful in all patients, and there has been no evidence of recurrence. The follow-up period ranged from 12 to 69 months, with a mean follow-up of 35 months. The herniorrhaphy lamination technique to reinforce the primary repair can help prevent hernia recurrence. Although our technique is suitable for a small-sized defect, it is less invasive, and can be readily applied. Because it does not include any mesh, it is suitable for the contaminated abdominal wall reconstruction.
