The VAWCM method provided a high fascial closure rate after long-term treatment of OA. Technique-related complications were few. No patient was left with a large planned ventral hernia.

VAWCM treatment results in high incidence of IH. However, at five years, there was no detectable difference in abdominal wall complaints and QoL in patients with IH compared to those without. Lower QoL appeared mainly to be associated with the presence of major co-morbidity.

Incisional hernia incidence 1 year after OA therapy with VAWCM was high. Most hernias were small and asymptomatic, unlike the giant planned ventral hernias of the past.
