Collagen-coated Vicryl mesh is not a suitable material for repair of diaphragmatic defects.

Encouraged by the results in abdominal wall defects, the authors used the collagen-coated Vicryl mesh (CCVM) in repair of diaphragmatic defects in two patients. In a patient with recurrent diaphragmatic hernia, CCVM was used to reinforce the anterior abdominal muscle flap. The hernia recurred after 8 months. In another patient, it was used to repair a large diaphragmatic defect. This patient had a recurrence of the hernia in 10 weeks. The results suggestthat CCVM is not a good material for repairing the diaphragmatic defect. However, it can be used to reinforce other types of repairs.
