Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The SIMBIOSE trial is a large multicenter phase III prospective randomized controlled single blinded trial comparing the use of biological mesh versus traditional wound care without biological mesh in patients with an infected incisional ventral hernia. The primary endpoint is 6-month infectious and/or wound morbidity. Secondary endpoints are wound infection rate at 45 days, 3 months and 1 year, recurrent hernia rates at 1, 2 and 3 years, postoperative pain, quality of life, time to healing, need for wound reoperation, impact of the cross-linked mesh structure, and medico-economic evaluation. One hundred patients need to be included.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

biological mesh

patients will undergo the implantation of a biological mesh (after debridement and treatment of the infection) at the same time as the primary operation, or within one month of randomization.

Group Type EXPERIMENTAL

Biological mesh

Intervention Type BIOLOGICAL

patients will undergo the implantation of a biological mesh (after debridement and treatment of the infection) at the same time as the primary operation, or within one month of randomization.

without biological mesh

patients undergo traditional wound care (debridement and treatment of infection), without placement of a biological mesh. For arm B, the common wound care used follows the normal practice of the treating surgeon, except the placement of the biological mesh, which must not be performed within 6 months of randomization.

Group Type ACTIVE_COMPARATOR

without biological mesh

Intervention Type PROCEDURE

patients undergo traditional wound care (debridement and treatment of infection), without placement of a biological mesh. For arm B, the common wound care used follows the normal practice of the treating surgeon, except the placement of the biological mesh, which must not be performed within 6 months of randomization In cases of treatment failure at 6 months, patients of arm B are allowed to undergo any treatment which the treating surgeon views suitable, including a surgical procedure with implantation of a biological mesh
