A Prospective Study in Patients Undergoing Primary Ventral Hernia Repair Using Parietex™ Composite Ventral Patch

Prospective, multicenter, multinational non‐comparative study.

Primary Endpoint: Primary hernia recurrence* rate at 24 month follow‐up. The evaluation of
hernia recurrence will be performed during a physical examination and by ultrasonography.

Secondary Endpoints: Primary hernia recurrence* rate at 1, 6 and 12 month follow‐up. The
evaluation of hernia recurrence will be performed during a physical examination and confirmed
by ultrasonography.

(*Recurrence is defined as a clinically manifested bulge or a protrusion exacerbated by a
Valsalva maneuver.)

Safety Parameters:

Deep and superficial infection (A Surgical Site Infection (SSI) will be defined in the study
according to the Centers for Disease Control and Prevention (CDC) criteria for diagnosis of
SSI).

Pain / Chronic pain Other post‐operative complications (complications related to visceral
adhesions, Ileus, seroma, hematoma...) Analgesics consumption Risk factors (severity and
treatment) Efficacy Parameters: Recurrence of primary ventral hernia Operative time Time of
the mesh positioning Length of Hospital Stay Ease of use (Mesh handling and manipulability,
comfort of use …) Return to daily activities/ work Patient satisfaction Patient comfort
