Outcomes

Primary Outcome Measures

foreign body sensation
Quality of life measurement based on the occurrence of a foreign body sensation for more than 3 months within 12 month after surgery.

Secondary Outcome Measures

postoperative seroma
Fluid collection in the wound area
wound infection
Clinical identification of superficial and deep wound infections.
haematoma
hematoma in the wound area
hematoma requiring surgery
hematoma in the wound area requiring surgery
chronic pain
Chronic pain is defined as pain sensations that persist for more than 3 months after surgery. A Visual Analog Scale (VAS) with a range of 0-10 is used as a tool to measure pain.
hernia recurrence
hernia recurrence is defined as a new abdominal wall defect in the area of surgery

5. Study Description

Brief Summary
In this randomized, controlled, prospective multicentre clinical trial with a parallel group design a large-pore, lightweight polypropylene mesh (Ultrapro®) is compared to a small-pore, heavyweight polypropylene mesh (Premilene®), within a standardized, retromuscular mesh augmentation to identify the superiority of the lightweight mesh. Included patients are examined at five scheduled follow-up visits (5 and 21 days, 4, 12 and 24 months after surgery). The primary outcome criterion is foreign body sensation 12 month after surgery. Further secondary endpoint criteria are the occurrence of haematoma or haematoma requiring surgery at the 5-day visit, seroma, wound infection, and chronic pain within 24 months postoperatively. Quality of life was investigated by the SF-36®.
