Postoperative seroma formation is one of the most common complications after ventral hernia repair. Although some seromas may not have clinical impact, postoperative seroma formation often causes pain and discomfort and may even compromise wound healing. The use of postoperative abdominal binder is often recommended after ventral hernia repair to prevent seroma and diminish pain, but still with no scientific evidence. The primary aim of the present study is to investigate the effect of postoperative abdominal binders after laparoscopic ventral hernia repair on postoperative pain, discomfort and quality of life. Secondary, we register seroma formation.
Method and material Randomized, controlled, multi-center, investigator-blinded study. A minimum of 56 patients (2X28 umbi/epi) are included, inclusion number is based on power calculations. Patients are randomized either to abdominal binder or no abdominal binder. The abdominal binder is worn from immediately after the operation and continuously for 7 days, night and day. Outcomes are based on patient self-reported registrations using Visual Analog Scales (VAS) and Carolina Comfort Scale (CCS), which is a validated, hernia-specific tool to estimate quality of life, pain and discomfort. Patients are followed-up for 30 days. For secondary outcome we use ultrasound to measure the volume of seroma formation. We use Mann-Witney, non-parametric statistics calculating the seroma formation and Friedmanns test for pain, discomfort and quality of life for the effect of time on inter- and intragroup differences during the study period. P < 0.05 is considered significant.

Active Comparator: abdominal binder
The abdominal binder is worn from immediately after the operation and continuously for 7 days, night and day. The belts are standard elastic belts (ostomy belts) from "ETO garments©" with standard height of 22 cm. and five different sizes in width (S, M, L, XL, XXL- depending on waist measure). A fitting will be done before the operation by waist measurement according to the recommendation from the company.
Device: ETO garments
patients wearing abdominal binder for 7 days postoperatively
No Intervention: no abdominal binder

- Visual Analog Scale of Pain Activity [ Time Frame: 24 hours after hernia repair ]Outcome is based on patient self-reported registrations using Visual Analog Scales (VAS) where 0 is no pain in activity and 100 is worst imaginable pain in activity.
- Seroma Formation [ Time Frame: postoperative day 7 ]Seroma formation measured on day 7 postoperatively with trans abdominal ultrasound scan (US). The method used in this study to estimate the volume of seroma is to measure the longitudinal section and cross section of the effusion and thereby calculating the volume.
