Conditions open abdomen, temporary abdominal closure
Treatments vacuum-pack-technique for temporary abdominal closure, abdominal-dressing-technique for temporary abdominal closure
Sponsor Universitätsmedizin Mannheim
Collaborator German Research Foundation
Start date February 2010
End date May 2014
Trial size 20 participants
Trial identifier NCT00834314, 2008-291 M-MA


The primary purpose of the study is to determine whether two vacuum-wound-dressing techniques (the so called "abdominal dressing" versus "vacuum-pack-technique") are equally effective in the treatment of open abdomen.

Secondary purpose is the comparison of feasibility and economic aspects.

Eligibility Criteria

Male or female participants at least 18 years old.
