Randomized Pilot Study Comparing Two Vacuum-wound-dressings for Open Abdomen Treatment (ABDOVAC)

This study has been terminated.
(extended obligations of amended medical device law in Germany 2010 did not allow to continue and complete the trial due to budget limitation)

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.

Condition Intervention
Open Abdomen
Temporary Abdominal Closure
Procedure: Vacuum-Pack-technique for temporary abdominal closure
Procedure: Abdominal-dressing-technique for temporary abdominal closure

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Vacuum-Therapy in Open Abdomen Treatment - Randomized Pilot-trial Comparing Fascial Closure and Survival With "Vacuum-Pack"-Technique vs. "Abdominal Dressing"

Further study details as provided by Universitätsmedizin Mannheim:

Primary Outcome Measures:
  • Failure of delayed abdominal fascial closure (non-prevented ventral hernia) and/or in-hospital-death of any cause (combined primary outcome) [ Time Frame: until end of vacuum-therapy or death ]

Secondary Outcome Measures:
  • vacuum-therapy-related morbidity/complications [ Time Frame: until hospital dismissal or death ]
  • length of vacuum-therapy [ Time Frame: until end of vacuum-therapy or death ]
  • costs of vacuum-therapy [ Time Frame: until end of vacuum-therapy or death ]
  • total length of ICU-stay [ Time Frame: until end of ICU-therapy or death ]
  • post-dismissal health-related quality of life (SF36 and EQ-5D questionnaire) [ Time Frame: 12 weeks after hospital dismissal ]
  • recurrent hernia/abdominal wall dehiscence after initial facial closure during hospital stay [ Time Frame: 12 weeks post hospital dismissal ]

Enrollment: 3
