Abstract

Background: We present Bogota-VAC, a newly modified temporary abdominal closure (TAC) technique for open abdomen condition after abdominal compartment syndrome (ACS).

Methods: A thin isolation bag (Bogota bag) and a vacuum assisted closure (VAC) system were combined. A matching bag was tension-free fixed on the abdominal fascia by fascia suture. A ring shaped black polyurethane foam of the VAC system was placed into the gap between Bogota bag, abdominal fascia and the wound edge. A constant negative topic pressure of 50–75 mmHg was used in the VAC system.
Results: Intra-abdominal pressure (IAP: 22 ± 2 mmHg)of four patients with ACS after severe traumatic brain injury and one patient with isolated ACS after blunt abdominal trauma decreased significantly (p = 0.01)after decompressive laparotomy and treatment with Bogota-VAC (IAP: 10 ± 2 mmHg) and remained low, measured via urinary bladder pressure. Intracranial pressure (ICP) in the four traumatic brain injury patients decreased from 42 ± 13 mmHg to 15 ± 3 mmHg after abdominal decompression. Cerebral perfusion pressure (57 ± 14 mmHg) increased to 74 ± 2 mmHg.

Conclusion: The advantage of the presented Bogota-VAC is leak tightness, wound conditioning (soft tissue/fascia), skin protection and facilitation of nursing in combinationwith highest volume reserve capacity (VRC), thus preventing recurrent increased intra-abdominal and intracranial pressure in the initial phase after decompression of ACS compared to other TAC techniques.
