Background/Aim: Post-laparotomy wound sepsis and dehiscence occur in 0.25% to 3% of patients. Frequently, definitive fascial and/or cutaneous reconstructions cannot be performed in an immediate setting due to the wound condition or the general condition of the patient. Commercial VAC (Kinetic Concepts, Inc, San Antonio, TX) have been predominantly used for treatment of the open abdomen and in abdominal sepsis. However, commercial devices are either not available or prohibitively expensive for most patients in resource-poor regions. The method described herein is a relatively crude and low cost one applying the principals of topical negative pressure and temporary abdominal wound closure and our aim is to check its foasibility, safety and efficacy as a temporary abdominal closure method in post laparotomy wound sepsis and wound dehiscence.
Patients and methods: This prospective study included 17 patients with significant post
laparotomy wound dehiscence admitted to surgery department between June 2008 and May
2011. Vacuum packing closure therapy was administered for the whole 17 patients. Eleven patients (64 %) had complete fascial dehiscence with exposed bowel and six patients (36 %) had partial thickness fascial dehiscence. The evaluations included descriptive characteristics of the patients, rate of primary fascial closure and vacuum packing related morbidity and mortality.
Results: Of these 11 patients with full thickness wound dehiscence and bowel exposure, two patients died of vacuum packing unrelated problems, six patients underwent successful primary fascial closure. In those 6 patients with partial thickness wound dehiscence. vacuum packing therapy achieved satisfactory wound healing in all the patients, Problems related to vacuum packing therapy included necrosis of fascial edges (2 patients) and blister under the adhesive tape (2 patients). No variables had a significant influence on vacuum packing wound therapy specific morbidity or primary closure rate in the univariate analysis. Three variables showed a significant influence on mortality: age (P
