Background. Isolation of the enteroatmospheric fistula (EAF) opening and prevention of contamination of the rest of the wound by effluent are important factors in the management of EAF. Objective. The aim of this study is to describe an easily reproducible technique for effluent control in patients with EAF. Materials and Methods. A retrospective analysis was conducted on all patients who underwent the present technique between 2013 and 2015. The surgical technique included condom-EAF anastomosis, fistula ring creation, negative pressure wound therapy (NPWT), and adaptation of an ostomy bag. Results. A total of 7 patients with a Björck grade 4 abdomen were included. All fistulas were located in the small bowel with a median number of 2 EAFs (range, 2–3) in each patient, and the majority had moderate output volume. The mean number of NPWT changes was 10 (range, 5–18), the mean time of NPWT use was 75.7 days (range, 60–120 days), and the mean length of stay was 108.2 days (range, 103–160 days). The mean time of ostomy formation to restitution of bowel continuity was 14.3 months (range, 8–20 months). Open anterior component separation was employed in all cases for closure of the abdominal wall. No mortality, ventral herniation, or refistulization was registered in the study. The mean follow-up time was 8.5 months (range, 6–12 months). Conclusions. This is an easily reproducible and safe technique for effluent control in patients with Björk grade 4 abdomen with established EAF.
