Mechanically powered ambulatory negative pressure wound therapy device for treatment of a colostomy takedown site

The management of postostomy takedown surgical wound sites can be challenging. Complications from these contaminated wounds can lead to serious complications such as hernia formation and increased healthcare costs. Negative pressure wound therapy (NPWT) has been shown to be potentially helpful in managing these heavily colonized wound sites. We report the case of a mechanically powered ambulatory NPWT device (SNaP Wound Care System; Spiracur Inc, Sunnyvale, California) for treating these postcolostomy takedown wounds.

A young 9-year-old boy in Port-Au-Prince, Haiti, had under gone colostomy as a protective measure after pelvic fracture 5 months prior. Having healed the pelvic fracture and being fully ambulatory, he underwent takedown of his colostomy with reanastomosis of the bowel. At the completion of surgery, the ostomy wound site was managed by a mechanically powered NPWT device. This allowed the patient to remain ambulatory without the need for attachment to a heavier electrically powered NPWT device during healing. Dressing changes were limited to twice weekly instead of 3 times daily.

This case demonstrates the feasibility of an underdescribed application for a new mechanically powered ambulatory negative pressure device. Findings from this case study suggest that this device may be clinically applicable for patients undergoing ostomy takedown in the United States and in developing nations such as Haiti.
