The introduction of negative pressure wound therapy has improved open abdomen treatment in a wide range of ways. Unfortunately, the handling of intestinal fistulae remains a serious problem. Suction, applied via a sponge to the wound surface, often results in enlargement of the fistula or eventration of the mucosa. In addition, viscous stool can obstruct the sponge, resulting in separation of the sponge and wound surface. The suction becomes insufficient and may lead to contamination or infection of the wound.
This was the reason for our development of four new types of fistula adapters for the management of enteroatmospheric fistulae in cooperation with doctors at University Hospital Magdeburg.
