Fistula is an abnormal hollow space or a connection between two such spaces or hollow organs. Fistulae can occur naturally or as a consequence of a surgery. Congenital fistula results from developmental defects while acquired fistulae may occur as a result of a disease.
Complicated wounds can also lead to fistula formation (eg. tracheostomy tubes, ostomy pouches, diabetic foot, rectovaginal fistula). Pancreatic, biliary, duodenal fistulas or a fistula of large intestine are the examples of an ostomy.
Fistula is the kind of wound which is more difficult to dress and require several-layer dressings of diverse properties and a specialist type of protection.
The fistula depth could be examined with a probe, X-Ray, computer tomography or magnetic resonance imaging. Fistula treatment is determined by its cause and kind as well as by treatment possibilities.
Photo gallery of cases:
Patient 1. – A 76-year-old patient after laparoscopy with a complicated wound around the navel.
The post-surgery wound was bathed on its surface and rinsed to the abdominal walls. Gauze pads were used as the dressing which was changed 2-3 times a day.
Photo. 1. Before treatment
We examined the wound which appeared to be a fistula of 25 cm in depth. The wound was sampled for culture, absorbent and lining dressings were used and devitalized tissue was gradually removed.

Inflammation exudate was eliminated and the fistula was prepared for fluid removal from the peritoneal cavity.
