[Treatment of ligature fistulas after appendectomy]

On the basis of clinical examples, the danger of ambulatory treatment of a ligature fistula is shown. To prevent its development, a care of tissues is necessary: in cases of technical difficulties, a wound should be widened, fat and muscles isolated, a wound before closure needs mandatory irrigation with antiseptic solutions. Ineffectiveness of conservative treatment of a fistula during 1-2 weeks requires the operative intervention in a specialized department with excision of purulent necrotic masses and ligature which maintains the inflammation. Before wound closure, a perforated drain for flowing irrigation should be established.
