[Causes of development of peritonitis after appendectomy].

According to the authors' data peritonitis developed after appendectomy in 122 of 18347 patients, operated upon for acute appendicitis, was an extremely grave complication of this lesion and the related surgical intervention. The main causes for development of postoperative peritonitis were local and diffuse peritonitis (101 cases), more rarely--technical and tactical errors made during the operation. Due to diagnostic difficulties a purposeful treatment for postoperative peritonitis was undertaken with a delay, reoperations were performed in late terms and not in every case either. The mortality due to postoperative peritonitis made 23 per cent.
