*Intraoperatively, 27 of these patients had perforated or gangrenous appendicitis, of which 18 had purulent peritonitis; 37 patients were diagnosed as uncomplicated appendicitis, but in 7 of these cases purulent peritonitis was seen
**Intraoperatively, 4 of these patients had a perforated appendix, one a gangrenous appendix and three had uncomplicated appendicitis. In six patients locally or advanced purulent peritonitis was found; in two of the uncomplicated cases no peritonitis was described
