[Current status of treatment of appendicitis. Results of 2 prospective multicenter studies in East Germany. East German Working Group "Outcome Assessment and Quality Assurance in Surgery" of the CAQ of the German Society of Surgery].

In a period of 10 years we carried out two prospective multicentric trials to evaluate the state of the art in treatment of appendicitis. One study was performed before introduction of laparoscopy. Important criteria like new diagnostic methods (sonography, laparoscopy), frequency of operation, perforation rate, frequency of appendectomies in case of non acute inflammation and postoperative complications were compared.
