Akute Appendizitis - Klinische Versorgungsforschung zur aktuellen chirurgischen Therapie

Abstract

With about 135,000 operations every year appendectomy is one of the most frequent surgical operations in Germany. Acute appendicitis has shown changes in diagnosis and therapy with time. The status of the laparoscopic appendectomy has had to be redefined recently. The aim of this study was to make an analysis of the current surgical therapy for appendicitis and the individual procedures. Three prospective multi-centre quality assurance studies (1988 / 89, 1996 / 97; 2008 / 09) of the "An-Institut" acquired 17,732 treatments from all supply levels of Germany. The average age of patients increased within of the three studies from 25.7 to 34.6 years. Within the studies in 1996 / 97 and in 2008 / 09 the share of laparoscopic appendectomy advanced from 33.1 to 85.8 percent. In the study from 2008 / 09 the laparoscopic appendectomy showed a significant advantage over the conventional technique in terms of wound-healing disturbances (p < 0.001) and a clinical duration of stay (p < 0.001). At no stage of the appendix inflammation did the laparoscopic appendectomy lead to a significant increase of intraabdominal abscesses. Compared with the conventional technique the operating time was shorter (46.6 min vs. 53.5 min). Currently the use of a stapler is the mostly frequently applied method of appendiceal stump closure (83.6 percent). The laparoscopic appendectomy is the most common method of current operative therapy. In comparison to former publications, there is no proof of any disadvantages of laparoscopic appendectomy.
