Laparoscopic appendectomy is now the treatment of choice in uncomplicated appendicitis. To date its importance in the treatment of complicated appendicitis is not clearly defined.


From January 2005 to June 2013 a total of 1762 patients underwent appendectomy for the suspected diagnosis of appendicitis at our institution. Of these patients 1516 suffered from complicated appendicitis and were enrolled. In total 926 (61 %) underwent open appendectomy (OA) and 590 (39 %) underwent laparoscopic appendectomy (LA). The following parameters were retrospectively analyzed: age, sex, operative times, histology, length of hospital stay, 30-day morbidity focusing on occurrence of surgical site infections, intraabdominal abscess formation, postoperative ileus and appendiceal stump insufficiency, conversion rate, use of endoloops and endostapler.


A statistically significant difference in operative time was observed between the laparoscopic and the open group (64.5 vs. 60 min; p = 0.002). Median length of hospitalization was significantly shorter in the laparoscopic group (p < 0.000). Surgical site infections occurred exclusively after OA (38 vs. 0 patients). Intraabdominal abscess formation occurred statistically significantly more often after LA (2 vs. 10 patients; p = 0.002). There were no statistical significances concerning the occurrence of postoperative ileus (p = 0.261) or appendiceal stump insufficiencies (p = 0.076).


The laparoscopic approach for complicated appendicitis is a safe and feasible procedure. Surgeons should be aware of a potentially higher incidence of intraabdominal abscess formation following LA. Use of endobags , inversion of the appendiceal stump and carefully conducted local irrigation of the abdomen in a supine position may reduce the incidence of abscess formation.
