Laparoscopic versus open appendectomy for complicated appendicitis in high risk patients

Laparoscopic appendectomy is widely used for the treatment of complicated appendicitis. Its use in patients with high operative risk is still on debate. The aim of the presented study was to investigate the benefits of laparoscopic appendectomy in patients with high peri- and postoperative risk factors.
We performed a retrospective analysis of all patients who underwent appendectomy in our center between 2006 and 2013. Patients were classified according to their preoperative risk (classification of the American Society of Anesthesia—ASA score). Only patients with ASA 3 and 4 were included and were divided into two groups—open appendectomy (OA group) and laparoscopic appendectomy (LA group).
The operation time was slightly longer in the LA group (p = 0.05), but hospital stay was shorter (p = 0.05). Complications graded according to the Clavien Dindo classification were slightly more frequent in patients after LA, whereas severe complications occurred more frequently in patients after OA (p = 0.01). The postoperative WBC decreased steadily and significantly in patients after OA, whereas the decrease in patients after LA was delayed (p = 0.03). CRP slightly increased after OA and decreased thereafter, whereas it steadily decreased after LA (p = 0.05).
Laparoscopic appendectomy can be recommended for patients with complicated appendicitis even with higher risk categories.
