Aim: The aim of our study was to evaluate the advantages and disadvantages of open appendectomy versus laparoscopic appendectomy in the surgical treatment of acute appendicitis. We have compared the following items: operating time, postoperative pain, length of hospital stay, postoperative complications and costs.
Methods: The study was conducted on 435 patients admitted in our Department from December 1993 to December 2003 with diagnosis of acute appendicitis: 339 (77.9%) cases were operated with laparoscopic approach (LA group) and 96 (22.1%) cases with open approach (OA group) according to personal experience of surgeons on laparoscopic technique and patient's anthropometrical conformation.
Results: Mean operative time in LA group was 50 minutes (range 25-195) and 65 minutes (range 35-160) for OA group. In 15 patients (4.4%), the operation had to be converted to open approach. The morbidity was observed in 4.4% of patients for the LA group and 14.6% for the OA group. Hospital stay was faster for patients having laparoscopic appendectomy (2.5 days vs 3.5 days). Pain in the 1st and 2nd postoperative days, evaluated on the use of pain medication, was less in patient in LA group whereas the costs were higher in the LA group than in OA group.
Conclusions: In our experience the laparoscopic approach to acute appendicitis can be considered safe and effective with diagnostic and therapeutic value. It significantly offers all the advantages of mini-invasive surgery reported in literature.
