Introduction of laparoscopic appendectomy: a retrospective comparison with the open technique

Laparoscopic appendectomy (LA) is gaining favour as an alternative to the traditional laparotomic technique (OA) despite the persistence of controversy regarding indications, morbidity, hospital stay, costs and surgical time. We present a retrospective analysis of our first three years of experience with the procedure. During this period we performed 235 appendectomies (102 laparoscopic and 133 laparotomic). The conversion rate was 9.7%, due to severe peritonitis, high-grade inflammation and an unfavorable position of the appendix; we found a significantly higher percentage of difficulty due to these factors in the laparotomic procedures. Operating time was similar in the two groups. The rate of associated pathology was higher (22.5% vs 6%) after laparoscopy, but conversion to laparotomy was never necessary for treatment. Early morbidity was limited to 2 patients who underwent laparoscopic appendectomy (1 re-operation for a micro-abscess and 1 conservatively treated haemorrhage), while wound infections (13.5% vs 1.9%) and incisional hernias (0% vs 2.3%) were more frequent in the open procedures. Hospital stay was slightly less in the laparoscopic group (4.0 vs 4.7 days). In our initial experience, laparoscopic appendectomy has shown significant advantages in terms of intraoperative diagnosis of associated diseases and diminished morbidity. We advocate a laparoscopic approach to appendicular disease, reserving conversion to laparotomy for selected cases after exploration.
