Laparoscopic stapler appendectomy : A prospective study of 267 consecutive cases

The value of laparoscopic appendectomy remains controversial. Therefore, we investigated the accuracy of diagnostic laparoscopy in detecting acute appendicitis and tested the applicability and safety of stapling appendectomy as a routine procedure. Data from 267 consecutive patients with suspicion of acute appendicitis were recorded prospectively. Histopathological examination revealed nonperforated and perforated appendicitis in 63.3% and 13.1%, respectively, and no inflammation in 10.8%. Other pathological findings were observed in 12.7%. Diagnostic laparoscopy detected appendicitis with a sensitivity and specificity of 95.6% and 96.6%, respectively; the positive and negative predictive value were 99.5% and 74.3%, respectively. Morbidity was 10.2% in total and 40% for perforated appendicitis. Planned laparoscopic reexploration reduced morbidity by 23.4% in patients with perforated appendicitis and substantial peritonitis. Mortality was 0.4%. Laparoscopy improves diagnostic accuracy for acute appendicitis and laparoscopic stapling appendectomy is a safe and efficient procedure for all forms of appendicitis.
