Laparoscopic stapler appendectomy. A prospective study of 267 consecutive cases
Background:
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.
Methods:
Data from 267 consecutive patients with suspicion of acute appendicitis were recorded prospectively.
Results:
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%.
Conclusions:
Laparoscopy improves diagnostic accuracy for acute appendicitis and laparoscopic stapling appendectomy is a safe and efficient procedure for all forms of appendicitis.
