Effect of laparoscopy on bacteremia in acute appendicitis: a randomized controlled study.

Laparoscopic appendectomy is increasingly used in treating acute appendicitis. Several controlled series have demonstrated the clinical benefit of the procedure. However, some basal pathophysiologic changes caused by the laparoscopy still need clarification, i.e., whether laparoscopy can give rise to bacteremia. The purpose of this randomized controlled study in 30 patients undergoing surgery due to suspected acute appendicitis, either by an open classic technique or by a laparoscopic technique, was (by collecting samples for blood culturing pre-, peri-, and postoperatively) to evaluate whether laparoscopy during carbon dioxide pneumoperitoneum could induce bacteremia. Six patients of 12 in the group treated by laparoscopy presented positive blood cultures peri- and postoperatively. No positive blood cultures were demonstrated in the open operated group. The difference was significant (P = 0.0183). The clinical significance of these findings should be clarified in further clinical investigations.
