Type: prospective observational multicenter trial. Population of interest: adult patients undergoing laparoscopic appendectomy for acute appendicitis.
Hypothesis : laparoscopic lavage during laparoscopic appendectomy is a practice that should be used in selected patients according to the intraperitoneal grade of contamination and grade of appendicitis. Nonregulated use of laparoscopic lavage cannot be considered superior to suction only considering recent evidence. Few RCT available addressing this issue are available, but any with a high methodological quality.
Aim: The aim of this study is to investigate the impact of laparoscopic lavage during laparoscopic appendectomy on the postoperative incidence of intrabdominal abscesses, stratifying patients in different clusters according to a defined classification considering the intraperitoneal contamination and grade of appendicitis.
