Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Postoperative Intrabdominal Abscess
Surgical site infections are divided into three categories: superficial incisional SSI,deep incisional SSI and organ/space surgical site infection.O/S SSI must meet the following criteria;date of event within 30 days after surgical procedure,involvement of any part of the body deeper than the fascial/muscle layers that are opened or manipulated during the operative procedure.At least one of the following:purulent drainage from a drain that is placed into the organ/space (eg;closed suction drainage system,open drain,T-tube drain,CT-guided drainage).Organism(s) identified from fluid or tissue in the organ/space by a culture- or non-culture-based microbiologic testing method which is performed for purposes of clinical diagnosis or treatment.An abscess or other evidence of infection involving the organ/space that is detected on the gross anatomical or histopathologic exam,or imaging test evidence suggestive of infection
90 days after surgery
Secondary Outcomes (1)
Postoperative complication

patients affected by acute appendicitis undergoing totally laparoscopic appendectomy
Interventions
This study aims to investigate the impact of laparoscopic lavage on the incidence of postoperative abscesses stratifying patients on the grade of appendicitis and peritoneal contamination.
