Aims: Laparoscopic appendectomy (LA) for acute appendicitis (AA) is one of the most performed procedures. The effects of peritoneal lavage (PL) and the reasons to perform it have not been cleared and all meta-analyses didn’t show a statistical advantage to prevent infectious complications. This study aims to investigate surgeons’ perceptions during LA, comparing intraoperative findings with histological results, and exploring how surgeons’ subjectivity influences the decision-making process on PL. Methods: Data were extracted from the two-year data lock from REsiDENT-1 registry, a prospective resident-led multicentre observational trial. This study investigates the relationships between PL and postoperative intraabdominal abscesses (pIAA) introducing a classification for AA to standardize the intraoperative grading. We included pre, intra, and postoperative variables. We applied our classification proposal, used a five-point Likert scale (Ls) to assess subjective LA difficulty and ran a concordance analysis between the assessment of AA and histology. Subsequently, a multivariate logistic regression model was built to find factors influencing PL. Results: 561 patients were enrolled from twenty-one hospitals and 51 residents. 542 procedures were included in the logistic regression analysis and 441 in the concordance analysis, due to missing data. PL was used in 222 LA (39, 6%). We discovered a moderate positive monotonic relationship between surgical evaluation and histology, p < 0.001. Despite this, the reliability of the surgeon’s assessment of appendicitis is progressively lower for gangrenous and perforated forms. The increasing grade of contamination, the increasing grade of subjective difficulty and the intraoperative finding of a gangrenous or perforated appendicitis were independent predictors of PL. Conclusion: This study shows how surgeons’ evaluation of AA severity overestimated more than half of gangrenous or perforated appendices with the perception of a challenging procedure. These perceptions influenced the choice of PL. We proved that the evaluation during LA could be affected by subjectivity with a non-negligible impact on the decision-making process.

Abstract
Aims: Laparoscopic appendectomy (LA) for acute appendicitis (AA) is one of the most performed procedures. The effects of peritoneal lavage (PL) and the reasons to perform it have not been cleared and all meta-analyses didn’t show a statistical advantage to prevent infectious complications. This study aims to investigate surgeons’ perceptions during LA, comparing intraoperative findings with histological results, and exploring how surgeons’ subjectivity influences the decision-making process on PL. Methods: Data were extracted from the two-year data lock from REsiDENT-1 registry, a prospective resident-led multicentre observational trial. This study investigates the relationships between PL and postoperative intraabdominal abscesses (pIAA) introducing a classification for AA to standardize the intraoperative grading. We included pre, intra, and postoperative variables. We applied our classification proposal, used a five-point Likert scale (Ls) to assess subjective LA difficulty and ran a concordance analysis between the assessment of AA and histology. Subsequently, a multivariate logistic regression model was built to find factors influencing PL. Results: 561 patients were enrolled from twenty-one hospitals and 51 residents. 542 procedures were included in the logistic regression analysis and 441 in the concordance analysis, due to missing data. PL was used in 222 LA (39, 6%). We discovered a moderate positive monotonic relationship between surgical evaluation and histology, p < 0.001. Despite this, the reliability of the surgeon’s assessment of appendicitis is progressively lower for gangrenous and perforated forms.
