REsiDENT 1 (Re-assessment of Appendicitis Evaluation during laparoscopic appendectomy: Do we End a Non-standardized Treatment approach and habit?): peritoneal irrigation during laparoscopic appendectomy—does the grade of contamination matter? A prospective multicenter resident-based evaluation of a new classification system

Table 1 Proposal of classification

Appendix aspect
Erythematous and edematous appendix^a
Appendiceal phlegmon^b
Gangrenous appendix^c
Perforated appendix^d
Contamination

Multiple abscesses
Localized purulent peritonitis
Diffuse purulent peritonitis
Localized fecal peritonitis
Diffuse fecal peritonitis

^aNeutrophils within mucosa and submucosa with mucosal
^bNeutrophilic infiltration of mucosa, submucosa, and muscolaris propria. Transmural inflammation, extensive ulceration, and intramural abscess; vascular thrombosis
^cTransmural inflammation with areas of necrosis; extensive mucosal ulceration
