Critical appraisal of laparoscopic lavage for Hinchey III diverticulitis

Table 1 Hinchey classification and stage-adjusted outcomes and therapeutic approaches

Stage	Definition	Mortality (%)	Treatment
I	Small abscess (> 4 cm)	0	iv antibiotics
II	Large (> 4 cm) abscess	5	iv antibiotics + drainage
III	Purulent peritonitis	25	LLD, PA or Hartmann
IV	Fecal peritonitis	50	Hartmann
