According to the modified Hinchey classification of complicated diverticulitis, generalised purulent peritonitis corresponds to which stage?
- A Hinchey stage I
- B Hinchey stage II
- C Hinchey stage III ✓
- D Hinchey stage IV
Correct answer: C. Hinchey stage III
Explanation
Hinchey stage I is pericolic abscess, stage II is pelvic or distant intra-abdominal abscess, stage III is generalised purulent peritonitis from a sealed-off microscopic perforation, and stage IV is faeculent peritonitis from a free perforation communicating with the bowel lumen. The distinction matters because stage III disease may be managed by laparoscopic lavage in selected patients, whereas stage IV generally demands resection and control of contamination.
