2 3E 5E Superior mesenteric artery occlusion with bowel ischemia
3 Not recorded 5 Perforated colon with sepsis. Moribund
4 4 3 Reviewer used subsequent cases after complications instead of index case
5 4 3 Several severe systemic comorbidities (poorly controlled diabetes, chronic obstructive pulmonary disease, asthma), but none were a constant threat to life
