Key result
Patients aged 90 years or older undergoing abdominal surgery had a significantly higher 30-day postoperative mortality rate compared to those under 90 years of age (15.2% vs 1.9%, p<0.05).

Does age ≥90 years increase postoperative morbidity and mortality in patients undergoing abdominal surgery?
Abdominal surgery in patients aged 90 years or older is associated with significantly higher postoperative morbidity and mortality, particularly in those with preoperative comorbidities and postoperative pulmonary complications.
Supports preoperative counseling on elevated mortality risk for abdominal surgery in nonagenarians; leaves open whether frailty assessment improves outcomes.

Tanaka et al. (2008) conducted a cohort in Abdominal surgery (n=1,835). Age ≥90 years vs. Age <90 years was evaluated on 30-day postoperative mortality (p=<0.05). Patients aged 90 years or older undergoing abdominal surgery had a significantly higher 30-day postoperative mortality rate compared to those under 90 years of age (15.2% vs 1.9%, p<0.05).
