Mortality associated with emergency abdominal surgery in the elderly

Area of Science:

• Geriatric Surgery
• Surgical Outcomes
• Abdominal Surgery

Background:

• Elderly patients undergoing emergency abdominal surgery face increased morbidity and mortality.
• A study was conducted to analyze mortality factors in this demographic.
• The study compared outcomes between patients aged 70-79 and 80+ years.

Purpose of the Study:

• To identify factors predicting death in elderly patients undergoing emergency abdominal surgery.
• To compare mortality rates between two elderly age groups (70-79 vs. 80+ years).

Main Methods:

• Retrospective and prospective study of 710 patients aged 70+ undergoing emergency abdominal surgery.
• Patients divided into two groups: 70-79 years (n=364) and 80+ years (n=346).
• Analysis included age, sex, perioperative risk, symptom-to-admission interval, diagnosis, operation type, findings, morbidity, mortality, and hospital stay.

Main Results:

• Overall mortality was 22% (19% in 70-79 group, 24% in 80+ group).
• Predictors of death included American Society of Anesthesiologists (ASA) grading, delayed symptom onset to admission, mesenteric infarction, palliative surgery (defunctioning stoma/bypass), and non-therapeutic laparotomy.
• Age group (70-79 vs. 80+) did not significantly impact mortality, morbidity, or length of stay.

Conclusions:

• Mortality in elderly patients with acute abdomen is predictable by perioperative risk (ASA grade), treatment delay, and need for palliative surgery.
• Increasing age (70-79 vs. 80+) is not a significant factor influencing mortality, morbidity, or hospital stay in this population.
