Summary
Appendectomy mortality is significantly higher in elderly patients and those with perforated appendicitis. Increased diagnostic efforts are recommended for frail patients to reduce surgical trauma risks.
Area of Science:
- Surgical Outcomes
- Public Health
- Epidemiology
Background:
- Appendicitis management is debated, with no clear consensus on early surgery versus expectant management.
- Mortality rates following appendectomy are not well-established.
Purpose of the Study:
- To investigate mortality rates and associated risk factors after appendectomy.
- To analyze the case fatality rate (CFR) and standardized mortality ratio (SMR) in relation to age and diagnosis.
Main Methods:
- A comprehensive follow-up of all appendectomies in Sweden (1987-1996) was conducted using register linkage.
- Analysis included 117,424 appendectomies, examining CFR and SMR by discharge diagnosis.
Main Results:
- The overall CFR was 2.44 per 1,000 appendectomies, with significant increases in elderly patients and those with perforated appendicitis.
- Standardized mortality ratios indicated a sevenfold excess death rate post-appendectomy compared to the general population.
- Common causes of death included appendicitis, ischemic heart disease, tumors, and gastrointestinal diseases.
Conclusions:
- Appendectomy carries a high case fatality rate, particularly in elderly individuals.
- Surgical trauma may contribute to excess deaths in patients with nonperforated appendicitis and nonsurgical abdominal pain.
- Enhanced diagnostic evaluation is advised for frail patients with equivocal appendicitis symptoms over immediate surgery.
