Influence of sarcopenia and frailty in the management of elderly patients with acute appendicitis.

In developed countries, the average life expectancy has been increasing and is now well over 80 years. Increased life expectancy is associated with an increased number of emergency surgical procedures performed in later age groups. Acute appendicitis is one of the most common surgical diseases, with a lifetime risk of 8%. A growing incidence of acute appendicitis has been registered in the elderly population and in the oldest groups (> 80 years). Among patients > 50-year-old who present to the emergency department for acute abdominal pain, 15% have acute appendicitis. In these patients, emergency surgery for acute appendicitis is challenging, and some important aspects must be considered. In the elderly, surgical treatment outcomes are influenced by sarcopenia. Sarcopenia must be considered a precursor of frailty, a risk factor for physical function decline. Sarcopenia has a negative impact on both elective and emergency surgery regarding mortality and morbidity. Aside from morbidity and mortality, the most crucial outcomes for older patients requiring emergency surgery are reduction in function decline and preoperative physical function maintenance. Therefore, prediction of function decline is critical. In emergency surgery, preoperative interventions are difficult to implement because of the narrow time window before surgery. In this editorial, we highlight the unique aspects of acute appendicitis in elderly patients and the influence of sarcopenia and frailty on the results of surgical treatment.
