Causes of acute abdomen, preferred imaging methods, and prognoses in geriatric patients presenting to the emergency department with abdominal pain.

Objective: Abdominal pain is one of the most common reasons for admission to the emergency department in the geriatric population. The aim of this study was to investigate the diseases frequently detected in elderly patients diagnosed with acute abdomen in the emergency department, the imaging methods used in the diagnostic processes of these diseases, and the prognosis of the patients.

Methods: In all, 175 patients who visited the emergency department due to abdominal pain and were hospitalized with a diagnosis of acute abdomen were evaluated. The patients were categorized into seven groups according to their diagnosis as biliary diseases, pancreatitis, appendicitis, gastrointestinal system perforation, ileus, mesenteric ischemia, and atypical causes.

Results: The mean age of the patients was 76.3±7.7 years (range 65-93), and 96 (54.9%) were women. The most common causes of acute abdomen were biliary diseases and pancreatitis. Ultrasonography (88.6%) was the most frequently preferred imaging method in the emergency department, and it was most frequently used for biliary diseases. Notably, 20 (11.4%) patients were treated in the intensive care unit, and 9 (5.1%) patients died.

Conclusion: The most common causes of acute abdomen in the geriatric population were biliary diseases and pancreatitis, and ultrasonography imaging was the most common choice for the diagnosis of these diseases. In elderly patients with abdominal pain, rapid and accurate diagnosis and selection of the correct imaging method are extremely important.
