Clinical presentation of acute appendicitis in elderly patients?
- Acute appendicitis in older patients can be difficult to diagnose because many patients delay seeking care and the presentation is often atypical.
- Elderly patients usually present with vague lower abdominal pain, but on clinical examination, localized right lower quadrant (RLQ) tenderness is not as common as in younger patients.
- A history of periumbilical pain migrating to the right lower quadrant is reported infrequently. Classic signs such as fever, leukocytosis, and localized tenderness may be mild or absent.
In adults, especially the elderly, it is important to consider other regional inflammatory conditions in the differential diagnosis. These include:
- Pyelonephritis: Pain and tenderness located in the flank, accompanied by high fever, elevated white blood cell count, and pyuria.
- Colitis: Often presents with diarrhea; pain typically follows the trajectory of the colon.
- Right-sided diverticulitis: Has an insidious onset, worsens over several days, and usually presents with a broader area of tenderness in the right lower abdomen than appendicitis.
- Other important differentials include malignancies of the gastrointestinal or reproductive systems, perforated peptic ulcers, and cholecystitis.
Computed tomography (CT) is a very valuable diagnostic tool in elderly patients with abdominal pain. It has improved the accuracy of diagnosis and significantly reduced preoperative delays.
Note: In elderly patients, perforation of the appendix occurs more frequently due to delays in diagnosis and operative intervention.
