[Abdominal pain].

Abdominal pain is a symptom that determines the accuracy and timeliness of diagnosis, treatment, and prognosis. The article describes the causes of acute and chronic abdominal pain, particularly the pain in the abdominal wall, and the challenges in recognizing them. The pathogenetic features of visceral, parietal, referred, and psychogenic pain and the principles of symptomatic therapy are addressed. It is emphasized that complex invasive examinations of the abdominal organs are especially relevant for elderly patients who often have conditions that require computed tomography, including contrast-enhanced scans. Without losing the importance of modern examination methods used in clinical practice, the author states that a detailed medical history and a thorough physical examination can significantly narrow the work-up. Endoscopic and other instrumental invasive examinations should be strictly justified and applied with a cost-effective rational approach.
