[Unclear abdominal pain in central emergency admissions. An algorithm]
Abstract:
One of the chief complaints in the emergency department is abdominal pain which is associated with a large spectrum of possible underlying diagnoses. Life-threatening diseases have to be identified urgently to treat them rapidly either conservatively or by surgical intervention. The algorithm presented in this article starts with the triage in the emergency department. After triage the first step in the algorithm is an interdisciplinary communication to start the standardized diagnostic process which includes medical history, clinical examination, laboratory analyses, ultrasound and electrocardiogram. Further diagnostic escalation should be done in unspecific and urgent cases of abdominal pain after consulting a specialist. In approximately 30 % of patients with abdominal pain on admittance to an emergency department the cause remains unclear after undergoing the diagnostic process. In these cases it can be useful for risk stratification to transfer the patient to a ward related to the emergency department for observation und further diagnostics.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Abdominal Regions and Quadrants
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four quadrants...
