A 58-year-old man presents to the emergency department with 3 days of progressive left lower quadrant abdominal pain and a subjective fever. His temperature is 38.1°C (100.6°F), blood pressure is 130/80 mm Hg, and heart rate is 88/min. Abdominal examination reveals localized tenderness in the left lower quadrant but no rigidity, rebound, or guarding. Laboratory studies show a leukocyte count of 13,000/mm³. Arrange the following management steps in the most appropriate chronological order for this patient.
- 1Obtain a computed tomography (CT) scan of the abdomen and pelvis with contrast.
- 2Initiate a clear liquid diet and a course of oral antibiotics.
- 3Discharge the patient home with explicit return precautions.
- 4Schedule a colonoscopy for 6 to 8 weeks later.
Cevap
The correct sequence is to first obtain a CT scan to confirm uncomplicated diverticulitis, then initiate medical management with antibiotics and a clear liquid diet, followed by safe discharge home, and finally scheduling a follow-up colonoscopy in 6 to 8 weeks.
The standard of care for suspected acute diverticulitis starts with diagnostic confirmation via CT scan. Once confirmed as uncomplicated, the patient is treated medically with bowel rest (liquid diet) and antibiotics. Because the patient is stable and uncomplicated, they can be safely discharged. Finally, a follow-up colonoscopy is mandatory 6-8 weeks later to rule out colorectal cancer once the risk of iatrogenic perforation has passed.
