A 52-year-old male with a surgical history of an open appendectomy 10 years ago presents with severe, colicky abdominal pain, intractable vomiting, and failure to pass flatus for the past 24 hours. Vital signs reveal a heart rate of 105/min and blood pressure of 115/75 mmHg. Examination shows a distended, tympanitic abdomen without rebound tenderness or guarding. Arrange the following interventions in the most appropriate chronological order for his initial evaluation and management.
- 1Initiate nil per os (NPO) status and begin intravenous fluid resuscitation.
- 2Insert a nasogastric tube to decompress the upper gastrointestinal tract.
- 3Obtain a computed tomography (CT) scan of the abdomen and pelvis.
- 4Admit the patient to the surgical service for nonoperative management and serial clinical examinations.
Cevap
The correct sequence is to first initiate NPO status and IV fluids, then insert a nasogastric tube, followed by obtaining a CT scan, and finally admitting the patient for serial examinations.
The standard sequence for managing a stable patient with a suspected uncomplicated small bowel obstruction is to first address their volume status (NPO and IV fluids). Next, a nasogastric tube should be placed to relieve the symptoms of obstruction and prevent pulmonary aspiration. Once stabilized and decompressed, it is safe to transport the patient for a CT scan to confirm the diagnosis and verify that there is no bowel compromise. Finally, because there is no evidence of peritonitis, the patient is admitted for conservative, nonoperative management.

Anahtar Kavram
The initial management of an uncomplicated small bowel obstruction strictly prioritizes hemodynamic stabilization, followed by symptomatic bowel decompression, diagnostic imaging, and finally, nonoperative observation.
