In partial small bowel obstruction, which initial management steps are appropriate?

• A. Decompress the GI tract with an NG tube, administer IV fluids, prohibit oral intake
• B. Immediate surgical exploration
• C. Start oral feeding
• D. Use laxatives to relieve obstruction

Answer: (A)

When a partial small bowel obstruction is suspected, the goal is to stabilize the patient and rest the bowel while assessing for potential deterioration. The best first step is to decompress the gastrointestinal tract with a nasogastric tube to relieve distension and reduce vomiting, give the bowel a chance to recover, and prevent aspiration. Simultaneously, ensure reliable IV access and start isotonic fluids to correct dehydration and any electrolyte disturbances that often accompany obstruction. Keeping the patient NPO avoids further burden on the bowel and prevents aspiration during vomiting or potential anesthesia if surgery becomes necessary.

This conservative, decompressive approach buys time to see if the obstruction resolves without surgery and allows for close monitoring for warning signs such as increasing abdominal pain, fever, leukocytosis, or signs of peritonitis or strangulation. Oral intake is avoided initially because feeding can worsen distension and risk aspiration, and laxatives would do the opposite of what’s needed by stimulating bowel movement when the goal is rest and decompression. Immediate surgery is reserved for emergencies or for failure of nonoperative management, not for all partial obstructions.
