Nasogastric Tubes in 2026: Use Them Selectively, Remove Them Early: JAMA Surgery August | 2026.

Key Takeaways

NG tubes remain most valuable for decompression, particularly in small-bowel obstruction (SBO), severe gastric distension, vomiting, ileus, or impaired gastrointestinal propulsion.

Why decompression works: the gastrointestinal tract normally handles several litres of secretions daily.

Obstruction/ileus → impaired forward flow and absorption → fluid accumulation → bowel distension, vomiting and aspiration risk → NG decompression reduces intraluminal volume and pressure.

In uncomplicated adhesive SBO, NG decompression remains an important component of conservative management alongside bowel rest, intravenous fluids, electrolyte correction and close clinical monitoring.

Water-soluble contrast is primarily useful diagnostically. Passage of contrast into the colon helps predict successful non-operative resolution; convincing evidence for a true therapeutic effect is less certain.

A major change is occurring in postoperative care: routine prophylactic NG decompression after elective gastrointestinal surgery is increasingly discouraged.

ERAS philosophy: early oral intake + early mobilisation + fewer unnecessary tubes. Routine NG placement has not convincingly reduced anastomotic leak and may delay bowel recovery while increasing discomfort and some pulmonary complications.

Selective postoperative NG use remains appropriate for persistent vomiting, major gastric distension, clinically significant ileus, delayed gastric emptying or high aspiration risk.

Placement safety is critical: advance gently along the nasal floor and never force the tube against resistance. Air insufflation with auscultation is unreliable for confirming placement.

Before feeding or administering medication through an NG tube, correct intragastric positioning must be confirmed, commonly radiographically when required.

Prolonged suction can cause volume depletion, hypokalaemia and metabolic alkalosis; NG output, hydration and electrolytes therefore require active monitoring.

GastroAGI Bottom Line

The modern principle is no longer “NG tube by default.” It is “NG tube for a clear indication, safe placement, daily reassessment and removal at the earliest appropriate opportunity.”
