This narrative review covers nasogastric (NG) tube types, indications, placement techniques, and complications — with a focus on their role in small-bowel obstruction (SBO) decompression, post-operative gastrointestinal (GI) surgery use, and prepyloric feeding.
NG tube decompression remains a core management strategy for uncomplicated SBO (without intestinal compromise or peritonitis). Growing evidence supports reducing routine NG tube use after elective GI surgery, though indications remain highly variable and often subjective.
Narrative review format without systematic search or meta-analysis; conclusions on post-operative NG tube use are described as based on 'growing evidence' without quantified outcomes or specific trial data presented in the abstract.
NG tubes are still essential for decompression in uncomplicated SBO, but clinicians should consider reducing their routine use after elective GI surgery, in line with emerging evidence. Placement technique and complication awareness remain important for safe clinical practice.
