Nonoperative management without nasogastric tube decompression for adhesive small bowel obstruction

Abstract

Background

Although nasogastric tube (NGT) decompression is widely used in nonoperative management for adhesive small bowel obstruction (SBO), robust evidence is lacking to support this routine practice.

Methods

Patients who received nonoperative management with a diagnosis of adhesive SBO were retrospectively reviewed. Those who received NGT or long-tube decompression at admission were categorized into the NGT group, while those who initially had no NGT placement were categorized into the non-NGT group. The incidence of vomiting after admission, pneumonia after admission, and the need for surgery were compared.

Results

Among 288 patients, 148 (51.3%) had non-NGT conservative treatment. There were no significant differences in the incidence of vomiting (NGT vs non-NGT: 12.9% vs 18.9%, p = 0.16), pneumonia (1.4% vs 0%, p = 0.235), or need for surgery (12.9% vs 7.4%, p = 0.126).

Conclusions

While NGT decompression is a standard of care for adhesive SBO, selective NGT insertion for patients with persistent nausea or vomiting can become an option.
