Abstract
AIM: To compare outcomes using the novel portable
endoscopy with that of nasogastric (NG) aspiration in
patients with gastrointestinal bleeding.
METHODS: Patients who underwent NG aspiration for
the evaluation of upper gastrointestinal (UGI) bleed-
ing were eligible for the study. After NG aspiration, we
performed the portable endoscopy to identify bleeding
evidence in the UGI tract. Then, all patients underwent
conventional esophagogastroduodenoscopy as the
gold-standard test. The sensitivity, specificity, and ac-
curacy of the portable endoscopy for confirming UGI
bleeding were compared with those of NG aspiration.
RESULTS: In total, 129 patients who had GI bleeding
signs or symptoms were included in the study (age
64.46 ± 13.79, 91 males). The UGI tract (esophagus,
stomach, and duodenum) was the most common site
of bleeding (81, 62.8%) and the cause of bleeding
was not identified in 12 patients (9.3%). Specificity for
identifying UGI bleeding was higher with the portable
endoscopy than NG aspiration (85.4% vs 68.8%, P =
0.008) while accuracy was comparable. The accuracy
of the portable endoscopy was significantly higher
than that of NG in the subgroup analysis of patients
with esophageal bleeding (88.2% vs 75%, P = 0.004).
Food material could be detected more readily by the
portable endoscopy than NG tube aspiration (20.9% vs
9.3%, P = 0.014). No serious adverse effect was ob-
served during the portable endoscopy.
CONCLUSION: The portable endoscopy was not su-
perior to NG aspiration for confirming UGI bleeding
site. However, this novel portable endoscopy device
might provide a benefit over NG aspiration in patients
with esophageal bleeding.
