Introduction:

Upper gastrointestinal bleeding occurs in the gastrointestinal tract above the ampulla of Vater. The most frequent causes are peptic ulcers, esophagitis, malignant lesions, vascular lesions such as Dieulafoy’s lesion and angiectasias.

Objective:

To establish which is the best scale to evaluate the risk of bleeding during upper endoscopy.

Method:

Single center, retrospective, descriptive and observational study where Glasgow Blatchford (GBS), pre-endoscopic Rockall and AIMS65 scores were calculated in 62 patients treated at the ISSSTE Tultitlán with the diagnosis of upper gastrointestinal bleeding in the period from January 1 to May 30 2023.

Results:

GBS scores had a mean sample of 10.37 (standard deviation [SD]: 5.11), 100% (n = 62) of the patients had a score ≥ 1. Rockall score had a mean sample of 2.72 (SD: 1.56) and 69.36% (n = 43) of the patients had a score ≥ 2. AIMS65 score had a mean sample of 2.98 (SD: 1.12) and 66.12% (n = 41) of the patients had a score ≥ 3. The GBS score was the one with the higher specificity and positive predictive value.

Conclusions:

GBS score was the one with the higher diagnostic performance for upper gastrointestinal bleeding, it predicts with higher accuracy the necessity to perform upper endoscopy.
