A very important paper by Young-II Kim et al. [1] was published recently in Endoscopy. The authors found that the Glasgow-Blatchford score (GBS) was inferior to the Rockall score in predicting the need for urgent hemostatic intervention for tumor-associated upper gastrointestinal bleeding (UGIB), leading to poor performance (area under the receiver operating characteristic curve [AUROC] 0.56). This study is crucial for patient risk stratification for UGIB during the COVID-19 pandemic, and we would like to draw your attention toward it.

The COVID-19 pandemic has severely affected the practice of gastrointestinal (GI) endoscopy worldwide because upper GI endoscopy has been recognized as an aerosol-generating procedure that increases the risk of COVID-19 infection [2]. Thus, the endoscopic management of patients with UGIB now presents a dilemma. The pre-endoscopy risk scores, such as GBS, are based on pre-pandemic research and have not been validated by large-scale studies during the COVID-19 pandemic. A recent case series [3] has shown that six UGIB patients with COVID and GBS > 7 did not require endoscopy and were conservatively managed, which did not accord with the relevant European Society for Gastrointestinal Endoscopy (ESGE) guideline [4]. The latter recommends only that patients with a GBS score of 0 – 1 do not require endoscopy. Thus, the performance of the GBS has seemed to be especially limited during the COVID-19 pandemic [3]. According to Laursen et al. [5], the low-risk threshold for defining UGIB patients who do not require inpatient endoscopy and hospitalization could be increased to GBS < 3.

In conclusion, the COVID-19 pandemic remains a worldwide challenge, and its impact on GI endoscopy and UGIB detection could be increasingly significant. Raising the GBS threshold or developing a new and accurate risk score before endoscopy in UGIB patients will be critical in the prevention of a UGIB healthcare crisis. We hope a more rigorous study will be conducted in the near future.
