Title: Hemostatic Efficacy and Safety of the Hemostatic Powder UI-EWD in Patients with
Lower Gastrointestinal Bleeding
Version: 3 Date: 11 Jan 2022
Reviewer's report:
Cha et al. reported a retrospective cohort of 167 patients with LGIB  with hemoastasis performed
and divide them into convention group vs UI-EWD group to evaluate the efficacy and safety
of UI-EWD group.
Although this should be best evaluated by a randomized prospective study, the current cohort
demonstrated the effectiveness and safety of UI-EWD and form a foundation for further
evaluation.
The authors were able to address some of the interesting findings and provide a reasonable
paucity. For example, more UI-WED were applied for lesions in hepatic flexure and the authors
attributed it to the difficult position for endoscopic hemostasis and the lower perforation rate
due to lower pressure used in UI-WED. The authors also detailly examined the cases with re-
bleeding and provide relevant clinical information to the readers.
Minor comments:
- please be consistent in numbers (one hundred sixty seven patients vs 38 patients)
- include the unit for platelet count in the manuscript
