A new hemostatic adhesive powder (UI-EWD) has been developed to reduce the high re-bleeding rates associated with the currently available hemostatic powders. The current study aimed to assess the efficacy of UI-EWD as a salvage therapy for the treatment of refractory upper gastrointestinal bleeding (UGIB).
A total of 17 consecutive patients who had failed to achieve hemostasis with conventional endoscopic procedures and had undergone treatment with UI-EWD for endoscopic hemostasis in refractory UGIB were prospectively enrolled in the study. We evaluated the success rate of initial hemostasis and rate of re-bleeding within 30 days.
All patients underwent successful UI-EWD application at the bleeding site. Initial hemostasis occurred in 16/17 patients (94 %). Re-bleeding within 30 days occurred in 3/16 patients (19 %) who had achieved initial hemostasis. In the second-look endoscopy after 24 hours, hydrogel from UI-EWD was found attached at the bleeding site in 11/16 patients (69 %).
UI-EWD has a high success rate for initial hemostasis in refractory UGIB and shows promising results in the prevention of re-bleeding.
一种新型止血黏附粉（UI-EWD）已被开发出来，以降低目前可用的止血粉相关的高再出血率。本研究旨在评估 UI-EWD 作为治疗难治性上消化道出血（UGIB）的挽救性治疗的疗效。
本研究前瞻性纳入了 17 例连续接受常规内镜治疗未能止血且接受 UI-EWD 内镜止血治疗的难治性 UGIB 患者。我们评估了初始止血的成功率和 30 天内再出血的发生率。
所有患者均在出血部位成功应用 UI-EWD。16/17 例患者（94%）达到初始止血。在 16 例达到初始止血的患者中，有 3 例（19%）在 30 天内再次出血。在 24 小时后的第二次内镜检查中，11/16 例（69%）患者的出血部位发现 UI-EWD 的水凝胶附着。
UI-EWD 治疗难治性 UGIB 的初始止血成功率高，在预防再出血方面显示出良好的效果。
