TC-325 is a novel endoscopic hemostatic powder. Our aim was to describe a single-center experience with the use of TC-325 in the upper and lower gastrointestinal tract, while for the first time attempting to determine how long the powder remains on a lesion.
The charts of consecutive patients receiving TC-325 therapy between July 2011 and July 2013 were reviewed retrospectively. Primary endpoints included immediate hemostasis and early rebleeding (≤ 72 hours).
Overall, 60 patients received 67 treatments with TC-325: 21 for nonmalignant nonvariceal upper gastrointestinal bleeding, 19 for malignant upper gastrointestinal bleeding, 11 for lower gastrointestinal bleeding, and 16 for intra-procedural bleeding. Immediate hemostasis was achieved in 66 cases (98.5 %), with 6 cases (9.5 %) of early rebleeding. No serious adverse events were noted. No TC-325 powder was identified in the 11 patients who underwent second-look endoscopy, performed within 24 hours in 4 patients.
TC-325 appears safe and effective for managing bleeding in the upper and lower gastrointestinal tract with a variety of causes. The time during which the powder remains in the gastrointestinal tract is short, with complete elimination from the gastrointestinal tract as early as within 24 hours after use.
TC-325 是一种新型的内镜止血粉。我们的目的是描述在上下消化道中使用 TC-325 的单中心经验,同时首次尝试确定粉末在病变部位停留的时间。
回顾性分析了 2011 年 7 月至 2013 年 7 月期间连续接受 TC-325 治疗的患者的病历。主要终点包括即刻止血和早期再出血(≤72 小时)。
共有 60 例患者接受了 67 次 TC-325 治疗:21 例用于非恶性非静脉曲张性上消化道出血,19 例用于恶性上消化道出血,11 例用于下消化道出血,16 例用于术中出血。66 例(98.5%)即刻止血成功,6 例(9.5%)早期再出血。无严重不良事件发生。在 11 例接受 24 小时内进行的第二内镜检查的患者中,未发现 TC-325 粉末。
TC-325 似乎对治疗各种原因引起的上下消化道出血安全有效。粉末在胃肠道中的停留时间很短,在使用后 24 小时内即可从胃肠道完全清除。
