Endoscopic hemostasis performed in the emergency room is difficult due to the presence of blood clots and food residue that makes obtaining a clear view of the bleeding vessel difficult. We experienced the efficacy of a newly developed inverted overtube to shorten the hemostatic time and obtain a clear endoscopic view with upper gastrointestinal bleeding patient who were transferred by ambulance car and required emergency endoscopy. The technique improved the endoscopic views and enabled us to perform the hemostatic procedures from the conventional standing position while freely and easily changing the patient's position. The presence of blood clots and food residue in the gastric fornix or upper gastric body makes identifying a bleeding exposed vessel impossible. This set-up significantly shortened the procedure time. The inverted overtube helped us obtain a clear view in patients who were laid in the right lateral position. Rapid identification of exposed vessels resulted in success of hemostasis.
由于血液凝块和食物残渣的存在，使得在急诊室进行内镜止血变得困难，这使得难以清晰观察到出血血管。我们在一名因上消化道出血而被救护车转送来并需要紧急内镜检查的患者身上，体验了一种新开发的反置外套管的疗效。该技术改善了内镜视野，并使我们能够在自由、轻松地改变患者体位的情况下，从常规站立位进行止血操作。血液凝块和食物残渣存在于胃窦或胃上部，使得难以识别暴露的出血血管。这种设置显著缩短了手术时间。反置外套管帮助我们在右侧卧位的患者中获得清晰的视野。迅速识别暴露的血管有助于止血成功。
