A new endoscopically deliverable bipolar electrocoagulator has been developed, and employed clinically to treat upper gastrointestinal bleeding in 53 patients on 61 occasions. By direct application of the electrode to the bleeding vessels immediate hemostasis was achieved in 52 out of 53 bleeding vessels. Non-bleeding visible vessels were safely coagulated. Arrest of bleeding was permanent in 44 patients (83%), of whom 20 were candidates for emergency operation because of massive, continued or recurrent bleeding. Rebleeding after hemostasis by bipolar electrocoagulation was noted in 8 patients (15%); however, the majority of rebleeds were those with acute mucosal lesions who had serious underlying medical problems. Emergency operation was performed in 5 patients, and was averted in most patients after successful hemostasis by bipolar electrocoagulation. There were no complications related to the procedure. Bipolar electrocoagulation with our coagulator is a safe and easily applicable technique that is a promising addition to currently available endoscopic hemostatic methods.
一种新型的可经内镜输送的双极电凝器已被研发出来，并在临床上用于治疗53例患者的61次上消化道出血。通过将电极直接应用于出血血管，53处出血血管中有52处立即实现了止血。非出血性可见血管也被安全地凝固。44例患者（83%）出血停止且为永久性，其中20例因大量、持续或反复出血而成为急诊手术的候选者。双极电凝止血后有8例患者（15%）再次出血；然而，大多数再次出血的是患有严重基础疾病的急性黏膜病变患者。5例患者接受了急诊手术，大多数患者在双极电凝成功止血后避免了手术。该操作未出现相关并发症。使用我们的电凝器进行双极电凝是一种安全且易于应用的技术，有望成为目前可用的内镜止血方法的补充。
