在狗的胃或食管出血部位进行电凝治疗，使用电烧刀装置通过内窥镜（Cameron-Miller型号80-7910），使用柔性吸式凝固电极。对25只狗进行的急性和慢性凝血研究表明，在5级电灼单位设置下，电凝对食管和胃粘膜是安全的，持续3 - 5秒。通过取多个大的活检标本，这种水平的凝血可以成功地停止由食管和胃粘膜缺损出血引起的出血。根据这些资料，6例活动性胃出血病变患者进行了粘膜凝固治疗。这在所有6名患者中都成功地初步止住了出血；两名患者在48小时内复发并需要手术干预。进一步的临床评估正在实施，以确定其在治疗上消化道出血的临床作用。
Electrocoagulation of gastric or esophageal bleeding sites was evaluated in dogs using a flexible suction coagulator electrode passed through the endoscope using an electrocautery unit (Cameron-Miller model 80-7910). Acute and chronic coagulation studies in 25 dogs showed that electrocoagulation of both the esophageal and gastric mucosa was safe at an electrocautery unit setting of 5 for three to five seconds. This level of coagulation was successful in stopping bleeding created from actively bleeding esophageal and gastric mucosal defects by taking multiple large biopsy specimens. Based on these data, six patients with active bleeding gastric lesions have undergone mucosal coagulation. This successfully stopped the bleeding initially in all six patients; two patients rebled and required operative intervention within 48 hours. Further clinical evaluation is being implemented to determine its clinical role in the treatment of bleeding in the upper part of the gastrointestinal tract.
