经硬质食管镜和手术中,用特制的微波辐射器对具有严重吞咽困难的晚期食管及贲门癌性梗阻作微波组织凝固治疗.本组31例,均为仅能进流质甚或滴水不入的晚期病人。全组病人经一次性治疗后都能恢复半流质饮食或者无渣普食,未发生微波组织凝固引起的消化道穿孔或出血等并发症。由于能经口进食,病人的全身情况明显改善。经随访,病人进食改善期为1.5～14个月,平均6.4月。 After rigid esophagoscopy and surgery, a special microwave irradiator was used to treat patients with advanced esophageal and cardia cancer obstruction with severe dysphagia by microwave coagulation therapy. In this group, 31 cases were invasive or even inaccessible. Late-stage patient. After one-time treatment, the patients in the whole group were able to recover a semi-liquid diet or without food, and no complications such as perforation of the digestive tract or hemorrhage caused by microwave tissue coagulation occurred. As a result of oral feeding, the patient’s general condition improved significantly. After follow-up, the patient’s eating improvement period was 1.5 to 14 months with an average of 6.4 months.
