This prospective non-randomised trial of 128 selected patients with unresectable oesophageal or gastrooesophageal junction cancers aims to evaluate the initial relief of malignant obstruction by means of bipolar electrocoagulation for both circumferential and submucosal strictures of Nd:YAG laser for the other patients. A limited dilatation was performed initially if a small calibre endoscope was unable to pass through the stricture. Prompt and significant relief of dysphagia without complications was achieved in 83% of patients. Improved patients were retreated monthly during the follow up period. Radiotherapy was recommended when possible. Symptomatic relief of obstruction lasted 4.2 months on average and 76% of patients remained palliated until death. Monthly retreatment using the most appropriate endoscopic procedure for the tumour configuration and radiotherapy after endoscopic relief of obstruction seems to give the best palliation for patients with unresectable cancers of the oesophagus or gastrooesophageal junction.
这项针对128例经挑选的不可切除食管癌或食管胃交界癌患者的前瞻性非随机试验,旨在评估通过双极电凝术对恶性梗阻进行初始缓解,以处理环形狭窄,而对于其他患者则采用钕钇铝石榴石激光进行黏膜下狭窄处理。如果小口径内镜无法通过狭窄部位,则最初进行有限扩张。83%的患者实现了吞咽困难迅速且显著缓解且无并发症。病情改善的患者在随访期间每月接受再次治疗。尽可能推荐放疗。梗阻症状缓解平均持续4.2个月,76%的患者直至死亡仍保持姑息状态。对于食管或食管胃交界不可切除癌患者,根据肿瘤形态采用最合适的内镜手术每月进行再次治疗,并在内镜缓解梗阻后进行放疗,似乎能提供最佳姑息治疗效果。
