目的 研究内镜电化学对食管、贲门癌及其术后食管胃吻合口狭窄的治疗作用。 方法 对6例食管癌、6例贲门癌及4例食管贲门癌术后食管胃吻合口狭窄患者,在纤维内镜监视导引下对癌肿及吻合口狭窄局部行电化学治疗。 结果 治疗后,6例食管癌达CR 2例,PR 3例,NC 1例总有效率83％(5/6);6例贲门癌达CR 3例,PR 3例,总有效率100％(6/6);4例吻合口狭窄明显扩张,吞咽困难明显改善。 结论 本法能使癌组织坏死,吻合口狭窄扩张,解除食管腔的机械性梗阻,使患者能经口进食。
Objective To study the therapeutic effect of endoscopic electrochemistry on esophageal and cardiac cancer and postoperative esophageal anastomotic stenosis. Methods Esophagogastric anastomotic stenosis was performed on 6 patients with esophageal cancer, 6 patients with cardiac cancer, and 4 patients with esophageal and cardiac cancer. Electrochemical treatment of cancer and anastomotic stenosis was performed under fiberoptic endoscopic surveillance. Results After treatment, 6 cases of esophageal cancer had CR 2 cases, PR 3 cases, NC 1 case total effective rate 83% (5/6); 6 cases of cardiac cancer reached CR 3 cases, PR 3 cases, total effective rate 100% ( 6/6); 4 cases of anastomotic stenosis were significantly dilated and dysphagia was significantly improved. Conclusion This method can make the cancer tissue necrosis, anastomotic stenosis expansion, release the mechanical obstruction of the esophagus cavity, so that patients can eat by mouth.
