目的：观察食管腔内电极电化学治疗食管癌和贲门癌术后吻合口狭窄的效果。方法：应用特制的管式食管电极，采用电化学疗法治疗食管癌或贲门癌切除术后并发吻合口狭窄３１例，其中颈部吻合者３例、主动脉弓上者１１例、弓下者例１７例。吻合口宽度平均为０２８ｃｍ，仅能进全流食或不能进食水。依进食改善情况，酌情给予１次～４次治疗。结果：本组治疗后１９例（６１３％）患者可进普食或较固体食，９例（２９０％）进半流食，吻合口平均直径增加到１０ｍｍ。疗效维持＞０５ａ者为８０％，部分患者复发后再行电化学治疗，仍取得良好的效果。本组病例除少数在治疗中有短暂的胸骨后不适感外，无严重并发症发生。结论：本方法是一种简便、易行、安全的疗法，可明显改善患者的进食梗阻，提高患者的生存质量。
OBJECTIVE: To observe the effect of esophageal intraluminal electrodes for the treatment of anastomotic stenosis after esophageal and cardiac cancer surgery. METHODS: Thirty-one patients with anastomotic stoma stenosis after esophageal or cardiac cancer resection were treated with special tube-type esophageal electrodes. Among them, there were 3 cervical anastomoses, 11 aortic arch and 17 lower archers. . The average width of the anastomotic stoma is 028cm, and it can only enter into full flow or can not feed water. According to eating improvement, 1 to 4 treatments are given as appropriate. RESULTS: After treatment, 19 patients (61. 3%) could enter normal food or solid food, and 9 patients (29.0%) entered semi-liquid food. The average diameter of the anastomoses increased to 1 0 mm. The efficacy of maintaining >05a was 80%. Some patients relapsed and then performed electrochemical therapy, and still achieved good results. In this group of patients, except for a short period of poststernal discomfort during treatment, no serious complications occurred. Conclusion: This method is a simple, easy, safe therapy that can significantly improve the patient’s eating obstruction and improve the patient’s quality of life.
