Electrochemical Therapy for Late Stage Esophageal Cancer
Patients with Serious Obstruction XIN Yu-Ling
China-Japan Friendship Hospital, Beijing 100029, China

From March of 1992 to December of 1993 we treated 102 late stage esophageal cancer patients with serious obstruction by using tube electrode developed in China. Among the group, 70 cases belonged to primary late stage esophageal cancer obstruction and 32 cases belonged to postoperative anastomotic stricture. All the strictures belonged to III or IV obstruction and die stricture degree was 1-3 mm according to esophagoscopy and the measurement on the barium radiography of esophagus. The patient could only take liquid food or live on intravenous infusion. Because they hadn‘t been able to take food for a long time, their constitution was very poor and they couldn‘t accept surgical treatment, radiotherapy, or chemotherapy. ECT method is simple, safe, and effective. As there is little harm done and patients recover quickly, it is accepted willingly by the old weak patients.

Clinical Materials

Among the group, there were 67 cases male and 35 case female. They ranged in age from 41 to 50 years (37 cases), 51 to 60 years(42 cases), and 61 to 78 years(23 cases).

Lesion sites: There were 21 cases with lesion in upper esophagus, 38 in the middle and 11 in lower esophagus, among the 70 cases with primary esophageal cancer. here were 27 cases with lesion in upper esophagus and 5 cases in the middle, among 32 cases with anastomotic stricture.

Pathological type: All cases were squamous cell carcinoma. Fifty-nine cases belonged to stenotic type, 32 cases belonged to medullary type and 11 cases belonged to fungoid type.

Stricture degree: There were no cases with J0 or 110 stricture, 42 cases(4 1.2%) with 11I~, and 60 cases (58.8%) with IV° stricture. Among 70 cases with primary esophageal cancer, there were 32 cases (45.7%) belonged to 1V0 stricture and 38 cases (54.3%) belonged to III~. Among 32 cases with anastomotic stricture there were 28 cases (87.5%).with 1V0 stricture and only 4 cases (12.5%) with 1110 stricture. lt is obvious that W° siricture was dominant among postoperative anastigmatic stricture.
