摘要
我们从1985至1987年对71例食管贲门疾病在纤维食管镜下用0.3%美兰进行染色和对18例切除标本用0.1%美兰进行染色。结果食管镜下染色71例中,恶性病变染色率100%,诊断率98.2%;良性病变染色率6.2%(1/16)。切除标本染色18例中染色率和诊断率均为100%。本法能提高癌的诊断率;能够发现早期微小癌和癌的卫星灶。对临床确定病变的部位和范围,指导手术切除范围和鉴别良性恶性病变均有较大的帮助。
Staining of 71 cases of esophageal and cardiac lesions with 0.3% methylene blue sprayed to the mucosa during the esophagoscopy and 18 cases of resection specimens of esophageal and cardiac carcinoma with 0.1% methylene blue were made during 1985 to 1987. In 71 cases stained under the e- sophagoscopy,staining rate in malignant lesions is 100%, diagnosis rate 98.2%; in benign lesions,staining rate is only 6.2%.In 18 resection specimens both staining and diagnosis rate are 100%.The increase rate is made in diagnosis of the carcinoma and small mucosal carcinoma as well as satellite carcinoma adjacent to the main carcinoma are identified with this method. It is also helpful with this method in confirming the site and extent of the carcinoma so as to direct the surgical resection, and in differentiation of benign and malignant lesions.
