目的探讨经内镜进行食管黏膜碘染色方法对大连地区原居民早期食管癌的发现价值。方法对45岁以上有上消化道症状的病人行胃镜检查时进行卢戈氏碘液的喷洒,对不染区进行多点病理活检。结果有食管病变病人异常发现率为73.85%,癌前病变发生率为35.38%,早期食管癌发生率为1.54%。结论具有明显食管症状、内镜下发现食管黏膜可疑病变的病人,尽可能要进行碘染色和精确活检。对发现癌前病变的病人,要及时随访,反复碘染检查。大连地区原居民早期食管癌的发生率并不比全国发病率低。
Objective To explore the value of endoscopic esophageal mucosal iodine staining of early esophageal cancer in Dalian residents. Methods Patients with upper gastrointestinal symptoms over the age of 45 underwent gastroscopy Lugol’s iodine solution was sprayed on the stained area for multi-pathological biopsy. Results The prevalence of esophageal lesions was 73.85%, the incidence of precancerous lesions was 35.38%, and the incidence of early esophageal cancer was 1.54%. Conclusions Patients with obvious esophageal symptoms and suspicious lesions of esophageal mucosa detected by endoscopy should carry out iodine staining and biopsy accurately. On the discovery of precancerous lesions of patients, timely follow-up, repeated iodine staining. The incidence of early esophageal cancer among indigenous residents in Dalian is no lower than the national incidence.
