摘要
目的探讨数字化成像对早期食管癌的诊断价值。方法83例经手术病理证实早期食管癌根据X线检查机型分为数字化X线摄影组(DR组,48例)和普通X线摄影组(对照组,35例),所有患者均作多相钡剂造影,以大口服钡法为主,并摄电子点片及选择性激光输出,X线片摄常规正侧位及左、右前斜位片,电子点片多体位摄取。结果DR组48例中术前发现早期食管癌45例,漏诊3例,诊断准确率为93.3%;对照组35例中术前发现早期食管癌29例,漏诊6例。两组检出率行统计学分析,P<0.01,差异有显著性统计学意义。结论数字化X线机的应用能显著提高早期食管癌的检出率,但胃镜及细胞学检查仍是其必要的补充。
Objective To study the diagnostic value of digital radiography（DR）for early esophageal carcinoma. Methods Eightythree patients with surgically and pathologically proved early esophageal carcinoma were divided into two groups according to applied X - ray machines： DR group （ n = 48）underwent digital radiography and control group （ n = 35 ）underwent conventional radiography. All patients underwent barium meal examinations before operation. Results Among 48 cases of DR group, 45 cases were definitely diagnosed while only 3 cases were leaking - diagnosed, the diagnostic accuracy was 93.7 %. Among 35 cases of control group, 29 cases were definitely diagnosed and 6 cases were leaking - diagnosed, the diagnostic accuracy was 82. 8 %. The statistic analysis shown that, there was significant difference between the both groups （ p 〈 0.01 ）. ConclusionThe application of DR can greatly increase the detection rate of early esophageal carcinoma but the gastroscopy and pathological biopsy still are imoportant supplement means.
