目的:探讨色素胃镜诊断早期胃癌的价值。方法:行胃镜检查发现可疑胃黏膜异常1 154例,依据患者就诊时间分为研究组536例,对照组618例,研究组先应用亚甲蓝及刚果红染色再取活检送病理检查,对照组直接取活检送病理检查,比较2组早期胃癌检出率。结果:研究组检出早期胃癌29例(5.41%),对照组18例(2.91%),2组比较差异有统计学意义(χ2=4.584,P=0.032)。结论:色素胃镜可增强早期胃癌病灶的清晰度,增加活检阳性率,提高早期胃癌诊断率。
Objective: To explore the value of pigmented endoscopy in the diagnosis of early gastric cancer. Methods: According to gastroscopy, 1 154 cases of suspicious gastric mucosal abnormalities were found. According to the time of visiting the patients, 536 cases were divided into study group and 618 cases in control group. The study group was first biopsied with methylene blue and Congo red staining and the control group Take direct biopsy to send pathological examination, compared with the detection rate of 2 groups of early gastric cancer. Results: The study group detected 29 cases of early gastric cancer (5.41%) and 18 cases (2.91%) of the control group. The difference between the two groups was statistically significant (χ2 = 4.584, P = 0.032). Conclusion: Pigmented gastroscope can enhance the clarity of early gastric cancer lesions, increase the positive rate of biopsy and improve the diagnosis rate of early gastric cancer.
