目的观察窄带成像技术(NBI)内镜在胃良恶性溃疡中的诊断价值。方法对97例胃溃疡患者进行观察,评价图像的清晰度,溃疡轮廓、周边黏膜胃小凹及微血管形态。结果 97例胃溃疡中,良性61例,恶性36例。对溃疡轮廓、周边黏膜胃小凹及微血管的观察,NBI具有绝对优势,与病理学诊断符合率、敏感性及特异性(94.85%、91.67%、96.72%)显著高于常规内镜(84.54%、80.56%、86.89%),P<0.05。结论 NBI对胃溃疡的鉴别优于常规内镜,提高早期胃癌检出率具有重要意义。
Objective To observe the diagnostic value of narrow band imaging (NBI) endoscopy in benign and malignant gastric ulcer. Methods 97 cases of gastric ulcer patients were observed, evaluate the clarity of the image, the ulcer contour, the surrounding mucosal pits and microvascular morphology. Results 97 cases of gastric ulcer, 61 cases of benign and malignant 36 cases. NBI has an absolute advantage in the observation of ulcer contour, peripheral mucosa and microvessels, and the coincidence rate, sensitivity and specificity (94.85%, 91.67%, 96.72%) with pathological diagnosis were significantly higher than those with conventional endoscopy (84.54% , 80.56%, 86.89%), P <0.05. Conclusion The identification of gastric ulcer by NBI is superior to conventional endoscopy, and it is of great significance to improve the detection rate of early gastric cancer.
