上消化道黏膜下肿瘤的内镜超声随访研究

Endoscopic ultrasonography follow-up in patients with upper gastrointestinal submucosal tumours

目的:观察上消化道黏膜下肿瘤(SMT)的动态变化. 方法:对32例初次EUS诊断为SMT的患者进行EUS随访观察. 结果:90.1%(29/32)复查EUS与初次诊断一致,间质瘤95.5% (21/22)与初次诊断相吻合.21例2次EUS均诊断为间质瘤的患者中,33.3%第2次EUS显示的生长方式有变化;47.6% 2次EUS显示的形态不同;57.1%(12/21)2次EUS大小有差异,其中第2次EUS较首次增大者占66.7%(8112),其直径在随访间期9 mo内平均增长3.5(2-7 mm). 结论:EUS诊断上消化道SMT的准确性很高,定期随访复查EUS,对尽早确诊SCT并判断其良恶性,选择合理治疗策略是必要的.

AIM: To observe the alteration of upper gastrointestinal submucosal tumor (SMT). METHODS: The first diagnostic SMT patients (n=32) were observed with endoscopic ultrasonography (EUS) and followed-up. RESULTS: The second and the first EUS findings coincided in 90.1% of cases (29/32), 95.5% (21/22) of the SCT diagnoses were identical to the first EUS. In 21 SCT cases, which diagnosed with EUS in both times, 33.3% showed the alteration of growth type in the second time, and 47.6% showed difference between both EUS-examinations; 57.1% (12/21) of the double EUS showed different tumor size, 66.7% (8/12) of which ones were greater than the first EUS. The diameter was increased 3.5 (2-7) mm in a 9-month follow-up term. CONCLUSION: EUS is very accurate for the diagnosis of upper gastrointestinal SMT, and long time follow-up with EUS is necessary to distinguish the benign from malignancy of SMT and to guide the therapeutic approach.
