【摘要】：目的了解超声内镜下2cm、符合间质瘤影像学特点病变的随访情况,以选择合理随访时间。方法回顾性分析超声内镜下诊断2cm胃间质瘤患者,记录病变的部位、形态、大小、边界、内部回声等特征。并经超声内镜随访至少1次,比较病变大小及内部回声等变化情况。结果共66例病例纳入研究,根据随访时间记录,随访半年20例,随访1年29例,随访2年26例,随访3年18例,随访4年9例,随访5年4例,其中24例患者随访1次。观察超声内镜下病变大小,2年随访患者内镜下病变面积40mm2,初始内镜下病变面积38mm2,病变面积有增大趋势,两者比较有显著性差异(P=0.0240.05)。病变位于胃底占78.8%(52/66),来源于固有肌层占95.5%(63/66),所有病例未见回声异常改变及恶变表现。结论 2cm胃间质瘤好发于胃底,主要来源于固有肌层,超声内镜对2cm胃间质瘤定期随访安全,有效,对于1.5cm的胃间质瘤,建议可每2年复查一次。
[Abstract]:Objective to investigate the imaging features of stromal tumors (IST) under endoscopic ultrasonography (2cm) in order to select a reasonable follow-up time. Methods the location, shape, size, boundary and internal echo of 2cm gastric stromal tumors (GIST) diagnosed by endoscopic ultrasonography were analyzed retrospectively. Ultrasound endoscopy was followed up at least once to compare the changes of lesion size and internal echo. Results A total of 66 cases were included in the study. According to the records of follow-up, 20 cases were followed up for half a year, 29 cases for 1 year, 26 cases for 2 years, 18 cases for 3 years, 9 cases for 4 years and 4 cases for 5 years, among which 24 cases were followed up once. After 2 years follow-up, the lesion area was 40 mm 2 and 38 mm 2 respectively, and the lesion area increased with a significant difference (P < 0. 024 0. 05). The lesions were located in the fundus of the stomach in 78.8% (52 / 66) and from the muscular lamina propria in 95.5% (63 / 66). No abnormal echo or malignant changes were found in all cases. Conclusion 2cm gastric stromal tumors mainly originate from the lamina propria muscularis. EUS endoscopy is safe and effective for 2cm gastric stromal tumors. It is recommended that the gastric stromal tumors of 1.5cm should be reviewed every 2 years.
