放大窄带成像对大肠侧向发育性肿瘤病理类型的预测价值

Predictive value of narrow band imaging-magnifying endoscopy in pathological types of laterally spreading tumor of large intestine

摘要:

摘要：目的 探讨大肠侧向发育性肿瘤（LST）在放大窄带成像（ME-NBI）下的腺管开口类型、毛细血管分型与病理类型的关系，评估ME-NBI对LST病理类型的预测价值，以更好地选择LST的治疗方案。方法 回顾性分析2015年1月－2018年1月郑州大学第二附属医院消化内镜中心检出的具有完整临床和病理资料且诊断为LST的病历，收集相关病历的发病部位、年龄、大小、内镜下形态、腺管开口类型、毛细血管分型和病理类型，并进行相关分析。结果 LST内镜下不同分型的患者年龄、性别、病变直径、病变部位和病理类型比较，差异均无统计学意义（P >0.05）。病理类型与腺管开口、毛细血管分型差异有统计学意义（P =0.000）。结论 ME-NBI能有效预测LST病理类型，以更好地选择LST的治疗方案，降低大肠癌的发病率。直肠部位及内镜下分型为结节混合型（LST-G-M）的LST易癌变，在肠镜检查时要特别注意直肠部位的病变及LST-G-M病变。

Abstract: Objective To investigate the types of glandular duct opening, capillary type and pathological type of LST under ME-NBI, and evaluate the predictive value of ME-NBI for the pathological type of LST, so as to choose the treatment scheme of LST better. Methods From January 2015 to January 2018, the cases diagnosed as LST were analyzed retrospectively. The location, age and size of the related cases were collected. Endoscopic morphology, type of glandular duct opening, capillary type, pathological type, and correlation analysis. Results There was no significant difference between endoscopic classification of lateral developmental tumor and age, diameter, sex, lesion location and pathological type (P < 0.05). There was significant difference between pathological type and opening of glandular duct and capillary type (P = 0.000). Conclusion ME-NBI can effectively predict the pathological types of LST, so as to choose the treatment of LST better and reduce the incidence of colorectal cancer. LST, classified as nodular mixed type under rectum and endoscopy, is prone to carcinogenesis, so we should pay special attention to rectal lesions and mixed nodular lesions during endoscopy.
