摘　　要：目的探讨经凸阵式超声胃镜引导细针穿刺(EUS-FNA)获取足量上消化道肌源性肿瘤病理标本的改进方法。方法选择直径在10 mm以上的上消化道肌源性肿瘤46例,以每组病例肿瘤直径相差小于2 mm为前提,随机分成对照组和实验组,对照组采用传统的提插式穿刺方式获取病理标本,试验组采用改进的提插加切割式穿刺方式获取病理标本,完成后对两组病例数据进行χ2检验。结果对照组有47.83%的病例获得足量病理标本,实验组有86.96%的病例获得足量病理标本,两组相比P<0.05。结论应用凸阵式超声胃镜引导细针穿刺时,采用改进的提插加切割式穿刺方法,获得足够病理标本的可能性高于传统的提插式穿刺方法。Objective To investigate the improved method to obtain enough pathological sample of myogenic tumor by curved linear array Endoscopic ultrasonograpby guided fine needle aspiration. Methods The group was composed of 46 eases with upper gastrointestinal myogenic tumor whose diameter was more than 10 millimeters. The difference of tumor diameter in each group was less 2 millimeter, and they are random divided into trial guoup and control group. The samples were obtained by traditional lift-insert puncture in control group while the ones in trial group were done accompanied with incision. X^2 test was taken in the two group. Resuits We could get enough samples in 47 . 83 % cases of control group and 86.96% in trial one , P〈0.05. Conclusion The possibility of enough samples by lift-insert puncture accompanied with incision was higher than the traditional method, when Endoscopic ultrasonography（EUS） was utilized.
