目的探讨超声内镜在胃异位胰腺与间质瘤鉴别诊断中的价值.方法回顾分析经病理证实的40例胃异位胰腺与141例间质瘤患者的临床资料和超声检查结果,包括病变的部位、大小、起源层次、生长方式、内部回声等.结果胃异位胰腺最常位于胃窦部(92.5％),胃间质瘤多位于胃体(45.4％)、胃窦(23.4％)和胃底(22.0％),两者病变部位差异有统计学意义(P ＜0.001).胃异位胰腺与间质瘤在最长/最短直径比值方面差异无统计学意义(P=0.057).间质瘤与异位胰腺大小差异有统计学意义(19.98±12.80)mm对(11.25±3.61)mm,P＜0.001)].异位胰腺多起源于第3层(黏膜下层,75％),间质瘤常起源于第4层(固有肌层,54.6％)和第2层(黏膜肌层,34.0％),两者起源层次差异有统计学意义(P ＜0.001).异位胰腺以肌壁内生长为主(82.5％),间质瘤以肌壁内生长(37.6％)、腔外生长(24.8％)和腔内生长(22.7％)为主,两者生长方式差异有统计学意义(P ＜0.001).内部回声方面,异位胰腺以低回声(32.5％)、中等回声(27.5％)和混合回声(27.5％)为主,间质瘤多为均匀低回声(72.3％).结论超声内镜下异位胰腺与间质瘤在病变部位、大小、起源层次、生长方式和回声方式上差异有统计学意义,对胃异位胰腺和间质瘤的鉴别有重要价值.

Objective To explore the value of endoscopic ultrasound (EUS) in differential diagnosis of ectopic pancreas and stromal tumor in stomach.Methods The clinical data and endoscopic ultrasound findings of 40 patients with ectopic pancrea and 141 patients with stromal tumor were retrospectively analyzed,including the location,size,growth pattern,layer of origin,internal echo pattern and so on.All patients were diagnosed pathologically.Results Ectopic pancreas were predominantly located in the antrum (92.5％) and stromal tumor were mainly located in the gastric body (45.4％),the antrum (23.4％) and the fundus (22.0％),there was a significant difference in lesion' s location between two diseases (P ＜0.001).There was no statistical difference in the ratio of longest/shortest diameter of the lesion size(P =0.057).But there was statistical difference in lesion size between ectopic pancrease and stromal tumor [(19.98 ± 12.80)mm vs (11.25 ± 3.61)mm].Mural growth pattern was most common in ectopic pancrease (82.5％) and mural growth pattern (37.6％),extraluminal growth pattern (24.8％) and intraluminal growth pattern (22.7％) in stromal tumor (P ＜0.001).The third layer (75.0％) was predominant in ectopic pancrease while the fourth (54.6％) and the second layers (34.0％) in stromal tumor (P ＜0.001).With regard to internal echo pattern,hypoechoic (32.5％),intermediate (27.5％) and heterogeneous (27.5％) was predominant in ectopic pancrease and homogeneous hypoechoic lesion (72.3％) in the stromal tumor (P ＜ 0.001).Conclusions There were statistical differences between ectopic pancrease and stromal tumor in the location,size,layer of origin,growth pattern and internal echo pattern under EUS.EUS plays an important role in identification of ectopic pancrease and stromal tumor.
