目的分析胃黏膜下肿瘤的病因、病变部位及超声内镜特点。方法回顾性分析105例对经超声内镜及微创手术组织病理证实的胃黏膜下肿瘤患者的临床资料。结果 105例中胃间质瘤55例,脂肪瘤10例,异位胰腺33例,类癌、平滑肌瘤及错构瘤各2例,囊肿1例;病变位于胃窦45例,胃底38例,胃体21例,胃角1例;超声内镜提示病变位于固有肌层55例,黏膜下层45例,黏膜肌层5例。结论胃黏膜下肿瘤的以间质瘤、异位胰腺多见,病变位于胃窦多见,其次为胃底;多数病变起源于固有肌层,其次为黏膜下层;超声内镜检查对胃黏膜下肿瘤诊断有较大价值;微创手术是有效治疗方法。
Objective To analyze the etiology, lesion site and characteristics of endoscopic ultrasonography in gastric submucosal tumors. Methods The clinical data of 105 patients with gastric submucosal tumors proved by ultrasonography and minimally invasive surgery were retrospectively analyzed. Results 55 cases of 105 cases of gastric stromal tumors, lipoma in 10 cases, 33 cases of ectopic pancreas, carcinoid, leiomyoma and hamartoma in 2 cases, cysts in 1 case; pathological changes in 45 cases of gastric antrum, stomach 38 Cases, 21 cases of gastric body, 1 cases of gastric angle; ultrasound endoscopic findings lesions located in the musculature of 55 cases, 45 cases of submucosa, 5 cases of muscularis mucosa. Conclusions Gastric submucosal tumors are more common in stromal tumors and ectopic pancreas. The lesions are more common in the antrum, followed by the gastric fundus. The majority of lesions originate from the muscularis propria, followed by the submucosa. Ultrasound endoscopy examines gastric mucosa Tumor diagnosis has great value; minimally invasive surgery is an effective treatment.
