目的总结超声胃镜判定胃肿瘤性质失误的原因。方法回顾性分析2010年7月—2012年5月术前超声胃镜判定胃肿瘤性质失误18例的表现及病理特点。结果本组由超声胃镜诊断胃肠道间质瘤(GIST)55例均行手术切除,术后病理证实为胃间质瘤37例,18例误诊,误诊率32.73%。18例病理确诊为胃平滑肌瘤8例,胃神经鞘瘤3例,胃异位胰腺3例,胃血管畸形2例,胃结节性纤维性假瘤1例,胃重复畸形1例。结论超声胃镜在GIST诊断方面没有特异性,误诊率偏高,可以同时行电子胃镜检查,以弥补超声胃镜的不足。超声胃镜引导多部位细针穿刺抽吸术可以术前确诊GIST,降低超声胃镜的误诊率。
Objective To summarize the causes of errors of gastroscopy in determining gastric tumor. Methods Retrospective analysis of the performance and pathological features of 18 patients with gastric tumor diagnosed by gastroscopy from July 2010 to May 2012 were retrospectively analyzed. Results All 55 cases of gastrointestinal stromal tumors (GIST) were diagnosed by gastroscopy in this study. 37 cases were diagnosed as gastric stromal tumors by pathology and 18 cases were misdiagnosed with misdiagnosis rate of 32.73%. Pathological diagnosis of 18 cases of gastric leiomyoma in 8 cases, gastric schwannoma in 3 cases, gastric heterotopic pancreas in 3 cases, 2 cases of gastric vascular malformations, 1 cases of gastric nodular fibrosis, 1 case of gastric deformity. Conclusion Ultrasound gastroscopy is not specific in the diagnosis of GIST, the misdiagnosis rate is high, you can simultaneously electronic gastroscopy to make up for the lack of endoscopy. Ultrasound gastroscopy guided multi-site fine needle aspiration surgery can be diagnosed before GIST, to reduce the misdiagnosis rate of endoscopic ultrasonography.
