本文就经内镜微超声探头(TEMP)诊断胃粘膜下肿瘤的价值,与胃镜和超声内镜作了比较研究。结果:①18例胃粘膜下肿瘤以粘膜下平滑肌瘤居多,占88.9％,以壁内型为主;②TEMP对肿瘤大小的判断符合率为88.9％,明显高于胃镜(33.3％),③TEMP对胃粘膜下肿瘤的总诊断符合率达100％,明显高于胃镜(61.l％),④胃粘膜下肿瘤的TEMP声像图特征与肿瘤的性质有关,其共同点为:肿瘤均为高回声粘膜带下的低回声病灶,病灶起源处有清晰的喇叭口,多呈圆形成类圆形,多向胃腔内隆起。结论:选择性应用TEMP诊断胃粘膜下肿瘤,尤其是小病灶和EUS难检病灶具有较大的价值。
In this paper, the value of endoscopic micro-ultrasound probe (TEMP) in the diagnosis of gastric submucosal tumors was compared with gastroscopy and endoscopic ultrasonography. RESULTS: Among the 118 cases of submucous tumors, submucosal smooth muscle tumors were mostly present, accounting for 88.9%, mainly in the form of in-wall; the judgment rate of 2TEMP for tumor size was 88.9%, which was significantly higher than that of gastroscopy (33.3%). The total diagnostic rate of gastric submucosal tumors was 100%, which was significantly higher than that of gastroscopy (61.1%). 4 The TEMP sonographic characteristics of gastric submucosal tumors were related to the nature of tumors. The common point was that tumors were high. Echo-submucosal hypoechoic lesions, where the lesions originated from a clear trumpet, were mostly circular in shape, and bulged more toward the stomach cavity. Conclusion: The selective use of TEMP for the diagnosis of gastric submucosal tumors, especially small lesions and EUS difficult to detect lesions is of great value.
