目的
2
探讨不同探头超声内镜(EUS)对消化道黏膜下肿瘤(SMT)直径测值的影响。
方法
2
回顾性分析2023年1月至2024年6月在陆军军医大学第二附属医院经EUS检查初步诊断为SMT的356例患者(共372个病变)的临床资料。分析SMT起源层次基本特征及病理分布情况。比较不同病变直径范围EUS下SMT直径测值与实际直径的差异。以术后病理诊断结果为金标准,分析不同临床病理特征及探头类型对EUS下SMT直径测值相对误差的影响。
结果
2
372个消化道SMT中女性
患者病变较多,以胃部最多见;病理类型以平滑肌瘤为主。EUS诊断SMT的准确率为94.4%。SMT的EUS直径测值与实际直径比较,差异具有统计学意义(
P
<
0.05)。EUS直径测值在不同病变直径范围内与实际直径比较,差异均有统计学意义(
P
<
0.05)。性别、年龄、病变部位、病理类型对EUS下直径测值的相对误差无显著影响(
P
>
0.05);探头类型对EUS下直径测值的相对误差有显著影响(
P
<
0.05)。在实际直径为2.0~3.9 cm的病变中,小探头EUS测量SMT直径的相对误差明显大于大探头EUS(
P
<
0.05)。
结论
2
大探头EUS对直径≥2.0 cm的SMT直径测值相对误差较小,故对于预估直径在2.0 cm以上的SMT建议选择大探头EUS进行检查。
Objective
2
To explore the effect of endoscopic ultrasonography (EUS) with different probes on the measurement of gastrointestinal submucosal tumor (SMT) diameter.
Methods
2
The clinical data of 356 patients (with a total of 372 lesions)initially diagnosed as SMT by EUS at the Second Affiliated Hospital of Army Medical University from January 2023 to June 2024 were analyzed retrospectively. The basic characteristics of the origin layers and pathological distribution of SMT were analyzed. The differences between the EUS-measured diameters and the actual diameters of SMT at different diameter ranges of lesions were compared. Taking the postoperative pathological diagnosis results as the gold standard, the effects of different clinicopathological features and probe types on the relative error in EUS-measured diameters of SMT were analyzed.
Results
2
Among the 372 gastrointestinal SMT lesions,lesions were more frequent in female patients, gastric lesions was the most common, and leiomyoma was the predominant pathological type. The accuracy of EUS in diagnosing SMT was 94.4%. A statistically significant difference was observed between the EUS-measured diameters and the actual diameters of SMT (
P
<
0.05). There were significantly differences in various ranges of lesions between the EUS-measured diameters and the actual diameters(
P
<
0.05). The gender, age, lesion location, and pat
hological type had no significant effect on the relative error of EUS-measured diameters (
P
>
0.05);while probe types had a significant effect on the relative error of EUS-measured diameters(
P
<
0.05). For lesions with an actual diameter of 2.0 to 3.9 cm, the relative error of SMT diameters measured by small-probe EUS was significantly greater than that by large-probe EUS (
P
<
0.05).
Conclusion
2
Large-probe EUS exhibits a smaller relative error in measuring the diameter of SMT with a diameter of ≥2.0 cm. Therefore, large-probe EUS is recommended for the examination of SMT with an estimated diameter exceeding 2.0 cm.
