| 目的 探讨超声检查对小儿结肠息肉的诊断价值。 方法 回顾性分析接受常规超声或结合生理盐水灌肠后超声检查的结肠息肉患儿46例,以结肠镜检查为金标准,对超声检出结肠息肉的敏感度进行统计学分析。 结果 结肠镜诊断结肠息肉患儿46例,其中单发息肉44例,2枚息肉2例;7枚息肉直径≤1 cm,38枚>1 cm且<3 cm者,3枚≥3 cm。超声诊断息肉患儿43例,其中单发息肉42例,2枚息肉1例;超声漏诊3例(4枚息肉)。超声检出息肉的总敏感度为91.67%(44/48),其中对直径>1 cm且<3 cm、≥3 cm息肉的敏感度分别为97.37%(37/38)、100%(3/3),明显高于直径≤1 cm的结肠息肉检出敏感度(4/7,57.14%)。 结论 超声检查具有安全、无创、简便等特点,可作为检查小儿结肠息肉的首选方法。 |

| Objective To explore the diagnostic value of ultrasonography in children with colonic polyps. Methods Conventional and (or) saline enema ultrasound examination were performed in 46 children with colonic polyps. Taking colonoscopic findings as the gold standard, the sensitivity of ultrasonography in detecting colonic polyps was analyzed statistically. Results Forty-six children were diagnosed as colonic polyps with colonoscopy, including single polyp in 44 cases, 2 polyps in 2 cases. Seven polyps were ≤1 cm, 38 polyps were >1 cm and <3 cm, while 3 polyps were ≥3 cm. Forty-three children were diagnosed as colonic polyps with ultrasonography, including single polyp in 42, 2 polyps in 1 case. Ultrasonography missed 3 cases and 4 polyps. The sensitivity of ultrasonography in detecting colonic polyps was 91.67% (44/48) of all, 97.37% (37/38) of polyps >1 cm and <3 cm, and 100% (3/3) of polyps ≥3 cm, but only 57.14% (4/7) of polyps ≤1 cm. Conclusion Ultrasonography is safe and simple, which may be used as the preferred method to diagnose colonic polyps in children. |
