  • Significance of UltrasoundGuided Core Needle Biopsy in Diagnosis of Thyroid Nodules

    ObjectiveTo explore the value of ultrasound-guided core needle biopsy (CNB) in diagnosis of thyroid nodules. MethodsThe clinical data of 347 patients with thyroid nodules who underwent ultrasoundguided CNB were retrospectively analyzed, and the results of CNB pathology were compared with postoperative wax pathology results. ResultsAll patients completed CNB successfully and satisfaction rate for tissue samples was 100%. After CNB, local hematoma occurred in two cases and relieved by conservative therapy. The CNB pathology results of 347 cases of patients were as follows: 117 cases were malignancy, including papillary thyroid cancer in 115 cases, undifferentiated adenocarcinoma in 1 case, and squamous cell carcinoma in 1 case; 230 cases were benign, including thyroiditis in 53 cases, and nodular goiter in 141 cases, adenoma in 16 cases, and nodular goitre coexisting thyroiditis in 20 cases. In 132 cases of patients underwent surgery including 113 cases of malignancy and 19 cases of benign disease, the CNB pathology results in 127 cases were consistent with postoperative wax pathology results and false negative occurred in 5 cases. The diameter of thyroid nodules were not more than 0.5 cm in 4 cases, 0.5-1.0 cm in 59 cases, 1-2 cm in 46 cases, and more than 2 cm in 23 cases, and the accuracy rate of CNB pathology results was 75.0%(3/4), 98.3%(58/59), 97.8%(45/46), and 91.3%(21/23), respectively, which was the highest in 0.5-2.0 cm. The accuracy, sensibility, specificity, positive predictive value, negative predictive value, failure rate, and misdiagnosis rate of ultrasound-guided CNB for differential diagnosis of thyroid malignant nodules from benign nodules were 96.21% (127/132), 95.76% (113/118), 100% (14/14), 1 (113/113), 0.74 (14/19), 4.24%(5/118), and 0 (0/14), respectively. ConclusionUltrasound-guided CNB has important value on differential diagnosis of thyroid nodules, and important guiding significance on treatment of thyroid diseases.

  • 关节镜辅助下空心螺钉固定治疗新鲜腕舟骨骨折

    目的 探讨关节镜辅助下空心螺钉固定治疗新鲜腕舟骨骨折的疗效。方法 2022年5月—2023年2月,采用关节镜辅助下空心螺钉固定治疗30例腕舟骨骨折患者。男15例,女15例;年龄22~64岁,平均44.1岁。致伤原因:运动伤9例,交通事故伤9例,跌倒伤12例。骨折根据Herbert分型标准为B1型9例、B2型21例,均未合并三角纤维软骨复合体及韧带损伤。受伤至手术时间2~14 d,平均6.0 d。记录手术时间、术中出血量以及并发症发生情况。影像学复查骨折愈合情况,12个月时行改良Mayo腕关节评分及Herbert和Fisher腕舟骨骨折评价,测量腕关节主动屈、伸及桡偏、尺偏活动度并与健侧进行比较。结果 手术时间40~65 min,平均53.5 min;术中出血量5~20 mL,平均11.2 mL。患者均获随访,随访时间12~15个月,平均13.3个月。术后切口均Ⅰ期愈合,未出现感染、神经血管损伤等并发症。影像学复查示术后6个月时骨折均达骨性愈合,随访期间未出现螺钉松动等并发症。术后12个月,改良Mayo腕关节评分达优27例、良3例;Herbert和Fisher腕舟骨骨折评价达0级27例、1级3例;患侧腕关节主动屈、伸、桡偏、尺偏活动度均小于健侧,差异有统计学意义(P<0.05)。结论关节镜辅助下空心螺钉固定具有微创、精确复位及快速康复的优势,是治疗新鲜腕舟骨骨折有效方法。
