Background: Papillary thyroid carcinoma is the most common thyroid carcinoma. There is a debate on prophylactic removal of central lymph nodes. Some authors advise it to avoid recurrence while other investigators condemn it due to its higher risk of recurrent laryngeal nerve injury and/or hypoparathyroidism. Aim of the Work: The aim of this study was to evaluate the safety and morbidity of central lymph nodes dissection during total thyroidectomy in the management of patients with papillary thyroid carcinoma. Patients and Methods: Twelve patients were confirmed by histopathological evaluation to have papillary thyroid examination. Total thyroidectomy was done through transverse neck incision followed by removal of bilateral central group of lymph nodes. Patients were examined postoperatively for recurrent laryngeal nerve injury or hypoparathyroidism. Follow up was done 6 months later with neck ultrasonography, thyroglobulin and antithyroglobulin antibodies. Results: Thirty four percent of the studied cases proved to have lymph nodes metastasis. temporary hypocalcemia occurred in only one patient in this study and was temporary. Recurrent laryngeal nerve affection happened in 17% of the studied cases and was reversible by medical treatment. No evidence of recurrence happened in the first 6 months after operation. Conclusion: The risk of postoperative recurrent laryngeal nerve injury or hypoparathyroidism is minimal after prophylactic CLND. Postoperative hypocalcemia and recurrent laryngeal nerve injury are usually reversible.

ObjectiveTo evaluate the diagnostic performance of preoperative contrast-enhanced ultrasound (CEUS) in the detection of extracapsular extension (ECE) and cervical lymph node metastasis (LNM) of papillary thyroid carcinoma (PTC) and the added value of CEUS in the evaluation of PTC invasiveness to conventional ultrasound (US).Materials and MethodsA total of 62 patients were enrolled retrospectively, including 30 patients with invasive PTCs (Group A, ECE or LNM present) and 32 patients with non-invasive PTCs (Group B). All patients underwent US and CEUS examinations before surgery. US and CEUS features of PTCs and lymph nodes were compared between groups. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of US, CEUS, and the combination of the two in the detection of ECE and LNM of PTCs were calculated. Logistic regression was used to analyze relationships between variables.ResultsThe PTC size was larger in group A on both US and CEUS (P = 0.001, P = 0.003). More PTCs showed hyper-enhancement in group A (P = 0.013) than in group B. More PTCs had >25% contact between PTC and the thyroid capsule and discontinued capsule on US and CEUS (all P < 0.05) in group A than in group B. More absent hilum and calcification of lymph nodes were observed in group A (both P < 0.05) than in group B on US. More centripetal perfusion and enlarged lymph nodes were observed in group A (both P < 0.05) than in group B on CEUS. CEUS alone and US combined with CEUS manifested higher diagnostic accuracy (79.0%) than US alone (72.6%) in the detection of ECE. The combination of US and CEUS manifested the highest diagnostic accuracy (95.2%) than CEUS alone (90.3%) and US alone (82.2%) in the detection of LNM. Diagnoses of ECE and LNM by the combination of US and CEUS were independent risk factors for PTC invasiveness [odds ratio (OR) = 29.49 and 97.20, respectively; both P = 0.001].ConclusionCEUS or US combined with CEUS is recommended for the detection of PTC ECE, while the combination of US and CEUS is most recommended for LNM detection. CEUS plays an essential role in the preoperative evaluation of PTC invasiveness.
