ObjectiveTo summarize the efficacy and safety of Jindan Fuyan Granule in the treatment of refractory chylous leakage after neck lymph node dissection for thyroid cancer. MethodThe clinical data of thyroid cancer patients with refractory chylous leakage after neck lymph node dissection treated with Jindan Fuyan Granules in the Department of Head and Neck Surgery of Jiangsu Cancer Hospital from January to December 2023, were retrospectively collected. ResultsAfter treatment with Jindan Fuyan Granules on the basis of conventional treatment, the drainage volume of 3 patients with thyroid cancer after radical neck lymph node dissection was significantly reduced, from 100 mL to 2 mL, 1 285 mL to 5 mL, and 960 mL to 5 mL, respectively. After 3 days of treatment, the tubes were removed successfully. After discharge from the hospital, 3 patients were followed up for 3, 3, 4 months, respectively, showing satisfactory wound healing without chylous leakage or other discomfort. ConclusionsCombined with low-fat diet, drainage and other non-surgical treatment methods, Jindan Fuyan Granule has obvious effect on treating refractory chylous fistula after neck lymph node dissection, which can be used as a non-surgical treatment option. However, the efficacy needs to be further verified.
ObjectiveTo summarize the new ideas and new instruments in thyroid surgery. MethodsRelated literatures were reviewed and analyzed. ResultsTotal thyroidectomy had become the preferred option for differentiated thyroid cancer and multiple nodule goiter. The key change of surgery was from recurrent laryngeal nerve-protection to parathyroid-protection. Harmonic scalpel, bipolar coagulation forceps and Ligasure were used to thyroid surgery, which could shorten operation time and reduce operative bleeding. ConclusionThe ideas and techniques of thyroid surgery have changed, total thyroidectomy and parathyroid protection are being paid more and more attentions, and new instruments are used more extensively in thyroid surgery.
颈淋巴结清扫术后乳糜漏是颈部外科手术后比较少见的并发症，国内、外文献［1-7］报道其发生率约为1%～3%，其原因很明确，即术中损伤胸导管或其分支。颈淋巴结清扫术后乳糜漏对生命有潜在威胁，且显著延长患者住院时间、增加医疗费用。尽管手术方法及手术器械不断改进，其发生率并没有明显降低，对于部分难治性乳糜漏目前还没有简单有效的办法。现就颈淋巴结清扫术后乳糜漏的预防及治疗方法介绍如下……
ObjectiveTo analyze the relevant factors of levelⅡlymph node metastasis in papillary thyroid carci-noma. MethodsThe clinicopathologic data of 83 patients from November 2011 to March 2014 were analyzed retrospec-tively. All the primary tumors were papillary thyroid carcinoma located in unilateral lobe with ipsilateral lateral neck lymph node metastasis. The relationship of gender, age, microcarcinoma, superior pole involved by carcinoma, integrated tumor capsule, or extranodal invasion to levelⅡlymph node metastasis was analyzed. The calculated data were analyzed with Chi-Square test and there was significant difference when P < 0.05. ResultsThe rate of lymph node metastasis at levelⅡ, Ⅲ, Ⅳ, Ⅴ, Ⅵwas 51.8% (43/83), 78.3% (65/83), 71.7% (59/83), 4.8% (4/56), and 79.5% (66/83), respectively. There was no significant relationship of gender, age, microcarcinoma, integrated tumor capsule, or extranodal invasion to levelⅡlymph node metastasis (P > 0.05). The rate of lymph node metastasis at levelⅡwas significantly higher when superior pole involved by carcinoma (P < 0.05). ConclusionAmong the patients with papillary thyroid carcinoma, when superior pole involved by carcinoma the patient should be underwent selective neck dissection, the proper extent of dissection including levelⅡshould be performed.
ObjectiveTo investigate the cause and treatment for chyle fistula after neck radical dissection using harmonic scalpel. MethodsFrom January 2005 to April 2009, 105 patients with thyroid carcinoma underwent thyroidectomy by harmonic scalpel (harmonic scalpel group) and 110 patients with thyroid carcinoma by conventional procedures (conventional group). Postoperative chyle fistula in all the cases was studied retrospectively. ResultsThe incidence of chyle fistula was 5.71% (6 of 105 patients) in the harmonic scalpel group and 0.91% (1 of 110 patients) in the conventional group. The difference was significant between two groups (Plt;0.05). ConclusionsHarmonic scalpel increases the risk of chyle fistula in neck radical dissection. The conventional procedures with exposing and preserving or ligating the thoracic duct can reduce the risk significantly.
ObjectiveTo investigate the risk factors for neck lymph node metastasis (LNM) in papillary thyroid microcarcinoma, analyze the diagnostic value of high resolution ultrasonography in lateral neck LNM, and evaluate the safety of lymph node dissection. MethodsThe clinical data of 284 patients with papillary thyroid microcarcinoma from Janaury 2004 to June 2010 in this hospital were analyzed retrospectively. ResultsNeck LNMs were found in 83 of 284 patients (29.2%), only central LNMs in 63 of 284 patients (22.2%), skip LNMs (only lateral LNMs) in 6 of 284 patients (2.1%), and both central and lateral LNMs in 14 of 284 patients (4.9%). Age lt;45 years, multifocality, tumor diameter ≥5 mm, and extrathyroidal invasion were the risk factors for LNM (Plt;0.05), and no risk factor for skip LNM was found. Patients underwent central and lateral lymph node dissection had longer postoperative hospital stay than those without dissection or with central lymph node dissection only (Plt;0.05). Both parathyroid gland and recurrent laryngeal nerve injuries were temporary postoperatively. There were no differences in injury rate among three methods (Pgt;0.05). The sensitivity, specificity, false negative rate, and false positive rate of high resolution ultrasonography for only lateral neck LNM were 95.0%, 75.0%, 5.0%, and 25.0%, repectively. The positive predictive value and negative predictive value were 90.5% and 85.7%, respectively. ConclusionsTotal thyroidectomy should be performed in patients with risk factors for LNM, and simultaneous central lymph node dissection is safe. High resolution ultrasonography is of great value in diagnosing skip LNM, and functional lymph node dissection also should be applied in patients who are highly suspected to have skip LNM.
ObjectiveTo study the regularity of cervical lymph node metastasis in papillary thyroid carcinoma and a reasonable surgical method. MethodsThe clinical data of 221 cases of papillary thyroid carcinoma treated in this hospital between September 2004 and September 2009 were analyzed retrospectively. ResultsThere were 32 cases treated with total thyroidectomy, 189 patients with subtotal thyroidectomy. Two hundred and two patients with unilateral thyroid carcinoma and 19 patients with bilateral thyroid carcinoma were diagnosed by pathology. The diameter of tumor was 0.2-8.0 cm with an average of 3.5 cm. The amicula invasion was found in 50 cases and mulifocality in 33 cases. The numbers of lymph node dissection were 10-24 with an average of 14.3 in unilateral. The total lymph node metastasis rate was 37.56% (83/221), the lymph node metastasis rate was 33.94% (75/221) in the Ⅵ region, and which was 18.10% (40/221) in the Ⅱ+Ⅲ+Ⅳ region. The rate of cervical lymph node metastasis markedly increased in the patients with the primary tumor diameter gt;1.0 cm, amicula invasion, multifocality, or age gt;45 years in the Ⅵ region and ipsilateral of Ⅱ+Ⅲ+Ⅳ region (Plt;0.05). ConclusionsIn patients with thyroid papillary carcinoma, the most common lymph node metastasis happened in the Ⅵ region, next in the Ⅱ+Ⅲ+Ⅳ region. Lymph nodes of the Ⅵ region should routinely be dissected in the first surgery, the lymph nodes of the Ⅱ+Ⅲ+Ⅳ region should be dissected when the tumor diameter gt;1.0 cm, amicula invasion, multifocality or ultrasonic, CT, and other imaging examinations demonstrated cervical lymph node metastasis.
