Objective To explore the feasibility and safety of endoscopic thyroidectomy via chest-breast approachand summarize the operation skill. Method The clinical data of 40 cases performed endoscopic thyroidectomy via chest-breast approach from August 2010 to August 2012 in this hospital were analyzed retrospectively. Results The endoscopic thyroidectomies via chest-breast approach were successfully performed in all 40 patients without conversion to open surgery， massive haemorrhage， hypercapnia， severe subcutaneous emphysema， cutaneous necrosis on chest，permanent impairment of recurrent laryngeal nerve， and permanent hypoparathyroidism. One case of hoarseness was found on 2d after operation， who returned to normal after symptomatic treatment. One case of numbness in the extremitieshappened on day 2 after operation and the symptom was relieved through intravenous and oral administration of calcium treatment in 3d. One case of cutaneous tightness on chest happened， and it was spontaneous remission in a month. The operation time was （102±28.4） min （55-182 min）， intraoperative bleeding was （46±16.6） mL （30-106 mL）， and the drainage tube was removed postoperative 2-7d with an average （4±2.2） d， the postoperative hospitalization was 3-8 d with an average （4±1.1） d. All of the cases were followed-up after operation without low calcium， low parathyroid hormone， hoarseness， and local goiter recurrence. Two cases of hypoparathyroidism returned to normal after oral thyroxine dose adjustment. All the patients were satisfied with the cosmetic results. Conclusions The endoscopic thyroidectomy via chest-breast approach is safe and feasible with good cosmetic results. The subcutaneous Y tunnel， the “upper yellow middle white lower red” appearance on the chest， and the landmark of inverse trapezium on the neck are the key points for creation of operation compartment. Sufficient exposure， stepwise procedure， blunt dissection combined with sharp dissection in the precise gap are the surgical skills for endoscopic thyroidectomy.
ObjectiveTo investigate the risk factors of perioperative anaesthesia management in postoperative headache induced by thyroidectomy. MethodsA 1:1 age and operation time matched case-control design study was performed. General anesthesia patients for elective thyroidectomy with postoperative headache (case group, VAS score >4) and without postoperative headache (control group, VAS score ≤4) were recruited. Univariate and multivariate analyses were performed to analyze the risk factors of postoperative headache after 24 and 48 hours of operation by using SPSS 18.0 software. ResultsA total of 134 patients were included; of which, 67 were in the case group and the other 67 were in the control group. The results of univariate analysis showed that female and administration of flurbiprofen axetil might be the risk factors of postoperative headache. The further multivariate analysis showed that administration of flurbiprofen axetil was significantly associated with decreased postoperative headache (OR=0.387, 95%CI 0.185 to 0.811). ConclusionPerioperative anesthesia management has a certain influence on postoperative headache induced by thyroidectomy. The use of flurbiprofen axetil during operation could reduce the incidence rate of postoperative headache.
Objective To investigate the indications and prevention of complications of total thyroidectomy in the management of thyroid diseases. Methods Eighty five patients who received total thyroidectomy between Jan. 2009 and Dec. 2011 were retrospectively analyzed with regard to the surgical procedures and postoperative complications. There were 46 thyroid cancers， 38 nodular goiters， and 1 Hashimoto thyroiditis. Results The postoperative pathological exam-inations revealed that 9 （19.6%） of 46 thyroid cancers were bilateral， and all of nodular goiters were also bilateral multiple nodule. Bilateral recurrent laryngeal nerves were exposed in all of the patients in which 4 recurrent laryngeal nerves were invaded by cancer and 1 was sacrificed. There were 5 patients whose parathyroids were not identified and protected during the operation. Two patients developed postoperative bleeding and needed reoperation， 6 patients developed hoarseness of whom 5 patients recovered except for the one whose nerve was sacrificed. And in terms of hypoparathyroidism， 33 （38.8%） patients developed transient hypocalcemia related symptoms. The permanent hypoparathyroidism occurred only in 2 patients. Conclusions Total thyroidectomy is a safe procedure in the management of thyroid cancer and bilateral nodular goiter. Exposing the recurrent laryngeal nerve and parathyroid is an effective method to prevent major complica-tions. Invasion of recurrent laryngeal nerve by thyroid cancer might not lead to hoarseness.
Objective To investigate the threshold value for postoperative parathyroid hormone （PTH） that can predict the development of symptomatic hypocalcemia. Methods The patients received total thyroidectomy and all the operations performed by the same team from June 2010 to December 2011 in the thyroid and breast group of department of general surgery，Xuanwu Hospital of Capital Medical University were enrolled in this prospective study. Serum PTH and calcium were tested at 1-hour postoperatively and thereafter every day during hospitalization. Symptoms of hypocalcemia were recorded. Receiver operator characteristic curve was plotted to test the value of PTH assay to predict symptomatic hypocalcemia. Results There were 45 consecutive patients recruited in this prospective study，9 （20.0%） patients remained normocalcemic and 36 （80.0%） patients developed hypocalcemia postoperatively. There were 19 （42.2%） patients who developed symptoms associated with hypocalcemia and needed calcium supplement. The postoperative PTHs for normocalcemic （n=9），asymptomatic （n=17），and symptomatic （n=19） hypocalcemia patients groups were （40.5±23.7） ng/L，（18.3±9.1） ng/L，and （7.6±4.2） ng/L，respectively （P＜0.001）. The PTH value less than 13.4 ng/L could easily predict who were at high risk to develop symptomatic hypocalcemia with sensitivity of 94.7% and specificity of 76.9%. Conclusions This study suggests that a 1-hour postoperative PTH level at 13.4 ng/L can identify those individuals at risk for developing symptomatic hypocalcemia. Therefore，we recommend early calcium supplementation for these patients to decrease their postoperative morbidity from symptomatic hypocalcemia.
ObjectiveTo summarize the variation of parathyroid hormone (PTH) after thyroidectomy and the influence factors of postthyroidectomy hypocalcemia (PHC). MethodsClinical data of 95 patients who underwent thyroidectomy in Affiliated Shengjing Hospital of China Medical University from Jan. 2015 to Dec. 2015 were analyzed retrospectively. ResultsOf the 95 patients, there were 27 patient (28.42%) suffered from PHC (PHC group), and levels of serum calcium in the other 68 patients (71.58%) were normal (normal group). There was no significant difference in levels of serum calcium and PTH between the PHC group and normal group before operation (P > 0.05), but levels of serum calcium and PTH in PHC group were both lower than corresponding index of normal group after operation (P < 0.05). The levels of serum calcium and PTH both decreased in PHC group after operation (P < 0.05), and only PTH level decreased in normal group after operation (P < 0.05). PHC was related with type of operation, who underwent two-side operation had higher risk of PHC (P < 0.05), but there was no significant relationship between PHC and gender or age (P > 0.05). ConclusionsPTH is an important factor for PHC. In addition, it is easier to occur PHC when the operative range become bigger.
Objective To sum up experiences in diagnosis and treatment for Hashimoto′s disease (HD). Methods Clinical records of 78 patients who underwent operations and were diagnosed as Hashimoto′s disease by histologic examination in our hospital from Jan. 1988 to Dec. 1998 were analyzed. Results Seventy females and 8 males, aged 9 to 70 years (average of 41.6 years). HD was coexistent with 10.3% of thyroid gland malignant tumor, 23.1% of adenoma and 30.8% of other thhroid gland diseases. The misdiagnosis rate was 35.9% and missed diagnosis rate was 46.2%. The clinical feature of HD and most common cause of misdiagnosis and missed diagnosis have been discussed. Conclusion It is emphasized that patients with diffuse goiter, palpable nodules, lighty color on scintillation scintigraphy, elevation of antimicosomiaux and antithyroglobuline but no finding on Bus should be highly suspected of having Hashimoto′s disease.
【Abstract】Objective To search for the significance of endoscopic thyroidectomy and parathyroidectomy. Methods Literatures about endoscopic thyroidectomy and parathyroidectomy were collected and reviewed. Results Thyroidectomy and parathyroidectomy may be performed with endoscope or with the help of endoscope. Conclusion By endoscopic thyroidectomy and parathyroidectomy, the patients are lightly injured without scar in the neck. The quality of life is improved.
ObjectiveTo evaluate the value of parathyroid hormone (PTH) in predicting hypocalcemia at different time after thyroidectomy. MethodsThe literatures in CBM, WanFang, CNKI, VIP in Chinese, and OVID, PUBMED, EMBASE, and MEDLINE in English were searched. Hand searches and additional searches were also conducted. The studies of predicting hypocalcemia after thyroidectomy by detecting postoperative PTH at different time were selected, and the quality and tested the heterogeneity of included articles were assessed. Then the proper effect model to calculate pooled weighted sensitivity (SEN), specificity (SPE), positive likelihood ratio (LR+), and negative likelihood ratio (LR-) were selected. The summary receiver operating characteristic (SROC) curve was performed and the area under the curve (AUC) was computed. ResultsTwenty-three articles entered this systematic review, 21 articles were English and 2 articles were Chinese. Fifteen of 23 articles were designed to be prospective cohort study (PC) and 8 of 23 articles were retrospective study (Retro). These articles were divided into two groups. Group 1 was the studies of detecting postoperative PTH in 1 hour, which included 2 012 cases (494 of them occurred hypocalcemia). Group 2 was the studies of detecting postoperative PTH between 4-12 hours, which included 693 cases (266 of them occurred hypocalcemia). The publication bias of 2 groups were smaller that founded through the literature funnel. Meta analysis showed that in addition to merge SEN, between the 2 groups with merge SPE, LR+, LR-, and AUC differences were statistically significant (P < 0.01);the forecast effect of group 1 was better than group 2, and the AUC was the largest area when the PTH value in 1 hour after operation was below 16 ng/L. ConclusionDetection of postoperative PTH value is an effective method for predicting postoperative hypocalcemia. The 1 hour after operation for detecting PTH value below 16 ng/L to predict postoperative hypocalcemia have the best effect.
ObjectiveTo investigate the feasibility and safety of using a custom-made needle-assisted retractor derived from a nerve monitoring monopolar ball-tip probe in endoscopic thyroidectomy by a gasless unilateral axillary approach (GUA). MethodsA retrospective analysis was performed on the clinical data and surgical procedures of 50 consecutive patients who underwent endoscopic thyroidectomy by GUA by a single surgeon in the Department of Thyroid Surgery, China-Japan Union Hospital of Jilin University from April 2023 to December 2023. Surgical experiences and operative techniques were summarized. ResultsAmong the 50 patients, there were 48 females and 2 males, with an age of (35.16±7.56) years. Forty-seven patients were diagnosed with papillary thyroid carcinoma, with a tumor diameter of (0.69±0.52) cm; 3 patients had benign nodules, with a maximum diameter of (2.67±0.58) cm. All patients underwent unilateral thyroid lobectomy (patients with malignancy additionally underwent central neck dissection). All surgery was successfully completed without conversion to open surgery. The operative time was (156.12±34.27) min. Postoperative complications included temporary hoarseness in 2 patients, subcutaneous effusion in 2 patients, and ipsilateral upper limb numbness in 1 patient. All complications recovered within one month. ConclusionsThe results of this study suggest that the in endoscopic thyroidectomy by a GUA approach demonstrates good feasibility and safety. Furthermore, it helps reduce the difficulty of the procedure, providing effective support for surgeons, especially beginners, to rapidly master this technique.
Objective To compare the therapeutic effects between endoscopic thyroidectomy by anterior chest approach and modified Miccoli thyroidectomy. Methods Sixty patients with thyroid goiter were performed endoscopic thyroidectomy by anterior chest approach (endoscopic thyroidectomy by anterior chest approach group, n=30) and modified Miccoli thyroidectomy (modified Miccoli group, n=30) respectively. The operative time, the drainage volume, cosmetic benefit, the postoperative hospitalization time, the expenses of hospitalization and postoperative complications of two groups were compared. Results The operative time and the drainage volume after operation of endoscopic thyoidectomy by anterior chest approach group were significantly more than modified Miccoli group 〔(99.9±23.4) min vs. (74.0±29.6) min; (68.6±8.7) ml vs. (40.9±6.1) ml, respectively〕, Plt;0.05. The cosmetic benefit score of endoscopic thyoidectomy by anterior chest approach group was higher than that of modified Miccoli group 〔(4.7±0.2) points vs. (3.7±0.1) points〕, Plt;0.05. The postoperative hospitalization time and expenses of hospitalization were no significant differences between the two groups 〔(6.5±1.7) d vs. (5.5±0.9) d; (9 328.3±1 107.1) yuan vs. (8 568.2±1 032.3) yuan, respectively〕, Pgt;0.05. One case had transient hoarseness in 2 groups respectively, no other complications happened. Conclusions Modified Miccoli operation is both minimally invasive and cosmetic, but endoscopic thyroidectomy by anterior chest approach has better cosmetic benefit, which can release patients’ psychological trauma. The patients with specific cosmetic demand may choose endoscopic thyroidectomy by anterior chest approach.
