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.
ObjectiveTo explore the risk factors and bleeding points associated with postoperative hemorrhage after thyroidectomy and provide clinical basis for prevention of postoperative bleeding.MethodsThe clinical data of 21 patients with postoperative hemorrhage and 63 patients without postoperative hemorrhage who underwent thyroidectomy from Nov. 2010 to Nov. 2017 in West China Hospital were retrospectively analyzed.ResultsUnivariate analysis showed that hypertension, maximum tumour dimension, lymph node metastasis, recurrent laryngeal nerval infiltration, T stage, N stage, serum triglyceride, and serum high density lipoprotein were significantly associated with postoperative hemorrhage (P<0.05). Multivariate analysis showed that lymph node metastasis (OR=16.219, P=0.002) and low serum high density lipoprotein (OR=0.035, P=0.006) were risk factors for postoperative hemorrhage. Among the patients with postoperative bleeding, the most common five bleeding sites were: ribbon muscle and sternocleidomastoid muscle (both was 19.2%), esophageal tracheal surface blood vessels (11.5%), thyroid bed (7.7%), and larynx recurrent paravascular small vessels (7.7%).ConclusionsLymph node metastasis and serum HDL are independent risk factors of hemorrhage after thyroidectomy. The predilection site for postoperative bleeding is mainly the neck muscle.
ObjectiveTo investigate the clinical value of cervical vascular color Doppler ultrasound for dignosis of nonrecurrent laryngeal nerve before thyroid surgery. MethodsThere were 1931 cases of thyroid patients treated between January 2010 to Jule 2014, group these patients according to the results of preoperative chest radiograph examination, the chest radiograph shows abnormal vessels image were group A (45 cases), no abnormalities were group B (1886 cases). Before operaton, made patients of group A to have routine carotid duplex ultrasound to identify whether the right subclavian artery abnormalities. All patients were exposed to conventional methods of recurrent laryngeal nerve during surgery. ResultsThe 45 patients of group A, chest angiography showed 17 cases with right subclavian artery abnormalities, they were confirmed that all the 17 patients were nonrecurrent laryngeal nerve by surgery, no damage cases. The other 28 cases showed a normal right subclavian artery and no cases of nonrecurrent laryngeal nerve. The 1886 patients in group B, surgical exploration found four cases with nonrecurrent laryngeal nerve, injury in 1 case. The 21 patients whose nonrecurrent laryngeal nerve were on the right side, there were no left side with nonrecurrent laryngeal nerve and no co-exist cases of nonrecurrent and recurrent laryngeal nerve. The average exposure time of nonrecurrent laryngeal nerve in patients of group A (17 cases) was significantly shorter than that group B[(4.28±1.08) min vs. (15.50±2.08) min, t=-15.978, P=0.000]. ConclusionsThe cervical vascular color Doppler ultrasound examination before thyroid surgery can be adjuvant used, if there is the right subclavian artery abnormalities, it showes that there is the right side nonrecurrent laryngeal nerve. So as to effectively prevent the damage of nonrecurrent laryngeal nerve during thyroid surgery.
Objective To evaluate if performing thyroidectomy through small incision has any notable aesthetic impact on patients compared with larger incision. Methods Thirty consecutive patients underwent thyroidectomy were enrolled from March 2008 to June 2008 in this prospective randomized pilot study. The incision length was 6 cm in the small incision group and 9 cm in the larger incision group. After 3 years follow-up，the scar aesthetics were evaluated by patients and surgeons using the Patient and Observer Scar Assessment Scale （POSAS），Vancouver Scar Scale （VSS），respectively. Digital photographs about scars were taken and assessed by non-research related viewers. Results There were 13 cases who received scar aesthetic assessment in both groups. The demographic characteristics of both groups were comparative. The overall patients’ satisfactions for the small incision group and the larger incision group were （2.5±1.9） scores and （2.2±1.5）scores， respectively （P=0.55）. There were no significant differences in scar assessment scale score as for other scar assessment scales （including VSS score，PSAS score，and OSAS score） between the two groups. The evaluation of digital photographs about scars by non-research related viewers was no significant difference （P＞0.05）. Conclusion Larger cervical scar in thyroidectomy does not decrease patients’ satisfaction with their scar results.
Objective To understand anatomy of parathyroid gland and explore its application value in protection of parathyroid gland function during thyroidectomy. Methods The literatures, which were associated with the parathyroid anatomy and hypoparathyroidism were collected. The origin, function, anatomical location, number, blood supply, lymphatic system of the parathyroid gland and its relationship with surrounding tissues of parathyroid gland and its clinical significance in the thyroidectomy, were reviewed. Results The position of the superior parathyroid gland was relatively constant, and the inferior parathyroid gland was more likely to be ectopic. The number of the parathyroid gland was uncertain. The mainstream view was that the arterial supply of the parathyroid glands was mainly ensured by the inferior thyroid artery, a few by anastomosis of the superior and inferior thyroid arteries, or by the superior thyroid artery. However, the alternative view was that the blood supply of the parathyroid gland was not mainly derived from the inferior thyroid artery. The parathyroid gland was not easily distinguished from the adipose tissue and lymph node. Whether there was an independent lymphatic system in the parathyroid gland was still controversial. In the thyroidectomy, the parathyroid gland and its blood supply were reserved or protected by distinguishing from the Zuckerkandl tubercle, recurrent laryngeal nerve, and parathyroid specific attachment fat, which were identified by utilizing of the nanocarbon, loupe magnification, etc.. Especially in the central lymph neck dissection, the main thyroid artery trunk and its important branches should be carefully dissected or retained through the gentle capsular dissection and the correct use of energy devices for vessel sealing. The parathyroid gland in situ was reserved according to the parathyroid type. If it was not possible to be preserved, the parathyroid autotransplantation was necessary during the thyroidectomy. Conclusions Understanding origin and location of parathyroid gland, it could provide a direction for searching parathyroid gland during thyroidectomy. Being familiar with blood supply of parathyroid gland makes it possible to protect blood vessel and preserve parathyroid gland. Gentle capsular dissection, rational use of energy device, and indocyanine green angiography seem to be more important. Number of parathyroid gland allows us to treat each parathyroid gland as the last one, if it is not preserved in situ , parathyroid gland need to be autografted to avoid hypoparathyroidism.
ObjectiveTo compare the effect of robotic thyroidectomy and endoscopic thyroidectomy on the voice function. MethodsThe clinical data of 181 patients with differentiated thyroid cancer admitted to Panzhihua Central Hospital of Sichuan Province from March 2022 to June 2023 were analyzed retrospectively. According to the operative mode, this patients were divided into two groups: the endoscope group (n=91) and the robot group (n=90). The subjective and objective acoustic indicators were compared between the two groups at 1 day before operation and 1 week, 1 month and 3 months after operation. ResultsThere were no significant difference in voice handicap index (VHI)-10 scores between the two groups at different time points before and after operation (P>0.05). There were no significant difference of VHI-10 scores between preoperative and different postoperative phases in the robot group (P>0.05). The score of VHI-10 at different postoperative phases in the endoscopic group was higher than that at 1 d before operation (P<0.05). The incidence of voice dysfunction (VHI-10 score ≥8) was 1.1% (1/90), 1.1% (1/90) and 0.0% (0/90) in the robot group, 1.1% (1/91) , 2.2% (2/91) and 0.0% (0/91) in the endoscope group at 1 week, 1 month and 3 months after operation respectively, there were no significant difference between the two groups (P>0.05). The fundamental frequency of patients in the endoscopic group was lower than that at 1 d before operation (P<0.05), and there was no significant difference between each phase after operation and at 1 d before operation of fundamental frequency in the robot group (P>0.05). The fundamental frequency of patients in the endoscopic group was lower than that in the robot group at 1 week after operation (P<0.05). The maximum phonation time of each phase after operation in the robot group was not significantly different from that at 1 d before operation (P>0.05). The maximum phonation time of 1 week after operation in the endoscopic group was shorter than that at 1 d before operation (P<0.05) and also shorter than that in the robot group (P<0.05). There were no significant difference in fundamental frequency perturbation, amplitude perturbation, harmonic noise ratio and voice disorder severity index between the two groups at different phases before and after operation (P>0.05). ConclusionCompared with endoscopic thyroidectomy, the voice function of robotic thyroidectomy via bilateral axillary breast approach is better.
