001). The cancer-specific mortality (CSM) and all-cause mortality (ACM) rates per 1,000 person-years were higher in patients with follicular thyroid carcinoma (FTC) and in those with N1 stage and M1 stage disease. Furthermore, we observed a significant synergic effect between histology subtype and N stage, as well as histology subtype and M stage for the CSM of DTC (RERI =48.806, AP =0.853, SI =7.565; RERI =37.889, AP =0.430, SI =1.771, respectively). However, no synergic effect was observed in the case of the N stage and M stage for the CSM of DTC (RERI =7.928, AP =0.084, SI =1.093).

Patients with histology subtype of FTC and N1 stage, histology subtype of FTC and M1 stage had significant additive synergic effects on DTC prognosis for CSM.

The rate of level V metastases is significantly low and the necessity of routine level V dissection for papillary thyroid microcarcinoma (PTMC) with clinically lateral lymph node metastasis (LNM) is still controversial.

This study enrolled 114 consecutive PTMC patients with clinically suspected lateral LNM (N1b) who underwent modified radical neck dissection (levels II to V) at Xiangya Hospital of Central South University from September 2016 to July 2019. Univariate and multivariate analyses were performed to investigate the predictive factors of level V metastasis. The area under the receiver operating characteristic (ROC) curve (AUC), accuracy, specificity and sensitivity were used to determine the predictive value.

The overall and occult rate of level V metastasis were 29.82% (34/114) and 7.02% (8/114), respectively. Univariate analysis showed that level V metastasis was significantly associated with gross extrathyroidal extension (ETE), level IV metastasis and 2-level simultaneous metastasis (all P<0.05). Gross ETE (OR =11.916, 95% CI, 1.404-102.19; P=0.023) and level IV metastasis (OR =8.497, 95% CI, 2.119-34.065; P =0.03) served as independent predictors of level V metastasis in N1b PTMC patients. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of gross ETE and level IV metastasis in predicting the level V metastasis were 25.3%
82.4%, 97.5%
73.8%, 82.69%
76.32%, 80%
57.04% and 75%
90.77%, respectively. The AUC of gross ETE was lower than level IV metastasis (0.605
0.781, P=0.041).

Routine level V dissection is necessary in N1b PTMC patients with level IV metastasis or gross ETE. Compared with gross ETE, level IV metastasis is superior in predicting level V metastasis.

Incidental excision of parathyroid glands is a common event during thyroid surgery and in spite the divergent results that can be obtained from the literature about its clinical significance, all efforts must be used to their preservation. Due to the autofluorescence emitted by parathyroid glands, authors began to use a custom device to inspect thyroidectomy specimens for incidentally removed parathyroid tissue; the results of using this device are presented in this manuscript.

Specimens of 40 consecutive thyroid surgeries were inspected. Localization of suspect high-fluorescence spots were recorded for confirmation with a pathological exam. Determinations of calcium and parathyroid hormone (PTH) were completed prior to surgery and at 24 hours and 15 days after the operation.

Patient age ranged from 36 to 83 years and were predominantly female (82.5%). Calcium values at 24 hours post-operation varied between 7.1 and 9.5. The PTH values ranged between 3 and 77. Thirteen patients (32.5%) presented with bily-removed glands.
Although internal mammary vessels are considered the best recipients for free flap breast reconstruction, they present the notable drawback of limited accessibility. The aim of this study was to develop a minimally invasive surgical technique for the dissection of internal mammary vessels as recipients for breast reconstruction.

From 2008 to 2018, we performed 32 unilateral microsurgical breast reconstructions (mean patient age 40.1±8.7 years; range, 23-58 years). As internal mammary vessels were exclusively used as recipients, they were dissected using a technique of minimally invasive video-assisted thoracoscopic surgery (VATS) developed in our hospital.

The mean surgery time was 5.4±0.55 hours (range, 4.5-6.5 hours), and the mean duration of VATS dissection of internal mammary vessels was 20.6±2.9 minutes (range, 16-27 minutes). Of the specific complications associated with VATS, we only observed reductions in forced expiratory volume in the first second of >15% in 3 patients (9.4%), 10-15% in 8 patients (25%), and <10% in 21 patients (65.63%). We did not have any cases of significant bleeding or postoperative infection in this series of patients. With regard to aesthetic complications, we observed 1 and 2 cases of total necrosis and partial necrosis of the deep inferior epigastric perforator (DIEP) flap, respectively and 2 cases of partial necrosis of supercharged transverse rectus abdominis muscle flap.

Endoscopic dissection of internal mammary vessels is a simple and feasible technique. When performed by experienced surgeons, it is a fast procedure that is associated with low rate of complications.

Since 2004, uniportal video-assisted thoracic surgery (VATS) approach was progressively widespread and also applied in the treatment of thymoma, with promising results. We report the first series of patients who undergone uniportal VATS thymectomy using a homemade glove-port with carbon dioxide (CO
) insufflation. The aim of this article is to analyze the safety and feasibility to perform an extended thymectomy (ET).

A prospective, single-centre, short-term observational study including patients with mediastinal tumours undergoing scheduled uniportal VATS resection using a glove-port with CO
. Operations were performed through a single incision of 3.5 cm at the fifth intercostal space, right or left anterior axillary line. A 5 mm-30° camera and working instruments were employed through a glove-port with CO
.

Thirty-eight patients (20 men; mean age 61.6 years) underwent ET between September 2016 and October 2019. Sodium 3-carboxypropanoate Thirteen patients had a history of Myasthenia Gravis (MG) with thymoma and 8 had incidental findings of thymoma.
