Project description:Recently, transoral endoscopic thyroidectomy (TOET) is receiving attention because it is regarded as a true minimally invasive surgery in that it does not leave scars on any part of the body and the area of flap dissection is similar to that of open surgery. In this study, we present the surgical procedures and initial outcomes of TOET in the treatment of papillary thyroid microcarcinoma (PTMC) patients.The medical records of patients who underwent TOET for PTMC between July 2016 and February 2017 were retrospectively reviewed. Indication of TOET was PTMC without capsular invasion or lymph node metastasis on preoperative imaging studies.Ten female patients were enrolled. Seven patients underwent thyroid lobectomy and three patients underwent isthmusectomy. The mean age and tumor size was 43.3 ± 11.5 years and 0.6 ± 0.2 cm, respectively. Operation time for lobectomy and isthmusectomy was 121.1 ± 30.7 (range, 65-148) and 90.0 ± 9.2 minutes (range, 82-100 minutes), respectively. The mean number of retrieved lymph nodes was 2.7 ± 1.7. Two patients had transient vocal cord palsy, which recovered in three months. There was no case with subcutaneous emphysema, surgical site infection, postoperative bleeding, or mental nerve injury.TOET was feasible and could be performed safely for PTMC. TOET might become a new treatment option for the patients who do not want to leave visible scars on the body.

Project description:Transoral approach for thyroidectomy recently gains a lot of attention among the thyroid surgeons, with the merits of cosmetic outcomes and minimal flap dissection. We've successfully introduced the robotic surgical system to the transoral approach for thyroidectomy. For transoral robotic thyroidectomy, we made 3 incisions in the gingival-buccal sulcus for three intraoral ports. An additional axilla port was inserted for counter-traction and later drain insertion. Herein, our unique procedures of transoral robotic thyroidectomy (TORT) are described in the treatment of a patient with papillary thyroid carcinoma.

Project description:IntroductionThyroidectomy and thyrotropin suppressive therapy is the widely used surgical treatment for papillary thyroid carcinoma (PTC) patients. However, systematic metabolic changes of post-operative PTC patients were rarely reported.MethodsHere, untargeted metabolomic detection of cohorts from PTC before (t0) and 1-month-after (t1) thyroidectomy, were performed to characterize circulating metabolic signatures after surgical treatment.ResultsOur results showed PTC patients exhibited lower thyroid stimulating hormone degree, higher total thyroxine, and significant lipid-related metabolic alternations after thyroidectomy, which included 97 upregulations (including 93 lipids) and 5 downregulations (including 2 lipids and 3 nucleotides). Enrichment of metabolic pathways mainly included biosynthesis of fatty acids, purine metabolism, and linoleic acid metabolism. We also demonstrated that differential surgical approaches (hemi- and total thyroidectomy) and post-operative complication phenotypes (insomnia, fatigue), might lead to characteristic metabolic signatures.DiscussionThis study revealed dynamic changes of metabolite characteristics of PTC patients after surgical treatment, which were associated with clinical thyroid function parameters, surgical approaches, and complication occurrence. It enlightened us to pay more attention on the post-operative metabolic dysregulation of PTC patients and their long-term qualities of life, so as to provide cautious clinical decisions on surgical choices, treatments, and follow-up details.

Project description:BackgroundPapillary thyroid carcinoma of isthmus (PTCI) has a more aggressive nature, a higher rate of lymph node metastasis and tumor recurrence. Clinicians have different preferences for the surgical approach to PTCI, but there are no definitive guidelines. The purpose of this article is to compare the oncologic outcomes and complications of total thyroidectomy and less-than-total thyroidectomy for PTCI using meta-analysis.MethodsWe searched PubMed, Embase, Cochrane Library, and Web of Science databases for articles that met the inclusion criteria, with an unlimited start date and an end date of February 19, 2023. Exclusion criteria were applied to filter out articles for further analysis. Ultimately, seven articles were used for analysis, all of which were retrospective studies. The MINORS scale was adopted to evaluate the quality of the included literature, and Review Manager 5.4 was used for data analysis.ResultsA total of 814 patients were included in the seven articles, including 401 in the less-than-total thyroidectomy group (trial group) and 413 in the total thyroidectomy group (control group). The results of the meta-analysis showed that there was no significant difference in the tumor recurrence rate between the two groups after total thyroidectomy or less-than-thyroidectomy for PTCI (odds ratio, 1.51; 95% confidence interval: 0.49, 4.65; P=0.47), and there was no statistical difference in the incidence of all postoperative complications between the two groups.ConclusionsThere may be some limitations in this analysis, such as publication bias and the fact that the included articles were all retrospective studies with a certain degree of heterogeneity. PTCI patients with early staging and no significant lymph node metastases may be able to choose a more conservative surgical approach, which is less-than-total thyroidectomy. Patients with relatively late staging and significant preoperative lymph node metastases or extra thyroidal extension may opt for total thyroidectomy plus lymph node dissection in the central region and, if necessary, lymph node dissection in the lateral cervical region.

Project description:Objective：The safety of endoscopic thyroidectomy in patients with Hashimoto's thyroiditis (HT) is a matter of concern. This study aimed to assess the effect of concomitant HT on the feasibility of endoscopic thyroidectomy in patients with papillary thyroid carcinoma (PTC).MethodsThis study is an observational, retrospective study. All patients were histopathologically diagnosed with HT. The study group consisted of 44 patients (40 %) with PTC who also had HT, whereas the remaining 66 patients (60%) without HT were assigned to the control group. The number of dissected lymph nodes, mean operation time, thyroid volume, blood loss, TSH level, and postoperative complications were recorded and statistically analysed.ResultsOne patient underwent conversion to open thyroidectomy because of recurrent laryngeal nerve (RLN) transection. Another patient required reoperation owing to postoperative haemorrhage. Statistically significant differences were observed in mean operation time (105.4 ± 10.7 vs 98.2 ± 7.4 min, P = 0.0001),mean thyroid lobe volume (12.2 ± 5.8 vs 9.6 ± 3.5 mL [mL], P = 0.0041), TSH level(4.1 ± 1.5 mIU/L vs 3.4 ± 0.9 mIU/L, P ＝ 0.0028), and the number of dissected lymph nodes between groups (4.1 ± 1.5 vs 3.4 ± 0.9,P = 0.0028). The estimated mean blood loss (31.5 ± 6.8 vs 29.5 ± 3.9 mL, P = 0.0529) and rate of complications (15.9% vs 10.6%, P = 0.4136) did not show statistically significant differences between groups.ConclusionThe coexistence of PTC and HT increases the operation time and difficulties in endoscopic thyroidectomy but does not affect postoperative outcomes. Endoscopic thyroidectomy can be safely performed with acceptable complication rates.

Project description:Background:Transoral endoscopic thyroidectomy provides access via the oral vestibule and gas insufflation to provide reliable remote access surgery to perform a total thyroidectomy. The da Vinci SP (Intuitive Surgical Inc., Sunnyvale, CA, USA) is a next generation flexible single port system that offers unique advantages over previous robotic rigid systems. Here we sought to evaluate the feasibility of performing transoral thyroidectomy with this next generation flexible robotic system. Methods:Cadaveric dissection with gas insufflation to test the feasibility of performing transoral thyroidectomy with the da Vinci SP. Results:A 2 cm incision was made in the oral vestibule and the working space created with a 1cm central port and two lateral 5 mm ports. Then an extra small wound protector (Applied Medical, Rancho Santa Margarita, CA) was placed through the central incision after closure of the 5 mm ports. The robotic system was then deployed through the wound protector while insufflation was maintained at ~6 mmHg. Three instrument arms were deployed. A fenestrated bipolar was used to grasp the thyroid gland while Maryland bipolars and monopolar scissors were used to mobilize each hemi lobe of the thyroid. The recurrent laryngeal nerves were seen and preserved bilaterally. After completion of the surgery and removal of the wound protector the vestibular incision was measured to be 3 cm. Further dissection to identify the mental nerves identified each nerve to be >1 cm from the lateral extent of the central incision. Conclusions:In summary, it is feasible to perform a total thyroidectomy with gas insufflation utilizing this next generation flexible robotic system. Further evaluation will be needed to validate the clinical applicability of this technique.

Project description:UnlabelledRecently, a transoral robotic-assisted technique to access the thyroid gland has been introduced. Despite the advantages this approach may have over other minimally invasive and robotic-assisted techniques, we found that the placement of the camera through the floor of mouth led to restricted freedom of movement. We describe our modification to this technique to overcome this problem. In a study using two fresh human cadavers, the camera port of the da Vinci robot was placed in the midline oral vestibule instead of the floor of the mouth. A transoral thyroidectomy and central neck dissection was successfully performed. Our modification led to an unfettered view of the central neck and allowed for a total thyroidectomy and central neck dissection. Our modification of transoral robotic-assisted thyroidectomy provides superior access to the central compartment of the neck over other robotic-assisted thyroidectomy techniques.Electronic supplementary materialThe online version of this article (doi:10.1007/s11701-011-0287-2) contains supplementary material, which is available to authorized users.

Project description:Background: Transoral thyroid surgery represented by the da Vinci system is attracted attention and performed by several institutions. However, the current available da Vinci system still has some limitations to be improved for transoral thyroid surgery including high cost of equipment and expendables, larger diameter scope and instruments and no tactile sensation. It triggered us interest in more easily available robotic scope holder. Soloassist II (AktorMed GmbH, Barbing, Germany) is an active endoscope holder system which is controlled by a joystick. It has total six joints: three joints which are controlled by computer, one is controlled by manual and two act as a gimbal joint following the movement of the main body.Materials and methodsWe tried transoral endoscopic thyroidectomy using Soloassist II (AktorMed GmbH, Barbing, Germany) in December 2017 in our hospital.ResultsWe successfully performed four thyroid lobectomies in four patients with Soloassist II. We refined and described surgical procedures in each step using video clips. It provided an excellent vibration-free stable surgical view which enabled fatigue-free work, without shaking or tilting the horizon. The surgeon could perform transoral endoscopic thyroid surgery with only one assistant surgeon. Docking and preparation time for Soloassist was within 10 min in all four patients. The setup and dismantling could be performed parallel to the usual workflow. No complication was reported by any patient.Conclusions: The robotic scope holder (Soloassist II) seems to be safe and feasible equipment for performing transoral endoscopic thyroid surgery. Several possible advantages could be expected with this robotic scope holder.

Project description:Currently, there is a lack of efficient recurrence prediction methods for papillary thyroid carcinoma (PTC). In this study, we enrolled 202 PTC patients submitted to total thyroidectomy and radioiodine therapy with long-term follow-up (median = 10.7 years). The patients were classified as having favorable clinical outcome (PTC-FCO, no disease in the follow-up) or recurrence (PTC-RE). Alterations in BRAF, RAS, RET, and TERT were investigated (n = 202) and the transcriptome of 48 PTC (>10 years of follow-up) samples was profiled. Although no mutation was associated with the recurrence risk, 68 genes were found as differentially expressed in PTC-RE compared to PTC-FCO. Pathway analysis highlighted a potential role of cancer-related pathways, including signal transduction and FoxO signaling. Among the eight selected genes evaluated by RT-qPCR, SLC2A4 and GADD45B showed down-expression exclusively in the PTC-FCO group compared to non-neoplastic tissues (NT). Increased expression of GADD45B was an independent marker of shorter disease-free survival [hazard ratio (HR) 2.9; 95% confidence interval (CI95) 1.2-7.0] in our cohort and with overall survival in the TCGA dataset (HR = 4.38, CI95 1.2-15.5). In conclusion, GADD45B transcript was identified as a novel prognostic marker candidate in PTC patients treated with total thyroidectomy and radioiodine therapy.
