RESUMO
INTRODUCTION: Thyroid tumours are a common condition and open surgery is a conventional method for treating benign thyroid tumours when surgery is indicated. In this study, we evaluate the outcomes of benign thyroid tumour treatment using transoral endoscopic thyroidectomy via vestibular approach (TOETVA) and compare the results with those of conventional open thyroidectomy (COT). PATIENTS AND METHODS: We conducted a prospective cohort study between 100 patients who underwent TOETVA and 100 who underwent COT surgery for benign diseases from June 2018 to December 2021 in our hospital. Outcomes between the two groups, including post-operative complications, operative time and length of stay, were compared. RESULTS: The surgical time in the TOETVA group was significantly longer than in the COT group. The operative time of lobectomy in the TOETVA and COT groups was 77.5 ± 13.3 and 51.5 ± 4.2 min, respectively, with a P < 0.001. The operative time of total thyroidectomy in the TOETVA and COT groups was 108.1 ± 7.0 and 65.0 ± 4.1 min, respectively, with a P < 0.001. There was no difference in post-operative length of stay between the two groups. In TOETVA group, there were no patients who converted to open surgery. Amongst all 200 patients in the study, there were no cases of post-operative bleeding. The transient hypoparathyroidism rate after surgery in the TOETVA and COT groups was 3% and 2%, respectively, with no statistically significant difference (P = 0.651). Similarly, the transient recurrent laryngeal nerve injury rate showed no difference between the two groups, with rates of 5% and 4% in the TOETVA and COT groups, respectively (P = 0.733). There were no cases of post-operative infection in either group in our study. At 3 months postoperatively, the cosmetic satisfaction were significantly higher in the endoscopic groups than in the conventional group (P < 0.001). CONCLUSIONS: TOETVA is a safe and effective method, with a low complication rate and optimal aesthetic results compared to traditional surgery to treat benign thyroid tumours.
RESUMO
BACKGROUND: Although transoral thyroidectomy has become popular in thyroid surgery, transoral robotic thyroidectomy (TORT) has only been successfully applied in a very small number of medical centers worldwide.[1,2,3,4,5] In this video, we show a three-port TORT without an axillary incision for papillary thyroid carcinoma. PATIENT AND METHODS: A 35-year-old female with cT1aN0M0 papillary thyroid carcinoma had a strong motivation to proceed with surgery but avoid external neck incisions. Thus, we decided to perform a hemithyroidectomy with isthmusectomy using a transoral robotic approach, employing the da Vinci Xi surgical system. RESULTS: The operation was completed successfully without conversion to open surgery. The working space creation time, docking time, and console time were 30 min, 40 min, and 130 min, respectively. The pathological results were papillary thyroid carcinoma with 6- and 5-mm tumors. The patient was discharged 4 days after surgery without any complications such as bleeding, infection, mental nerve damage, permanent hoarseness, or hypoparathyroidism. The patient was completely satisfied with the cosmetic result. CONCLUSION: Three-port TORT without an axillary incision is a promising approach with optimal cosmetic outcomes. For Vietnam, a developing country, success in the application of TORT using the new da Vinci Xi robotic platform for thyroid cancer is an important milestone in the development of thyroid surgery.

BACKGROUND: Recently, transoral endoscopic thyroidectomy via the vestibular approach (TOETVA) has become popular worldwide.1-3 After controlling for the technique, the authors used the transoral endoscopic approach to modified radical neck dissection (MRND) for papillary thyroid carcinoma with clinically positive lymph nodes in the lateral compartments. To the best of their knowledge, the authors report the first case of TOETVA for MRND. PATIENT: A 27-year-old woman had a diagnosis of cT1aN1bM0 right papillary thyroid carcinoma (metastatic to a small right level 4 lymph node). Therefore, total thyroidectomy, bilateral central neck dissection, and MRND of right levels 2, 3, and 4 were performed via the transoral endoscopic approach. METHODS: Total thyroidectomy and bilateral central lymph node dissections were performed based on the three-trocar Anuwong technique.4 Then, the fourth incision was made near the sixth teeth in the right oral vestibular area for insertion of the fourth 5-mm trocar, which was used to expose the lateral lymph compartment and to perform right MRND easily. RESULTS: The operation was completed successfully without conversion to open surgery. The total operative time was 170 min, and the operating time for MRND was 55 min. The numbers of harvested lymph nodes were 7 and 8 in the central and right lateral compartments, respectively. The numbers of metastatic lymph nodes were 2 and 1 in the central and lateral compartments, respectively. No major postoperative complications occurred. CONCLUSION: Transoral endoscopic MRND of levels 2, 3, and 4 can be feasible and safe for highly selected patients.

OBJECTIVES: The objective of this study was to report the feasibility and safety of a novel 4-trocar approach for transoral endoscopic thyroidectomy via the vestibular. METHODS: In this study, we first used 4 trocars via vestibular area to perform transoral endoscopic thyroidectomy. We reported the safety and surgical feasibility of transoral endoscopic thyroidectomy using a 4-trocar technique in our institute from February 1, 2020, to May 10, 2020. RESULTS: Transoral endoscopic thyroidectomy via the vestibular approach using 4 trocars was carried out in 5 patients. No complications such as bleeding, mental nerve injury, recurrent laryngeal nerve injury, or hypoparathyroidism were reported. All patients were completely satisfied with the cosmetic results. CONCLUSIONS: Transoral endoscopic thyroidectomy with 4 trocars via vestibular approach is an effective and feasible method. Markedly, this technique can assist surgeons to expose and preserve both parathyroid glands and recurrent laryngeal nerve easily when performing transoral endoscopic thyroidectomy.

This study investigated the effects of different mixing ratios of crop residues and biochar with liquid digestate from anaerobically treated pig manure on CH4, CO2, and N2O emissions over 84 days in a system of passive aeration composting, resembling typical Vietnamese solid manure storage conditions. Two treatments with solid manure were included for comparison. The results showed that C losses through CH4 and CO2emissions accounted for 0.06-0.28% and 1.9-26.7%, respectively, of initial total C. CH4 losses accounted for just 0.4-4.0% of total C losses. Total N losses accounted for 27.1-40% of initial total N in which N2O emissions corresponded to 0.01-0.57% of initial total N, and hence accounted for only 0.1-1.8% of total N losses. It is assumed that the remainder was either the result of denitrification losses to N2or ammonia volatilization. The composting of biochar (B) or crop residue with digestate (D) showed significantly lower CH4 and N2O emissions compared with composting manure (M) (p < .05). The composting of digestate with biochar showed significantly lower CO2and CH4emissions and significantly higher N2O emissions compared to the composting of digestate with rice straw (RS) (p < .05). The combined composting of digestate with biochar and rice straw (D + B + RS5:0.3:1) showed significantly reduced N2O emissions compared with composting digestate with biochar with alone (p < .05). Composting sugar cane bagasse (SC) with digestate (D + SC) significantly reduced CH4and N2O emissions compared with the composting of rice straw with digestate (D + RS3.5:1 and D + RS5:1) (p < .05).
