Quality of Life in Patients Undergoing Endoscopic Thyroidectomy Versus Conventional Open Thyroidectomy: Interim Results From Randomized Trial.

We determined whether endoscopic thyroidectomy (ET) is associated with better health-related quality of life (QoL) compared with open thyroidectomy. We randomly assigned 28 patients aged older than 18 years, Bethesda IV or less on cytology and gland volume of <40 mL to undergo hemithyroidectomy through either open or endoscopic (axillo-breast approach/bilateral axillo-breast approach) technique. The primary outcome was QoL scores on the Short Form-36 and Thyroid-Specific Questionnaire at 2, 6, and 12 weeks postsurgery. Secondary outcomes were postoperative complications, hospital stay, and pain scores. The generic QoL scores based on Short Form-36 were statistically nonsignificant between the two groups. QoL scores based on Thyroid-Specific Questionnaire were statistically significant (P < 0.05) favoring open thyroidectomy in the following domains: (1) numbness at 2, 6, and 12 weeks (P = 0.04, 0.004, and 0.005, respectively), (2) shoulder impairment at 2 weeks (P = 0.017), and (3) favoring ET in cosmesis at 6 and 12 weeks (P = 0.037 and 0.02, respectively). ET has longer operative time (104.6 ± 25.4 vs 123 ± 8.9 min; P = 0.03), longer hospital stays (2.8 ± 0.4 vs 2.4 ± 0.5; P = 0.056) and higher pain scores at 2 and 6 weeks (P = 0.007 and 0.012, respectively) but decreased intraoperative bleeding (33.5 ± 6.4 vs 29.1 ± 3.7 mL; P = 0.037). ET has higher cosmetic satisfaction, increased numbness, and shoulder movement impairment during short-term postsurgery follow-up. Both techniques are similar in impacting general physical, mental, and social health-related QoL. (Clinical Trials Registry of India, Reg. No. CTRI/2020/07/026374).

A prospective study to assess cervical scar satisfaction following conventional open thyroidectomy for thyroid cancer.

Conventional open thyroidectomy (COT) remains a common method of thyroidectomy in many parts of the world for various reasons. In this prospective (cross-sectional) study, we evaluated the scar satisfaction among patients and surgeons following COT using the Patient and Observer Scar Assessment Scale (POSAS) and the Patient Scar Assessment Questionnaire (PSAQ). A total of 116 patients were included. The median age of the patients was 44years and the majority were women. The median scar length overall was 12.2cm. On POSAS, the median score for surgeon 1 was 1 (range 1-5), for surgeon 2, it was 2 (range 1-6), and for the patient, it was 1 (range 1-6) suggesting good scar satisfaction. The patient's response in the PSAQ was also echoing similar outcomes with scar satisfaction. Overall, both the patients and the surgeons seem to be satisfied with the overall scar appearance following COT despite the scar length.

Quantitative comparison of three thyroidectomy approaches on neck muscles, voice, and swallowing functions

ObjectiveThis study compares endoscopic thyroidectomy by gasless unilateral axillary approach (ETGUA) and sternocleidomastoid leading-edge approach (SLEA) with conventional open thyroidectomy (COT) in hemithyroidectomy. The main focus is on the protection of neck muscles (sternocleidomastoid, omohyoid, sternothyroid) and the postoperative function of voice and swallowing yielded through these common approaches. MethodsA total of 302 patients who underwent hemithyroidectomy were enrolled and divided into three groups: ETGUA (n = 101), SLEA (n = 100), and COT (n = 101). Ultrasound was used to measure the thickness of bilateral neck muscles, including the sternocleidomastoid, omohyoid, and sternothyroid. The changes in thickness on the surgical side compared to the non-surgical side. Analyzed factors included muscle thickness changes, Swallowing Impairment Score (SIS), Voice Handicap Index (VHI), Scar Cosmesis Assessment and Rating (SCAR), Neck Incision Index (NII), surgery duration, drainage volume, hospitalization, and number of lymph nodes. ResultsThe clinical characteristics among the three groups were consistent except for differences in sex, age, and BMI. Metrics such as sternocleidomastoid muscle, NII, hypocalcemia, postoperative PTH, transient hoarseness, and number of lymph nodes showed no significant differences among the three groups. However, significant differences were found in the duration of surgery, drainage volume, hospitalization period omohyoid muscle, Sternohyoid muscle, VHI, SIS, and SCAR (all p < 0.001). ConclusionIn comparison to COT, ETGUA and SLEA demonstrate superiority in protecting neck muscles and preserving voice and swallowing function without compromising surgical safety or radicality.

Comparison of Surgical Outcomes of Transoral Versus Open Thyroidectomy for Graves Disease.

The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a safe alternative to thyroidectomy for thyroid goiter and provides the benefit of being scarless. However, the data on the use of TOETVA in patients with Graves disease are limited. This retrospective study compared the outcomes of Graves disease patients who underwent TOETVA versus those who underwent open thyroidectomy (OT). Patients with Graves disease who received TOETVA or OT for bilateral total thyroidectomy between September 2017 and October 2022 were included. Patient demographics and surgical outcomes, including operation time, blood loss, length of stay, and complications, were compared. There were 15 patients in each group. The mean age in the TOETVA group was 35.80±8.13 years, which was significantly younger than that in the OT group, which was 51.53±14.22 years. Females predominated in both groups. The other demographic characteristics were similar in both groups. The operation time and intraoperative blood loss were also comparable. The postoperative stay and complications, including hypoparathyroidism, recurrent laryngeal nerve injury, surgical site infection, postoperative hemorrhage, and recurrence of hyperthyroidism, were not different between the 2 groups. There were 11 patients in the TOETVA group and 10 in the OT group who had thyroglobulin levels <0.1ng/dL, indicating the completeness of total thyroidectomy in the 2 groups. There was no conversion of TOETVA to an open procedure. For carefully selected Graves patients, TOETVA offers a safe, scarless, and feasible alternative to conventional open thyroidectomy.

Comparison of Robotic Versus Conventional Open Thyroidectomy for Recurrent Laryngeal Nerve Safety: A Systematic Review and Meta-Analysis.

This review aims to investigate the safety of recurrent laryngeal nerve (RLN) by comparing robotic thyroidectomy (RT) versus open thyroidectomy (OT) in Western and Asian populations. Two main outcomes of this review were (1) the safety of RLN comparing the robotic and OT assessingtransient and permanentlaryngeal nerve (PLN) palsy as a postoperative complication in each surgical procedureand (2)the safety of RLN comparing the robotic and OT assessingtransient and permanentlaryngeal nerve (PLN) palsy as a postoperative complication between studies conducted in USA/Europe andAsia.We searched relevant literature in electronic databases such as PubMed, MEDLINE, Cochrane CENTRAL, ScienceDirect, and Cumulative Index to Nursing & Allied Health(CINAHL)up to September 2022. Furtherresearch was performed duringJanuary 2024 in the Scopus database. Two primary outcomes were set:transient RLN palsyand permanent RLN palsy, comparing RT and OT. In this review, 18non-randomized studies were included. A statistically significant difference between robotic and conventional OT was not observed either in transient RLN or in permanent RLN palsy. The odds ratio (OR) for the overall comparison of transient RLN palsy was 1.18, and the 95% confidence interval (95% CI) was 0.80-1.74. The subgroup analysis for transient RLN palsy between USA/Europe studies was OR 1.28, and the95% CIwas 0.64-2.58. The subgroup analysis for transient RLN palsy between Asian studies was OR 1.14, and the 95%CIwas 0.72-1.82. The OR for the overall comparison of permanentRLN palsy was OR 0.90, and the 95% CIwas 0.38-2.15. The subgroup analysis for permanentRLN palsy between USA/Europe studies was OR0.45, and the 95% CIwas 0.07-2.97. The subgroup analysis for permanentRLN palsy between Asian studies was OR1.13, and the 95% CIwas 0.42-3.05. Heterogeneity I2was 0% in all outcomes. The Mantel-Haenszel method fixed effect was used.First, RT and open conventional thyroidectomy have comparable safety for RLN, although the analysis showed no statistically significant results. Second, no statistically significant results were found for RLN safety in either USA/Europe or Asian studies.Considering that there is not a statistically significant difference between the two approaches for RLN safety, and due to the limited number of studies from Western countries, the results should be considered with caution. Important factors such as the patient's body characteristics, the existing thyroid pathology, and the surgical approachshould be kept in mind. More comparable studies are needed on the Western population.

Transoral endoscopic thyroidectomy vestibular approach versus conventional open thyroidectomy for the treatment of benign thyroid tumours: A prospective cohort study.

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). 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. 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). 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.

Surgical outcomes of endoscopic thyroidectomy approaches for thyroid cancer: a systematic review and network meta-analysis.

This network meta-analysis assesses the outcomes of seven endoscopic approaches, offering valuable insights for researchers and practitioners in choosing the best method for thyroid cancer patients. A systematic literature search was conducted in the PubMed, Embase and Web of Science databases up to March 2023. The analysis included seven endoscopic approaches, with a focus on their respective outcomes through network meta-analysis. This meta-analysis included 44 studies involving 8,672 patients. The axillo-bilateral breast approach (ABBA) and unilateral axillo-breast approach (UABA) showed advantages in terms of reduced operative time compared to other approaches (MD = 19.66 minutes, 95% CI = -31.66 to 70.98; MD = 30.32 minutes, 95% CI = -1.45 to 62.09, respectively). The UABA and anterior chest approach (ACA) exhibited superiority in controlling intraoperative bleeding (MD = -3.37 mL, 95% CI = -22.58 to 15.85; MD = -13.77 mL, 95% CI = -28.85 1.31, respectively). UABA and ACA also showed advantages in reducing hospital stays (MD = -0.39 days, 95% CI = -1.48 to 0.71; MD = -0.26 days, 95% CI = -1.33 to 0.81, respectively). The transoral approach (OA) yielded results comparable to those of conventional open thyroidectomy (COT) and outperformed other endoscopic surgeries with regards to lymph node retrieval and metastatic lymph node assessment. For the stimulated serum thyroglobulin (TG) levels, no significant difference was observed between bilateral axillo-breast approach (BABA) and OA compared to COT. However, chest-breast approach (CBA) showed significantly lower levels than COT (MD=-0.40 ng/ml, 95% CI =-0.72 to -0.09). Patients in the gasless unilateral transaxillary approach (GUA) group experienced a significant improvement in cosmetic satisfaction (MD=-2.08, 95% CI =-3.35 to -0.82). Importantly, no significant difference was observed in the incidence of surgical complications between endoscopic thyroidectomy andCOT. Endoscopic thyroid surgery is a safe and effective choice for thyroid cancer patients. Different approaches have their advantages, allowing personalized selection based on the patient's needs. ABBA and UABA have shorter operative times, while UABA and ACA excel at controlling bleeding and shortening hospital stays. OA shows promise for lymph node assessment. These findings contribute to the growing evidence supporting endoscopic methods, expanding treatment options for thyroid cancer patients.

Comparison of transoral endoscopic thyroidectomy vestibular approach and open conventional thyroidectomy regardıng inflammatory responses, pain, and patient satisfaction: a prospective study.

The application of transoral endoscopic thyroidectomy vestibular approach (TOETVA) is becoming widespread throughout the world. We primarily aimed to evaluate the severity of surgical trauma in TOETVA and conventional open thyroidectomy (COT) regarding the inflammatory response including the comparison of surgical stress markers [interleukin-6 (IL-6), C-reactive protein (CRP), white blood cell (WBC)]. This non-randomized prospective study enrolled two groups with 20 patients each: COT group and TOETVA group. Patients aged 18-65 years with benign thyroid disease; with fine needle aspiration biopsy results of Bethesda III, IV or Bethesda V, VI (<1 cm nodule); thyroid volume <50 cm3; nodule diameter <4 cm; female gender without a previous neck, chin, and/or oral surgery; without vocal cord paralysis preoperatively; and patients in euthyroid state were enrolled to the study. Preoperative, postoperative second hour, first day, and second day CRP, WBC, and IL-6 levels were evaluated. Pain intensity was evaluated with the visual analog scale (VAS) score on the 2nd and 12th hour, 1st and 2nd days postoperatively. All the patients were female and mean age was significantly higher in the COT group. The operative time was significantly longer in the TOETVA group. No significant difference was found between the two groups regarding IL-6 levels. In the TOETVA group, postoperative second hour WBC value (p = 0.044) and first (p = 0.002) and second day (p = 0.005) CRP values were significantly higher. In the TOETVA group, the lower lip and lower chin VAS scores were significantly higher at 2nd and 12th hour, on the first and second days. The anterior neck VAS score was significantly higher in the TOETVA group at the second hour (p = 0.025). General and cosmetic satisfactions were similar at the 15th and 30th days in both groups. The longer operative time and higher postoperative CRP level and VAS score in the chin and lower lip in the TOETVA group suggested that the method is not a minimally invasive technique compared to COT. However, the presence of similar total complication rates and early postoperative general and esthetic satisfaction that improves over time in both groups suggests that the clinical effect of increased magnitude of systemic inflammatory response in TOETVA might be temporary and acceptable.

Comparison of endoscopic bilateral areolar and robotic-assisted bilateral axillo-breast approach thyroidectomy in differentiated thyroid carcinoma: a propensity-matched retrospective cohort study

BackgroundRobot-assisted and endoscopic thyroidectomy are superior to conventional open thyroidectomy in improving cosmetic outcomes and postoperative quality of life. The procedure of these thyroidectomies was similar in terms of surgical view, feasibility, and invasiveness. However, it remains uncertain whether the robotic-assisted bilateral axilla-breast approach (BABA) was superior to the endoscopic bilateral areolar approach (BAA) thyroidectomy. This study aimed to investigate the clinical benefit of these two surgical procedures to evaluate the difference between these two surgical procedures by comparing the pathological and surgical outcomes of endoscopic BAA and robotic-assisted BABA thyroidectomy in differentiated thyroid carcinoma.MethodsFrom November 2018 to September 2021, 278 patients with differentiated thyroid carcinoma underwent BABA robot-assisted, and 49 underwent BAA approach endoscopic thyroidectomy. Of these patients, we analyzed 42 and 135 patients of endoscopic and robotic matched pairs using 1:4 propensity score matching and retrospective cohort study methods. These two groups were retrospectively compared by surgical outcomes, clinicopathological characteristics, and postoperative complications.ResultsThe mean operation time was significantly longer in the EG than in the RG (p < 0.001), The number of retrieved lymph nodes was significantly lower in the ET group than in the RT group (p < 0.001). The mean maximum diameter of the thyroid was more expansive in the EG than in the RG (p = 0.04). There were no significant differences in the total drainage amount and drain insertion days between the two groups (p = 0.241, p = 0.316, respectively). Both groups showed that cosmetic satisfaction (p = 0.837) and pain score (p = 0.077) were similar. There were no significant differences in complication frequencies.ConclusionRobotic and endoscopic thyroidectomy are similar minimally invasive thyroid surgeries, each with its advantages, both of which can achieve the expected surgical outcomes.Trial registrationRetrospectively registered.

A propensity score matching analysis of gasless endoscopic transaxillary thyroidectomy with five-settlement technique versus conventional open thyroidectomy in patients with papillary thyroid microcarcinoma.

In a previous study, we proposed a novel anatomy-based five-settlement method for transaxillary endoscopic thyroidectomy (fs-TAT) for patients with papillary thyroid carcinoma. The safety of this new method has been reported in a retrospective study of a single cohort. The safety and short-term oncological outcome of this method was confirmed by comparing it with conventional open surgery (COT) in patients with papillary thyroid microcarcinoma. The medical records of patients who underwent fs-TAT or COT by a single surgeon from February 2019 to December 2021 were reviewed retrospectively. All patients were diagnosed with papillary thyroid microcarcinoma and underwent lobectomy and ipsilateral central compartment neck dissection. Propensity score matching was used to compare the technical safety and short-term oncologic outcomes of fs-TAT and COT for the purpose of reducing potential selection bias. Reporting was consistent with the STROCSS 2021 guidelines. After propensity score matching, 460 (fs-TAT: 230; COT: 230) patients remained in the study population. There were no significant differences in sex, age, tumor size, Hashimoto's thyroiditis, or tumor multifocality between the groups. The operative time was longer [104.5 (90.3, 120.0) vs. 62.0 (52.0, 76.0), P < 0.001] and the total postoperative drainage volume [135(90, 210) vs. 75 (55, 115), P < 0.001] was greater in the fs-TAT group than in the COT group. However, intraoperative bleeding [3.0 (2.0, 5.0) vs. 5.0 (5.0, 7.5), P < 0.001] was greater, and the median number of lymph nodes yielded [5.0 (2.3, 8.0) vs. 7.0 (5.0, 11.0), P < 0.001] was greater in the COT group than in the fs-TAT group. The groups exhibited no significant difference in the rate of complications (fs-TAT: 2.2% vs. COT: 2.6%, P = 0.856), rate of positive lymph nodes (fs-TAT: 32.2% vs. COT: 36.5%, P = 0.377), length of postoperative hospital stay (3days vs. 3days, P = 0.305) or total medical costs (26,936 vs. 26,549, P = 0.144). Compared to conventional open surgery, fs-TAT offered excellent safety and acceptable short-term oncological outcomes in a selected cohort of patients with papillary thyroid microcarcinoma.

Safety and Efficacy of Transoral Endoscopic Thyroidectomy Vestibular Approach Versus Conventional Open Thyroidectomy: A Systematic Review and Meta-analysis.

To evaluate the safety and efficacy of the transoral endoscopic thyroidectomy vestibular approach (TOETVA) versus conventional open thyroidectomy (COT) for some thyroid diseases. Databases PubMed, Embase, and Web of Science were searched. Full-text English papers that described TOETVA and COT for people with thyroid diseases were included. Randomized, nonrandomized, controlled, and uncontrolled trials were all included. Extracted data included population characteristics and intraoperative and postoperative complications. A total of 2 randomized controlled trials and 10 retrospective studies, including 3048 patients, were included in the meta-analysis. Meta-analysis results suggested that the intraoperative conditions and postoperative complication rates did not differ significantly between the two groups. However, in the TOETVA group, there is a slightly longer operative time [weighted mean difference (WMD): 73.64; 95% CI: 49.34 to 97.94; P < 0.0001], drainage (WMD: 91.0; 95% CI: 35.52 to 146.48; P = 0.001), and hospital stay (WMD: 0.28; 95% CI: 0.18 to 0.38; P < 0.0001). For most of the benign thyroid nodules and selected patients with papillary thyroid cancer, TOETVA seems to be as feasible and safe as COT.

Endoscopic thyroidectomy using the axillo-breast approach in patients with lactating and/or large ptotic breasts

IntroductionThe purpose of this study is to evaluate the outcomes of endoscopic hemithyroidectomy (EH) performed via the modified unilateral axillo-breast approach (UABA) in patients with lactating and/or large ptotic breasts. MethodsBetween 2019 and 2021, we studied the records of twenty-three eligible female patients with lactating and/or large ptotic breasts who were presented with benign unilateral thyroid nodule (s) and who were treated by EH using modified UABA at Mansoura University Oncology Center or Meet Ghamr oncology center. The demographic data, clinicopathological parameters, operative and the esthetic outcomes were collected and analyzed. ResultsNine patients (39%) were lactating. All patients were obese (the mean BMI was 37.82 ± 4.37). All patients were having large breasts, cup C and D sizes (34% of patients & 56% of patients respectively), except for only two lactating female patients who had Cup B breasts. All patients were having ptotic breasts. The thyroid nodules greatest dimension ranged from 2.1–6 cm. All procedures were completed successfully endoscopically without any perioperative adverse events except for one case with temporary hoarseness of voice and three cases with axillary port sites cellulitis. The mean operative time was 83.26 ± 7.92 min. The patient satisfaction scores were high. ConclusionEH via modified UABA in patients with lactating and/or large ptotic breasts is safe, feasible and effective procedure without adverse events. It should be offered to this group of patients as an alternative to conventional open thyroidectomy if there is no other contraindication.

Endoscopic Thyroidectomy: A 6-Year Experience from a Tertiary Care Teaching Hospital in Western India.

Background: Minimally invasive and endoscopic surgical techniques have surpassed the conventional open thyroidectomy for the treatment of thyroid nodules. Trans-axillary, Unilateral Axillo-Breast Approach (UABA), Bilateral Axillo-Breast Approach, and Trans-Oral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) are the most common endoscopic procedures performed currently. This article highlights our experiences with UABA and TOETVA over a period of 6 years. Materials and Methods: Between January 2015 and December 2020, we retrospectively analyzed our experience in Endoscopic thyroidectomy with 119 patients using UABA (n = 72) and TOETVA (n = 47) in our tertiary care teaching hospital. Both approaches used the standard three-port technique. Real time angiography was performed intraoperatively using Indocyanine Green dye to delineate the vessels in all patients. Results: The mean operative time for UABA and TOETVA was 90 and 110 minutes, respectively. Estimated blood loss was 18 mL in the former and 20 mL in the latter. Temporary Recurrent Laryngeal Nerve palsy and Hypoparathyroidism were minimal with TOETVA (5 patients versus 4 patients and 7 patients versus 2 patients). Shorter duration of hospital stay was observed with UABA (3 days versus 5 days). Cosmetic satisfaction was better with TOETVA. Conclusion: Based on our 6-year experience, we propose "JJ Hospital Criteria," which we currently follow to decide which surgical approach will yield best results. UABA and TOETVA are safe, feasible, and give exceptional cosmetic satisfaction. Both approaches should be seen as complementary rather than competitive.

Comparison of surgical completeness in patients operated on conventional open total thyroidectomy (OT) or trans-axillary robot-assisted total thyroidectomy (RATT) by a single axillary approach.

Trans-axillary robot-assisted total thyroidectomy (RATT) is nowadays worldwide accepted but the completeness obtained by RATT is still debated. The Aim of this study was to compare the completeness and safety of RATT with conventional open thyroidectomy (OT). We enrolled patients with nontoxic multinodular goiter, cytologically indeterminate nodules and well differentiated thyroid cancer without local and/or distant metastasis. In all cases the biggest nodule should be < 6cm. The surgical completeness was evaluated by means of serum thyroglobulin (hs-Tg) and neck ultrasound (nUS) performed three months postoperatively. 100 patients underwent either RATT or OT. The type of surgical procedure was chosen by patients. They were then divided in two subgroups based on benign or malignant histology. There were no significant differences in the postoperatively values of hs-Tg in patients operated with RATT or OT, both in benign and malignant subgroups. The post-operative thyroid remnant volume estimated by nUS was not significantly different between the two groups, both in benign and malignant subgroups. We also analyzed the difference of the volume of the thyroid remnant ipsilateral to the axillary access vs that of the remnant on the contralateral side and there was not significantly difference in both subgroups. RATT was demonstrated to determine a comparable surgical completeness as OT, both in benign and malignant thyroid diseases, with no differences in the prevalence of surgical complications. In our hands the surgical completeness of RATT by a single trans-axillary was satisfying.

The necessity of resection of suprasternal fossa fat in total endoscopic thyroidectomy via the areola approach.

The identification of a lower boundary for the central lymph node (CLN) of the neck in total endoscopic thyroidectomy via the areola approach (ETA) is important for its radical dissection. We found that resection of the suprasternal fossa fat (SFF) was beneficial for exposing the lower boundary and preventing suprasternal swelling after the operation. This retrospective analysis included 470 papillary thyroid carcinoma (PTC) cases, with some treated by unilateral lobectomy, some by central lymph node dissection (CLND) through ETA (n = 193), and the others by conventional open thyroidectomy (COT, n = 277). The main observation indicators included the total number of CLNs, CLND operative time, visualization of the upper pole of the thymus before removing the CLN, and postoperative suprasternal swelling. The SFF retention group and COT group had a similar percentage of women (78.65% vs. 79.42%, P = 0.876) lower than that in the SFF resection group (95.19%, P < 0.001). The percentage of the visualized upper pole of the thymus before CLN removal was notably higher in the SFF resection group than that in the SFF retention group (63.46 vs. 29.21%, P < 0.001) but notably lower than that in the COT group (63.46% vs. 100%, P < 0.001). A total of 43.82% and 23.1% of patients in the SFF retention and COT groups showed suprasternal swelling, respectively. No patient exhibited such swelling in the SFF resection group (23.1% vs. 0, P < 0.001). Resection of SFF in ETA easily identified the lower boundary for CLND and prevented suprasternal fossa swelling.

Single-port endoscopy-assisted thyroidectomy via cervical gas-insufflation approach for papillary thyroid carcinoma: A pilot retrospective comparative study

PurposeThis study aims to investigate the safety and efficacy of our novel technique of single-port endoscopy-assisted thyroidectomy via cervical gas-insufflation approach (SPEAT, also called the Huang procedure) in the treatment of papillary thyroid carcinoma (PTC). Materials and methodsWe perform a retrospective comparative study from a prospectively maintained database. A cohort of 82 patients with PTC who underwent total thyroidectomy and central neck dissection were included. Of these patients, 48 underwent SPEAT and 34 underwent conventional open thyroidectomy (COT). The differences in surgical outcome and oncological completeness were compared. ResultsCompared with the COT group, the SPEAT group had obviously shorter incision (P < 0.001), less postoperative pain (P = 0.036), better cosmetic satisfaction (P = 0.001)and slightly longer operating time (P = 0.041). In intraoperative bleeding, postoperative drainage, postoperative hospital stay, surgical complications, number of dissected or positive lymph nodes per patient, and postoperative non-stimulated or stimulated thyroglobulin levels, there were no significant differences. ConclusionsSPEAT (the Huang procedure) is a minimally invasive, safe and oncologically complete surgical option for PTC in selected patients.

Clinical efficacy and inflammatory reaction of submental endoscopic thyroidectomy versus conventional thyroidectomy: A prospective randomized study

ObjectivesThis prospective study aimed to explore the clinical efficacy and inflammatory reaction of submental endoscopic thyroidectomy versus conventional thyroidectomy. MethodsWe prospectively recruited 45 patients (total 90 patients) who met the eligibility criteria to undergo conventional open thyroidectomy or submental endoscopic thyroidectomy from January 2021 to July 2022 in the Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. These patients were evaluated using the following indices: number of lymph nodes dissected, complications, pain severity, inflammatory indicators, cosmetic satisfaction, and economic cost. All data were analyzed by the t-test or chi-squared test. ResultsNinety patients were enrolled. The two groups did not significantly differ regarding baseline characteristics. All patients who underwent thyroidectomy had a similar trauma index and increased level of inflammation. There were no significant differences between the open thyroidectomy and submental endoscopic thyroidectomy groups in the total number of lymph nodes dissected, number of positive lymph nodes, drainage volume, and complications. The Vancouver scar score and cosmetic satisfaction score were significantly better in the submental endoscopic thyroidectomy group than the open thyroidectomy group. The submental endoscopic thyroidectomy group had a significantly lower pain scores on postoperative days 1 and 2, less downtime, and cheaper medical and esthetic costs than the open thyroidectomy group. ConclusionCompared with conventional open thyroidectomy, submental endoscopic thyroidectomy did not increase the degree of trauma, had superior clinical efficacy, caused less pain, required a shorter downtime, achieved a better cosmetic effect, and was associated with lower healthcare costs.

Transoral thyroidectomy vestibular approach vs. conventional open thyroidectomy: a systematic review and meta-analysis.

The purpose of this study was to compare the intraoperative outcomes and postoperative complications of patients experiencing transoral thyroidectomy vestibular approach (TOTVA) and conventional open thyroidectomy (COT). PUBMED, EMBASE, the Cochrane Central Register of Controlled Trials in the Cochrane Library, and Web of science expanded between January 2007 and November 2022 comparing TOTVA and COT was exhaustively searched. Fifteen non-randomized controlled studies involving 2955 patients were included. The results of meta-analyses indicated that TOTVA was associated with longer operative time (WMD, 66.86; 95%CI, 47.15-86.56; P < 0.00001), more blood loss (WMD, 2.83; 95%CI, 1.77-3.90; P < 0.00001), higher incidence of wound infection (OR, 5.62; 95%CI, 1.57-20.10, P = 0.008). There was no significant difference in terms of transient recurrent laryngeal nerve (RLN) palsy and other postoperative outcomes. In conclusion, TOTVA appears to be a feasible and safe approach for the treatment of patients with benign thyroid nodules and selected differential thyroid carcinomas just like the COT.

Endoscopic thyroidectomy via areola approach for stage T1 papillary thyroid carcinoma: feasibility, safety, and oncologic outcomes.

To evaluate the feasibility, safety, and oncologic outcomes associated with endoscopic thyroidectomy via the areolar approach (ETAA), compared with conventional open thyroidectomy (COT) for the treatment of stage T1 papillary thyroid carcinoma (PTC). Between January 2021 and June 2022, a total of 1204 patients diagnosed with PTC underwent screening, out of which 138 patients were selected for inclusion in the study population after propensity score matching (92 patients in the ETAA group and 46 patients in the COT group). The study included the collection and analysis of clinicopathologic characteristics, intraoperative outcomes, postoperative outcomes, complications, and follow-up data using R software. The operative time for the ETAA group was longer than that for the COT group (160.42 ± 32.21 min vs. 121.93 ± 29.78 min, p < 0.0001). However, there were no significant differences between the two groups in terms of intraoperative blood loss, the extent of surgical resection, the number of dissected lymph nodes, the number of metastatic lymph nodes, and the rate of parathyroid autotransplantation. Postoperative drainage and C-reactive protein levels were higher in the ETAA group than in the COT group, but there were no significant differences in 24-hour visual analogue scale scores, white blood cell counts, drainage duration, or postoperative hospital stay. Complication rates were similar between the two groups, and no permanent recurrent laryngeal nerve palsy or hypoparathyroidism was observed. Patients who underwent ETAA reported greater cosmetic satisfaction and quality of life than those who underwent COT. During the follow-up phase, only one patient in the COT group developed lateral cervical lymph node involvement requiring reoperation. ETAA is a safe and feasible surgical method for patients with stage T1 PTC, providing results similar to COT in terms of oncologic completeness, while avoiding neck scars, with excellent cosmetic effects.

Comparison of endoscopic thyroidectomy by complete areola approach and conventional open surgery in the treatment of differentiated thyroid carcinoma: Aretrospective study and meta-analysis.

The feasibility of endoscopic thyroidectomy by complete areola approach (ETCA) remains controversial. This study was conducted by combining our clinical data with the data obtained from a systematic review literature search to examine the effectiveness and safety of ETCA compared with conventional open thyroidectomy (COT) in differentiated thyroid carcinoma (DTC). A total of 136 patients with a diagnosis of DTC who underwent unilateral thyroidectomy with central neck dissection from August 2020 to June 2021 were enrolled. The enrolled patients were divided into the ETCA group (n = 73) and the COT group (n = 63). The operative time, intraoperative bleeding volume, number of removed lymph nodes, number of metastatic lymph nodes, postoperative drainage volume, length of postoperative hospital stay, postoperative parathyroid hormone (PTH) levels, and complications were analyzed. Then, a systemic review and comprehensive literature search were conducted by using PubMed, Google Scholar, Embase, Web of Science, CNKI, Wanfang, and VIP database up to June 2022. Review Manager software version 5.3 was used for the meta-analysis. The results of clinical data showed that there were significant differences between the two groups in the operative time, intraoperative bleeding volume, removed lymph nodes, and postoperative drainage volume. There were no statistical differences in the length of postoperative hospital stay, number of metastatic lymph nodes, postoperative PTH level, and complications. In the systematic review and meta-analysis, 2,153 patients from fourteen studies (including our data) were ultimately included. The results of the meta-analysis found that ETCA had a longer operative time, larger postoperative drainage volume, and lower intraoperative bleeding volume. In terms of the length of postoperative hospital stay, the number of removed lymph nodes, and surgical complications, there was no significant difference between the two groups. ETCA poses lower surgical bleeding and better cosmetic appearance compared with COT, while the length of operation and postoperative drainage in ETCA is less favorable compared with COT. In addition, ETCA is not inferior to COT in terms of the postoperative hospitalization stay, the number of removed lymph nodes, and surgical complications. Given its overall advantages and risks, ETCA is an effective and safe alternative for patients with cosmetic concerns.
