RESUMO
Objective:To investigate the effect of endoscopic thyroidectomy through breast milk approach in patients with papillary thyroid carcinoma and its influence on Wnt and integrin signaling pathways.Methods:A total of 136 patients diagnosed with papillary thyroid carcinoma in our hospital from Jul. 2018 to Mar. 2020 were selected and were hospitalized for surgical treatment. According to different surgical procedures, they were divided into a study group (68 cases) and a control group (68 cases) . The control group was treated with open thyroidectomy and the study group was treated with thoracoscopic thyroidectomy. The two groups were compared in terms of immune function [CD4+, CD8+ and CD4+/CD8+], and pain index [PGE2, IL-6, Cor and VAS score]. RT-PCR method was used to detect WNT1, β-catenin, GSK3β and integrin Signal pathway before and after surgery.Results:Three days after operation, compared with the control group, the study group had significantly higher CD4+ and CD4+/CD8+ levels [ (27.62±2.52) vs (24.63±2.67) , (0.66±0.18) vs (0.52±0.13) ], while the CD8+ level was significantly lower [ (41.62±3.54) vs (45.62±3.63) ] ( P<0.001) ; PGE2, IL-6, Cor, VAS of the study group were significantly lower than the control group [ (48.54±9.86) vs (57.21±8.12) , (5.13±0.71) vs (6.99±0.95) , (511.23±67.52) vs (633.12±71.47) , (1.26±0.56) vs (3.99±2.06) ] ( P<0.001) ; WNT1, β-catenin, GSK3β, integrin β1, FAK, Ras, and MAPK mRNA expression levels in the study group were significantly lower than those of the control group[ (1.79±0.15) vs (2.85±0.25) , (1.94±0.15) vs (2.64±0.24) , (2.13±0.19) vs (2.97±0.28) , (1.95±0.17) vs (2.58± 0.23) , (2.15±0.16) vs (2.87±0.22) , (1.95±0.18) vs (2.91±0.27) , (1.89±0.12) vs (2.87±0.31) ] ( P<0.001) . Conclusion:Endoscopic thyroidectomy through thoracolumbar approach can effectively reduce postoperative pain in patients with papillary thyroid cancer, have a smaller impact on immune function, and block the expression of Wnt and integrin signaling pathways to reduce tumor metastasis risk.
RESUMO
BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate surgical completeness in endoscopic total thyroidectomy with central neck dissection via unilateral axillo-breast approach (UABA) compared with bilateral axillo-breast (BABA) and open approach (OA) by means of the radioactive iodine uptake (RAIU) ratio and thyroglobulin (Tg) of remnant thyroid. SUBJECTS AND METHOD: From July 2010 to March 2013, 82 patients who had underwent total thyroidectomy with central neck dissection and postoperative radioactive iodine (RAI) ablation for papillary thyroid carcinoma were enrolled. Of these patients, 27 patients underwent UABA, 24 patients BABA, and 31 patients OA. Clinicopathologic data, surgical outcome, stimulated Tg and RAIU ratio on the first postoperative RAI ablation scan were compared among 3 groups. RESULTS: Patients in the endoscopic surgery groups (UABA, BABA) were younger than those in the OA groups. Invasiveness such as operation time, postoperative pain, and drain amount in UABA was less than that in BABA and severer than that in OA. Other variables regarding clinicopathologic and surgical data were not significantly different. Stimulated Tg and RAIU ratio did not show significant differences among 3 groups (p=0.659 and p=0.664). CONCLUSION: The completeness of UABA was comparable with that of BABA and OA. The UABA may be a safe option for patients who need endoscopic thyroidectomy for papillary thyroid carcinoma.

Objective To compare the surgical effect of gasless endoscopic thyroidectomy and CO2- insufflation endoscopic thyroidectomy, and evaluate the safety and applicability of gasless endoscopic thyroidectomy. Methods A prospective randomized controlled study was carried out.Sixty patients who were scheduled for bilateral thyroid surgery under endoscope were divided into 2 groups by sortition method: gasless group (30 patients, treated with gasless endoscopic thyroidectomy) and CO2-insufflation group (30 patients, treated with CO2-insufflation endoscopic thyroidectomy). The data of arterial partial pressure of carbon dioxide (PaCO2) and pH value before operation and 60 min after operation were detected. The operation time, intraoperative bleeding, time of putting the drain, hospitalization time after operation and postoperative complications were recorded. Results All the 60 patients completed endoscopic surgery,and no case was converted to the conventional procedure.There were no statistical differences in PaCO2and pH value before operation between 2 groups(P>0.05).The PaCO260 min after beginning of operation in gasless group was significantly lower than that in CO2-insufflation group:(36.43 ± 1.98)mmHg(1 mmHg=0.133 kPa)vs.(37.93 ± 3.27)mmHg,the pH value 60 min after beginning of operation was significantly higher than that in CO2-insufflation group:7.42 ± 0.02 vs. 7.37 ± 0.01, and there were statistical differences (P<0.05 or <0.01). There were no statistical difference in operation time, intraoperative bleeding, time of putting the drain, hospitalization time after operation and incidence of hoarseness between 2 groups (P>0.05). There were no complications related with trachea, parathyroid gland and superior laryngeal nerve in 2 groups. The incidence of CO2retention related complications in gasless group was significantly lower than that in CO2-insufflation group: 6.7% (2/30) vs. 43.3% (13/30), and there was statistical difference (P<0.01). Conclusions The modified spring suspension gasless endoscopic thyroidectomy not only acquires the equivalent surgical effect and indication,compared with the CO2-insufflation endoscopic surgery,but also is safer and has lower incidence rate of CO2retention related complications.
RESUMO
Objective To explore the technique and significance of intraoperative neuromonitoring (IONM) for scarless in the neck endoscopic thyroidectomy (SET) via breast approach.Methods From Apr.2015 to Oct.2015,101 consecutive patients undergoing SET with IONM were included.During the operation,patients received radical resection of the thyroid cancer by Wang's seven-step method.The lymph nodes in the central area were dissected and Wang's multi-functional separation forceps were implemented for recurrent laryngeal nerve (RLN) positioning,monitoring and protection.Also,time required for RLN positioning and exposure,postoperative transient and permanent RLN damage incidence were calculated to assess the feasibility of IONM under SET.Results Among 101 patients,130 RLNs in total were exposed.The average time required for RLN positioning under IONM was (3.26 ± 1.08)min,with round-nerve management time of (13.95 ± 4.58)min.Nerve signal change happened in 16.9％(22/130) patients.Positive predictive value was 13.6％ and negative predictive value was 100％.The overall accuracy rate was 85.4％.Conclusion IONM during SET is feasible,and can be helpful for the localization and functional protection of RLN and was useful to predict vocal cord paralysis.
RESUMO
Objective To study the application value of endoscopic thyroidectomy via total membrane dissection. Methods One hundred and sixteen patients with benign thyroid nodules were given axillo-breast approach endoscopic thyroidectomy via total membrane dissection from January 2014 to December 2016. Results Endoscopic thyroidectomy was completed in all the patients without conversion to open surgery.The operation time was 45-125 min[mean,(65.6 ±36.7)min],the blood loss was 10-220 ml[mean,(43.2 ±22.7)ml],the postoperative drainage volume was 25-305 ml[mean,(95.3 ±53.8)ml], the postoperative drainage time was 2-4 d[mean,(2.3 ±0.7)d)],and the length of hospital stay was 3-6 d[mean,(4.1 ±1.1)d].Short-term twitch occurred in 1 case and seroma occurred in 2 cases.No other complications such as hoarseness,bucking or asphyxia occurred in this series. Conclusion Endoscopic thyroidectomy via total membrane dissection can effectively avoid the injury of recurrent laryngeal nerve and parathyroid gland.
RESUMO
In the bilateral axillo-breast approach (BABA), the camera is inserted through the areolar incision, and this raises the concern it might be difficult to identify the lymph nodes (LN). The purpose of this study is to evaluate the feasibility of the Firefly for central lymph node dissection (CLND) in robotic thyroidectomy using the BABA. This study evaluated 18 patients who underwent robotic surgery using Firefly between December 2015 and March 2016. For LN mapping, 0.05 ml of ICG was injected into the thyroid 3~4 minutes before CLND. Green-stained LN could be detected easily through a near-infrared camera. The number of retrieved LNs was 7.8±3.0 after CLND using the Firefly, which was higher than the 6.7±0.2 reported in previous surgeries. In addition, it helped to distinguish between the parathyroid and the LNs. The Firefly technology was helpful in identifying the LNs, guiding the CLND and performing a complete CLND.

Objective To explore the clinical value of mini instruments in breast approach endoscopic thyroidectomy (BAET). Methods We retrospectively analyzed the data of 40 patients receiving BAET with mini instrument in our department of Changzheng Hospital from Sep. 2012 to Dec. 2013. The average age of patients was (33. 53 + 8. 76) years old and the tumor size was (21. 10 + 10. 96) mm. According to intraoperative frozen pathology, 19 cases underwent unilateral lobectomy, six cases underwent subtotal thyroidectomy, seven cases underwent total thyroidectomy, and eight cases underwent radical resection of thyroid carcinoma. Results Forty BAET procedures with mini instruments were completed successfully without conversion to open operation, and the complete tumor resection was achieved in all cases. The average operative time was (112. 25 + 31. 52) min in the patients, and the VAS-12 h, VAS-24 h, VAS-48 h and RSS (cosmetic score) were 2. 48 + 1. 13, 0. 85 + 0. 8, 0. 25 + 0. 44 and 8. 75 + 1. 26, respectively. Four patients had temporary hypocalcemia and one had recurrent laryngeal nerve paralysis after operation. Conclusion Application of mini instruments in BEAT can make endoscopic thyroidectomy less invasive and can improve the cosmetic results, without increasing the surgical difficulty and complications.
RESUMO
PURPOSE: Postoperative pain for robotic thyroid surgeries including bilateral axillo-breast approach (BABA) has not been well studied. In this study, we have developed a self-reporting application (SRA) for iPad and prospectively collected pain scores from open thyroidectomy (OT) and BABA robotic thyroidectomy (RT) patients. METHODS: Female patients who underwent total thyroidectomy for papillary thyroid carcinoma were included. Patients recorded pain scores for throat, anterior neck, posterior neck, chest, and back on postoperative days 1, 2, and 3. Once discharged, on postoperative day 14, a survey was also conducted on satisfaction of SRA and cosmesis. RESULTS: A total of 54 patients were enrolled (27 BABA RT and 27 OT). There were no significant differences between the 2 groups in clinicopathological characteristics and postoperative complication rates. Postoperative pain scores at days 1, 2, 3, and 14 were not significantly different between the groups for throat, anterior neck, posterior neck, or back. Postoperative analgesic requirements were similar between the 2 groups. Wound satisfaction scores were significantly higher in the BABA RT group (BABA RT 7.4 vs. OT 5.7; P = 0.016). Satisfaction scores for the usefulness of SRA were above 7.2 for all four questionnaire items on the 10-point scale. CONCLUSION: Postoperative pain for BABA RT is equivalent to OT but offers greater cosmetic satisfaction for patients. A mobile device application such as SRA may facilitate proper assessment and management of pain in postoperative patients.

PURPOSE: We investigated the efficacy and safety of endoscopic thyroidectomy using bilateral axillo-breast approach (BABA) by analyzing short term surgical outcomes. METHODS: We retrospectively evaluated 355 patients who underwent BABA endoscopic thyroidectomy between August 2006 and December 2011 at Chonnam National University Hospital and Hwasun Chonnam National University Hospital. The age, sex, clinical and pathologic characteristics of tumors, extent of operation, conversion rate to open thyroidectomy, operation time, hospital stay, thyroglobulin levels after thyroidectomy, recurrence, and complications were analyzed retrospectively. RESULTS: The mean age of the patients was 35 years. The 355 patients comprised 345 females (97.2%) and 10 males (2.8%). The benign tumor was 37 cases (10.4%) and the malignant tumor was 318 cases (89.6%). 28 patients (75.7%) of the benign tumor underwent lobectomy. In malignant tumor, 159 patients (50.0%) underwent lobectomy and 152 patients (47.8%) underwent total thyroidectomy. Mean operation time was 121.1+/-49.9 minutes, and mean hospital days were 3.4+/-1.1 days. 21 (6.0%) transient hypocalcemia and 7 (2.0%) permanent hypocalcemia were occurred. The transient voice change occurred in 5 patients (1.4%), but nobody suffered from the permanent recurrent laryngeal nerve injury. 4 patients of recurrent (1.3%) papillary thyroid carcinoma were treated by surgery. CONCLUSION: Compare to open thyroidectomy with long term follow up studies, BABA endoscopic thyroidectomy is a useful treatment option for both benign and malignant thyroid tumor.

PURPOSE: The aim of this study was to evaluate the safety of robotic or endoscopic thyroidectomy via bilateral axillo-breast approach (BABA) without a drainage procedure. METHODS: A total of 64 patients who underwent robotic or endoscopic thyroidectomy via BABA without a close suction drain between February and March 2012 were enrolled. We checked postoperative symptoms or signs including change of vital signs, dyspnea, swelling or fluctuation of anterior chest and neck and compression symptoms at 1, 6, 24, and 48 hours and 1 month after surgery. Postoperative ultrasonography was performed in patients with at least one or more postoperative symptoms or signs in order to confirm hematoma or fluid collection. RESULTS: None of the enrolled patients had dyspnea or change of vital signs. Two of 64 patients had swelling, 1 of 64 patients had fluctuation on the anterior chest, and 1 of 64 patients had compression symptoms. Fluid collection was confirmed in 2 of 4 of the above mentioned patients and the collected fluid was aspirated. The amounts of aspirated fluid were 25 mL and 8 mL. Thereafter, the follow up ultrasonography showed no more fluid collection in all patients. In addition, we rechecked the above mentioned symptoms or signs at 1 month after surgery; none of the enrolled patients had symptoms or signs. CONCLUSION: Robotic or endoscopic thyroidectomy via BABA without a closed suction drain shows no serious seroma or hematoma collection. Therefore, we expect that robotic or endoscopic thyroidectomy via BABA without a closed suction drain can reduce the pain, discomfort or longer hospital stay as a result of closed suction drain using this method.

Since the adoption of the Da Vinci robotic system for remote access thyroid surgery, robotic thyroidectomy (RT) has become a popular surgical option for patients who want to avoid neck scars. Surgeons in South Korea pioneered this surgical technique and have reported successful outcomes. Although many studies have reported that RT is a feasible and safe therapeutic alternative, concerns over the surgical and oncological safety of RT remain. This article reviews the advantages and disadvantages of RT and compares the surgical safety and oncological completeness of RT with conventional open thyroidectomy.

Cervical vagal schwannomas with cystic degeneration changes are extremely rare. These tumors are typically benign and slow growing. A 44-year-old woman underwent complete resection of a tumor measuring 4x3.5 cm in the right neck using the endoscopic approach, instead of the conventional transcervical approach. We applied the new scarless neck surgery technique with an endoscopic unilateral axillo-breast approach. The tumor originated from the right vagus nerve, and was confirmed to be a vagal schwannoma pathologically. The patient has been followed up for 18 months postoperatively with no evidence of tumor recurrence or neurological deficit. We report an extremely rare vagal schwannoma with cystic degeneration that was removed by an endoscopic approach, along with a review of the relevant literature.

PURPOSE: The aim of this study was to evaluate the operative feasibility and safety of endoscopic thyroidectomy via bilateral axillo breast approach (BABA) compared to conventional thyroidectomy in papillary thyroid carcinoma (PTC) patients. METHODS: From July 2009 to November 2010, patients underwent BABA endoscopic thyroidectomy (ET group; n=41) or conventional open thyroidectomy (OT group; n=61) for PTC. Clinical and pathologic characteristics of patients, operation time, post-operative complications, cosmetic satisfaction and thyroglobulin (TG) level were analyzed retrospectively. RESULTS: The mean age of the patients was 40.05±9.58 years (range 25~61 years) and 46.21±13.68 years (range 19~79 years) for the ET and OT group, respectively. The operative extent in the ET group did not include advanced thyroid cancer or lateral neck dissection. The size of the tumor was 0.78±0.59 cm (range 0.1~3.00 cm) and 1.54±1.05 cm (range 0.3~6.00 cm) for the ET and OT group, respectively. Extrathyroidal extension and number of retrieved lymph nodes were significantly higher in the OT group. Postoperative radioactive iodine ablation was performed on 25 patients (72.43%) in the ET group and 48 patients (78.69%) in the OT group. There was no abnormal uptake on radioactive iodine scans in the iodine-treated patients and no significant differences in postoperative off-T4 TG levels between the two groups. There were no significant differences in operative time, amount of drainage, postoperative hospitalization period, hypocalcemia, and vocal cord palsy between the two groups. Cosmetic results of ET group were rated as excellent in a 3-month postoperative questionnaire by 25 (72.43%) of 35 patients. CONCLUSION: Endoscopic thyroidectomy via the bilateral axillo breast approach can be a feasible and effective option for PTC in selected cases.

PURPOSE: Endoscopic thyroid surgery has been widely used because of the cosmetic advantage and the development of laparoscopic instruments. We have performed endoscopic thyroidectomy by breast approach and gasless transaxillary approach on papillary thyroid microcarcinomas. In this study, we describe these two types of endoscopic procedures with the technique of the method and surgical outcomes. METHODS: From Oct. 1999 to Oct. 2009, each procedure was performed in 162 patients divided into two groups. Breast approach group was in 91 patients and gasless transaxillary approach group was in 71 patients. We compared the results of mean ages, sex ratio, extent of operation, mean hospital stay, operating time, pathologic characteristics and postoperative complications between the breast approach group and gasless transaxillary approach group. RESULTS: Ninety-one cases treated using breast approach, and seventy-one cases treated using gasless transaxillary approach. The operation time was 197.4+/-60.7 minutes (95~350) in breast approach group, and 100.1+/-19.8 minutes (65~140) in gasless transaxillary approach group. Post operative complications are; 2 cases of transient hoarseness, 8 cases of hypocalcemia (including 2 cases of permanent hypocalcemia), 2 cases of chest wall discomfort in breast approach group, and 1 case of transient hoarseness, 2 cases of transient hypocalcemia, 1 case of postoperative bleeding in gasless axillary approach group. CONCLUSION: Endoscopic thyroidectomy is a safe and technically feasible alternative to conventional thyroidectomy in patients with benign and highly selected malignant disease. We expect it can increase the extent of surgery.

PURPOSE: A conventional thyroidectomy requires a wide transverse incision on the anterior neck, which can cause significant scaring. We developed an endoscopic thyroid lobectomy using the breast approach and a low carbon dioxide pressure in order to produce better cosmetic results. We reports the clinical analysis of endoscopic thyroid lobectomy and compare the result with those from a conventional thyroid lobectomy. METHOD: From July 2003 and December 2004, 55 consecutive patients with benign thyroid nodules, who underwent endoscopic thyroid lobectomy, and 51 consecutive patients with benign thyroid nodules, who underwent a conventional thyroid lobectomy, were retrospectively reviewed. The preoperative diagnosis of the thyroid nodules was performed using high-resolution ultrasonography and fine- needle aspiration cytology. The clinical results of endoscopic thyroid lobectomy were analyzed and compared with those from a conventional thyroid lobectomy. RESULTS: There were no significant differences between the two groups in terms of the patients' gender, size of tumor, preoperative diagnosis (follicular tumor/adenomatous nodule), postoperative diagnosis (cancer/benign), level of postoperative discomfort, length of hospital stay. The patients who underwent endoscopic thyroidectomy were significantly younger than those underwent conventional thryoidectomy (37.4+/-10.3 years vs. 48.8+/-13.0 years; P<0.001). The operation time for the endoscopic group was significantly longer than that for the conventional group (171.9+/-35.6 min vs. 92.5+/-26.5 min; P<0.001). The length of closed drainage in the endoscopic group was longer than that in the conventional group (2.8+/-0.8 days vs. 1.4+/-1.3 days; P<0.001). However, these factors did not affect the length of the hospital stay, and the number of intraoperative complications. CONCLUSION: Endoscopic thyroid lobectomy using the breast approach and a low carbon dioxide pressure has cosmetic benefits and is a feasible and safe procedure.

Objective To study the benefits and drawbacks of endoscopic thyroidectomy via breast approach by using gasless anterior neck skin lifting method.Methods A total of 21 patients with thyroid diseases were enrolled in this study,including 16 cases of nodular goiter and 5 cases of primary hyperthyroidism.All the cases underwent endoscopic subtotal thyroidectomy through breast approach while the operational space was established by using an abdomen suspending device and 2 Kirschner pins to mechanically suspend and retract the anterior neck skin.Results The endoscopic subtotal thyroidectomy was completed successfully in all of the cases without conversion to open surgery.The mean operation time was 82.5 minutes(ranging from 57 to 125 minutes).Intraoperative blood loss was less than 20 ml.Post-operational recovery was satisfying in all the patients.Drainage volume averaged 80.6 ml(50 to 150 ml).The patients were followed up for 1 to 12 months after the operation,during which no complications occurred.Conclusions Endoscopic thyroidectomy via breast approach using gasless anterior neck skin lifting method is a safe and low-cost procedure.By using the method,CO2 insufflation-related complications can be avoided.Although the operational space established by this method is relatively small,the operation can be completed without much difficulies.
RESUMO
PURPOSE: Neck surgery is one of the newest fields of endoscopic surgical application. We have developed a technique for performing endoscopic thyroidectomy using a breast approach and low-pressure CO2. We report this surgical procedure and its results. METHODS: One hundred patients underwent endoscopic thyroidectomy using a breast approach. Preoperative fine needle aspiration cytology revealed 74 benign nodules, 21 follicular neoplasms, 4 in which there was difficulty in distinguishing between benign and malignant tumor and 1 not checked. We used 3 incisions on both upper circumareolar areas and one at about 3 cm below the clavicle on the tumor side. Three trocars, 5 mm, 10 mm, 15 mm were used. Subplatysmal and subcutaneous operative space was created with CO2 insufflation at 6 mmHg of pressure. The thyroidal vessels and the parenchyme of the gland were dissected and divided with an ultrasonically activated scalpel and commonly used laparoscopic instruments. RESULTS: The subjects were 93 women and 7 men with ages ranging from 7 to 63 years (mean 38.9 yerars). The operation time 136+/-9.85 minutes before year 2000 and 66.8+/-8.26 at year 2000. There were 6 cases of conversion to conventional thyroidectomy, 1 case of uncontrolled intraoperative bleeding, 1 case of invasive follicular carcinoma and 4 papillary carcinoma. Postoperative complications occurred in 5 cases; 1 case of permanent recurrent laryngeal nerve palsy, 3 cases of transient voice change and 1 case of severe chest discomfort for 3 months. There was no occurrence of subcutaneous emphysema. The average of postoperative hospitalization time was 4.5+/-0.35 days. Operative scars were completley concealed by clothes and the patients were satisfied with the cosmetic result. CONCLUSION: This approach completely avoided operative scars in the neck and resulted in satisfactory cosmetic result with minimal scars in the breast. We believe that endoscopic thyroidectomy using breast approach is feasible and safe for resection of thyroid tumors.

Objective To explore the feasibility and safety of endoscopic thyroidectomy via axillo-breast approach and the cervical strap muscles. Methods From January to June 2007, endoscopic thyroidectomy was performed on 21 cases in our department via axillo-breast approach and the cervical strap muscles. The operation was carried out under general anesthesia, the anterior cervical muscles was preserved and dragged ahead if necessary. The pressure of CO2 at surgical space was set at 6-8 mm Hg.Results Endoscopic unilateral partial or subtotal thyroidectomy was completed in all the patients without converting to open surgery. No complication occurred in this series. The mean operation time was 70-120 min [mean,(88.3?19.5) min], and the mean blood loss was 2-100 ml [mean, (11.5?21.8) ml]. The drainage tube was removed at 36-48 hours after the operation. And the mean postoperative hospital stay was 2 days. A 3-month follow-up showed good outcomes in terms of sensation at the surgical region and cosmetic effect. Conclusion Endoscopic thyroidectomy via axillo-breast approach and the cervical strap muscles is feasible and safe for unilateral benign thyroid lesions.
RESUMO
Objective To compare the clinical efficacy between endoscopic thyroidectomy via breast approach and conventional open thyroidectomy in patients with nodular goiter.Methods A series of 75 patients with unilateral nodular goiter was divided into two groups,either receiving endoscopic thyroidectomy through breast approach(Endoscopic Group,24 cases)or conventional open thyroidectomy(Open Group,51 cases).The therapeutic efficacy was compared between the two groups.Results In the Endoscopic Group,the endoscopic operation was successfully performed in 23 cases,whereas a conversion to open surgery was needed in 1 case because of large nodule(6 cm in diameter)and extensive adhesion of infrahyoid muscles(resulted from a previous injection therapy).The operating time was significantly longer in the Endoscopic Group(100.4?26.6 min)than in the Open Group(73.5?14.5 min)(t=5.627;P=0.000).The postoperative drainage volume in the Endoscopic Group(66.7?24.9 ml)was significantly more than that in the Open Group(13.3?6.4 ml)(t=14.403,P=0.000).The postoperative hospital stay was significantly longer in the Endoscopic Group(4.3?1.1 d)than in the Open Group(3.6?0.9 d)(t=2.886;P=0.005).The Endoscopic Group had significant higher hospital costs(11 572?1675.1 yuan)than the Open Group(5015.9?1211.0 yuan)(t=19.058;P=0.000).And a satisfactory cosmetic result was achieved in significantly more patients in the Endoscopic Group(22/24 cases)than in the Open Group(34/51 cases)(?2=7.235;P=0.007).There was no significant difference in intraoperative blood loss between the Endoscopic Group(22.5?15.3 ml)and the Open Group(18.3?7.5 ml)(t=1.273;P=0.207),and in consumption of analgesics between the Endoscopic Group(9/24 cases)and the Open Group(21/51 cases)(?2=0.028;P=0.867),respectively.No severe complications were encountered,such as massive hemorrhage,injuries of the recurrent or superior laryngeal nerve,or parathyroid gland injury.During a follow-up for 6 months,none of the patients was found recurrence after surgery.Conclusions Both breast approach endoscopic thyroidectomy and conventional open thyroidectomy are safe and effective.The former gives better cosmetic outcomes but slower recovery and high hospital costs compared to the latter.
