Efficacy evaluation of transaxillary non-inflatable endoscopic surgery and open neck surgery in the treatment of PTC: a single center report of 342 cases / 临床耳鼻咽喉头颈外科杂志

Objective:To compare the clinical effect of transaxillary non-inflatable endoscopic surgery and traditional open thyroid surgery in the treatment of PTC. Methods:A retrospective analysis was performed on 342 patients with PTC treated in the Otorhinolaryngology Department of Qilu Hospital of Shandong University from December 2020 to December 2022. There were 73 males and 269 females, aged 16-72 years, who underwent unilateral non-inflatable transaxillary endoscopic thyroid surgery（endoscopic group） and unilateral traditional open thyroid surgery（open group）. There were 108 patients in the endoscopic group and 234 in the open group. Results:The endoscopic group was lower in age（37.1±9.4 vs 43.5±11.2） years and BMI（23.4±3.4 vs 25.7±3.8 ）kg/m² than that in the open group, and the difference was statistically significant（t was 5.53, 5.67 respectively, P<0.01）. There was no significant difference in hospitalization days between the two groups（P>0.05）. The logarithmic curve of the operation time showed a smooth downward trend, and the overall operation time of the endoscopic group was relatively consistent. There was no significant difference in intraoperative blood loss between the endoscopic group（13.3±3.2） mL and the open group（14.7±6.3） mL（P>0.05）, but the operation time（130.1±37.9） min was longer than that in the open group（57.4±13.7） min, and the difference was statistically significant（t=19.40, P<0.01）. There was no significant difference in complications such as temporary recurrent laryngeal nerve injury within 3 days after operation between the two groups（P>0.05）. The aesthetic satisfaction score of the surgical incision and the incision concealment effect score in the endoscopic group were higher than those in the open group, and the difference was statistically significant（P<0.05）. Conclusion:Compared with traditional open thyroidectomy, transaxillary non-inflatable endoscopic thyroidectomy has more advantages in the concealment and aesthetics of postoperative incision. Although the former has longer operation time and more drainage, it is still a safe and feasible surgical method with good postoperative clinical effect.

Treatment of scapular glenoid fracture through axillary approach / 中华创伤骨科杂志

Objective:To evaluate the clinical efficacy of the axillary approach in the treatment of scapular glenoid fracture.Methods:A retrospective analysis was performed of the 12 patients who had been treated for scapular glenoid fracture from November 2019 to April 2021 at Department of Upper Limb Orthopaedics, Zhengzhou Orthopaedic Hospital. They were 4 males and 8 females, aged from 30 to 75 years (mean, 53.5 years). According to the Ideberg classification, there were 2 cases of type Ⅰa, 9 cases of type Ⅱ and one case of type Ⅴa. All cases were treated through the axillary approach. Two patients complicated with anterior shoulder dislocation were treated with manual reduction under anesthesia before operation and the other 10 cases with special plate fixation through the axillary approach. The 3 patients complicated with fracture of greater tuberosity were fixated with a special plate through the lateral shoulder split deltoid approach. Constant-Murley score, visual analogue scale (VAS) and Hawkins grading were used at the last follow-up to evaluate shoulder function, pain and stability after operation.Results:All patients were followed up for 9 to 20 months (mean, 14.4 months). The operation time ranged from 55 to 110 min (mean, 76.3 min), intraoperative bleeding from 60 to 160 mL (mean, 103.8 mL), and hospital stay from 8 to 14 d (mean, 11.1 d). All incisions healed primarily and all scapular glenoid fractures got united 6 months after operation. The last follow-up showed no shoulder instability, neurovascular injury or internal fixation failure. At the last follow-up, the range of motion of the shoulder was 159.2°±26.1° in forward bending, 156.7°±29.6° in abduction, 48.3°± 15.3° in external rotation (neutral position), and 73.3°±12.3° in internal rotation (neutral position), and the Constant-Murley score was (94.0±5.3) points. The range of motion of the shoulder and Constant-Murley score were significantly improved compared with those before operation (10.8°±11.6°, 7.5°±11.4°, 5.8°±10.0°, 42.5°±16.0° and 4.9±4.0, respectively) (all P<0.05). The VAS score was 0 in 11 patients and 2 in one patient at the last follow-up. Conclusion:The axillary approach is feasible for the treatment of scapular glenoid fracture, because it is hidden and less invasive, leading to good clinical outcomes.

The rate of central compartment neck dissection was not different between the groups[(2.4±1.7)vs.(2.8±1.6),P>0.05].The operative time was longer and the amount of drainage was higher in the endoscopic than in the open group[(123.9±28.1)min vs.(48.6±9.8)min,P<0.01;(145.9±81.8)mL vs.(87.7±18.9)mL,P<0.01].Everage length of hospi-talizntion was 1 day longer in the endoscopic group. The complication rate was not statistically significantly different between the groups.The postoperative pain score of the neck and anterior chest was not different between the groups except the anterior chest pain score at day 3 after operation.The cosmetic satisfaction was greater in the endoscopic group(P<0.01).Conclusions:Endoscopic thyroidectomy using a gasless unilateral axillary approach for the management of selected patients presenting with papillary thyroid carcinoma is a safe,feasible,and cosmetically superior procedure.

Endoscopic Thyroidectomy Via the Cervico-axillary Approach for Thyroid Cancer: Initial Experience in a Single Institute / 대한내분비외과학회지

PURPOSE: Endoscopic thyroidectomy using a cervico-axillary approach (CAA) provides optimal visualization with a smaller dissection plane. Despite the excellent cosmetic results and high patient satisfaction, the surgical and oncologic safety of CAA endoscopic surgery has not been fully established. The present study evaluated the feasibility, safety, and surgical outcomes of CAA endoscopic thyroidectomy. METHODS: From October 2009 to April 2012, 100 patients with papillary thyroid cancer underwent CAA endoscopic thyroidectomy. Patient demographics, pathologic features, and surgical outcomes including complications and recurrence were collected. RESULTS: CAA endoscopic thyroidectomy was successful in all patients, and none required conversion to open thyroidectomy. All patients underwent ipsilateral thyroid lobectomy with or without central compartment neck dissection. The mean tumor size was 1.0±0.6 cm (range, 0.5~1.6), and 35.0% of tumors showed extrathyroidal extension. The mean number of harvested lymph nodes was 4.1±4.4, and metastasis was found in 12.0% of patients. The mean surgical time was 175.2±50.4 min, mean intraoperative blood loss was 42.5±69.2 ml, and the mean hospital stay was 3.3±0.6 days. There were five cases of postoperative transient hypocalcemia and eight cases of vocal cord palsy. No permanent complication or postoperative bleeding was observed. Patients continued to be seen for a median period of 63.7 months, and no recurrence of thyroid cancer was seen. CONCLUSION: CAA endoscopic thyroidectomy is a feasible and safe procedure for low-risk thyroid cancer, with excellent cosmesis. It can be recommended as an alternative option for selected patients with low-risk thyroid cancer.

Clinical Analysis of Endoscopic Thyroidectomy by the Axillary Approach for Papillary Thyroid Microcarcinoma / 대한내시경복강경외과학회지

PURPOSE: The aim of this study is to evaluate the feasibility and surgical outcomes of endoscopic thyroidectomy by the axillary approach for treating papillary thyroid microcarcinoma (PTMC). METHODS: We analyzed 56 patients who underwent endoscopic thyroidectomy by the axillary approach for treating PTMC between May 2002 and October 2008 at Bucheon ST hospital. We evaluated the operation type, the tumor size, the operative time, the hospital days, the number of retrieved lymph nodes and the complications. RESULTS: All the patients except one were women. The mean age was 40.5+/-8.7 years. All the procedure was performed by one surgeon and endoscopic thyroidectomy was done by the axillary approach. There was no conversion to open surgery. The type of operation was classified according to the extent of the surgery. The mean operative time for lobectomy and isthmectomy with CLND (24 cases) and total thyroidectomy with CLND (5 cases) was 142.5+/-40 minutes and 270+/-84.3 minutes, respectively. The mean tumor size was 0.66+/-0.46 cm. The mean number of retrieved lymph nodes was 3.7+/-2.4. The mean number of hospital days was 3.7+/-1.4 days. There were no serious complications. There were no tumor recurrence and the mean follow-up was 50.7 months. All the patients were satisfied with the cosmetic results. CONCLUSION: Endoscopic thyroidectomy by the axillary approach for PTMC is feasible and safe. Although a larger series and longer follow up are necessary, endoscopic thyroidectomy can be a alternative treatment method for selected patients with PTMC.

Gasless Endoscopic Thyroidectomy using the Trans-axillary Approach: Surgical Outcomes of 634 Patients / 대한내분비외과학회지

PURPOSE: Various techniques of minimally invasive thyroid surgery have been introduced during the past decade, including the endoscopic technique. We have developed a novel method of gasless endoscopic thyroidectomy via an axillary approach. The present report describes the technique of this method and the analysis of the surgical outcomes. METHODS: Between Dec. 2001 and Feb. 2008 (the actual operation period was 55 months), 634 patients with thyroid tumors underwent gasless endoscopic thyroidectomy via an axillary approach. The clinical and pathologic characteristics of the patients, the type of operation, the operative time, the post operative hospital stay and the post operative complications were retrospectively analyzed. RESULTS: Among the 634 patients, 176 patients had benign tumor and 458 patients had malignant tumor. The type of operationwas classified according to the extent of surgery. Lymphadenectomy (CCND, SND, MRND) was respectively performed for treating the patients with malignant tumor, depending on the indications. The mean operating time and the mean length of the post-operative hospital stay were 129.4±51.3 minutes, 3.3±1.7 days for benign tumor and 135.5±47 minutes, 3.4±0.9 days for malignancy, respectively. The mean tumor size was 2.7±1.2 (0.4~6.0) cm for benign tumor and 0.78±0.5 (0.1~4.0) cm for malignancy. Central compartment lymph node metastasis was found in 117 (25.6%) patients and lateral neck lymph node metastasis was found in 14 (3.0%) patients. There was no conversion to open thyroidectomy. As for the post-operative complications, transient hypocalcemia occurred in 19 patients, transient hoarseness was noted in 13 patients and permanent vocal cord palsy occurred in 2 patients. For the TNM stage, 406 (88.6%) patients were stage I, 51 (11.2%) patients were stage III and 1 (0.2%) patient was stage IVA. CONCLUSION: According to our experience, gasless endoscopic thyroidectomy using a trans-axillary approach is a feasible and safe method. Endoscopic thyroid surgery has become a new treatment modality for selected patients with benign tumors and it can be an effective treatment for selected patients who suffer with thyroid cancer.

Gasless Endoscopic Thyroidectomy via an Axillary Approach: Short-term Outcomes and Modifications of Approach / 대한내분비외과학회지

PURPOSE: With an accumulation of surgical experience for endoscopic or video-assisted thyroidectomy and improvements in surgical techniques and endoscopic instruments, these procedures have become a valid option for patients with benign thyroid nodules. These applications are now being expanded even to selected patients with low risk thyroid carcinomas. This study was performed to suggest new modified methods of approach on the use of a gasless endoscopic thyroidectomy via an axillary approach and to evaluate the short-term outcomes. METHODS: Between May 2004 and March 2007, 66 female patients underwent a gasless endoscopic thyroidectomy via an axillary approach. Surgical outcomes were evaluated in terms of surgical time, length of hospital stay, the incidence of perioperative complications, and patient opinion at two and four months after surgery. RESULTS: No cases required conversion to open surgery. The mean surgical time was 136.5±31.8 minutes, and the mean length of hospital stay was 4.2±1.1 days. There were two transient recurrent laryngeal nerve palsies, two minor tracheal injuries without air leakage, and two postoperative hemorrhages that required a second surgery. Only one patient (1.9%) and five patients (9.4%) complained of slight hypesthesia or paresthesia in the neck and anterior chest wall, respectively, and only three patients (5.7%) complained of discomfort while swallowing 4 months after surgery. CONCLUSION: Gasless endoscopic thyroidectomy via an axillary approach is a feasible and safe procedure and providesa minimal degree of postoperative complaints. This procedure is now a valid option for the surgical treatment of benign thyroid disease and its applications will broaden in the near future.

Gasless Endoscopic Thyroidectomy Via an Axillary Approach

PURPOSE: Surgery for thyroid disease requires skin incisions that can result in postsurgical problems, such as prominent scars, adhesions and hypesthesia, as well as paresthesia of the neck. To overcome these problems we performed a gasless endoscopic thyroidectomy via an axillary approach. METHODS: Between November 2001 and April 2005, 141 patients underwent a gasless endoscopic thyroidectomy via an axillary approach. The surgical outcomes were evaluated in terms of the operating time, length of hospital stay and the incidence of perioperative complications. Patient opinions were assessed using a verbal response scale at two and four months after surgery. RESULTS: The mean operating time and length of hospital stay were 122.7+/-32.8 minutes and 3.4+/-0.9 days, respectively. No cases required either conversion to open surgery or involved significant intraoperative complications. Two months after surgery, 75 patients (53.2%) complained of hypesthesia or paresthesia in the anterior chest wall. The number of patients with such complaints (9.9%) had decreased 4 months after surgery (P<0.001). Four months after surgery, only 4 patients (2.8%) complained of hypesthesia or paresthesia in the neck, and 10 (7.1%) complained of discomfort while swallowing. All patients were satisfied with the cosmetic results. CONCLUSION: A gasless endoscopic thyroidectomy via an axillary approach is feasible and safe, and provides excellent cosmetic results, with a minimal degree of postoperative complaints. This procedure provides another surgical option for the treatment of benign thyroid disease in selected patients.
