Tsai PC, Tseng YC, Ting YC, Huang CS, Hsu WH, Tang EK, Hsu HS. Long-term follow-up of non-myasthenic patients with early-stage thymoma who underwent extended thymectomy or limited resection. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:108349. [PMID: 38640605 DOI: 10.1016/j.ejso.2024.108349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2024] [Revised: 04/05/2024] [Accepted: 04/14/2024] [Indexed: 04/21/2024]
Abstract
BACKGROUD The standard resection for early-stage thymoma is total thymectomy and complete tumour excision with or without myasthenia gravis but the optimal surgery mode for patients with early-stage non-myasthenic thymoma is debatable. This study analysed the oncological outcomes for non-myasthenic patients with early-stage thymoma treated by thymectomy or limited resection in the long term. METHODS Patients who had resections of thymic neoplasms at Taipei Veteran General Hospital, Taiwan between December 1997 and March 2013 were recruited, exclusive of those combined clinical evidence of myasthenia gravis were reviewed. A total of 113 patients were retrospectively reviewed with pathologic early stage (Masaoka stage I and II) thymoma who underwent limited resection or extended thymectomy to compare their long-term oncologic and surgical outcomes. RESULTS The median observation time was 134.1 months [interquartile range (IQR) 90.7-176.1 months]. In our cohort, 52 patients underwent extended thymectomy and 61 patients underwent limited resection. Shorter duration of surgery (p < 0.001) and length of stay (p = 0.006) were demonstrated in limited resection group. Six patients experienced thymoma recurrence, two of which had combined myasthenia gravis development after recurrence. There was no significant difference (p = 0.851) in freedom-from-recurrence, with similar 10-year freedom-from-recurrence rates between the limited resection group (96.2 %) and the thymectomy group (93.2 %). Tumour-related survival was also not significantly different between groups (p = 0.726).result CONCLUSION: Patients with early-stage non-myasthenic thymoma who underwent limited resection without complete excision of the thymus achieved similar oncologic outcomes during the long-term follow-up and better peri-operative results compared to those who underwent thymectomy.

Perioperative outcomes and survival of modified subxiphoid video-assisted thoracoscopic surgery thymectomy for T 2-3 thymic malignancies: A retrospective comparison study. J Thorac Cardiovasc Surg 2024:S0022-5223(24)00367-2. [PMID: 38692477 DOI: 10.1016/j.jtcvs.2024.04.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 04/01/2024] [Accepted: 04/15/2024] [Indexed: 05/03/2024]
Abstract
OBJECTIVE Our previous study demonstrated that modified subxiphoid video-assisted thoracic surgery thymectomy with an auxiliary sternal retractor is feasible for locally invasive thymic malignancies. This study aimed to compare perioperative and oncological outcomes of modified subxiphoid video-assisted thoracoscopic surgery thymectomy versus median sternotomy thymectomy for locally advanced thymic malignancies. METHODS In total, 221 patients with T2-3 thymic malignancies who underwent modified subxiphoid video-assisted thoracoscopic surgery thymectomy or median sternotomy thymectomy between 2015 and 2020 were enrolled in our prospectively maintained database. A 1:1 propensity score-matching analysis was performed to balance the bias. Surgical difficulty was evaluated with a modified resection index. Perioperative and oncological results were compared between the modified subxiphoid video-assisted thoracoscopic surgery thymectomy group and the median sternotomy thymectomy group. RESULTS There were 72 patients in each group in the final analysis. Our results showed that the modified subxiphoid video-assisted thoracoscopic surgery thymectomy group had a shorter operative duration (98 vs 129 minutes, P < .001), less blood loss (40 vs 100 mL, P < .001), shorter drainage duration (3 vs 5 days, P < .001), shorter length of hospital stay (5 vs 6 days, P < .001), and fewer postoperative complications (5.6% vs 23.6%; P = .005). No significant difference was detected in complete resection (98.6% vs 98.6%, P = 1.000) between the 2 groups. Conversion occurred in 5 of 106 patients (4.7%). Survival analyses indicated similar recurrence-free survival (hazard ratio, 0.94; 95% CI, 0.40-2.20; P = .883) and overall survival (hazard ratio, 0.52; 95% CI, 0.05-5.02; P = .590) between the 2 groups. CONCLUSIONS Modified subxiphoid video-assisted thoracoscopic surgery thymectomy was safe and effective for T2-3 thymic malignancies and could be an alternative for selected patients with locally advanced thymic diseases. Further prospective studies are needed to evaluate the long-term survival of those undergoing modified subxiphoid approach thoracoscopic thymectomy.

Abstract
PURPOSE Thoracoscopic procedures such as video-assisted thoracoscopic surgery (VATS) and robot-assisted thoracoscopic surgery (RATS) have gained popularity for the treatment of thymoma. Accurate preoperative assessments of tumor invasion are crucial to identifying the appropriate surgical approach. Although imaging techniques have been used to predict invasion, a quantifiable method is still needed in clinical practice. METHODS The ubjects of this retrospective study were 226 patients with thymoma who underwent surgery at our hospital. Clinicopathological data, tumor staging, and recurrence rates were analyzed. Calcification identified through computed tomography (CT) defined the "calcified group" as having a long diameter of ≥ 5 mm. Statistical analyses were performed to assess relationships and survival outcomes. RESULTS The calcified group had higher Masaoka and World Health Organization classification than the noncalcified group, with significantly higher organ invasion rates. The calcified group also had remarkably higher recurrence rates. CONCLUSION Thymoma calcification appears to correlate with increased invasiveness and recurrence rates, suggesting its potential as a predictor of tumor stage and prognosis. Despite its retrospective nature and inherent limitations, this study highlights the potential clinical significance of calcification in the surgical planning and prognostication of patients with thymoma.

Abstract
BACKGROUND Aimed to assess clinical effect of three-port inflatable robot-assisted thoracoscopic surgery in mediastinal tumor resection by comparing results of the robot group with the video group. METHODS Retrospectively analyze 179 patients diagnosed with anterior mediastinal tumor from May 2017 to August 2021. Two groups were divided according to the surgical approach, including 92 cases in the RATS group and 87 cases in the VATS group. The results were analyzed between two groups with variables of age, sex, BMI, tumor size, and diagnosis. Perioperative clinical data was gathered to compare. RESULT There were no significant differences between the 2 groups with regards to demographic data and clinical features. There were no significant differences inoperative time and duration of chest tube via RATS vs. VATS. The intraoperative blood loss was statistically significantly different among the RATS and VATS groups (75.9 ± 39.6 vs. 97.4 ± 35.8 ml p = 0.042). The postoperative stay of patients in RATS group were significantly shorter than that in VATS group (2.3 ± 1.0 vs. 3.4 ± 1.4 day p = 0.035), CONCLUSION: Three-port inflatable robot-assisted thoracoscopic surgery for mediastinal tumor is feasible and reliable it is more advantageous, and it provides the surgeon with advice on treatment choice.

Abstract
BACKGROUND The advent of robot-assisted thoracoscopic surgery (RATS) has completely revolutionized the modality of thymectomy, which could reportedly achieve equivalent efficacy compared with a minimally invasive approach. This study was conducted to further compare the perioperative outcomes between these two modalities. METHODS A retrospective single-center study that included patients receiving either a robotic or video-assisted thoracoscopic (VAT) thymectomy between February 2021 and January 2023 was conducted. All the patients were pathologically confirmed with thymic epithelial tumors. Clinical and pathological characteristics and perioperative outcomes were collected and compared between these two cohorts. RESULTS A total of 190 patients were included in this study, with 61 (32.1%) and 129 (67.9%) receiving robotic and video-assisted thymectomy, respectively. The clinicopathological characteristics were not significantly different between these 2 groups. The size of the resected specimens in the RATS cohort was larger than the VATS cohort [median (IQR), 13.0 (8.0-16.0) vs. 9.0 (6.7-12.0) cm, p < 0.001], while the procedural duration was longer for the RATS group than its counterpart [median (IQR), 105 (85-143) vs. 85 (69-115) min, p = 0.001]. Moreover, no other significant difference was observed between these two groups. Since more than half of the robotic thymectomy was performed using a subxiphoid approach, a subgroup analysis was further conducted. Similarly, the robotic group through a subxiphoid approach harbored a longer procedural duration, and the size of the specimens obtained was larger than the VATS group [median (IQR), 14.0 (11.0-16.5) vs. 12.5 (8.5-15.0) cm, p = 0.061]. CONCLUSIONS The early clinical efficacy of robotic thymectomy was proven comparable to the established VATS approach, and such a modality might have strength when obtaining larger specimens, which could contribute to improving long-term efficacy. Despite the longer procedural duration recorded in the early stage of conducting robotic thymectomy, further accumulation would help decrease the time.

Abstract
PURPOSE Minimally invasive surgery (MIS) for thymic tumors is now accepted widely, in line with improved surgical techniques; however, we occasionally encounter complicated cases of large tumors or of total thymectomy requiring prolonged operative duration or conversion to an open procedure (OP). We reviewed patients registered in a nationwide database to identify the technical feasibility of MIS for thymic epithelial tumors. METHODS Data on patients treated surgically between 2017 and 2019 were extracted from the National Clinical Database of Japan. Clinical factors and operative outcomes were calculated by tumor diameter using trend analyses. Perioperative outcomes of MIS for non-invasive thymoma were investigated using propensity score-matched analyses. RESULTS MIS was performed in 46.2% of the patients. The operative duration and conversion rate increased with the tumor diameter (p < .001). After propensity score-matching, operative duration and postoperative hospital stay were shorter (p < .001), and the transfusion rate was lower (p = .007) in patients who underwent MIS than in those who underwent OP for thymomas ≥ 5 cm. Among patients who underwent total thymectomy, blood loss was less (p < .001) and the postoperative hospital stay was shorter (p < .001) in those who underwent MIS than in those who underwent OP. There were no significant differences in postoperative complications and mortality. CONCLUSIONS MIS is technically feasible even for large non-invasive thymomas or for total thymectomy, although the operative duration and open conversion rate increase with the tumor diameter.

Abstract
Importance Thymic carcinoma is rare, and its oncologic management is controversial due to a paucity of prospective data. For this reason, multidisciplinary consensus guidelines are crucial to guide oncologic management. Objective To develop expert multidisciplinary consensus guidelines on the management of common presentations of thymic carcinoma. Evidence Review Case variants spanning the spectrum of stage I to IV thymic carcinoma were developed by the 15-member multidisciplinary American Radium Society (ARS) Thoracic Appropriate Use Criteria (AUC) expert panel to address management controversies. A comprehensive review of the English-language medical literature from 1980 to 2021 was performed to inform consensus guidelines. Variants and procedures were evaluated by the panel using modified Delphi methodology. Agreement/consensus was defined as less than or equal to 3 rating points from median. Consensus recommendations were then approved by the ARS Executive Committee and subject to public comment per established ARS procedures. Findings The ARS Thoracic AUC panel identified 89 relevant references and obtained consensus for all procedures evaluated for thymic carcinoma. Minimally invasive thymectomy was rated as usually inappropriate (regardless of stage) due to the infiltrative nature of thymic carcinomas. There was consensus that conventionally fractionated radiation (1.8-2 Gy daily) to a dose of 45 to 60 Gy adjuvantly and 60 to 66 Gy in the definitive setting is appropriate and that elective nodal irradiation is inappropriate. For radiation technique, the panel recommended use of intensity-modulated radiation therapy or proton therapy (rather than 3-dimensional conformal radiotherapy) to reduce radiation exposure to the heart and lungs. Conclusions and Relevance The ARS Thoracic AUC panel has developed multidisciplinary consensus guidelines for various presentations of thymic carcinoma, perhaps the most well referenced on the topic.

Abstract
Objective: The aim of this study is to acquire pulmonary CT (Computed tomography) angiographic data for the purpose of creating a three-dimensional reconstruction. Additionally, we aim to analyze the features and deviations of the branches in both pulmonary lobes. This information is intended to serve as a more comprehensive and detailed reference for medical professionals when conducting preoperative evaluations and devising surgical plans. Method: Between August 2019 and December 2021, 420 patients were selected from the thoracic surgery department at the First Hospital of Jilin University, and underwent pulmonary 64 channel contrast enhanced CT examinations (Philips ICT 256). The images were acquired at a 1.5 mm slice thickness, and the DCM files that complied with DICOM (Digital Imaging and Communications in Medicine) standards were analysed for 3D (three dimensional) reconstruction using Mimics 22.0 software. The reconstructed pulmonary artery models were assessed by attending chest surgeons and radiologists with over 10 years of clinical experience. The two-dimensional image planes, as well as the coronary and sagittal planes, were utilized to evaluate the arteries. The study analyzed the characteristics and variations of the branches and courses of pulmonary arteries in each lobe of the lungs, with the exception of the subsegmental arterial system. Two chest surgeons and two radiologists with professional titles-all of whom had over a decade of clinical experience-jointly evaluated the 3D models of the pulmonary artery and similarly assessed the characteristics and variations of the branches and courses in each lobe of the lungs. Results: Significant variations were observed in the left superior pulmonary artery across the 420 subjects studied. In the left upper lobe, the blood supply of 4 arteries accounted for 50.5% (n = 212), while the blood supply of 2 arteries in the left lower lobe was the most common, accounting for 79.5% (n = 334). The greatest variation in the right pulmonary artery was observed in the branch supply of the right upper lobe mediastinal artery. In the majority of cases (77.9%), there were two arteries present, which was the most common configuration observed accounting for 64% (n = 269). In the right inferior lobe of the lung, there were typically 2-4 arteries, with 2 arteries being the most common configuration (observed in 79% of cases, n = 332). Conclusion: The three-dimensional reconstruction of pulmonary artery CT angiography enables clear observation of the branches and distribution of the pulmonary artery while also highlighting any variations. This technique holds significant clinical value for preoperative assessments regarding lesions and blood vessels.

Minimally Invasive Thymectomy Could Be Attempted for Locally Advanced Thymic Malignancies: A Real-World Study With Propensity Score-Matched Analysis. J Thorac Oncol 2023; 18:640-649. [PMID: 36642159 DOI: 10.1016/j.jtho.2022.12.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 12/07/2022] [Accepted: 12/19/2022] [Indexed: 01/15/2023]
Abstract
INTRODUCTION Increasing evidence supports minimally invasive thymectomy (MIT) for early stage thymic malignancies than open median sternotomy thymectomy (MST). Nevertheless, whether MIT could be attempted for locally advanced disease remains unclear. METHODS The clinical data of consecutive patients with stage T2-3NxM0 (eighth edition TNM staging) thymic malignancies who underwent MIT or MST were identified from a prospectively maintained database. The co-resected structures were rated with a resection index to evaluate surgical difficulty. The impact of surgical approach on treatment outcomes was investigated through propensity score-matched analysis and multivariable analysis. RESULTS From January 2008 to December 2019, a total of 128 patients were included; MIT was initially attempted in 58 (45.3%) cases, and eight (13.8%) were converted to MST during surgery. The conversion group had similar perioperative outcomes to the MST group, except for a longer operation time. After propensity score matching, the resection index scores were similar between the MIT and MST groups (3.5 versus 3.7, p = 0.773). The MIT group had considerably less blood loss (p < 0.001), fewer postoperative complications (p = 0.048), a shorter duration of chest drainage (p < 0.001), and a shorter hospitalization duration (p < 0.001) than the MST group. The 5-year freedom from recurrence rate was not different between the two groups (78.2% versus 78.5%, p = 0.942). In multivariable analysis, surgical approach was not associated with freedom from recurrence (p = 0.727). CONCLUSIONS MIT could be safely attempted in carefully selected patients with locally advanced thymic tumors. Conversion did not compromise the surgical outcomes. Patients may benefit from the less traumatic procedure and thus better recovery, with comparable long-term oncologic outcomes.

Robotic Mediastinal Tumor Resections: Position and Port Placement. J Pers Med 2022; 12:jpm12081195.

Abstract
This study aimed to determine the optimal position and port placement during robotic resection for various mediastinal tumors. For anterior mediastinal tumors, total or extended thymectomy is commonly performed in the supine position using the lateral or subxiphoid approach. Although it is unclear which approach is better during robotic thymectomy, technical advantages of subxiphoid approach are beneficial for patients with myasthenia who require extended thymectomy. Partial thymectomy is performed in the supine position using a lateral approach. Superior, middle, and posterior mediastinal tumors are resected in the decubitus position using the lateral approach, whereas dumbbell tumor resection, which requires a posterior approach, can be performed in the prone position. The position and port placement should be chosen depending on the size, location, and aggressiveness of the tumor. In this study, we describe how to choose which of these different robotic approaches can be used based on our experience and previous reports.

Abstract
BACKGROUND In recent years, with the advancement of minimally invasive techniques, thoracoscopic thymoma resection has experienced a development process from three-port video-assisted thoracic surgery (VATS) to two-port (TP) and single-port (SP) variants. However, the feasibility and safety of SP-VATS have not been generally recognized. This study intends to explore the safety and feasibility of SP-VATS in thymoma resection, in order to provide a reference for clinical surgicalselection. METHODS The clinical data of 197 patients who underwent thoracoscopic thymoma resection in Beijing Tongren Hospital from January 2018 to September 2021 were retrospectively analyzed. The patients were divided into SP-VATS group (n=42) and TP-VATS group (n=155). After matching propensity scores, there is no statistically significant difference in preoperative baseline data between SP-VATS group and TP-VATS group. Among them, there were 17 males and 25 females with an average age of 28-72 (48.00±9.43) years in the SP-VATS group, and 20 males and 22 females with an average age of 30-75 (50.38±9.83) years in TP-VATS group. The clinical effects of the two groups were compared. RESULTS The operation was successfully completed in both groups, and there was no conversion to thoracotomy or increased surgical incisions. Compared with the TP-VATS group, the chest drainage time and hospital stay in the SP-VATS group were shorter [(2.95±0.76) d vs (3.33±0.85) d; (4.57±0.83) d vs (5.07±1.13) d], and the visual pain score at 24 h and 72 h after surgery were lower [(3.64±0.85) points vs (4.05±0.66) points; (2.33±0.75) points vs (3.07±0.68) points] (P<0.05). There was no statistically significant difference between the two groups in operation time [(130.00±26.23) min vs (135.24±27.03) min], intraoperative blood loss [(69.52±22.73) mL vs (82.38±49.23) mL] (P>0.05). CONCLUSIONS SP-VATS in thymoma is a safe, feasible, and less invasive procedure, with less postoperative pain and faster recovery than multi-port VATS.

Abstract
A minimally invasive resection of thymomas has been accepted as standard of care in the last decade for early stage thymomas. This is somewhat controversial in terms of higher-staged thymomas and myasthenia gravis patients due to the prognostic importance of complete resections and the indolent characteristics of the disease process. Despite concerted efforts to standardize minimally invasive approaches, there is still controversy as to the extent of excision, approach of surgery, and the platform utilized. In this article, we aim to provide our surgical perspective of thymic resection and a review of the existing literature.

Abstract
BACKGROUND Thymic tumors usually present with adjacent organ invasion or pleural dissemination, but very few studies have reported on occult pleural dissemination detected intraoperatively. This study aimed to investigate the risk factors that can predict pleural dissemination preoperatively. METHODS Consecutive patients with thymic tumors who underwent surgery from January 2010 to January 2017 were reviewed. Only patients without pleural dissemination detected preoperatively were included in this study. Demographic, clinical, pathological, and survival data were collected for statistical analysis. Further analyses were performed to find the risk factors of occult pleural dissemination. RESULTS A total of 352 patients with thymic tumors were included in this study. Seven patients had pleural dissemination detected intraoperatively. All pleural dissemination cases were in clinical Masaoka-Koga stage III, and most underwent the video-assisted thoracoscopic surgery (VATS) approach (or VATS exploration). Univariate analysis showed that positive squamous cell carcinoma (SCC) antigen was the only predictor of pleural dissemination (p = 0.009). Tiny nodules close to the diaphragm were detected in the computed tomography scans of 1 case after reviewing the imaging data. Tumor recurrence occurred in 5 patients during follow-up. The disease-free survival rates were better in patients with a solitary nodule than those with multiple nodules (p = 0.019). No significant difference was detected in terms of disease-free survival rates between SCC antigen positive and SCC antigen negative patients. CONCLUSIONS Positive SCC antigen was the only detected risk factor for predicting pleural dissemination in thymic tumors preoperatively in this study. The VATS approach (including VATS exploration) is suggested for patients with clinical Masaoka-Koga stage III and SCC antigen positive thymic tumors, according to our experience.

Abstract
BACKGROUND Thymectomy is traditionally performed via transsternal incision, but less invasive modalities have emerged, including transcervical, thoracoscopic, and robotic approaches. Despite the advantages of video-assisted thoracoscopic surgery(VATS) over thoracotomy, most thymectomies are performed via sternotomy. This study compared the utilization and 30-day post-operative outcomes of transsternal, transcervical, and VATS thymectomy in the Veterans Health Administration. METHODS This was a retrospective review of veterans that underwent thymectomy via the Veterans Affairs Surgical Quality Improvement Program. 30-day outcomes were compared between techniques, adjusting for confounding covariates. Temporal trends were analyzed using Spearman's rank correlation coefficient, rho(ρ). RESULTS From 2008-2019, 594 thymectomies were performed: 376(63.3%) transsternal, 113(19.0%) VATS(including robotic approaches), and 105(17.7%) transcervical cases. VATS utilization increased from 0% in 2008 to 61% of case volume in 2019. Relative to transsternal technique, VATS thymectomy was associated with decreased odds of pulmonary complications (adjusted odds ratio=0.06;p=0.028) and shorter hospital stay (2.9±0.4 days shorter;p<0.001). No difference in outcomes was detected between VATS and transcervical thymectomy. Post-operative complication rate decreased from 17.7% in 2008 to 5.6% in 2019 (ρ=-0.101;p=0.014). Length of stay decreased from median 4 days in 2008 to 3 days in 2019 (ρ=-0.093;p=0.026). In thymic cancer, VATS 5-year overall survival was non-inferior to transsternal approach(71.3% vs. 74.6%; p=0.54). CONCLUSIONS Transsternal approach comprised most thymectomy cases amongst veterans, while VATS thymectomy utilization increased over time and was associated with favorable outcomes. 30-day outcomes after thymectomy improved over time, which may reflect a trend towards wider utilization of less invasive approaches. Future studies should examine long-term outcomes.

Abstract
Background Recent years have seen a trend towards utilizing a video-assisted thoracic surgery (VATS) approach for treatment of thymoma. Although increasing in practice, intermediate- and long-term oncologic outcome data is lacking for the VATS approach. There is no oncologic data for the uniportal VATS approach. We sought to evaluate the feasibility and impact on patient survival of uniportal VATS thymectomy for early-stage thymoma. Method The clinical outcomes for 17 patients with Masaoka stage I to II thymomas treated between January of 2009 and July of 2014 at a single institution were collected retrospectively. Primary endpoint was overall survival (OS) and secondary endpoint was recurrence-free survival (RFS). Results Ten women and seven men underwent uniportal VATS thymectomy; eleven had stage I thymoma and six had stage II thymoma. There were no conversions to open surgery. Operative mortality was zero. Mean tumor size was 3.8±1.0 centimeters, with a range of 1.9 to 6.0 centimeters. All patients underwent a R0 resection. Five-year survival was 100%, and the estimated RFS was 100%. Conclusions Our findings suggest that uniportal VATS thymectomy for early-stage thymoma is feasible, and the intermediate-term oncologic outcomes are comparable to historic standards for open and multi-incision VATS thymectomy. However, additional follow-up is required to evaluate for long-term oncologic outcomes.

Abstract
When the diagnosis of myasthenia gravis (MG) has been secured, the aim of management should be prompt symptom control and the induction of remission or minimal manifestations. Symptom control, with acetylcholinesterase inhibitors such as pyridostigmine, is commonly employed. This may be sufficient in mild disease. There is no single universally accepted treatment regimen. Corticosteroids are the mainstay of immunosuppressive treatment in patients with more than mild MG to induce remission. Immunosuppressive therapies, such as azathioprine are prescribed in addition to but sometimes instead of corticosteroids when background comorbidities preclude or restrict the use of steroids. Rituximab has a role in refractory MG, while plasmapheresis and immunoglobulin therapy are commonly prescribed to treat MG crisis and in some cases of refractory MG. Data from the MGTX trial showed clear evidence that thymectomy is beneficial in patients with acetylcholine receptor (AChR) antibody positive generalized MG, up to the age of 65 years. Minimally invasive thymectomy surgery including robotic-assisted thymectomy surgery has further revolutionized thymectomy and the management of MG. Ocular MG is not life-threatening but can be significantly disabling when diplopia is persistent. There is evidence to support early treatment with corticosteroids when ocular motility is abnormal and fails to respond to symptomatic treatment. Treatment needs to be individualized in the older age-group depending on specific comorbidities. In the younger age-groups, particularly in women, consideration must be given to the potential teratogenicity of certain therapies. Novel therapies are being developed and trialed, including ones that inhibit complement-induced immunological pathways or interfere with antibody-recycling pathways. Fatigue is common in MG and should be duly identified from fatigable weakness and managed with a combination of physical therapy with or without psychological support. MG patients may also develop dysfunctional breathing and the necessary respiratory physiotherapy techniques need to be implemented to alleviate the patient's symptoms of dyspnoea. In this review, we discuss various facets of myasthenia management in adults with ocular and generalized disease, including some practical approaches and our personal opinions based on our experience.

Abstract
Video-assisted thoracoscopic thymectomy is increasingly performed for thymic disorders. However, intraoperative bleeding, especially from the innominate vein, is often inevitable, and is the major reason for conversion. Successful control under thoracoscopic thymectomy is crucial for the safety of the patient. We hereby report two cases of intraoperative bleeding and strategies for safe and effective bleeding control during the conventional three-port video-assisted thoracoscopic thymectomy. The first case was an 80-year-old male patient diagnosed with cystic thymoma, and injury to a thymic vein below the left innominate vein occurred during a right thoracoscopic thymectomy. It was well managed by endovascular clips under video-assisted thoracoscopic thymectomy. The intraoperative blood loss was 50 mL. The second case was a 73-year-old female patient diagnosed with thymoma. Massive bleeding from the left innominate vein occurred due to inadvertent injury during a left approach thoracoscopic thymectomy. But it was successfully controlled via endoscopic stapler. Intraoperative blood loss was 300 mL and the patient did not receive any blood transfusion. Postoperative courses of both two cases were uneventful. Our experience shows that endoscopic clipping or stapling respectively can provide safe, quick, and effective control of different types of bleedings under video-assisted thoracoscopic thymectomy. This technique is helpful to ensure the safety and success of minimally invasive surgery for thymic diseases.

Abstract
Background Video-assisted thoracoscopic surgery (VATS) is now increasingly used for the treatment of early stage thymic malignancies. However, VATS has not been advocated for patients with locally advanced diseases. We reviewed our initial experience in VATS thymectomy with partial superior vena cava (SVC) resection for IASLC/ITMIG stage III thymic tumors. Methods From August 2017 to October 2018, patients who underwent VATS thymectomy with partial SVC resection were retrospectively reviewed, and peri-operative outcomes and short-term follow-up results were analyzing. Results Four patients with partial SVC resection via VATS were identified. All of them had pathologically confirmed IASLC/ITMIG stage III thymic tumors invading the SVC. The average of operative time was 228 minutes and mean blood loss was 88 mL. The mean duration of chest tube drainage and post-operative hospital stay were 4.5 and 7.3 days respectively. No major complication was encountered after surgery. No mortality was observed. And no recurrence was detected with the longest follow-up time of 14 months. Conclusions With careful patient selection and plenty surgical expertise, VATS thymectomy for locally invasive thymic tumors with limited the SVC invasion is challenging yet technically feasible.
