“…Moreover, in the study by Wang H et al, one patient was referred to the sternal approach due to bleeding [ 20 ]. No postoperative complications occurred in the MSVATS group, while the IVATS group had an 8% (6/75) postoperative complication rate, which included pneumonia, delayed wound healing, and cardiac arrhythmias, as described in the study by Bin Li and colleagues [ 16 ]. Postoperative myasthenia crisis after thymectomy has been reported to occur at rates ranging from 6–34% [ 33 ].…”

Objective The efficacy and safety of subxiphoid thoracoscopic thymectomy (SVATS) for early thymoma are unknown. The purposes of this meta-analysis were to evaluate the effectiveness and safety of SVATS for early thymoma, to compare it with unilateral intercostal approach video thoracoscopic surgery (IVATS) thymectomy, and to investigate the clinical efficacy of modified subxiphoid thoracoscopic thymectomy (MSVATS) for early anterior mediastinal thymoma. Methods Original articles describing subxiphoid and unilateral intercostal approaches for thoracoscopic thymectomy to treat early thymoma published up to March 2023 were searched from PubMed, Embase, and the Cochrane Library. Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were calculated and analyzed for heterogeneity. Clinical data were retrospectively collected from all Masaoka stage I and II thymoma patients who underwent modified subxiphoid and unilateral intercostal approach thoracoscopic thymectomies between September 2020 and March 2023. The operative time, intraoperative bleeding, postoperative drainage, extubation time, postoperative hospital stay, postoperative visual analog pain score (VAS), and postoperative complications were compared, and the clinical advantages of the modified subxiphoid approach for early-stage anterior mediastinal thymoma were analyzed. Results A total of 1607 cases were included in the seven studies in this paper. Of these, 591 cases underwent SVATS thymectomies, and 1016 cases underwent IVATS thymectomies. SVATS thymectomy was compared with IVATS thymectomy in terms of age (SMD = − 0.09, 95% CI: −0.20 to − 0.03, I2 = 20%, p = 0.13), body mass index (BMI; SMD = − 0.10, 95% CI: −0.21 to − 0.01, I2 = 0%, p = 0.08), thymoma size (SMD = − 0.01, 95% CI: −0.01, I2 = 0%, p = 0.08), operative time (SMD = − 0.70, 95% CI: −1.43–0.03, I2 = 97%, p = 0.06), intraoperative bleeding (SMD = − 0.30. 95% CI: −0.66–0.06, I2 = 89%, p = 0.10), time to extubation (SMD = − 0.34, 95%CI: −0.73–0.05, I2 = 91%, p = 0.09), postoperative hospital stay (SMD = − 0.40, 95% CI: −0.93–0.12, I2 = 93%, p = 0.13), and postoperative complications (odds ratio [OR] = 0.94, 95% CI: 0.42–2.12, I2 = 57%, p = 0.88), which were not statistically significantly different between the SVATS and IVATS groups. However, the postoperative drainage in the SVATS group was less than that in the IVATS group (SMD = − 0.43, 95%CI: −0.84 to − 0.02, I2 = 88%, p = 0.04), and the difference was statistically significant. More importantly, the postoperative VAS was lower in the SVATS group on days 1 (SMD = − 1.73, 95%CI: −2.27 to − 1.19, I2 = 93%, p < 0.00001), 3 (SMD = − 1.88, 95%CI: −2.84 to − 0.81, I2 = 97%, p = 0.0005), and 7 (SMD = − 1.18, 95%CI: −2.28 to − 0.08, I2 = 97%, p = 0.04) than in the IVATS group, and these differences were statistically significant. A total of 117 patients undergoing thoracoscopic thymectomy for early thymoma in the Department of Thoracic Surgery of the Second Hospital of Jilin University were retrospectively collected and included in the analysis, for which a modified subxiphoid approach was used in 42 cases and a unilateral intercostal approach was used in 75 cases. The differences between the two groups (MSVATS vs. IVATS) in general clinical characteristics such as age, sex, tumor diameter, Masaoka stage, Word Health Organization (WHO) stage, and intraoperative and postoperative conditions, including operative time, postoperative drainage, extubation time, postoperative hospital stay, and postoperative complication rates, were not statistically significant (p > 0.05), while BMI, intraoperative bleeding, and VAS on postoperative days 1, 3, and 7 were all statistically significant (p < 0.05) in the MSVATS group compared with the IVATS group. Conclusion The meta-analysis showed that the conventional subxiphoid approach was superior in terms of postoperative drainage and postoperative VAS pain scores compared with the unilateral intercostal approach. Moreover, the modified subxiphoid approach had significant advantages in intraoperative bleeding and postoperative VAS pain scores compared with the unilateral intercostal approach. These results indicate that MSVATS can provide more convenient operation conditions, a better pleural cavity view, and a more complete thymectomy in the treatment of early thymoma, indicating that is a safe and feasible minimally invasive surgical method.

“…However, an alternative viable surgical pathway, the subxiphoid VATS, was chosen. Studies have demonstrated that compared to the lateral intercostal thoracic approach, the subxiphoid approach offers advantages in reducing intraoperative bleeding, postoperative hospital stay, postoperative thoracic drainage, and in lowering postoperative pain scores and analgesic medication usage [ 20 ]. The subxiphoid approach provides enhanced bilateral thoracic visualization, more thorough thymectomy, reduced trauma, and superior cosmetic outcomes, proving to be a safe and feasible minimally invasive surgical technique [ 21 ].…”

This case report details a rare thymic basaloid carcinoma initially misinterpreted as a mediastinal teratoma, underscoring the diagnostic challenges posed by such tumors. A 71-year-old female presented with an asymptomatic anterior mediastinal tumor discovered incidentally during a routine health examination. Surgical intervention, followed by pathological and immunohistochemical analysis including CK-pan, p63, p40, and CD117 molecules, led to a definitive diagnosis of basaloid carcinoma of the thymus. This case highlights the critical importance of differential diagnosis in mediastinal lesions, especially those presenting with multilocular thymic cysts on chest CT. The subxiphoid video-assisted thoracoscopic surgery enabled complete tumor resection with minimal trauma and favorable postoperative outcomes. The patient opted against further radiotherapy or chemotherapy and she has survived for over eight months without recurrence. This case report contributes to the growing understanding of thymic basaloid carcinoma, a rare and potentially aggressive thymic carcinoma subtype. It emphasizes the necessity for precise surgical techniques and enhanced diagnostic acumen among cardiothoracic surgeons and oncologists.

BackgroundThymoma is a primary tumor of the thymus, commonly located in the anterior mediastinum. Most thymomas are benign or low‐grade malignant, but they can invade surrounding organs or metastasize. The primary treatment for thymoma is surgical resection. Traditional methods involve open thoracotomy, but it is traumatic, with slow recovery and many complications. In recent years, with the development of thoracoscopic techniques, thoracoscopic total thymectomy has gradually become the preferred method for small size thymomas due to its minimally invasive, safe, and effective.MethodsThis paper introduces a thoracoscopic extend thymectomy technique, the subxiphoid video–assisted thoracoscopic extend thymectomy with sternal suspension. This method involves placing hooks at the upper and lower ends of the sternum to suspend the sternum upward, increasing the thoracic cavity space and facilitating thoracoscopic operations. This research reviews the clinical data of 59 patients with early‐stage thymomas treated with this technique at our center since 2020 and analyzes the perioperative therapeutic efficacy and safety. It also compares the outcomes with those of 17 patients who underwent thoracoscopic approaches.ResultsThe results show that subxiphoid video–assisted thoracoscopic total thymectomy with sternal suspension is an innovative and effective surgical method, achieving the same tumor eradication as other thoracic surgeries. The flexible switching of observation ports provides a more comprehensive surgical field, reduces surgical trauma and complications, and improves the surgical outcomes and quality of life for patients.
