OBJECTIVESTo evaluate the feasibility and safety of video-assisted thoracoscopic surgery (VATS), and to compare surgical results of VATS with standard median sternotomy (MS) and other minimal invasive approaches through various small incisions (SI).

METHODSTotally 111 patients underwent surgery for thymic disorders (maximun diameter ≤ 5 cm, clinical stage I-II for thymic tumors) during March 2010 to June 2012 was retrospectively reviewed. There were 46 male and 65 female patients with a mean age of (51 ± 15) years.Resection via VATS was carried out in 47 patients, via SI in 26 patients, and via MS in 38 patients. Demographic characteristics, operation time, number and cause of conversion, blood loss during operation, duration and amount of chest tube drainage, transfusion, morbidity, and length of hospital stay (LHS) were compared between the three groups.

RESULTSOf the 111 patients, 79 patients had thymic epithelia tumors (stage I 32 patients, stage II 39 patients, stage III 8 patients), 31 patients had benign cysts and 1 patient had tuberculosis.In the VATS group, there were 3 conversions among 38 patients through right-side approach, and 4 conversions among 9 patients through left-side approach. The causes for conversion included dense pleura adhesion, invasion of tumor into adjacent structures (pericardium, lung, or great vessels), and injury of the left inominate vein. There was no significant difference in operative time, blood loss or transfusion during operation, duration or amount of postoperative chest tube drainage among the 3 groups (P > 0.05). Average LHS was significantly shorter in the VATS group (5.7 ± 1.7) days than in the SI group (7.5 ± 2.2) days and the MS group (8.2 ± 1.9) days (F = 3.759, P = 0.002). Total thymectomy was performed in 74 patients, 25 patients (53.2%, 25/47) in VATS group, 11 patients (42.3%, 11/26) in SI group, and 38 patients (100%, 38/38) in MS group. The reset of the patients received tumor resection and partial thymectomy. Among all the subgroups, LHS was the shortest in VATS total thymectomy patients (5.0 ± 1.4) days (F = 5.844, P = 0.001). There was no perioperative mortality. The only major morbidity was a postoperative bleeding necessitating reintervention in SI group.

CONCLUSIONSVATS for benign thymic lesions and early-stage thymic tumors is safe and feasible.It is associated with shorter hospital stay compared with other minimal invasive approaches or standard sternotomy.

Surgery is the most important therapy for thymic malignances. The last decade has seen increasing adoption of minimally invasive surgery (MIS) for thymectomy. MIS for early stage thymoma patients has been shown to yield similar oncological results while being helpful in minimize surgical trauma, improving postoperative recovery, and reduce incisional pain. Meanwhile, With the advance in surgical techniques, the patients with locally advanced thymic tumors, preoperative induction therapies or recurrent diseases, may also benefit from MIS in selected cases.

The actual incidence of multiple thymoma is unknown and rarely reported because it remains controversial whether the cases represent a disease of multicentric origin or a disease resulting from intrathymic metastasis. In this case, a patient underwent total thymectomy for multiple thymoma with myasthenia gravis via bilateral video-assisted thoracic surgery. A well-encapsulated multinodular cystic mass, measuring 57 mm×50 mm×22 mm in the right lobe of the thymus, and a well-encapsulated mass, measuring 32 mm×15 mm×14 mm in the left lobe, were found. Both tumors were type B2 thymoma. Few cases of multiple thymoma with myasthenia gravis have ever been reported in the literature. We report a case of synchronous multiple thymoma associated with myasthenia gravis.

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.

Microcystic adnexal carcinoma (MAC) is an uncommon skin appendage neoplasm with both follicular and sweat duct differentiation. It usually extends microscopically far beyond assessed clinical margins and spreads locally in the dermal, subcutaneous fat, muscle, and perineural tissue planes. Although its metastasis is very rare, local recurrence rate after standard excision is 40~59%. Recently, Mohs micrographic surgery (MMS) was introduced for the treatment of MAC and a more favorable cure rate has been reported. We report a case of MAC, which was treated by MMS, which concurred with thymoma and thyroid papillary carcinoma in a 50-year-old woman.

Breast metastasis from nonmammary malignant neoplasms is uncommon, and it accounts for approximately 2% of all breast tumors. Distant metastasis of thymoma is very rare, and especially to extrathorcic areas. We report a female who had a metastatic thymoma in her breast 20 years after undergoing resection for a non-invasive thymoma. She presented with a palpable mass in her left breast. Mammography and ultrasonogram showed a lobular mass at the anterior glandular portion. Histological examination after surgical excision revealed a metastatic thymoma.
