Objective To investigate the method and effectiveness of wide local excision combined with Mohs micrographic surgery for dermatofibrosarcoma protuberans (DFSP). Methods Between January 2007 and January 2010, 17 patients with DFSP were treated. There were 9 males and 8 females with an average age of 33.2 years (range, 16-55 years). Thelesions were located at head and neck (2 cases), trunk (12 cases), extremity (2 cases), and perineal region (1 case). There were 6 cases of primary DFSP and 11 cases of relapsed DFSP. The lesions presented as single or multitude nodules or fusion nodules with skin withering, scar, en plaque in the center and with ill-defined margins. The diameter of lesions ranged from 0.8 to 9.7 cm (mean, 4.3 cm). No distant metastasis or lymphatic metastasis occurred in all cases. After tumors resection by wide local excision combined with Mohs micrographic surgery, the wounds were repaired by direct suture in 3 patients, skin grafting in 9 patients, and local skin flap in 5 patients. Results Wide local excision and Mohs micrographic surgery were carried out once in 13 patients, twice in 3 patients, and three times in 1 patient with an average operation time of 98.6 minutes (range, 56-219 minutes). Primary heal ing of wound and donor site were achieved with no necrosis of skin grafting and skin flap. All patients were followed up 8-34 months (mean, 21.7 months) with no recurrence. Conclusion Wide local excision combined with Mohs micrographic surgery could treat DFSP, which has the advantages of shorter operation time, radical resection, and less injury.

ObjectiveTo investigate the long-term efficacy and the influencing factors of thymectomy for thymoma patients associated with myasthenia gravis. MethodsWe retrospectively analyzed the clinical and follow-up data of 126 thymoma patients associated with myasthenia gravis underwent extended thymectomy from June 2002 to December 2015 in our hospital. There were 26 males and 37 females at the mean age of 54.51±12.62 years. We built up survival analysis model to analyze the effect of those following factors on postoperative result:sex, the age when operated, the preoperative course of disease, the condition of associating with other diseases, history of critical illness, steroid administration time before operation, Osserman classification, Masaoka staging, WHO pathological type, surgical approach, tumor size and so on. Result The average follow-up time was 35(5-96) months. During follow-up period, 12 patients (19%) achieved complete remission, 39 patients (62%) achieved partial remission, 7 patients (11%) kept stable, 5 patients (8%) deteriorated and the total effective rate was 81%. The result of log-rank analysis showed that the preoperative course of disease (P=0.027), history of critical illness on myasthenia gravis (P=0.035) and Osserman classification (P=0.018) were related to incomplete remission, whlie the result of Cox regression analysis showed that the preoperative course of disease (P=0.001) and Osserman classification (P=0.012) were the independent risk factors for incomplete remission. ConclusionExtended thymectomy is an effective treatment for thymoma patients associated with myasthenia gravis, but the symptom of those patients whose preoperative course of disease are more than 12 months or Osserman classification is at ⅡB, Ⅲ and Ⅳ type of Osserman classification have poor effect after operation.
Objective To evaluate the effectiveness and advantages of the wide local excision for Paget’s disease involing the penis and scrotum by comparing with the radical excision. Methods A retrospective analysis was made on the clinical data of 41 patients with Paget’s disease involving penis and scrotum who met the inclusion criteria between November 2010 and August 2015. Among them, 14 patients received wide local excision (group A), and 27 patients received radical excision (group B). No significant difference was found in age, course of disease, and lesion site between two groups (P>0.05). The recurrence rate, operative time, times of intraoperative frozen section pathology, hospitalization time, grade of wound healing, appearance and functions satisfaction were recorded and compared between two groups. Results The operative time and hospitalization time in group A were significantly shorter than those in group B (P<0.05); the times of intraoperative frozen section pathology in group A were significantly less than that in group B (P<0.05). All patients were followed up 13 to 67 months (mean, 35.5 months) in group A and 11 to 70 months (mean, 38.8 months) in group B. Grades A, B, and C wound healing was obtained in 11 cases, 2 cases, and 1 case of group A and in 12 cases, 7 cases, and 8 cases of group B respectively, showing significant difference between two groups (Z=–2.102, P=0.036). The 5-year recurrence rate was 28.6% (4/14) in group A and 22.2% (6/27) in group B, showing no significant difference (χ2=0.202, P=0.654). The score of satisfaction in appearance and functions in group A was significantly higher than that in group B (t=–2.810, P=0.008). Conclusion Paget’s disease involving penis and scrotum has a slow disease progression and good prognosis. Wide local excision can relieve symptoms effectively and obviously decrease perioperative risk in elderly patients, with no significant increase of the recurrence rate.
Objective To assess the long-term results and relevant influencing factors of extended thymectomy and medicine-alone treatment of non-thymomatous myasthenia gravis (MG) patients. Methods We retrospectively analyzed the clinical data of 174 patients with non-thymomatous MG diagnosed and treated in our department from December 2009 to April 2017, including 81 males and 93 females, aged 13-88 (47.1±17.8) years. According to the different treatment methods, the patients were divided into two groups: an operation group (91 patients receiving extended thymectomy) and a medicine-alone group (83 patients receiving medical therapy alone). The efficacy was evaluated according to the Myasthenia Gravis Foundation of America (MGFA). Survival curves of the patients were plotted using the Kaplan-Meier method to evaluate the remission rate and survival rate. Cox regression analysis was used to assess the influencing factors of the outcomes. Results The patients were followed up for 3 to 94 (39.1±26.9) months. As a result, 29 patients (31.9%) achieved complete remission in the surgery group and 13 patients (15.7%) were completely relieved in the medicine-alone group (P=0.014). Further analysis showed that treatment pattern (P=0.018) and MG type (P=0.021) were the main factors related to the efficacy. Conclusion For patients with non-thymomatous MG, extended thymectomy is superior to the medicine-alone in terms of complete remission rate and the postoperative immunosuppression ratio.
Objective To compare three surgical treatments for mediastinal mass with myasthenia gravis. Methods Retrospective analysis was performed on the clinical data of 53 patients who underwent extended thymectomy between January 2010 and December 2017 in our hospital. There were 29 males and 24 females, aged 17-73 years. Patients were divided into three groups according to the surgical methods: a group A (video-assisted thoracoscopic surgery with the da Vinci robotic system, n=22), a group B (video-assisted thoracoscopic surgery, n=12) and a group C (median sternotomy, n=19). The gender distribution, age, intraoperative blood loss, operation time, postoperative extubation time, postoperative hospital stay, Osserman classification of myasthenia gravis, postoperative myasthenic remission rate, etc were compared in three groups. Results No perioperative death was observed in 53 patients. One patient in the group C suffered from postoperative myasthenic crisis and improved after active treatment. One patient with video-assisted thoracoscopic surgery was converted to median sternotomy due to the intraoperative injury of the left brachiocephalic vein. Compared with the group B and group C, the group A had shorter operation time, less intraoperative blood loss and drainage on the first postoperative day and fewer days of extubation. Postoperative hospital stay was less in the group A than that in the group C (P<0.05). The postoperative myasthenic remission rate was higher in the group A than that in the other two groups, but there was no statistical difference. Conclusion Because of the robot’s unique minimally invasive advantage, in this study, the outcome of patients with myasthenia gravis treated with Da Vinci robots and thymectomy is better than that of the remaining two groups in terms of perioperative outcomes and myasthenic remission rate. But long-term results and a large of number matching experiments are needed to confirm. However, it is undeniable that robotic surgery must be the future of the minimally invasive surgery.
ObjectiveTo investigate the clinical characteristics of uniportal and three-port subxiphoid video-assisted thoracoscopic surgery (XVATS) extended thymectomy.MethodsThe clinical data of 60 consecutive patients of XVATS thymectomy in Xuzhou Central Hospital from January 2017 to May 2019 were retrospectively analyzed. There were 29 males and 31 females, with an average age of 53.1 (27.0-76.0) years. The patients were divided into an uniportal XVATS group (30 patients) and a three-port XVATS group (30 patients). The clinical effectiveness was compared between the two groups.ResultsThere was no significant difference in age, sex, body mass index, tumor size, intraoperative blood loss, postoperative time of thoracic tube indwelling and thoracic drainage, or postoperative hospitalization time between the two groups (P>0.05). There was no perioperative mortality, conversion to thoracotomy, thrombosis or mediastinal infection. The operation time of the uniportal XVATS group was significantly longer than that of the three-port group (87.5±19.0 min vs. 75.8±15.7 min, P=0.012). Besides, patients in the uniportal group had significantly lower pain score during 3-14 postoperative days than that of the three-port group (P=0.001).ConclusionUniportal XVATS extended thymectomy is feasible with less pain as compared with the patients using three-port XVATS, but it needs longer operation time at initial stage.
Myasthenia gravis (MG) is an autoimmune disease with indefinite pathogenesis. MG is closely related to thymic diseases, and thymectomy is an important way for MG treatment. However, there are some controversies regarding thymectomy, including indications, operation opportunities, operative procedures, surgical approaches, perioperative managements, and efficacy evaluations, etc. Therefore, based on the literature and the experience of Chinese experts, this consensus has been written after careful discussion and inquiry and 29 recommendations have been made, aiming to guide surgical treatment of MG and improve the clinical outcomes.
Objective To compare the clinical efficacy of subxiphoid video-assisted thoracoscopic surgery (XVATS) and conventional intercostal VATS (CVATS) extended thymectomy for myasthenia gravis (MG). MethodsThe clinical data of MG patients who underwent extended thymectomy in the Department of Thoracic Surgery of Xuzhou Central Hospital from October 2016 to October 2021 and finished the follow-up were retrospectively reviewed. They were divided into an XVATS group and a CVATS group according to the procedure. The perioperative variables and clinical efficacy of the two groups were compared. ResultsA total of 84 patients were collected, including 43 males and 41 females, with a mean age of 52.3 years. There were 41 patients in the XVATS group and 43 patients in the CVATS group. There was no mortality, cardiopulmonary thrombosis, prolonged air leak, or mediastinal infection. Additionally, the CVATS group recorded 5 (11.6%) patients of conversion to open thoracotomy, 1 (2.3%) patient of postoperative MG crisis, 1 (2.3%) patient of bleeding in thorax, and 1 (2.3%) patient of chylothorax. The operation time (127.4±50.4 min vs. 122.9±38.6 min), intraoperative bleeding [46.9 (25.7, 79.2) mL vs. 45.7 (21.9, 92.1) mL], incidence of complications [0 vs. 7.0% (3/43)], chest tube duration (4.3±1.9 d vs. 4.8±2.8 d), follow-up time (19.1±8.5 months vs. 22.5±13.7 months), the proportion of residual mediastinal fat tissue [12.2% (5/41) vs. 4.7% (2/43)], and total MG remission rate [29.3% (12/41) vs. 51.2% (22/43)] were not statistically different between the two groups (P>0.05). However, the two groups showed significantly different incidence of conversion to open thoracotomy [0 vs. 11.6% (5/43), P=0.024], postoperative hospital stay time (8.2±3.3 d vs. 11.4±5.8 d, P=0.003) and total drainage volume [396.7 (173.8, 542.5) mL vs. 218.8 (102.1, 430.0) mL, P=0.038]. ConclusionXVATS extended thymectomy is technically safe and feasible; however, more evidence is warranted before the recommendation of this approach for the treatment of MG.
