Pdf Summary

The study evaluated the safety, invasiveness, and curative efficacy of subxiphoid uniportal video-assisted thoracoscopic surgery (subxiphoid uniVATS) for anterior mediastinal tumors and myasthenia gravis (MG). The surgical outcomes of 60 patients who underwent median sternotomy and 28 patients who underwent subxiphoid uniVATS were compared. <br /><br />The patient characteristics were similar between the two groups, and there were no significant differences in tumor size. The subxiphoid uniVATS group had less intraoperative blood loss and shorter postoperative hospital stays compared to the median sternotomy group. Conversion to other approaches was required in six patients in the subxiphoid uniVATS group for reasons such as bleeding and technical difficulty. <br /><br />The study found that subxiphoid uniVATS may be a safe and less invasive procedure for anterior mediastinal tumors and MG. It was associated with less intraoperative bleeding, fewer oral analgesics, and shorter hospital stays. Dual-port thymectomy and non-intubated anesthesia without muscle relaxants were also mentioned as alternative surgical techniques for MG patients. <br /><br />Postoperative complications occurred in both groups, including myasthenic crises, atrial fibrillation, and nerve paralysis. The authors emphasized the need for attention during surgery to prevent these complications. <br /><br />All patients in the subxiphoid uniVATS group were alive, and no recurrence was observed in patients with thymomas during the observation period. <br /><br />In conclusion, subxiphoid uniVATS appears to be a safe and effective procedure for anterior mediastinal tumors and MG. However, further improvement in surgical techniques and anticipation of intraoperative problems are important. The study contributes to the growing evidence supporting the use of minimally invasive techniques in thoracic surgery.
