Clinical application of modified subxiphoid approach or thoracoscopic mediastinal teratoma resection

Objective：To explore the clinical efficacy and safety of modified subxiphoid approach for thoracoscopic mediastinal teratoma resection. Methods：A total of 17 cases of mediastinal teratoma confirmed by pathology examination and underwent thoracoscopic mediastinal teratoma resection using the modified subxiphoid approach were retrospectively analyzed, and the clinical efficacy and surgical safety of the patients were investigated. Results：All of the 17 patients underwent successful thoracoscopic surgery. Two patients underwent partial pericardial resection. In one patient, the right lung wedge resection was performed. The tumor specimens were completely resected, and the mean diameter of the resected tumor specimens was (8.4±1.7) cm, the mean operation time was (67.8±17.3) minutes, the mean intraoperative blood loss was (48.8±31.6) mL, the mean postoperative drainage was (73.5±11.1) mL, and the mean postoperative hospital stay was (3.8±1.0) days. All patients were discharged without significant postoperative complications. Conclusions：The modified subxiphoid approach for thoracoscopic mediastinal teratoma resection is safe, reliable, and satisfactory. It is worthy of clinical promotion.
