磁锚定技术辅助胸腔镜肺切除术的临床应用效果

Objective: To investigate the clinical application of self-developed magnetic anchoring device for assisting thoracoscopic pulmonary resection. Methods: Eleven patients underwent thoracoscopic pulmonary assisted with resection magnetic anchoring technique at the Department of Thoracic Surgery, The First Affiliated Hospital of Xi'an Jiaotong University, from March to May 2019. Their clinical data were retrospectively analyzed. The operation time, blood loss, blood transfusion volume, postoperative hospital stay, and postoperative complications were recorded. Results: There were seven male and four female patients, with the average age of (51.6±13.9) years (range from 22 to 69 years). Three single-port and eight single-utility-port thoracoscopic surgeries were performed. Magnetic instruments provided good surgical field exposure in all operations. Among 11 surgeries, one was converted to thoracotomy and one to three-hole surgery due to enlargement and adhesion of hilar lymph nodes. The operation time was (107.8±63.1) minutes (range of 27-182 minutes). The blood loss was 50 (10-50)mL (range of 5-1 000 mL). No blood transfusion was needed during the operation. The postoperative hospital stay was (5.0±1.8) days (range of 3-9 days). No postoperative complications occurred in all the patients. Conclusion: Magnetic anchor technique can effectively alleviate the "chopstick effect" in thoracoscopic surgery. Magnetic anchor technique is safe and feasible in assisting thoracoscopic pulmonary resection.
