Clinical analysis of subxiphoid single-port thoracoscopic surgery for simultaneous bilateral lung lesion resection

OBJECTIVE: To investigate the efficacy and safety of simultaneous subxiphoid single-port thoracoscopic resection of bilateral lung lesions. METHODS: This retrospective study analyzed the clinical data of 72 patients who underwent resection of bilateral lung lesions at the Department of Thoracic Surgery in the First Affiliated Hospital of University of Science and Technology of China between August 2020 and January 2022. Surgery-related parameters were compared between patients who underwent subxiphoid single-port thoracoscopy (subxiphoid group, 36 patients) and patients who underwent intercostal single-port thoracoscopy (intercostal group, 36 patients). RESULTS: Compared to the intercostal group, the subxiphoid group exhibited significantly better postoperative catheterization time (P = 0.013), postoperative thoracic drainage, postoperative visual analog scale pain scores at 24 and 48 h, and incision pain and numbness at 1 and 3 months after surgery (all P < 0.05). There were no significant differences in operation time, intraoperative blood loss, or postoperative complications between the two groups (all P > 0.05). There were no cases of perioperative mortality, conversion to thoracotomy, or serious complications in either group. CONCLUSION: Subxiphoid single-port thoracoscopic surgery for simultaneous resection of bilateral lung lesions is safe and effective, reduces postoperative acute and chronic pain, decreases trauma, allows faster recovery, and is more consistent with the concept of minimally invasive surgery than bilateral intercostal single-port thoracoscopy. Thus, this subxiphoid single-port thoracoscopic surgery approach should be considered for clinical application.
