〔Abstract〕 Objective To explore the feasibility of single utility port thoracoscopic surgery for benign tumor on apical chest.Methods From January 2017 to March 2021, 7 cases with benign tumor on apical chest underwent single utility port thoracoscopic surgery in our hospital were collected, and their clinical effects and complications were analyzed. Results Tumors were successfully and completely resected in all patients, including 4 schwannomas, 2 ganglioneuromas and 1 vascular tumor. Operation time ranged from 85 to 145 minutes, with an average of (111.3 ± 21.0) minutes; intraoperative blood loss was (20 ~ 50) mL, with an average of (37.1 ± 12.5) mL; postoperative drainage volume was (80~ 240) mL, with an average of (161.4 ± 54.3) mL. In 2 cases with Horner’s syndrome, one case gradually relieved at one month after operation, and some functions recovered after one-year followup; the other one had Horner’s syndrome before operation, but the postoperative condition was aggravated, and showed no remission after one-year follow-up; 2 cases with upper limb pain, numbness and activity limitation on the surgical side were gradually relieved after exercise and physical therapy. No other complications occurred. Conclusion Single utility port thoracoscopic surgery is safe, effective and less invasive for selected cases with benign tumor on apical chest.
