Triport Periareolar Thoracoscopic Surgery Versus Right Minithoracotomy For Repairing Atrial Septal Defect In Adults

OBJECTIVES: Our goal was to investigate the safety and feasibility of triport periareolar thoracoscopic surgery (TPTS) and its advantages in repairing adult atrial septal defect.METHODS: Between January 2017 and January 2020, a total of 121 consecutive adult patients underwent atrial septal defect closure in our institution. Of these, 30 patients had TPTS and 31 patients had a right minithoracotomy (RMT). Operational data and clinical outcomes were compared between the 2 groups.RESULTS: The total operation time, cardiopulmonary bypass time and aortic cross-clamp time in the TPTS group were slightly longer than those in the RMT group, but there were no differences between the 2 groups. Compared with the RMT group, the TPTS group showed a decrease in the volume of chest drainage in 24 h (98.6 +/- 191.2 vs 222.6 +/- 217.2 ml; P = 0.032) and a shorter postoperative hospital stay (6.5 +/- 1.5 vs 8.0 +/- 3.7 days; P = 0.042). The numeric rating scale on postoperative day 7 was significantly less in the TPTS group than in the RMT group (2.82 +/- 1.14 vs 3.56 +/- 1.42; P = 0.034). The patient satisfaction scale for the cosmetic results in the TPTS group was significantly higher than in the RMT group (4.68 +/- 0.55 vs 4.22 +/- 0.76; P = 0.012). No differences were found in postoperative complications. No inhospital death or major adverse events occurred in the 2 groups.CONCLUSIONS: TPTS is safe and feasible for the closure of adult atrial septal defect. Compared with RMT, it has been associated with less pain and better cosmetic outcomes.
