Background: We aim to evaluate the transition process from open to video-assisted thoracoscopic surgery (VATS) anatomical segmentectomies in a regional thoracic surgical unit.
Methods: In a retrospective study from January 2013 to December 2015, we identified all anatomical segmentectomies performed in our unit. Pre, peri and postoperative data were compared between the three years (2013, 2014 and 2015) and according to operative approach. Thoracotomy after VATS intraoperative biopsy was considered a conversion for the purposes of the study.
Results: A total of 86 consecutive cases [56 females and 30 males, median age 70 years (range, 43 to 83 years); median FEV1 of 78% predicted (range, 41% to 126%)] were included. There was a signi cant change in the surgical approach with time. Fifty-two cases underwent VATS (73% via single-port) and 34 open surgeries, including nine conversions. There were no postoperative deaths in the VATS group and one in the open group. Operative outcomes were similar over time with no haemorrhagic events, equivalent R1 resection and nodal stations explored in all lymph node positive patients. In node negative cases however, open surgery was associated with more extensive mediastinal exploration. Patients in 2015 had a shorter hospital stay in comparison to those in previous years [median 4 days (range, 1–15 days) vs. median 6 days (range, 3–27 days), P=0.01]. There were no differences in the incidence of complications or readmissions to hospital over time.
Conclusions: The transition over a short period of time from open to single-port VATS segmentectomy has allowed us to significantly reduce postoperative hospital stay without compromising operative or postoperative outcomes.
