BackgroundAs a new surgical procedure for non-small cell lung cancer, single-port video-assisted thoracoscopic surgery (VATS) has lately gained popularity; nevertheless, it is unknown if single-port VATS offers any advantages over multi-portal. The study aims to assess the different impacts of using single-port VATS versus 2-port or multi-port VATS such as operation and drainage time, blood loss volume, number of resected lymph nodes, and hospital stay in lung cancer patients.MethodsInclusion criteria included studies from different languages that compare single-port against 2 or multi-port VATS. The outcomes of these studies were analyzed using a random-effect model and it was used to calculate the mean difference with 95 percent confidence intervals to quantify the impact of different surgical techniques on clinical parameters.ResultsSingle or Uni-portal video-assisted thoracoscopic surgery results in significantly lower drainage time after surgery compared with 2-port (P = .03) and multi-port (P < .001) VATS. In contrast to the resection of lymph nodes, there was no significant difference between uni-port and 2-port (P = .49) or multiport (P = .29) VATS. While operation time, blood loss, complications, and hospital stay were significantly lower in uni-port compared with multi-port VATS (P = .04, P = .002, P < .001, respectively), but not with 2-port VATS (P = .44, 0.06, P = .13). There were no significant differences between uni-port and multi-port VATS regarding conversion rate, mortality, and staging.ConclusionSingle or Uni-portal video-assisted thoracoscopic surgery has high efficacy and lower side effects compared with multi-port regarding the perioperative outcomes. Two-port VATS has similar results with uni-port in several parameters.Copyright © 2023 the Author(s). Published by Wolters Kluwer Health, Inc.
