We hypothesized that operation time would be prolonged if BBs required more intraoperative repositioning during surgical manipulation. We compared the operation times of different surgical procedures performed using BBs with double-lumen tubes (DLTs) in uniportal VATS.<\/jats:p>\n <\/jats:sec>\n \n Materials and Methods:<\/jats:title>\n Patients who underwent intubated uniportal VATS were enrolled retrospectively from March to May 2019. Data on the patient, anesthetic, and surgical factors were collected. Regression analyses were performed to determine the effect of various factors on operation time.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n 317 patients who underwent uniportal VATS were included. Wedge resection constituted 70.7%, and anatomic resection constituted 29.3% of procedures. BBs were applied for left- and right-side wedge resection (85.6% and 78.7%, respectively) and left- and right-side anatomic resection (74.1% and 56.4%, respectively). The surgical factors significantly affecting operation time were operation procedures (\n P<\/jats:italic>\n < .01), number of lymph nodes sampled (\n P<\/jats:italic>\n < .001), and size of tumors (\n P<\/jats:italic>\n < .01).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n The efficacy of BBs was comparable to that of DLTs for uniportal VATS wedge resection. With significantly less preference for right-side anatomic resection, the efficacy of DLTs was comparable with that of BBs, which were applied in more than half of right-side uniportal anatomic VATS. We conclude that even in uniportal VATSs, rigid-angled BBs demonstrate comparable efficacy with feasible alternatives.<\/jats:p>\n
