Ultrafine pigtail chest tubes may reduce tissue injury and improve wound healing compared with traditional drainage methods, yet evidence supporting their safety and feasibility in U-VATS patients is insufficient.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      This retrospective multicenter cohort study enrolled 1,076 lung tumor patients who underwent U-VATS across three Chinese hospitals.

After PSM (93 cases\/group), the double 8F group had significantly lower NRS pain scores [postoperative days (POD) 1\u20133], reduced early drainage volume (POD1 and POD3), and lower incidences of atelectasis and intrathoracic hemorrhage (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05) compared with the 22F\u202f+\u202f8F group. It showed comparable hospital stay and total drainage volume to the other two groups.
