Safety of one 8.5-Fr pigtail catheter for postoperative continuous open gravity drainage after uniportal video-assisted thoracoscopic surgery pneumonectomy

Abstract

Abstract Objectives Uniportal video-assisted thoracoscopic surgery pneumonectomy (U-VATS-P) is feasible and safe from a perioperative standpoint. How to choose the proper chest tube and drainage method is important in enhanced recovery after surgery (ERAS) protocols. In this study, we aimed to assess the safety of one 8.5-Fr (1Fr = 0.333 mm) pigtail catheter for postoperative continuous open gravity drainage after U-VATS-P. Methods We retrospectively reviewed a single surgeon’s experience with U-VATS-P for lung cancer from May 2016 to September 2022. Patients were managed with one 8.5-Fr pigtail catheter for postoperative continuous open gravity drainage after U-VATS-P. The clinical characteristics and perioperative outcomes of the patients were retrospectively analyzed. Results In total, 77 patients had one 8.5-Fr pigtail catheter placed for postoperative continuous open gravity drainage after U-VATS-P for lung cancer. The mean age was 60.9 $$\pm$$ 7.39 (40–76) years; The mean FEV1 was 2.1 $$\pm$$ 0.6 (l/s), and the mean FEV1% was 71.2 $$\pm$$ 22.7. The median operative time was 191.38 $$\pm$$ 59.32 min; the mean operative hemorrhage was 109.46 $$\pm$$ 96.56 ml; the mean duration of postoperative chest tube drainage was 6.80 $$\pm$$ 2.33 days; the mean drainage volumes in the first three days after operation were 186.31 $$\pm$$ 50.97, 321.97 $$\pm$$ 52.03, and 216.44 $$\pm$$ 35.67 ml, respectively; and the mean postoperative hospital stay was 7.90 $$\pm$$ 2.58 days. No patient experienced complications resulting from chest tube malfunction. Ten patients experienced minor complications. One patient with nonlife-threatening empyema and bronchopleural fistula required short rehospitalization for anti-inflammatory therapy and reintubation. Three patients with chylothorax were treated with intravenous nutrition. Four patients had atrial fibrillation that was controlled by antiarrhythmic therapy. Two patients had more thoracic hemorrhagic exudation after the operation, which was found in time and was cured effectively, so they were discharged from the hospital uneventfully after early hemostatic therapy and nutritional support. Conclusions All patients in this study received early postoperative rehabilitation, and the rate of relevant complications was low. We therefore recommend a single 8.5-Fr pigtail catheter for postoperative continuous open gravity drainage as an effective, safe and reliable drainage method for the management of U-VATS-P.
