Objective To compare the effect of conventional drainage tube and indwelling pigtail drainage catheter after thoracoscopic wedge resection of the lower lobes. Methods A retrospective analysis was performed on patients who were diagnosed with pulmonary nodules or early malignant tumors and underwent thoracoscopic minimally invasive wedge resection of the lung in our hospital from January 2018 to December 2023. A total of 68 patients who met the inclusion criteria were included, and the patients were divided into 38 patients in the conventional drainage tube group and 30 patients in the indwelling pigtail drainage catheter group. The effect of conventional drainage tube and indwelling pigtail drainage catheter on the clinically relevant outcomes after surgery was compared. Results Compared with the group with pigtail drainage catheter, the group with common drainage tube had less bleeding due to catheterization (P<0.05); the postoperative chest drainage volume was less (P<0.05); the pain score was lower when the numerical rating scale (NRS) was used to evaluate the pain after surgery (P<0.05). There was no significant difference in the incidence of residual pleural effusion or fluid before extubation between the two groups. There was no significant difference in the incidence of other postoperative complications between the two groups. Conclusion Compared with common chest drainage tube, common drainage tube and pigtail drainage catheter after thoracoscopic wedge resection of the lower lobe are a popularizable method to accelerate recovery and reduce postoperative pain.
