Introduction: Early water seal following minimally invasive pulmonary lobectomy has been shown to reduce chest tube duration and postoperative length of stay (LOS). We evaluated chest tube duration and postoperative LOS following a standardized chest tube management protocol change (water seal on postoperative day 1) after video-assisted thoracic surgery (VATS) pleurodesis.
Methods: We identified adult patients undergoing VATS pleurodesis from August 2013 to December 2021. The chest tube protocol was changed in January 2017 such that patients were placed to water seal on the morning of postoperative day 1. Patients were divided into two groups, before the change (Group 1: August 2013-December 2016) and after (Group 2: January 2017-December 2021). We compared demographics, clinical characteristics, operative details, postoperative chest tube duration and output, and postoperative LOS between the groups. Descriptive statistics and log-transformed multivariable linear regression models were used to identify differences in patient outcomes that were associated with the protocol change.
Results: A total of 488 patients underwent VATS pleurodesis during the study period (Group 1: 329 patients; Group 2: 159 patients). The median age was 61 y (interquartile range [IQR] 49-68), 51% were females, 69% were White, and 29% were Black. For postoperative LOS, Group 1 had an IQR of 3-7 d, while Group 2 had an IQR of 2-6 d (P < 0.001). The multivariable log-transformed linear regression models demonstrated that the practice change was associated with reduced chest tube duration (0.77 times the chest tube duration before the change; P < 0.001) and reduced LOS (0.81 times the LOS before the change; P = 0.006). There was an associated reduction in patients needing to return to the operating room (P = 0.048) and needing postoperative extended ventilatory support (P = 0.035).
Conclusions: Development of a standardized protocol to water seal chest tubes on postoperative day 1 following VATS pleurodesis is associated with reduced chest tube duration and LOS without an increase in postoperative complication rates.
