Are the Efficacy and Safety of Chest Tubes in Uniportal Video-Assisted Thoracic Surgery Related to the Level of Intercostal Space Insertion or to the Drain Type? A Prospective Multicenter Study

Abstract

Objectives: The aim of this study is to evaluate if the efficacy and safety of chest tube placement are influenced by the level of intercostal space insertion (uniportal VATS vs. biportal VATS) or by the type of drain employed (standard vs. smart coaxial drain). Methods: Data on patients who underwent either uniportal or biportal VATS upper lobectomies with lymphadenectomy were prospectively collected in three European centers. The uniportal VATS group with a 28 Fr standard chest tube (U-VATS standard) was compared with the uniportal VATS group with a 28 Fr smart drain (U-VATS smart), and U-VATS smart was also compared with biportal VATS with a 28 Fr smart drain inserted in the VIII intercostal space (Bi-VATS smart). Results: When comparing the U-VATS standard group with the U-VATS smart, a higher fluid output was recorded in the U-VATS smart (p: 0.004) in the III post-operative day (p.o.) and overall (p: 0.027), with a lower 90-day re-admission in the U-VATS smart (p: 0.04). The Bi-VATS smart group compared to U-VATS smart showed a higher fluid output in the I p.o. (p < 0.001), with no difference in total fluid amount or hospitalization. The Bi-VATS smart recorded a lower incidence (p < 0.001) of residual pleural space or effusion (p: 0.004) at chest X-rays prior to drain removal but a higher level of pain and chronic intercostal neuralgia (p: 0.03). Conclusions: Chest tube insertion through the same incision space in uniportal VATS seems to be safe and effective. Smart drains can improve the fluid output in uniportal VATS, as if the drainage were inserted in a lower space (i.e., biportal VATS), but with less discomfort.

“…However, they actually might be one of the main obstacles to ERAS [10]. In recent years, studies have been published in which drain types such as pigtail and pleural catheters were used instead of chest tubes [11]. Drainless surgeries are also being discussed to reduce pain and accelerate ERAS [12].…”
