Safety and feasibility of a novel chest tube placement in uniportal video‐assisted thoracoscopic surgery for non‐small cell lung cancer

BACKGROUND: The type and placement of chest tube for patients undergoing uniportal video‐assisted thoracoscopic lobectomy remains controversial. The aim of this study was to assess the efficacy and safety of a novel technique in which a pigtail catheter was used alone as the chest tube and placed near the incision for chest drainage after uniportal video‐assisted thoracoscopic lobectomy and extended lymphadenectomy. METHODS: A total of 217 patients undergoing uniportal video‐assisted thoracoscopic lobectomy were retrospectively reviewed and divided into two groups. In group A, a 12‐Fr pigtail catheter with several side ports was placed next to the uniportal wound. In group B, a conventional 20‐Fr chest tube was placed through the uniportal wound itself. Postoperative complications related to chest tube placement and patients' subjective satisfaction were compared between the two groups. Postoperative pain management effect and other clinical outcomes such as duration of chest drainage and postoperative stay were also compared. RESULTS: There were 112 patients in group A and 105 patients in group B. A significantly lower incidence of wound complications was found in group A postoperatively (p = 0.034). The pain score on coughing in group A was significantly lower than that in group B on postoperative day two (POD2) (p = 0.021). There was no significant difference of other clinical outcomes such as duration of chest drainage and postoperative stay as well as major complications between the two groups. CONCLUSION: Placing a 12‐Fr pigtail catheter alone next to the uniportal wound for chest drainage might be effective and safe after uniportal video‐assisted thoracoscopic lobectomy and extended lymphadenectomy.
