The aim of this study was to evaluate the efficacy of the Thopaz system, a new drainage system in management of general thoracic surgery, based on a review of our clinical practice and a comparison of the utility of the Thopaz device compared with a standard drainage system.
A review of 540 thoracic surgeries at our hospital was performed. These cases were divided into 275 treated with the Thopaz system from April 2014 to March 2015 and 265 treated with a standard system from April 2013 to March 2014. The characteristics of patients and outcomes after surgery were compared in these 2 groups.
The characteristics of the patients were similar in the 2 groups. Outcomes after surgery, including types of operation, period of chest tube placement, chest tube reinsertion rate and clamping test rate also did not differ significantly between the groups.
The non-inferiority of the Thopaz system compared to a standard system was verified statistically. With advantages of providing objective data as a small portable system, in addition to the quietness of the unit and the ease of setup and operation, Thopaz system is likely to become mainstream in postoperative management in general thoracic surgery.
本研究旨在通过回顾我们的临床实践，并比较Thopaz系统与标准引流系统的效用，评估一种用于普通胸外科手术管理的新型引流系统Thopaz系统的疗效。
对我院540例胸外科手术进行了回顾性研究。这些病例分为两组，2014年4月至2015年3月期间使用Thopaz系统治疗的有275例，2013年4月至2014年3月期间使用标准系统治疗的有265例。比较这两组患者的特征和术后结果。
两组患者的特征相似。两组术后结果，包括手术类型、胸管留置时间、胸管重新插入率和夹闭试验率，差异均无统计学意义。
Thopaz系统与标准系统相比的非劣效性得到了统计学验证。Thopaz系统作为一种小型便携式系统，具有提供客观数据的优点，此外该装置安静且易于设置和操作，有望成为普通胸外科术后管理的主流。
