| ObjectiveThe main non-surgical treatment options available for pneumothorax involve observation,oxygen supplementation,simple aspiration and tube thoracostomy,et al.Traditional chest tube causes considerable trauma in patients on account of large incision engendered during intubation.At present the application of 24~32 F silicon tube is a standard practice for patients with pneumothorax.With poor position controllability and solid material quality,traditional chest tube is prone to cause more pain and may injury the lung tissue due to improper operation during intubation process.On the other hand traditional chest tube is easy to be extruded and blocked in the thoracic cavity,thereby impedes the efficacy of closed thoracic drainage.The common diameter of pigtail catheter is about 8~14 F.Less pain,better tolerance and lower risk of lung injury may be achieved during intubation procedure,since pigtail catheter requires merely small incision due to a relative small diameter and soft material.Now it is usually utilized for the drainage of pneumothorax.However,there is no definite answer about the efficacy and safety of pigtail catheter in patients with pneumothorax compared to traditional chest tube yet.Thus our study is aim to evaluate the efficacy and safety of pigtail catheter versus chest tube in the treatment of patients with pneumothotax.MethodsClinical trails about pigtail catheter versus chest tube in the treatment of patients with pneumothorax were collected by searching databases of Pub Med,Cochrane Library,Embase,and Google Scholar up to November 26,2015.Then title,abstract and full text of included articles were read successively by researchers for document screening.Methodological index for non-randomized studies(MINORS)was used for methodological quality assessment of the final included literatures.Software Revman Manager 5.1 was employed for meta-analysis.Results4 literatures(1 randomized controlled trail,3 non-randomized controlled trails)containing a total of 522 patients(267 in pigtail catheter group and 255 in chest tube group)were included for analysis.The meta-analysis data revealed a significantly reduced postoperative duration of tube insertion in the pigtail catheter group compared to the chest tube group(weighted mean difference=-0.33,95% CI:-0.58~-0.07,P= 0.01).However,no statistical differences in success rate(relative ratio= 0.94,95% CI: 0.87~1.02,P= 0.13),postoperative hospital stay(weighted mean difference=-2.33,95% CI:-6.87~2.22,P= 0.32)and complications incidence(relative ratio= 0.73,95% CI: 0.29~1.86,P= 0.51)were found between the 2 groups.ConclusionCompared to common chest tube,the employment of pigtail catheter in the patients with pneumothorax significantly reduces the duration of tube insertion.Nevertheless,no statistically significant differences were discovered in success rate,postoperative hospital stay and the incidence of complications between the two corresponding groups.Thus pigtail catheter is competent in terms of closed thoracic drainage in patients with pneumothorax. |
