ObjectiveTo discuss the safety and feasibility of no chest tube (NCT) after thoracoscopic pneumonectomy.MethodsThe online databases including PubMed, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), WanFang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to October 2020 to collect the research on NCT after thoracoscopic pneumonectomy. Two reviewers independently screened the literature, extracted the data, and evaluated the quality of the included studies. The RevMan 5.3 software was used for meta-analysis.ResultsA total of 17 studies were included. There were 12 cohort studies and 5 randomized controlled trials including 1 572 patients with 779 patients in the NCT group and 793 patients in the chest tube placement (CTP) group. Meta–analysis results showed that the length of postoperative hospital stay in the NCT group was shorter than that in the CTP group (SMD=–1.23, 95%CI –1.59 to –0.87, P<0.000 01). Patients in the NCT group experienced slighter pain than those in the CTP group at postoperative day (POD)1 (SMD=–0.97, 95%CI –1.42 to –0.53, P<0.000 1), and POD2 (SMD=–1.10, 95%CI –2.00 to –0.20, P=0.02), while no statistical difference was found between the two groups in the visual analogue scale of POD3 (SMD=–0.92, 95%CI –1.91 to 0.07, P=0.07). There was no statistical difference in the 30-day complication rate (RR=0.93, 95%CI 0.61 to 1.44, P=0.76), the rate of postoperative chest drainage (RR=1.51, 95%CI 0.68 to 3.37, P=0.31) or the rate of thoracocentesis (RR=2.81, 95%CI 0.91 to 8.64, P=0.07) between the two groups. No death occurred in the perioperative period in both groups.ConclusionIt is feasible and safe to omit the chest tube after thoracoscopic pneumonectomy for patients who meet the criteria.
ObjectiveTo systematically evaluate the effects of non-vitamin K antagonist oral anticoagulants (NOAC) and vitamin K antagonists (VKA) on postoperative anticoagulation in patients undergoing transcatheter aortic valve implantation (TAVI) with combined high-risk atrial fibrillation (AF). MethodsAll clinical research literature on NOAC and VKA in TAVI patients with high-risk AF was collected using computer searches of PubMed, EMbase, The Cochrane Library, CNKI, VIP, and SinoMed. The retrieval schedule was from inception to January 2023. The Newcastle-Ottawa Scale (NOS) was utilized to provide an assessment of the quality of the included literature. Meta-analysis was performed by applying RevMan 5.4 software to the studies that met the quality criteria. ResultsA total of 24 592 patients were incorporated in 7 eligible papers for meta-analysis. Patients with NOAC had a significantly lower risk of all-cause mortality compared with TAVI patients with combined high-risk AF who had VKA [RR=0.74, 95%CI (0.58, 0.94), P=0.01]. During the first year of follow-up, no apparent difference in all-cause mortality was observed between the two groups [RR=0.57, 95%CI (0.17, 1.88), P=0.35]. After a year of following up on patients treated with VKA, all-cause mortality was higher in the group treated with NOAC, and the difference was statistically meaningful [RR=0.73, 95%CI (0.57, 0.95), P=0.02]. Patients in both groups had early stroke [RR=0.50, 95%CI (0.19, 1.28), P=0.15], follow-up stroke [RR=1.04, 95%CI (0.88, 1.22), P=0.64] and bleeding [RR=0.94, 95%CI (0.73, 1.21), P=0.61], severe or life-threatening hemorrhage [RR= 0.80, 95%CI (0.49, 1.31), P=0.38], and acute kidney injury [RR=0.51, 95%CI (0.16, 1.59), P=0.24] were all non-statistically significant differences. ConclusionCompared with the application of VKA, postoperative anticoagulation with NOAC in TAVI patients with combined high-risk AF may reduces all-cause mortality in patients and may yield additional benefit especially in long-term anticoagulation.
