The question addressed was 'Is video-assisted thoracoscopic surgery comparable with thoracotomy in perioperative and long-term survival outcomes for patients with non-small cell lung cancer following neoadjuvant therapy intended for anatomical lung resection?'. Altogether 655 papers were found using the reported search, of which 12 studies represented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type and relevant outcomes and results of these papers are tabulated. Almost all of the enrolled cohort studies reported that video-assisted thoracoscopic surgery (VATS) was comparable with thoracotomy in negative surgical margin rate, postoperative mortality, complication rate, overall survival and disease-free survival. Moreover, 7 studies found patients in the VATS group had a significantly shorter hospital stay. Furthermore, in these well-matched cohort studies (6 studies), it still held true that VATS was comparable with thoracotomy in long-term prognosis with enhanced recovery. However, the issue regarding surgical radicality and intraoperative conversion to thoracotomy still should be noted carefully among these patients receiving VATS surgery because all the current available evidence was retrospective based on relatively small sample sizes. Nevertheless, thoracic surgeons should not consider VATS inferior to thoracotomy for patients after neoadjuvant treatment. VATS surgery could be an alternative for selected patients with locally advanced but relatively small, peripheral, fewer positive N2 lymph nodes and non-squamous NSCLC intended for anatomic lung resection.</p>","PeriodicalId":13621,"journal":{"name":"Interactive cardiovascular and thoracic surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/6b/fc/ivac271.PMC9686345.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10383206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Cerebral protection in aortic arch surgery: systematic review and meta-analysis.","authors":"Vivek Patel,&nbsp;Vicente Orozco-Sevilla,&nbsp;Joseph S Coselli","doi":"10.1093/icvts/ivac270","DOIUrl":"https://doi.org/10.1093/icvts/ivac270","url":null,"abstract":"Cerebral protection during aortic arch surgery is based on reduction in metabolic demand (hypothermia) and delivery of metabolic nutrients (antegrade or retrograde cerebral perfusion techniques) to reduce the risk of stroke [1]. The risk of neurologic deficit remains 5–10%, despite the advent of adjunctive cerebral perfusion techniques in the 1990s [1, 2]. In a noble effort to determine the most effective type of adjunctive cerebral perfusion, Abjigitova et al. conducted the largest systematic review on this topic, a meta-analysis of 222 studies involving 43 720 patients [3]. The authors conclude that unilateral antegrade cerebral perfusion (ACP) had a lower mortality (6.6%) and stroke rate (4.8%), whereas bilateral ACP (9.1% mortality, 7.3% stroke), retrograde (7.8%, 6.4%) and deep hypothermic circulatory arrest without adjunctive perfusion (9.2%, 6.3%) had higher rates of mortality and stroke. However, these conclusions must be tempered with the following considerations. The data are diverse because it is mostly from observational studies, which include multiple procedures (hemiarch, total arch), indications for surgery (dissection, aneurysms) and experience (smaller and larger centres across the world). Importantly, there is no consensus on the criteria for selecting antegrade, bilateral antegrade, retrograde or deep hypothermic circulatory arrest without cerebral perfusion. Confounding considerations (pre-existing cerebrovascular anatomy, history of stroke, anticipated complexity of the procedure) may have led to the selection of 1 cerebral perfusion technique over another. The lowest temperature and total time of cerebral perfusion for each technique were also incomplete across the studies. Unfortunately, without this level of granularity, it becomes quite difficult to conclusively determine if 1 technique is indeed superior to another. Accordingly, the authors are careful to not directly compare 1 technique to another. Nonetheless, the meta-analysis adds to the literature by correlating the findings of similar studies by Angeloni et al., Lou et al. and our group [4–6]. We applaud the authors for reviewing 222 studies with 43,720 patients to gain insights into the trends regarding this important topic and providing real world data for the currently used techniques of cerebral perfusion. Any type of cerebral perfusion (antegrade or retrograde) is preferable compared to having no cerebral perfusion. There is a trend towards less use of retrograde cerebral perfusion [3]. Unilateral ACP is a relatively simple, reproducible technique which has gained popularity. However, since 6–17% of the adult population has an incomplete circle of Willis, our preferred technique is bilateral ACP, especially when a circulatory arrest time of greater than 30 min is anticipated due to the complexity of the procedure, i.e. total arch replacement [6]. Notably, Angeloni et al. [4] and Preventza et al.
