ObjectiveTo evaluate the feasibility and clinical effect of controlled hypotension in video-assisted thoracoscopic surgery (VATS) for subcarinal lymph node dissection in patients with lung cancer.MethodsWe analyzed the clinical data of 53 non-small cell lung cancer (NSCLC) patients undergoing VATS with controlled systolic blood pressure while dissecting the subcarinal lymph node from September to October 2016 in our department (a treatment group, including 31 males and 22 females with an average age of 53.20±8.80 years ranging 43-68 years). We selected 112 NSCLC patients undergoing VATS without controlled systolic blood pressure while dissecting the subcarinal lymph node from January to August 2016 in our department (a contol group, including 67 males and 45 females with an average age of 54.32±7.81 years ranging 39-73 years). The clinical data of both groups were compared.ResultsThe operation time and blood loss of the treatment group were less than those of the control group (177.6±39.4 min vs. 194.3±47.8 min, 317.9±33.6 ml vs. 331.2±38.7 ml, P<0.05). The duration of subcarinal lymph node dissection and total duration of lymph node dissection of the treatment group were also less than those of the control group (10.5±4.3 min vs. 13.6±5.2 min, 37.7±7.5 min vs. 48.7±6.4 min, P<0.001). The thoracic drainage at postoperative days 1, 2, 3 and total drainage volume, duration of tube placement and hospital stay of the treatment group were less than those of the control group (P<0.05). Whereas the postoperative complications of the two groups did not differ significantly (P>0.05).ConclusionControlled hypotension reduces the difficulty of dissecting subcarinal lymph nodes and the risk of bleeding, and produces less drainage volume, which is safe and effective.
Lung adenocarcinoma has become the most common type of lung cancer. According to the 2015 World Health Organization histological classification of lung cancer, invasive lung adenocarcinoma can be divided into 5 subtypes: lepidic, acinar, papillary, solid, and micropapillary. Relevant studies have shown that the local lobectomy or sublobectomy is sufficient for early lepidic predominant adenocarcinoma, while lobectomy should be recommended for tumors containing micropapillary and solid ingredients (≥5%). Currently, the percentage of micropapillary and solid components diagnosed by frozen pathological examination is 65.7%, and the accuracy of diagnosis is limited. Therefore, to improve the accuracy of diagnosis, it is necessary to seek new methods and techniques. This paper summarized the characteristics and rapid diagnosis tools of early lung adenocarcinoma subtypes.
Objective To compare the safety of manual anastomosis and mechanical anastomosis after esophagectomy by meta-analysis. MethodsThe randomized controlled trials (RCTs) about manual anastomosis and mechanical anastomosis after esophagectomy were searched from PubMed, EMbase and The Cochrane Library from inception to January 2018 by computer, without language restrictions. Two authors according to the inclusion and exclusion criteria independently researched literature, extracted data, evaluated bias risk and used R software meta package for meta-analysis. Results Seventeen RCTs were enrolled, including 2 159 patients (1 230 by manual anastomosis and 1 289 by mechanical anastomosis). The results of meta-analysis showed that: (1) there was no significant difference in the incidence of anastomotic leakage between mechanical and manual anastomosis (RR=1.00, 95%CI 0.67–1.48, P=0.181); (2) no significant difference was found in the 30-day mortality (RR=0.95, 95%CI 0.61–1.49, P=0.631); (3) compared with manual anastomosis, the mechanical anastomosis group may increase the risk of anastomotic stenosis (RR=0.74, 95%CI 0.48-1.14, P<0.001). Conclusion Esophageal cancer surgery using a linear or circular stapler can increase the incidence of anastomotic stenosis after surgery. There is no significant difference in the anastomotic leakage and 30-day mortality between manual anastomosis, linear stapler and circular stapler.
ObjectiveTo investigate the effect of perioperative allogeneic blood transfusion on the prognosis of patients with non-small cell lung cancer (NSCLC).MethodsThe databases including PubMed, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM were searched for literature about the effects of perioperative allogeneic blood transfusion on the prognosis of patients with NSCLC from the inception to May 2020. Two authors independently screened the literature, extracted and cross-checked data, and negotiated to resolve differences in opinions. Review Manager V5.3 (Cochrane Collaboration, Oxford, UK) software was used for data analysis.ResultsA total of 15 articles were included, including 5 897 patients. There were 1 649 patients in the trial group and 4 248 patients in the control group. The results of meta-analysis showed that the overall survival of the control group was significantly higher than that of the trial group (OR=0.58, 95%CI 0.47-0.70, P<0.000 01). The disease-free survival of the control group was significantly higher than that of the trial group (OR=0.43, 95%CI 0.36-0.52, P<0.000 01). The recurrence rate of the control group was significantly lower than that of the trial group (OR=1.85, 95%CI 1.34-2.55, P=0.000 2).ConclusionPerioperative allogeneic blood transfusion has adverse effects on the recurrence and survival of patients with NSCLC.
