Objective To assess the effectiveness and safety of hand-suture vs. stapling anastomosis in esophagogastrostomy. Methods The following databases such as CBM (1978 to February 2012), VIP (1989 to February 2012), CNKI (1994 to February 2012), WanFang Data (1980 to February 2012), The Cochrane Library, PubMed (1966 to February 2012), EMbase (1974 to February 2012), and relevant webs of clinical trials were searched to collect the randomized controlled trials (RCTs) and quasi-RCTs about hand-suture vs. stapling anastomosis in the incidence of anastomotic leakage following esophagogastrostomy. Moreover, relevant references and grey literature were retrieved on web engines including Google Scholar and Medical Martix, and the Chinese periodicals e.g. Chinese Journal of Oncology were also handsearched. According to the inclusion and exclusion criteria, the literature, was screened, the data were extracted, and the quality of the included studies was assessed. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 9 RCTs involving 2 202 patients were included. The result of meta-analysis was as follows: the incidence of anastomotic leakage in the stapling anastomosis group was lower than that in the hand-suture anastomosis group (OR=0.43, 95%CI 0.26 to 0.71, Plt;0.01). Conclusion Stapling anastomosis is superior to hand-suture anastomosis in reducing the incidence of anastomotic leakage following esophagogastrostomy. For the limited quality and quantity of the included studies, this conclusion has to be further proved by more high-quality studies.
ObjectiveTo systematically evaluate the efficacy of neoadjuvant chemoradiotherapy or chemotherapy followed by surgery versus definitive chemoradiation in stage ⅢA-N2 non-small cell lung cancer (NSCLC).MethodsWe searched PubMed, EMbase, Web of Science and The Cochrane Library to collect clinical studies on the efficacy comparison between neoadjuvant chemoradiotherapy or chemotherapy followed by surgery and definitive chemoradiation in stage ⅢA-N2 NSCLC from inception to September 2022. The meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 9 studies (3 randomized controlled trials and 6 retrospective cohort studies) with 12 801 patients were included. The results of meta-analysis showed that there was no statistical difference in the progression-free survival rate between the inductive treatment followed by surgery (including lobectomy and pneumonectomy) and definitive chemoradiation (HR=0.99, 95%CI 0.86-1.15, P=0.91). Compared with definitive chemoradiation, the overall survival (OS) rate in the inductive treatment followed by surgery (including lobectomy and pneumonectomy) was lower (HR=1.24, 95%CI 1.09-1.42, P=0.001), while the OS rate in the inductive treatment followed by lobectomy was higher (HR=0.55, 95%CI 0.51-0.61, P<0.000 01). And the local recurrence rate in the inductive treatment followed by surgery was reduced (OR=0.44, 95%CI 0.36-0.55, P<0.000 01).ConclusionNeoadjuvant chemoradiotherapy or chemotherapy followed by lobectomy is superior to definitive chemoradiation in OS and it has a lower local recurrence rate, so lobectomy should be one of the multidisciplinary treatments for selected ⅢA-N2 NSCLC patients.
ObjectiveTo evaluate the efficacy of tubless therapy for pulmonary bulla resection under the concept of fast track surgery.MethodsWe retrospectively analyzed the clinical data of 45 patients (29 males and 16 females at an average age of 26.1 years) with pulmonary bullae in our hospital between January 2015 and December 2017. These patients were divided into two groups. Among them, 25 patients were treated with preoperative gastric tubes and catheters, tracheal intubation anesthesia and postoperative drainage tubes (a tube group). And 20 patients were treated with no preoperative gastric tube or catheter, sublaryngeal anesthesia and no postoperative drainage tube (a tubless group). ResultsThere was a statistical difference in postoperative pain index (2.60±1.14 vs. 5.16±1.24, P<0.001) and larynx complication (P=0.00) between the two groups. Shorter period of epidural analgesic tubes (1.40±0.50 d vs. 2.84±0.75 d, P<0.001), shorter operation and anesthesia time (15.00±2.59 min vs. 18.56±2.10 min, P<0.001; 95.30±4.38 min vs. 105.50±4.59 min, P<0.001), shorter hospital stay (9.45±1.66 d vs. 12.80±1.87 d, P<0.001), and less expense (20 245.96±1 113.02 yuan vs. 22 147.06±1 735.01 yuan, P<0.001) in the tubless group were found compared with the tube group. But there was no statistical difference in incidence of complication of lung (P=0.43) between the two groups.ConclusionTubless therapy in the treatment of pulmonary bulla resection can accelerate the postoperative recovery with shorter hospital stay and less expense, and is an advantageous treatment.
ObjectiveTo investigate the effects of two different oxygen therapies (oxygen time<4 h/d, oxygen flow>6 L/min versus oxygen time>4 h/d, oxygen flow<6 L/min) on conservative treatment of spontaneous pneumothorax by meta-analysis.MethodsThe following electronic databases as PubMed, The Cochrane Library, Web of Science, Chinese Biomedical Literature Database, WanFang Database and China National Knowledge Database were retrieved on computer for randomized controlled trials (RCTs) of comparing two different oxygen therapies (oxygen time<4 h/d, oxygen flow>6 L/min versus oxygen time>4 h/d, oxygen flow<6 L/min) on conservative treatment of spontaneous pneumothorax. The retrieval time was from inception of each database to December 2017. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies. Then data were analyzed by RevMan 5.3 software.ResultsA total of 4 RCTs involving 226 patients were included. The meta-analysis showed that compared with lower oxygen flow (oxygen time>4 h/d, oxygen flow<6 L/min), the higher oxygen flow (oxygen time<4 h/d, oxygen flow>6 L/min) could obviously decrease the degree of pulmonary compression after oxygen therapy for 5 days (MD=–2.81, 95%CI –4.18 to –1.44, P<0.05), shorten duration of hospital stay (MD=–3.26, 95%CI –6.05 to –0.47, P<0.05) and duration of recruitment maneuvers (MD=–2.78, 95%CI –5.27 to –0.28, P<0.05), but there was no significant difference in oxygen partial pressure after oxygen therapy for 5 days (MD=10.68, 95%CI –7.03 to 28.39, P=0.24).ConclusionThe higher oxygen flow (oxygen time<4 h/d, oxygen flow>6 L/min) can obviously decrease the degree of pulmonary compression after oxygen therapy for 5 days, shorten duration of hospital stay and duration of recruitment maneuvers, but the results are influenced by the number and quality of RCT.
ObjectiveTo investigate the clinical value of multidisclplinary team (MDT) in the application of non-small cell lung cancer (NSCLC). MethodsWe retrospectively analyzed the postoperative clinical data of 80 patients with NSCLC in the First Hospital of Lanzhou University between January 2014 and May 2018. There were 56 males, 24 females at age of 59±10 years. Forty five patients were performed lobectomy with conventional model, 35 patients were also performed lobectomy after MDT discussion. The clinical effect of the two groups was compared. ResultsCompared to conventional model, MDT can shorten operation time, intraoperative blood loss, postoperative chest drainage, catheterization time, complications, length of stay and hospital costs. But there was no significant difference in intraoperative transthoracotomy proportion, delayed wound healing and postoperative pulmonary leakage between the two groups. ConclusionThe efficacy of MDT in the surgical treatment of NSCLC is satisfactory. The MDT is valuable during operation, which reduces surgical trauma and accelerate patients’ recovery, and deserves the clinical promotion.
ObjectiveTo investigate the effect of multidisciplinary team (MDT) on perioperative complications and clinical efficacy of patients who were receiver radical operation to treat lung cancer by video-assisted thoracoscopic surgery (VATS). MethodsEighty patients in the Thoracic Surgery Department of First Hospital of Lanzhou University from December 2017 to February 2019 who were diagnosed lung cancer were divided into two groups. Forty patients in the MDT group were treated with MDT discussion. The control group consisted of 40 patients who were treated without MDT discussion. The incidence of postoperative complications and clinical efficacy were compared between the two groups . ResultsThere was no statistical difference in incision infection, atelectasis, pleural effusion and pulmonary leakage between the two groups. However, the incidence of postoperative pulmonary infection (5% vs. 20%, P=0.043) and the overall postoperative complications (17.5% vs. 42.5%, P=0.015) in the MDT group was lower than that in the control group with a statistical difference. In the MDT group, the operative time (140.3±8.0 min vs. 148.8±6.8 min, P<0.001), intraoperative bleeding ( 207.8±19.4 mL vs. 222.0±28.3 mL, P=0.010), lymph node dissection number (25.1±6.2 vs. 20.1±7.0, P=0.001), postoperative drainage (273.0±33.5 mL vs. 24.0±52.5 mL, P<0.001), drainage duration (81.9±6.1 h vs. 85.3±8.1 h, P=0.039), pain on the first day after surgery (4.6±0.7 vs. 5.4±0.7), P<0.001), pain on the second day (2.5±0.7 vs. 3.0±0.8, P=0.002), pain on the third day (1.1±0.8 vs. 1.5±0.6, P=0.014), postoperative activity time (40.7±6.7 h vs. 35.3±7.1 h, P<0.001), postoperative recovery time (6.8±0.9 d vs. 7.4±0.7 d, P=0.003), patient satisfaction (8.1±1.4 vs. 7.2±2.0, P=0.020) were significantly better than those of the control group with statistical differences. But there was no statistical difference in the conversion to thoracotomy between the two group. ConclusionMDT discussion can reduce the surgical risk and postoperative complications, improve the clinical efficacy and accelerate the postoperative rehabilitation of patients, which has a good clinical significance.
ObjectiveTo explore the safety, feasibility and superiority of tubeless video-assisted thoracoscopic surgery (VATS) in the treatment of spontaneous pneumothorax.MethodsWe retrospectively analyzed the clinical data of 38 patients with primary spontaneous pneumothorax treated in our hospital from February 2017 to July 2018. Tubeless bullectomy was performed in 18 patients, including 11 males and 7 females, aged 14.3±1.5 years. Twenty patients underwent conventional thoracoscopic bullae resection, including 12 males and 8 females, aged 14.5±1.7 years. The clinical effectiveness was compared.ResultsAll the 38 patients completed the operation successfully under the single-port thoracoscopy, without the transfer of intubation and secondary surgery. Operation time (67.3±13.3 min vs. 81.4±13.4 min, P=0.002), preoperative anesthesia time (14.2±2.6 min vs. 18.5±2.6 min, P=0.000), postoperative anesthesia recovery time (17.1±2.6 min vs. 26.5±5.0 min, P=0.000), visual simulation score of postoperative pain (2.3±0.9 vs. 5.2±1.0, P=0.000), postoperative activity time (1.3±0.4 d vs. 2.9±0.6 d, P=0.000), postoperative hospitalization time (2.9±0.8 d vs. 5.6±1.3 d, P=0.000), hospitalization cost (35.0±6.0 kyuan vs. 59.0±10.0 kyuan, P=0.000) were better in the control group. There was no significant difference in intraoperative blood loss (73.2±4.6 mL vs. 73.9±4.1 mL) and postoperative lung revascularization time (29.3±2.4 h vs. 29.7±2.5 h) between the two groups (P>0.05).ConclusionCompared with traditional thoracoscopic bullectomy, tubeless VATS technique is safe and reliable in the treatment of spontaneous pneumothorax, with mild pain and quick recovery, in line with the concept of fast track surgery and worthy of clinical promotion.
ObjectiveTo explore the clinical effect of tubeless 3 mm ultra-fine thoracoscope combined with needle electrocoagulation hook thoracic sympathicotomy in the treatment of primary palmar hyperhidrosis. MethodsThe clinical data of 77 patients with primary palmar hyperhidrosis who underwent surgery in the First Hospital of Lanzhou University from September 2017 to July 2021 were retrospectively analyzed, including 50 males and 27 females, with an average age of 23.60±5.60 years. A total of 36 patients were treated with tubeless 3 mm ultra-fine thoracoscopic electrocoagulation hook thoracic sympathicotomy (an observation group), and 41 patients were treated with conventional thoracoscopic thoracic sympathicotomy (a control group). The baseline data, perioperative data and the results of 12 hours after operation were compared between the two groups. ResultsAll the 77 patients completed the operation successfully, no conversion to thoracotomy, no intraoperative bleeding, and no conversion to endotracheal intubation in the observation group. In the observation group, the time of anesthesia before operation [19.00 (17.00, 23.75) min vs. 25.00 (21.00, 27.00) min, P=0.001] and postoperative hospital stay [2.00 (1.00, 2.00) d vs. 2.00 (1.00, 3.00) d, P=0.012] were shorter than those in the control group. The operation time [22.50 (21.00, 25.75) min vs. 26.00 (23.50, 28.50) min, P=0.001], intraoperative blood loss [5.00 (2.25, 5.00) mL vs. 6.00 (5.00, 10.00) mL, P=0.003], postoperative pain index [2.00 (1.00, 2.00) vs. 3.00 (2.00, 3.00), P=0.001], hospitalization cost (14 246.58±879.28 yuan vs. 15 085.90±827.15 yuan, P<0.001) and postoperative inflammation index: white blood cell count [(12.96±2.32)×109/L vs. (14.47±2.05)×109/L, P=0.003], percentage of neutrophils (76.31%±5.40% vs. 79.97%±7.12%, P=0.014) were significantly lower or less than those in the control group. There was no significant difference in the incidence of major postoperative complications or adverse consequences between the two groups (P>0.05). In the evaluation of 12 hours after operation, the time of getting out of bed [2.00 (1.00, 2.00) h vs. 2.00 (2.00, 3.00) h, P=0.017], the time of drinking water after operation [1.50 (1.00, 2.00) h vs. 2.00 (1.00, 3.00) h, P=0.005], and the heart rate (80.25±14.42 bpm vs. 91.07±15.08 bpm, P=0.002), the incidence of dizziness, nausea and other uncomfortable symptoms (5.6% vs. 25.0%, P=0.040) at 12 hours after operation were shorter or lower than those in the control group. There was no significant difference in blood oxygen saturation (non-inhaled oxygen state) 12 hours after the operation between the two groups [97.00% (95.25%, 98.00%) vs. 97.00% (96.00%, 98.00%), P=0.763]. ConclusionCompared with conventional thoracoscopic thoracic sympathicotomy, tubeless 3 mm ultra-fine thoracoscopic electrocoagulation hook thoracic sympathicotomy can significantly shorten the operation time, reduce postoperative pain and promote postoperative recovery, in line with the concept of accelerated rehabilitation surgery and minimally invasive surgery, and is worth popularizing in clinical practice.
Objective To discuss the safety, feasibility and advantages of tubeless trans-subxiphoid thoracoscopic surgery in anterior mediastinal tumor resection. Methods A total of 32 patients suffering anterior mediastinal tumor were enrolled, including 17 patients (8 males and 9 females) with average age of 31.8±8.4 years who had been performed tubeless trans-subxipohoid tharcoscopic surgery and 15 patients (8 males and 7 females) with average age of 31.1±9.2 years who had been performed traditional trans-subxipohoid tharcoscopic surgery. The differences of surgical duration, the lowest intraoperative arterial oxygen saturation (SaO2), postoperative awaking time, postoperative pain visual analogue score (VAS), postoperative pulmonary recruitment time, duration of postoperative hospital stay and hospitalization cost were analyzed. Results Postoperative awaking time (18.5±1.8 min vs. 28.9±4.2 min, P=0.000), postoperative VAS (1.6±0.6 vs. 3.5±7.4, P=0.000), duration of postoperative hospital stay (2.5±7.2 d vs. 4.3±1.1 d, P=0.000) and hospitalization cost (3.2±1.1 ten thousand RMB vs. 4.9±1.1 10 ten thousand RMB, P=0.000) in the tubeless group were better than those in the control group. There was no significant difference in surgical duration (51.7±6.5 min vs. 55.1±8.5 min), the lowest intraoperative SaO2 (98.5%±0.9% vs. 98.1%±0.8%), postoperative pulmonary recruitment time (33.9±12.2 d vs. 38.4±15.2 d, P>0.05) between the two groups.Conclusion Tubeless trans-subxiphoid thoracoscopic surgery is safe, feasible and advanced in anterior mediastinal tumor resection.
In this study, we aim to investigat the effect of microgravity on osteoblast differentiation in osteoblast-like cells (MC3T3-E1). In addition, we explored the response mechanism of nuclear factor-kappa B (NF-κB) signaling pathway to " zero-g” in MC3T3-E1 cells under the simulated microgravity conditions. MC3T3-E1 were cultured in conventional (CON) and simulated microgravity (SMG), respectively. Then, the expression of the related osteoblastic genes and the specific molecules in NF-κB signaling pathway were measured. The results showed that the mRNA and protein levels of alkaline phosphatase (ALP), osteocalcin (OCN) and type Ⅰ collagen (CoL-Ⅰ) were dramatically decreased under the simulated microgravity. Meanwhile, the NF-κB inhibitor α (IκB-α) protein level was decreased and the expressions of phosphorylation of IκB-α (p-IκB-α), p65 and phosphorylation of p65 (p-p65) were significantly up-regulated in SMG group. In addition, the IL-6 content in SMG group was increased compared to CON. These results indicated that simulated microgravity could activate the NF-κB pathway to regulate MC3T3-E1 cells differentiation.
