ABSTRACT
Objective:To investigate the correlation between the muscle mass loss and severe postoperative pulmonary complications(PPC)in elderly patients with non-small cell lung cancer(NSCLC).Methods:Elderly patients with NSCLC undergoing lobectomy at the Lung Cancer Institute and the Department of Thoracic Surgery of Guangdong Provincial People's Hospital were recruited from Feb.2019 to Dec.2019.Data of the body composition, lung function, respiratory muscle strength test, cardiopulmonary exercise test were collected before operation.All patients were grouped into two groups: with versus without severe PPC at 30 d after operation.The differences of the above parameters were compared between the two groups.A multiple logistic regression analysis was used to analyze the risk factors for severe PPC.Results:In this study, 120 elderly NSCLC patients undergoing lobectomy were recruited, All evaluations were completed in 113 patients(aged 68.13±7.01 years)in whom, 21(18.58%, 21/113)patients had serious PPC.Compared with patients without PPC, patients with severe PPC had a lower appendicular skeletal muscle mass index(ASMI)(5.67±0.90 kg/m 2vs.7.71±1.40 kg/m 2, t=3.900, P=0.001), a lower forced expiratory volume in 1 second(FEV 1)(1.85±0.40 L vs.2.12±0.57 L, t=2.412, P=0.027), a lower maximal mid-expiratory flow(MMF)(1.40±0.69 L/s vs.2.11±1.09 L/s, t=2.502, P=0.021), a lower maximum inspiratory pressure(Pimax)(55.13±32.52 cmH 2O vs.64.71±20.60, t=0.778, P=0.047, 1 cmH 2O=0.098 kPa), a lower maximal oxygen consumption(Vo 2max)(1.14±0.41 L/min vs.1.40±0.34 L/min, t=0.779, P=0.046), a lower peak O 2 consumption(Vo 2max@kg)(20.00±1.91 L·min -1·kg -1vs.22.33±2.37 L·min -1·kg -1, t=0.813, P=0.041). Multiple logistic regression analysis showed that in addition to FEV 1( OR=2.824, 95% CI: 1.127-5.158, P=0.001)and Vo 2max@kg( OR=3.149, 95%CI: 1.829-6.592, P<0.001), ASMI was also an independent risk factor for serious PPC( OR=1.919, 95% CI: 1.604-3.466, P=0.006), in which the best cut-off value was 6.295 kg/m 2, the sensitivity and specificity were 0.816 and 0.818 respectively, and the area under the receiver operating characteristic(ROC)curve(AUC)was 0.887(95% CI: 0.793-0.981, P<0.0001). Conclusions:Muscle mass loss can increase the risk for the occurrence of severe PPC within 30 days after lobectomy in elderly patients with NSCLC.
ABSTRACT
@#Giant thoracic tumor is currently one of the diagnostic and therapeutic challenges of thoracic surgery, with no established guideline or standard for diagnosis and treatment. The quality control of individualized surgical strategy and perioperative management with multi-disciplinary participation is the key to ensure the safety and improve the prognosis of patients. Based on the clinical experience of our institution and others, we hereby discussed and summarized the basic principles, surgical strategies and perioperative management of giant thoracic tumor, aiming to provide a reference of quality control.
ABSTRACT
Objective To study the influence of the minimal invasive Nuss procedure on the pulmonary function of post-operative pectus excavatum patients. Methods Conduct retrospective analysis on the data from 676 pectus excavatum patients who were treated by the minimal invasive Nuss procedure from August 2006 to November 2014. Wherein 182 cases have com-plete preoperative and postoperative pulmonary-function data of one year, three years. These cases were divided into 3 groups according to the age, namely, children group( from 6 to 12 years old, 34 cases) , adolescents group( from 13 to 18 years old, 80 cases) , adults group( above 18 years old, 68 cases) , among which there were 71 cases with pulmonary function data of 1 year after removal of steel plate, they were divided into 3 groups in the same way,namely, children group(20 cases), adoles-cents group(22 cases), adults group(29 cases) . To compare and analyze the pulmonary function indicatrix of patients with dif-ferent ages in preoperative stage, 1 year, 3 years postoperative stages and 1 year after dismantling the steel plate stage, and to investigate the influence of the minimal invasive Nuss procedure on the postoperative lung function. Results The pulmonary function indicatrix in preoperative stage, 1 year, 3 years postoperative stages of the children group did not have significant difference(P>0. 05); the FVC, FEV1 indicatrix of adolescents and adults groups declined after operation in 1 year and 3 years compared with the preoperative stage(P<0. 05), FEF 25% -75%, FEF 50%, FEF75% were improved after operation in 1 year and 3 years compared with the preoperative stage(P<0. 05);the pulmonary function indicatrix of three age groups in the 1 year after dismantling the steel plate stage had all improved, in which the pulmonary function indicatrix of the children group improves most significantly(P<0. 05). Conclusion After the minimal invasive Nuss procedure before the plate dis-mantling process, the pulmonary function of children patients remains to be similar. Partial ventilatory function was damaged in the adolescents and adults patients. After the plate dismantling process, the pulmonary function indicatrix of each age group hasimproved in different degrees. Improvement effect is the most significant in patients below the age of 12.
ABSTRACT
Objective The Nuss procedure is a minimally invasive pectus repair.The aim of this study was to explore the changes in quality of life in patients who underwent a Nuss procedure.Methods 96 patients,who underwent a Nuss procedure in our institution,were interviewed at preoperation,1 year after operation with the bar in place,and before the planned bar removal.The Nuss Questionnaire modified by George Krasopoulos et al,which evaluates psychosocial and physical well-being,was independently used by patients.Results Most of the scoring of the individual questions and the total score of individual patients revealed a significant improvement,both in preoperation vs.1 year after operation and 1 year after operation vs.before the planned bar removal.Conclusion The Nuss procedure has been shown to improve the quality of life in patients with pectus excavatum deformity in the short term.
ABSTRACT

ABSTRACT
Background and purpose: Three-incision esophagectomy for patients with esophageal cancer has been increasingly used, but the incidence of either postoperative anastomotic leak or stricture is higher than that in intrathoracic gastroesophageal anastomosis. The purpose of this study was to investigate the clinical effects of the side-to-side stapled cervical gastroesophageal anastomosis in preventing anastomotic leak and stricture after three-incision esophagectomy. Methods: One hundred and twenty-seven patients undergoing three-incision esophagectomy for esophageal cancer with gastric replacement were reviewed. A side-to-side stapled cervical gastroesophageal anastomosis was performed in 71 cases and manually sewn anastomosis in 56 cases. The incidence of postoperative anastomotic leak and stricture was compared between these two groups and the results were statistically analyzed using SPSS11.0 soft.Results: Anastomotic leakage was noted in seven patients (9.9%) in the stapler group and fourteen patients (25.0%) in the manually sewn group (P=0.04). After the operation two patients (2.8%) in the stapler group and nine patients (16.1%) in the manually sewn group developed a benign esophageal stricture (P=0.02).The incidence of either postoperative anastomotic leak or stricture in cases of the stapler group was significantly lower than that in the manually sewn group (P<0.05). Conclusion: Construction of the cervical esophagogastric anastomosis with a side-to-side stapled technique provides a larger luminal diameter which significantly reduces the incidence of postoperative anastomotic strictures. The surgery also greatly reduces the incidence of anastomotic leaks and strictures, so it could be used as an alternative strategy for cervical esophagogastric anastomosis after esophagectomy for esophageal cancer
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the bacterial epidemiology in our department in recent years, so as to provide assistance to the clinical management of burn patients.</p><p><b>METHODS</b>A retrospective analysis was carried out with 345 bacterial cultures from burn wound and drug-sensitivity results in 784 burn patients during 1993 to 1999 in our department.</p><p><b>RESULTS</b>(1) Among all the bacteria, gram negative (G(-)) bacilli accounted for 56.8%, while gram positive (G(+)) cocci and fungi in 3.8%. (2) Among all the G(+) cocci, 65.4% were Staphylococcus aureus, in which MRSA was identified in 53.9% during 1993 - 1999 and in 64.3% during 1998 - 1999. Pseudomonus aeruginosa accounted for 37.2% of all G(-) bacilli. (3) The 3rd generation of cephalosporins shew excellent anti-bacterial capabilities, but the bacterial resistance to them increased significantly. (4) MRSA was very sensitive to both vancomycin and norvancomycin with no report of antibiotic resistance to them.</p><p><b>CONCLUSION</b>G(-) bacilli were still predominant bacteria in our burn department when compared to G(+) cocci. The 3rd generation cephalosporins are the routine antibiotics for the present. But resistant bacteria are on the increase. There are also more and more MRSAs isolated from burn wounds. For this, vancomycin and norvancomycin should be preferably used.</p>
