  • Survival analysis of stage ⅠA non-small cell lung cancer patients with lobectomy and sublobar resection

    Objective To make a survival analysis for the stage ⅠA non-small cell lung cancer patients who underwent lobectomy, segmentectomy or wedge resection and to discuss whether the segmentectomy and wedge resection can be used as a conventional operation. Methods The clinical data of 474 patients diagnosed with ⅠA non-small cell lung cancer from January 2012 to June 2015 in the First Affiliated Hospital of China Medical University were retrospectively anlyzed. There were 192 males and 282 females with a mean age of 60 years. Their sex, age, histological type, tumor size, surgical pattern, smoking, drinking, survival rate, disease-free survival rate, recurrence rate were compared. Results Disease-free survival rate of patients with wedge resection was significantly lower than that of the patients undergoing lobectomy and segmentectomy (P<0.05). When tumor diameter≤19 mm, the disease-free survival rate of patients with wedge resection was lower than that of patients with lobectomy (P=0.006) and segmentectomy (P=0.065). Disease-free survival rate of patients with tumor diameter of 20-<30 mm was significantly lower than that of patients with tumor diameter≤19 mm (P=0.026). Excluding patients with wedge resection, disease-free survival of the patients with lobectomy and segmentectomy and tumor diameter of 20-<30 mm was significantly lower than that of patients with tumor diameter≤19 mm (P=0.036). Patients with wedge resection had significant higher risk of local recurrence than that of patients undergoing lobectomy (P<0.001) and segmentectomy (P=0.002). Conclusion StageⅠA non-small cell lung cancer patients undergoing segmentectomy can obtain approximate survival and disease-free survival rate compared with those with lobectomy, especially in patients with tumor diameter≤19 mm. Pulmonary wedge resection as surgical treatment of lung cancer patients must be selected carefully according to the actual situation and surgical purposes.

  • Thrombolytic Therapy of Acute Deep Vein Thrombosis of Lower Extremity(Report of 126 Cases)

    Objective To explore the results of thrombolytic therapy of acute deep vein thrombosis of lower extremity. Methods The clinical data of 126 patients with acute deep vein thrombosis of lower extremity treated conservatively from Dec.1999 to Feb.2004 were analyzed retrospectively. Results All patients were divided into three groups: 26 of central, 33 of surrounding and 67 of combined by Doppler sonography. Combined medication was adopted in all cases, in which 85 cases (67.5%) were clinically cured, 34 cases (27.0%) had good results, and 5 cases (4.0%) recovered partially. Two cases (1.6%) didn’t get better. The total effective rate was 98.4% (124/126). Conclusion Most patients with acute deep vein thrombosis of lower extremity can get satisfied results with conservative treatment including thrombolysis and anticoagulation. Early diagnosis and appropriate medication are crucial.

  • Maze Ⅳ in the treatment of heart valve disease with persistent atrial fibrillation in elderly patients: A cohort study

    ObjectiveTo investigate the clinical effect of Maze Ⅳ in the treatment of elderly patients with valvular heart disease and persistent atrial fibrillation (AF).MethodsWe retrospectively analyzed the clinical data of 78 elderly patients with cardiac valve disease combined with persistent AF in our hospital from 2017 to 2018. The patients were allocated to two groups including a trial group (n=37) and a control group (n=41). There were 21 males and 16 females aged 61 to 74 (65.2±2.5) years in the trial group. There were 23 males and 18 females aged 62 to 76 (64.8±3.3) years in the control group. The clinical effects of the two groups were compared.ResultsThere was no statistical difference in baseline data between the two groups (P>0.05). The aortic occlusion time, extracorporeal circulation time, and operation time of the trial group were longer than those of the control group with statistical differences (P<0.05). There was no statistical difference in postoperative ventilator assistance time, complication rate, mortality, ICU retention time, perioperative drainage, red blood cell transfusion volume, or length of hospital stay between the two groups (P>0.05). At the time of discharge, postoperaive 1-month, 3-month, 6-month, and 12-month, the maintenance rates of sinus rhythm in the control group were statistically different from those of the trial group (P<0.05). Compared with the control group, left atrial diameter, left ventricular end diastolic diameter and the decrease of pulmonary artery systolic blood pressure were statistically different (P<0.05).ConclusionMaze Ⅳ is safe and effective in the treatment of elderly patients with valvular heart disease and persistent AF, which is conducive to the recovery and maintenance of sinus rhythm, and is beneficial to the remodeling of the left atrium and left ventricle and the reduction of pulmonary systolic blood pressure with improvement of life quality of the patients.
