ABSTRACT
@#Objective To compare the clinical effects of segmentectomy and lobectomy for ≤2 cm lung adenocarcinoma with micropapillary and solid subtype negative by intraoperative frozen sections. Methods The patients with adenocarcinoma who received segmentectomy or lobectomy in multicenter from June 2020 to March 2021 were included. They were divided into two groups according to a random number table, including a segmentectomy group (n=119, 44 males and 75 females with an average age of 56.6±8.9 years) and a lobectomy group (n=115, 43 males and 72 females with an average of 56.2±9.5 years). The clinical data of the patients were analyzed. Results There was no significant difference in the baseline data between the two groups (P>0.05). No perioperative death was found. There was no statistical difference in the operation time (111.2±30.0 min vs. 107.3±34.3 min), blood loss (54.2±83.5 mL vs. 40.0±16.4 mL), drainage duration (2.8±0.6 d vs. 2.6±0.6 d), hospital stay time (3.9±2.3 d vs. 3.7±1.1 d) or pathology staging (P>0.05) between the two groups. The postoperative pulmonary function analysis revealed that the mean decreased values of forced vital capacity and forced expiratory volume in one second percent predicted in the segmentectomy group were significantly better than those in the lobectomy group (0.2±0.3 L vs. 0.4±0.3 L, P=0.005; 0.3%±8.1% vs. 2.9%±7.4%, P=0.041). Conclusion Segmentectomy is effective in protecting lungs function, which is expected to improve life quality of patients.
ABSTRACT
Objective To study the short-term(≤1 year) effect of video-thoracoscope in the treatment of chronic obstructive pulmonary diseases (COPD) accompanied with pneumothorax.Methods 52 COPD cases with pneumothorax from June 2005 to June 2007 were divided into thoracoscope group(n=28) and open heart group(n=24).The patients were followed up at 1,6 and 12 month after surgery,for determination of BODE index,including body mass index,air block,difficulty in respiratory and motor ability.Results No operative death and servere complicatins occurred.Pneumothorax did not relapse.One month after surgery,air block was[(58.62±15.73)% vs (50.12±11.38)%],difficulty in respiratory was[(1.04±0.37)s vs( 1.72±0.45)s] and motor ability was [(387.32±52.07)m vs (318.35±61.52)m] in thoracoscope group and open heart group (P<0.05).At the six month after surgery,body mass index was[(27.19±2.18)kg/m2 vs (20.90±2.35)kg/m2] in thoracoscope group and open heart group(P<0.05);At the 12 month after operation,there was no significant difierence in BODE index between the two groups(P>0.05).Conclusions Video-thoracoscope in treating COPD with pneumothorax can remarkably improve the quality of life early after surgery.
