Objective To systematically review the effects of problem-based learning (PBL) versus lecture-based learning (LBL) teaching models on students in surgery education in China. Methods Such databases as CNKI, WanFang Data and PubMed were electronically searched for literature on PBL versus LBL applied in surgery education in China up to June 30th, 2013. According to the inclusion and exclusion criteria, we screened literature, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2 software. Results Sixteen studies were included totally, all of which were low in quality. Compared with LBL, PBL was superior in surgery comprehensive scores (WMD=4.98, 95%CI 3.88 to 6.09, Plt;0.000 01), fundamental theoretical knowledge (WMD=3.09, 95%CI 0.81 to 5.38, P=0.008), clinical manipulation skills (WMD=4.70, 95%CI 2.69 to 6.71, Plt;0.000 01), and practical ability (WMD=2.13, 95%CI 1.11 to 3.15, Plt;0.000 1) with significant differences. Conclusion PBL teaching method is superior to LBL in surgery education.
Objective To explore the safety and feasibility of preferential manual bronchoplasty in single-port video-assisted thoracoscopic surgery (VATS) upper lobectomy. MethodsThe clinical data of 457 patients with non-small cell lung cancer who underwent single-port VATS lobectomy in the Department of Thoracic Surgery of Peking University First Hospital from March 2020 to March 2022 were retrospectively analyzed. The patients were divided into a preferential manual bronchoplasty group and a traditional single-port VATS lobectomy group with a 1 : 1 propensity score matching for further research. Results A total of 204 patients were matched, and there were 102 patients in each group. There were 50 males and 52 females aged 62.2±10.1 years in the preferential bronchoplasty group, and 49 males and 53 females aged 61.2±10.7 years in the traditional single-port VATS group. The preferential bronchoplasty group had shorter surgical time (154.4±37.0 min vs. 221.2±68.9 min, P<0.01), less bleeding (66.5±116.9 mL vs. 288.6±754.5 mL, P=0.02), more lymph node dissection (19.8±7.5 vs. 15.2±4.7, P<0.01), and a lower conversion rate to multi-port or open surgery (2.3% vs. 13.8%, P=0.04) in left upper lobe resection. In the right upper lobe resection surgery, there was no statistical difference in postoperative results between two groups. There was no perioperative death or occurrence of bronchopleural fistula in both groups. ConclusionCompared with traditional single-port VATS upper lobectomy, preferential bronchoplasty has similar safety and feasibility. In addition, priority bronchoplasty in left upper lobectomy has the advantages of shorter surgical time, less bleeding, more lymph node dissection, and lower conversion rate to multi-port or open surgery.
