ABSTRACT

Objective:To explore the feasibility and application value of case-based learning (CBL) combined with clinical pathway in thoracic surgery practice teaching.Methods:A total of 30 clinical undergraduate students who practiced from January 2018 to August 2018 were selected and randomly divided into the traditional group and the research group. The traditional group used traditional teaching mode, while the research group adopted the CBL combined with clinical pathway teaching. The scores of theoretical examination and practice skills assessment and the case analysis ability of the two groups were compared at the time of department. In addition, the evaluation of the teaching effect of the two groups of teachers and students was observed through anonymous questionnaires. SPSS 21.0 was used for t-test and Chi-square test. Results:The scores of the students in the research group were better than those in the traditional group, including score of theoretical examination [(88.20±4.02) vs. (80.76±4.62), P<0.001], score of practice skills assessment [(90.80±2.16) vs. (84.80±3.07), P<0.001] and case analysis ability [(89.80±3.34) vs. (81.86±4.31), P<0.001]. The differences were statistically significant. At the same time, the questionnaire showed that the research group was superior to the traditional group in improving students' learning interest, clinical skills, case analysis ability, clinical communication ability, theoretical knowledge understanding and clinical thinking ability, with a statistically significant difference ( P<0.05). While the two groups had no statistically significant difference in students' satisfaction with teachers ( P=0.083). Conclusion:The CBL method combined with clinical pathway teaching method can improve the teaching effect of thoracic surgery practice, which is worth popularizing.

ABSTRACT

@#Objective    To investigate the effects of robotic versus thoracoscopic lobectomy on body trauma and lymphocyte subsets in patients with non-small cell lung cancer (NSCLC). Methods    The clinical data of 120 patients with NSCLC who underwent lobectomy in the same operation group at the same period were collected and divided into a robot group (n=60) and a thoracoscope group (n=60) according to different surgical methods. The operation time, intraoperative blood loss, postoperative drainage time, drainage volume, postoperative hospital stay, complication rate, pain visual analogue scale (VAS) and other perioperative indicators were recorded in the two groups. Inflammatory markers: C-reactive protein (CRP), interleukin-6 (IL-6) and lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) levels were measured before and 1 d, 3 d after surgery. The effects of the two surgical methods on the body trauma and lymphocyte subsets were compared. Results    The operation time, intraoperative blood loss, postoperative drainage time, drainage volume and VAS of the robot group were lower than those of the thoracoscope group, and the differences were statistically significant (P<0.05). On the 1st day after surgery, IL-6 of the thoracoscope group was higher than that of the robot group, while CD3+, CD4+ and CD8+ were lower than those of the robot group, with statistically significant differences (P<0.05). Conclusion    Compared with thoracoscopic lobectomy, robotic lobectomy has less trauma, less inflammatory response, faster recovery, less inhibitory effect on lymphocyte subsets, and has clinical advantages.

ABSTRACT

@#Objective    To explore the clinical value of three-dimensional computed tomography bronchography and angiography (3D-CTBA) in robotic lung segmentectomy. Methods    A non-randomized control study was performed and continuously enrolled 122 patients who underwent robotic lung segmentectomy in our hospital from January 2019 to January 2020. 3D-CTBA was performed before operations in 53 patients [a 3D-CTBA group, including 18 males, 35 females, with a median age of 52 (26-69) years] and not performed in the other 69 patients [a traditional group, including 23 males, 46 females, with a median age of 48 (30-76) years]. The clinical data of the patients were compared between the two groups. Results    All the patients were successfully completed the surgery and recovered from hospital, with no perioperative death. The baseline characteristics of the patients were not significantly different between the two groups (P>0.05). No significant difference was found in the operative time [120 (70-185) min vs. 120 (45-225) min, P=0.801], blood loss [50 (20-300) mL vs. 30 (20-400) mL, P=0.778], complications rate (17.0% vs. 11.6%, P=0.162), postoperative hospital stay [7 (4-19) d vs. 7 (3-20) d, P=0.388] between the two groups. In the 3D-CTBA group, 5 (9.4%) patients did not find nodules after segmentectomy, and only 1 (1.9%) of them needed lobectomy, but in the traditional group, 8 (11.6%) patients did not find nodules and had to carry out lobectomy, the difference was statistically significant (P<0.05). The follow-up time was 10 (1-26) months, and during this period, there was no recurrence, metastasis or death in the two groups. Conclusion    3D-CTBA is helpful for accurate localization of nodules and reasonable surgical planning before operations, and reducing wrong resections in segmentectomy, without increasing the operation time, blood loss and complications. It is safe and effective in anatomical lung segmentectomy.
