Abstract

Abstract:

Objective

To study the application effect of problem-based learning （PBL） combined with surgical video teaching in the standardized training of general surgery specialists.

Methods

A retrospective analysis was performed on 42 trainees who received standardized training of specialist physicians from January 2017 to December 2022， and they were divided into control group （traditional PBL group， n=22 cases） and experimental group （PBL+ surgical video clip teaching group， n=20 cases）.SPSS 16.1 statistical software was used to analyze the data.Theoretical test scores and surgical operation test scores were expressed as （x± s），independent sample t test was used， and clinical work time was used as χ² test.P＜0.05 indicated that the difference was statistically significant.

Results

The theoretical scores in the first year of experimental group were lower than those in the control group （P=0.57）， and the test scores in the second year were higher than those in the control group （P＜0.05）.In the first two years， the test scores of the experimental group were higher than those of the control group （P＜0.05）.Surgical design （t=3.877， P＜0.001）， significant anatomical exposure（t=3.452， P=0.002） and surgical duration （t=2.956， P=0.032） of the experimental group were better than those of the control group.

Conclusion

PBL combined with surgical video clip teaching has achieved good results in the standardized training of general surgery specialists， and can be used as a new form of clinical teaching.
