Objective

2

To compare the training effect between the laparoscopic simulated uterine model (LSUM) with multi-angle suture and the traditional surgical model and to identify a laparoscopic model more suitable for gynecological resident training.

Methods

2

Forty-eight residents who were trained in Sir Run Run Shaw Hospital affiliated to Zhejiang University School of Medicine from February 2021 to February 2023 were selected. They were trained in batches

with each batch randomly divided into two groups of the same size. The observation group was trained with the traditional surgical model and general surgical videos

while the experimental group was trained with a self-developed LSUM with multi-angle suture and corresponding surgical videos. Finally

the two groups were compared for the assessment results

and a questionnaire survey was conducted in the experimental group. The statistical software SPSS 20.0 was used for

t

-test or chi-square test of the results.

Results

2

There were no significant differences between the two groups in age

gender distribution

education level

and clinical experience. In theoretical assessment results

no significant difference was shown between the experimental group and the observation group [(82.63±3.93) vs. (85.00±6.15)

P

>

0.05]. In skill assessment results

there was no significant difference between the two groups in the anterior wall assessment [(83.08±4.47) vs. (82.79±3.58)

P

=0.804]. However

in the assessment of the lateral and posterior walls

the proficiency

accuracy

and degree of coordination between two hands of the experimental group were better than those of the observation group

with the total score being significantly different [(64.13±3.34) vs. (46.75±3.50)

(62.25±4.41) vs. (45.00±2.89)

P

<

0.001]. In the questionnaire survey

the experimental group had a high degree of satisfaction with the LSUM and thought that the highly simulated model was beneficial to their training.

Conclusions

2

Compared with the traditional surgical model

the LSUM with multi-angle suture can effectively improve the operation level of residents

which provides a new idea for the laparoscopic simulation training of gynecological residents in the future.
