To explore the effectiveness of laparoscopic surgery simulator for education and training in transabdominal preperitoneal (TAPP) hernia repair.

A total of 41 trainees who received TAPP surgical training at the Department of Hernia and Abdominal Wall Surgery, Beijing Chaoyang Hospital, Capital Medical University, between January 2018 and December 2023 were included. According to the training methods, trainees were divided into an observation group (n=29) and a control group (n=12). The observation group received a three-week laparoscopic surgery simulator training program, while the control group received traditional instruction through course materials, video lectures, and intraoperative teaching. The TAPP peritoneal suturing skills of trainees in both groups were evaluated before and after the training, and feedback on the training course was collected.

The assessment of TAPP peritoneal suturing skills showed that after training, the simulator group achieved significantly higher scores than the traditional teaching group (P<0.05). After training, confidence in performing the procedure in clinical practice increased in both groups, with a statistically significant difference between the two groups (P<0.05).

Laparoscopic surgery simulators can significantly improve trainees' laparoscopic surgery skills and enhance their confidence in performing laparoscopic surgery.
