Structured training curricula for robotic colorectal surgery in China: does laparoscopic experience affect training effects?

BACKGROUND

Robotic surgery has been widely adopted for colorectal cancer (CRC). Many surgeons in China have completed structured training programs and have performed robotic colorectal surgeries. This multicenter study aimed to evaluate the training effects of structured training curricula in China for surgeons with different laparoscopic experiences during their initial implementation of robotic colorectal surgery.

METHODS

Ten surgeons from five high-volume centers participated in this retrospective study. The baseline characteristics, perioperative data, and pathological outcomes were compared between the first 15 robotic surgeries performed by five surgeons with extensive laparoscopic experience (group A) and the first 15 robotic surgeries performed by five surgeons with limited laparoscopic experience (group B) at each center.

RESULTS

Compared with group B, group A showed shorter operation time (200.9 254.2 min, P<0.001), less blood loss (100.0 150.0 mL, P=0.025), and a lower incidence of intraoperative complications (2.7% 21.4%, P=0.015). The reoperation rate (1.3% 5.3%, P=0.036) and postoperative complication rate (6.7% 22.7%, P=0.025) were significantly lower in group A than in group B. There were no statistically significant differences in baseline characteristics (e.g., age, sex, and tumor location) and pathological information (e.g., tumor stage, lymph node count, and tumor size) between the two groups. Radical resection (R0) was performed in all cases.

CONCLUSIONS

In China, structured training curricula can help surgeons with extensive laparoscopic experience make a smooth transition from laparoscopic to robotic surgery. However, the higher intraoperative and postoperative complication rates indicate that structured training curricula still require further refinement for surgeons with limited laparoscopic experience.
