Evaluation of the learning effect of students after structured training of transanal total mesorectal excision

Objective To explore the effect and significance of structured training through the clinical work carried out by the trainees after undergoing structured training of transanal total mesorectal excision (taTME). Methods Statistical analysis of 20 surgical outcomes, postoperative complications, and subjective proficiency evaluation of taTME surgery performed after training through retrospective analysis. Results Twenty patients were divided into the first 10 cases (group A) and the latter 10 cases (group B) for grouping comparison. There was no statistical difference in the occurrence of surgical bleeding, preventive ostomy and anastomotic leakage, and there was no difference in the total operation time between the two groups, the time of perineal operation (t=2.557, P=0.05) and the time of the anus platform (t=4.575, P<0.01) were significantly lower than that of group A. There were more patients with manual anastomosis in group B than those in group A. There was no statistical difference in the evaluation indexes of prostate or vaginal posterior wall identification and suture of the two groups of patients. There were statistical differences in the evaluation of the quality of the anastomosis (t=8.667, P<0.05). Conclusion Before carrying out a taTME operation, through structured training, this reasonable teaching method can enable clinicians to deeply grasp the anatomical structure of pelvic perianal, shorten the learning curve, improve the safety of operation and protect the rights and interests of patients.
