Face, content, and construct validity of a novel chicken model for laparoscopic ureteric reimplantation

Simulation-based training in laparoscopic urology is essential, as these surgeries require a different skill set. We validated a chicken model for laparoscopic left modified Lich Gregoir type of ureteric reimplantation.

Prospective observational study was conducted from August 2016 till February 2017. Thirty novice surgeons and 20 trained laparoscopic surgeons were included in the study. The relevant chicken anatomy and surgical steps were described to all the surgeons. The surgeons were asked to fill an eight-point questionnaire after finishing the procedure and score it on a scale of 1-5. The trainee's performance was also recorded by an investigator on a proforma. The investigator recorded dissection time, suturing time, quality of dissection, quality of suturing, and integrity of anastomosis on a scale of 1-5.

All the participants in the study gave a mean score of 3 or more to all the questions asked, except for one question pertaining to tissue feel. Both the groups rated the usefulness of the model very highly with a mean score of 4.20 and 4.15, respectively. Difference in the time taken for dissection and suturing along with the quality of suturing was statistically significant in favor of the expert group.

The chicken model for laparoscopic left modified Lich Gregoir type of ureteric reimplantation is a useful, effective, cognitive training tool. This model has a face, content, and construct validity to be used as a teaching and learning tool in laparoscopic urology.
