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

Abstract

Introduction: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.Materials and Methods: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.Results: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.Conclusions: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.

The avian model: a novel and cost-effective animal tissue model for training in neonatal laparoscopic surgery

“…Data were collected using a Likert scale (1 = strongly disagree/bad; 2 = somewhat disagree/somewhat bad; 3 = neutral/neutral; 4 = somewhat agree/somewhat good; 5 = strongly agree/good) on a structured standardized questionnaire based on the Michigan Standard Simulation Experience Scale (MiSSES) [6] using chicken. Ramachandran et al described a model for laparoscopic pyeloplasty using chicken crop, Laguna et al have presented a chicken model for urethrovesical anastomosis and Singh et al for laparoscopic ureteric reimplantation [21][22][23].…”

Development of a photographic handbook to improve cystoscopy findings during resident’s training: A randomised prospective study

“…At the same time, the importance given to the learning curve needed in different diagnostic and therapeutic procedures to achieve adequate outcomes and results has increased. Many theoretical and practical training models have been introduced with the purpose of reducing the learning curve itself, in order to guarantee significant results in the shortest possible time [4][5][6][7][8]. In particular, in endourology, given the massive use of hands-on technology and instrumentation, we can find models of teaching and training aimed to improve the skills of residents and urologists in the use of these instruments and in the correct execution of procedures [9][10][11][12][13].…”

What's inside?

“…describe a chicken model that could be used for training for laparoscopic surgery. [ 5 ] Robust validation studies are limited, but the available evidence would suggest that a trial of these models could prove useful.…”
