1172 Innovative Low-Cost Vascular Anastomosis Simulation Training Model for Vascular Anastomosis Training

Abstract

Abstract Aim Vascular anastomosis is an important but complex skill requiring mastery by trainees across multiple specialities, with significant risk of suboptimal outcomes. Simulation allows multiple repetitions of a procedure within controlled environment, allowing training without accompanying patient risk. Current simulation courses on vascular anastomosis are expensive and inaccessible to several junior trainees. A low-cost scaffold was developed for vascular anastomosis training and aimed to assess trainee feedback on utility and acceptability. Method The kit was built using following: Six 27 x 0.9 cm latex balloons, Ferrero Rocher chocolate box, Polypropylene 6.0 surgical sutures, Castroviejo needle holder and Forceps. Sharp scissors were used to make openings in the chocolate box, the balloons were then passed through. The kit’s utility was assessed via trainee feedback (N=16, ranked 1-5 where 1 was Unsatisfactory and 5 was Excellent). Results Trainees were able to perform various types of anastomoses: end-to-end, end-to-side, and patching, using our model. The resistance to needle passage through latex balloons was found to closely resemble that of real arteries and veins. Median rating of different categories in trainee feedback were as followed: Improved understanding 4, Helped practice 5, Realistic 4, Appropriateness for learning 4 and Affordability 5, ranging between 3 and 5. Conclusions Improved skills lead to better outcomes in surgical practice. Steps should be taken to make simulation more accessible. Low-cost models help reduce financial impact on trainees and are suitable for a wide range of institutions, including those with limited resources. Subsequent research should assess the effectiveness of this model across various contexts.
