Low-fidelity bench models for basic surgical skills training during undergraduate medical education

Authorship SCIMAGO INSTITUTIONS RANKINGS

It is remarkable the reduction in the number of medical students choosing general surgery as a career. In this context, new possibilities in the field of surgical education should be developed to combat this lack of interest. In this study, a program of surgical training based on learning with models of low-fidelity bench is designed as a complementary alternative to the various methodologies in the teaching of basic surgical skills during medical education, and to develop personal interests in career choice.

Procedure	Skilss
Drawing the ellipse	A)The ellipse must be formed by two arcs; B)The arcs must be symmetrical in relation to the midline that separates them and must meet the ends forming a convexity; C)The curvature used should be based on a length-width ratio of 3:1 to 4:1 of the ellipse formed; D)One should use a 30° angle at the ends of the ellipse (the intersection of the arcs).
Safety margins	A)A line shall be marked around the periphery of skin lesion to delimit the safety margins; B) According to the current recommendations for surgical resection of most cases of NMSC, extensions of safety margins should be 2-10 mm.
Incision of the ellipse	A)Smooth moves with a scalpel; B)Cutting angle between 30° and 60°; C)Cuts of the subcutaneous tissue with only 1 or 2 movements; D)Avoid damaging of the edges of the ellipse.
Excision of the ellipse	A)Handle tissue gently to avoid damaging the epidermis; B)Cuts in the same plane while removing the tissue; C)Resect the same amount of tissue in all areas of the wound.

	1	2	3	4	5
Respect for tissue	Often used unnecessary force on tissue or caused damage by inappropriate use of instruments		Careful handling of tissue but occasionally caused inadvertent damage		Consistently handled tissues appropriately, with minimal damage
	1	2	3	4	5
Time and motion	Many unnecessary moves		Efficient time and motion, but some unnecessary moves		Economy of movement and maximum efficiency
	1	2	3	4	5
Instrument handling	Repeatedly makes tentive or awkward moves with instruments		Competent use of instruments, although occasionally appeared stiff or awkward		Fluid moves with instruments and no awkwardness
	1	2	3	4	5
Suture technique*	Clumsy and insecure, inadequately tying knots and inability to maintain tension		Careful and slow with most knots placed properly with proper tension		Excellent control of the suture, with proper placement of knots and correct tension

Elliptical excision biopsy technique**	Lack of knowledge about the parameters (<2 mm or >10 mm margins); angles much different from 30º; lenght- width ratio very different from 3-4:1		Adequate margins (2- 10mm); angle at the ellipse ends slightly different from 30º; length-width radio slightly different from 3-4:1		Adequate margins (2- 10mm); 30º angles at the ellipse ends; lenght- width radio 3-4:1

Flow of operation and forward planning	Frequently stopped operating or needed to discuss next move		Demonstrated ability for forward planning with steady progression of operative procedure		Obviously planned course of operation with effortless flow from one move to the next
	1	2	3	4	5
Knowledge of specific procedure	Deficient knowledge. Needed specific instruction at most operative steps		Knew all important aspects of the operation		Demonstrated familiarity with all aspects of the operation
