A simple, inexpensive device for teaching the loop electrosurgical excision procedure

OBJECTIVE: To develop an inexpensive and practical inanimate model to teach the loop electrosurgical excision procedure in a resident clinic. TECHNIQUE: A vaginal speculum is inserted into one end of a cardboard tube. At the opposite end, a piece of knockwurst sausage is inserted into the cardboard tube. A grounding pad is attached to the distal end of the sausage. The teaching session proceeds using a colposcope or direct visualization. After the training session, the excised and uncut portions of sausage can be examined. EXPERIENCE: Faculty found this inanimate model an excellent way to teach residents how to use the loop electrode, and the resident staff appreciated its merits as a useful prelude to treating cervical disease in women. The house staff adapted to the confines of the vagina and transferred skills acquired from working with the cardboard tube, where instruction and constructive criticism can be given without the presence of apprehensive patients. CONCLUSION: A simple, inexpensive, inanimate model has been developed to teach the loop electrosurgical excision procedure. The materials required to construct it are available to any colposcopy clinic.
