Abstrakt: Purpose: To evaluate a simulation-based standardized training program for type 1 loop electrosurgical excision procedure (LEEP) under direct colposcopic vision in postgraduate teaching.
Methods: Seventeen participants (five experienced and 12 novice surgeons) performed 170 simulated cervical excisional procedures. Each participant performed 10 type 1 (cone length between 8 and 10 mm) excisional procedures under direct colposcopic vision on a low-fidelity simulator. Length of specimen was measured after each excision allowing the surgeons a subsequent resection to ensure a cone length of more than 8 mm. Main outcome measures were cone length, specimen fragmentation, and a self-developed score (LEEP score), which allowed the simultaneous evaluation of both measured parameters.
Results: The precision of the excision showed statistically significant improvement in the novice group during the training procedures after five procedures [LEEP score 1.61 (SD 1.34) vs. 0.46 (SD 0.58); p = 0.023], while experts showed consistently high performance. Inexperienced surgeons performed more frequently cuts that were too deep than experienced surgeons (33/120, 27.5% vs. 4/50, 8%; p = 0.003).
Conclusions: Low-fidelity simulation training seems to be an effective method for learning the accurate cone length for a type 1 excision for novice surgeons. As excessive excisions are related with high risk for premature delivery in subsequent pregnancies, in our opinion, LEEP should be practiced in simulation training, especially before performing in woman of reproductive age.
