| Popis: | Supplemental Digital Content is available in the text Large loop excision of the transformation zone (LLETZ) is one of the most common procedures in operative gynecology and it is a routine part of the surgical training program of residents. There is, however, no established and standardized method of teaching residents how to perform LLETZ. Here, we present a surgical training model and assessed the improvement of surgical skills during repeated hands-on trainings of LLETZ in this model. Surgical novices and experts were recruited and were shown a LLETZ training video and then performed 3 LLETZ training sessions on consecutive days. Surgical skills were assessed by Objective Structured Assessment of Technical Skills (OSATS). Global rating scale (GRS), confidence (CON), fragmentation rate (FR), performance time (PT), and OSATS scores were calculated. Intra- and interobserver variabilities were determined. The construct validity of OSATS was assessed comparing metric scores of novices with those of experts. Sixty-eight probands (58 novices, 10 experts) were recruited.
