Objective. To study the set of experience of laser vaporization in the treatment of chronic hemorrhoids by the method of constructing learning curve
Methods. Based on 90 isolated LV performed by one surgeon, the process of gaining experience by constructing learning curves was studied. The criteria of mastery were the duration of the operation, the intensity of the pain syndrome, the frequency of postoperative bleeding.
Results. The duration of the period of mastering the experience, determined by the regression method, based on the time of the intervention, depending on the goal, was 4, 23 and 66 operations. On the basis of postoperative bleeding with the task of reducing their frequency by 2 times, performed by the CUSUM test, the period of LV development was 36 operations.
Discussion. The results of the study made it possible to explain the reasons for the differences in the duration of the experience of laser transmucous vaporization of hemorrhoids, depending on the chosen model for constructing the learning curve, the sign of experience, and the goals set for achieving it. The most objective way to study the experience of LV is CUSUM analysis of the frequency of postoperative bleeding
Conclusion. The use of various mathematical models and signs of experience allows you to build an objective graph of the learning curve and obtain the most reliable research results.

Keywords: laser vaporization of hemorrhoids, learning curve, results of laser vaporization, complications of laser vaporization
