Objectives:
Outpatient hysteroscopy has become an integral part of postgraduate training in gynecology. It is an operator-dependent procedure, however there are no recommendations regarding total number of performed procedures to reach proficiency.
Material And Methods:
This study aimed to assess the learning curve (LC) using cumulative summation test for learning curve (LC-CUSUM).
Results:
A success rate of 97% a failure rate ≥ 10% were established to denote an adequate and an inadequate performance. A third-year trainee needed 56 procedures to reach the predefined level of performance.
Conclusions:
As the length of the LC for outpatient hysteroscopy seems highly variable, it is reasonable to provide tailored monitoring while training.
