Curva de aprendizaje de la discectomía microendoscópica para el tratamiento de la hernia discal lumbar

The duration of surgical operating time decreased over the course of the study to stabilise around 62-69 min. There were complications in 14 patients (11.7%), the most frequent of which was incidental durotomy (3 cases, all during the learning curve period). There were six (5%) conversions to open discectomy (4 patients in the first 30 cases). After this stage, conversion to open procedure was exceptional and there were no complications related to technique. The MED is a predictable and safe procedure that can treat all types of herniated discs through an 18 mm incision without detaching the muscles, providing similar results to those obtained with conventional techniques, as it is based on the same surgical principles.
