Résumé
To investigate the effect of surgical experience on the perioperative outcomes of endoscopic GreenLight™ (Boston Scientific Corporation, Marlborough, MA, USA) laser enucleation of the prostate (GreenLEP). A multicentre retrospective study of the first patients treated with GreenLEP by six surgeons was conducted. For each patient, surgical experience was coded as the total number of procedures performed by the surgeons before the patient's operation. The learning curve was analysed in terms of changes over time for the following variables: enucleation time, morcellation time, occurrence of intraoperative complications (IOCs), 3-month postoperative International Prostate Symptom Score (IPSS) reduction, and the rate of Pentafecta achievement. In total, 922 patients were analysed. At multivariable regression analyses adjusted for case mix, surgical experience was associated with shorter enucleation and morcellation time (P < 0.001), lower IOC rate (P < 0.001), higher 3-month postoperative reduction in IPSS (P = 0.004), and higher probability of Pentafecta achievement (P < 0.001). The relationship between surgical experience and enucleation time/IOCs appeared as non-linear, with a steep slope reduction within the first 100 cases and a plateau observed after 200 cases, whilst the IPSS improved rapidly early in the learning curve process and plateaued after ~100 procedures. Finally, there was a linear improvement in Pentafecta achievement, with a plateau observed after 270 cases. Surgical experience has a significant impact on the perioperative outcomes for GreenLEP procedures. After adjusting for patient and prostate characteristics, plateau results were achieved after a long learning curve. A more intensely mentored and structured training schedule might allow quicker and safer adoption of the procedure.
