title: Laparoscopic sacrocolpopexy for female genital organ prolapse: establishment of a learning curve.
abstract: OBJECTIVE
  The widespread diffusion of laparoscopic sacrocolpopexy in the management of female genital organ prolapse is hampered by its presumed length and technical difficulties. The aim of our study was to analyse the learning curve of a senior urogynecologic surgeon who was initiated into this technique.
  
  
  METHODS
  The first 48 laparoscopic sacrocolpopexies performed by the same surgeon were analysed retrospectively for pre-operative, operative and post-operative data. At the time of the study, patients were asked about their degree of satisfaction by an anonymous questionnaire. To discover a turning point, the duration of each procedure was reported and the study population was divided into 8 equal groups of 6 interventions each, classed chronologically. Statistical analysis was carried out by Mauchly's sphericity test and then by Student-Newman-Keul's test. Other descriptive statistics were computed with the use of standard methods for means, medians and proportions.
  
  
  RESULTS
  The mean operative time was of 236.9 min. The learning curve showed a linear decrease in the duration of surgery with a turning point after 18-24 procedures (p<0.001). It was marked by 2 (4.1%) minor operative complications (2 cystostomies) and 2 immediate post-operative ones: one port-site hernia and one case of urinary retention. At 1 month, 1 patient (2.2%) presented an erosion of the posterior mesh. The mean follow-up was of 15.8 months. During this period, 2 patients (4.1%) presented with a recurrence of prolapse and 6 (12.5%) with de novo stress urinary incontinence. Forty-five patients (93.7%) answered an anonymous questionnaire regarding satisfaction: 40/45 (88.8%) were totally satisfied, 4 (8.8%) moderately and 1 (2.2%) not satisfied.
  
  
  CONCLUSIONS
  The learning curve of laparoscopic sacrocolpopexy shows a steady decrease in the duration of surgery. A turning point is observed after 18-24 procedures. During the learning curve there is no increased morbidity. Anatomical and functional results at short and medium terms are similar to those reported in the literature.
