The aim of this study was to analyse the learning curve of the MIA during endoscopic enucleation of the prostate.? METHODS We conducted a prospective study of the first 90 patients treated by endoscopic enu- cleation of the prostate by a single surgeon without previous experience of MIA. The population was divided into 3 consecutive groups of 30 patients. MIA was performed with the morcella- tor Pinranha (Wolf®) and disposable blades (Vmax©). The criteria selected to assess the progress of MIA over time were: duration of MIA (min), the intraoperative complications encountered during MIA and weight morcelleted tissue. The efficacy of MIA was assessed with the ratio weight specimen/MIA duration (min/g) over time. RESULTS The three groups were comparable in terms of age, ASA score of prostate volume. A significant decrease in the duration of MIA was found between groups 1 and 2 (12 versus 5.5 min, P < 0.0001), to reach a plateau in the group 3 (3 min). A significant increase in the efficiency of MIA was found between group 1 and 2 (5.5 versus 11 g/min, P < 0.0001), to reach a plateau in the group 3 (20 g/min) (Figure 1). Bladder injuries were limited (7.7%), superficial and encountered in the early learning phase. CONCLUSIONS In our experience, the MIA required a learning curve estimated between 30 and 60 procedures. © 2017FiguresReferencesRelatedDetails Volume 197Issue 4SApril 2017Page: e331 Advertisement Copyright & Permissions© 2017MetricsAuthor Information Benjamin PRADERE More articles by this author Benoit PEYRONNET More articles by this author Benoit Bordier More articles by this author Julien Guillotreau More articles by this author Kevin Zorn More articles by this author Vincent Misraï More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
