BACKGROUND: The study was carried out to determine the learning Curve patterns for basic laparoscopic technical skills. METHODS: Thirty-seven surgical residents with limited laparoscopic experience performed 10 repetitions of 6 tasks on a virtual-reality trainer (MIST-VR) with standardized distribution of practice. Assessment was based oil tune. errors, and economy of motion as measured by MIST-VR. Proficiency levels were established by testing experienced laparoscopic Surgeons. RESULTS: Four learning curve patterns were determined. Surgeons in group I (5.4%) demonstrated proficiency from the beginning group 2 (70.3%) achieved predefined expert criteria between 2 and 9 repetitions; group 3 (16.2%) demonstrated improvement bill was unable to achieve proficiency within 10 repetitions. Group 4 (8.1%) underperformed and showed no tendency of skills improvement. reflecting a group of subjects who probably are unable to learn laparoscopic technique. CONCLUSIONS: The results indicated that a group Of Subjects Could not reach proficiency in the psychomotor skills relevant for laparoscopy. We believe that this is an important issue that should be addressed in future research. (C) 2009 Elsevier Inc. All rights reserved.
