“…A training approach that would have set a fixed number of procedures or number of training hours would have ignored the individual variability with respect to skill acquisition. Skill acquisition, and thus the amount of training required to reach a performance goal, shows significant inter-individual variability [10,13]. Our observation that VR-trained subjects improved significantly and performed capsulorhexis more consistently demonstrates the efficacy of this training approach.…”

“…Visuo-spatial ability, the ability to manipulate simple and complex mental representations, correlates reasonably well with performance on laparoscopic tasks (Hedman et al, 2006;Keehner et al, 2006;McClusky et al, 2005;Ritter et al, 2006;Wanzel et al, 2002). Correlations reported in the previously mentioned studies vary from .00 to .76 with a mean of .24, indicating a moderate effect, depending on the type of visuo-spatial ability test used and performance measure for laparoscopic ability.…”

“…Correlations reported in the previously mentioned studies vary from .00 to .76 with a mean of .24, indicating a moderate effect, depending on the type of visuo-spatial ability test used and performance measure for laparoscopic ability. The highest correlations have been found between perceptual ability (as measured by the PicSOr test, see McClusky et al, 2005, andRitter et al, 2006) and performance: .76 and .92. Based on Carroll's (1993) classification, spatial memory is often studied as a component of the visualization factor (Hedman et al, 2007).…”

Learning minimally invasive surgery (MIS) differs substantially from learning open surgery and trainees differ in their ability to learn MIS. Previous studies mainly focused on the role of visuo-spatial ability on the learning curve for MIS. In the current study, the relationship between spatial memory, perceptual speed, and general reasoning ability, in addition to visuo-spatial ability, and performance on a MIS simulator is examined. Fiftythree laparoscopic novices were tested for cognitive aptitude. Laparoscopic performance was assessed with the LapSim simulator (Surgical Science Ltd., Gothenburg, Sweden).Participants trained multiple sessions on the simulator until proficiency was reached.Participants showed significant improvement on the time to complete the task and efficiency of movement. Performance was related to different cognitive abilities, depending on the performance measure and type of cognitive ability. No relationship between cognitive aptitude and duration of training or steepness of the learning curve was found. Cognitive aptitude mediates certain aspects of performance during a training on a laparoscopic simulator. Based on the current study, we conclude that cognitive aptitude tests cannot be used for resident selection but are potentially useful for developing individualized training programs. More research will be performed to examine how cognitive aptitude testing can be used to design training programs.

“…In this regard, patient-focused simulation can yield benefits both for the patient and for the colposcopist during the early learning phase [17]. We believe that selection of trainees for accreditation may assume significance in the future; one criterion for selection could be visuo-spatial aptitude as this can reliably predict psychomotor performance [18,19]. Better selection of candidates may improve the outcome for patients while the trainee is under direct supervision in the early stages of learning and minimize treatment failure rates among this patient population.…”

Purpose This study was designed to assess fragmentation of Large loop excision of the transformation zone (LLETZ) specimens, its influence on short-term cytological outcome, and the risk factors for specimen fragmentation, as we well as trainee performance on clinical outcome. Method This retrospective study was performed at a cancer center. Women who underwent LLETZ for suspected high-grade cervical intra-epithelial neoplasia (CIN) over a 5-year period were included. Patients were identified through a regional database. Data were obtained from hospital and regional databases. Fisher's exact test was used.Results 75 % of all specimens were obtained intact. When the LLETZ specimen was intact, 89 % of smear tests were reported as negative, against 86 % when the specimen was fragmented. Fragmentation was significantly associated with high-grade smear results at 6 months. Trainee status was significantly related to specimen fragmentation. Conclusion Fragmentation of LLETZ specimens is associated with an increased likelihood of obtaining a highgrade smear at 6 months post treatment. Enhancing the colposcopy training may help improve clinical outcome.
