Furthermore, 90% agreed that they improved in laparoscopic bowel length measurement after the training experiment. Of all participants, 60% would like to learn more often with a similar training method, while 30% answered neutrally on that question. Figure 3: Percentage Absolute Deviation of the Baseline and Final Bowel Measurements Expressed as median and interquartile range. a) Measurement results before and after the training program were compared for all residents (Z = -1.38, P = 0.17). b) Measurement results of the participants with sufficient practice (N=8) before and after the training experiment were compared (Z = -2.5, P = 0.012). Sufficient practice was defined as practicing at least one time each week. 7 139 Measuring small bowel length in metabolic bariatric surgery: a training experiment
