Figure 2: Cut-off Values The acceptable cut-off value of 10% and the unacceptable cut-off point of 15% for the different measured limb lengths. RESULTS One measured value was excluded due to an incorrect measurement. Three of the metabolic bariatric surgeons have performed more than 2000 laparoscopic metabolic bariatric surgical procedures during their career and one of the metabolic bariatric surgeons performed more than 500 metabolic bariatric surgical procedures (Table 5, Appendix I). As shown in Table 1, the mean measured lengths of the 150 cm task by the four metabolic bariatric surgeons individually were 131 ± 25, 158 ± 17, 156 ± 19, and 158 ± 10 cm, respectively. As a group, the surgeons estimated 22 out of 39 times (56%) between the lower and upper margins of 10% deviation and 7 times (18%) outside the 15% margin. Mean measured values on the 180 cm distance were 145 ± 24, 205 ± 29, 168 ± 23, and 172 ± 21 cm, respectively. The estimated lengths on the 180 cm task were 18 out of 40 times between the lower and upper margins (45%), and 16 times (40%) outside the 15% margin. On the 210 cm task, the surgeons measured 176 ± 31, 223 ± 32, 210 ± 24, and 221 ± 24 cm. The measurements were 18 out of 40 times between the 10% margins (45%) and 13 times (33%) outside the 15% margin. -15% -10% Goal +10% +15% 127,5 135 150 165 172,5 153 172 180 198 207 178,5 189 210 231 241,5 118 6
