Abstract | BACKGROUND: Long-term durability after Roux-en-Y gastric bypass is challenging in the super-obese population. Although lengthening of biliopancreatic limb (BPL) is associated with higher rates of weight loss, shortening of common limb (CL) is related to higher risk of malabsorption. OBJECTIVES: In this study, we aimed at evaluating the importance of the total alimentary limb length by creating a 2-m BPL diversion with varying CL lengths. SETTING: High-volume bariatric center, Norway. METHODS: Three groups of patients (N = 187) with different limb lengths were included in this retrospective cohort-analysis as follows: group 1 (n = 69; Roux limb = 150 cm, BPL = 60 cm), group 2 (n = 88; BPL = 200 cm, CL = 150 cm), and group 3 ( n = 30; BPL = 200 cm, CL = 200 cm). Weight loss, regain, and failure were analyzed along with malabsorption issues. RESULTS: Preoperative body mass index (BMI) was higher in group 2 (58.5, P < .001) and 3 (57.4) versus group 1 (54.6, P = .011). No other clinically significant differences between the groups were noted. Follow-up rate was 95% at year 2, 74% at year 5, and 52% at year 10. At 10-year follow-up, excess weight loss and total weight loss was higher in group 2 (70.4%; 40.3%) and 3 (64.0%; 35.9%) compared with group 1 (55.9%; 29.2%). Excess weight loss failure was higher in group 1 versus 2 (30% versus 8.3%, P < .001). No difference in short- or long-term complications was seen except higher occurrence of internal hernia in distal Roux-en-Y gastric bypass groups (11.4%, 6.7%). Vitamin and mineral deficiencies occurred more frequently the shorter the CL was. CONCLUSION: Sustainable weight loss in a long-term follow-up is achieved by shortening the total alimentary limb length with a 2-m BPL diversion that should not be attached <200 cm from the ileocecal junction owing to higher rates of internal hernia and vitamin and mineral deficiencies.
