BS SO11 - Impact of various biliopancreatic limb lengths on EBWL, Nutritional deficiencies and resolution of ORMs -MGB/OAGB

Abstract Background OAGB was first described by Robert Rutledge. There have been a few modifications of MGS since its first introduction. There have been modifications in the limb length, pouch side, type, and location of anastomosis. Concerns have been raised about nutritional deficiencies by various authors about the longer limb length. Few other authors have published promising results from their studies regarding good outcomes on longer limb length. Method We follow BMI based guidelines at our center to decide on OAGB limb length.BMI < 50- BP limb length – 150 cmBMI >50 BP limb length- 200 cmBMI > 60 BP limb length- 250 cm. We analysed our results from BP limb lengths >/=200 cm in terms of EBWL, ORM resolutions, Nutritional deficiencies and compared it to similar outcomes in BP limb lengths of 150 cm Results Our data is currently under review. Initial assessment suggests promising results of longer limb lengths with no major complications highlighted. All the longer limb length patients are under 3 monthly follow up with 2 years follow up data now being analysed. Literature review suggests inadequate weight loss with shorter limb lengths. The longer limb lengths are associated with nutritional deficiencies. We are excited to take this opportunity to discuss our results Conclusion Limb length should be tailored as per patient factors and available support. One standard limb length doesn't apply to all the patients.
