Anaemia After One Anastomosis Gastric Bypass

Letter to Editor/LED Reply

Dear Editor,

Many thanks for your kind invitation to comment on this letter in response to the article [1] published recently in Obesity Surgery. First of all, it is important to understand what Bailly et al. [1] found in their study. They found that amongst those who were hospitalised in France, for one reason or other, and had undergone a primary bariatric procedure between 2008 and 16, anaemia due to micronutrient deficiency was more likely to be listed as the main or related diagnoses in those who underwent a gastric bypass (GB) compared to those who underwent a sleeve gastrectomy (SG). Authors of this letter point out that others [2] have found anaemia rates to be higher with SG than GB, Roux-en-Y gastric bypass (RYGB) in particular. They further contend that the results might be due to the possibility that GB cohort in the study by Bailly et al. [1] includes a large number of patients who underwent one anastomosis gastric bypass (OAGB)—an increasingly popular procedure in...
