Abstract

Obesity increases the risk for diseases and early death. In Norway bariatric surgery is offered to persons with morbid obesity (body mass index (BMI) ≥ 35 kg/m 2 with at least one obesity related comorbidity or KMI ≥ 40 kg/m 2 ) when other treatments have been ineffective. We have summarized research of long-term effects after bariatric surgery compared with non-surgical treatment in persons with BMI ≥ 30 kg/m 2 . Based on the results from eight randomized controlled studies with follow-up of up to two years and eight prospective controlled studies with follow-up for up to 20 years, we conclude that: 1. It is unclear whether bariatric surgery reduces total mortality and cardiovascular deaths from myocardial infarction and stroke. The quality of evidence is low to very low. 2. Bariatric surgery may induce a significant and persistent weight loss of 15-20 % for up to 10 years, depending on surgery type. The quality of evidence is moderate. 3. Bariatric surgery may reduce prevalence of type 2 diabetes mellitus and remission of hypertension. The quality of evidence is moderate for diabetes and low for hypertension.4. Bariatric surgery may increase quality of life assessed as physical component scores. The quality of evidence is low.5. It is unclear whether bariatric surgery has effect on symptoms of anxiety and depression. The quality of evidence is very low.6. Prevalence of adverse events were unsystematically and inadequately reported. Bariatric surgery had a positive effect on several outcomes, but effect size may vary based on type of surgery and treatment in the non-surgical groups. The largest and most important weakness is the lack of large studies of good quality with long-term follow-up.

Abstract

Obesity is a world disease that does not stop evolving at the moment, and has an impact on the everyday life of those who suffer from it. A method to fight against this condition is the bariatric surgery. This type of intervention, which modifies the digestive tract of the patient, is going to allow him to !ose weight and to improve some of his comorbidity. Carried out in very specific conditions, it also contains disadvantages. So, besides the risks connected to the surgical operation strictly speaking, the obesity's surgery is going to disrupt the assimilation of medicine and micronutrients.What physiological and medicinal modifications is the bariatric surgery going to engender? What medicine to avoid or which formulations to favor? And what about micronutritional deficiencies? A fan of questions, which will be approached in particular during this report... L'obésité est une maladie mondiale qui ne cesse d'évoluer à l'heure actuelle, et a un impact sur la vie quotidienne de ceux qui en souffrent. Une méthode pour lutter contre cette condition est la chirurgie bariatrique. Ce type d'intervention, qui modifie le tractus digestif du patient, va lui permettre de perdre du poids et d'améliorer certaines de ses comorbidités. Réalisée dans des conditions bien spécifiques, elle comporte aussi des inconvénients. Ainsi, en plus des risques liés à l'intervention chirurgicale à proprement parlé, la chirurgie de l'obésité va perturber l'assimilation des médicaments et des micronutriments. Quelles modifications physiologiques et médicamenteuses la chirurgie bariatrique va-t-elle engendrer ? Quels médicaments éviter ou quelles formulations privilégier ? Et qu'en est-il des carences micro nutritionnelles ? Un éventail de questions qui seront notamment abordées au cours de ce mémoire...

Abstract

Présentation de l'éditeur : "L'obésité morbide est devenue au cours des 10 dernières années un problème de santé publique en France et dans le monde. La chirurgie bariatrique connaît un véritable essor en France et le nombre annuel d'interventions a triplé depuis 2006 pour dépasser 53 000 séjours en 2014. Cependant, si la chirurgie de l'obésité est actuellement largement diffusée dans les établissements de santé en France, seule la moitié des 356 centres français de chirurgie pratiquaient une activité bariatrique en 2011 et une seule intervention représentait alors plus de 80 % de leur activité. Parallèlement, un quart des centres ayant débuté cette activité depuis 2007 était en mesure de proposer trois interventions bariatriques différentes. Ces données posent la question du niveau d'expertise des centres et de la prévention ainsi que de la prise en charge des complications post-opératoires. Ce livre apporte une vision globale de la prévention et de la prise en charge des complications actuelles de la chirurgie de l'obésité. Deux études prospectives et une étude de données nationales incluant plus de 180 000 patients ont été utilisées"

Abstract

Bariatric surgery has been associated with a better control of type 2 diabetes mellitus in several clinical trials. The growing incidence of the disease and the seriousness of its consequences, not only regarding morbidities but also mortality and costs for public heath, make of bariatric surgery a relevant topic of interest. The primary objective of the study is the evaluation of the effectiveness of different bariatric surgery techniques in the armamentarium of type 2 diabetes mellitus. The secondary objective is the analysis of the effects of surgery on the other comorbidities associated with obesity. To answer these questions, we conducted a retrospective study including 96 patients with a glycated hemoglobin level of 6.5% or more without any treatment or a glycated hemoglobin level of 6% or more of medically treated, who have had a gastric bypass (N=75) or a sleeve gastrectomy (N=21) performed in the CUSL and who have been followed at 4+/-1 months, 10+/-1.5 months after the surgery. A glycated hemoglobin level of less than 6.5% without any pharmacological therapy was chose as definition of diabetes remission. The mean age of the patients at baseline was 52+/-10 years and 57%were women. The mean baseline weight was 119+/-24 kg and the mean baseline BMI 42.8+/-6.8 kg/m². The mean baseline glycated hemoglobin level was 7.7+/-1.4% and the mean duration of the disease 7+/-7 years. Out of the 96 patients, 76% completed a 10-months-follow-up and 41% and 18-months-follow-up. At 18 months, at least 54% were in remission, and no difference between the 2 groups was found regarding the rate of remission (55% of remission rate after gastric bypass and 52% after sleeve gastrectomy, p+0.890). Reductions of HbA1c by 1.4+/-1.2% at 4 months and by 0.3+/-0.7% between 4 and 10 months were observed (p<0.001) as well as a reduced requirement for diabetes medications. Age, duration of diabetes, glycated hemoglobin level, diabetes medications and weights changes were significant predictors of diabetes remission at 18 months. Analyses of secondary objectives show concomitantly with weight loss, a positive impact on arterial blood pressure, dyslipidemia and sleep apnea syndrome, associated with transient protein malnutrition. No changes in renal function were observed. Globally, no differences were found between the gastric bypass and the sleeve gastrectomy group during the follow-up. In conclusion, among obese patients with type 2 diabetes, at least 54% of remission rate is observed 18 months after bariatric surgery. The surgery reduces significatively the glycated hemoglobin levels as well as the requirement for diabetes medications. Further trials will be necessary to assess the durability of these results. De nombreuses études cliniques ont démontré l’efficacité de la chirurgie bariatrique dans le contrôle du diabète sucré de type 2. L’enjeu est de taille, vu la constate progression de la prévalence du diabète, maladie aux lourdes conséquences en termes de morbidités, de mortalité et de coûts pour la santé publique. L’objectif primaire de l’étude est l’évaluation de l’efficacité des différentes techniques de chirurgie bariatriques dans l’arsenal thérapeutique du diabète sucré de type 2. L’objectif secondaire est l’analyse des effets de la chirurgie sur les autres comorbidités liées à l’obésité. Pour répondre à ces questions, nous avons analysé rétrospectivement le dossier de 96 patients diabétiques de type 2 (le critère d’inclusion étant une HbA1c supérieure ou égale à 6.5% sans traitement ou supérieure ou égale à 6% avec traitement) ayant bénéficié d’une intervention bariatrique de type RYGB (N=75) ou SG (N=21) aux CUSL et suivis en consultation à 4+/-1 mois, 10+/-15 mois et 18+/-2 mois après l’intervention. La rémission du diabète a été définie sur base d’un HbA1c inférieure à 6.2% en l’absence de traitements médicamenteux. L’âge moyen au moment de l’intervention était de 52+/-10 ans et 57% des patients étaient de sexe féminin. Le poids moyen s’élevait à 119+/-24 kg et le BMI à 42.8+/-6.8 kg/m². L’HbA1c moyenne au départ s’élevait à 7.7+/-1.4 kg pour un durée estimée d’évolution de la maladie à 7+/-7 ans. Tous les patients ont bénéficié d’un suivi médical à 4 mois, 76% à 10 mois et 41% à 18 mois. A 18 mois, 54% de la population était en rémission, sans différence d’efficacité entre le TYGB et la SG (p=0.890), avec respectivement 55% et 52% de rémission. Une diminution de l’HbA1c de 1.4+/-1.2% à 4 mois et de 0.3+/-0.7% entre 4 et 10 mois était observée (p<0.001), parallèlement à une diminution du recours aux traitements médicamenteux du diabète. Le jeune âge au moment de l’intervention, une courte durée d’évolution de la maladie, une faible HbA1c, une thérapie modeste avant l’intervention et une perte de poids important à 4 mois étaient prédictifs de la rémission du diabète. L’analyse des objectifs secondaires de l’étude met en évidence, parallèlement à la perte de poids, un effet positif sur la tension artérielle, la dyslipidémie et le syndrome d’apnées du sommeil, au prix d’un déficit protéique aux temps post-opératoire précoces. La fonction rénale n’ pas été modifiée. Globalement, aucune différence d’évolution entre les patients opérés par RYGB ou par SG ne fut mise en évidence. En conclusion, chez les patients obèses diabétiques du type 2, une rémission du diabète sucré est observée chez au moins 54% des sujets 18 mois après une intervention bariatrique. La chirurgie diminue significativement le taux d’HbA1c ainsi que le recours aux traitements médicamenteux du diabète. Des investigations ultérieures seront nécessaires pour évaluer la durabilité de ces résultats.
