    Author: Kristensen SD, Naver L, Jess P, Floyd AK.
    Journal: Dan Med J; 2014 Jun; 61(6):A4854. PubMed ID: 24947625.
    Abstract:
    INTRODUCTION: The aim of this study is to evaluate the benefits and disadvantages of closing the mesenteric defects during gastric bypass to avoid internal herniation (IH). MATERIAL AND METHODS: The study is performed as a single-centre, randomised, controlled, blinded trial. Patients are randomly assigned to either conventional laparoscopic Roux-en-Y gastric bypass (LRYGB) without closing the mesenteric defects (n = 250) or RYGB with closing of the defects with hernia clips (n = 250). Follow-up is conducted at six months, one year, two years and five years after RYGB. The primary endpoint is the incidence of IH. CONCLUSION: This study will be the first Danish, randomised, controlled study comparing conventional LRYGB with and without closure of the mesenteric defects. The results will contribute to evidence-based recommendations for the prevention of IH. FUNDING: not relevant. TRIAL REGISTRATION: The study was registered with the Danish Data Protection Agency (SN-10-2012) and The Central Denmark Regional Committees on Biomedical Research Ethics (1-01-83-0209-12, SJ-284). The study is registered with clinicaltrials.gov: NCT01595230.
