Title: the effectiveness of the magnetic ring (linx) device in managing reflux after sleeve gastrectomy; long term results: a seven-years¿ experience.Authors: abdelkader hawasli , shoshana hallowell.Citation cite: hawasli et al.Mini-invasive surg 2023;7:4.Doi: 10.20517/2574-1225.2022.64.First patient to have the mr device linx (ethicon j&j cincinnati, oh) placement to manage her reflux after sg was done in january 2015.Since then and until december 2021, surgeon implanted the mr device in seventeen patients to manage their reflux after sg, including fourteen females and three males, with a mean age of 54 ± 12 years.Their initial mean weight at the time of placement of the mr device was 180 ± 45 lbs.With a mean bmi of 31 ± 6 kg/m2.The mean time between their sg and the placement of the mr device was 41 ± 19 months.Our endpoint was complete resolution of reflux after > 3 years of implantation.All patients had pre-operative barium swallow, high-resolution esophageal motility and upper endoscopy with 48-hour ph monitoring using the bravo capsule.Reported complications included severe post-operative dysphagia (n=2) , patients developed a recurrent reflux (n=11), recurrent reflux due to a broken connection between the beads leading to an open mr device (n=3).In conclusion the mr device is a valuable tool in treating reflux after sg in spite of its potential risk of recurrence.Results can be interpreted as being dissatisfying if complete resolution is the goal.Larger studies, with more than 3 year follow up, are needed before a final decision is made on its value in the bariatric population.
