Magnetic Sphincter Augmentation for Gastroesophageal Reflux Disease

Magnetic sphincter augmentation is an effective and safe surgical method for the treatment of gastroesophageal reflux disease (GERD). The device has been compared with twice-daily proton pump inhibitor therapy and laparoscopic fundoplication (in randomized trials and prospective cohort studies, respectively). Magnetic sphincter augmentation was superior to medical therapy and equivalent to surgery for the relief of GERD symptoms. Recent research focuses on implanting the device into more complex patients, such as those with larger hiatal hernias or those with Barrett ’s esophagus. Additional novel research topics include cost analysis and predicting and minimizing postoperative dysphagia.

Conclusions: The success of robotic fundoplication depends on adhering to a few important technical principles. In our experience, the robotic surgical treatment of gastroesophageal reflux disease with large paraesophageal hernias may afford the surgeon increased dexterity and is feasible with comparable outcomes compared with traditional laparoscopic approaches.

Abstract Robotic-assisted surgery for benign esophageal disease is described for treatment of achalasia, gastroesophageal reflux, paraesophageal hernias, epiphrenic diverticula, and benign esophageal masses. Robotic Heller myotomy has operative times, relief of dysphagia, and conversion rates comparable to laparoscopic approach, with lower incidence of intraoperative esophageal perforation. The use of robotic platform for primary antireflux surgery is under evaluation, due to prolonged operative time and increased operative costs, with no differences in postoperative outcomes or hospital stay. Studies have shown b...

AbstractBackgroundOAGB-MGB emerged as a standard procedure, albeit RYGB remains the most frequently performed gastric bypass. Comparative studies are scarce.MethodsProspectively collected data (July 2006 to November 2017) from a large sample size and adequate follow-up were analyzed using logistic regression and linear mixed models. Total weight loss (TWL) within the first 3 years was defined as primary outcome and duration of operation, perioperative, and late complications and comorbidity remission as secondary outcomes.ResultsThree hundred twenty-four OAGB-MGBs (age 42.51 ± 11.36 years, 74.69% females) presented ...

Gastroesophageal reflux disease (GERD) is common in the morbidly obese population, and hiatal hernias are encountered in 20% to 52% of patients. Primary surgical repair of hiatal hernias, in particular the paraesophageal type, is associated with a higher recurrence rate in obese patients. Concomitant weight loss surgery may be advisable. Combined sleeve gastrectomy and paraesophageal hiatal hernia repair is feasible but can induce or worsen preexisting GERD. A Roux-en-Y gastric bypass offers advantages of more pronounced excess weight loss and better symptom control, albeit with a potentially higher rate of morbidity compa...

This study examined the safety and efficacy when repairing defects in 2 anatomical structures (hiatus and lower esophageal sphincter) in a concomitant set of procedures in patients with hiatal hernias between 2 and 5 cm. Methods. Prospective data were collected from 99 patients who underwent hiatal hernia repair followed immediately by the TIF procedure (HH + -TIF). GERD-HRQL (Health-Related Quality of Life), RSI (Reflux Symptom Index), and GERSS (Gastroesophageal Reflux Symptom Score) questionnaires were administered before the procedure and mailed at 6 and 12 months. Results. Ninety-nine patients were enrolled, and all w...

CONCLUSION: LVG mildly increases GER, which is likely related to the development of hiatal hernias and a decrease in LES pressure and esophageal sweep. However, LVG should not be contraindicated for patients with preoperative pH-metric GER, as this may clear after the procedure. PMID: 31257899 [PubMed - as supplied by publisher]

Purpose of review To examine current trends and research in nonmedical approaches to the treatment of gastroesophageal reflux disease (GERD). Recent findings Long-term studies of GERD patients treated with transoral incisionless fundoplication (TIF) have found that a large portion of patients resume proton pump inhibitor therapy. In patients with uncomplicated GERD, magnetic sphincter augmentation (MSA) shows excellent short-term results in both patient satisfaction and physiologic measures of GERD, with fewer postoperative side-effects than fundoplication, although dysphagia can be problematic. Summary Fundoplicat...

AbstractBackgroundCurrent literature is conflicted regarding the efficacy of laparoscopic anti-reflux surgery (LARS) among obese patients complaining of pathologic reflux or otherwise symptomatic hiatal hernias. Controlling for other factors, this study examined the influence of preoperative body mass index (BMI) on clinical and subjective quality of life (QOL) outcomes following LARS.MethodsPatients who underwent LARS between February 2012 and April 2018 were subdivided into four BMI stratified categories according to CDC definitions: normal (18.5 to
