Endomina Controlled Study

Obesity

obesity, endoscopy, endoscopic sleeve gastroplasty

The aim of this trial is to evaluate the efficacy of an endoluminal vertical gastroplasty (EVG) using an endoluminal-suturing device. Safety will also be characterized, in particular by the incidence of all Adverse Device Effects (ADEs). A secondary endpoint is to compare a delayed treatment control group (diet alone; crossover at 6 months) with a treatment group (EVG plus diet). Other secondary endpoints include improvements in other obesity measures.

Surgery is currently the only effective treatment for morbid obesity and can be divided into restrictive surgeries (Lap Band and Sleeve gastrectomy), malabsorptive surgeries (Biliary pancreatic deviation and duodenal switch) or a combination of both (RYGBP). This latter technique is the most common and most effective surgical procedure performed worldwide and has been processed to be an effective treatment of morbid obesity and its complications, achieving excess weight loss of 65 to 80 %; 1-2 years after surgery. Vertical gastric plication is a novel surgical approach for reducing the stomach capacity. Anterior surface plication and greater curvature plication are variations of vertical gastric plication that reduce the gastric capacity through infolding of the anterior surface or greater curvature of the stomach, respectively. These approaches have been tested, with positive results. A transoral or endoluminal approach (i.e. a procedure that requires no incision, because access is granted through the mouth) offers the potential for additional benefit to the patient, because the procedures continue to become more and more minimally invasive. Advances in endoluminal devices are now allowing clinicians the ability to begin exploring bariatric procedures performed via flexible endoscopy. Although these procedures may not be as effective as their surgical counterparts, these less-invasive options may relieve patients of the significant risks associated with surgery and might become part of the armamentarium of obesity management. Endomina (Endo Tools Therapeutics, Gosselies, Belgium) is a CE marked device that may be attached to an endoscope inside the body and allows remote actuation of the device during a peroral intervention. It offers the possibilities of making transoral full thickness tissue apposition and may allow performing, via a transoral route, large plications with tight serosa to serosa apposition. After a first trial on pigs (safety), a second trial on human patients was performed. This trial included 11 patients treated with the same technique. There were no complications and the short term results were encouraging with 41% EWL at 6 month. A multicentric trial NCT02582229 entitled: A Prospective Study to Evaluate the Efficacy of an Endoluminal-suturing Device (Endomina TM) as an Aid for Endoscopic Gastric Reduction. is ongoing and inclusion of patients ended in December 2016 with a total of 51 patients included in 3 European centers. Early results of the trial had showed that dietician follow-up is an important part of the success. During that time implementation of the procedure had been done. The aim of this trial is to compare a control group (diet alone) with a treatment group (Endomina procedure plus diet).
