A Prospective Study to Evaluate the Suture Pattern With the Endomina Suturing Device for Endoscopic Sutured Gastroplasty (ESG).
- Conditions
- Obesity

- Device: Endomina
- Registration Number
- NCT03843801
- Lead Sponsor
- Erasme University Hospital
- Brief Summary
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 (1).
Endomina (Endo Tools Therapeutics, Gosselies, Belgium) is CE mark device that may be attached to an endoscope inside the body and allows remote manipulation of the arms of the device during a peroral intervention. It offers the possibilities of making transoral surgical full thickness sutures and may allow performing endoscopic therapeutic interventions, via a transoral route.
A first trial including 11 patients assessed feasibility and safety of the technique (2). There were no complications and the short-term results were encouraging. Then a multicentric efficacy study was conducted, including 51 patients (3). The results where EWL of 31% at one year and TBWL of 9% without complications.
Finally a randomized controlled study was done including 73 patients in a 2/1 randomized fashion with a crossover at 6 months. Treated group was with the endomina device and controlled group was diet only. The follow-up was the same in each group. Primary endpoint was to reach the ASGE guideline "difference between a control group and a treatment group of minimum 15%" (4).
Technique and suture pattern have evolved since the first study. The aim of this prospective evaluation is to compare different suture patterns and their mechanism of action.

Group Intervention Description Gastric emptying reduction Endomina Intragastric sutures are done to slower the gastric emptying Volume reduction Endomina Intragastric sutures are done to reduce the volume of the stomach Increasing distension Endomina Intragastric sutures are done to maximalize the gastric distension
- Primary Outcome Measures
Name Time Method Weight loss one year from procedure no difference in weight loss between groups
- Secondary Outcome Measures
Name Time Method sutures one year from procedure Evaluation of the correlation between the number of remaining sutures (with gastric remodeling) and weight loss
Excess weight loss one year from procedure Percentage of patients, total and per group, reaching ASGE guidelines of 25% Excess weight loss at 1-year
Gastric emptying one year from procedure Evaluation of the correlation between gastric emptying scintigraphy results and the suture pattern related to motility disruption
Satiety test assessed by the correlation between satiety test and the suture pattern related to volume reduction one year from procedure Evaluation of the correlation between satiety test and the suture pattern related to volume reduction
