HybridAPC for Gastric Mucosal Ablation in Obese Patients.
Feasibility and Safety of HybridAPC for Gastric Mucosal Ablation in the Management of Patients With Obesity.
This study is intended to investigate safety and feasibility of a new weight loss technique called Gastric Mucosal Ablation (GMA) that does not require surgery, but can be achieved using an endoscopic procedure.
Previous studies have suggested that weight loss after vertical sleeve gastrectomy (VSG) is partly due to the removal of normal stomach tissue suspected of having hormonal function. The study will investigate the minimally invasive treatment of obese participants by means of argon plasma coagulation (APC) in combination with waterjet submucosal injection using HybridAPC.
As primary endpoint the % total body weight loss (TBWL) will be determined as body weight difference at the final 6 months FU after the last treatment session in comparison to the body weight prior to the initial treatment.
After signing the informed consent the doctor and research team will determine if the participant meets all requirements for this study. If a participant is confirmed to be a suitable candidate additional tests will be performed prior to the first application of GMA to assess the health status of the participant prior to treatment. During the screening and baseline visit the medical history and the medications of the participant will be reviewed.
After the treatments the participants will be followed for up to 6 months to assess the outcome of the GMA procedure.

- Known history of a structural or functional disorder of the esophagus, including any swallowing disorder, esophageal chest pain disorders, or drug refractory esophageal reflux symptoms.

- Currently have ongoing symptoms suggestive of intermittent small bowel obstruction, such as recurrent bouts of post-prandial abdominal pain, nausea or vomiting.
- Active H. pylori infection (Subjects with active H. pylori may continue with the screening process if they are treated with an appropriate antibiotic regimen, and eradication has been confirmed).
