About this study
The purpose of this study is to evaluate the feasibility, safety, and tolerability of endoscopic selective gastric mucosal ablation (GMA) using argon plasma coagulation after sleeve gastrectomy. In this study, GMA will be performed on patients who have experienced weight regain following an initial successful response to sleeve gastrectomy.
Read the detailed description
Obesity is a multifaceted chronic disease associated with substantial morbidity and mortality, leading to conditions like diabetes, cardiovascular diseases, and malignancies. Bariatric procedures, such as the sleeve gastrectomy, stand out as the current most effective long-term treatments for obesity. Despite its effectiveness, a significant number of patients experience weight regain during long-term follow-up. Endoscopic minimally invasive bariatric intervention has been proposed as a viable, safe, and effective option for the treatment of weight regain after SG. Gastric mucosal ablation (GMA), in particular, is hypothesized to be a safe and effective endoscopic revisional treatment for weight regain following sleeve gastrectomy based on previous positive pre-clinical and clinical studies. To investigate the feasibility, safety, and tolerability of GMA after sleeve gastrectomy, a single procedure is designed to ablate the gastric mucosa of the pseudo greater curvature created after the sleeve gastrectomy in a single endoscopic session. We hypothesize that endoscopic selective ablation of the gastric mucosa after sleeve gastrectomy is effective as a revisional treatment for weight regain and will result in significant metabolic improvements.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percent Change in Total Body Weight Loss (TBWL) from Baseline
Measure percent change in total body weight over time following endoscopic GMA. TBWL = pre-op weight - post op body weight. % TBWL is the fraction of body weight expressed in percentage term
Measured: 6 Months
Secondary outcomes (8)
Rate of Safety Complications according to Clavien-Dindo Classification
Occurrence of complications according to the Clavien-Dindo classification
Measured: Month 1, Month 2, Month 3, Month 4, Month 6, Month 7, Month 8, Month 9, Month 10, Month 11, Month 12
Rate of Adverse Events (AE)
Occurrence of Adverse Events along with AE Type, severity, and relationship to treatment.
Measured: Month 1, Month 2, Month 3, Month 4, Month 6, Month 7, Month 8, Month 9, Month 10, Month 11, Month 12
Post-operative Pain Assessment
Visual Analog Scale pain score at baseline compared to postoperative follow-up visits. The VAS Pain Scores range from 0 (minimum) to 10 (maximum), where 0 represents no pain and 10 represents the maximum level of pain, with higher scores indicating greater intensity of postoperative pain.
Measured: Month 1, Month 2, Month 3, Month 4, Month 6, Month 7, Month 8, Month 9, Month 10, Month 11, Month 12
Percent Change in Total Body Weight Loss (TBWL) from Baseline
Measure percent change in total body weight over time following endoscopic GMA. TBWL = pre-op weight - post op body weight. % TBWL is the fraction of body weight expressed in percentage term
Measured: Month 12
Quality of Life Assessment
Baseline quality of life assessment scores compared to 6 Month quality of life assessment scores. Quality of life score assessed and measured by the 36-Item Short Form Survey and The Impact of Weight on Quality of Life-Lite questionnaires. Scoring for both questionnaires range from 0 (minimum) to 100 (maximum). Higher scores for both questionnaires indicate higher quality of life.
Measured: 6 Months
Glucose Homeostasis Assessment
Baseline measured fasting glucose, HOMA-IR, and HbA1c levels compared to post-intervention fasting levels at 3 Months and 6 Months using laboratory testing.
Measured: 3 Months, 6 Months
Serum Levels of Lipids Assessment
Baseline compared to post-intervention fasting serum lipids levels at 3 Months and 6 Months measured by laboratory testing.
Measured: 3 Months, 6 Months
Gastric Sensory Function Assessment
Volume to comfortable fullness and Maximum Tolerated Volume measured using a visual analog scale at 3 Months and 6 Months. Volume to Comfortable Fullness and Maximum Tolerated Volume scores both range from 0 (minimum) to 100 (maximum) with a lower score indicating a smaller required volume to reach comfortable fullness and maximum fullness.
Measured: 3 Months, 6 Months
