Endoscopic Sleeve Gastroplasty With Endomina® for the Treatment of Obesity in Kidney Transplant Candidates

Study Overview
=================
Brief Summary
-----------------
The aim of this pilot prospective interventional study is to evaluate the efficacy of endoscopic sleeve gastroplasty (ESG) in allowing obese subjects (≥35 kg/m2) with end stage renal disease who need of kidney transplantation to reduce their BMI below 35 in order to be inserted in the waiting list BMI. The main question[s] it aims to answer are: Is the procedure effective in reducing BMI to the target level in 12 months? Which is the effect on weight loss, quality of life and obesity-related comorbidities? Participants will undergo ESG as per standard clinical practice and followed up to 12 months before transplantation and for 12 months after transplantation.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: kidney transplant candidates with obesity (BMI > 35 kg/m2)<br>Subjects with an indication to kidney transplantation that are not listed because of a high BMI according to the policy of the transplant Centre (cut-off 35 kg/m2) | Procedure: Endoscopic Sleeve Gastroplasty (ESG)<br>* ESG will be performed under general anaesthesia with orotracheal intubation. The Endomina® suturing system (EndoTools Therapeutics S.A., Gosselies, Belgium) mounted on a single channel endoscope (GIF-H190/GIF-HQ190; Olympus Medical Systems Corp., Tokyo, Japan) will be used. This system allows to obtain full thickness gastric sutures through the gastric wall of the gastric body, leaving the antrum and the gastric fundus free. The ESG starts with the reduction of the gastric body, suturing from distal to proximal and starting from the notch of the angulus and ending at the level of the fundus. 4-8 full thickness stitches will be placed, with 2 passes per stitch. The final effect of ESG is the creation of a gastric tubule thus reducing the volume of the stomach. After the procedure, the final shape will be evaluated, to examine any gaps that would require additional closure, and to exclude bleedings and/or other complications.<br>|
