An observational study in Surgery and Bariatric Surgery Candidate, sponsored by Unidad Internacional de Cirugia Bariatrica y Metabolica. Recruiting at 1 site in Venezuela. Open to participants aged 18 Years to 65 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2022-07-08.
Sponsored by Unidad Internacional de Cirugia Bariatrica y Metabolica · Observational
Magnetic devices have been successfully used in bariatric surgery. To the date the only reported use of the magnet was for liver retraction. This study is to demonstrate the safety and viability of using the magnetic system as a second surgical assistant in bariatric surgery and not only for liver retraction.
Patients undergoing primary laparoscopic sleeve gastrectomy (SG), one-anastomosis gastric bypass (OAGB), and Roux-en-Y gastric bypass (RYGB) or revisional surgery by single-port or port-reduced approach.
Also others procedures like Nissen/Sleeve gastrectomy or general surgery. The magnetic system can be used like a second assistant in the steps of the surgery for example: liver retraction, upper retraction of gallbladder, retraction of the stomach, upper retraction of jejuno-jejunal anastomosis performing a gastric bypass or closing mesenteric defects liker intermesenteric or Petersen´s defect.
Using the single-port device or port-reduced approach to obtain better aesthetic results.
Unidad Internacional de Cirugia Bariatrica y Metabolica is the lead sponsor of 4 studies on the registry; 2 are open to participants now.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Perform a bariatric surgery using the magnetic device like a second assitant in the steps of the surgery in order to perform the surgery with less incisions and with the same safety
Procedure: Magnetic Gastric Bypass · Procedure: Magnetic Sleeve Gastrectomy · Procedure: Revisional Bariatric Surgery · Procedure: Nissen/Sleeve Gastrectomy with Magnetic Assistance · Procedure: Mangetic General Surgery
Perform a gastric bypass with the magnetic grasper to do the liver retraction, upper retraction of the stomach, upper retraction of the jejuno-jejunal anastomosis, upper retraction of the mesocolon to close petersen defect or the jejuno-jejunal anastomosis to close the intermesenteric defect also to do the retraction of the omega limb and perform the section of the limb and finish the gastric bypass
Perform a sleeve gastrectomy with the magnetic grasper performing the liver retraction and the upper retraction of the stomach
Perform liver retraction and also steps of the surgery like upper retraction of the stomach, upper retraction of the jejuno-jejunal anastomosis, upper retraction of the mesocolon to close petersen defect or the jejuno-jejunal anastomosis to close the intermesenteric defect also to do the retraction of the omega limb, upper retraction of the stomach
Perform a nissen-sleeve gastrectomy with the magnetic grasper performing the liver retraction and the upper retraction of the stomach, retraction of the stomach to close the hiatal defect and perform a nissen funduplication before do the sleeve gastrectomy
Use the magnetic grasper to do the gallbladder retraction in cholecystectomies and upper retraction of the stomach to close the defect on hiatal hernia cases.
