Early Feasibility Study: Assessment of Self-Forming Magnetic Anastomosis Device and Delivery System (SFM) in Obese Patients, When Used to Create a Duodenal-Ileal Anastomosis Post SG (SNAP-PS), or Used to Create a Jejuno-Jejunal (J-J) Anastomosis

30 patients around the world

Available in Chile

This is a two-arm, single-center, early feasibility study to evaluate the use of the SFM Anastomosis System for creation of a duodenal-ileal (D-I) anastomosis in participants who have experienced inadequate weight loss following sleeve gastrectomy (SNAP-PS cohort) defined to be failure to achieve a minimum 50% EWL post sleeve gastrectomy or a patient undergoing a Roux-en-Y gastric bypass the SFM will be used to create the jejuno-jejunostomy. Adult male and female subjects between the ages of 18 and 65 years-old who are candidates for the primary or revisional surgery will be considered for participation. Patients appearing to meet basic eligibility criteria and who sign the study specific consent form will be screened for enrollment into this study and will be assessed by a multidisciplinary research team with pre-procedure nutritional and medical evaluation (including psychological and behavioral evaluation by an internist/bariatrician). Subjects meeting the inclusion and exclusion criteria and enrolled into the study will undergo a procedure in which the SFM device and delivery systems with create anastomoses between the duodenum and ileum or jejunum to jejunum.

Requirements for the patient

To 65 Years

All Gender

Medical requirements

: Age 18-65 years at screening
For the post sleeve gastrectomy diversion procedures (SNAP-PS)- Obesity with Body Mass Index (BMI) ≥ 40 kg/m2 but ≤ 55 kg/m2 at time of screening with or without comorbidities at time of screening. If subject has obesity-related comorbidities such as hypertension, dyslipidemia, and sleep apnea, these comorbidities must be well-controlled..
For the Roux-en-Y gastric bypass jejuno-jejunostomy procedure (J-J) - Obesity with Body Mass Index (BMI) ≥ 35.1 kg/m2 but ≤50 kg/m2 with or without comorbidities at time of screening. If subject has obesity-related comorbidities such as hypertension, dyslipidemia, and sleep apnea, these comorbidities must be well-controlled.
Able to understand and sign informed consent document
Patient lives, and intends to remain, within a 150-km radius of study center for 24 months
Willing to commit to sustained healthy behaviors that include diet, eating and exercise habits for the duration of the trial
Willing to refrain from smoking during the study follow-up period
If subject is female, she must commit to not becoming pregnant for 24 months and agree to use of contraceptives during this period and may not be nursing

: Known or suspected allergy to nickel, titanium or Nitinol
Type 1 Diabetes
Uncontrolled T2DM Fasting glucose ≥ 200 mg/dl (11.1 mmol/L) and/or hemoglobin A1c >10 or use of injectable insulin
Any documented conditions for which endoscopy and/or laparoscopy would be contraindicated or history of previous technically difficult or failed endoscopy
Contraindication to general anesthesia
Clinically significant finding during procedural endoscopy such as presence of an unhealed ulcers, bleeding lesions, tumors or ischemic or necrotic tissue at target magnet deployment site
Congenital or acquired anomalies of the GI tract, including atresias, stenosis, prior obstruction or malrotation
Presence of a duodenal diverticulum (>10mm)
Any previous major surgery on the stomach, duodenum, hepatobiliary tree (excluding laparoscopically removed gallbladder), pancreas or right colon
History of chronic gastrointestinal disease (e.g., cirrhosis, inflammatory bowel disease) that in the opinion of the Investigator may preclude safe and complete study participation
Uncontrolled severe hypertension (blood pressure >160/100mmHg)
Pre-existing severe comorbid cardio-respiratory disease (e.g., congestive heart failure, uncontrolled cardiac arrhythmia, coronary artery disease, chronic obstructive lung disease requiring supplemental oxygen, pulmonary embolism, Myocardial Infarction with prior 6 months)
Liver biochemistries (ALT and AST) ≥ 3 times the upper limit of normal
Uncorrectable coagulation disorder (platelets < 100,000, PT >2 seconds above upper normal limit or INR >1.5) at time of procedure, Note: management of anti-platelet medications, when applicable, will follow standard practices of the institution
Uncorrectable anemia (Hemoglobin < 11 g/dL in women and <12.5 g/dL in men)
Specific genetic or hormonal cause of obesity such as Prader -Willi syndrome
For females of child-bearing potential: Pregnancy or desire to be pregnant during the study
Concurrent condition anticipated to require MR imaging within the first 2 months after the study procedure
Diagnosed Bulimia Nervosa or Binge Eating Disorder (using DSM-5 criteria)
Physical or mental disability or psychological illness that in the opinion of the Investigator would be a contraindication for bariatric surgery
Subject is immunocompromised (e.g., active treatment for malignancies, hematologic malignancy, on immunosuppressive therapy, moderate or severe primary immunodeficiency, advanced or untreated HIV, active treatment with high-dose corticosteroids (i.e.,20 or more mg of prednisone or equivalent per day when administered for 2 or more weeks prior to surgery) or other immunosuppressive or immunomodulatory agents.
Subject has an active or suspected infection at the surgical site or a CDC Class 3/contaminated or Class 4/dirty-infected surgical wound.
Subject is not appropriate for inclusion in the clinical trial, per the medical opinion of the Principal Investigator"
Other prior or concurrent conditions that in the opinion of the Investigator would be unlikely to receive clinical benefit from the study procedure or participation in the study may compromise patient safety or study objectives such as the presence/diagnosis of a severe and evolutive life threatening pathology unrelated to obesity including but not limited to: ongoing infection, chronic pancreatitis, severe hepatic dysfunction, or renal dysfunction (GFR <60mL/min/1.73m2)
Any form of substance abuse or psychiatric disorder that in the opinion of the investigator could interfere with the conduct of the study
