Background summary
Obesity is defined as having a Body Mass Index (BMI) of 30 kg/m² or higher.
Obesity has become one of the most significant health problems in the world.
Worldwide obesity nearly triples between 1975 and 2016, and is predicted to
continually increase in the future. In 2016, more than 1.9 billion adults were
overweight; and of these over 650 million were obese.
Diet, exercise, and behavior modification program(s) provide non-surgical
treatments for obesity; however, success rates of long-term weight loss
maintenance with lifestyle changes are low, ranging from 4%-8%.
To date, mainly gastric bypass surgery and sleeve gastrectomy surgery are
proven effective, long term treatment for obesity. However, less invasive
interventions are being considered to explore other ways to provide treatment
of obesity without the high risks associated with surgery. This will provide
treatment options to meet the needs of the millions of individuals who cannot
or are not willing to undergo surgical intervention.
Study objective
To assess the safety and effectiveness of the LGV in treating obese subjects
with a BMI of 35 kg/m2 to 55 kg/m2 who have failed one or more conservative
weight-reduction alternative(s), such as supervised diet, exercise, and
behavior modification program(s).
Study design
Investigative, prospective, non-randomized, multi-center study to assess the
safety and effectiveness of the LGV for a duration of 24 months.
Intervention
The Laparoscopic Gastric Vest (LGV), branded the ReShape Vest*, is a long-term,
silastic, implantable system that is placed around the stomach to encompass the
gastroesophageal junction to the Incisura Angularis.
The intervention is the implantation of the LGV.
Study burden and risks
Possible General Risks of Anesthesia and Weight Loss Surgeries:
- Abnormal Stools
- Acute Cholecystitis/Gallstones
- Adverse reaction to anesthesia
- Bleeding
- Blood clots
- Cardiac Arrhythmias
- Gastritis
- Death/Cardiac arrest
- Dehydration
- Esophagitis
- Excess gas (cramps, bloating, gassiness)
- Excessive or inadequate weight loss
- Gastroesophageal reflux (GERD)
- Fatigue
- Hernia (hiatal or other)
- Hypoglycemia
- Inflammation
- Indigestion
- Infection
- Injury to the stomach, liver, intestine or other organs due to surgery
- Leaks in the gastrointestinal system
- Loss of appetite
- Lung or breathing problems
- Malnutrition
- Nausea and vomiting
- Obstruction, bowel
- Obstruction, stomach
- Pain
- Pancreatitis
- Perforation
- Psychosocial and sexual malfunction
- Redundant Skin
- Ulceration
Possible Risks of Study Device and/or Procedure:
- Device Malfunction
- Dilation of the esophagus
- Dysphagia (difficulty swallowing)
- Erosion of the stomach or esophagus
- Proximal or distal pouch dilation
- Device slippage
- Suture failure
- Suture perforation
- Weight gain due to noncompliance of patient
Gastric Leaking:
Gastric leaking occurs when digestive juices and partially digested food leak
into the cavity surrounding the stomach. Gastric leaking may be associated with
the following signs and symptoms:
- Tachycardia (rapid heart rate)
- Oscillating heart rate
- Fever
- Hiccups
- Back left shoulder or epigastric pain (pain right below your ribs)
- Nausea
- Dyspnea (difficult or labored breathing) or shortness of breath
- Bloody saliva
- Elevated white blood cell count (potential sign of an infection)
- Shortness of breath
Device Failure:
The minimum tested lifetime of the Vest is 10 years. Should the device*s
integrity and/or function deteriorate over time, the subject should discuss
alternative treatment options with the study doctor. Options may include a
revision surgery to remove the LGV.
Reoperation/Device Removal:
Decisions to remove the LGV may be required which could lead to adhesions,
making the explantation of the device difficult and complicated. Rapid weight
loss could result in complications that may require additional surgery or
device removal.
