The purpose of this study is to find out more about the safety and effectiveness of the Laparoscopic Greater Curvature Plication (LGCP) procedure in patients with obesity and related problems such as diabetes, hypertension, high cholesterol, mild obstructive sleep apnea, and joint problems. LGCP is a less invasive weight loss surgery procedure than some of the other weight loss surgeries and it is possible that there are fewer risks with this procedure than with the other weight loss surgeries. LGCP is considered an experimental procedure and this study is being done to look at the long-term outcomes.
