Overview

The purpose of this research is to gather information on the safety and effectiveness of Endoscopic Sleeve Gastroplasty (ESG) for weight loss in a population of obese ulcerative colitis (UC) patients undergoing colectomy with eventual Ileal Pouch Anal Anastomosis (IPAA) compared to counseling on diet and lifestyle interventions alone.

• Willing to adhere to the diet and behavior modifications required for ESG
• Able to follow the visit schedule
• Able to provide informed consent
• If female, be either post-menopausal, surgically sterile, or agree to practice birth control during year of study and have negative serum Human Chorionic Gonadotropin (HCG) at screening/baseline

• Prior gastric or bariatric surgery or other alteration to upper gastrointestinal anatomy which would preclude safe or technical performance of ESG
• Current or recent (last six months) gastric or duodenal ulceration
• Esophageal or gastric varices
• Significant motility disorder of the esophagus or stomach
• Large hiatal hernia measuring >5 cm or ≤ 5 cm and associated with severe gastroesophageal reflux
• Severe coagulopathy, hepatic insufficiency, or cirrhosis
• Gastric mass
• Presence of any other medical condition which precludes safe performance of elective endoscopy such as poor general health and/or history of severe hepatic, cardiac, or pulmonary disease
• Serious or uncontrolled psychiatric illness which may compromise patient understanding of procedure or compliance with follow-up visits
• Unwilling to participate in an established diet and behavior modification program, with routine follow-up
