Endoscopic Suture Gastroplasty (ESG) for Treatment of Obese Patients With Endometrial Cancer

Prior treatment

• Prior gastrointestinal surgery with sequelae, i.e., obstruction, and/or adhesive peritonitis or known abdominal adhesions
• Prior open or laparoscopic bariatric surgery
• Prior surgery of any kind on the esophagus, stomach, or any type of hiatal hernia surgery
• Use of an intragastric device prior to this study due to the increased thickness of the stomach wall preventing effective suturing
• Patients who are unable or unwilling to take prescribed proton pump inhibitor medication
• Patients receiving daily prescribed treatment with high dose aspirin (\> 80 mg daily), anti-inflammatory agents, anticoagulants, or other gastric irritants
• Subjects who are taking corticosteroids, immunosuppressants, and narcotics

• Potential upper gastrointestinal bleeding conditions such as esophageal or gastric varices, congenital or acquired intestinal telangiectasis, or other congenital anomalies of the gastrointestinal tract such as atresia or stenoses
• Gastrointestinal stromal tumors, history of premalignant gastric lesions (advanced atrophic gastritis), history of familial and non-familial adenomatous syndromes
• Achalasia or any other severe esophageal motility disorder
• Subjects with any serious health condition unrelated to their weight that would increase the risk of endoscopy
• Motility disorders of the GI tract such as gross esophageal motility disorders, gastroparesis, or intractable constipation
• Hepatic insufficiency or cirrhosis
• Subjects with Severe cardiopulmonary disease or other serious organic disease which might include known history of coronary artery disease, Myocardial infarction within the past 6 months, poorly controlled hypertension, required use of NSAIDs
