Evaluation of current and newly developed endoluminal therapies in the management of Upper and Lower GI conditions.

Over the last few years there have been numerous advances in the use of endoscopic equipment and related treatments in the identification and intervention of gastrointestinal diseases. Many of these treatments using flexible endoscopes have either complimented or replaced surgical approaches to these same benign and malignant disease processes with the potential of being the standard of care for many of these clinical conditions. The initial primary focus of this study will be the use of endoscopic myotomy for achalasia, endoscopic treatment of post bariatric weight gain, endoscopic gastro-gastric fistula treatments, and other endoluminal therapies for gastrointestinal and post-operative conditions. These treatments have been validated by prior surgery studies.
