Index Endoscopic Restrictive and Other Devices in Obesity Treatment: Techniques and Outcomes
This chapter describes the major intragastric endoscopic restrictive devices currently in use and in development to aid in weight loss for the obese patient. By far the most commonly used and prolific of these devices is the intragastric balloon, of which three types are now FDA approved in the USA, with others available internationally. Many thousands of patients have had such balloons placed, usually for up to 6 months per balloon. Other devices approved for gastric suturing have been adapted for weight reduction procedures, such as the endoscopic sleeve gastroplasty. Space-occupying products of other types, including stents, expanding ingested beads, and devices which partially obstruct the pylorus are also described.
