Minimally Invasive Procedures for Weight Loss

DESCRIPTION

Minimally invasive procedures involving a variety of gastrointestinal devices and techniques are being investigated for individuals who are morbidly obese, have diabetes and/or as a primary bariatric procedure. They are also used as a revision procedure (i.e., to remedy large gastric stoma or large gastric pouches) and for those who have regained weight following weight loss surgery. Endoluminal (also called endosurgical, endoscopic, or natural orifice) bariatric procedures access the stomach through the mouth without skin incisions. Examples of endoluminal bariatric devices or procedures include a duodenojejunal sleeve or liner, intragastric balloons, endoscopically-placed gastrostomy tube with an aspiration device, and/or gastric plication procedures.

The implantable duodenojejunal sleeve or liner (e.g., the EndoBarrier® Gastrointestinal Liner) is an impermeable fluoropolymer tube that will allow partially digested food leaving the stomach to move through the gastrointestinal tract without mixing with digestive enzymes or allowing nutrients to be absorbed. Under general anesthesia, the liner is deployed through a catheter, anchored within the duodenum and left in place. The device can be removed endoscopically by using the liner drawstrings to collapse and retract the anchor barbs.

Intragastric balloons [e.g. Silimed™, ReShape Duo™, BioEnterics® Intragastric Balloon (BIB) or Obalon System] are placed in the stomach using an endoscope or swallowed to act as a space-occupying device. They are either a single balloon or two connected balloons that once in place, are filled with saline or air. Complications include problems with erosion and migration, and long term weight loss is variable.

Endoscopically-placed gastrostomy tube with an aspiration device (e.g. AspireAssist®) is similar to a percutaneous endoscopic gastrostomy (PEG) tube, with a detachable external device through which patients partially drain their gastric contents into a toilet after a meal. The device is readily reversible and intended for long-term duration of use.

Gastric plication procedures, also known as endoscopic gastroplasty procedures include several restrictive suturing or stapling techniques that do not leave devices behind.  In one, the greater curve plication or total vertical gastric plication of the stomach is accessed endoscopically and numerous pleats or imbrications are created to reduce the volume of the gastric cavity. The pleats are sutured or stapled in place (e.g., EndoCinch™, StomaphyX™, EsophyX™, and NDO Plicator™). The StomaphyX™ procedure is also used as a revision procedure for individuals who have had the Roux-en-Y gastric bypass surgery and have regained weight. Another, the Transoral Gastric Volume Reduction (TGVR) is a relatively new restrictive procedure that works by sewing the sides of the stomach to create a feeling of fullness. The Primary Obesity Surgery Endolumenal (POSE™) procedure is for those who have not had weight loss surgery in the past and are seeking more conservative weight loss results. It reduces the size of the stomach by creating folds and anchoring them in place with sutures.

The ROSE (restorative obesity surgery endoluminal) procedure is another example of a minimally invasive bariatric procedure. This incisionless surgery reduces stomach volume and stoma diameter, which is designed to increase restriction and encourage weight loss in gastric bypass patients.

ADDITIONAL INFORMATION

The published evidence from peer-reviewed literature on minimally invasive bariatric surgery procedures is insufficient to form conclusions on their impact on health outcomes. While the short-term weight loss is similar to gastric bypass, the complications rates, especially nutritional complications, may be higher. Long-term safety data is either not available or conflicting. Therefore, these procedures remain investigational.
