StomaphyX is a new and innovative revision procedure for individuals who have had Roux-en-Y gastric bypass surgery and have regained weight due to a stretched stomach pouch or enlarged stomach outlet. Approved by the US FDA in 2007, the StomaphyX procedure reduces the stomach pouch and stomach outlet (stoma) to the original gastric bypass size without traditional surgery or incisions and with minimal recovery time. It is not performed as a primary method of weight loss surgery, but as a type of revisional bariatric surgery for gastric bypass patients.
