The lap Roux-en-Y gastric bypass operation is one of the most common gastric bypass surgeries. Lap Roux-en-Y gastric bypass is both a restrictive and a malabsorptive procedure. It alters digestion by limiting the amount and types of foods that you can eat. It can be performed through open surgery with one long incision or laparoscopically using multiple small incisions.
With the lap Roux-en-Y gastric bypass procedure, a small stomach pouch is created by using special staples or a vertical gastric band. This pouch is then connected to a Y-shaped segment of your small intestine which allows food to bypass the lower section of your stomach and the first segments of your small intestine. Not only is your stomach pouch too small to hold large amounts of food, but by skipping segments of your small intestine, fat absorption is substantially reduced resulting in weight loss.
On average, the lap Roux-en-Y gastric bypass surgery takes one to four hours of operating time. Most patients remain in the hospital one to three days. Some may stay longer, but it’s not an indication of how well the recovery may be going. As with any surgery, there are some risks involved with the lap Roux-en-Y gastric bypass procedure, but your surgeon will discuss these with you in detail before your procedure. There is also a detailed follow-up plan for all bariatric surgeries including the lap Roux-en-Y gastric bypass.
