If you receive bariatric surgery at ProMedica Toledo Hospital, your physician will recommend either Roux-en-Y gastric bypass or gastric sleeve resection.
Roux-en-Y Gastric Bypass
Roux-en-Y gastric bypass is the operation most performed in the United States to induce weight loss. Most patients will lose about 75% of their excess weight in 12 – 18 months post-surgery. A weight loss of 60 – 70% is generally maintained.
During surgery, a small pouch is created at the top of the stomach using staples. The volume of the pouch is less than one ounce. This pouch is then attached to a limb of the small intestine so that food bypasses the stomach and the first part of the small intestine. The operation works because the patient feels full with smaller amounts of food.
Additionally, food absorption is inhibited and hormonal changes occur which temporarily suppress the appetite.
Gastric Sleeve Resection
Gastric sleeve resection is preferred in patients who have serious small bowel problems, such as Crohn’s disease. This operation removes the left side of the stomach leaving a thin tube – or “sleeve” – down the right side. In short-term follow-up studies, weight loss with the sleeve resection is slightly less than with gastric bypass. However, if longer term studies demonstrate stable weight loss, this procedure will be a reasonable option for many patients.
Regardless of the procedure your physician suggests, 99% of all bariatric surgeries at ProMedica Toledo Hospital are performed laparoscopically. Laparoscopic surgery is a form of minimally invasive surgery, which means that smaller incisions are used so that healing time is faster. Laparoscopic surgery generally means less pain and scarring, decreased blood loss and reduced risk of infection compared to traditional surgery techniques.
