Bariatric surgery

Our bariatric surgeons offer hope to people who are severely overweight (obese) and cannot lose weight on their own. Bariatric surgery limits how much food your stomach can hold, so you feel full after eating smaller portions. Some procedures limit the number of calories you absorb into your body.

We offer many options, including sleeve gastrectomy, gastric bypass (Roux-en-Y Gastric Bypass), BPD-DS (Biliopancreatic Diversion with Duodenal Switch), minimally invasive revisional bariatric surgery, management of lap adjustable gastric band and gastric balloon.

Patients can see bariatric providers at Geisinger Medical Center; Geisinger Montoursville; Geisinger Wyoming Valley; Geisinger Mt. Pleasant in Scranton; Gray's Woods in State College; Geisinger Holy Spirit; Geisinger Lewistown Hospital; and AtlantiCare - A member of Geisinger.

What types of bariatric surgeries are available to me?

Our bariatric surgical team specializes in minimally invasive (laparoscopic) surgery, which involves small incisions using tiny instruments and a camera to guide the surgery. Some patients may elect to have minimally invasive robotic bariatric surgery. Smaller incisions mean you’ll have less scarring, reduced pain, fewer complications and a quicker recovery. Our team will work with you to determine they type or procedure best meeting your needs and goals.

  • Gastric Bypass (Roux-en-Y Gastric Bypass): In a Roux-en-Y gastric bypass, a surgeon creates a stomach pouch that causes the food to go straight from the pouch to the small intestine.
  • Sleeve gastrectomy: Also known as a gastric sleeve, this involves the removal of most of the stomach, leaving only a narrow portion of the upper section of the stomach.
  • BPD-DS (Biliopancreatic Diversion with Duodenal Switch): Reduces the size of the stomach and also allows food to bypass part of the small intestine so fewer calories are absorbed.
  • Gastric balloon: A balloon placed without incisions for short-term weight loss.
  • Minimally invasive revisional bariatric surgery: Our surgeons can usually treat problems associated with previous bariatric procedures using minimally invasive techniques.
  • Management of Laparoscopic adjustable gastric bands
  • Adolescent Bariatric Surgery: Some teenagers with severe medical problems associated with obesity may be candidates for bariatric surgery. We have a team of providers with expertise in both pediatrics and obesity to care for adolescents.
