Bariatric Surgical Program

St. Catherine of Siena Medical Center offers a broad range of bariatric surgical procedures to address your individual health and weight concerns and to ensure the optimal outcome for you and your family. Our programs provide patients with obesity screening, counseling, surgery and follow-up support.

Bariatric surgery is recommended in the case of morbid obesity, which is defined as excess body weight of 100 pounds or more or having a body mass index (BMI) of at least 40 kg/meters2. Morbid obesity is a contributing factor to multiple health problems, or co-morbidities including high blood pressure, diabetes, heart disease, and hyperlipidemia.

Weight Loss Surgery

Weight loss surgery at St. Catherine’s is performed using state-of-the-art laparoscopic techniques. This approach results in smaller incisions, shorter hospital stays, reduced post-operative pain and significantly faster recovery time from surgery.

  • Sleeve Gastrectomy: The sleeve gastrectomy is a gastric restrictive procedure designed to reduce the amount of food that a patient can eat by removing up to 85% of the stomach. The remaining stomach tissue is stapled together to form a tube which can hold between 1 to 2 ounces of food. An average size stomach can hold approximately 40 ozs.
  • Adjustable Gastric Band: Adjustable Gastric Band is a gastric restrictive procedure that consists of a hollow silicone band, tubing, and an access port. The hollow band is placed around the upper part of the stomach creating a small pouch above the band and a narrow passage into the larger remainder of the stomach. The narrowed opening between the stomach pouch and the rest of the stomach controls how quickly food passes from the pouch to the lower part of the stomach. Depending on the patient’s needs, after the device is implanted via the initial surgery, adjustments are made to tighten or loosen the band by adding or removing fluid inside the hollow band.  The doctor does this by injecting or removing the fluid through a small button-like part called the access port. This access port that is connected to the band by the tubing is placed under the skin in the abdominal wall.
  • Roux-en-Y Gastric Bypass (RYGB): The RYGB is a restrictive and malabsorptive procedure that limits the amount of food the stomach can hold while also limiting the amount of calories and nutrients absorbed. The procedure begins by dividing the stomach to create a small stomach pouch about the size of one’s thumb which holds about two ounces of food. The small intestine is divided where one end is brought up and joined to the small stomach pouch. The other end of the small intestine is re-joined back onto its own intestinal tract at a lower section.

Pre-Operative Care

Once you have a surgical date, our bariatric coordinators will contact you to set up a pre-operative educational appointment. At this time the coordinator will discuss your perioperative experience, which includes a review of post-operative expectations through discharge, nutrition education, discharge expectations and keys to long-term successes including lifestyle changes.

Our bariatric coordinators will also go over many of the most common questions regarding weight loss surgery such as:

  • How long is the hospital stay?
  • When can I go back to work?
  • When do I resume regular foods?
  • How long does it take before I get a surgical date?
  • How long is the surgery?
  • When can I start working out?
  • Does insurance cover this procedure?

Weight Loss Support Groups

St. Catherine of Siena Medical Center offers a bariatric support group that is supervised by a healthcare professional. It is open for anyone interested in learning more about bariatric surgery and the lifestyle you can expect afterwards. This program has proven to be an excellent, supportive and educational gathering for pre- and post-operative patients, with many patients who have had weight loss surgery openly sharing their personal stories and the issues they faced before and after their procedure. Topics of discussion can include protein drinks, healthy recipes, well-tolerated foods and exercise programs. We believe that the support group is one of the important tools needed to maintain a healthy and successful life post bariatric surgery. All are welcome and membership is free.
