Bariatric Surgery

Bariatric Surgeries at St. Joseph’s Health are performed in a state of the art operating room by highly-skilled, board-certified, experienced surgeons. Services St. Joseph’s provides to qualified patients include:

  • Laparoscopic Roux-en-Y Gastric Bypass
  • Laparoscopic Adjustable Gastric Band

These procedures are done through small incisions in the upper abdomen. Each prospective patient is evaluated by one of our surgeons in a one-to-one consultation. The type of surgery will be determined during the consultation based on what is most appropriate for the individual patient.

We offer a distinctive multidisciplinary approach which focuses on meeting the patient’s needs through every step of the process. Services for our bariatric surgery patients include; seminars, individual consultations with the surgeon, assistance with insurance approval, preparation classes before the surgery and continuous support group meetings after the procedure to ensure the best possible outcome. We will work together to ensure that your pathway to surgery goes smoothly. Candidates include those who:

Bariatric Surgery Services Available

Laparoscopic Adjustable Gastric Band

Laparoscopic Adjustable Gastric Band is a restrictive surgical procedure; it works by limiting the amount of food that can be eaten at one time. During this procedure, two medical devices are implanted in the patient: a silicone band and an injection port. The silicone band is placed around the upper part of the stomach and molds the stomach into two connected chambers. The injection port is attached to the abdominal wall, underneath the skin. The port is connected to the band with soft, thin tubing.

The band is adjustable. Adjustments are made by your healthcare professional using a needle to inject saline solution into your band through the port. Adding saline increases the amount of restriction provided by the band, helping patients feel fuller sooner and with less food.

Laparoscopic Roux-en-Y Gastric Bypass Surgery

Laparoscopic Roux-en-Y Gastric Bypass surgery uses a combination of restriction (limiting the amount of food that can be eaten at one time) and malabsorption (bypassing a portion of the small intestine means the patient’s body absorbs fewer calories). During the procedure, the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a large portion of the small intestine, which absorbs calories and nutrients. Having the smaller stomach pouch causes patients to feel fuller sooner and eat less food.

Laparoscopic Sleeve Gastrectomy

The Sleeve Gastrectomy is a restrictive procedure. It works by limiting the amount of food that can be eaten at one time. During this procedure, the surgeon creates a small, sleeve-shaped stomach. It is larger than the stomach pouch created during Roux-en-Y bypass—and is about the size of a banana.

Sleeve gastrectomy patients experienced resolution rates for type 2 diabetes, high blood pressure, high cholesterol, and obstructive sleep apnea that are similar to resolution rates for other restrictive procedures such as gastric banding.

Risks and Benefits

As with any selective surgery there are risks involved. The following risks are associated with any Bariatric surgery:

  • Leakage from the intestinal tract
  • Infections
  • Bleeding
  • Blood clots in legs/lungs
  • Nausea and Vomiting
  • Gastric Bypass
  • Nutritional and Vitamin Deficiencies
  • Kinks or twists in the intestine
  • Dumping syndrome
  • Adjustable Gastric Band
  • Weight loss failure 8-10%
  • Band slippage <1-2%
  • Band erosion <0.5%
  • Balloon leaks, Port malfunction


  • Research has show that reversal of obesity- related co-morbidities has been achieved subsequent to Bariatric surgeries.
  • Studies found that gastric banding:
  • Resolved type 2 diabetes in 47.8 percent of patients and often resolved the disease within days of surgery
  • Resolved high blood pressure in 38.4% of patients
  • Improved high cholesterol in 78.3% of patients

Studies found that gastric bypass:

  • Resolved type 2 diabetes in 83.8% of patients and often resolved the disease within days of surgery
  • Resolved high blood pressure in 75.4% of patients
  • Improved high cholesterol in 95% of patients
  • Studies shows that sleeve gastrectomy patients experienced resolution rates for type 2 diabetes, high blood pressure, high cholesterol, and obstructive sleep apnea that are similar to resolution rates for other restrictive procedures such as gastric banding.
  • Bariatric patients also experienced improved physical functioning and appearance; and improved social and economic opportunities. In addition there has been a reduced relative risk of mortality as well as an improved quality of life.

Recommendations After Surgery

Weight loss after the procedure will depend on several factors including:

  • The type of surgery performed
  • Patient’s age and weight prior to surgery
  • Overall health of patient
  • Motivation of patient and support from family members, friends, and healthcare providers
  • Follow up care, ability and commitment to exercise, and maintain dietary guidelines
  • Follow up care services include consultations with Surgeon/nutritionist/nurse, support groups and bariatric rehabilitation

  • Driving is allowed once not taking pain medications.
  • Consider exercising at least 5 times per week once you are cleared by your surgeon
  • Your healthcare team will advise you when to return to work and when you are able to resume normal activities.

 Diet Plan after Weight Loss Surgery:

  • Sleeve Gastrectomy patients needs to follow each phase of diet for two consecutive weeks
  • Gastric Band and Gastric Bypass patients need to follow each phase of diet for one week
  • Phase/Week 1: Thin Liquids ex; clear liquids
  • Phase/Week 2: Soft, Moist, Mushy Food ex; yogurt, cottage cheese
  • Phase/Week 3: Soft Food ex; chicken salad, eggs, shrimp, flaky fish

Phase/Week 4+: Regular Food

  • Sip small amounts of liquids, after surgery the stomach is tiny and cannot hold large amount of liquid
  • Avoid drinking 30 minutes before and 30 minutes after a meal
