Lake Huron Medical Center offers three types of bariatric surgery; all procedures are available using laparoscopic or robotic-assisted surgery. Laparoscopy is the technical term for minimally invasive surgical procedures, requiring only very small incisions. With the addition of the da Vinci® SI Surgical System at Lake Huron Medical Center, robotic-assisted surgery now available for those undergoing bariatric procedures. Robotic-assisted surgery provides enhanced vision of the operative field and greater precision and physical dexterity than the human hand.

Our Bariatric Care offers:

  • Sleeve Gastrectomy
  • Gastric Bypass (Roux-en-Y)
  • Adjustable Gastric Banding (Lap Band™)

Sleeve Gastrectomy

Sleeve Gastrectomy is rapidly gaining popularity among patients seeking permanent weight loss. It involves the removal of approximately 75 percent of the stomach, leaving your stomach with about a 2-3-ounce capacity. Your stomach would then be structured as a narrowed tube. The normal continuity between the esophagus, stomach and small intestine is not changed, as it is in gastric bypass surgery. Therefore, food (including necessary vitamins and minerals) is absorbed normally. The small size of the new stomach limits caloric intake and decreases some of the hormones that stimulate appetite. Patients feel less hungry, which greatly helps with weight loss.

Sleeve Gastrectomy is a safe and effective option for patients that have 100 pounds or more to lose. On average, sleeve gastrectomy patients lose 60-70 percent of their excess body weight within 18 months.

Gastric Bypass (Roux-en-Y)

Gastric Bypass involves two components. In this procedure, the stomach is made into a small pouch to limit food intake then part of the intestine is bypassed to reduce calorie absorption. The newly created stomach pouch is considerably smaller and facilitates much smaller meals, meaning less calories consumed. The rerouting of the food stream does produce changes in hormones that stimulate appetite and suppress hunger.

Gastric Bypass produces significant long-term weight loss, typically between 60 and 80 percent excess weight is lost. Most patients maintain a weight loss of 50 percent of excess weight.

Adjustable Gastric Banding (Lap-Band™)

Adjustable Gastric Banding (Lap-Band™) involves placing a synthetic band around the uppermost portion of the stomach. The band is then tightened and adjusted to limit intake and curtail hunger. Key benefits of adjustable gastric banding are that there are no anatomical changes associated with its placement and no risk that essential vitamins and minerals are not properly absorbed. The band has several other advantages:

  • Adjustability. The band allows for an individualized degree of food restriction – for example, a pregnancy is supported by allowing for increased nutritional needs. Adjustments are easily performed in the surgeon's office.
  • Reversibility. The band is removable at any time and anatomy can be restored to its original form. The band has fewer side effects and fewer risks. Nationally, there is lower mortality risk and nutritional deficiencies with the lap band than with other more involved bariatric surgeries.

Lake Huron Medical Center provides non-surgical band adjustments at regular intervals and close follow up – both of which are needed to optimize weight loss. For the motivated patient, adjustable gastric banding can lead to effective weight loss. On the average, lap-band patients lose 50 percent of their excess body weight.
