Laparoscopy is the technical term for minimally invasive surgical procedures, requiring only the tiniest of incisions. Michigan Bariatric Institute specializes in providing our patients with three different bariatric surgery options. They are:
Laparoscopic Gastric Bypass
Considered the "gold standard" of weight loss surgery, laparoscopic gastric bypass is the most often-prescribed weight-loss surgical procedure in the U.S. It involves surgically creating, from the existing stomach, an approximately 1 ounce stomach pouch located at the uppermost portion of the stomach and then connecting this newly fashioned stomach pouch to a shorter length of small intestine. This is the only procedure that bypasses both the remaining portion of stomach and a significant length of small intestine, effectively decreasing caloric intake and decreasing hormone creation, which stimulates appetite. With a laparoscopic gastric bypass, patients don't eat as much, don't retain as many calories, and don't get as hungry as they did before.
Patients on average lose 70 percent of their excess body weight and cures diabetes in 84 percent of patients, even some of those on insulin injections. Those who are not fully cured of diabetes at the very least experience improvements in their conditions. Sleep apnea is eliminated in nearly 87 percent of patients. High blood pressure and reflux disease is eliminated in 75 percent of patients. Joint disease is eliminated in 40 percent of patients, and the list of health improvements continues on and on. Gastric bypass patients, on average, lose 70 percent of their excess body weight. Dr. Zeni is extensively experienced in this particular surgery and will gladly answer any questions that you may have.
Laparoscopic Sleeve Gastrectomy
Laparoscopic sleeve gastrectomy has become an increasingly common operation offered to obese patients. It is a restrictive procedure that decreases the stomach volume by 80 percent. The remainder of the intestine remains the same and food digests the same as it normally would. Therefore, food is normally absorbed and there is no risk of vitamin or mineral malabsorption. The small size of the new stomach limits caloric intake and decreases some hormones that stimulate appetite. Therefore, patients feel less hungry.
However, there is increasing evidence the surgery does much more than decrease a patient's stomach to limit the amount of room for food. The University of Cincinnati has been looking at how after sleeve gastrctomy, there is a change in bile acids and bacterial groups that are in the stomach naturally. The change in acids and bacteria influences weight loss and type II diabetes. Also, the surgery has shown to decrease the hormone ghrelin, which is a hormone that acts in the brain to increase hunger. The sleeve gastrectomy may be a restrictive procedure but it is becoming more clear that its effects have a profound impact on metabolism that help people lose weight and reduce weight-related medical conditions.
Laparoscopic Adjustable Gastric Banding
The laparoscopic adjustable gastric banding or "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.
The band does not cause any anatomical changes and no risk of nutrient malabsorption. The band has several other advantages. First, it is adjustable. The band allows for an individualized degree of food restriction, pregnancy is supported by allowing for increased nutritional needs and adjustments are easily performed in the surgeon's office. A second advantage is its reversibility. The band is removable at any time and anatomy is restored to its original form. The bad has fewer side effects and fewer risks.
However, in comparing the results to other bariatric surgeries, the lap band results in less weight loss and less resolution of medical ailments which often accompany obesity, such as fatigue, depression, high blood pressure and diabetes.
Non-surgical band adjustments at regular intervals and close follow-up are needed to optimize weight loss, and for the motivated patient, laparoscopic adjustable gastric banding can be associated with effective weight loss.
Laparoscopic Duodenal Switch
Laparoscopic Duodenal Switch is the most complex bariatric surgery. First, a laparoscopic sleeve gastrectomy is performed to reduce intake. Next, 80 percent of the small intestine is bypassed and connected to the duodenal to limit the number of calories absorbed by the body. The laparoscopic duodenal switch involves both restriction and malabsorption and leads to the best weight loss of all bariatric surgeries. Patient compliance is crucial for this surgery.
