The duodenal switch (DS) combines malabsorptive elements to achieve weight loss. The DS procedure includes a partial gastrectomy, which reduces the stomach along the greater curvature, effectively restricting its capacity while maintaining its normal functionality. This means that part of the stomach is permanently removed. Unlike the unmodified BPD and gastric bypass Roux-en-Y (RNY), which use a gastric “pouch” and bypass the pyloric valve, the DS procedure keeps the pyloric valve intact. This eliminates the possibility of dumping syndrome, marginal ulcers, stoma closures and blockages, all of which can occur after other gastric bypass procedures.
The malabsorptive component of duodenal switch surgery rearranges the small intestine to separate the flow of food from the flow of bile and pancreatic juices. This inhibits the absorption of calories and some nutrients. Further down the digestive tract, these divided intestinal paths are rejoined and food and digestive juices then begin to mix. Limited fat absorption occurs in the “common tract,” as food continues on toward the large intestine.
As a person ages, the skin loses some of its natural elasticity and the muscles gradually weaken. The aging process often has a pronounced impact on the abdominal region, resulting in a flabby, sagging midsection. For some, the loss of definition in the stomach area is a source of self-consciousness, as they begin to appear older and less fit than they feel. In such cases, a tummy tuck can have a rejuvenating effect on the entire body.
The overall shape of one's body and the areas where pockets of fat tend to accumulate are largely determined by genetics. For some people, the bothersome flab that gathers in the abdominal region may not be reflective of their true level of activity and fitness. Even a person in his or her 20s, 30s, or 40s may be genetically predisposed to stubborn abdominal roundness; fortunately, plastic surgery can address this.
Traditional tummy tucks are the most commonly performed type of tummy tuck surgery. They involve the creation of a hip-to-hip incision, as well as incisions around the belly button. Because they address the patient's entire abdominal area, they often involve moving the belly button to ensure natural looking results. Traditional tummy tucks are commonly combined with abdominal liposuction.
Mini tummy tucks (also called partial abdominoplasties) are intended for patients who are within 10 percent of their ideal body weight and are content with making alterations only to the part of the abdomen that is below the navel. Mini tummy tucks require only a single small incision. They usually do not involve repositioning the navel. Partial abdominoplasties result in less dramatic changes to the appearance of the abdomen.
