Weight Loss Surgery Procedures

Surgeons at the Bariatric Center of Excellence perform more weight loss surgeries than any other hospital in the state of Maryland. Our surgeons perform three different types of procedures and they work closely with patients every step of the way to ensure long-term weight loss success.

Gastric Bypass

Laparoscopic Gastric Roux-en-Y Bypass

The laparoscopic procedure has been performed for the past 10 years and is a minimally invasive surgery with a number of benefits. During the procedure, a surgeon partitions off part of the stomach, creating a small pouch that can hold only a limited amount of food. In addition, the surgeon reroutes the small intestine to limit absorption of food and calories. 

Depending on your BMI, your previous surgery history, and some other factors, the procedure will take about two hours. An average hospital stay is about two days and the recovery period lasts three to four weeks. 

Gastric Bypass Surgery and the daVinci Robot System
The daVinci Robotic Surgical platform is one of the two gastric bypass surgeries offered at Saint Agnes Hospital. It provides a significant enhancement to the minimally invasive approach of Laparoscopic surgery, which is the second form of gastric surgery.

The robotic platform significantly increases visualization by using HD imaging, greater magnification, and 3D enhancements. These enhancements allow fewer complications, and better functional and cosmetic outcomes for patients. 

Gastric Bypass Surgery Benefits
This type of surgery is the most frequently performed weight-loss operation in the United States. Patients can expect to lose between 65 to 70 percent of their pre-surgery excess weight (actual weight minus ideal body weight) due to the combination of restricted food intake and reduced calorie absorption.

Gastric Banding

Gastric Banding surgery is the newest weight loss surgery approach and it is the only adjustable obesity surgery available in the United States. During the procedure, surgeons place an inflatable band around the stomach to limit its capacity and increase the feeling of being full. Once implanted, the band can be tightened or loosened by inflating or deflating the balloon on its inner surface, allowing for an individualized degree of restraint with more or less caloric intake. 

The initial procedure usually takes approximately one hour. Subsequent adjustments are performed in a matter of minutes in an outpatient setting. 

Gastric Banding Surgery Benefits
While less invasive than Roux-en-Y, weight loss with gastric banding surgery is also more gradual. Because it is adjustable, this procedure is an especially attractive option for younger female patients who are likely to become pregnant in the near future and will need to increase nutrition for proper fetal development.

Sleeve Gastrectomy

Laparoscopic Vertical Sleeve Gastrectomy
IIn the past 5 to 10 years, sleeve gastrectomy, also known as vertical sleeve gastrectomy, has emerged as an endorsed alternative to gastric bypass and gastric banding procedures. During the weight loss surgery procedure, the surgeon removes part of the stomach, thus restricting the amount of food that can be consumed. The advantage of the procedure is that normal continuity of the gastrointestinal tract is preserved, while the capacity of the stomach to hold food is drastically reduced by 80 to 90 percent. 

This weight loss surgery procedure can be performed laparoscopically and takes about one-and-a-half hours to perform. Surgery is followed by a hospital stay of about two days. Patients can expect to return to work in three to four weeks. 

Sleeve Gastrectomy Benefits
Post-surgery weight loss is similar to gastric bypass results. Sleeve gastrectomy allows patients to avoid some of the potential complications associated with other two procedures. It can be performed in patients who have contraindication, or do not want gastric bypass or gastric banding procedures.

Possible Risks of Weight Loss Surgery

Only about 20 percent of patients that have had weight loss surgery require follow-up operations to address complications or elect to have reconstructive or plastic surgery after their weight loss stabilizes. Some patients who aren’t able to permanently change their eating habits and lifestyle experience inadequate weight loss or regain weight.
