Laparoscopic Gastric Bypass (Roux-en-Y)

Also referred to as the Roux-en-Y (roo-en-wy) gastric bypass, this highly effective surgery involves creating a small pouch from the top portion of the stomach. This newly created pouch is then connected directly to the small intestine. Following the procedure, consumed food enters the small pouch and proceeds directly into the small intestine, successfully bypassing the majority of the stomach and the first section of the small intestine. This restrictive and malabsorptive technique is considered the gold standard for robust weight loss.

Gastric Sleeve Surgery (Sleeve Gastrectomy)

The Gastric Sleeve, or sleeve gastrectomy, is a highly popular and successful bariatric procedure. During the surgery, Dr. Siller removes a large portion of the patient's stomach, leaving behind only a narrow, tube-like "sleeve." By significantly reducing the stomach's capacity, this procedure restricts calorie intake and fundamentally reduces hunger signals, allowing patients to feel full sooner and sustain their weight loss goals long-term.

Adjustable Gastric Band (Lap-Band)

For patients seeking a non-permanent alteration to their anatomy, the Gastric Band provides an excellent solution. This is a minimally invasive, quick, reversible, and completely adjustable weight loss procedure. An adjustable silicone band is placed around the upper part of the stomach to decrease its size and reduce total food intake, facilitating steady and controlled weight loss.

Mini Gastric Bypass (MGB)

The Mini Gastric Bypass is a shorter, simpler, and reversible laparoscopic weight loss surgery. During this highly effective procedure, Dr. Siller bypasses 2 to 7 feet of the patient's intestines. It offers excellent weight loss results with a slightly shorter operating time and potentially fewer complications than the traditional bypass, making it an excellent choice for eligible candidates.
