Weight-Loss Surgery at Corona Regional Medical Center
If you’ve tried diets, exercise, medications and other methods without success, weight-loss surgery may be an option.
Request an AppointmentCorona Regional Medical Center offers a variety of weight-loss surgery options for patients, including gastric bypass, sleeve gastrectomy and gastric band removal. Additionally, we set ourselves apart by offering robotic-assisted surgical options and education prior to surgery with specially trained nurses.
Roux-en-Y Gastric Bypass
Surgeons place a staple line across the top portion of your stomach to create a very small stomach pouch. They then connect the new stomach pouch to the small intestine. This reduces the amount of food eaten and decreases absorption of the food that is consumed.
Vertical Sleeve Gastrectomy
About 60 to 80 percent of the stomach is permanently removed. The part of the stomach that remains connects to your esophagus and small intestine, forming the shape of a sleeve. This procedure offers an alternative to those who are at a high risk for gastric bypass surgery.
Adjustable Gastric Band Removal
Lap band surgery (laparoscopic gastric banding) can help you lose weight by creating a small pouch in the stomach that limits how much food you can eat. If the band doesn’t work as expected, or if it slips or erodes, surgery may be needed to remove it.
