Services
Sleeve Gastrectomy
Sleeve gastrectomy reduces stomach size to a tube-like pouch, limiting food intake and hunger hormone production. Ideal for patients seeking significant weight loss with lower complication risks compared to bypass procedures. Dr. Feng uses robotic-assisted techniques for enhanced precision and faster recovery.
Gastric Bypass
Gastric bypass creates a small stomach pouch and reroutes the intestine to reduce calorie absorption. Effective for severe obesity and metabolic conditions like diabetes. Dr. Feng employs laparoscopic methods to minimize scarring and postoperative discomfort.
Adjustable Gastric Band
The LAP-BAND system restricts stomach capacity via an adjustable silicone band. Reversible and customizable, it suits patients preferring non-malabsorptive options. Dr. Feng monitors band adjustments to optimize weight loss outcomes over time.
Duodenal Switch
Duodenal switch combines stomach reduction with intestinal rerouting to maximize calorie malabsorption. Reserved for extreme obesity cases (BMI 50+), it delivers substantial weight loss but requires strict nutritional management to prevent deficiencies.
Robotic Surgery
Robotic-assisted surgery enhances surgical precision using 3D imaging and advanced instrumentation. Dr. Feng utilizes the da Vinci Surgical System to perform complex bariatric procedures with smaller incisions, reduced pain, and quicker recovery periods compared to traditional methods.
