  Ninh T. Nguyen, MD
  Surgeon

Dr. Nguyen, a specialist in surgeries of the gastrointestinal tract, is highly experienced in minimally invasive techniques, including laparoscopic adjustable gastric banding and Roux-en-Y bariatric surgeries, staging of esophageal cancer, esophagectomy, fundoplication, resection of gastric stromal tumors and photodynamic therapy. A board-certified gastrointestinal surgeon, Nguyen and colleagues conducted the first study to show that diagnostic and surgical procedures performed through keyhole incisions rather than large open wounds result in fewer complications, less post-operative pain, shorter hospital stays and faster recovery compared to traditional open gastric bypass surgery with newer laparoscopic techniques.
