The Massachusetts General Hospital Gastroesophageal Surgery (GES) Program brings together surgical experts to provide optimal treatment and outcomes for conditions including gastroesophageal reflux disease, hiatal hernias, achalasia, and gastric and esophageal cancers.

Our surgeons work collaboratively with physicians in the Swallowing and Heartburn Center within the Digestive Healthcare Center and the Tucker Gosnell Center for Gastrointestinal Cancers within the Mass General Cancer Center to provide comprehensive, personalized treatment for patients.

Leaders in Novel and Minimally Invasive Procedures

Surgeons in Mass General’s GES program pioneered the introduction of several minimally invasive techniques for the treatment of upper GI conditions. They are leaders in developing and introducing new procedures:

  • Magnetic sphincter augmentation (LINX®) for the treatment of GERD
  • Per oral endoscopic myotomy (POEM) technique for the treatment of achalasia
  • Laparoscopic procedures for anti-reflux surgery, fundoplication, Heller myotomy, hiatal hernia repair, and cancers of the stomach and gastroesophageal junction
  • Minimally invasive esophagectomy for esophageal cancer and other esophageal pathology
  • Transoral, endoluminal treatment of Zenker’s diverticulum, avoiding a traditional neck incision

Mass General is one of the few hospitals in the United States with expertise in the evaluation, counseling and management of patients with hereditary diffuse gastric cancer (HDGC) syndrome due to the CDH1 mutation, including the successful performance of a prophylactic total gastrectomy in 15 patients.

Expertise in Complex Open Surgeries

Our surgeons perform high volumes of surgical procedures each year. For complex and reoperative surgery, our multidisciplinary team collaborates to provide expert care to patients. Procedures performed include:

  • Subtotal (partial) gastrectomy
  • Total gastrectomy, including prophylactic total gastrectomy for HDGC syndrome
  • Complex repair of hiatal and paraesophageal hernias
