Do you often suffer in silence, taking over-the-counter and prescription medications to dull the effects of gastroesophageal reflux disease (GERD) without treating the condition itself? This revolutionary procedure, is new to the Springfield area medical community performed by Springfield Clinic General Surgeon James Fullerton, MD, who can help you find relief without invasive surgery.

  • A quick review of the gastro-esophageal anatomy – previously new technologies for treating GERD focused on the LES. EGS believes that the GEV is the more important and powerful component of the anti-reflux barrier. There has been lots of misunderstanding of this anatomy, and a widespread understanding of the GEJ is just now coming to fruition. The group at Virginia Mason Medical Center in Seattle (where EGS ’ founder, Stefan Kramer, worked with other thought leaders Drs Hill, Lowe, Kozarek, etc) were invited to rewrite the chapter on the GEJ in Grays Anatomy, because before 1997, Grays Anatomy did not even mention the GE flap valve! This shows the drawing of the anatomy that has been published in Gray ’ s Anatomy since 1997 based on Dr. Hill and Kraemer ’ s research. Interestingly, the lower esophageal sphincter (LES) is a bit of a misnomer, since it does not have a band of smooth muscle cells typical of most ‘ sphincters ’ . Structurally it is not significantly different from the rest of the esophagus, and the increase in pressure at this site (LES high pressure zone) is likely an artifact of the presence of the diaphragm on the outside of the esophagus at this level. In cadavers, where there is no muscle tone, no reflux of the stomach contents is seen. This implies that something other than the LES is responsible for stopping reflux. The increase in pressure at the LES is also small, probably not enough to effectively cease all reflux. Instead, EGS is focusing on the GE flap valve. Surgery (i.e. Nissen, Hill, Toupet) has shown that restoring the angle of His and recreating the flap valve effectively stops reflux. As you know, the angle at which the esophagus enters the stomach creates this flap valve that rests against the lesser curve of the stomach to close off the stomach from the esophagus. It was demonstrated by Dr. Hill ’ s work that when the stomach is distended or the GEJ stretches out, it causes the angle of His to flatten and opens the esophagus to the stomach contents. The positive intragastric pressure causes reflux of the stomach contents if the GEV is not present. As a result of overeating, ingestion of carbonated beverages and eating large quantities of food rapidly, the stomach is stretched, the angle of His is lost and the GEV is open. The EsophyX product was designed to correct the anatomical defect which in the past was corrected by performing a Fundoplication (typically a Nissen or Toupet is performed) either open or laparoscopically.
  • Define Endoluminal Therapy - all surgical procedures that involve instrument penetration into the lumen of the gut in order to perform a surgical procedure.
  • Objective: Demonstrate the thought process of a patient goes through when contemplating treatment options for their pathology Script: “ When deciding upon a treatment for a specific pathology, patients will often make a selection based upon the effectiveness vs. the invasiveness of the procedure. In other words, “ Does it work, and how much does it hurt? ” What are your thoughts about this equation?

  • 4. GERD Facts
    • 10% of adults suffer daily heartburn
    • Incidence increases after 40 yo
    • 50% of patients require lifelong tx
    • Most GERD gets worse with time
    • Increased esophageal cancer risk with untreated severe GERD
  • 5. Acid Reflux Symptoms
    • Heartburn
    • Dysphagia or odynophagia
    • Hoarseness
    • Cough, asthma
    • Regurgitation
    • Pneumonia
    • Abdominal pain
  • 6. Anatomy
    • Lower Esophageal Sphincter (LES)
    • Relaxes to allow swallowing
    Angle of HIS Fundus
    • Gastroesophageal Flap Valve (GEV)
    • 180° flap valve, maintains closure against lesser curve of stomach
    • Is closed by pressure in the stomach to prevent reflux
