GERD Gastroesophageal Reflux Disease Prof. Faisal Ghani Siddiqui FCPS; PGDip-bioethics; MCPS-HPE faisal@lumhs.edu.pk www.lumhs.edu.pk/faculties/surgery/gsurgery/faculty
PREAMBLE • What is GERD? • LES? • What causes GERD? • How does GERD present? • What are its complications?
What is GERD? Condition characterized by heartburn andregurgitation due to the loss of the HPZ
GERD • Common; Accounts for majority of esophageal pathologies • Chronic disease; needs life-long medical treatment • Surgery is effective; provides long-term relief
PATHOPHY-SIOLOGY of gastroesophageal Reflux Disease
LES HPZ located at the EG junction No distinct anatomical sphincter 3-4 cms long 10-25 mmHg Relaxes during swallowing / belching
3 Resting LES pressure Overall length of the sphincter Intra-abdominal length of the sphincter
3 Resting LES pressure Overall length of the sphincter Intra-abdominal length of the sphincter
3 Resting LES pressure Overall length of the sphincter Intra-abdominal length of the sphincter
Permanently Defective LES • Mean resting pressure < 6mm • Overall length < 2cm • Intra-abdominal length < 1 cm
of Gastroesophageal Reflux Disease SYMPTOMS
Heartburn • Regurgitation • Dysphagia • Chest pain
of Gastroesophageal Reflux Disease COMPLICATIONS
Squamousepitheliumreplaced by columnarepithelium Norman Barrett 1950
Barrett’s Esophagus Endoscopically identified columnar mucosa, which on biopsy shows intestinal mucosa with goblet cells
MANAGE-MENT of Gastroesophageal Reflux Disease
CONSERVATIVE TREATMENT • Antacids • Alginic acid • Metoclopromide / domperidone • Proton pump inhibitors • Change in life style
Change in Life-style • Elevate head of the bed • Avoid tight fitting clothes • Eat small, frequent meals • Avoid eating before bedtime • Dietary changes
PPI’s suppress acidity & relieve symptoms but do not control reflux Control of refluxbetter than control of symptoms!
INVESTIGATE IF SYMPTOMS… • Persist or progress • Recur
INVESTIGATIONS • Endoscopy • 24-hour pH monitoring • Manometry
WHEN TO OPERATE? • Persistent or progressive disease • Young patients with documented reflux • Stricture • Barrett’s esophagitis
GOAL OF SURGERY to restore normal structure/pressure of the LES while preserving patient’s ability to swallow, and to belch
PRINCIPLES • Restore pressure (>12 mmHg) • Restore length (at least 3 cm) • Place adequate length in abdomen (1.5 – 2 cm)
ANTIREFLUX PROCEDURES • Nissen fundoplication • Toupet partial fundoplication • Belsey Mark IV partial fundoplication
COMPLICATIONS • Temporary dysphagia • Inability to vomit • Increased flatulence
