Patients Awareness - Endoscopic Ultra Sonography (EUS)

EUS (Endoscopic Ultrasound)

  • Minimal invasive procedure in which endoscopy is combined with ultrasound to obtain images of the chest and digestive tract, adjacent organs and lymph nodes.
  • EUS is performed on an OPD basis and is well-tolerated by most people

Procedure:

  • EUS is performed with the patient sedated.
  • The endoscope is passed through the mouth and advanced through the esophagus to the suspicious area.
  • From various positions between the esophagus and duodenum, organs within and outside the gastrointestinal tract can be imaged to see if they are abnormal, and they can be biopsied by a process called fine needle aspiration (FNA) by inserting a needle through the stomach lining into the target. EUS with FNA lasts about for an hour.
  • Organs such as the liver, pancreas, and adrenal glands are easily biopsied, as are any abnormal lymph nodes.
  • Gastrointestinal wall can be imaged if it is abnormally thick, suggesting inflammation or malignancy.
  • EUS can be used to locate gall stones which may have migrated into the common bile duct.

Advantages of EUS:

  • EUS is used to find the cause of symptoms such as abdominal or chest pain, to determine the extent of diseases in digestive tract and lungs.
  • EUS may help in the detection of:
  • Cancer of the esophagus, lung, stomach, pancreas, colon, ampullary and rectal cancers.
  • Lymphoma
  • Barrett's esophagus
  • Neuro endocrine tumors
  • Pancreatitis and pancreatic cysts
  • Bile duct stones
  • Rectal fistulas and faecal incontinence
  • To assess the depth of the tumour.
  • Determine the extent (stage) of cancer.
  • Determine if cancer has spread (metastasized) to your lymph nodes or other organs
  • Guide drainage of pseudocysts and other abnormal collections of fluid in the abdomen.
  • Evaluate abnormal findings from imaging tests, such as cysts of the pancreas.
  • Permit precise targeting for delivering medication directly into the pancreas, liver and other organs

Risks:

  • Bleeding in case of FNA.
  • Pancreatitis, if fine-needle aspiration of the pancreas is done. Infection
  • Perforation of intestinal wall.
  • larming signs after EUS-
  • Fever
  • Vomiting
  • Difficulty swallowing
  • Severe or persistent abdominal pain
  • Chest pain
  • Shortness of breath
  • Black or very dark-coloured stool

Preparation before EUS:

  • Nil by mouth before EUS.
  • If EUS is being done in rectal area, bowel clearance by laxatives or enema.
  • Stop certain medications, such as blood thinners as it may increase risk of bleeding in case of FNA. If you have chronic conditions, such as diabetes or high blood pressure, your doctor will give you specific instructions regarding your medications.
  • Arrange for someone to drive you home after the procedure.
