Gastric Outlet Stenosis

Gastric Outlet Stenosis (GOS) is a condition that affects the stomach, making it difficult for food to pass through to the small intestine. In this article, we will provide simple explanations for various aspects of GOS, including its types, causes, symptoms, diagnostic tests, treatments, drugs, and surgical options.

Types of Gastric Outlet Stenosis:

  1. Pyloric Stenosis: This is a common type of GOS where the pylorus, the muscle at the end of the stomach, becomes too tight, obstructing food flow.
  2. Peptic Ulcer Disease: Repeated ulcers can lead to scarring and narrowing of the outlet.
  3. Cancer: Stomach or pancreatic cancer can block the outlet.
  4. Gastric Polyps: Growths in the stomach lining can cause narrowing.

Causes of Gastric Outlet Stenosis:

  1. Peptic Ulcers: Ulcers can scar and narrow the outlet over time.
  2. Inflammation: Chronic inflammation in the stomach lining can lead to stenosis.
  3. Tumors: Both benign and malignant tumors can block the outlet.
  4. Surgical Complications: Some surgeries can inadvertently cause stenosis.
  5. Crohn’s Disease: An inflammatory bowel disease that can affect the stomach.
  6. Scarring: Injuries or trauma can result in scarring and narrowing.
  7. Medications: Long-term use of certain drugs, like NSAIDs, can contribute.
  8. Infections: Viral or bacterial infections can lead to inflammation.
  9. Congenital Conditions: Rarely, GOS can be present from birth.
  10. Radiation Therapy: Past radiation treatment near the stomach can cause stenosis.
  11. Autoimmune Disorders: Conditions like eosinophilic gastroenteritis can be a cause.
  12. Chronic Pancreatitis: Inflammation of the pancreas can affect the outlet.
  13. Helicobacter pylori: A bacterial infection linked to ulcers and stenosis.
  14. Gastric Polyps: Abnormal growths in the stomach lining.
  15. Foreign Bodies: Ingested objects can cause blockage.
  16. Celiac Disease: An autoimmune disorder that affects digestion.
  17. Zollinger-Ellison Syndrome: A rare condition leading to excess stomach acid.
  18. Vascular Disorders: Blood vessel problems can affect stomach blood flow.
  19. Gastroenteritis: Severe inflammation of the stomach lining.
  20. Neuromuscular Disorders: Nerve or muscle problems can disrupt digestion.

  10. Capsule Endoscopy: A small camera pill that passes through the digestive tract.
  11. 24-Hour pH Monitoring: Monitors acid levels in the esophagus.
  12. Sigmoidoscopy: Examines the lower part of the stomach.
  13. Radionuclide Imaging: Uses a radioactive substance to visualize the stomach.
  14. Helicobacter pylori Test: Checks for this bacterial infection.
  15. Abdominal X-ray: Basic imaging to look for abnormalities.
  16. Upper GI Series: X-rays taken while drinking barium contrast.
  17. Serum Amylase and Lipase: Tests for pancreatic function.
  18. Fecal Occult Blood Test: Checks for hidden blood in stool.
  19. Small Bowel Follow-Through: Imaging of the small intestine.
  20. Anorectal Manometry: Assesses the rectal and anal muscles.

Treatments for Gastric Outlet Stenosis:

  1. Dietary Changes: Soft or liquid diet to ease digestion.
  2. Medications: Acid reducers, anti-inflammatories, or antibiotics.
  3. Endoscopic Dilation: Widening the narrowing with a balloon or stent.
  4. Stent Placement: A mesh tube to keep the outlet open.
