Living with Annular pancreas

A birth difference in which the pancreas forms a ring around part of the small intestine.

Understanding Annular pancreas

Annular pancreas is a condition present from birth in which the head of the pancreas forms a ring around part of the small intestine (the duodenum).

It is described as a form of duodenal atresia, which is a blockage or narrowing of the first part of the small intestine. It is a digestive system condition that shows up in newborns and infants. GARD lists a dominant inheritance pattern.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Pancreas ring around the small intestine (annular pancreas)
  • Narrowing of the first part of the small intestine (duodenal stenosis)
  • Blockage high in the intestines (high intestinal obstruction)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include digestive system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

InheritanceAutosomal Dominant

GARD says changes in genes (also called variants) cause this condition. It can be inherited in an autosomal dominant way, meaning one changed copy of the gene can be enough to cause it.
