Overview

Isolated agenesis of the gallbladder is a rare congenital condition in which a person is born without a gallbladder, and this occurs without other major birth defects or organ abnormalities. The gallbladder is a small, pear-shaped organ located beneath the liver that normally stores bile, a fluid produced by the liver to help digest fats. When the gallbladder is absent from birth, bile flows directly from the liver into the small intestine through the bile ducts instead of being stored and concentrated. Many people with this condition have no symptoms at all and may never know they are missing their gallbladder unless it is discovered incidentally during imaging for another reason. However, some individuals develop symptoms that can mimic gallbladder disease, including upper right abdominal pain, nausea, bloating, fatty food intolerance, and indigestion. These symptoms can be confusing because doctors may initially suspect gallstones or other gallbladder problems. This condition is important to recognize, especially before any planned surgery. In some cases, surgeons have attempted laparoscopic cholecystectomy (gallbladder removal surgery) only to discover that no gallbladder exists. Diagnosis is typically made through imaging studies such as ultrasound, CT scan, or MRI. In most cases, no treatment is needed. For those who experience digestive symptoms, dietary changes and medications to manage bile flow or digestion may be helpful. The overall prognosis is excellent, and the condition does not typically shorten life expectancy.

Key symptoms:

No symptoms at all in many casesUpper right abdominal painNauseaBloating after mealsDifficulty digesting fatty foodsIndigestionVomitingJaundice in rare cases if bile ducts are affectedAbdominal discomfort that mimics gallstone attacks
