Gallbladder polyps are abnormal tissue growths that project from the inner lining of the gallbladder. These growths vary in type and composition. While most are non-cancerous, some can be associated with other gallbladder conditions or, in rare cases, cancer.
What are the different types of gallbladder polyps?
•
Pseudopolyps (Cholesterol polyps)
: These result from cholesterol buildup (cholesterolosis) and are benign.
•
Inflammatory polyps
: Formed due to chronic inflammation in the gallbladder, such as in cholecystitis.
•
Adenomyomatosis
: A non-cancerous overgrowth of the gallbladder lining that can form small cysts within the wall.
•
Adenomas
: Benign tumors made up of cells resembling those in the bile ducts. These carry a small (0.5%) chance of turning cancerous.
•
Malignant polyps
: These are cancerous, most commonly a type called adenocarcinoma.
Symptoms and causes of gallbladder polyp;
Gallbladder polyps often do not cause any symptoms and are typically found incidentally during imaging tests like ultrasounds. However, in some cases, polyps can block the flow of bile, leading to inflammation of the gallbladder (cholecystitis), bile ducts (cholangitis), or pancreas (pancreatitis).
Possible symptoms of such inflammation include:
•Abdominal pain
•Fever
•Nausea and vomiting
•Yellowing of the skin or eyes (jaundice)
In rare cases, these symptoms could also suggest gallbladder cancer.
What are the risk factors for gallbladder polyps?
You may be at higher risk if you have:
•Gallstones
•Cholecystitis
•Cholangitis
•Hepatitis B
•Familial Adenomatous Polyposis
•Peutz-Jeghers Syndrome
•High cholesterol
•Age over 50
Diagnosis and Monitoring
Unfortunately, it's not possible to determine whether a polyp is cancerous without surgically removing the gallbladder, as the polyps cannot be removed independently. Therefore, healthcare providers evaluate your symptoms and risk profile before deciding on surgery.
Can gallbladder polyps go away on their own?
No, gallbladder polyps do not disappear naturally. In fact, they tend to increase in size or number over time. Surgery is the only way to remove them.
If you’ve been diagnosed with a gallbladder polyp, it’s important to follow up with a gastroenterologist. Early evaluation can help manage risks and avoid complications.
