Gallbladder Polyps

What are Gallbladder Polyps?

Gallbladder polyps are small, abnormal growths or lesions that can develop on the inner lining of the gallbladder. These growths can be benign (non-cancerous) or malignant (cancerous). Most gallbladder polyps are benign and do not cause any symptoms, but some larger polyps or those with certain characteristics may need further evaluation and monitoring.


Impact of Gallbladder Polyps on Anatomy and Health

In many cases, the presence of gallbladder polyps may not have any noticeable impact on a person's anatomy or health. Small, benign polyps typically do not cause symptoms or lead to any complications. However, larger polyps or those with a potential for malignancy can lead to various issues:

  • Cholecystitis: Large polyps can obstruct the bile flow or irritate the gallbladder wall, potentially leading to inflammation known as cholecystitis.
  • Obstruction of Bile Ducts: Larger polyps may block the bile ducts, causing bile buildup and leading to pain, jaundice (yellowing of the skin and eyes), and other complications.
  • Risk of Cancer: Most gallbladder polyps are benign, but some can become cancerous over time. Regular monitoring and evaluation are essential to detect any malignant transformation early.
  • Gallstone Formation: In some cases, gallbladder polyps can contribute to the formation of gallstones or increase the risk of developing them.
  • Rare Complications: Rarely, a large polyp may lead to gallbladder torsion or twisting, which can cause severe pain and potentially require emergency surgery.


Causes and Risk Factors for Gallbladder Polyps

The exact cause of gallbladder polyps is not always clear, but certain risk factors can increase the likelihood of their development. Some of the factors associated with an increased risk of gallbladder polyps include:

  • Age: The risk of gallbladder polyps increases with age, with older individuals being more susceptible.
  • Gender: Women have a higher risk of developing gallbladder polyps than men.
  • Obesity: Obesity, including polyps, is a known risk factor for gallbladder disease.
  • Gallstones: Individuals with gallstones are at an increased risk of developing gallbladder polyps.
  • Family History: Your risk may be higher if you have a family history of gallbladder polyps or gallbladder cancer.
  • Certain Medical Conditions: Certain conditions, such as primary sclerosing cholangitis and chronic gallbladder inflammation, may increase the risk of developing polyps.


Many gallbladder polyps are asymptomatic and are often discovered incidentally during abdominal imaging for unrelated reasons. If you have concerns about gallbladder polyps or related symptoms, it's crucial to consult a doctor for appropriate evaluation and management.


Symptoms of Gallbladder Polyps

In many cases, gallbladder polyps do not cause noticeable symptoms, especially if they are small and benign. As a result, individuals with gallbladder polyps often remain unaware of their presence. These polyps are usually discovered incidentally during imaging tests or examinations for other health issues.


However, larger polyps or those associated with complications may lead to symptoms such as:

  • Abdominal Pain: Pain or discomfort in the upper right side of the abdomen, particularly after eating fatty or greasy foods.
  • Nausea and Vomiting: Some individuals may experience nausea and vomiting, especially if the polyps obstruct the bile ducts.
  • Jaundice: Yellowing of the skin and eyes due to the obstruction of the bile ducts by large polyps.
  • Fever and Chills: In cases where a polyp causes inflammation or infection of the gallbladder (cholecystitis), fever and chills may occur.


These symptoms are not exclusive to gallbladder polyps and can indicate various other gallbladder or gastrointestinal conditions. If you experience persistent or severe symptoms, seeking medical attention for proper evaluation and diagnosis is crucial.


Types of Gallbladder Polyps

Gallbladder polyps can be classified based on their appearance and characteristics into several types:

  • Cholesterol Polyps: These are the most common type of gallbladder polyps and are typically small, benign growths composed mainly of cholesterol deposits.
  • Adenomas: Gallbladder adenomas are less common but have a higher potential for becoming cancerous compared to other types. They are glandular growths that can vary in size.
  • Inflammatory Polyps: These polyps are formed due to chronic gallbladder inflammation and are typically small and benign.
  • Neoplastic Polyps: Neoplastic polyps encompass adenomas and other polyps with the potential for malignant transformation.


Diagnosis of Gallbladder Polyps

Gallbladder polyps are often incidentally detected during abdominal imaging studies for other reasons. If a polyp is suspected, further evaluation is usually recommended. The diagnostic process may include the following:

  • Ultrasonography (US): Ultrasound is a commonly used imaging technique to visualise the gallbladder and detect polyps. It can also help determine the size and number of polyps present.
  • Computed Tomography (CT) Scan: CT scans can provide detailed cross-sectional images of the gallbladder, aiding in evaluating polyp characteristics and their relation to surrounding structures.
  • Magnetic Resonance Imaging (MRI): MRI can offer additional information about the polyp's appearance and help distinguish between benign and potentially malignant polyps.
  • Endoscopic Ultrasound (EUS): EUS is a specialised technique that uses an endoscope with an ultrasound probe to obtain detailed images of the gallbladder and surrounding tissues, allowing for better characterisation of polyps.
  • Biopsy: In some cases, a biopsy of suspicious polyps may be performed to determine if they are cancerous.
  • Follow-up Monitoring: Small, asymptomatic polyps may be monitored over time with regular imaging to observe any changes in size or appearance.


Treatment of Gallbladder Polyps

The treatment of gallbladder polyps depends on their size, characteristics, and associated symptoms. In many cases, small, benign polyps that do not cause symptoms may not require treatment but should be monitored periodically. However, larger polyps, those with suspicious features, or those causing symptoms may necessitate further evaluation and intervention. Treatment options for gallbladder polyps include

  • Observation and Monitoring: Small, asymptomatic polyps that are less than 1 centimetre in size and have a typical appearance may be monitored through regular imaging tests. If they remain stable over time, treatment may not be necessary.
  • Cholecystectomy: A cholecystectomy is a surgical procedure to remove the gallbladder. It is typically recommended for larger polyps (greater than 1 centimetre) or those with suspicious features that may indicate a higher risk of malignancy. Cholecystectomy is the definitive treatment and eliminates the risk of polyp-related complications.
  • Endoscopic Removal: In some cases, polyps can be removed endoscopically during a procedure known as endoscopic mucosal resection (EMR). This is typically reserved for small polyps confined to the gallbladder mucosa and does not invade deeper layers.
  • Medications: There is no specific medication to treat gallbladder polyps directly. However, medications may be prescribed to manage these conditions if polyps are associated with gallstones or inflammation.


What if Gallbladder Polyps are Untreated? 

If left untreated, gallbladder polyps may have the potential to cause several complications:


Consult a doctor if you have been diagnosed with gallbladder polyps or are experiencing any symptoms. They can provide personalised advice and recommend the most appropriate treatment plan based on your condition and risk factors. Early detection and timely management can prevent potential complications and ensure better outcomes.
