BOOK AN APPOINTMENT

Pancreatic cysts are fluid-filled sacs in the pancreas, a vital organ behind the stomach. The pancreas plays a crucial role in digestion and blood sugar regulation, producing enzymes that break down food and hormones such as insulin.

 

Pancreatic cysts can vary in size and type, ranging from benign cysts requiring minimal to no treatment to malignant cysts needing more aggressive management.

Types of Pancreatic Cysts

Pancreatic cysts in Singapore are classified into several types based on their pathology and the potential for malignancy.

Pseudocysts

Pseudocysts are the most common type of pancreatic cysts, typically forming as a result of pancreatitis. These cysts are non-cancerous and are filled with fluid and debris from pancreatic enzymes. Pseudocysts do not contain an epithelial lining, distinguishing them from true cysts.

Serous Cystadenomas

Serous cystadenomas are benign cysts filled with a thin, watery fluid. They are usually not cancerous and tend to grow slowly. These cysts can occur anywhere in the pancreas and are more common in women than men.

Intraductal Papillary Mucinous Neoplasms (IPMNs)

IPMNs are a type of cyst that forms in the pancreatic ducts. They can either be main duct IPMNs, which have a higher risk of becoming cancerous, or branch duct IPMNs, which have a lower risk. These cysts produce mucin and can lead to blockage of the pancreatic duct.

 

IPMN treatment in Singapore depends on factors like cyst type, size, duct involvement, and patient health among other factors, with treatment options ranging from surveillance to surgery.

Mucinous Cystadenomas

Mucinous cystadenomas are precancerous cysts that can potentially become cancerous if not appropriately managed. They are filled with thick, mucinous fluid and are more likely to occur in women.

Solid Pseudopapillary Neoplasms

Solid pseudopapillary neoplasms are rare pancreatic tumours that can become cancerous. They typically affect younger women and have a better prognosis than other pancreatic cancers when surgically removed early.

Causes and Risk Factors of Pancreatic Cysts

  • Pancreatitis
    Pancreatitis, or pancreas inflammation, is a significant risk factor for developing pancreatic cysts, particularly pseudocysts. Both acute and chronic forms of pancreatitis can lead to cyst formation.
  • Genetic Predisposition
    Certain genetic mutations and hereditary conditions can increase the risk of developing pancreatic cysts, such as mutations in the PRSS1, SPINK1, or CFTR genes associated with pancreatitis.
  • Age and Gender
    The incidence of pancreatic cysts tends to increase with age, with most cases diagnosed in people over the age of 60. Some types of cysts are also more prevalent in women.
  • Smoking
    Smoking is a known risk factor for pancreatitis and pancreatic cancer. This highlights the importance of smoking cessation in reducing the risk of pancreatic disorders.
  • Alcohol Consumption Both long-standing type 2 diabetes and new-onset diabetes may be associated with pancreatic cancer.
  • Obesity
    Obesity is associated with an increased risk of pancreatitis and may indirectly influence the risk of developing pancreatic cysts through its impact on pancreatic health.
  • History of Abdominal Injury
    A history of abdominal trauma can lead to the development of pseudocysts as a result of pancreatic damage.

Pancreatic Cyst Symptoms

Pancreatic cysts often remain asymptomatic, especially in their early stages. However, when symptoms do occur, they can vary depending on the size, location, and type of the cyst.

Some common symptoms of pancreatic cysts to watch out for include abdominal discomfort, fullness, pain in the upper right abdomen, nausea, and jaundice.

  • Abdominal Pain
    Pain in the abdomen, particularly in the upper middle or upper left side, can occur if a cyst grows large enough to press on other structures in the abdomen.
  • Nausea and Vomiting
    Large cysts or cysts that obstruct the stomach or duodenum may cause nausea and vomiting, often exacerbated by eating.
  • Jaundice
    If a cyst compresses the common bile duct, obstructing bile flow, the skin and eyes may be yellowed.
  • Weight Loss
    Unintended weight loss can occur if a cyst interferes with digestion or appetite or as a general response to the body’s stress from the cyst.
  • Changes in Stool
    A cyst obstructing the digestive tract can lead to changes in stool, such as steatorrhea, where stools become oily or greasy due to fat malabsorption.
  • Palpable Mass
    Upon physical examination, a large cyst may be felt as a mass in the abdomen.
  • Diabetes
    Cysts that affect the endocrine function of the pancreas may contribute to the development of diabetes by impairing insulin production.

Pancreatic Cyst Diagnosis

Imaging Studies

  • Ultrasound: Often used as an initial assessment by pancreatic cysts specialists, ultrasound can help detect the presence of pancreatic cysts.

  • Computed Tomography (CT) Scan: A CT scan provides detailed cross-sectional images of the pancreas, helping to identify the cyst's overall structure and size, as well as its location.

  • Magnetic Resonance Imaging (MRI): MRI offers detailed images of the pancreas and surrounding structures. This is useful for identifying types of cysts and their potential for malignancy.

  • Endoscopic Ultrasound (EUS): EUS involves using an endoscope equipped with an ultrasound device inserted through the mouth and into the stomach to obtain close-up images of the pancreas.

Cyst Fluid Analysis

Fluid obtained from a cyst during EUS is analysed for cytology and tumor markers (e.g., CEA, amylase) to differentiate between benign and malignant cysts and identify specific types.

Blood Tests

While blood tests alone cannot diagnose pancreatic cysts, they can provide information on the pancreas’s overall health and detect markers associated with inflammation or malignancy. For instance, the CA 19-9 blood test may be performed to assess for malignant potential, though high levels can also indicate other conditions.

When is Surgery Required for Pancreatic Cysts in Singapore?

The management of pancreatic cysts varies based on their characteristics and potential risk.

 

For small, low-risk cysts without worrying features, a strategy of active surveillance is often recommended. This involves routine imaging follow-ups in Singapore to monitor the cyst for any changes over time.

 

Surgery may be recommended when a pancreatic cyst presents features that suggest a higher risk of malignancy or causes significant symptoms. Key indications for surgical intervention include:

 

  • Size greater than 3cm
  • Presence of mural nodules (growths within the cyst wall)
  • Dilation of the main pancreatic duct
  • High-grade dysplasia on cytology (abnormal cells indicating a high risk of cancer)
  • Symptoms such as jaundice, persistent pain, or recurrent pancreatitis

Pancreatic Cyst Treatment Options

The treatment of pancreatic cysts in Singapore is highly individualised, based on the type of cyst, its size, location, and whether it shows signs of cancer.

  • Observation and Monitoring

    For small, asymptomatic cysts with a low risk of malignancy, a conservative approach involving regular monitoring with MRI or CT scans is often recommended. This strategy helps to track any changes in the cyst’s size or appearance over time.

  • Endoscopic Treatment

    Certain types of cysts can be treated endoscopically. This may involve endoscopic ultrasound-guided drainage, where a needle is used to drain the cyst fluid, or the insertion of a stent to allow cysts to drain into the digestive tract.

  • Surgical Removal

    Surgery in Singapore is considered for symptomatic pancreatic cysts, growing or having a high risk of turning cancerous. The type of surgery depends on the cyst’s location and the condition of the surrounding pancreatic tissue.
  • Distal Pancreatectomy: This procedure involves removing the body and tail of the pancreas and is typically performed for cysts located in these areas. The spleen may also be removed if necessary.

  • Pancreaticoduodenectomy (Whipple Procedure): For cysts located in the head of the pancreas, a Whipple procedure may be performed. This involves removing the head of the pancreas, the first part of the small intestine, the gallbladder, and part of the bile duct, with reconnection of the remaining organs to allow digestion.
  • Enucleation: For smaller cysts that are well-defined and not deeply integrated into the pancreatic tissue, enucleation allows for the removal of the cyst while preserving the majority of the pancreatic tissue.

Complications Associated with Pancreatic Cysts

While many pancreatic cysts are benign and may not cause significant issues, some can lead to complications, such as:

Infection

Cysts can become infected, leading to pancreatitis or abscess formation. This requires prompt medical treatment, often including antibiotics and possibly surgical drainage.

Rupture

A cyst rupture is a serious condition that can lead to leakage of cyst contents into the abdominal cavity, potentially causing peritonitis (inflammation of the abdominal lining) and internal bleeding.

Pancreatitis

Cysts, especially those obstructing the pancreatic duct, can contribute to pancreatitis. This condition can be acute or chronic and may necessitate hospitalisation and intensive treatment.

Biliary Obstruction

Large cysts located near the bile duct can compress it, leading to obstructive jaundice. This may require surgical or endoscopic intervention to relieve the obstruction.

Frequently Asked Questions About Pancreatic Cysts in Singapore

Are pancreatic cysts cancerous?

Pancreatic cysts are often non-cancerous (benign), but some types can have malignant potential, meaning they could turn into cancer over time. Accurate diagnosis and surveillance from a hepatobiliary specialist is crucial to determine the nature of a cyst.

Pancreas surgery in Singapore for a pancreatic cyst is typically recommended by a specialist when there are features that suggest a higher risk of malignancy, such as a size greater than 3cm, the presence of mural nodules, main pancreatic duct dilation, high-grade dysplasia on cytology, or if the cyst is causing significant symptoms like jaundice, pain, or pancreatitis.

Once a pancreatic cyst is surgically removed, it generally does not grow back in the same location. However, in some individuals, new cysts can potentially develop in other parts of the pancreas. Regular follow-up with a surgeon or a specialist may be advised depending on the individual’s condition and the type of cyst removed.
