Pancreatic Cysts

Pancreatic cysts are fluid-filled sacs that can form in the pancreas, an organ located behind the stomach that plays a vital role in digestion and blood sugar regulation. While many pancreatic cysts are benign and asymptomatic, some can lead to complications.

Types of Pancreatic Cysts

• Pseudocysts: Often arise from inflammation of the pancreas (pancreatitis) and usually contain fluid, debris, and pancreatic enzymes.
• Serous cystadenomas: Generally benign and filled with a thin, watery fluid.
• Mucinous cystadenomas: These can be benign or precancerous and contain thick, sticky fluid.
• Intraductal papillary mucinous neoplasms (IPMNs): These can be benign or malignant and arise in the ducts of the pancreas.

Symptoms

Pancreatic cysts may not cause symptoms, especially if they are small. However, larger cysts or those that lead to complications may present the following symptoms:

• Abdominal pain or discomfort
• Nausea and vomiting
• Loss of appetite
• Weight loss
• Jaundice (yellowing of the skin and eyes, if the cyst obstructs the bile duct)

Causes

• Chronic pancreatitis: Inflammation of the pancreas due to long-term alcohol use, gallstones, or other factors.
• Genetic factors: Certain hereditary conditions can increase the risk of developing cysts.
• Pancreatic tumors: Some cysts may be associated with tumors, whether benign or malignant.

Treatment

• Monitoring: Small, asymptomatic cysts may just be monitored with regular imaging.
• Medications: If inflammation is present, medications such as pain relievers or anti-inflammatory drugs may be prescribed.
• Surgery: If the cyst is large, symptomatic, or suspected to be cancerous, surgical removal may be necessary.
