Pancreatic Pseudocyst: A Fluid Collection That Can Develop After Pancreatitis

The pancreas is a very metabolically important organ- as it produces insulin necessary for maintaining blood glucose levels in the body. When the pancreas gets injured or inflamed due to some condition, it can cause pancreatitis, which needs specialized treatment for you to get better. In some cases, due to pancreatitis, pancreatic juices leak and protective scar tissue forms over it, like a pouch. This is a pancreatic pseudocyst and it is a complication of pancreatitis. It is different from a pancreatic cyst and mostly goes away on their own. But, when they become infected, you will need treatment.

If you have had pancreatitis or are concerned about other symptoms, get in touch with our gastroenterologists at KIMS Sunshine Hospital, as we are the best multispecialty hospital in Hyderabad.

Causes of Pancreatic Pseudocyst

The main cause for a pancreatic pseudocyst to form is pancreatitis, of course. Pancreatitis initially can occur due to chronic alcoholism, gallstone formation or other insults.

Pancreatic Pseudocyst Symptoms

Small pseudocysts are mostly asymptomatic, but larger pseudocysts can cause symptoms like the following-

You will have abdominal pain after pancreatitis.
You may notice abdominal swelling.
You may not have much of an appetite.
You may feel very nauseous and vomit too.
If you have an infection, then you may notice fever, chills and a high heart rate.
Jaundice is a notable side effect too.

If you notice these symptoms, don’t delay treatment! Call our gastroenterologists at KIMS Sunshine Hospital right away!

Diagnosis of a Pancreatic Pseudocyst

Such pancreatic fluid accumulation in a pseudocyst can be diagnosed with high resolution imaging- like an MRI or CT scan. At times, a fine needle aspiration sample may also be taken, to check if it is a pseudocyst, cyst or some other mass altogether.

Endoscopic Ultrasound– An endoscope which is a long tube with a camera attached to one end is inserted down the throat and into the small intestine. A smaller tube is then sent in to image the pancreas, with an ultrasound wand. Endoscopic drainage pseudocyst procedure is a diagnostic test and treatment at once, since specialised instruments can be used to drain the pseudocyst too.
Fine needle aspiration– A sample of the fluid from the pseudocyst is taken and sent to a pathologist for further analysis.

Treatment For Pancreatic Pseudocyst

Apart from medications and fluids to help with dehydration, you should mostly get better without the need for any major medical intervention.

For a complicated or high risk pseudocyst, doctors recommend endoscopic drainage. Tis is minimally invasive and you will heal faster. As mentioned above, this is both a diagnostic and treatment measure.

At times however, surgery may be necessary. A cystogastrostomy is done where a conduit is made from the pseudocyst to some other organ like the pancreatic duct, small intestine or stomach- based on the location of the pseudocyst- and the end result is it draining into any one of these organs. Once the fluid has drained, the protective capsule goes away on its own.

Conclusion

A pancreatic pseudocyst is an unfortunate side effect of a severe bout of pancreatitis. Many people get better without needing any treatment but for others, an endoscopic drainage may be a good option. You will heal in about 2 days and won’t have a lot of pain by the end of the week. You can begin taking fluids or soft foods within the first two days itself. You will need to watch for any infection or pain that comes back, during or after recovery.

Frequently Asked Questions

What is a pancreatic pseudocyst?

A pancreatic pseudocyst is a fluid-filled sac that forms near the pancreas, usually after pancreatitis or injury. It contains digestive enzymes, tissue debris, and inflammatory fluid. Unlike true cysts, it lacks an epithelial lining. Pseudocysts can vary in size and may resolve on their own or require medical management.

What are the symptoms of a pancreatic pseudocyst?

Symptoms include persistent abdominal pain, nausea, vomiting, and a feeling of fullness. Larger pseudocysts can cause early satiety, weight loss, or a palpable abdominal mass. In some cases, complications such as infection or rupture lead to fever, severe pain, and worsening clinical symptoms.

How is a pancreatic pseudocyst diagnosed?

Diagnosis is made using imaging studies such as ultrasound, CT scan, or MRI, which help identify the size, location, and contents of the cyst. Endoscopic ultrasound may be used for detailed evaluation and to guide treatment decisions, especially when intervention such as drainage is being considered.

When is drainage required for a pseudocyst?

Drainage is required when the pseudocyst causes persistent symptoms, becomes infected, increases in size, or leads to complications such as obstruction or rupture. Procedures may include endoscopic, percutaneous, or surgical drainage, depending on the cyst’s characteristics and the patient’s clinical condition.

When should someone seek medical attention?

Medical attention is necessary if there is severe or persistent abdominal pain, vomiting, fever, or signs of infection. Sudden worsening of symptoms, including intense pain or abdominal swelling, may indicate complications such as rupture or bleeding, which require immediate evaluation and treatment.
