Pancreatic Pseudocyst – causes, symptoms, diagnosis, treatment

Table of Contents

The word pseudo means ‘not true. A pseudocyst is considered a cyst but it consists of different types of tissues than a true cyst. In the pancreatic pseudocyst, the pancreas gets inflamed.  The digestive enzymes leaked from the inflamed pancreas. It became a disorder. The fluids collect. It is called pancreatic pseudocyst.

History of Pancreatic Pseudocyst

Cannon et al were the first ones to describe pancreatic pseudocyst long following about two and half periods ago. Controlling blister differences in life remains an ancient complication. On starting of the 20th period, a scientist differentiates between accurate necrotic cyst and pseudocyst. He described that a pancreatic cyst is a stripe over tissue and a cyst is a border at boundary makeup by connective tissue and shaping cells.

To a greater extent period later on the prime explanation, in the Atlanta classification of 1933, some clear consent and guidance were developed. Organization of the Atlanta comprises of 4 well-defined disorder organization: subacute substance collection which arises at the specific period about subacute substance and it still no longer contain cystic boundary;

subacute pancreatitis pseudocyst develops as a residue the subacute substance and physical injury or its boundary comprises the shaping cells moreover extremely material; constant pancreatic pseudocyst, it develops like a residue the constant pancreases and is similarly bound with the boundary; pancreas ulcer, these acts as an internal belly store the secretion right away present close with the liver, beyond each huge space about virulence.

Intense juicy collection, pancreatic pseudocyst, and the pancreatic ulcer are differentiated against each other over ancient times, abnormalities in boundary and imaging studies about the wall.


Due to acute and chronic pancreatitis, Pseudocyst is formed. Mostly it is formed due to the constant pancreases then the intense pancreases. Shortage about documents but most of the cases and reports show that the pseudocyst is formed due to the pancreatic injury. Complications of the intense or constant pancreases give rise to pancreatic pseudocysts.

In the acute pancreases, the appearance of the pancreatic pseudocysts is described from 6% to 18.5%. In chronic pancreatitis, the appearance of the pancreas cyst was described from 20% to 40%. Usually in a patient pancreatic pseudocyst is due to alcoholic chronic pancreatitis. Its chances are from 70% to 78%.


In 1991, the classification of pancreatic pseudocyst was narrated by D Egidio and Schein. And this classification was established on the prime analysis of intense or constant pancreatitis, and anatomy of pancreas tube, more existence of the transmission mid-way the blister and the pancreas tube.

More they narrated the 3 well-defined kinds about the pancreatic pseudocyst. The first type is acute post necrotic pseudocyst. It takes place behind the chapter on acute pancreatitis. And it is attached to the anatomy of a normal duct. It has less communication along the pancreases tube. Kind two is as well as post necrotic pseudocyst.

It takes place after a chapter of acute followed by chronic pancreatitis. Type three is retention pseudocysts. It is due to chronic pancreatitis and it is uniformly attached with an abnormality of the duct and the communication of the pseudocyst.

Nealon and Walser had given another classification. This classification is completely built on the anatomy of the pancreatic duct. Type one includes a normal duct that has no transmission with the cyst. Type two is also a normal duct but it has transmission along with the blister. Kind three is the typical tube with the abnormality and has no transmission along with the blister.

Kind four is also a typical tube but has an abnormality and has transmission along with the blister. Kind five is a normal duct but is completely blocked. Type six is chronic pancreatitis but it does not have duct and cyst transmission. Type seven is also chronic pancreatitis but it has transmission between duct and cyst.


The causes of pseudocyst formation involve pancreatitis. Pancreatitis is an expansion of the liver and is the utmost trivial root of the pancreas cyst. If the liver is aroused conversely undergoes any injury, then it starts to leak enzymes. And these enzymes injured the tissue of the pancreas. Pancreatitis is mostly caused by alcohol consumption which then leads to the formation of pancreatic pseudocyst. It is mostly due to chronic pancreatitis.

Pancreatic pseudocyst can also be caused by trauma, such as abdominal blow, but it is a less common cause of pseudocyst. Other less common causes are poisonous from medicines and complications in surgical treatment.


The symptoms of pseudocyst are different in different people. Some of its diagnosis symptoms are bloating and abdominal pain. The pseudocyst symptoms may also include

  1.     Vomiting
  2.     Loss of appetite
  3.     Fever
  4.     Diarrhea
  5.     Weight loss
  6.     Skin and eyes yellowing
  7.     In the abdominal cavity, the buildup of fluid.
  8.     Nausea



Ultrasound (USG) is the most important diagnostic equipment among different imaging devices. In most cases, it is a useful pointer of diagnosis. Its application is

  1.     Abdominal ultrasound
  2.     Study of doppler effect
  3.     Scanning with duplex
  4.     Ultrasound endoscopy

The pancreas false cyst looks like a silent structure. Generally, it is round or oval in shape. It is surrounded by a smooth wall attached with a point that is away from origin under ultrasound inspection. These are most prominent and in circle shape, and these are attached with soft boundaries. A pseudocyst is very complex in the prior stage of growth.

It has varying degrees of internal echoes. Sometimes due to excessive bowel gas, the early direction is missed. Interpretation on USG becomes difficult if dangerous waste and discharge are present in the sac and inflammation begins. Doppler technique and scanning technique must be all-time done in cyst bruises.

It sure one that bruise is not a big.75% to 90% is reactivity cost for ultrasound in the analysis about the pancreas pseudocyst. CT has a sensitivity rate from 90% to 100%. So, the US is lower to CT.US has many restrictions with contrast to computed tomography, within the earlier detection about false cyst:


Treatment of the pancreatic pseudocysts consists of two steps. one is medical treatment and other is the surgical treatment. Basic requirements are internal venous fluid, pain killer medication. Usually, the small pseudocyst gets better and may go away on their own. If the small pseudocyst is not causing any serious symptoms, a doctor use to monitor it with CT scan periodically.

If this small pseudocyst persists and gets larger instead of getting better, then it is treated by drainage. In drainage process and endoscope is passed in through the mouth to the stomach and small intestine. This endoscope has an endoscopic ultrasound as well as a small needle for draining the cyst. In some cases, the drainage of cysts through the skin is compulsory.

For the drainage of the cyst through the skin, a tube is passed through the skin. If pseudocyst is not monitored and treated, it may rupture or become infected which then causes severe pain, blood loss, and abdominal infection. On conservative treatment, the cyst of large size and long persistent cyst does not react. They have more complications during the disease. Usually in this group morbidity and mortality is present. The patients of this condition require surgical treatment and are handled surgically.


Surgery for pseudocyst

Pseudocyst requires surgical treatment. In the surgery process of the pseudocyst, the surgeon usually creates a connection of pseudocyst with nearby located digestive organs. This connection allows the pseudocyst to drain through this organ. This organ is usually stomach or small intestine depending on the location of the pseudocyst in the pancreas.

In some cases, the surgery is done through incision in abdomen which is termed as laparoscopically the surgical drainage, lap and open method is usually adopted. Both have a great effect on the solace. Because a technique is used called laparoscopy.

In the case of emergency relief, external drainage is the best option. Otherwise, EUS or surgical drainage is the preferred method.

Risk Factor

Pancreatitis is a factor which increases the risk of pseudocyst. This pancreatitis is caused by the use of alcohol in an excess amount which ultimately leads to a pancreatic pseudocyst. Another risk factor of pancreatic pseudocyst is an injury in the abdomen.


Pancreatic pseudocyst requires close examination for its early makes out otherwise it will produce complications that will be more devastating for a person of this disease.


infection is due to sudden and afterward treatment and analysis. Earlier sore false cyst is cured by traditional way but large number of people require involvement. Conventionally, surgery is a modern way of treatment while endoscope sonography has acquired popularity. The outer drain is compulsory within some chosen condition like a while there was proof about the tumor and a person is not stable for the surgical and endoscopic drainage.


Gush is largely affected route about false cyst or is destructive. The rate of disease and death is increase but this come into sight beyond any signal was general because of wearing away huge tube within proximity about the false cyst. If it doesn’t recognize right away then the lives of persons are in extreme danger. Surgical treatment works as an important character within approaching reason of the bloodshed or within obstruction about blood tube. Beyond knowing where is bloodshed region is, operational treatment is dangerous or testing.

The obstacle of the gastric

False cysts present in the upper part of the pancreas were generally were a reason for outlet obstruction. If this is the characteristics about the obstacle of the gastric appear then this surely required surgical treatment or decomposition and drain about the sac. Sometimes endoscopy treatment is needed.


Pancreatic pseudocyst is usually caused by pancreatitis so, if you want to avoid the pancreatic pseudocyst you must avoid pancreatitis. The pancreatitis is mainly caused by excess use of alcohol and by gallstones.

If pancreatitis is being caused by gallstones, the patient required the gallbladder to be removed if pancreatitis is being caused by excess use of alcohol, then you can avoid it by leaving the alcohol drinking. By avoiding the pancreatitis, a patient can avoid the risk of pancreatic pseudocyst.

Hypertriglyceridemia is also a reason for pancreatitis. If you have this problem, then you have a higher level of triglyceride. A higher level of triglyceride more than 1000 mg/dl increases a person’s chances for pancreatitis.



Pancreatic pseudocyst is the most common form of cystic lesions of the pancreas, the description for this type of lesion is 75%-80%. Abdominal pain, nausea and vomiting is the most general symptoms of pancreatic pseudocyst. If a person has these symptoms, it does not mean he has this disease, sometimes these symptoms can be the reason for some other disease.

For early imaging, CT scan of abdominal is great choice. A pseudocyst is differentiated from other cystic lesions of the pancreas, EUS play important role in this. Supportive care is needed in early dealing. Continuing symptoms and the development of complications require treatment. For the drainage of the pancreatic pseudocyst, endoscopic drainage and less noisy therapeutic treatment is preferred than open surgical techniques.

Although they are most successful they cannot always perform. If we made a decision of treatment, we remember fifty percent pancreatic pseudocyst has no need some surgical treatment and is deal by victory and see the point of view. The success rates of laparoscopic and endoscopic drainage are more. Transcutaneous drainage are sometime worst. Treatment center must have experience of these techniques. The choice of treatment also depends on experience of the treatment center.
