What is a Pseudocyst or Pancreatic fluid collection?

A pseudocyst or pancreatic fluid collection is a collection of fluid that may form around or within the pancreas following an episode of pancreatitis. Pseudocysts may cause abdominal pain, nausea and vomiting and they may become infected.

There are a number of options in managing pancreatic fluid collections and these may include surgery, endoscopic interventions or radiological interventions. Hence management of pancreatic fluid collections involves a multidisciplinary team including Gastroenterologists, Surgeons and Radiologists.

What is a Cyst Gastrostomy?

A commonly performed procedure in managing pancreatic fluid collections is the drainage of such collections using endoscopic ultrasound into the stomach. This is achieved using complex endoscopic techniques. In simple terms the procedure involves the placement of one of more tubes (stents) through the stomach wall and into the cyst. This allows drainage of the cyst contents into the stomach and avoids the need for an external drain.

What is a Nasocystic tube and why is it used?

Sometimes it is necessary to leave a long tube into the cyst that comes out of the nose. This is known as a nasocystic tube. This tube can be used to wash out the cyst contents and improve drainage of infected material from the cyst.

What is Necrosectomy?

In some cases where a fluid collection is infected, an endoscope can be advanced from the stomach into the cyst to allow debridement of the infected tissue and accelerate healing. This is known as endoscopic necrosectomy. Necrosectomy often needs to be undertaken over several procedures.
