Cystogastrostomy is an endoscopic outpatient surgery that is performed to remove a pancreatic pseudocyst.

Some facts about Cystogastrostomy:

  • A pancreatic pseudocyst may develop after acute or chronic pancreatitis.
  • The pancreas produces enzymes that help digest food, hormones that regulate blood sugar, and bicarbonates that help neutralize stomach acid.
  • The most common cystic lesion of the pancreas is Pancreatic pseudocyst.
  • Although most pancreatic pseudocysts in children resolve spontaneously with conservative management, some require sort of therapeutic intervention which varies depending on the nature and position of cyst, presence of complications and surgeon's experience.
  • Lesions that are symptomatic, larger than 6 cm in diameter, or persist for more than 6 weeks may require a therapeutic interventions.
  • Percutaneous drainage, endoscopic drainage and surgical drainage by laparotomy or by laparoscopy can be done or these cases.
  • Abdominal pain, satiety, nausea, vomiting and upper gastrointestinal bleeding are some of the symptoms of a pancreatic pseudocyst.
  • The development of life-threatening complications including infection, gastric outlet obstruction, obstructive jaundice, fistula formation, spontaneous rupture and massive hemorrhage can be avoided by a Cystogastrostomy.
  • Pancreatic abscess and pancreatic duct leak can be a result of Cystogastrostom.
  • The stents used during the surgery can become blocked, leading to infection of the pseudocyst.

Preparation for Cystogastrostomy:

  • Your condition will be accessed to ensure that you are healthy enough for a complex operation.
  • Some additional medical tests and optimization of some of your health conditions will be done before proceeding to surgery.
  • Any history of bleeding disorders or are taking any blood-thinning (anticoagulant) medicines, aspirin, or other medicines that affect blood clotting should be informed to your healthcare provider as you may need to stop taking these medicines before your surgery.
  • Take your medicine with a small sip of water to avoid drinking too much liquid if you do have to take any medications.
  • You should not eat or drink anything after midnight, the night before surgery. 

Procedure for Cystogastrostomy:

  • An opening between a pancreatic pseudocyst and the stomach will be created when the cyst is in a suitable position to be drained into the stomach during Cystogastrostomy.
  • Pancreatic juices can be conserved by this procedure that would otherwise be lost.
  • An incision will be made in the abdomen during surgical repair.
  • The cystogastrostomy is created and it is attached to the wall of the stomach after locating the pseudocyst.
  • It is infrequently used despite a high success rate because of the recovery period.
  • Endoscopic cystogastrostomy is a relatively less-invasive method that involves endoscopic ultrasound (EUS) guidance and fluoroscopy.
  • A large bore needle will be used to access the pseudocyst by creating a fistula between the cystic cavity and either the stomach or the duodenum.
  • Plastic stents will be be placed to facilitate drainage from the pseudocyst.
  • Laparoscopic cystogastrostomy can also be used to drain pseudocysts and can be performed by a single surgeon because of the advanced tools. 
  • The pseudocyst will be accessed using laparoscopic techniques after identifying it.
  • It is entered and aspirated, and an opening is created into the stomach for drainage once the pseudocyst cavity is located.
  • Better cosmetic appearance and decreased pain following surgery are the advantage of Laparoscopic drainage.
