Endoscopic Ultrasound, EUS

Feature Summary

pancreatic pseudocyst/abscess

Pancreatic pseudocysts and pancreatic abscess develop commonly in the setting of pancreatitis as a result of focal damage and/or necrosis to the pancreas. These lesions will not only compress or obstruct the duodenum, bile duct, or stomach but lead to sepsis or death.



Most infection of pseudocyst is severe and results in a sepsis syndrome. This often requires a surgical debridement or drainage for resolution. Linear EUS provides a new method for dynamic imaging, aspirating, and draining pseudocysts or abscess. Nowadays, external drainage using EUS guidance is the most common approach.



To resolve symptom and treat infection related to pancreatic pseudocyst or abscess.



Preparation for transgastric drainage is 12 hours fasting before the procedure. Mild sedatives can be used to relieve discomfort. Transgastric stenting of pseudocysts/abscess will be performed using EUS to determine the entry site for catheterization and then introduce the guidewire into the lesion cavity. X ray can be used to confirm the location. Therefore, more than one stents will be inserted into the cavity through guidewire.
