EUS Guided Drainage of Post Pancreatitis Pancreatic Fluid Collection

"The technical success rates, clinical success rates, and potential complications of the different endoscopic ultrasound-guided techniques for the best drainage of pancreatic fluid collections (PFCs) as regard type, caliber, and number of plastic stents and the ideal timing for stent removal will be assessed.~Also compare early vs. late intervention for complete endoscopic necrosectomy of walled off pancreatic necrosis (WOPN ) as regard to technical success rates, clinical success rates, potential complications, and the number of sessions needed will be done.~In order to evaluate total resolution or a reduction in cyst diameters with clinically significant improvement in symptoms, patients will be monitored for one month and six months following the insertion of the stent."
