Background and aims: To evaluate the efficacy of endoscopic ultrasound for diagnosis chronic pancreatitis by Rosemont classification.
Patients and methods: A cross – sectional study was conducted on patients undergoing endoscopy ultrasound to diagnose chronic pancreatitis.
Results: Study on a total of 57 patients indicated for endoscopic ultrasound. We have some following results: The lesions of chronic pancreatitis on endoscopic ultrasound: The hyperechoic foci without shadowing and stranding is 82.5% and hyperechoic foci with shadowing is 70.2%, cyst and pseudocyst are about 15.8%. Main pancreatic duct dilation is 71.9%, hyperechoic main pancreatic duct wall is 70.2%, main pancreatic duct stone is about 45.6%. Rosemont classification in diagnosis of chronic pancreatitis: Consistent with chronic pancreatitis by 1 major A feature (+) ≥ 3 minor features is 69.4% and 2 major A features is 30,6%. Suggestive of chronic pancreatitis by over 5 minor features is 100%. EUS is more accurate than CT in detecting early chronic pancreatitis.
Conclusions:Endoscopic ultrasound is a highly effective method of diagnosing chronic pancreatitis.
