Core Tip

Core tip: Actually, there are no clear recommendations for follow-up of patients with chronic pancreatitis and solid pancreatic mass lesions. We followed-up patients with chronic pancreatitis and solid pancreatic mass lesions and we assessed the final outcome and identified an optimal surveillance interval. We found that almost one-third of patients with chronic pancreatitis had pseudotumoral chronic pancreatitis, and 22.2% had unresectable pancreatic adenocarcinoma less than 2 mo after the initial diagnosis. Endoscopic ultrasound fine needle aspiration can miss malignancy in nearly 25% of patients with pseudotumoral chronic pancreatitis.
