Endoscopic ultrasound is one of the most sensitive methods to detect changes in the pancreatic parenchyma. There have been no publish studies that describe changes observed proximal to the pancreatic tumor, which could be related to the origin of it, unlike the post-tumor changes by pancreatic duct obstruction, which are described in the literature. Objective: To describe the observed changes in the pancreas by EUS before and after the tumor. Methodology: We retrospectively evaluated videos of 36 patients who underwent upper endoscopy eco diagnosed with pancreatic cancer, they were received between January and December 2009, there were excluded patients with lesions in the uncinate process and tail of the pancreas, because they did not show change pre and post tumor. The images were interpreted according to established patterns. The data were emptied in tables and analyzed by percentages. Results: 18 patients had cancer of the head of the pancreas, 12 in the neck and 6 in the body. Evidenced changes proximal to the tumor, a majority showed areolar pancreatopathy 58% (21): 4 mild, 10 moderate and 7 severe; followed by pancreatic steatosis 33% (12): 2 homogeneous,10 heterogeneous, and 9% (3) normal pancreas. The observed post-tumor changes were obstructive tumoral pancreatitis 94% and 6% had a normal pancreas. Conclusion: It is possible that the presence of chronic areolar pancreatopathy could be related to the development of pancreatic cancer. We confirmed the presence of malignant obstructive pancreatitis distal to lesion in most patients.
