Resumen
The effect of acute pancreatitis on diabetic patients in terms of the occurrence of malignant tumors is not well understood. The main contribution of this study is to investigate the association between acute pancreatitis and gastrointestinal cancer in type 2 diabetic patients. Diabetic patients who had a history of acute pancreatitis showed a higher incidence of all gastrointestinal cancers, not only pancreatic cancer. The risk of gastrointestinal cancer in diabetic patients was increased by 1.6 to 4.5 times depending on the history of acute pancreatitis. It seems necessary to investigate the history of acute pancreatitis in diabetic patients and more actively recommend screening for gastrointestinal cancers in such patients. Results of this study suggest that proper management or prevention of acute pancreatitis might be important for diabetic patients.
