ABSTRACT

Purpose. Show diseases of the pancreas and their diagnosis using ultrasonography and other imaging methods such as computed tomography: show the possible clinical and pathological correlations.
Introduction. Pancreatic diseases are multiple and varied; they are usually accompanied by pain in the mesogastrium, may be consecutive to disorders such as gallstones and alcoholism or be associated with cirrhosis, or the result of traumatic injuries and inflammatory processes and constitute the basis for tumoral disorders, with different ultrasound findings as the initial diagnostic method and subsequent characterization by computed tomography. Percutaneous biopsy or draining accumulations by means of catheterization helps to evaluate the findings and establish possible correlations. Images allow us to detect manifestations ranging from inflammatory processes with increased pancreatic volume, fluid accumulations due to abscesses, and simple and complex cysts to cystic tumoral lesions such as cystadenomas or solid lesions such as insulinomas and adenocarcinomas, among others.
Material and methods. We reviewed 261 files of patients interned at Hospital San José Tec de Monterrey, with diagnosis of pancreatic disease, and evaluated the primary clinical parameters, laboratory results, results obtained with different imaging methods, and histopathology studies to document the diagnosis of tumoral disorder and compile statistics on the most common diseases at the hospital.
Results. Inflammatory conditions (pancreatitis) and varying degrees of stratification were identified, as well as pseudocysts and abscesses, in addition to detecting tumors which include ductal adenocarcinomas and serous and mucinous cystadenomas, as well as cystadenocarcinomas and other lesions with cystic components, diagnosed by means of ultrasound and in correlation with computed tomography.
Remarks. Pancreatic diseases can be detected using ultrasound for the initial assessment, but require, in addition, a full evaluation to establish a more precise diagnosis and determine the appropriate treatment. Key words: pancreas, pancreatic disease, ultrasound and tomography in pancreatic disease, pancreatitis, pancreatic tumors.
