Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the value of preoperative objective modalities such as endoscopic ultrasound elastography and magnet resonance imaging in predicting development of postoperative pancreatic fistula in patients undergoing pancreatic surgery for benign or malignant disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

One of the most generally accepted causes of postoperative pancreatic fistula (POPF) is soft texture of the pancreas. The stiffness of organs depends on histologic features such as content of fat, fibrotic tissue and micro vascular structures. Yet, pancreatic stiffness was evaluated only subjectively. Endoscopic ultrasonography (EUS) and magnetic resonance imaging (MRI) may allow objective quantification of pancreatic stiffness prior to surgery.

Endoscopic ultrasound elastography (EUE) is based on real-time Doppler technology. Image colors are derived from vibration patterns which depend on the stiffness of a specific region of the investigated organ. The retrieved images could be converted into numeric matrix using a specially designed program.

Magnetic resonance imaging (MRI) is a non-invasive method for quantitatively assessing the mechanical properties of tissues based on fat tissue content.

In this trial the investigators will assess at first the value of EUE and MRI in predicting development of postoperative pancreatic fistula and in a next step the value EUE and MRI as an objective method in prediction of pancreatic stiffness.
