Pancreatic juice – secreted into the duodenum, first part of small intestine; contains a variety of enzymes: Pancreatic amylase – starch digestion. Trypsin – major enzyme in pancreatic juice; protein digestion. Pancreatic Lipase – fat digestion.

The intestinal juice contains much mucus and some digestive enzymes, which assist with digestion. The pancreas lies behind the stomach and is the most important source of the enzymes that digest all three of the major types of food (see Digestion, below).

Your pancreas creates natural juices called pancreatic enzymes to break down foods. These juices travel through your pancreas via ducts. They empty into the upper part of your small intestine called the duodenum. Each day, your pancreas makes about 8 ounces of digestive juice filled with enzymes.

Gastrointestinal Functions Pancreatic juice consists of alkaline (chiefly bicarbonate) fluid and enzymes; 200–800 ml is produced each day. The enzymes, such as trypsin, lipase, and amylase, are essential for the digestion of most of the protein, fat, and carbohydrate in the meal.

The Biological Function of Gastric Juice. Gastric juice is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. Its main function is to inactivate swallowed microorganisms, thereby inhibiting infectious agents from reaching the intestine.

CT should be used in patients who are classified as having severe pancreatitis or are at risk of developing severe pancreatitis; ideally after 72 h, to best assess the full extent of the disease[13].

CT showed a diagnostic accuracy of 83.3%, with sensitivity and specificity of 81.4% and 43% respectively. MRI showed superior diagnostic accuracy compared to CT (89,1%). However, EUS demonstrated the best diagnostic value in PC (accuracy of 92,7%).

From the small intestine, endoscopic ultrasound can also be used to look at the pancreas, gallbladder, or bile ducts. For this test, an endoscope is fitted with a small ultrasound probe on its tip.

MRI is more reliable in diagnosing chronic pancreatitis than CT or ultrasonography[40]. MRI will identify parenchymal atrophy, duct dilation, and pancreatic ductal and parenchymal changes after hormonal stimulation[40,41]. Chronic pancreatitis damages the acinar cells, main pancreatic duct, and side branches.
