Once the clinical condition of the patient deteriorates and the patient is febrile, fine needle aspiration FNA can be used to differentiate between sterile and infected collections.

Drain runs parallel to pancreatic bed. At surgery, the collection contained much necrotic debris, which was not depicted on CT.

The CT severity index CTSI combines the Balthazar grade points with the extent of pancreatic necrosis points on a point severity scale. The radiologic image is used to confirm or exclude the clinical diagnosis, establish the cause, evaluate the severity, detect complications and provide a guide for therapy 9.

Most collections that persist after 4 weeks are walled-of-necrosis. Introduction The acute pancreatitis AP keeps on being one of the gastrointestinal pathologies with more incidence and that can unchain a significative mortality.
