Acute severe pancreatitis is a disease with a long treatment period and high treatment costs.

Acute severe pancreatitis is pathologically staged, generally divided into the organ failure phase, also known as the inflammatory response phase. Typically, this occurs within 7 days after the onset of severe pancreatitis, during which there is a massive release of inflammatory factors, causing multiple organ failures. This stage is perilous and often requires the support of multiple organ functions, such as ventilators and hemofiltration treatments.

After this inflammatory response phase, it transitions into a chronic phase of abdominal infection, which occurs approximately one week to one or two months after the onset. At this time, there is a large amount of effusion in the abdominal cavity, and some of the effusion may develop secondary infections. The main treatment at this stage involves puncture drainage of the effusion. Once an infection is detected, puncture drainage is performed on the infected site to manage the infection.

Therefore, the treatment period for severe pancreatitis primarily depends on the duration of organ function support, recovery time of organ functions, and the severity of the infection. Some organ function support may be prolonged, requiring several months, and sometimes irreversible conditions occur, such as acute renal failure transitioning into chronic renal failure.

Abdominal infections are more complex. If the infection is severe and recurrent, long-term puncture drainage or surgical removal of the infection may be necessary, often requiring several months of treatment.
