Pancreatic encapsulated necrosis can be cured and the healing time is related to the complexity of the necrosis. The treatment can be done through large diameter metal stent drainage, repeated debridement to gradually remove the encapsulated necrotic debris, which can be gradually absorbed after it turns into clear liquid, as long as the necrotic material is completely removed, the cystic cavity will gradually heal. As long as the necrotic material is completely removed, the cystic cavity will gradually heal. Depending on the complexity of the type of necrosis, the difficulty of debridement varies, and the number of times of debridement will be increased in more complex types, resulting in longer hospitalization of the patient.
