The treatment of pancreatic pseudocysts is as follows: 1. observation treatment: most cysts can be absorbed by the body, so early patients generally do not need special treatment and can be observed for six weeks or six months; 2. surgical treatment: if the volume of the cyst does not decrease through observation, or even increases or combined with infection and bleeding, such patients generally need surgical treatment, mainly laparoscopic or gastroscopic internal drainage surgery; patients who show bleeding are generally treated with external drainage surgery; patients with huge cysts can be treated with laparoscopic sequential external and internal drainage surgery of transgastric cysts with good efficacy.
