<s>[INST] my sister just got out of the hospital dealing with pancreaitis on the 5 of july. they have told her that a cyst has formed and has to wait until the wall is thick enough to drain. they are wanting to do surgery aug 2. my qeustion is can she return to work until the surgery...they have said her pancreas is completely healed.... [/INST] This is not pancreatic cyst but a pseudo pancreatic cyst  and your doctor wants you to wait so as to let the wall of cyst get thick cause it can be easily drained then. This is done to avoid complication as thin wall cyst may burst in abdomen while trying to drain it . Once the wall becomes thick it can be easily drained by making a passage either in stomach or in intestine. So relax and follow your doctor's advice.......tc care </s>
