Had her gallbladder removed a few weeks ago after a few days she came home but after a day she went bck cos she had pancreatitis what can help her gas?

Retained stone: Is the likely cause. She needs an ERCP and stone extraction.

Low fat and no booze: After a bout of pancreatitis, a patient should avoid fats and alcohol for at least 90 days. This would surely help. Smaller meals at first would help, as would the use of over the counter drugs which contain simethicone, e.g. Mylicon 60 and gasex. Ask you pharmacist for a recommendation, and keep in contact with your surgeon. Good luck.
