Extremely elevated liver ALT/AST levels alone grounds for ER visit?

My wife was taken to the ER last week. The pain lasted maybe 2 hours and was mainly pain and nausea. We were informed there that she has gallstones and evidence of an enlarged bile duct (perhaps from ping a stone). Her ALT/AST levels from a liver function blood test were elevated at the time, but on a second p blood test the day after were elevated even more so - on the order of 600 and 1000. We received the results from this second p just today. My wife is at home now and is not showing any symptoms. So with ALT/AST levels this high from a test last week, and not showing any other symptoms, should we take her to the ER? Or just wait to see if she has any more 'attacks'? FYI we have an appointment with a surgical group to plan the removal of her gallbladder late next week.
