hi. biliary colic is the symptom you experience when you have a concern in any part of your hepatopancreatico-biliary tree. when you experience a colicky pain, it is intermittent, waxing and waning in character, epigastric to right upper quadrant in location, sometimes with radiation to the back, shoulder and/or whole abdomen. it usually occurs right after a fatty meal. I suggest that if your appointment is still in a few days time, diet modification would be best. avoid high fat food as it might aggravate your condition, and the elective might be an emergency case instead. it is best if you consult with a doctor, preferably a gastroenterologist or a general surgeon, for physical examination and clinical evaluation. diagnostics, such as ultrasound and liver function tests, and management (medical and/or surgical if indications are found) will be directed accordingly. hope this helps. good day!! ~dr.kaye
