I have a question about lap chole. I had a baby 8 months ago and been having gallbladder symptoms in middle to end of pg to now. US of gallbladder good, EF=27%. Can't get into Dr. until Oct. 5th for consult but I work with Dr at times and know he will want to take it out. Is this a low enough EF to go though surgery? Symptoms are: Pain in upper middle quadrant of abd (sometimes mild sometimes severe), nausea, occasional vomiting, constipation/diarrhea, left sided chest pain (EKG normal), and fullness after eating.
