Do I Need Urgent Surgery For Perforated Gallbladder (CT) If

Do I need urgent surgery for perforated gallbladder (CT) if I do not have any symptoms. Had Gall bladder attack and ended up in ER , after had fluctuating fever, back pain, headache but once emotional trauma underlining the cause of attack was removed it all passed. However I had CT scan scheduled so went for it and day later got call form GPp that Ii urgently need surgery. Is that so ?
