No two patients have similar gall-stones, they differ in numbers, size, shape, color, consistency, chemical composition, site etc. This do matter a lot in cases of minimal access surgery. For example stone is solitary and you have removed it then no further wasting of time to search other stones, second example if stone or stones are 1 cm and cystic duct is 3 mm then there will be no chance of stone to go into CBD, vise versa stones are 2mm then chances are they may go to CBD.
