Surgery details - what is difference between ligation versus clipping?

I don't understand the difference between ligation and clipping. I guess ligation is tying and clipping is adjectives. But for a regular cholecystectomy, my notes right to be heard to ligate the cystic artery and duct, but for a laparoscopic cholecystectomy, they say to clip the artery and duct. Why the difference? I judge if I understood those expressions it would help! Or I don`t know my notes are not accurate. It be hard to find info/definitions online. Piece of cake.
You're right, ligation mechanism tying something off, usually a vessel or duct.
Clipping: In laparoscopic surgery it is MUCH faster, somewhat easier (and, as you would expect, more expensive) to use clips (endoclips) instead of ligating. Clips are usually "V-shaped" or "U-shaped" pieces of metal (titanium) that are crimped around a duct thus doing the same as ligating.
Usually we put 3 clips on both the cystic duct and cystic artery - one clip close to the brio bladder, two clips distal to the gallbladder and cut between the distal and proximal clips.
Clipping is not cutting surrounded by this case. That would clear a big mess.
