The suffix is the bit that will tell you about what procedure, condition, disease or disorder you're dealing with.
Note, that even the word anatomy has this suffix. That is because at the time it was established, it relied heavily on dissection of things.
When you hear this suffix, it means they're going to cut something.
The most common examples you might run into are surgeries to repair cruciate ligament injuries: Tibial Plateau Leveling Osteotomy (TPLO) or Triple Tibial Osteotomy (TTO). Osteo meaning bone, -tomy meaning cutting; surgical cutting of a bone.
Another example would be a Triple Pelvic Osteotomy (TPO), one of the surgeries for hip dysplasia.
Laparotomy stands for a surgical procedure involving opening of the abdominal cavity and examination of the abdominal organs, laparo meaning abdominal wall. In other words, cutting the belly open, exploratory surgery of the abdomen, and so on.
