Is it common to develop a bruise on your abdomen following a tlh with ovary removal?

Yes: Yes in the first 2 weeks.

Not Uncommon: You could have a bruise from the injection of Heparin (to prevent blood clots) or from insertion or manipulation of the trocars used during the surgery. Alternatively, it could represent a little bit of oozing at the skin closure from the trocar sites. Most of the time this will go away in a week or so by itself. If it persists or continues to grow, see your doctor.
