I read some info online (but I am a total novice about medical so this is really out of my league). Sounds to me like they use staples in some cases as they are "more secure". But I also had stitches (Tycron stitches and Tycron sutures – which I assume are the same thing? and Vicryl and Monocryl stitches in different areas. I did read there is some controversy about using staples. But, thank you very much for your reply. (And I hope I am all wrong about feeling something like a staple pricking me inside. Maybe it is just stitches – but it is only one tiny area and never gets better.).
