Hi ladies who saw no external stitches and had nothing removed - you probably had a sub-cutaneous dissolvable suture - which is a long dissolving stitch that is done under the skin. The plastic thing is a just a dressing they keep on to keep the germies out for the first few days (after which time the wound has mostly knit together again).

This is what I had and is the most common thing at the hospital I attended. Still only 2 weeks later so I can't really comment on how it has healed, etc.
