@Legin I didn't mean this was a case of excessive and egregious malpractice, just that once in a while, in the rush of a clinic, looking at a stitch abscess, which is generally a pretty minor thing, if he took a swab of material he would likely have left it for the nurse to send off. That's what usually happens. And I am in no doubt that that's what the attending nurse would have done. But he himself may have neglected to make a note of it in the notes and he may well have forgotten about it. However, he will be reminded when the lab report comes back! What you have to remember is that these chaps are human and cannot remember absolutely everything they do in the course of a day. Do you remember everything single thing you did a week last Friday?
I want to know what material was used for my internal stitches but it is not recorded!
Well of course it should have been recorded!
But I can tell you it was either
Vicryl, Dexon, Polysorb or Surgicryl - all of which are made from
polyglycolic acid just by different companies. Polyglycolic acid is actually derived from fruit sugars and reckoned to be very compatible with human tissue (and in veterinary surgery for that matter!).
Sutures are graded on a strange system:
2 For repair of tendons or other high tension structures in large orthopedic
1 hip surgery or deep layers in back surgery.
0 For closing of the fascia layer in abdominal surgery, the joint capsule in knee
2/0 repair of bowel in general surgery or general skin closure
4/0, 3-0 skin closure in fine skin and infants
5/0 Used for larger vessel repair such as an Abdominal Aortic Aneurysm
9/0, 8/0, 7/0, 6/0 surgery and for repairing small damaged nerves often due to lacerations in the hand. also used for repairing small vessels and arteries or for delicate facial plastic surgery.
10/0 Typically used in the most delicate surgeries. Common in both Ophthalmic (eye)
Therefore, having seen your photos, I would venture to suggest that the superficial layer beneath the skin, which should have been closed with something like a 3/0 suture, was most likely closed with a much thicker material, say size 0 or 1. Thus resulting in a situation where, being unable to fully digest a foreign body (the suture and most particularly the knot), your body does what it usually does under these circumstances which is to eject it by creating a simple abscess.
Hope this explanation helps.
