Aren't they suppose to stitch, drain hole from the Tummy Tuck after they pull it out of the body?

It isn't necessary to stitch close the incisions where the drains are inserted because they are very small and heal well on their own. Normally, they are dressed with a bandage and in a bit they will close on their own. Just make sure to keep the are clean and not submerge yourself in a bath while they heal.

Thank you for your question. Most surgeons leave drain holes open to heal on their own to reduce the risk of an infection.  It is best to care for it by keeping it clean and covered with a small dressing like a Band-Aid. Ask you surgeon for recommendations for care of the drain site. Best wishes.

Drain holes will close on their own and don't need suturing. It will usually seal in a few days and have a scab that will come off within a few weeks.
