Keloid scars are difficult but not impossible to treat. Based upon the appearance of the keloids ( in the photos), your best option would be a combined approach consisting of surgical excision/ reconstruction followed by immediate radiation therapy commencing on the day of surgery. Typically four or five radiation treatments are required. This is currently the best approach to prevent recurrence of the keloids. Good luck !
Drains are placed to prevent fluid from collecting at the operative site. It would not be unusual to remove one of your drains at the first post operative visit ( depending on the fluid output). In your case this sounds like tomorrow or post op day #5. The fact that one drain fell out today (post op day #4) may not be an issue ,as long as, the remaining drain can be secured . If there is a "tab" on the collection device of the drain, you can use a safety pin to secure it to your binder or clothing.
