A Barbie butt / Ken butt for the guys refers to when you have had your rectum and anus removed and your backside sewn up. If you look at a doll, they rarely have any genital markings. Thus, those of us who have had this operation jokingly refer to it as having a Barbie butt.
This procedure is quite separate from the procedure that gives you a colostomy or ileostomy. The two can go together, but not always.
Sometimes the total rectal and anal removal is done because the bowel is so damaged that you will need a permanent - irreversible - stoma. If you are having a temporary stoma, no rectal/anal excision will be performed because you'll need it when your stoma is reversed.
However, in my case, I found that I needed a permanent and utterly irreversible colostomy after the temporary colostomy did not solve the health issues I was having. In order to improve my quality of life and get me comparatively pain-free, my surgeon operated on me for a second time and repositioned my stoma in its new permanent position. She also removed my sigmoid colon and over half of my descending colon. For an added bonus, she removed my badly dislocated coccyx in a lovely operation called a coccygectomy... try saying that drunk... LOL
My stoma is my life partner, and he has improved my quality of life considerably. Having the Barbie butt operation was just wonderful. It removed so many health issues and resulted in a much smoother existence. If you are having problems with hemorrhoids, fissures, bleeding, and other such delightfully painful and humiliating symptoms down there, a Barbie butt operation can be a true life and sanity saver. It was for me.
After the operations, I just laid around like a beached whale for a week or so because it was so uncomfortable wearing clothes that had waistbands. After a while, though, I found I was able to wear virtually anything. For laying by the pool, get one of the hernia protection waistbands and slip this over your pouch. It will keep everything in place and be supportive. You can get them in neutral tones, black, white, and beige. No one will be any the wiser that you have a stoma underneath them. Choose a color that teams with your bathing wear - black is good - and no one will notice a thing. They can be tight to pull up and into position, so do this somewhere discreet before you head on out to the beach or pool. Then you're not getting all hot and bothered struggling to get it on. They will roll up to just under the stoma appliance if you pull them down too far, so just make sure that they are positioned under the breastbone and above your hips. Then they won't humiliate you. You can get some that are underwear plus the waistband, but they have the tendency to look like granny knickers, which is not the look I personally am going for! But they are supportive. You can even wear them in water while you bathe; they just absorb the water and need a good wring out when you are finished. Chuck a sarong over your waistband and bathing wear, and you'll be fine.
Funnily enough, the colostomy gave me my confidence back! I've had it since 2010, and I'm wearing closer-fitting clothes now than I ever have. High-waisted pants and skirts and comfortable tops are my favs now. Before the colostomy, I used to wear baggy clothes and ill-fitting outfits because I wanted to disappear. Yay for the stoma. He's changed my life. I hope yours will change your life for the better too.
