I guess technically, I've had two reversals.
In June 2018, my intestines pretty much exploded with a massive infection. Diverticulitis. I went into the ER doolally and woke up with a colostomy in the ICU, cut from above my waist to my old C-section scar because of all the mess and infection the surgeon had to clean out. In October 2018, I went in for the reversal and got it, but another infection while I was in the hospital awaiting that all-important First Bowel Movement blocked everything up. Another emergency surgery, more slicing through the abdomen, and I woke up with an ileostomy. So, a little bit of experience with each! In late December 2018, the ileostomy was reversed, successfully this time.
I am a 68-year-old woman, still working, and do a decent amount of traveling, much of it to Europe (with and without the colostomy).
I was careful with my diet to begin with, chewing religiously, and had absolutely no problems with digestion, blockages, or cramps. More recently, I have even indulged in popcorn at the movies without incident. I'm a big believer in trying a little bit of what you fancy and chewing it well (as is my surgeon); if you have no problems, hooray for you! And now, over a year after the reversal, I eat whatever I want...and it's mostly healthy ;)
I have several small, soft bowel movements a day. Early on, there were some issues with urgency and I didn't like to stray too far from a known toilet, but that only lasted a few months. I do pass wind way too often, but...I'm also 68. Happily, my hemorrhoids cleared up, presumably due to their six-month vacation.
As far as my intestines are concerned, it was all a rousing success.
However...due to being cut through the abdomen three times in six months and my advanced years, I am still trying to build my muscles up. It took some physio to be able to walk upstairs (the abdominal muscles are, of course, connected to thigh muscles in particular), and I'm still rather entertaining when I get up from sitting or kneeling on the floor. I've got little strength in my abdomen, which means that my back muscles are holding me up on their own, and I get a sore back rather easily. The surgeon said it takes six months to a year for the intestines to heal, so I figured at my age I should err on the longer end before trying to strengthen those stomach muscles. I will admit to some paranoia whenever I get weird twinges with modified sit-ups and such, so I'm not making the progress I should be. I mention all this because it wasn't anything I had considered or expected. Of course, the patient's age, physical condition to start with, and whether the patient had such recent and repeated operations would come into play. It might not be an issue for you.
I knew from the jump that I would probably have a reversal, so my attitude toward the colostomy was probably very different from someone who was looking at this long-term. I am very happy that, even with a few bumps in the road, I was able to have a reversal and have found it to be successful. My surgeon did tell me that more than half the patients eligible for reversals don't have them. He said the statistics didn't include reasons, but the two of us speculated that fear (both of more surgery and of a potential future need for another colostomy), expense, and "the devil you know" might be the most common reasons.
I wish you good luck with your decision and, should you decide to reverse, your healing process. You'll make the best decision for you!
