A colostomy bag is not always permanent. Many colostomies are created as temporary measures, designed to be reversed once the bowel has healed. Whether yours will be permanent depends on why it was placed, how much of the colon and rectum remain intact, and whether your body can handle a second surgery to reconnect the bowel.
When a Colostomy Is Temporary
A temporary colostomy diverts stool away from a damaged or healing section of the bowel, giving that tissue time to recover without waste passing through it. This is common after traumatic injuries like gunshot wounds or car accidents, after surgery for diverticulitis, or in newborns with certain birth conditions like Hirschsprung disease. Double-barrel colostomies, where the surgeon brings both ends of the divided colon to the surface, are usually temporary. So are ascending colostomies, which are placed higher up in the colon.
The goal with a temporary colostomy is always reversal. Once the downstream bowel has healed, a surgeon reconnects the two ends and closes the stoma. Most people live with a temporary colostomy for several months, though the exact timeline depends on how quickly healing progresses and whether any complications arise.
When a Colostomy Becomes Permanent
A colostomy is permanent when the rectum or anus has been removed, is no longer functional, or cannot safely be reconnected. The most common reason is a procedure called abdominoperineal resection (APR), the standard surgery for cancers located very low in the rectum. During APR, the surgeon removes the rectum and anus entirely, leaving no downstream passage for stool. There is simply nothing left to reconnect to.
Other conditions that lead to permanent colostomies include severe nerve damage affecting the rectum or anus, advanced inflammatory bowel disease that has destroyed too much tissue, and cancers that return after initial treatment. In some cases, a colostomy that was originally intended to be temporary ends up staying in place. About 20% of diverting ostomies created during rectal cancer surgery either remain unclosed or are converted to permanent ones. After a Hartmann’s procedure, a common emergency surgery for conditions like perforated diverticulitis, only about 44% of patients ever undergo reversal.
Surgical techniques have improved the odds of avoiding a permanent stoma, though. The rate of APR in rectal cancer surgery dropped from about 32% in 1998 to 19% in 2011 as surgeons developed better techniques for preserving the sphincter muscles.
What Determines if Yours Can Be Reversed
Before scheduling a reversal, your surgeon needs to confirm four things. First, the bowel must be fully healed with no leaks at the surgical connection point. Second, any disease that prompted the colostomy, whether infection, inflammation, or cancer, must be resolved or in remission. Third, the anal sphincter muscles and nerves need to be functional enough to control bowel movements after reconnection. If these muscles are weak, reversal carries a high risk of fecal incontinence. Fourth, your overall health has to be strong enough to tolerate another abdominal surgery.
If any of these criteria aren’t met, surgeons will advise against reversal, or at least delay it. A bowel that’s too short to reconnect safely, a return of the original disease, or frail general health can all take reversal off the table. About 6% of rectal cancer patients who initially have sphincter-sparing surgery end up with a permanent ostomy because their bowel function afterward is too poor to be manageable.
Living With a Permanent Colostomy
If you’ve recently learned your colostomy will be permanent, it’s worth knowing that adjustment tends to go better than most people expect. A study published in the International Journal of Environmental Research and Public Health found that patients with permanent stomas actually reported higher quality of life scores than those with temporary ones. That finding sounds counterintuitive, but the explanation makes sense: people with temporary colostomies often live in a state of psychological limbo, anxious about the upcoming reversal surgery and uncertain about the timeline. Those with permanent stomas, once they accept the change, tend to settle into routines and adapt.
Older adults in particular reported higher quality of life with a permanent stoma, likely because they had fewer competing lifestyle expectations and more time to develop comfortable management habits. This doesn’t mean adjustment is easy for everyone, but it does suggest that permanence, while initially daunting, is not the barrier to a full life that many people fear when they first hear the word.
Questions to Ask Your Surgeon
If you’re unsure where you stand, there are a few specific things worth asking. Was the rectum and anus preserved during surgery? If so, reversal is at least anatomically possible. Has the underlying condition fully resolved? Is there a timeline for reassessment? What testing will be done to check sphincter function before a reversal is considered?
The answers to these questions will tell you far more than the type of colostomy alone. Two people with the same diagnosis can have very different outcomes depending on the extent of surgery, how their body heals, and whether complications develop along the way. Your surgeon can give you a realistic picture based on your specific anatomy and recovery.
