Stoma Reversal Wound Healing: What to Expect

Most stoma reversal wounds take roughly two to four weeks to heal on the surface, though the deeper tissue underneath continues remodeling for months. The experience varies quite a bit depending on how the wound was closed, whether infection develops, and your overall health going in. What catches many people off guard is not just the wound itself but the changes in bowel function that come alongside it, which can take far longer to settle than the skin.

How the Wound Gets Closed and Why It Matters

When a stoma is reversed, the surgeon reconnects the bowel internally and then has to deal with the circular hole left in the abdominal wall where the stoma used to sit. There are two main ways to close the skin at that site: a straight-line (linear) closure, where the edges are stitched together in a line, and a purse-string closure, where a drawstring-style suture gathers the skin edges inward, leaving a small central opening that heals from the edges in.

The choice between these two techniques has a surprisingly large effect on infection risk. A Cochrane review of nine randomized trials involving over 750 patients found that purse-string closure reduced the risk of surgical site infection to about 5 percent, compared with roughly 24 percent for linear closure.

A separate prospective study found an even starker contrast: a 24 percent infection rate with linear closure and zero infections with purse-string closure.

The trade-off is healing speed. Because a purse-string wound heals by gradually filling in from the edges rather than healing along a closed line, it takes longer to fully close. That same prospective study reported an average healing time of about 14 days for purse-string versus about 11 days for linear closure.² For most people, the extra few days of healing is a worthwhile exchange for a much lower chance of infection and, ultimately, a better-looking scar. The Cochrane review noted that patient satisfaction was higher with purse-string closure.¹ A randomized trial comparing scar cosmesis between the two techniques confirmed that purse-string closure produced significantly better scar appearance scores.³

What a Typical Healing Timeline Looks Like

In the first few days after surgery, the wound site will be swollen, tender, and bruised. You can expect some drainage, which is normal and generally clear or slightly blood-tinged. If you had a purse-string closure, there will be a small open area in the center that looks like a shallow dimple. This gradually fills in with new tissue over the coming weeks. If you had a linear closure, the incision line should be held together with sutures or staples, which are typically removed around 10 to 14 days.

Surface healing for most patients falls in the range of two to four weeks, depending on the closure method. One small case series using negative-pressure therapy followed by delayed primary closure confirmed full epithelialization (the top skin layer growing over the wound) at a median of about 12 days.⁴ But this varies. If infection develops, the timeline can stretch dramatically. One study found that patients who developed a surgical site infection took a median of 91 days for wound healing, compared with 66 days for those who did not.⁵ That is a gap of nearly a month, and it underscores why infection prevention matters so much.

Even after the skin closes, the deeper layers of fascia and muscle continue healing and remodeling for three to six months. During this window, heavy lifting and intense core exercise are generally restricted. Your surgical team will tell you when it is safe to increase activity, but expect the full structural recovery to lag well behind the visible wound closure.

Wound Infection Risk

Stoma reversal sites are inherently prone to infection. The old stoma tract has been in contact with bowel contents, and the skin around it is colonized with gut bacteria. A large meta-analysis pooling over 8,500 patients found that the overall incidence of wound infection after stoma reversal is about 12 percent.⁶ Some individual studies have reported rates well above that. One single-center analysis of 128 patients found a 36 percent infection rate, which was associated with longer hospital stays, more reoperations, and higher readmission rates.⁵

Several risk factors come up consistently in the research:

Stoma type: Colostomies carry a higher infection risk than ileostomies.⁶
Higher BMI: Thicker subcutaneous fat around the wound site is one of the strongest predictors. One study found that fat thickness of 20 millimeters or more was associated with more than an eightfold increase in infection odds.⁷
Early reversal: Having the stoma reversed within about 20 weeks of its creation was linked to higher infection risk in the same study.⁷
Prior wound infection: If the original surgery that created the stoma was complicated by a surgical site infection, the reversal site is about three times more likely to become infected.⁶
Longer operations: Procedures exceeding 60 minutes were associated with a roughly fourfold increase in infection risk.⁶

One question patients often ask is whether subcutaneous drains reduce infection. A randomized trial found that skipping the subcutaneous suction drain after ileostomy reversal was not inferior to using one in terms of hospital stay, infection rates, or fluid collections.⁸ So the presence or absence of a drain at the stoma site is not something to worry about either way.

Negative Pressure Wound Therapy

You may hear your surgical team mention a vacuum-assisted dressing or “NPWT.” This involves placing a sealed dressing over the wound connected to gentle suction, which draws fluid away and promotes tissue growth. A meta-analysis of randomized trials found that negative pressure wound therapy shortened healing time by nearly four days compared with standard dressings.⁹

A randomized study found a median healing time of about 17.5 days with NPWT versus 21.5 days with conventional dressings, alongside far fewer dressing changes needed: a median of five with NPWT compared with 17 in the control group.¹⁰ The practical benefit of fewer dressing changes is significant when you are managing a wound at home. A separate non-randomized study found that patients using a portable negative pressure device (PICO dressing) attended community nursing visits an average of about twice, compared with roughly 12 visits for patients with conventional dressings. The PICO group also returned to daily activities within one to two weeks, while a third of the conventional group had not yet done so in the same timeframe.¹¹

One randomized trial struck a more cautious note, finding that while patients in the NPWT group reported less pain and higher aesthetic satisfaction, the difference in overall wound complications and infection rates did not reach statistical significance.¹² The technology is promising but not universally recommended, and not every hospital offers it routinely. If your surgeon does not mention it, it is reasonable to ask whether it would be appropriate for your situation.

Bowel Recovery in the First Week

While the wound is healing on the outside, your bowel is reconnecting and waking up on the inside. Most people pass their first stool two to three days after surgery and tolerate a soft diet by day three or four.¹³ Hospital discharge typically follows once you are eating, passing gas, and having bowel movements, which in a large study of 944 patients averaged about five days.¹³

Enhanced recovery programs, which include early mobilization, early eating, and targeted pain management, can speed this up. A randomized trial found that patients on an enhanced recovery protocol had their first stool at a median of three days compared with longer waits in standard care, and the gut started working about a day sooner across all measures.¹⁴ A meta-analysis confirmed that enhanced recovery protocols reduced time to first stool by about one day without increasing complications, readmissions, or reoperations.¹⁵ If your surgical team uses an ERAS protocol, expect to be sipping water within hours of surgery and eating soft food the next day.

Bowel Habits That Can Last for Months

This is the part that surprises many people. Even after the wound is fully healed, bowel function can remain unpredictable for weeks or months. Frequent loose stools, urgency, occasional incontinence, and clustering of bowel movements are all common. For people who had rectal cancer surgery with a temporary ileostomy, these symptoms overlap with what is called low anterior resection syndrome, and they can persist for years.

A qualitative study found that participants described being “tied to the toilet” after reversal, with bowel unpredictability dictating their daily routines.¹⁶ A large study looking at long-term outcomes found that patients who had a temporary ileostomy experienced more fecal incontinence and more severe bowel dysfunction even years after reversal compared with those who never had a stoma.¹⁷ The timing of reversal did not seem to affect these long-term outcomes, which suggests the issue is partly related to having had the stoma itself rather than to how long it was in place.¹⁷

For most people, the worst of the bowel irregularity improves gradually over the first three to six months. Pelvic floor exercises, dietary adjustments (smaller meals, avoiding high-fiber foods initially), and anti-diarrheal medication can all help during this adaptation period. But it is worth knowing going in that “reversal” does not always mean a complete return to pre-surgery bowel habits, especially after rectal surgery.

Incisional Hernia at the Old Stoma Site

The hole that was made in the abdominal wall for the stoma is a structural weak point even after it is closed. Incisional hernias at the former stoma site are surprisingly common and tend to develop over the first one to two years. Studies report rates in the range of 25 to 35 percent. One study following 318 patients for a median of two years found a hernia rate of about 35 percent.¹⁸ Two more recent studies reported rates of about 24 to 25 percent.¹⁹²⁰

The risk factors are consistent across these studies: higher BMI, a history of parastomal hernia before reversal, hypertension, diabetes, immunosuppression, and a larger stoma opening. Having had a colostomy rather than an ileostomy also carries a higher hernia risk, likely because the abdominal wall defect is larger.¹⁸ One study also identified delayed reversal (six months or more after stoma creation) and postoperative wound infection as independent risk factors for hernia development.²⁰

Not all hernias at the old stoma site need repair. Many are small, cause no symptoms, and are simply monitored. But if you notice a bulge at the stoma site that worsens with standing or straining, especially if it is painful, bring it up with your surgeon. Wearing a supportive abdominal binder during the first few months of recovery can provide comfort, though there is limited evidence that binders actually prevent hernias from forming.

Nutrition and Its Effect on Healing

Adequate nutrition matters for any surgical wound, but stoma reversal patients face a specific risk. Living with a stoma, especially an ileostomy, can make it harder to absorb nutrients and maintain weight. A study looking at nutritional status around the time of stoma reversal found that while having a temporary stoma did not necessarily cause severe malnutrition before surgery, a significant drop in albumin levels after the reversal operation was an independent risk factor for wound infection and other complications.²¹ Patients with very low postoperative albumin levels had a complication rate above 70 percent in that study.²¹

The practical takeaway is to focus on protein-rich foods and adequate calories both before and after surgery. If you have been struggling with weight loss or dehydration while living with your stoma, raise this with your team before the reversal date. Some surgical centers will delay reversal if nutritional markers are too low, and that delay can pay off in smoother healing.

When to Be Concerned

Some degree of redness, mild swelling, and clear or slightly pink drainage around the wound is expected during the first week. Signs that something has gone wrong include increasing redness spreading outward from the wound, cloudy or foul-smelling drainage, fever, or the wound edges pulling apart. If you notice stool draining from the wound site rather than from your rectum, that suggests an enterocutaneous fistula, a rare but serious complication where the bowel connection has leaked. One case report described stool drainage appearing at the takedown site about a week after surgery, requiring specialized wound management and ultimately further surgery.²²

Anastomotic dehiscence, where the internal bowel reconnection breaks down, is uncommon but is the most dangerous early complication. A study of patients undergoing stoma closure after severe peritonitis found a 10 percent rate of anastomotic breakdown, with older age being the most significant risk factor on multivariate analysis.²³ Symptoms can include sudden worsening abdominal pain, fever, rapid heart rate, and a feeling that something is seriously wrong. This is an emergency and requires immediate medical attention.

Patients on Immunosuppressive Therapy

People with inflammatory bowel disease who are on medications like infliximab, azathioprine, or steroids sometimes worry that their treatment will impair wound healing or increase complications after stoma reversal. One study comparing complication rates across patients on infliximab, other immunosuppressive drugs, steroids alone, and no immunosuppression found no significant differences in postoperative wound infection, hernia, obstruction, or other complications between the groups.²⁴ That said, the meta-analysis on risk factors for wound infection did identify inflammatory bowel disease itself as a risk factor, roughly doubling the odds of infection.⁶ The disease rather than the medication seems to be the issue, though the evidence is limited.

The Emotional Adjustment

Many people expect stoma reversal to feel like crossing a finish line, a return to the body they had before surgery. The reality is often more complicated. Research into the lived experience of stoma reversal patients has found that the anticipated return to normal can be blocked by a combination of physical and psychological challenges.²⁵ Unpredictable bowel function creates anxiety about being away from a bathroom, and some patients describe feelings of vulnerability and loss of control that are just as disruptive as having the stoma was.²⁶

If you find yourself struggling emotionally after reversal, particularly if bowel function is not improving as expected, connecting with a stoma care nurse or a support group can make a real difference. The adjustment period is a recognized phenomenon, not a personal failing, and the frustration tends to ease as bowel adaptation progresses over the first several months.
