Stoma prolapse is a condition in which the bowel telescopes outward through a stoma opening, producing a progressively longer tube of exposed intestine that can range from mildly annoying to medically urgent. It is one of the most common late complications of both colostomies and ileostomies, and while most cases can be managed without an emergency trip to the operating room, the condition has a frustrating tendency to come back even after surgical repair. Understanding what drives a prolapse, when to worry, and what the realistic treatment options look like can make a significant difference in how you or someone you care for navigates life with a stoma.
What Happens During a Stoma Prolapse
A stoma is a surgically created opening that brings a section of intestine to the skin surface so stool or urine can exit the body into a collection bag. In a prolapse, the bowel behind or around the stoma slides forward and everts, so what you see is an increasing length of moist, pink intestinal lining protruding beyond the skin. The protrusion can be just a couple of centimeters, or in severe cases it can extend dramatically. One published case report described a colostomy prolapse reaching 30 cm, with a loop of small bowel herniating into the everted segment.1PubMed Central.

Prolapse tends to be classified as a late stoma complication, meaning it usually develops weeks to months after surgery rather than in the first few postoperative days. Early complications are more commonly things like ischemia, retraction, or wound separation at the skin-stoma junction. Prolapse joins parastomal hernia, late retraction, and stomal varices on the list of problems that show up once a patient is home and living with their stoma.2PubMed Central.

Why It Happens
The basic mechanism involves increased pressure inside the abdomen pushing a mobile segment of bowel through the stoma opening. Anything that raises abdominal pressure, such as coughing, straining, or bearing down, can drive a loop of intestine outward if conditions are right. The key predisposing factor is having a section of bowel near the stoma that is redundant or overly mobile, meaning there is more slack in the intestine than necessary.3PubMed Central. Prolapse of intestinal stoma – Section: Abstract Detailed observations of transverse loop stomas have confirmed that prolapse typically starts at the mucocutaneous junction, where the bowel meets the skin, with the distal limb of the loop being the portion that prolapses outward as abdominal pressure is applied.4PubMed. Pathophysiology and prevention of loop stomal prolapse in the transverse colon
Several factors at the time of stoma creation can set the stage for later prolapse. If the surgeon cuts too large a hole through the abdominal wall fascia, the bowel has more room to slide. If the intestine is not anchored securely to the abdominal wall, or if an excessive length of bowel is left between the stoma site and the point where the intestine enters the abdominal cavity, the risk goes up. Using an extraperitoneal route, where the bowel is tunneled through the abdominal wall layers rather than left floating inside the peritoneal cavity, is one technique reported to help prevent prolapse.5PubMed Central. Prolapse of intestinal stoma
Colostomies Prolapse More Than Ileostomies
Not all stomas carry the same prolapse risk. Colostomies, particularly loop colostomies, are substantially more prone to prolapse than ileostomies. Multiple meta-analyses comparing the two in patients who had rectal cancer surgery have reached the same conclusion: loop ileostomies prolapse at significantly lower rates than loop colostomies.6PubMed Central. Complications of preventive loop ileostomy versus colostomy: a meta-analysis, trial sequential analysis, and systematic review One of these analyses put a number on it: patients with loop colostomies had roughly two and a half times the prolapse risk compared to those with loop ileostomies.7PubMed Central. Meta-analysis: loop ileostomy versus colostomy to prevent complications of anterior resection for rectal cancer
The difference probably comes down to anatomy. The colon, especially the transverse colon, tends to have more slack and mobility than the ileum (the last segment of the small intestine). A redundant transverse colon sitting near a generous stoma opening is more or less primed for prolapse every time intra-abdominal pressure rises. This is a meaningful consideration when surgeons are deciding which type of diversion stoma to create, although prolapse risk is only one factor in a decision that also involves rates of other complications like dehydration and skin irritation.
Recognizing a Prolapse and Knowing When It Is Urgent
A prolapse is usually obvious: you see more stoma protruding than before, and the length may change with position or activity, getting worse when you stand, cough, or strain, and sometimes retracting when you lie down and relax. The color of the prolapsed bowel matters. Healthy prolapsed stoma tissue should be pink and moist. Darkening toward a deep red, purple, or black signals that blood flow is being compromised, and that is when the situation becomes urgent.
The complications that turn a prolapse into an emergency are incarceration, where the prolapsed bowel cannot be pushed back in, and strangulation, where the blood supply to the bowel is cut off. Symptoms of these include increasing pain, swelling, and color changes in the stoma. Obstruction, where stool can no longer pass through the kinked or compressed bowel, is another serious possibility. In rare cases, the prolapse can be severe enough that other abdominal contents herniate through the stoma opening. Emergency surgery is needed when tissue has lost blood supply and begun to die.8PubMed Central.

Conservative Management and the Sugar Trick
Most stoma prolapses do not require immediate surgery. Conservative management, usually guided by a stoma care nurse, is the first-line approach. This typically involves gently reducing the prolapse by applying steady, even pressure to push the protruding bowel back through the stoma opening, then fitting an appropriate appliance to keep things stable. Lying down to reduce abdominal pressure helps. Cold compresses can shrink minor swelling before a manual reduction attempt. Surgical intervention is reserved for situations where the prolapse interferes with normal bowel function, causes complications like incarceration, or makes routine stoma care unmanageable.9PubMed Central. Prolapse of intestinal stoma
When the prolapsed bowel is so swollen that it cannot be pushed back in, an old and surprisingly effective technique involves sprinkling granulated sugar over the exposed tissue. The sugar draws fluid out of the swollen bowel by osmosis, shrinking the tissue enough that manual reduction becomes possible. This approach has been documented in multiple case reports as a way to avoid emergency surgery for an incarcerated prolapsed ileostomy.10PubMed Central. Granulated sugar to reduce an incarcerated prolapsed defunctioning ileostomy11PubMed. Reduction of an incarcerated, prolapsed ileostomy with the assistance of sugar as a desiccant Japanese clinicians have also reported success using sugar to reduce stoma edema in non-incarcerated situations, bringing down swelling over a few days when applied directly to the stoma surface.12PubMed. Application of Sugar to the Edematous Stoma for Obstructive Rectal Cancer-A Case Report The evidence base is small, mostly case reports, but the technique is low-risk and useful to know about, especially in situations where surgical resources are not immediately available.
If the stoma was created as a temporary diversion, the simplest definitive solution is to reverse it once the underlying reason for diversion has resolved. A prolapse in a diversion stoma is, in that sense, a problem with a natural expiration date.
Surgical Repair Options
When conservative management is not enough, several surgical approaches exist. A systematic review and meta-analysis of the surgical literature identified seven distinct procedures, which broadly fall into local (at the stoma site) or abdominal (through a larger incision) categories.13PubMed. Surgical treatment of stomal prolapse: A systematic review and meta-analysis of the literature The main options include:
- Local stoma reconstruction: The surgeon revises the stoma at the skin level, shortening the prolapsed segment and re-suturing it. This was the most commonly performed procedure in the literature.
- Stapled local repair: A linear stapling device is used to cut and seal the excess bowel at the stoma site, avoiding a major abdominal operation. The technique is relatively quick and can sometimes be done under sedation rather than general anesthesia.14PubMed. A novel, easy, and safe technique to repair a stoma prolapse using a surgical stapling device
- Modified Altemeier technique: Borrowed from perineal surgery for rectal prolapse, this method involves amputating the prolapsed segment and creating a new connection between the bowel ends at the stoma site. It can be performed under local anesthesia in frail patients who cannot tolerate a bigger operation.15PubMed Central. Stoma prolapse handmade repair under local anesthesia with variation of Altemeier method in severe patients: a case report and review of the literature
- Stoma relocation: The stoma is taken down and recreated at a different site on the abdomen.
- Laparotomy repair: A full abdominal operation to fix the bowel internally, anchor it to the abdominal wall, or address whatever is allowing the prolapse to occur.
The appeal of local and stapled repairs is clear: smaller procedure, faster recovery, no major abdominal incision. One series of stapled repairs reported success across multiple patients with no complications or recurrences.16PubMed. A novel, easy, and safe technique to repair a stoma prolapse using a surgical stapling device A broader evaluation of stapled repairs confirmed the approach is safe and minimally invasive with low recurrence.17PubMed.

The Recurrence Problem
The frustrating reality of stoma prolapse surgery is that the condition comes back at high rates no matter which technique is used. This is the single most important thing to understand about surgical management: you are not necessarily getting a permanent fix.
The systematic review mentioned above found that recurrence after local stoma reconstruction averaged about 37%, while stapled local repair fared better at roughly 15%. The modified Altemeier technique had a crude recurrence rate of about 20%, and stoma relocation, despite being a bigger undertaking, had the worst recurrence rate at around 67%.18PubMed. Surgical treatment of stomal prolapse: A systematic review and meta-analysis of the literature A separate study looking specifically at local versus abdominal approaches found recurrence rates that were essentially identical, roughly 43% for each, suggesting that a bigger operation does not buy you better long-term results.19PubMed. Surgical management of stomal prolapse – Is there a superior approach to repair? In that study, nearly half of patients whose prolapse recurred went on to have a third operation, often within the first year.
These numbers deserve some context. Recurrence rates in stoma prolapse surgery are calculated from relatively small case series, not large randomized trials, so the confidence intervals are wide and the real-world numbers could shift considerably with bigger studies. Still, the general picture is consistent across the literature: no approach has cracked the recurrence problem, and the stapled repair appears to offer the best combination of low invasiveness and reasonable durability. Surgeons weigh the patient’s overall health, the type of stoma, whether the stoma is temporary or permanent, and the severity of symptoms when deciding how aggressively to intervene.
Stoma Prolapse in Children
Children develop stomas for different reasons than adults. The most common indications in pediatric patients include Hirschsprung’s disease, anorectal malformations, and necrotizing enterocolitis in premature infants. Prolapse rates in children are generally higher than in adults. Published figures for pediatric stoma prolapse range from about 8% to 26%.20Surgical Science. Intestinal Stoma Prolapse and Surgical Treatments of This Condition in Children: A Systematic Review and a Retrospective Study One large single-center review of 473 pediatric colostomies found prolapse in about one in five patients.21PubMed. The mechanical complications of colostomy in infants and children: analysis of 473 cases of a single center
Certain underlying conditions push the risk much higher. Children with chronic intestinal pseudo-obstruction, a disorder where the gut cannot move food normally, had a stoma prolapse rate of 45% in one study, compared with 9% in children without that condition. Prolapse in these children also carried a 20% rate of intestinal necrosis, meaning the blood supply to the prolapsed bowel was lost, requiring bowel resection. Surgical management was needed in 60% of the pseudo-obstruction group.22PubMed. Stomal prolapse in children with chronic intestinal pseudoobstruction: a frequent complication? This is a stark reminder that prolapse in pediatric patients, especially those with motility disorders, needs close monitoring.
Living with a Stoma Prolapse Day to Day
For many people, a stoma prolapse does not require surgery and becomes something they learn to manage at home. That does not mean it is easy. A prolapsed stoma changes the profile of the opening, which can make it difficult to get a good seal with a pouching system. Poor appliance fit leads to leakage, and leakage brings its own cascade of problems: skin breakdown around the stoma, the constant anxiety of a potential leak in public, and withdrawal from social activities. Research on ostomates consistently finds that worry about leakage affects mental health, quality of life, and daily routines, with particular concern about the stoma being visible or odor escaping during social interactions.23PubMed Central. Stoma Leakage: Prevalence, Associated Factors, and Assessment Tools—A Scoping Review – Section: Psychosocial Factors
Stoma care nurses are the unsung heroes in prolapse management. They can help adapt your pouching system to accommodate the changing stoma size, teach you how to safely reduce a prolapse at home, and recognize when the situation has shifted from manageable to dangerous. If you have a prolapse that comes and goes, getting fitted with a flexible pouching system that can handle fluctuations in stoma height is often more practical than pursuing surgery, especially given the high recurrence rates associated with operative repair.
Practical steps that help include wearing supportive garments or stoma belts to keep the appliance in place, avoiding heavy lifting and activities that sharply raise abdominal pressure, and learning to reduce the prolapse yourself in a lying-down position. Keeping the exposed mucosa moist and protected when the prolapse is out is important to prevent trauma and drying. Many people find that the prolapse is worse at certain times of day or in certain positions and develop routines around that pattern.
Preventing Prolapse During the Original Surgery
Because prolapse is so difficult to fix permanently once it occurs, prevention at the time of stoma creation matters. Surgeons can reduce the risk through several technical choices: keeping the fascial opening as small as practical, securing the bowel to the abdominal wall with sutures, choosing a site along the intestine that minimizes the amount of redundant bowel near the stoma, and routing the bowel through the layers of the abdominal wall rather than through the open peritoneal cavity.24PubMed Central. Prolapse of intestinal stoma When there is a choice between a loop ileostomy and a loop colostomy for temporary diversion, the lower prolapse rate with ileostomies is one argument in favor of the small-bowel option, though other factors such as the risk of dehydration and electrolyte imbalance also weigh in.
Preoperative stoma site marking, ideally done by a stoma care nurse before the patient goes to the operating room, ensures the stoma ends up in a location on the abdomen that the patient can see and reach, away from skin folds, scars, and bony prominences. While site marking is primarily about pouching convenience and quality of life, choosing a site where the abdominal wall is firm and relatively flat also gives the stoma a better structural foundation and may reduce complication rates overall.
When the Prolapse Involves More Than Just the Stoma
Occasionally a stoma prolapse is not just the designated segment of bowel sliding out but a harbinger of something more complex. Parastomal hernias, where abdominal contents push through the abdominal wall next to the stoma, can coexist with prolapse and make the clinical picture more confusing. The case of the 30 cm colostomy prolapse mentioned earlier involved not only the prolapsed colon but also a loop of small bowel that had herniated into the everted colonic wall, creating a sac-within-a-sac that required careful surgical attention.25PubMed Central. Massive Colostomy Prolapse with an Intrastomal Ileal Hernia: A Case Report In another reported case, a prolapse was severe enough that the greater omentum, the fatty apron that drapes over the intestines, eviscerated through the stoma and developed necrosis, requiring emergency surgery to either return viable tissue to the abdomen or remove dead tissue.26PubMed Central. Colostomy orifice complications: a case report of a prolapsed colostomy with necrosis of the eviscerated greater omentum
These extreme presentations are rare, but they underline why any sudden change in a stoma’s appearance, especially if accompanied by pain, color change, or inability to pass stool, deserves prompt medical evaluation. The difference between a routine prolapse that you gently push back in while lying on your bed and a surgical emergency can come down to hours, particularly when blood supply is being compromised.
