Is There a Catheter for Poop? Fecal Management Systems

Yes, there is essentially a catheter for poop. Known clinically as fecal management systems, these are soft silicone catheters designed to sit inside the rectum and divert liquid stool into a sealed collection bag. They are used primarily in hospitals, especially intensive care units, to manage patients with severe diarrhea or fecal incontinence who cannot get out of bed. The devices are more common than most people realize, and understanding how they work, when they help, and when they can cause harm fills in a picture that rarely gets discussed outside clinical settings.

How Fecal Management Systems Work

A fecal management system is a large-bore, flexible silicone catheter with a small inflatable balloon near its tip. A healthcare provider inserts the catheter into the rectum, then gently inflates the balloon with water or saline. The balloon serves two jobs: it holds the catheter in place and creates a seal against the rectal wall so stool flows into the catheter rather than leaking out. The other end of the catheter connects to a closed drainage bag, usually hung at the side of the bed. Liquid and semi-liquid stool travels through the tubing by gravity and collects in the bag, which nursing staff can empty or replace without disturbing the patient. The entire system is closed, meaning it is not open to the air, which reduces odor and limits the chance of environmental contamination.

The most widely recognized brand is the Flexi-Seal Fecal Management System, though several manufacturers now produce similar devices. These systems are designed for temporary use, typically days to a few weeks, not as permanent solutions. They work best when stool is loose enough to flow through the tubing. Formed or hard stool will not drain passively, which is why the devices are indicated primarily for diarrhea or very loose incontinence rather than for general bowel management.

When Hospitals Use Them

Fecal management systems are used almost exclusively in acute care settings. The typical patient is critically ill, bedridden, and dealing with frequent liquid stools that threaten to break down their skin or contaminate nearby wounds. Common scenarios include patients in the ICU with sepsis-related diarrhea, burn patients whose grafts or donor sites sit near the perineum, patients on tube feeding that causes loose stools, and patients with large sacral pressure ulcers that need to be kept clean to heal. The devices are also placed in patients receiving certain antibiotics or medications known to cause prolonged diarrhea.

Fecal management systems serve as tools for preventing skin irritation and a condition called incontinence-associated dermatitis, where prolonged contact with stool enzymes damages the skin around the buttocks and perineum. In intensive care, where patients are often sedated and unable to communicate discomfort, the skin can break down quickly without intervention.¹ The systems also help protect surgical wounds and reduce the need for constant linen changes, which in a busy ICU can consume enormous amounts of nursing time.

Protecting Skin and Controlling Infection Spread

One of the strongest arguments for fecal management systems is their ability to protect fragile skin. When a patient has diarrhea dozens of times a day, even careful cleaning and barrier cream application may not keep up with the damage. Stool contains digestive enzymes and bacteria that erode skin rapidly, and once the skin breaks down, the open tissue becomes an entry point for infection. Fecal management systems divert stool away from the skin entirely, reducing the risk of pressure ulcers and incontinence-related skin breakdown while also easing the emotional distress that comes with repeated episodes of soiling.²

Infection control is a separate but related benefit. In hospitals dealing with outbreaks of Clostridioides difficile (often called C. diff), a bacterium that causes severe diarrhea and spreads easily through contaminated surfaces, containing stool matters enormously. An in vitro trial comparing stool management systems found that these closed systems can limit or prevent environmental contamination with C. diff spores, which are notoriously difficult to kill with standard cleaning.³ For an ICU where multiple patients share space and staff move between beds, keeping C. diff spores locked inside a sealed bag rather than spread across bed linens is a meaningful infection-control advantage.

Risks and Complications

Fecal management systems are not risk-free, and the complications can be serious. The retention balloon that holds the catheter in place also presses against the rectal wall. Over time, that sustained pressure can cause rectal ulcers, which are areas of tissue damage that may bleed, sometimes heavily. Other potential complications include loss of anal sphincter tone, abdominal distention, bowel obstruction, and in rare cases, rectal perforation. The buildup of stool above the catheter can also contribute to pressure on the bowel wall, leading to tissue death in the area.⁴

Case reports illustrate how dangerous these complications can become. One published case described a 77-year-old woman who was readmitted to the hospital with massive rectal bleeding caused by a large ulcer from a fecal management device placed during a previous stay. She had been on blood thinners, which made the bleeding worse. The authors noted that balloon pressure should be relieved periodically to reduce the risk of this kind of injury.⁵ This is not an everyday occurrence, but it underscores the importance of monitoring any patient with a fecal catheter in place and not leaving the device longer than necessary.

Clinicians managing these devices are expected to check balloon pressure regularly, irrigate the tubing to prevent blockages, and assess the rectal tissue for signs of damage. When a device has been in place for an extended period, the nursing team has to weigh the ongoing benefit of stool diversion against the accumulating risk of rectal injury.

Who Should Not Have One Placed

Not every patient with diarrhea is a candidate for a fecal management system. There is a clear list of situations where placement is contraindicated:

• Recent surgery: patients who have had lower colorectal or anal surgery within the past year.
• Existing rectal injury: any rectal or anal wound, stricture, or narrowing.
• Severe hemorrhoids: the device can worsen bleeding and tissue damage.
• Rectal or anal tumors: the balloon could press against fragile tumor tissue.
• Fecal impaction: the catheter is designed for liquid stool, not for clearing a blockage.
• Inflammatory bowel disease: the inflamed rectal tissue is too vulnerable to tolerate balloon pressure.

These contraindications come from manufacturer guidelines and clinical literature.⁶

Beyond the formal contraindications, several patient-specific factors raise the risk enough that clinicians should think carefully before proceeding. Advanced age, severe underlying illnesses, a history of pelvic radiation therapy, and being on blood thinners or having a bleeding disorder all increase the chance of rectal complications from fecal management systems.⁷ For these patients, the decision involves a careful conversation between the medical team, the wound care nurse, and sometimes the patient or family about whether the benefits outweigh the risks.

External Alternatives That Stay Outside the Body

For patients who cannot tolerate an internal device, or whose stool is too formed for a rectal catheter, external fecal collection systems offer another option. These are essentially pouches that adhere around the anal opening with a skin-friendly adhesive, collecting stool as it passes without anything being placed inside the rectum. Some versions connect to low-level suction to help pull stool into the collection bag, which improves reliability when the seal is imperfect.

A systematic review and meta-analysis comparing different types of fecal collection devices found that all device categories reduced incontinence-associated dermatitis substantially compared to standard care. External anal pouch devices reduced the odds of dermatitis by roughly 86%, and anal catheter devices (the internal kind) reduced it by about 76%.⁸ Both approaches were far better than pads and manual cleaning alone. The external devices carry almost no risk of rectal injury, which makes them appealing for patients with contraindications to internal placement. Their main limitation is that they depend on a good adhesive seal, which can be difficult to maintain in patients with loose perianal skin, deep skin folds, or very frequent high-volume output.

In practice, the choice between internal and external devices often comes down to the volume and consistency of stool, the patient’s anatomy, and how well an adhesive seal can be maintained. Some ICUs start with external pouches and switch to an internal catheter only when the external approach fails to keep the skin dry.

Impact on Nursing Workload and Hospital Costs

Managing fecal incontinence the traditional way, with absorbent pads, frequent linen changes, cleaning, repositioning, and barrier creams, is extraordinarily labor-intensive. A budget impact analysis at two Canadian hospitals quantified the difference. In one hospital, nursing time spent on incontinence care for a typical patient dropped from nearly six hours a day with traditional methods to about two hours with a fecal management system. For complex patients, the reduction was even more dramatic, from over twelve hours to four. The material costs told a similar story: daily supply costs per patient were roughly 35% to 70% lower with the fecal management system, depending on patient complexity and hospital. When projected across all eligible patients at one of the hospitals, the annual savings reached over $600,000 in materials alone, and that calculation did not even include the value of the freed-up nursing time.⁹

These numbers reflect a reality that anyone who has worked in a hospital understands intuitively: cleaning up incontinence episodes around the clock is one of the most time-consuming tasks in critical care nursing. Every episode requires at least two staff members to safely turn the patient, clean the skin, apply barrier products, change the linens, and reposition the patient. In a busy ICU, those hours add up fast and pull nurses away from other patients. A fecal management system does not eliminate the need for monitoring, but it does collapse dozens of daily cleaning episodes into periodic bag changes and catheter checks.

What Patients and Families Experience

This is a topic that clinical literature tends to address in clinical language, but the human reality is simpler and harder. Fecal incontinence in the hospital is deeply distressing. Conscious patients report embarrassment, loss of dignity, and emotional suffering. For families visiting a critically ill loved one, witnessing repeated soiling episodes can add to their distress, and the smell in a shared hospital bay affects everyone nearby.

Fecal management systems address these problems directly. Experts in critical care have argued that these systems are integral not just to medical management but to preserving patient dignity, and that recognizing their role is part of providing the highest standard of care to critically ill patients.² A clinical evaluation of a fecal management device in bedridden patients found that most conscious patients reported little to no pain from the device, and that the closed system eliminated foul odors from the room. Caregiver stress scores also dropped meaningfully in the group using the device compared to those managed with traditional methods.¹⁰ That last point matters because burnout among ICU nurses is a growing problem, and reducing the physical and emotional burden of incontinence care is one small part of addressing it.

Fecal Incontinence in Children

Most of the research and product development around fecal management systems has focused on adults, particularly critically ill adults in ICUs. Fecal incontinence in children presents a different challenge. It affects a large number of children worldwide, many of them with congenital conditions like anorectal malformations or spina bifida, and the treatments developed for adults do not transfer well to pediatric patients.¹¹ Children’s rectal anatomy is smaller and more delicate, and the psychological dimensions of incontinence in a child, especially a school-age child, carry their own weight.

Bowel management programs for children tend to rely on scheduled enemas, dietary modifications, and medications to produce predictable bowel movements rather than on indwelling devices. In acute care situations where a child has severe diarrhea, clinicians may use smaller catheters or external collection devices adapted for pediatric use, but there is far less published evidence guiding these decisions compared to the adult literature. Families caring for a child with chronic fecal incontinence are often navigating with limited options and limited guidance, and the field remains underdeveloped relative to the need.

When a Surgical Diversion Is Considered

For patients whose fecal incontinence is not temporary, or whose wounds are so severe that a fecal catheter alone cannot keep them clean, surgeons may recommend a diverting colostomy. This is a surgical procedure that brings a section of the colon to the surface of the abdomen, creating an opening called a stoma through which stool empties into an external bag. It completely bypasses the rectum and anus, which is the most reliable way to keep stool away from a wound in the pelvic area.

A colostomy is a much bigger intervention than placing a fecal catheter, and it carries real surgical risk, especially in the frail, malnourished patients who typically need it most. A study of patients who received diverting colostomies for sacral pressure ulcers found that overall 30-day mortality was about 7%. Patients with very low blood protein levels had roughly double the mortality risk, and older age, preoperative sepsis, and other factors further increased the danger.¹² The title of that paper captures the situation well: what sounds like a straightforward procedure turns out to be anything but simple in this patient population.

This context helps explain why fecal management systems occupy such an important middle ground. They are far less invasive than surgery and can be placed at the bedside in minutes without anesthesia. For many patients, they buy enough time for a wound to heal or for diarrhea to resolve without ever needing an operating room. When the underlying problem is truly chronic, though, or when the catheter cannot be maintained safely, a colostomy may become the more durable solution despite its risks. The decision is always individualized, weighing surgical risk against the ongoing harm of uncontrolled fecal contamination.

Devices You Will Not Find Outside a Hospital

If you are reading this because you or a family member deals with fecal incontinence at home, it is worth knowing that fecal management systems of the type described here are not available over the counter or intended for home use. They require clinical assessment for safe placement, monitoring for complications like rectal ulcers, and periodic adjustments that need trained hands. Using a retention-balloon catheter without medical supervision carries serious risks including rectal perforation and uncontrolled bleeding.

Home management of fecal incontinence typically involves a different set of tools: absorbent pads and underwear, skin barrier creams, dietary adjustments to firm up stool, medications like loperamide to slow bowel transit, pelvic floor exercises for those whose incontinence stems from muscle weakness, and sometimes biofeedback therapy. For people with neurological conditions or spinal cord injuries, bowel programs that use scheduled stimulation and evacuation can establish enough predictability to make incontinence rare. External fecal pouches, the adhesive kind that do not go inside the body, are sometimes used in home settings for bedbound individuals, though adhesive management can be tricky without nursing support.

The gap between what is available in a hospital ICU and what a person can access at home remains wide. Several companies are working on devices designed for longer-term or less-supervised use, but regulatory approval and practical safety concerns have kept the most effective containment systems firmly within the clinical setting for now. If you are managing incontinence at home and struggling, a wound care or continence nurse specialist is the best resource for evaluating which combination of products and strategies fits your situation.
