Temporary vs Permanent Ostomy

When a surgeon creates an ostomy, one of the first questions people ask is whether it will be for life or whether normal bowel or urinary function may one day be restored. The answer depends on a range of clinical factors: the nature of the underlying condition, the extent of surgery required, the patient’s general health, and the capacity of the remaining anatomy to function safely without a stoma. Understanding the distinction between a temporary and a permanent ostomy — and the factors that influence each — can help patients and carers prepare more effectively for what lies ahead.

What Makes an Ostomy Temporary or Permanent?

The terms temporary and permanent refer to the anticipated duration of the stoma, not to differences in its construction or daily management. Both types involve bringing a section of bowel or the urinary tract through the abdominal wall and securing it to the skin to form a stoma.

A temporary ostomy is created with the specific surgical intention of reversal at a later date. The bowel or urinary tract below the stoma remains in place, allowing reconnection once healing is confirmed or the original problem has resolved.

A permanent ostomy is created when the section of bowel or bladder that has been removed cannot be reconnected — either because it has been excised, because the sphincter muscles required for continence are no longer present, or because the risk of reconnection outweighs any benefit.

Common Reasons for a Temporary Ostomy

Protecting a Surgical Join (Anastomosis)

The most common reason for a planned temporary stoma is to divert the flow of intestinal contents away from a newly formed surgical join in the bowel, giving it time to heal without the stress of passing faeces. A loop ileostomy or loop colostomy is frequently used in this setting — for example, after low anterior resection for rectal cancer or following surgery to repair a perforated bowel.

Inflammatory Bowel Disease Flares

In Crohn’s disease or severe ulcerative colitis, a temporary stoma may be created to rest an inflamed or diseased section of bowel. In some cases, once inflammation is controlled and the bowel has recovered, reversal becomes possible. However, in ulcerative colitis treated by total colectomy, the outcome depends on whether a pouch procedure (such as an ileo-anal pouch) is planned, and this is not always suitable for every patient.

Trauma and Emergency Surgery

Bowel injuries from trauma, volvulus, or perforation may require emergency stoma formation. These stomas are often temporary, with definitive reconstruction planned once the patient has stabilised and the bowel has healed.

Common Reasons for a Permanent Ostomy

Rectal Cancer Requiring Abdominoperineal Resection

When a tumour is located very low in the rectum, close to or involving the sphincter muscles, complete removal of the rectum and anus (abdominoperineal resection) is required. Because the sphincter mechanism is removed, a permanent end colostomy is the only option for managing bowel function.

Bladder Cancer and Urostomy

A urostomy — most commonly an ileal conduit — is almost always permanent. It is typically created following surgical removal of the bladder (cystectomy), most often for muscle-invasive bladder cancer. Because the bladder itself is excised, there is no structure available for urine to be returned to.

Severe Functional Disorders

Conditions such as faecal incontinence that has not responded to other treatments, or severe pelvic floor dysfunction, may result in a permanent colostomy to improve quality of life when no viable reconstructive option exists.

Extensive Crohn’s Disease

When Crohn’s disease affects long segments of the small or large bowel, repeated surgery can leave insufficient healthy intestine to reconnect safely. In these circumstances, a permanent ileostomy may become necessary.

Types of Stoma and Their Relation to Reversibility

Stoma type	Typically temporary or permanent?	Notes
Loop ileostomy	Usually temporary	Created to protect a distal join; reversal is often planned within weeks to months
Loop colostomy	Often temporary	Used in emergencies or to protect a rectal repair
End colostomy	Often permanent	Depends on whether rectum is retained
End ileostomy	Either	May be permanent (after total proctocolectomy) or temporary
Urostomy (ileal conduit)	Almost always permanent	Usually follows cystectomy

The Reversal Procedure

A stoma reversal (also called a takedown or closure) reconnects the two ends of the digestive tract. Before proceeding, the surgical team will typically confirm that the remaining bowel is healthy — often using an examination such as a contrast enema or flexible endoscopy — and that the patient is fit for a further anaesthetic.

Reversal surgery carries its own risks, including anastomotic leak, wound infection, and the development of a hernia at the former stoma site. After reconnection, many patients experience a period of altered bowel habit — including urgency, frequency, or loose stools — before the bowel adapts. This adjustment period is normal and usually improves over weeks to months, though recovery varies considerably between individuals.

Practical Implications for Daily Life

Whether a stoma is intended to be temporary or permanent, the standard of daily care required is the same. Pouch changes, peristomal skin care, diet adjustments, and awareness of potential complications such as skin irritation or parastomal hernia apply equally to both. Approaching a temporary stoma with the same diligence as a permanent one supports better outcomes and smoother recovery when reversal eventually takes place.

It is also worth noting that the status of a stoma can change. A stoma created as temporary may become permanent if complications arise, if disease progresses, or if the patient is not well enough for further surgery. Honest, ongoing conversations with the surgical team are essential.

The Bottom Line

The distinction between a temporary and a permanent ostomy is determined by the underlying surgical anatomy and clinical circumstances, not by how the stoma feels or functions day to day. Both types require the same attentive daily care. The possibility of reversal should always be discussed openly with your surgeon, and realistic expectations set early — circumstances can and do change. Always consult your stoma care nurse or specialist clinician for guidance tailored to your individual situation; they are best placed to advise on your specific type of stoma, your surgical plan, and your long-term outlook.
