Crohn’s disease is a chronic inflammatory condition that can affect any part of the gastrointestinal tract. This inflammation causes deep ulcerations, scarring, and thickening of the bowel wall, leading to debilitating symptoms. The idea that all patients with Crohn’s disease will eventually need an ostomy, often referred to as a colostomy bag, is a common but inaccurate misconception. Treatment focuses on controlling the underlying inflammation to achieve and maintain long-term remission.
Medical Management: The Primary Approach
The standard approach to treating Crohn’s disease centers on using medications to suppress the overactive immune response that drives the inflammation. The goal is to induce remission, eliminating symptoms and allowing damaged intestinal tissues to heal. Medications are then used to prevent flare-ups and keep the disease inactive.
Corticosteroids like prednisone are often used temporarily for acute flares or moderate-to-severe disease activity due to their powerful anti-inflammatory effects. These drugs work quickly to reduce inflammation but are not suitable for long-term maintenance because of potential side effects. Long-term control is achieved using immunomodulators, such as azathioprine, which regulate the immune system to prevent future inflammatory cycles.
Biologic therapies target specific proteins involved in the inflammatory cascade, such as Tumor Necrosis Factor-alpha (TNF-α). These therapies are effective for moderate-to-severe Crohn’s disease unresponsive to other treatments. For milder cases, aminosalicylates, like mesalamine, may be used, particularly when the disease is limited to the large intestine. Supportive measures, including nutritional adjustments and specialized liquid diets, are employed to reduce stress on the digestive system and ensure adequate nutrient absorption.
Indications for Surgical Intervention
Surgery is generally reserved for complications of Crohn’s disease or when medical therapy has failed to control inflammation. The disease can lead to structural damage in the bowel that medications cannot repair, necessitating surgical intervention.
A common reason for surgery is the formation of intestinal strictures, which are narrowed sections of the bowel caused by scar tissue and chronic inflammation. When these strictures become severe, they can cause a painful intestinal obstruction, preventing the passage of food and waste. Other frequent complications include abscesses (pockets of infection) or fistulas (abnormal tunnels connecting the intestine to another organ or the skin).
Emergency surgery may become necessary for life-threatening events, such as a bowel perforation, which is a hole in the intestinal wall that spills contents into the abdominal cavity. Uncontrolled, severe gastrointestinal bleeding is an indication for immediate surgical intervention. Surgery is also required when the disease is refractory, meaning it has failed to respond to maximal medical therapies.
Surgical Options Beyond the Ostomy
Surgery for Crohn’s disease takes several forms, and many procedures do not result in a permanent ostomy. The most common procedure is a bowel resection, where the surgeon removes the diseased segment of the small or large intestine. The surgeon then reconnects the two healthy ends, a process called anastomosis. This procedure is performed to eliminate the source of complication, such as a severe stricture or fistula, while preserving as much healthy bowel as possible.
Another common procedure is stricturoplasty, which is designed to widen a narrowed section of the bowel without removing any of the intestine. The surgeon opens the stricture lengthwise and closes it horizontally, making the segment shorter but wider. This technique is often preferred for patients with multiple strictures, as it helps prevent the long-term complication of short bowel syndrome.
When an ostomy is necessary, it is most often an ileostomy in Crohn’s patients, which involves bringing the end of the small intestine (ileum) through the abdominal wall. A colostomy, which uses the large intestine (colon), is less common unless the disease is localized only to the colon. An ostomy may be temporary, allowing the rest of the bowel to heal before being reversed, or it may be permanent if the rectum or anus is too severely diseased to function.
Life After Ostomy Surgery
For many individuals with Crohn’s disease, having an ostomy can lead to a significant improvement in overall health and quality of life. The surgery removes the severely diseased sections of the bowel, eliminating chronic pain, urgency, and debilitating symptoms that were unresponsive to medication. Patients often find that they have more energy and can resume activities that were previously impossible due to their condition.
Practical management of the ostomy is streamlined with the help of specialized healthcare professionals, known as Wound, Ostomy, and Continence Nurses (WOCNs). These nurses provide comprehensive education before and after the operation, teaching patients how to properly use and change their pouching system. Modern ostomy appliances are discreet and secure, and many people successfully return to work, exercise, and active social lives.
While there is an adjustment period, support groups and peer resources offer emotional reassurance, helping patients adapt to the change in body image. Proper hydration is a concern, especially with an ileostomy, as the colon’s water-absorbing function is bypassed. With careful attention to fluid intake and diet, an ostomy often allows a return to a predictable and symptom-free existence.
