Understanding Large Bowel Resection as a Treatment for Diverticulitis

Introduction and Terminology

Diverticulitis, a common gastrointestinal disorder, is often managed through a surgical procedure known as a Large Bowel Resection. This procedure involves the removal of a part of the large intestine (colon) that has been affected by the disease. In the context of diverticulitis, this typically means removing the section of the colon where diverticula—small, bulging pouches that can form in the digestive system—have become inflamed or infected.

The terminology related to this procedure includes “colon resection”, which is another name for the surgery, and “anastomosis”, a term that refers to the reconnection of the remaining parts of the colon after the diseased portion has been removed. Depending on the extent of the disease, a partial (segmental) or total colectomy may be performed. In some cases, a temporary or permanent colostomy may be needed, where an opening (stoma) is created on the abdomen to allow waste to exit the body into a colostomy bag.

Despite the availability of less invasive treatment options, Large Bowel Resection remains a primary treatment approach for severe or recurrent diverticulitis. Each year in the United States, over 300,000 people undergo some form of colectomy, indicating its prevalence in the management of various colon diseases including diverticulitis.

Indications for Large Bowel Resection

Large Bowel Resection is not typically the first-line treatment for diverticulitis, but there are several indications where this procedure may be recommended. These include:

• Recurrent diverticulitis: If you’ve had several episodes of diverticulitis that are causing significant discomfort, surgery may be recommended.
• Complicated diverticulitis: If your diverticulitis has led to complications such as abscesses, perforations, fistulas, or obstruction, surgical intervention is usually needed.
• Diverticular bleeding: This is a less common complication of diverticulitis, but if you experience persistent or severe bleeding, a Large Bowel Resection may be the best treatment.
• Failure of medical management: If antibiotics and other non-surgical treatments haven’t resolved your symptoms or if you’re unable to tolerate these treatments due to side effects, surgery may be an option.
• Immunocompromised patients: If you have a compromised immune system due to conditions like HIV/AIDS or medications like chemotherapy, surgery may be suggested after a single episode of diverticulitis to prevent further complications.
• Risk of colon cancer: In some cases, it may be difficult to distinguish between diverticulitis and colon cancer. If there’s a high suspicion of cancer, surgical intervention may be necessary.

Pre-Op Preparation

Preparing for a Large Bowel Resection involves several steps. Your physician will guide you through these based on your specific circumstances, but general recommendations include:

• Fasting for at least 8 hours before surgery.
• Adjusting your medication regimen as directed by your doctor, including potentially stopping certain medications before surgery.
• Completing pre-op labs or imaging studies, which provide valuable information to your surgical team.
• Securing pre-clearance authorization to ensure your procedure is covered by your insurance.
• Arranging transportation as you will not be able to drive home after the procedure.
• Obtaining work or school notes as necessary for your recovery time off.

Please note, it is critical to discuss all these steps with your physician to ensure they are appropriate for your specific situation. Certain circumstances might warrant different approaches. As a patient of our telemedicine primary care practice, you have the option to schedule a consultation to discuss your pre-operative preparation in detail, including any necessary adjustments to your medications and the ordering of pre-op labs and imaging. It’s essential to make sure you’re fully prepared for your surgery and the recovery that follows.

Procedure Technique for Large Bowel Resection

The Large Bowel Resection, or colectomy, is a procedure where the surgeon removes the diseased portion of your colon and then reconnects the healthy parts. It might seem overwhelming to understand the complexities of this surgery, but let’s break it down into simpler steps that can give you an idea of what your doctor will be doing during the procedure.

Preparation

The surgery generally begins with anesthesia. You will be given general anesthesia, which means you’ll be unconscious and will not feel any pain during the procedure. Once the anesthesia has taken effect, the surgeon will clean the area of your abdomen where the incisions will be made.

Approach to the Colon

The procedure can be performed using two techniques: open surgery or laparoscopic surgery. In an open colectomy, a single large incision is made in your abdomen. This gives the surgeon a direct view and access to the large intestine. Laparoscopic colectomy, on the other hand, involves making several small incisions. A laparoscope, a long tube with a camera on the end, is inserted through one of these incisions, giving the surgeon a magnified view of your colon on a screen. Other surgical instruments are inserted through the other incisions.

Removal of the Diseased Portion

Once the colon is accessed, the surgeon will locate the section of the colon that needs to be removed. This is the part of the large intestine that has been affected by diverticulitis. After identifying the diseased portion, the surgeon will disconnect it from the rest of the colon and the small intestine. If necessary, nearby lymph nodes might also be removed as part of the procedure. This is to ensure that any potential infection or disease has been fully removed from your body.

Anastomosis

After the diseased section of the colon has been removed, the remaining ends of the healthy colon are reconnected in a process known as anastomosis. This can be done in two ways: end-to-end or side-to-side. In end-to-end anastomosis, the two ends are directly sewn or stapled together. In a side-to-side anastomosis, one side of one end of the colon is connected to one side of the other end.

Creation of a Stoma (if required)

In some cases, it may not be possible to reconnect the colon right away. This is usually when there’s a need for the colon to heal, or in cases of severe infection. When this happens, a colostomy may be performed. In a colostomy, the surgeon makes an opening, or stoma, in the abdomen. The upper end of the large intestine is brought to this opening, and waste is passed out of the body into a bag that’s attached to the stoma.

Closure

Once the colon has been addressed, the surgeon will then close the incisions. If the procedure was an open colectomy, the incision will be sewn or stapled shut. If it was a laparoscopic colectomy, each small incision will be closed separately. Bandages will be applied to the site of the incisions.

This general overview provides a step-by-step breakdown of a Large Bowel Resection procedure. Remember that each patient’s situation is unique, so your surgeon might employ slightly different techniques based on your specific circumstances. It’s always important to discuss your procedure in detail with your healthcare provider to understand exactly what will be done during your surgery.

Duration of Large Bowel Resection

The duration of a Large Bowel Resection typically lasts between 2 to 4 hours. However, this can vary based on the individual patient’s condition and the complexity of the procedure.

Post-Op Recovery from Large Bowel Resection

Recovery from a Large Bowel Resection can take time and requires careful post-operative care. After the surgery, you can expect to stay in the hospital for approximately 3 to 7 days before being discharged, depending on your recovery progress.

Your follow-up schedule with your surgeon will typically involve a check-up 2 weeks post-surgery, then at 6 weeks, 3 months, 6 months, and then annually. The aim is to monitor your healing process, manage any postoperative complications, and ensure the best outcome.

Post-surgery rehabilitation may include gentle exercises and physical therapy to regain strength and promote healing. Certain lifestyle changes may also be recommended such as dietary modifications, managing stress, and incorporating regular exercise as per your doctor’s advice.

On average, expect to take at least 2-4 weeks off work after the surgery. However, recovery times vary significantly between individuals. A full recovery from a Large Bowel Resection can take up to 2-3 months or longer. Please note that our practice can see you the same day up until 9 pm on weekdays and 5 pm on weekends to provide work or school notes if necessary.

Effectiveness of Large Bowel Resection

Large Bowel Resection has proven to be a highly effective treatment for diverticulitis, particularly in severe cases or when other treatments have failed. Studies show that it provides relief from symptoms in a significant majority of patients.

The effectiveness of the procedure can be influenced by various factors. For instance, early diagnosis and treatment improve the success rate of the surgery. Overall health and lifestyle also play a significant role. Patients who maintain a healthy weight, stay active, and follow dietary recommendations tend to recover faster and have better outcomes.

However, certain situations or circumstances may lower the effectiveness of the procedure. These include advanced age, the presence of other chronic diseases like diabetes, obesity, and smoking. Severe or recurrent diverticulitis, as well as emergency surgery situations, may pose challenges in achieving optimal outcomes. Therefore, it is crucial to discuss with your healthcare provider your specific circumstances and the potential risks and benefits of the surgery.

Despite potential complications, Large Bowel Resection remains a cornerstone in the treatment of diverticulitis. It offers the potential for a significantly improved quality of life, and many patients report substantial relief from symptoms and a return to normal activities post-surgery.

Adverse Events with Large Bowel Resection

As with any surgical procedure, Large Bowel Resection carries potential risks and complications. These adverse events are relatively rare, but it is important to be informed about them.

• Wound infection (up to 15%): This occurs when bacteria enter the surgical wound, causing redness, swelling, pain, and possibly a fever. Antibiotics and proper wound care typically manage this complication.
• Anastomotic leak (about 3%): This is a serious complication where the newly connected areas of the bowel leak, causing infection or abscess. It often requires additional surgery.
• Bleeding (around 2%): Post-operative bleeding may occur and could require a blood transfusion or additional surgery in severe cases.
• Deep vein thrombosis (less than 1%): This is a blood clot in a deep vein, often in the leg. It can cause swelling, redness, or pain, and requires immediate medical attention.
• Pulmonary embolism (less than 1%): This is a potentially life-threatening condition where a blood clot travels to the lungs. It can cause shortness of breath, chest pain, and rapid heart rate.

The overall mortality rate associated with Large Bowel Resection is low, ranging from 1 to 3%. The risk of death is increased in elderly patients and those with multiple comorbidities.

Alternatives to Large Bowel Resection

If you have diverticulitis, several treatment alternatives to Large Bowel Resection exist. The best option depends on the severity of your condition and your overall health. Some alternatives include:

• Conservative management: This includes a high-fiber diet, exercise, and over-the-counter pain relievers. Antibiotics may be prescribed if infection is present.
• Medications: Anti-inflammatory drugs, antibiotics, or probiotics might be used to treat mild or recurrent diverticulitis.
• Minimally invasive surgery: In some cases, laparoscopic surgery might be an option. This procedure typically involves fewer complications and a shorter recovery period than a Large Bowel Resection.

Experimental or Emerging Technologies

Research is ongoing to find new and effective treatments for diverticulitis. Some emerging technologies and treatments include the use of fecal microbiota transplantation (FMT). This experimental treatment involves transferring the fecal bacteria from a healthy individual to a patient with diverticulitis in the hopes of restoring healthy gut flora. Early studies have shown promise, but more research is needed to confirm its effectiveness and safety.

Conclusion

Undergoing a Large Bowel Resection is a significant decision. It is crucial to understand the procedure, its effectiveness, possible adverse events, and alternatives.
