Understanding Colostomy: A Procedure to Treat Bowel Obstruction

Introduction and Terminology of the Procedure

A colostomy is a surgical procedure designed to provide an alternative pathway for fecal waste to exit the body. This is achieved by creating an opening, called a stoma, in the abdominal wall and connecting it to the colon. The procedure is often required when conditions such as bowel obstruction prevent the normal functioning of the digestive system.

Annually in the USA, there are approximately 120,000 colostomy surgeries performed, emphasizing its critical role in gastrointestinal healthcare. Key terms associated with this procedure include the stoma (the external opening), colostomy bag (the external pouch that collects fecal matter), and ostomy (a general term referring to any surgery creating an opening in the body).

Indications for Colostomy

The need for a colostomy can arise from various medical conditions that prevent the proper functioning of the colon. These include:

• Bowel obstruction: A blockage in the colon can halt the passage of feces, causing severe discomfort and potentially life-threatening complications. A colostomy can bypass the obstruction, allowing waste to exit the body.
• Inflammatory bowel disease: Conditions such as Crohn’s disease and ulcerative colitis can cause severe inflammation and damage to the colon. In some cases, a colostomy is necessary to manage these conditions.
• Colon or rectal cancer: A colostomy may be performed as part of the treatment plan for these cancers, either temporarily to allow healing post-surgery or permanently if a large section of the colon must be removed.
• Diverticulitis: This condition involves inflammation of pouches (diverticula) that can form in the colon wall. If severe, it may necessitate a colostomy.
• Abdominal or pelvic injury: Injuries to the lower abdomen or pelvic area can sometimes damage the colon, necessitating a colostomy.
• Birth defects: Some children are born with defects in their colon or rectum that require a colostomy.

Ultimately, the decision to undergo a colostomy is made in close consultation with your healthcare provider, based on the specifics of your condition and overall health.

Pre-Op Preparation

Preparing for a colostomy procedure involves several important steps to ensure your safety and the success of the surgery:

• Fasting: You may be asked to avoid eating or drinking for a certain period before the surgery, often from midnight the night before.
• Medication adjustments: Some medications may need to be stopped or adjusted before surgery. It’s essential to discuss all medications you’re taking with your doctor, including over-the-counter drugs and supplements.
• Pre-op labs or imaging: Various tests, including blood tests and imaging studies, may be needed to assess your overall health and plan the surgery.
• Pre-clearance authorization: Your insurance provider may need to authorize the procedure. Ensure this is completed in advance to avoid delays.
• Transportation and work/school notes: You’ll need to arrange transportation home post-surgery, and obtain any necessary documentation for time off work or school.

Please note that the specifics of pre-operative preparation can vary depending on individual circumstances. Always consult your healthcare provider for personalized advice. Our telemedicine primary care practice is available to assist with pre-operative clearances and ordering of pre-op labs and imaging as needed.

Procedure Technique for Colostomy

A colostomy is a complex procedure that involves careful preparation, precision during surgery, and diligent care afterwards. Here, we’ll guide you through the step-by-step process that your surgeon follows to perform a colostomy. Keep in mind that every patient’s experience is unique, and your surgeon will tailor the procedure to your specific needs.

1. Anesthesia

First, you’ll be given general anesthesia, a type of medicine that will make you sleep deeply and not feel pain during the surgery. The anesthesia will be administered by a specialist known as an anesthesiologist, who will monitor your vital signs throughout the procedure.

2. Incision

The surgeon will make an incision in your abdomen. This can be done in one of two ways:

• Open colostomy: The surgeon makes a larger incision in the middle of your abdomen to access the colon.
• Laparoscopic colostomy: Several smaller incisions are made for the insertion of a camera (laparoscope) and surgical instruments. This minimally invasive technique often leads to faster recovery and fewer complications.

3. Creating the Stoma

The surgeon will locate the section of the colon that needs to be brought to the surface. Once this part of the colon is identified and separated from the surrounding structures, the surgeon will gently pull it through the abdominal wall to create the stoma, or opening.

4. Securing the Stoma

Once the stoma is created, it will be sutured, or stitched, to your skin. This is done to secure the stoma and prevent it from retracting back into the abdomen. The stoma is usually round or oval and located on the right or left side of your abdomen, depending on the part of your colon that is involved.

5. Attaching the Colostomy Bag

A special pouch, known as a colostomy bag, will be placed over the stoma. The bag collects stool that exits the body through the stoma. The bag is discreet and is not noticeable under clothing. Your healthcare team will teach you how to attach, empty, and clean the bag.

6. Closing the Incision

Once the stoma is in place and functioning, the surgeon will close the abdominal incision. This is typically done with sutures or staples, which will be removed after the wound has had time to heal. If you had a laparoscopic colostomy, the smaller incisions may be closed with dissolvable sutures or special surgical glue.

7. Recovery Room

After the procedure, you’ll be taken to a recovery room, where your vital signs will be closely monitored as you wake up from the anesthesia. You might feel groggy and disoriented initially, but these effects will gradually wear off.

The detailed specifics of your colostomy may vary depending on factors like your overall health, the reason for your surgery, and your surgeon’s expertise. It’s important to discuss any concerns or questions you have with your healthcare team before the procedure.

Duration of Colostomy

The duration of a colostomy procedure can vary depending on individual factors and the type of colostomy, but typically, the surgery takes about 1-3 hours.

Post-Op Recovery from Colostomy

Recovery from a colostomy procedure is a process that involves time and adjustment. Immediately after the procedure, you’ll be monitored in the hospital for several days, with the average stay being about 3 to 7 days, depending on your overall health and how well you recover.

Once you’re discharged, follow-up appointments with your surgeon will be scheduled to monitor your progress. These will initially be frequent, often once a week, but as you recover, the visits will be spaced out more.

Physical therapy or rehab may be recommended to strengthen your abdominal muscles and help you adapt to the changes. Lifestyle modifications will also be necessary, particularly regarding diet and the care of your stoma and colostomy bag. With time, these changes will become part of your routine.

As for work, you may need to take anywhere from a few weeks to a couple of months off, depending on the nature of your job and how quickly you recover. Full recovery from a colostomy can take several months.

If needed, our telemedicine primary care practice offers extended hours for same-day appointments to provide any necessary work or school notes.

Effectiveness of Colostomy

The effectiveness of a colostomy in treating bowel obstruction is quite high, with studies showing a significant improvement in quality of life for many patients post-procedure. A colostomy effectively bypasses the obstructed section of the bowel, allowing waste to be eliminated and reducing symptoms like pain and bloating.

The success of a colostomy often depends on several factors. A good surgical outcome and proper stoma care are crucial, as is adhering to dietary guidelines post-surgery. A supportive care team, including a stoma nurse, can greatly enhance the patient’s adaptation and stoma management, thus improving the procedure’s effectiveness.

However, certain circumstances can reduce the effectiveness of a colostomy. These include the presence of other diseases or conditions, poor nutritional status, and complications during or after surgery. It’s also important to note that while a colostomy can significantly alleviate symptoms, it is not a cure for the underlying disease causing the obstruction.

Regular follow-ups with your healthcare provider are crucial in managing a colostomy and addressing any issues that may arise. The ultimate goal is to ensure that you can return to most of your normal activities while managing your symptoms effectively.

Adverse Events with Colostomy

Like any surgical procedure, colostomies carry a risk of adverse events. Some of these include:

• Stoma complications (up to 70%): These can include issues like stoma retraction, prolapse (the stoma becomes longer and may protrude), or hernias around the stoma. These problems often relate to the stoma’s construction or care.
• Skin irritation (up to 60%): This can result from leakage of stool onto the skin around the stoma, which can cause redness, pain, and even breakdown of the skin if not properly managed.
• Infection (around 10%): As with any surgery, there’s a risk of infection at the surgical site or internally. This typically presents with symptoms such as redness, swelling, fever, or unusual discharge from the stoma.
• Blockage or obstruction (around 15%): This can occur if the intestine becomes twisted or kinked, or if a large piece of undigested food blocks the stoma.
• Parastomal hernia (10-50%): A parastomal hernia occurs when a part of the intestine pushes through an opening in the muscles around the stoma, causing a bulge or swelling.

The mortality rate from the procedure is low, with studies suggesting it’s less than 2%. However, this can increase with patient age and the presence of other serious medical conditions.

Alternatives to Colostomy

While a colostomy can be an effective treatment for bowel obstruction, other options may also be suitable, depending on the specific circumstances. These could include medications to manage symptoms, dietary changes to reduce the risk of blockages, or other surgical interventions like an ileostomy or internal bowel resection. Additionally, temporary procedures like a stent placement can sometimes be used to open the obstructed area of the bowel.

Experimental or Emerging Technologies

There are ongoing developments in the field of gastroenterology, including treatments for bowel obstructions. One example is the use of self-expanding metal stents, which are inserted into the bowel to open up the blocked area, often as a temporary measure before surgery. Additionally, advancements in laparoscopic and robotic surgery continue to evolve, potentially offering less invasive methods for treating bowel obstructions in the future.
