How do I prepare for Colorectal Cancer surgery

Preparing for Colorectal Cancer Surgery

I'm glad you're thinking ahead about preparation—this is an important step in getting the best possible outcome. Let me walk you through what typically happens before surgery and how you can prepare.

BEFORE YOUR SURGERY: KEY PREPARATION STEPS

Medical Evaluation & Testing

Your surgical team will want to make sure you're in the best condition possible for surgery. According to NCCN Guidelines for Colon Cancer, you should expect:

• Complete preoperative colonoscopy (if not already done) to ensure there are no other polyps or cancers in your colon
• Imaging studies (CT scans of your chest, abdomen, and pelvis) to confirm the extent of your cancer and check for any spread
• Blood work to assess your overall health, kidney function, and blood counts
• Cardiac evaluation if you have heart concerns or risk factors

Bowel Preparation

This is crucial for colon surgery:

• Your surgeon will give you specific instructions about bowel cleansing (similar to what you'd do before a colonoscopy)
• You'll likely need to follow a clear liquid diet for 1-2 days before surgery
• You may receive laxatives or enemas to empty your colon completely
• This reduces infection risk and helps your surgeon see the surgical field clearly

Medication Management

• Tell your surgeon about ALL medications you take, including:
  • Blood thinners (aspirin, warfarin, etc.)
  • Diabetes medications
  • Blood pressure medications
  • Supplements and herbal products
• Some medications need to be stopped before surgery; others should continue
• Your surgical team will give you specific instructions

Nutritional Preparation

• Eat well in the weeks before surgery to build up your strength
• Stay hydrated
• If you're malnourished, your team may recommend nutritional supplements

PHYSICAL & PRACTICAL PREPARATION

Stoma Education (If Applicable)

If your surgery may result in a colostomy or ileostomy (an opening in your abdomen where waste exits into a pouch), NCCN Guidelines specifically recommend:

• Preoperative stoma education with an enterostomal therapist (a specialist nurse)
• Stoma site marking before surgery—the therapist will mark the best location on your abdomen
• Research shows this improves outcomes significantly

Questions to ask about stoma care:

• Will I definitely need a permanent stoma, or might it be temporary?
• What does stoma care involve?
• Can I see photos or videos of what a stoma looks like?
• Are there support groups for people with colostomies?

Lifestyle Adjustments

• Stop smoking if you smoke—even a few weeks before surgery helps
• Limit alcohol in the days before surgery
• Exercise gently if you're able (walking is good)
• Get adequate sleep in the weeks leading up to surgery

Arrange Support at Home

• Plan for someone to drive you home (you can't drive after anesthesia)
• Arrange help for 2-4 weeks after surgery for:
  • Cooking and meal prep
  • Household tasks
  • Childcare if needed
  • Pet care
• Stock your home with easy-to-prepare foods

SURGICAL APPROACH: WHAT TO EXPECT

According to NCCN Guidelines, your surgeon may use different techniques:

Open Surgery vs. Minimally Invasive Surgery

• Open colectomy: Traditional larger incision; longer recovery
• Laparoscopic colectomy: Several small incisions; shorter hospital stay (typically 5-7 days vs. 7+ days)
• Robotic-assisted surgery: May have benefits like less blood loss and faster bowel function recovery

Ask your surgeon:

• Which approach do you recommend for my specific cancer?
• What are the pros and cons for my situation?
• How experienced are you with minimally invasive techniques?

What the Surgery Involves

• Removal of the cancerous section of colon
• Removal of surrounding lymph nodes (at least 12 should be examined)
• Possible reconnection of the healthy colon ends (anastomosis) OR creation of a stoma
• Thorough exploration of your abdomen to check for spread

QUESTIONS TO ASK YOUR SURGICAL TEAM

About the surgery itself:

1. Exactly what part of my colon will be removed?
2. Will I need a temporary or permanent colostomy?
3. What are the risks and benefits specific to my cancer stage?
4. How long will the surgery take?
5. What's the expected hospital stay?

About recovery:

1. When can I return to normal activities?
2. What pain management options will be available?
3. What dietary changes should I expect after surgery?
4. Will I need adjuvant (follow-up) chemotherapy after surgery?

About your surgeon's experience:

1. How many colon cancer surgeries do you perform annually?
2. What are your complication rates?
3. Will you be doing the surgery, or will a resident assist?

AFTER SURGERY: WHAT TO EXPECT

According to NCCN Guidelines, after your surgery you'll need:

• Surveillance with imaging and blood tests (CEA levels) every 3-6 months for the first 2 years, then every 6 months for 5 years total
• Follow-up colonoscopy at 1 year after surgery
• Possible adjuvant chemotherapy depending on your cancer stage and risk factors
• Regular physical exams with your oncology team

KEY TAKEAWAY

The best preparation is clear communication with your surgical team. Don't hesitate to ask questions—understanding what to expect helps reduce anxiety and improves outcomes.

According to NCCN Colon Cancer Guidelines, patients who are well-informed and well-prepared tend to have better surgical outcomes and faster recovery.
