🔍 What Is Robotic Colorectal Cancer Surgery?

Robotic colorectal cancer surgery is a minimally invasive surgical procedure used to treat cancer affecting the colon or rectum. Instead of making one large incision, the surgeon uses small incisions and robotic-assisted instruments to remove the cancerous section of the bowel along with nearby lymph nodes when medically required. In colon cancer surgery, the affected part of the colon is removed, and the healthy ends of the bowel may be reconnected when safe and appropriate. Robotic colorectal surgery is not only about removing the visible tumor. It also involves careful cancer staging, lymph node assessment, margin planning, bowel function preservation, and coordination with other cancer treatments such as chemotherapy, radiation therapy, or targeted therapy when indicated. At Asan Medical Center, colorectal cancer care is supported by a multidisciplinary and integrated treatment model. The hospital highlights collaboration among relevant specialties for colorectal cancer cases involving liver metastasis, lung metastasis, locally recurrent disease, and intractable colorectal cancer.

🩺 Types of Robotic Colorectal Cancer Surgery

  • Robotic Right Colectomy – Removes cancer located in the right side of the colon, often with nearby lymph nodes for staging and cancer control.
  • Robotic Left Colectomy – Removes cancer affecting the left side of the colon while preserving as much healthy bowel as possible.
  • Robotic Low Anterior Resection – Used for selected rectal cancers where the tumor can be removed while preserving the anal sphincter.
  • Robotic Total Mesorectal Excision – A specialized rectal cancer surgery focused on removing the rectum and surrounding cancer-bearing tissue with precision.
  • Robotic Abdominoperineal Resection – Used when very low rectal cancer requires removal of the rectum and anus, usually with permanent colostomy.

🩺 Who Is a Good Candidate?

Robotic colorectal cancer surgery may be suitable for patients who need surgical treatment for colon cancer, rectal cancer, or selected complex colorectal tumors. A full evaluation is required to confirm whether robotic surgery is appropriate, as treatment depends on tumor location, cancer stage, overall health, previous treatments, and imaging findings.

✔️ Patients diagnosed with colon cancer or rectal cancer
✔️ Individuals with early-stage or localized colorectal cancer
✔️ Patients with selected locally advanced rectal cancer after specialist review
✔️ Individuals who may benefit from minimally invasive colorectal surgery
✔️ Patients who require tumor removal with lymph node dissection
✔️ Patients seeking colorectal cancer surgery in South Korea
✔️ Individuals who need a multidisciplinary cancer treatment plan
✔️ Patients who may require surgery after chemotherapy or radiation therapy
✔️ Individuals with recurrent colorectal cancer needing complex evaluation
✔️ Patients with stable heart, lung, kidney, and general health status
✔️ Patients who can safely tolerate anesthesia and abdominal surgery

📝 Consultation & Preparation

A careful consultation and preparation process is essential before robotic colorectal cancer surgery. Patients are usually evaluated through medical history, cancer staging, imaging, pathology review, and specialist consultations to determine the safest and most effective treatment plan.

✔️ Review of colonoscopy report and biopsy results
✔️ Evaluation of pathology confirming colorectal cancer diagnosis
✔️ CT, MRI, PET-CT, or other imaging when required for staging
✔️ Rectal MRI or endorectal ultrasound for selected rectal cancer cases
✔️ Blood tests, tumor markers, liver function tests, and general health screening
✔️ Assessment by colorectal surgery and oncology teams
✔️ Discussion of whether robotic, laparoscopic, or open surgery is most appropriate
✔️ Explanation of possible bowel reconstruction or stoma requirement

🩺 Recovery & Aftercare

Recovery after robotic colorectal cancer surgery depends on the type of surgery performed, cancer stage, overall health, and whether bowel reconstruction or stoma formation is required. Many patients experience gradual improvement after minimally invasive surgery, but recovery still requires careful monitoring and long-term follow-up.

✔️ Hospital monitoring after surgery for pain control and early recovery
✔️ Gradual return of bowel function before diet progression
✔️ Early walking to support circulation and reduce complication risk
✔️ Careful monitoring for fever, bleeding, infection, leakage, or bowel obstruction symptoms
✔️ Pain medication and antibiotics when prescribed
✔️ Wound care for small incision sites
✔️ Stoma care education if a temporary or permanent stoma is needed
✔️ Guidance on diet, hydration, and bowel habits after colorectal surgery
✔️ Avoiding heavy lifting and strenuous activity during early healing

  • ASAN Medical Center is a leader in research and medical care. I was unable to get medical help here in the United States due to a lack of professionalism and discrimination. After, two years of research and a business trip to South Korea, I learned about ASAN Medical Center. I knew through research that they were the best in the world and I was determined to seek answers for my condition. It took 3 months but I was elated when Professor Ko ( who specializes in Gastric cancer, Robotic Surgery, Bariatric, and Metabolic Surgery, Hernia Surgery) was assigned to my case. In December of 2023, I was traveling again to South Korea and spent a week going through a plethora of tests. I was in awe of the care, and respect as a patient which I received, and the best part was Dr. Ko took the time to explain to me in detail what was discovered and the next steps. I remember crying alone on New Year's Day in my hospital room, for the first time there was hope. In 2024, I underwent 2 successful surgeries. In the United States, after the surgeon performs the surgery you never see nor hear from them. Getting access is impossible! Not at ASAN Medical Center. I saw Dr. Ko and Dr. Yoo every day and the rest of the medical team including the head nurse. My wounds were cleaned constantly by a wound care nurse, I had nurses every hour to 2 hours to check-in, and the International Nurse, Nurse Park checked on me daily. I also had the honor of working with a phenomenal nutritionist who is still instrumental in how I eat. I was never made to feel alone given that I was far away from home and going through a scary process by myself. I was treated as a human being for the first time and was never treated differently because of the color of my skin. As a patient at ASAN Medical Center, the patient matters. I had real conversations with my surgeons, I was not only healing physically but mentally and spiritually. I was given a second chance, a chance to live, a chance to be healthy, and a new journey to become better than before. I was so sad when I was leaving. However, I was provided with the tools to keep healing. I encourage everyone to think outside the box and seek other options. ASAN Medical Center was my best option and can be yours too. Now, I plan to travel to South Korea to ASAN Medical Center every year for my follow-ups and annuals. I will never trust anyone else with my health. Dr. Ko is a genius. There are no words to describe his incredible mind and brilliance. Dr. Yoo is not an ordinary surgeon, his phenomenal approach to patient care and his tireless efforts in ensuring that his patients succeed is phenomenal. They are both my rock throughout this process. I was blessed to have a great team and you can too. Never lose hope especially when you feel you cannot go on anymore. Keep fighting! ASAN Medical Center is far more advanced in technology, patient care, research, and professionalism than any hospital I have been to. Thank you, Professor Ko, Dr. Yoo, Nurse Park, the nurses, the staff, International Department! I highly recommend ASAN Medical Center to every patient. Seek the International Center-Nurse Jenny Park is the best! If you have similar needs to me, I highly recommend Dr. Ko and Dr. Yoo.

    The staff in the emergency room were all extremely helpful, professional, and friendly. Highly recommend for their awesome services! One of the patrol guys was super nice and went extra miles to help us booked a venti taxi as foreigners can't really book a 5 pax car. So thankful to meet someone so nice in our journey 💓 Great food selection in this hospital. They even have nasi goreng (Malaysia fried rice) here lol feels like home. The only slightly bad experience was the receptionists can't speak English/Chinese, but it's their attitude that disgust us the most. One of the lady receptionists rolled her eyes on me when I speak English. I don't think that's the best way to treat anyone esp in a professional setting. To Asan Management, please train your receptionists to be more professional in attending patients/visitors enquiries.
