Rectal cancer is a significant health concern affecting millions of people worldwide. When it comes to fighting this disease, understanding the different options for rectal cancer surgery plays a crucial role. These surgical choices vary widely and are vital in treating rectal cancer effectively while considering each patient’s unique situation.

Globally, rectal cancer ranks among the most common types of cancer, impacting approximately 1.8 million individuals every year. The number of cases varies worldwide due to lifestyle differences, healthcare access, and screening practices.

The diverse array of rectal cancer surgery options offers hope in combating this illness. These options range from minimally invasive procedures to more extensive surgeries, aiming to remove cancer while preserving the best possible quality of life for patients. 

Understanding these options empowers patients and healthcare providers, allowing for informed decision-making and personalised treatment plans. This blog will explore the various types of surgeries available, their global impact, and their significance in the fight against rectal cancer.

What is the Significance of Surgical Interventions?

The significance of surgical interventions in the context of rectal cancer treatment is multifaceted and pivotal in addressing this formidable disease. Here are key points highlighting the importance of surgical interventions:

• Primary Treatment Method: Surgery often serves as the immediate treatment for localised rectal cancer, aiming to remove the tumour and affected tissues from the rectum. It is critical in potentially curing the disease, especially in early-stage cancers.
• Tumour Removal: Surgical procedures are designed to eliminate cancerous growths from the rectum, preventing further spread and reducing the risk of recurrence. This removal is crucial in halting the progression of the disease.
• Preservation of Bowel Function: Surgeons strive to preserve normal bowel function whenever possible, aiming to maintain patients’ quality of life after surgery. Techniques focus on minimising the impact on bowel movements and continence.
• Personalised Approach: Surgical interventions are tailored to each patient’s specific condition, considering factors such as tumour size, location, and overall health. This customized approach ensures the most suitable treatment strategy for individual cases.
• Integration with Other Therapies: Surgery often complements other treatment modalities like chemotherapy and radiation therapy, enhancing their effectiveness and overall outcomes in managing rectal cancer.
• Advancements in Techniques: Ongoing advancements in surgical techniques, such as minimally invasive procedures and robotic-assisted surgery, contribute to reduced postoperative complications, shorter recovery times, and improved patient experiences.
• Long-term Survivorship: Successful surgical interventions can lead to prolonged disease-free periods and improved long-term survival rates, offering hope and a better prognosis for patients diagnosed with rectal cancer.

What are the Different Types of Rectal Cancer Surgery?

Let’s explore the main surgical options available for treating rectal cancer, ranging from minimally invasive to more advanced interventions.

a) Local Excision

This minimally invasive procedure, known as local excision, is designed to target small, early-stage tumours situated on the inner lining of the rectum. It is specifically recommended for lesions that haven’t profoundly penetrated the rectal wall. Employing specialised techniques, local excision offers a precise and focused approach to removing these less aggressive cancers, aiming to eliminate the tumour while preserving surrounding healthy tissues effectively.

Dr. Deep Goel states, “Local excision can be a game-changer for early-stage rectal cancer. It allows for effective tumour removal with minimal disruption to bowel function, helping patients maintain a good quality of life.”

b) Resection Surgeries

• Low Anterior Resection (LAR): A standard procedure for tumours located in the upper rectum. Surgeons remove the affected portion of the rectum and reconnect the healthy parts, preserving anal function.
• Abdominoperineal Resection (APR): In cases where the tumor is very low in the rectum or close to the anus, the entire rectum, anal canal, and sometimes the anus are removed. A permanent colostomy is necessary to divert bowel movements into an external bag.

c) Transanal Endoscopic Microsurgery (TEM)

Transanal Endoscopic Microsurgery (TEM) represents a specialised approach tailored for specific early-stage rectal cancers that haven’t extensively infiltrated the rectal wall. This technique entails the insertion of minute surgical instruments and a tiny camera through the anus. By doing so, surgeons meticulously excise tumours, employing precise manoeuvres to spare healthy tissues. TEM aims to remove the cancerous growth while minimising the impact on the surrounding unaffected areas within the rectum.

d) Laparoscopic and Robotic-Assisted Surgery

These minimally invasive techniques of surgery revolutionise rectal cancer treatment with their minimally invasive nature. Employing smaller incisions, specialised instruments, and advanced camera systems, these techniques facilitate intricate surgeries with heightened precision. The use of robotics enhances surgical dexterity, enabling complex manoeuvres. This approach significantly reduces surgical trauma, leading to swifter recovery periods and decreased patient postoperative discomfort. The smaller incisions and advanced technology minimise tissue damage, resulting in improved outcomes and offering a more favourable experience compared to traditional open surgeries for rectal cancer.

Dr. Deep Goel explains, “Robotic-assisted surgery is revolutionising how we approach rectal cancer. It offers unmatched precision and significantly reduces recovery time. For eligible patients, it’s the future of rectal cancer surgery.

e) Pelvic Exenteration

Pelvic exenteration, a procedure reserved for advanced cases of extensive rectal cancer spread, necessitates the removal of the rectum and adjacent organs like the bladder, prostate, or uterus. This intricate surgery aims to eradicate cancer that has aggressively disseminated within the pelvis. To restore waste elimination, surgeons create alternative pathways, such as constructing a colostomy or urostomy, allowing bodily functions to continue despite the organ removals.

A patient of Dr. Deep Goel shared, “When I was diagnosed with rectal cancer, I feared the worst. But Dr. Goel and his team recommended robotic surgery. I was walking the next day, and back to work in three weeks. I never imagined such a smooth recovery.”

Another patient shared, “My rectal cancer diagnosis was stressful, but coming to India was the turning point. Dr. Goel took the time to explain every surgical option. I underwent laparoscopic surgery, and the recovery was far better than I expected. Today, I’m cancer-free and living a normal life with my family. I’m grateful for the expert care I received.”

Moving Beyond the Diagnosis

Rectal cancer surgery involves a spectrum of treatment options, tailored to individual cases. The goal is to eradicate cancer while preserving function and quality of life. Patients benefit from more personalised and effective treatment options as surgical techniques evolve.

While surgical interventions are crucial, a multidisciplinary approach involving oncologists, surgeons, nurses, and allied health professionals is essential in providing comprehensive care. Furthermore, raising awareness about screening, early detection, and access to quality healthcare services globally remains pivotal in reducing the burden of rectal cancer.

Empowering individuals with different rectal cancer surgery options fosters informed decision-making and enhances patient-doctor communication, ultimately contributing to better outcomes and improved overall well-being.

FAQs

1. Will I experience pain after rectal cancer surgery?

Yes, some pain is expected, but it is well-managed with medications and usually improves within days to weeks.

2. Can rectal cancer surgery affect sexual function?

Yes, especially in surgeries involving nerves in the pelvic area, but many patients recover function over time with support.

3. How long will I stay in the hospital after surgery?

Typically, 3–7 days, depending on the type of surgery and how quickly you recover.

4. Will I need a colostomy bag permanently?

Not always. In many cases, if needed, the colostomy is temporary and reversed after healing.

5. How often will I need follow-up after surgery?

Usually every 3–6 months for the first few years to monitor for recurrence and manage any side effects.
