The Advantages Of Robotic & Laparoscopic Rectal Cancer Surgery Include

What Is Rectal Cancer?

When the cells lining the rectum begin to divide and grow uncontrollably, rectal cancer develops. It grows at the end of the large intestine (the colon). The rectum connects to the anus. Rectal cancer usually develops as a polyp (a benign clump of cells) that progresses to malignancy.

Now, let’s look at the Causes and Risks of Rectal Cancer

The exact cause of rectal cancer is unknown. However, the risk of having the disease rises with age. People with a family history of colorectal cancer or specific genetic cancer syndromes are more likely to get the disease. Other known rectal cancer risk factors include:

  • Diet
  • Smoking
  • Alcohol use
  • Sedentary lifestyle
  • Obesity
  • Diabetes

What are the Symptoms of Rectal Cancer?

The following are some of the most common rectal cancer signs and symptoms:

  • changes in bowel habits
  • constipation
  • diarrhoea
  • blood in the stool, either bright red or very dark
  • stools with a narrower width than typical
  • consistent gas pains, bloating, fullness, or cramps
  • weight loss for no known reason
  • constant exhaustion
  • vomiting

Diagnosis of Rectal Cancer

Dr. Sandeep Nayak, a seasoned oncologist in Bangalore, may order tests to confirm your diagnosis if he suspects you have rectal cancer. These tests may include:

  • Colonoscopy:It involves using a long tube with a tiny camera to inspect the inside of your colon and rectum.
  • Biopsy:It entails removing a small sample of the suspicious tissue and sending it to the lab for investigation.
  • Imaging Tests:The doctor may recommend imaging tests like chest X-rays and CT scans if they suspect metastases in the abdomen or pelvis.
  • PET (positron emission tomography) scan: Your doctor may ask you to swallow a specific dye containing radioactive tracers before undergoing a PET scan. The dye may be injected or breathed in some cases. The dye highlights the diseased areas.

Rectal Cancer Treatment

Surgery is the most common treatment for rectal cancer at all stages, though it is frequently combined with radiation, chemotherapy, or both.

A. Surgery

Dr. Sandeep Nayak, a highly-qualified and experienced surgical oncologist in Bangalore, may execute advanced rectal cancer surgery procedures, including sphincter preservation to remove difficult-to-treat tumors.

The surgeon can remove cancer while preserving healthy tissue using laparoscopic and robotic techniques, allowing you to keep normal bowel function.

Your doctor will remove your cancer using one of the following procedures, depending on the location, stage, and size of your tumor:

1. Abdomino-Perineal Resection (APR):

It is the standard surgery for back passage (rectum) malignancies. This implies that the rectum (back passage) and anus (back passage opening) are removed in conjunction with the creation of a permanent colostomy (a bag on the abdominal wall that collects waste). We can avoid permanent colostomy using these advanced procedures and technologies.

3. Anterior resection, also known as low anterior resection:

It is a surgical procedure that removes tumours from the back passage away from the anal muscles (sphincter) that controls the anus. The patient’s intestines and back passage are connected so that patient can pass stool through the back passage. Using minimally invasive procedures, MACS makes this major procedure less painful and manageable for rectal cancer patients.

2. Preventing a permanent colostomy and maintaining a normal lifestyle: 

The loss of the anus and the requirement for a permanent stoma are the most common concerns of patients with rectal cancer. This alters one’s identity. The way you live your life changes once you get a colostomy.

Fortunately, utilizing advanced methods such as intersphincteric dissection and ultra-low anterior dissection with colo-anal anastomosis, we can retain the anus and restore normalcy for many rectal cancer patients. The use of robotics improves the outcomes of these surgeries compared to other conventional methods.

B. Chemotherapy

It can be used to shrink a tumor before surgery or to eradicate any cancer cells afterward.

C. Radiation therapy

This therapy uses intense, tailored energy beams to treat cancer while preserving healthy tissue accurately.

D. Immunotherapy

It involves administering drugs that boost your immunity and make your immune system capable of fighting cancer cells.

E. Targeted drug therapy

These drugs target cancer cells‘ particular changes that allow them to grow and spread.

Prevention of Rectal Cancer

Although one cannot prevent rectal cancer completely, there are a few things you may do to minimize your risk:

  • Avoid eating red, processed meat regularly.
  • Keep a healthy weight.
  • Give up smoking.
  • Avoid drinking too much alcohol.
  • Maintain an active life.

What is the long-term outlook on rectal cancer?

Rectal cancer can be successfully treated in many cases. Over the last few decades, advancements in medical technology have improved the overall outlook for patients with rectal cancer. Other factors that can affect your prognosis if you have rectal cancer include:

  • where cancer may have spread.
  • whether or not your bowel is obstructed.
  • whether complete tumor removal is possible.
  • age and overall well-being.
  • whether it is a recurrence.
  • how well you can tolerate rectal cancer treatment.

Your doctor is the best source of information when it comes to your prognosis.

Staging & Treatment of Rectal Cancer

The stage of rectal cancer can only be confirmed after surgical removal of tumor. However, imaging studies like CT scan or MRI scan give good idea about the stage of the disease in many cases.

Surgery is the main treatment of rectal cancer. All the rectal cancer surgeries can be done robotically or laparoscopically with great advantage to the patient.

colon cancer stages

Stage 0

Stage 0 rectal cancer is when the disease is limited to the innermost lining (mucosa). While performing endoscopy, an endoscopist can exise it completely (polypectomy). When performed properly, this would serve as complete treatment. However, often more extensive surgery (resection) to remove rectal cancers is required (discribed in next session). Surgery can cure cancer at this stage.

Stage I

Stage I rectal tumors are the ones that have spread beyond the inner lining (mucosa) to the second and third layers. The cancer has not spread outside the colon. Standard treatment involves surgery to remove the cancer (described in next session). Additional treatments like chemotherapy and radiotherapy are not usually needed. Aggressive surgery has the potential to cure this cancer. The five-year survival rate for this stage is more than 90%

Stage II

Stage II rectal cancers are larger and extend through the muscular wall and may have invaded other organs, like the bladder, uterus, or prostate gland. However, there is no cancer in the lymph nodes (small nodular structures that are present throughout the body that clear the tissue fluids). Standard treatment is surgical removal of the cancer (described in next session). When this stage is detected before surgery by CT scan or MRI scan, radiation therapy along with chemotherapy (5FU or Capacitabine) is given for better long term results. If not, the same may be given after surgery. The five-year survival rate for stage II is 78%

Stage III

Stage III rectal cancers have spread outside the rectal wall to the lymph nodes (small nodular structures that are present throughout the body that clear the tissue fluids). Lymph nodes are one of the first to get affected by spreading cancer. The treatment involves multiple modalities:

  • Surgery to remove the tumor and all involved lymph nodes (described in next session).
  • Radiation with or without chemotherapy has to be given before or after surgery (your oncologist will decide about the timing). When given before, this may help in reduction of size of the tumor and preservation of anus (Avoiding permanent colostomy and feel normal).

The five-year survival rate for stage III rectal cancer is about 64%

Stage IV

Stage IV rectal cancers are the ones that have spread to far away organs. Usually these include liver or lung. The mainstay of treatment is chemotherapy, but surgery to remove the tumor may also be recommended. Surgery, when performed, is often used to relieve or prevent blockage of the rectum or to prevent rectal bleeding. A curative surgery may be considered in selected cases where all the tumor tissue can be surgically removed (limited number of liver & lung spread). When surgery is possible, the five-year survival rate can be upto 50%.

When surgery is not possible, other options include destroying them with microwaves or heat (radiofrequency ablation) or giving chemotherapy directly into the liver used with embolization (chemoembolization), etc.

Surgeries For Rectal Cancer

The only treatment that can sure rectal cancer is surgery. All other forms of treatment like chemotherapy and radiotherapy can only reduce risk of recurrence of cancer after surgery, but cannot cure the cancer. A number of different surgical procedures are available to treat tumours of the back passage, the choice depending on where the tumour is located:

1. Abdomino-Perineal Resection (APR)

It is the standard surgery performed for cancers of back passage (rectum). This means an operation to remove the rectum (back passage) and anus (opening to the back passage) are removed with creation of a permanent colostomy (a bag on the abdominal wall collect waste). With present day technique and technology, we can avoid permanent colostomy same cure rates.

2. Avoiding permanent colostomy and feel normal:

The greatest fear of patients suffuring from rectal cancers is loss of anus and the need to have a permanent stoma. This changes the self image. Colostomy changes the way you lead your life. Luckily today for many rectal cancer sufferers we are able to save the anus and restore normalcy by using specialized techniques called intersphincteric dissection and ultra low anterior dissection  with colo-anal anastomosis. These surgeries are performed with better results using robotics than with other approaches.

3. Anterior Resection or Low Anterior Resection:

This surgery is used for those tumours of the back passage, that are away from the anal muscles (sphincter) those control the anus. The bowel and the back passage are joined together so that the patient can pass motion though the back passage. MACS makes this major surgery less painful and tolerable for the patients (see advantages listed above)
