Dr.Praveen performs laparoscopic and robotic surgeries for these cancers.
- Esophagus cancer
- Stomach cancer
- Colon cancer
- Rectal cancer
- Kidney tumor
- Endometrial cancer
- Cervical cancer
- Mediastinal tumors
How are these surgeries performed? How are they different from open surgeries?
Both laparoscopic and robotic cancer surgeries are collectively termed as minimal access surgery which means using much smaller incisions compared to open surgeries performed for cancer. To achieve an oncologically safe removal of cancer affected organs along with its draining lymph nodes an open cancer surgery requires relatively large surgical incisions compared to open surgeries done for non cancer related diseases. Such large incisions incite a reaction from the body’s protective mechanisms which leads to greater degrees of inflammation in the tissues. Along with it, a greater amount of pain. Both combined together affect patients breathing, mobility, requirement of pain medications, gut mobility etc. Contrary to this , both laparoscopic and robotic cancer surgery use 4-6 small incisions ( varying from 5mm to 12mm each). These incisions are strategically placed in different quadrants of the abdomen or chest wall so that the affected organ can be removed adhering to oncological principles.

If such small incisions are used, how is the cancer affected organ taken out?
To facilitate the extraction of the affected organ a small incision measuring 6-8cm is used. Most of these incisions are away from the midline of the body and division of muscles is usually avoided. Hence these specimen extraction incisions rarely add to the pain significantly.
In laparoscopic and robotic gynecological/colorectal surgeries the specimen(resected organ) can be extracted either through the vaginal opening or through the anal opening. This is called Natural Orifice Specimen Extraction ( NOSE). This method avoids additional incision on the abdomen.
Why are robotic and laparoscopic surgeries necessary in cancer treatment?
It has been proven time and again that minimal access surgery leads to lesser blood loss, less pain, early recovery, earlier return of bowel functions, better post operative rehabilitation. All these advantages translate into shorter hospital stay and reduced treatment costs.
Almost all cancer patients require multimodality treatment.i.e. combination of surgery, radiation and chemotherapy. And each one of this has to be incorporated into treatment planning in a timely manner to gain the maximum benefit out of it. In this context an early recovery provided by minimal access surgery is a great benefit to the patients.
Can all cancer surgeries be performed by laparoscopic and robotic surgery?
Regardless of the method used ( open or laparoscopic or robotic ) a cancer surgery has to respect the oncological principles of surgery.
Oncological principle means-
- Complete removal of the tumor with a margin of healthy tissue so that not just the tumour that is visible on the scans and to naked eye but also the possible microscopic cancer deposit and cells that may be present in the surrounding normal looking tissue are removed. How much of a healthy tissue margin is to be removed varies depending on the organ that is affected by the cancer.
- The lymph nodes that drain the cancer affected organ also have to be removed during the surgery.
- Spillage of cancer tissue or cells into other areas is to be avoided at all costs.
- Technically any method of surgery that respects these principles and can achieve a successful surgery, should be acceptable.
However, only in those organs and cancer stages where laparoscopic and robotic cancer surgeries have been studied and proven to be safe, is using these modalities recommended by national and international organizations of surgical oncology.
As a general rule only early stage cancers and cancers that are still within the confines of affected organs with limited spread to the surrounding nodes are ideal candidates for laparoscopic and robotic surgery.

- Cancer of uterus ( endometrium)
- Cancer of the cervix
- Cancer of kidney
- Mediastinal tumours
- Thymic Tumours
