Minimally Invasive Surgery (MIS) has become a very common procedure in hospitals all over the world. In this surgery, the surgeons make a tiny incision instead of a very large one that is common in the traditional open surgeries; and use several different techniques due to which the body is injured less. As these incisions are small, the patients tend to recover faster, there is less scarring, and the pain is also minimal.
It is typically performed on an outpatient basis, or the patient needs to stay in the hospital for a short period of time.
During this procedure, the surgeon makes small incisions of just ¾ inch in the skin through which special instruments and a camera are passed.
The doctor uses these instruments to perform the operation by monitoring the proceedings with the images displayed by the camera on the computer.
The alternate names for minimally invasive surgery are:
- Laparoscopy surgery
- Keyhole surgery
- Bandaid surgery
What is the difference between Robotic Surgery/Minimally invasive surgery and Open Surgery?
There are several differences between Robotic Surgery/ Minimally Invasive Surgery (MIS) and Open Surgery. They are:
- Minimally Invasive Surgery is performed through tiny incisions made by doctors, whereas open surgery is done by making a large opening.
- Patients suffer fewer traumas in MIS than in open surgery.
- Patients of MIS need less time to recover and can resume work in a short span of time, whereas the patients of open surgery need more time to recover.
- The blood loss during MIS is much less than that in an Open Surgery.
- There is less scarring in MIS as compared to Open Surgery.
Which procedures have been performed using Robotic Surgery?
There are several procedures that are performed using this form of surgery. They are:
General Surgery – Several general surgeries like benign pancreatic lesions, pancreatic cancer, hernias, liver tumours (malignant and benign), obesity (bariatric surgery, gastric bypass, gastric banding), severe GERD (gastroesophageal reflux disease), and many more are performed using this procedure.
Lung – Esophageal cancer, lung tumour, and other diseases are treated with this surgery.
Gynaecologic - It is one of the popular fields where Robotic Surgery is performed. This surgery is done for gynaecologic cancer, endometriosis, benign tumours, benign cervical disorders, staging of lymph nodes, removal of ovaries, ovarian cysts, and much more.
Urological – This surgery is widely used for kidney cysts, Kidney disorders, kidney blockage, kidney stones, prostate cancer, vaginal prolapsed, and other urological diseases.
Head and Neck – The MIS is done for complex surgeries of head and neck diseases like thyroid cancer and oropharyngeal cancer (head and neck cancer).
Heart: Several heart conditions like atrial septal defects,mitral valve repair and prolapse, and atrial fibrillation are also performed using this procedure.
What are Robotic Surgery benefits to patients compared with open surgery?
Robotic Surgery has a lot of benefits as compared with Open Surgery:
- Patients get few cuts in this surgery as compared to the open surgery. Due to this they feel less discomfort and pain, and recover way faster.
- In this surgery the patient has to rest for a very short time and they can resume their daily activities within a week or two; whereas after an Open surgery, the patient needs to rest for at least a month.
- In this surgery, the patient does not need to stay in hospital for a long time. The patient is typically admitted on an outpatient basis or he/she has to stay in the hospital for a short while. But in an Open surgery the patient needs to be admitted in the hospital for a long time.
- The amount of blood loss is much less in this surgery than in an Open one.
- Since only small incisions are made in this surgery, the amount of scarring is much less than in a traditional one.
Robotic Surgery is very expensive right now. It costs approximately Rs. 50,000 to Rs. 75,000 more than a Traditional or Open Surgery does. This is due to the costly robotic equipment that is used to carry out the surgery.
