Minimal Invasive Surgery is exactly what the name implies: a surgery where smallest or lease amount of incisions are made. In most cases, an incision of a few millimeters long is made, and a laparoscope is inserted into the the body, allowing the surgeon a full view of his work site.


The first recorded surgery of this kind was in 1988. A gall bladder was removed by Dr. J. Barry McKernan. He made a 10-millimeter incision on a patient’s abdomen and inserted a small tubular camera into it.


This method benefits everyone. For the surgeon, it’s not bloody mess. There is very little bleeding, and he/she only has to manage a small patch. It also saves a lot of time, since the incision is made and stitched up in a comparatively smaller amount of time. And even with its higher accuracy rate, if a surgeon fails to succeed via minimal invasive surgery, it is very easy to switch to open surgery.

Advantages for the patient are numerous. There is less tissue damage, so less scarring occurs. There is less pain. Small amount of blood is lost. Recovery is quicker. The stay in the hospital is shorter, which means the patients resume their daily lives quicker. And the chances being infected are very low as well. Also, it is quite cheaper than open surgery.

Robotic and Non-Robotic Method

Minimal invasive surgery is done can be done by the robotic method or the non-robotic method. The robotic method includes a four-armed device, which is connected to a console with two sets of master controllers, operated by surgeons. With the help of a laparoscope, surgeons are able to see inside the incision and the arms mimic the movement of the surgeon’s hands with extreme precision.

The non-robotic method is also in practice. In this method, the surgeon inserts video camera, attached to a thin tube, through a small incision, or through natural orifices of the body, to get an inside view, and then insert tiny surgical instruments, which may not have the pinpointed accuracy of the robotic method, but is still considered a better option than open surgery.

Diseases Treated

A number of disease are treated by this method. Several cancers of the liver, lungs, pancreas, ovaries and kidneys have been successfully treated. Also, pancreatic lesions, gastroeasophagal reflux disease and treatments for obesity have been done the same way. Orophyrangeal cancer and thyroid cancer are also treated by minimal incision method. A number of kidney disorders, including kidney cysts, stones and deposits have been removed. It also helps in kidney removal. Prostate cancer and vaginal prolapse have also been treated with a similar method. In the heart, mitral valve prolapse has been treated with this method. Also, atrial septal defect and atrial defibrillation has also been treated. Neurological disorders, which include spine disorders, lumbar and cervical disc hernias and anterior and posterior cranial fossa tumors have been cured too.


To conclude, minimal invasive surgery is not only easier and safer, but has proven its efficiency time and time again. So, it is definitely recommended.
