MIS vs Conventional Surgery

What is right for me?

by Dr Shehab

Surgery is a scary procedure for anyone to go through – period! If you would prefer to stay at home than be on an operating table, you’re not alone! But wait – there’s good news! Dr Shehab from KPJ Kuching discusses Minimally Invasive Surgery!


What is Minimally Invasive Surgery (MIS)?
To many people, ‘minimally invasive’ means a specific procedure or surgery. It is in fact a concept or a broader medical philosophy that is adopted when doing surgery or a procedure – to operate through less destructive incisions, affect normal tissue as little as possible, and use state-of-art tools and instruments that allow us to perform the procedure safely

What is the difference between Minimally Invasive Surgery and conventional surgery?
In conventional surgery, good exposure to the surgical field is key to safe and successful operation and thus larger surgical incisions are inevitable. In minimally invasive surgery, exposure is still essential but can now be provided through tiny incisions. This means quicker recovery, shorter hospital stays and less pain.

Is Minimally Invasive Surgery and Laparoscopic Surgery the same?
This term is generally used interchangeably with minimal access, laparoscopic and keyhole surgery. Specifically, laparoscopic surgery refers to performing of surgery in the abdominal cavity using the “minimally invasive” concept.

How does Minimally Invasive Surgery work?
Several small incisions are made and thin tubes (trocars) are inserted into abdomen. Carbon dioxide gas is insufflated into the abdominal cavity, creating a working and viewing space between the internal organs and the skin. Through these trocars, long, thin specialised instruments and miniature camera (laparoscope) are placed to perform surgery. The thin laparoscopic camera provides the light and visualisation with which the surgeon and the surgical team see the magnified operative field on highdefinition screens. This enables precise and safe dissection. Using high-tech instruments, the surgeon performs the same operation as conventional “open” surgery with equivalent long-term outcomes but with smaller incisions and other potential benefits in the early post-surgery recovery period

What are the potential benefits of Minimally Invasive Surgery?
It offers both clinical and economic benefits. From a clinical perspective, MIS is associated with improved outcomes through reduced rates of complications such as infections, blood loss, incisional hernias, adhesions, and postoperative pain. Economic benefits include reduced length of hospital stay and readmissions, decreased recovery times, and lower costs across the episode of care. After hospital discharge, MIS patients typically are back to their daily routines faster than those who have had open surgery.

What kinds of operations can be performed using Laparoscopic Surgery?
Most of the abdominal and intestinal surgeries can be performed using the laparoscopic technique. Procedures such as hernia repairs, gastric resection/bypass, bowel resection, and organ removal are now routinely carried out laparoscopically.

Laparoscopic surgery has successfully replaced open surgery as the preferred treatment option for issues such as colorectal surgery, bariatric surgery and gallbladder removal.

Am I a candidate for a Minimally Invasive Surgery?
MIS isn’t for everyone and not all procedures can (or should) be done through minimally invasive methods. Sometimes conventional open surgery provides surgeons better access to the area to be treated, and sometimes a patient’s age, physical condition, medical and surgical history may necessitate open surgery.

In some cases, a patient might be scheduled for a minimally invasive procedure, but after getting a view inside the body the surgeon might have to “convert” the procedure to an open (conventional) surgery. This may be because the problem or the anatomy is different from what the surgeon expected.

Continual innovations in minimally invasive surgery make it beneficial for people with a wide range of conditions. If you need surgery and think you may be a candidate for this approach, talk with your doctor. Only your doctor can determine if a minimally invasive surgery is right for you.
