Minimally invasive surgery (MIS) has transformed the medical field by providing a less traumatic alternative to traditional open surgeries. These advanced techniques involve making small incisions, often less than an inch long, to access the treatment area. Surgeons then insert specialised instruments and a tiny camera to perform the procedure while monitoring progress on a screen.

Types of MIS

There are several types of minimally invasive procedures, including:

Laparoscopic surgery: This involves making small incisions in the abdomen and inserting a tiny camera (laparoscope) and surgical instruments to perform procedures like gallbladder removal, hernia repair, and gynaecological surgeries.
Endovascular surgery: It treats issues affecting blood vessels, such as aneurysms. It involves inserting grafts through the arteries and placing them inside the aorta to seal off the aneurysm.
Bariatric Surgery: Also known as weight loss surgery, it is used to treat obesity and related conditions like diabetes, sleep apnea. Procedures include gastric bypass and gastric sleeve surgery.
Video-Assisted Thoracoscopic Surgery (VATS): It is used to diagnose and treat conditions in the chest, such as lung cancer, oesophageal disorders, and excessive sweating. It involves making small incisions and inserting a thoracoscope with a camera.
Hysteroscopic surgery: Performed using a hysteroscope inserted through the cervix to inspect the uterine cavity and treat conditions like fibroids, polyps, and abnormal bleeding.
Vaginal surgery: Also known as Vaginal Access Minimally Invasive Surgery (VAMIS), it uses the vaginal opening to access pelvic organs and perform procedures like hysterectomy and fibroid removal without abdominal incisions.
Robotic surgery: It is similar to laparoscopic surgery but uses advanced robotic technology to provide greater precision, control, and flexibility for complex procedures.

Benefits of MIS

Minimally invasive procedures offer several benefits compared to traditional open surgery methods, as highlighted in the sources provided:

Reduced Pain and Blood Loss: Minimally invasive surgery techniques, such as robot-assisted surgery, result in significantly less pain and blood loss than conventional surgical approaches. The precise movements and smaller incisions lead to less trauma and reduce patient pain.
Faster Recovery: Minimally invasive surgery allows for speedier recovery times due to less tissue trauma and smaller incisions. This results in quicker healing and reduced chances of complications like infections, blood clots, and excessive bleeding, leading to a more rapid return to normal activities.
Shorter Hospital Stays: Patients undergoing minimally invasive procedures often experience shorter hospital stays, with some being able to leave the hospital the next day or even the same day as the procedure. This shorter hospitalisation period contributes to a faster recovery and a quicker return to daily life.
Precision and Better Outcomes: Techniques like robot-assisted surgery provide surgeons with highly detailed 3-D images for superior visualisation, allowing for precise removal and repair. This precision is crucial, especially in procedures like tumour patient outcomes node dissection, ensuring better outcomes for patients.
Lower Risk of Complications: Minimally invasive surgery reduces the risk of postoperative major complications, infections, and stress on the immune system. It also decreases the chances of surgical site infections, which are a common reason for patient readmission to the hospital after surgery.
Smaller Scars: Minimally invasive procedures result in smaller and barely noticeable scars compared to traditional open surgeries. The smaller incisions not only lead to reduced scarring but also minimise the risk of problems like herniation during the healing process.

What happens during MIS?

During a minimally invasive surgery (MIS) procedure, the surgeon makes small incisions, often less than an inch long, to access the treatment area. The surgeon then inserts specialized instruments and a tiny camera, called a laparoscope, to perform the surgery while monitoring progress on a screen.

The key steps involved in a minimally invasive surgery are:

Small incisions: The surgeon makes several small incisions near the treatment, typically less than the treatment area.
Insertion of iTo access the treatment area, specialised surgical instruments and a tiny camera (laparoscope) are inserted through the treatment area.
Inflation of the treatment area: Carbon dioxide gas may be used to expand the treatment area for better visibility and access.
Visualization: The laparoscope transmits images of the internal structures to a monitor, allowing the surgeon to view the treatment area and guide the instruments.
Surgical procedure: The surgeon performs the necessary surgical procedure, such as removing tissue or repairing damaged structures, while monitoring the progress on the screen.
Closure: After the procedure is completed, the instruments are removed, and the small incisions are closed with sutures or surgical glue.

Minimally invasive procedures offer numerous benefits over traditional open surgeries, including smaller incisions, reduced pain, and faster recovery times. As surgical techniques continue to advance, MIS is becoming an increasingly common and effective option for treating a variety of medical conditions.
