Minimally Invasive Surgery (MIS) commonly known as ‘keyhole surgery’ (laparoscopy or hysteroscopy) involves using small incision surgical techniques that are intended to achieve clinical outcomes akin to those of conventional open surgery but are associated with minimal discomfort, faster recovery time and shorter hospital stay.
MIS uses skilled surgical techniques and special equipment and instruments to successfully perform the surgery.
Compared to traditional open surgery, MIS has the following benefits for patients:
The Minimally Invasive Surgery is not suitable for all patients. It has certain limitations which include:
Laparoscopic surgery incorporates the use of a thin tube-like instrument typically known as a laparoscope attached to a light source to visualize the area of concern inside the abdomen or plevis.
A laparoscope is passed into the abdomen through a tiny incision (cut) in the skin. Laparoscopy is performed in order to determine the cause of abdominal/ pelvic pain or distention It can confirm or refute abnormal radiological findings (ultrasound scan, CT scans MRI, X-rays).
Laparoscopic surgery can successfully remove endometriosis, pelvic adhesions, fibroids, uterus ovarian cysts and ectopic pregnancies.
Laparoscopic surgery is performed under general anaesthesia. The skin over the abdomen is cleaned. The OBYGN then makes a incision (cut) about 1-2 cm long into the navel (belly button).
The abdomen is distended with CO2 gas. This allows the Obgyn to visualise the internal organs clearly with the laparoscope which is inserted through the incision into the abdominal cavity. The laparoscope is connected to a monitor to allow the gynaecologist and the rest of the surgical team to visualize and perform the entire operation.
Once the surgery is completed, the laparoscope and other instruments are removed. The incisions are closed and dressings are applied.
The recovery time varies depending on the type of surgery that was performed. The discomfort post-surgery is usually minimal when compared to open surgery.
In laparoscopic surgery, the risk of complications may increase, depending on the complexity of the operation performed.
In general, laparoscopic surgery is safe but as with all types of surgery, there are risk and complications involved.
