Minimal access surgery

What is minimal access surgery?

Minimal access / laparoscopic / keyhole surgery involves the surgeon making multiple small incisions (5-12mm in size) rather than one large incision. Dr Cooper will place special tubes called "access ports" into the abdominal cavity, and carbon dioxide gas is used to inflate the abdomen and create a space to work in. A special telescope or lens is then introduced which transmits a magnified image from inside the abdominal cavity onto a monitor inside the theatre. While observing the monitor, the surgeon then performs the necessary procedure using a variety of specialized instruments that are passed through the ports as and when needed.

The introduction of minimal access surgery began in 1985 when laparoscopic cholecystectomy was first performed to remove a diseased gallbladder. The technique was initially met with scepticism and resistance because of the degree of difficulty, longer learning curves, higher initial procedural costs and loss of tactile sensation. When minimal access principles were applied to cancer procedures, there were also initial concerns regarding the adequacy of specimen resections and the theoretical risk of port site cancer recurrences. However, those initial misgivings have now all fallen by the wayside. Numerous randomized controlled trials have validated the effectiveness and safety of minimal access surgery, and the advantages are well documented:

Minimal access surgery is one of Dr Charl Cooper’s main areas of interest and expertise. His interest began as a surgical trainee at Tygerberg Hospital. After qualifying as a surgeon, he attended numerous local and international training courses and workshops and honed his skills as a consultant surgeon at Tygerberg where he was also in charge of the minimal access bariatric surgery (also known as weight loss surgery) programme. Dr Cooper’s enthusiasm for minimal access surgery was recognized in 2011 when he was awarded the SASES / Karl Storz Travelling Fellowship. In 2012 he spent 2 months in Straubing, Germany under the tutelage of prof Robert Obermaier and Dr Markus Walz. Here Dr Charl Cooper gained valuable exposure to ‘state of the art’ minimal access procedures which he has embraced and incorporated into his own practice.

Dr Charl Cooper can now offer the following laparoscopic/minimal access procedures:

Single-incision laparoscopic surgery (SILS):

SILS is a relatively new minimal access surgery where the whole procedure is performed using a single highly modified port placed via the umbilicus. The advantage is that scarring is virtually eliminated because the port is placed in the umbilicus. It is, however, technically much more challenging to perform and does require longer anaesthetic and theatre time.
