Single Port Laparoscopic surgery (key-hole minimally invasive surgery)
Can benefit patients by having less wound pain, less wound infection and faster recovery.
With further advances in surgical technique and instrumentation, further reduction in surgical trauma can now be achieved by using only a single key-hole instead of multiple key-holes in some of the abdominal surgeries.
Dr Stephen Chang is pioneer in this technique of single key-hole minimally invasive surgery with more than 500 case experience (one of the largest in the region and internationally).
He has published widely in this area and is actively promoting it through international forum.
