Abstract
Single port surgery (SPS) is an attempt to reduce damage to the abdominal wall by introducing the scope and instruments in a relatively small area. Less invasiveness of this approach comparing to the standard one is yet to be proven. Cosmetic superiority is obvious and the operative scar is almost invisible 2 weeks after SPS surgery. Another approach to reduce damage to the body wall is needlescopic surgery where the diameter of instruments is less than 3 mm. Researchers have noticed that pros and cons that SPS and needlescopic surgery pose are complimentary and mixed use of these technique ease the technical difficulty while keeping the excellent cosmetic outcome. This hybrid approach is collectively named reduced port surgery. NOTES device and surgical robot (DaVinci) has reportedly been used in reduced port surgery. Combined use of these tools with minimal damage to the body wall would be the future of minimally invasive surgery.
