FAQ- Robotic Surgery for Colorectal Cancer & Appendix
 
Robotic Surgery Using The Da Vince System For Rectal Cancers
 
 
Traditional open surgery for colorectal cancer requires a long incision and leaves behind a painful and unsightly scar. The longer incision leads to more pain after surgery and mobility tends to be slower. A longer wound also has a higher chance of developing infections and wound-related complications. Because the bowel is manipulated by the hand during open surgery, it takes longer for the bowel to recover its digestive function after open surgery, leading to a longer hospital stay.

Laparoscopic (key-hole) surgery is a minimally invasive technique that allows the safe resection of the cancer via a few small incisions of 1-2cm (i.e. ‘key-holes). This reduced the degree of pain and also avoids the need for a long incision or scar. However, Laparoscopic surgery employs the use of straight instruments in place of the hand which are inserted into the abdominal cavity via these ‘key-holes’. A camera (laparoscope) that is inserted into one of the ‘key-holes’ allows the surgeon to visualize the surgery in 2-D views on a HD screen. However, because the instruments are straight and rigid unlike the wrists of our hands, surgical dissections within the pelvis can be challenging.

The next frontier in minimally invasive surgery is the da Vinci Surgical Robotic System which combined the advantages of the laparoscopic access through a few small ‘key-holes’ but has the additional advantage of 3-D high-definition visualization giving the surgeon unparalleled depth perception and special robotic instruments which allow for wrist-like movements within the narrow confines of the pelvis. By overcoming the challenges of traditional open and laparoscopic surgery, da Vinci takes colorectal cancer surgery to a whole new level, beyond the limits of the human hand.

Using The Da Vinci Surgical Robot For Resection Of Rectal Cancers Patients Many Potential Benefits, Including:
 
  1. More precise and meticulous dissection in the narrow pelvic cavity
  2. Faster recovery of bowel function and return to diet after surgery
  3. Less blood loss from a more meticulous dissection
  4. Shorter hospital stay compared to conventional open surgery
  5. Fast recovery time and less pain after surgery
