Minimally Invasive Surgery Laparoscopy Endoscopy Percutaneous surgery ESWL

Extracorporal Shockwave Lithotripsy (ESWL) ‘ A thousand grains of sand pass through the eye of a needle before a single pebble’ W. Spencer

ESWL Initially developed by aviation company, Dornier Shock waves generated by a spark Transmitted via water Energy absorbed by acoustic surface (stone) Stone shatters and fragments drained by urine

Laparoscopic Prostatectomy Largest experience in Singapore Follow up of 3 years More than 30 cases (3 in GEH)

Largest experience in Singapore

Follow up of 3 years

More than 30 cases (3 in GEH)

Laparoscopic prostatectomy v/s robotic prostatectomy Assistance from robot in suturing 3D view High capital and recurring cost

Assistance from robot in suturing

3D view

High capital and recurring cost

Tactile feed back Technically more demanding – training and experience critical Extraperitoneal, avoiding contact with intestine Allows for dissection of lymph nodes if necessary Lower cost (by at least $10K) Laparoscopic prostatectomy v/s robotic prostatectomy

Tactile feed back

Technically more demanding – training and experience critical

Extraperitoneal, avoiding contact with intestine

Allows for dissection of lymph nodes if necessary

Lower cost (by at least $10K)

Summary Surgery is moving towards minimally invasive ESWL, endoscopy, percutaneous & laparoscopy More than one or a combination of MIS modalities may be used
