Single Site Umbilical Laparoscopic Surgery (SSULS) George W. Holcomb, III, M.D., MBA Surgeon-in-Chief Children’s Mercy Hospital Kansas City, MO
2
Open Surgery Laparoscopic Surgery 1)Less discomfort 2)Reduced hospitalization 3)Faster return to routine activities 4)Cosmesis

7
What Else Is Different? Instruments are in-line and parallel to each other Ideally, instruments/telescope should be different lengths
8
What Else Is Different? Assistant/camera holder stands next to or behind the surgeon
9
What Else Is Different? Harder to operate
10
What Operations Are Being Done Using This SSULS Approach? Appendectomy Cholecystectomy Splenectomy Ileocecectomy Pyloromyotomy (CH-A) Fundoplication (CH-A) Others

22
Conclusion These series show that single site surgery is feasible, and appears to be associated with acceptable operating times
23
Disadvantages Compromised degrees of freedom and triangulation Visualization limited by inline field of view and motion of instruments More difficult for the surgeon
24
Questions Do the benefits outweigh the risks? What are the benefits? Is there improved cosmesis? Prospective evidence needed We are enrolling in 3 SSULS PRT’s Appendectomy, Cholecystectomy, Splenectomy Validated scar assessment tool

Conclusions Obesity increases operating time, postoperative length of stay, doses of narcotics, and hospital charges c/w single site lap appendectomy Obesity has no impact in 3 port appendectomy Clinically significant increase in wound infection in overweight and obese patient undergoing single site lap appendectomy We do not recommend single site laparoscopic appendectomy in obese patients IPEG 2012
