9 Challenges of Laparoscopic Colorectal Surgery  Multiple Quadrants  Multiple Vessels  Small Bowel Positioning  Bowel Transection  Bowel Anastomosis

10 Challenges of Laparoscopic Colorectal Surgery  Time Consuming  Technically Challenging  Technical Ability  Advanced Technology  Capable Assistants

11 Strategy to Combat Time Constraints of Laparoscopic Colorectal Surgery  break operation into directly productive vs. nonproductive actions  standardize  standardize approach to improve efficiency gravity  retraction performed by gravity  keep repositioning to a minimum 3 Trocar Technique

12 SILS Colectomy  Advantages simplified method need only a camera operator safe and efficient reproducible

13 “Problems” with M.I.S.

14 “Problems” with M.I.S.  Problems with SILS

15 Laparoscopic CRS  Improved cosmesis  Decreased pain  Decreased recovery

16 “Problems” with M.I.S.  Decreased ability to complain of pain Improvement in maximum pain score on POD1 & POD2 (p<0.05) Shorter LOS Papaconstantinou & Thomas SILS

17 “Problems” with M.I.S.  Decreased ability to complain of pain  Inability to “show off” a big scar SILSSILS

18 “Problems” with M.I.S.  Decreased ability to complain of pain  Inability to “show off” a big scar SILSSILS

19 “Problems” with M.I.S.  Decreased ability to complain of pain  Inability to “show off” a big scar  Having to return to work earlier

21 Laparoscopic Colectomy  Less blood loss  Quicker recovery to normal function  Better margins of resection  Better visualization Mesorectal excision Decrease incidence of autonomic nerve injury More precise surgical procedure  Less wound related problems Infection Dehiscence Incisional hernia  Minimally invasive procedure Advantages

22 SILS Colorectal Surgery

23 SILS Colectomy  N = 99  Age = 9 – 93  30 with previous abdominal operations  BMI = 26 (15 – 39)

24 SILS Colectomy  N = 99 Diagnosis  UC: 46Neoplasia: 17  Crohn’s: 10Diverticulitis: 10  FAP: 2Other: 14

25 SILS Colectomy N = 99  OR Time:105 minutes (13 – 245)  Incision Length:3.7 cm (1.2 – 7.8)  LN Harvest*:44

26 SILS Colectomy N = 99 Ports  87SILS  12Additional Ports 1:9 2:1 3:2

27 Complications? Wound Complications  Infections Similar Easy to deal with  Hernias? Too early to tell Access technique?

28 Hernia  Variable rates of occurrence  Dependent on location  Avoidable?  Tissue necrosis?

29 Hernia  Variable rates of occurrence  Dependent on location  Avoidable?  Tissue necrosis?  WE DON’T KNOW!!!!!

30 Difficulties?  5 mm endoeye  SKILLED camera operator  Camera, then instruments Not both at the same time  Splenic flexure

31 Difficulties? Port  SILS (Covidien) Atraumatic Simplistic Easy to use  Triport, Ethicon, Gelpoint

32 SILS Colorectal  Benefits over conventional laparoscopy  Drawbacks over conventional laparoscopy  Incidence of hernia formation?

33 Summary Single port laparoscopy in colorectal surgery  Minimize abdominal trauma  May utilize a natural body orifice or scar such as the Umbilicus  Potential decrease in morbidity  Certainly superior cosmesis  “NOTES” Natural Orifice Transluminal Endoscopic Surgery”……..experimental  SPL seems to be a practical clinical step towards NOTES
