  3. There are 4 basic techniques used to create pneumoperitoneum: • blind Veress needle • direct trocar insertion • optical trocar insertion • open laparoscopy Gu¨nenc et al. Surg Laparosc Endosc Percutan Tech, 2005

  4. In 578 laparoscopic procedures: • blind insertion of the Veress needle (group 1, n = 301) • direct trocar insertion with elevation of the rectus sheath using 2 towel clips (group 2, n = 277). Gu¨nenc et al. Surg Laparosc Endosc Percutan Tech, 2005

  5. Results: Total complication rates: • gr 1 = 15.7% (n = 33) • gr 2 = 3.3% (n = 4) (P < 0.05) Conclusion: Direct trocar insertion with elevation of the rectus sheath using 2 towel clips is an easy, safe, and effective technique. Gu¨nenc et al. Surg Laparosc Endosc Percutan Tech, 2005

  6. Having been a Veress needle advocate throughout my career, I am loath to change. However, this scientifically well-done study gives me “pause”; quicker pneumoperitoneum with fewer complications is certainly a compelling argument for considering a change. Ralph V. Clayman, J of urol. Pg 1847. Nov, 2005

  7. Telescopes from 1 mm diameter and 17.5 cm length up to 10 mm diameter and 42 cm length • Longer OR time • In preparing or starting • Visualization • Instruments

  8. Laparoscopic instruments

  9. This reusable three-piece: Available in, 5 mm and 10 mm sizes, with lengths of 20 cm, 30 cm, 36 cm and 43 cm.

  10. Clips & Staplers • Endo-GIA stapler • Clips • Hem-o-lock

  11. Entrapment bag • LapSac

  12. Entrapment bag • Endobag (Tyco)

  13. Instruments Summary • Optics should be the state of art. • Test function before use • Familiarize staff with troubleshooting • Think cost-effective

  14. Nephrectomy

  15. Flexible pyeloscopy for removal of caliceal stones using triradial graspers

  16. The renal pelvis is sewn to the corresponding corner of the ureter (EndoStitch device shown).

  17. Auto suturing • 6 surgeons with laparoscopic experience were trained on the three suturing techniques. • A pelvic trainer was set up with a freshly marked and incised swine renal pelvis and ureter • 216 knots • Knot was individually tested on a Monsanto Model 10 tensiometer (slippage, strength, and breakage points) Pattaras et al, J Endourol. 2001 Mar

  18. Auto suturing Pattaras et al, J Endourol. 2001 Mar

  19. Comparison b/w diff experience • METHODS: 1) intracorporeal suturing and knot tying, 2) intracorporeal suturing and extracorporeal tying 3) mechanically assisted suture & pretied knot device (Quik-Stitch). • 3 attending surgeons: 1 with much experience 2 with less experience 2 chief residents, with the least experience. Bermas et al, Journal of the Society of Laparoendoscopic Surgeons, 2004 Apr-Jun

  20. RESULTS: The average times in sec Bermas et al, Journal of the Society of Laparoendoscopic Surgeons, 2004 Apr-Jun
