  1. Complications in Laparoscopic Urology Dr. Anmar Nassir, FRCS(C) Fellowship in Andrology (U of Ottawa) Fellowship in EndoUrology and Laparoscopy (McMaster Univ) Chairman, Department of Surgery Umm Al-Qura Univ Consultant Urology, King Faisal Specialist Hospital, Jeddah

  2. Major Complications of Transperitoneal Abdominal Laparoscopic Surgery Urology 2004; J Urol 2002

  3. Procedural Complications Complications Related to Obtaining the Pneumoperitoneum Placement of Secondary Trocars GA Unique to Laparoscopy Exiting the Abdomen Complications in the Early Postoperative Period Late Postoperative Complications

  4. Complications of Obtaining the Pneumoperitoneum Malfunction of Equipment Closed Access (Veress Needle Placement) Insufflation and Pneumoperitoneum Open Access (Hasson Technique) "Blind" Placement of the First Trocar after Veress Needle

  5. Complications Associated with Closed Access (Veress Needle Placement) Preperitoneal Placement Vascular Injuries Visceral Injuries

  6. Complications Related to Insufflation and Pneumoperitoneum Bowel Insufflation Gas Embolism Barotrauma Subcutaneous Emphysema Pneumomediastinum, Pneumothorax, and Pneumopericardium

  7. Complications Related to Initial "Blind" Placement of the First Trocar Injury to GI Organs Injury to the Urinary Tract Injury to Intra-abdominal Vessels

  8. Contents of Hemorrhage Tray for Laparoscopic Surgery Laparoscopic Satinsky clamp 10-millimeter suction/irrigation tip Endostitch device with 4-0 absorbable suture LapraTy clip applier and clips 4-0 vascular suture on an SH needle with a LapraTy clip preplaced on the end Two laparoscopic needle drivers Topical hemostatic agent of choice

  9. Complications Related to Placement of Secondary Trocars Bleeding at the Cannula Site

  10. Position-Related Problems

  11. Complications Related to GA Unique to Laparoscopy Cardiac Arrhythmias and Cardiac Arrest Changes in Blood Pressure Aspiration of Gastric Contents Hypothermia

  12. Complications Related to the Surgical Procedure Bowel Injury: Electrosurgical Mechanical Vascular Injury Pancreatic Injury Splenic Injury Injury to the Urinary Tract Bladder Injury Ureteral Injury Injury to Nerves

  13. Injury to Nerves 45/1650 = 2.7%. These include abdominal wall neuralgia (14) extremity sensory deficit (12) extremity motor deficit (8) clinical rhabdomyolysis (6) shoulder contusion (4) back spasm (2) Wolf et al, Urology 2000

  14. Complications Related to Exiting the Abdomen Bowel Entrapment Bleeding at the Sheath Site

  15. Complications in the Early Postoperative Acute Hydrocele Scrotal and Abdominal Ecchymosis Pain Incisional Hernia Deep Venous Thrombosis Wound Infections Rhabdomyolysis

  16. Late Postoperative Complications Lymphocele Formation Chylous Ascites

  17. Ergonomics 8-22 of Lap. Surgeons reported pain, numbness, stiffness and eye strain (Hemal, 2002) It is due to; Posture Visualization Manipulation Monitor should be at the head level or 10-20 degrees lower Use step stool to work comfortably

  18. Before starting select your patient • Pt w severe COPD • further studies (i.e., ABG and PFT) are required. • In severe COPD, helium as an alternate. • Significant cardiac arrhythmias • evaluated • treated hypercarbia and the resulting acidosis may have adverse effects on the myocardium.

  19. Absolute contraindications • Uncorrectable coagulopathy • Intestinal obstruction • Abdominal wall infection • Massive hemoperitoneum/hemoretroperitoneum • Generalized peritonitis • Retroperitoneal abscess • Suspected malignant ascites

  20. Relative contraindications • BMI, according to the WHO • Overweight = • 25 to 29.9 kg/m2 • Obese = • 30 to 34.9kg/m2 • Morbid obesity= • > 35 kg/m2

  21. Relative contraindications(if …) • Morbid Obesity • Extensive Prior Abdominal or Pelvic Surgery • Organomegaly • Ascites: Benign Etiology • Pregnancy • Hernia • Iliac or Aortic Aneurysm

  22. Relative contraindications(if …) • Morbid Obesity • Extensive Prior Abdominal • Organomegaly • Ascites: Benign Etiology • Pregnancy • Hernia • Iliac or Aortic Aneurysm

  23. Creating a pneumoperitoneum There are 4 basic techniques used • Veress needle • direct trocar insertion • optical trocar insertion • open laparoscopy Gu¨nenc et al. Surg Laparosc Endosc Percutan Tech, 2005

  24. Sites for verse needleUpper quadrant access • 622 consecutive cases. • Prior abdominal surgery in 31% • body mass index was 30 or greater in 98 patients. • 92% successful placement • 5%  minor liver laceration, managed conservatively • 3%  the omentum or falciform ligament was traversed without significant injury. No major complications, such as vascular or hollow-organ perforation, were caused by either the Veress needle or trocar. No patient developed an incisional hernia at the upper quadrant trocar site Chung et al, Urology 2003

  25. Direct trocar insertion 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

  26. 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

  27. 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

  28. Physiological changes to pneumoperitoneum

  29. Few words about HAL

  30. Hand-port incisional hernias • 50 laparoscopic hand-assisted radical nephrectomies. • Closed with #1 polydioxanone sulfate suture in a running fashion. • Three (6%) patients developed hernia. All in midline hand-port sites. • The average body weight of those who developed an incisional hernia was 137 kg. JSLS, 9: 196–198, 2005

  31. Hand-port incisional hernias • Risk Factors • obesity • earlier return to activity • Conclusion: • nonabsorbable suture + interrupted closure • limited activity 4-6 wks post op if high risks. • No further wound hernias since adopting these changes JSLS, 9: 196–198, 2005 Clayman.
