Laparoscopy

Advantages
Disadvantages 
  • Smaller incisions, reduced tissue trauma
  • Reduced post-op pain
  • Decreased incidence of wound complications
  • Decreased physiological insult to patient
  • Reduced inpatient stay
  • Improved cosmesis
  • Absent tactile feedback
  • Difficult haemorrhage control
  • Learning curve
  • May need consersion to open

 

Contraindications (things that really need open procedures being done)

  1. General
    • Coagulopathy
    • Shock
  2. Specific
    • Peritonitis
    • Obstruction

 

Essential components

  1. Establish pneumoperitoneum
  2. Insertion of trocar
  3. Inpection of cavity
  4. Removal of trocar and closure of wounds

 

Pneumoperitoneum

  1. Trendelenburg position (head down) - position bowel away from pelvis
  2. 1-2cm infraumbilical incision (transverse or vertical), deepen down to rectus sheath
    • Closed laparoscopy - Veress needle
      1. Hold up abdominal wall, insert Veress needle perpendicular to skin until "give", then point needle towards pelvis at 45'
      2. Confirm satisfactory insertion - saline drop test or aspiration
    • Open laparoscopy - Hassan cannula
      1. Pick up / incise rectus sheath. Place sutures on each side of linea alba
      2. Incise peritoneum and enter peritoneal cavity under direct vision
      3. Insert finger, sweep away adhesions
      4. Insert port + stay sutures
  3. CO2 insufflation (aim pressure 0-5mmHg)
  4. Percuss abdomen to ensure symmetrical abdominal distension
  5. Maintain pressures of 13-15mmHg, volume of gas 4-5L

 

Insertion of trochar

  1. Introduce cannula using corkscrew technique (aim towards pelvis) - check position by releasing gas tap/vavle (hearing air)
  2. Attach camera
  3. (Bleeding can be controlled by inserting a foley catheter to achieve compression)

Insert other ports under direct vision

Position of ports

1. Infra-umbilical pneumoperitoneum (veress/hassan)

2. Epigastric trochar / camera

3. Epigastric cannula

 

Finishing

  1. Remove under direct vision
  2. Check port site for haemostasis
  3. Umbilical/epigastric ports should be closed formally
  4. Skin closure by tapes/sutures
  5. + wound infiltration with bupivacaine for analgesia

 

 

Common complications

  1. Rectus sheath insufflation, gives high pressures - stop
  2. Misting of equipment (if not adequately pre-warmed)
  3. Blood on lens can be wiped on omentum
