Laparoscopy
To examine peritoneal cavity and its viscera A type of endoscope called a laparoscope is placed through a small
incision in the ventral abdomenCan be midline or opening into the abdominal wall (lateral to midline)
Necessary equipment Laparoscope Trocar Cannula Fiber-optic light cable Light source Veress insufflation needle Gas insufflator and hose Camera/video system (optional)
Laparoscopy: Advantages
Laparoscopy: Contraindications
Laparoscopic Equipment
LaparoscopeCome in various sizesRigid, metal tube with a light port Can also have an instrument portCannot be autoclaved
Laparoscopic Equipment
Gas insufflator Machine that allows a gas to continuously insufflate the
abdominal cavity Required for better visualization of the viscera Other parts needed: insufflation needle, sterile hose, and gas CO2 – the recommended gas due to rapid absorption
Nitrous oxide and room air are also options Must monitor intra-abdominal pressure!
Not to exceed 15 mmHg
*Tubing is connected from the gas insufflator to the Veress needle.
Gas Insufflator
Laparoscopic Equipment
Veress insufflation needleUsed during insufflation of the peritoneal cavityNeedle (trocar) pierces through abdominal layers,
into peritoneal cavity; stylet is left in placeSurgeon will connect hosing to the needleYou will connect hose to the insufflator
Laparoscopic Equipment
Trocar–cannula units Trocar punches through the abdominal wall Cannula follows, and is left in place so the laparoscope can be
inserted through it
Laparoscopic Equipment
Fiber optic light cable and light source The cable emits light from the source, through the scope.
Laparoscopic Equipment
Camera/video system (optional)

Laparoscopic Equipment
Hand instrumentsThese instruments can bepassed through cannulas of accessory ports to aid in biopsy retrieval or toperform surgical procedures.
Can grasp, cut, cauterize, staple, or biopsy.
Laparoscopic Equipment
Biopsy and grasping hand instrument tips
Laparoscopy Procedure Patient prep: fasting, bladder expressed Clip from xiphoid process to pubis; surgical scrub Recumbency depends on procedure Draping Surgeon will remove scope from sterile packaging
Glutaraldehyde or ETCO2 Sterile sleeve used to cover the camera; scope placed on the
head of the camera (camera does not get sterilized) Skin incision made Entry of Veress needle trocar is retracted insufflation tubing
can be connected to the needle Second skin incision made Entry of trocar-cannula trocar is removed scope is inserted
