Chole Flashcards
What makes up Calots Triangle
- Fundus
- Infundibulum
- Gallbladder neck
- cystic duct
- Inferior edge of the liver
- Common hepatic duct
What makes up the critical view of safety
Cystic duct
cystic artery
clear view of the liver bed
What is the pathway of bile
Travels from the GB - to the cystic duct - into the common bile duct - down to the sphincter of oddi - into the duodenum
What are the two disease states of the gallbladder
Cholelithiasis
Choledocholithiasis
What is cholelithiasis
formation of gallstones in the gallbladder
What is choledocholithiasis
gallstones in the common bile duct
What is ideal patient selection for early cases
Good performance status ASA 1-11
Non obese <30 BMI
no previous upper abd. surgery
Age 18-80
Symptoms consistent with gallbladder disease
suitable for lap. chole
Patient Positioning
Supine
strap across thighs
reverse trend ~ 10 degrees
tilt to patient L - elevate Patient R
Lower Table
Slide table if needed for C-arm to fit under the table
When/ how much ICG should you use
It should be administered about 45 minutes before case start to see Duct and 30-60 seconds to see artery
2.5 mg/ml solution - 25mg w/ 10ml sterile water
Port Placement - 4 arm
Endo 2cm superior to the umbilicus
L&R hand 8cm lateral
Hockey stick the 4th arm on the L side - holds the falciform as well as the fundus
Typical instruments used
Hook / med-large clip applier / suction irrigator - Arm 3
Prograsp / cadiere forceps - Arm 4
Fenestrated bipolar / force bipolar - arm 1
Port Placement with C-arm
Space arms 2-3 to leave space for c-arm space arms 1& 4 a fist width of clearance
Lower patient clearance joints
Cart opposite side of bed
Procedure steps 1-6
- Initial exposure
- Dissection of calots triangle and identify critical view of saftey
- Confirm with Firefly
- Ligation and division of cystic duct artery
- cystic plate dissection
- Specimen removal
Initial exposure - what happens & DV value
Take down adhesions
grasp and retract the fundus of the GB to expose cystic pedicle - using arm 4
DV value - 3DHD view - consistent/ steady view of field
Dissection of calots triangle - what happens & DV value
incise peritoneum close to GB neck to expose the landmarks
See the critical view of safety- ensure only Cystic duct and cystic artery are entering GB
DV value - Does not have to rely on assistant for retraction or view. Wrists can provide precise dissection
