Laparoscopic cholecystectomy
Why are we operating?
Removal of the gallbladder through ports, built around one idea: never divide a structure until the Critical View of Safety proves what it is.
Indication: Symptomatic gallstones, cholecystitis, biliary dyskinesia, gallstone pancreatitis after recovery.
Read the imaging first

Practice before you scrub
Read the gallbladder
Fatty-food pain for months, now constant for 18 hours with fever. RUQ ultrasound. (Fictional educational case.)
- Stones plus an inflamed wall plus a tender probe is cholecystitis: the operation is laparoscopic cholecystectomy on this admission, not a deferred clinic date.
- The duct's calibre on the same scan sequences the pathway: dilated means the duct is interrogated before the gallbladder leaves.
The operation in 6 steps
01Access & insufflation
Pneumoperitoneum established (commonly at the umbilicus), then ports placed under vision.
Why: CO2 lifts the abdominal wall off the viscera to create working space; every later step depends on this room to see and move.
02Exposure
The fundus is pushed over the liver edge toward the shoulder; the infundibulum is pulled laterally.
Why: Lateral traction on the infundibulum opens the hepatocystic triangle; pulling upward instead aligns the cystic duct with the common bile duct, the set-up for the classic injury.
03Critical View of Safety
The hepatocystic triangle is cleared of fat and fibrous tissue until only two structures enter the gallbladder, and the lower third of the gallbladder is separated from its liver bed.
Why: The Critical View is an identification standard, not a dissection technique: if three structures are visible, or the view cannot be achieved, the answer is to stop and reassess, not to clip and hope.
04Clip & divide
Cystic duct and cystic artery are each clipped (typically two proximal, one distal) and divided.
Why: Clips only go on structures the Critical View has proven; the proximal double clip is insurance on the side that stays with the patient.
05Gallbladder off the liver bed
Diathermy dissection separates the gallbladder from the cystic plate, fundus-ward.
Why: Staying in the avascular plane between gallbladder and liver keeps the field dry; straying into liver causes ooze that obscures everything downstream.
06Extraction & closure
Gallbladder retrieved in a bag through a port site; ports removed under vision; fascia of larger ports closed.
Why: The bag keeps bile and stones out of the wound; closing 10 mm+ port fascia prevents the port-site hernias that follow shortcuts here.
Danger zones
Common bile duct
Inflammation shortens and tents the cystic duct until the common duct can masquerade as it; the classic injury is clipping and dividing the wrong duct with complete confidence.
Right hepatic artery
Often loops close to the cystic artery; injury can devascularise the right liver.
Duodenum
Sits just below the porta, thermal injury from diathermy can present days later as a leak.
Anatomy you need
Trace the biliary tree from gallbladder to ampulla; the pancreas is kept on because the common duct disappears into its head.
What can go wrong
Bile leak
Right upper quadrant pain, fever, and bilious drain output, or a patient who is simply failing to thrive after cholecystectomy.
Postoperative bleeding
Tachycardia first, hypotension late; falling urine output; a distending abdomen or rising drain output.
Surgical-site infection
Wound erythema, warmth, discharge, and pain out of proportion, typically from postoperative day 4–7.
