A. Cholecystectomy is absolutely contraindicated
B. Open cholecystectomy
C. Laparoscopic cholecystectomy
D. Mini-laparotomy
Ans C - laparoscopic cholecystectomy is the procedure of choice in this population since it is well tolerated and has decreased rate of
- infection
- Bleeding
- transfusion
- Liver failure
laparoscopic cholecystectomy should be preferred over open in Child Pugh’s A and B classes in these patients.
Blumgart 6e Pg 576.

A. 10-20%
B. 5-10%
C. 2-5%
D. <2%
ans B - 5-10%
A national study in USA has shown the average conversion rate to be 5-10%, although it is higher in less experienced surgeons.
Blumgart 6e Pg 576
True of False
The antegrade or fundus down technique is used in cases of severe inflammation obstructing the visualisation of cystic duct
Ans - FALSE
this technique should not be used in this situation as there is a significant risk of biliary injury.
the cystic artery should not be dissected for more than 1cm in this technique to avoid injury to the CHD or CBD.
Blumgart 6e Pg 578.
During a partial cholecystectomy the gall bladder is opened at the -
A. Fundus
B. Infundibulum
C. Body
D. A or B
Ans - D -
the GB can be opened at the fundus (Commonly) or infundibulum. The posterior wall of the GB is left behind and the mucosa is cauterized.
If bile is found oozing from the CD stump then it is closed with surgical clips or sutures.
Blumgart 6e Pg 580
absence of the cystic duct is
A. Physiological
B. Pathological
C. Either A or B
D. Never seen
Ans B -
Absence of the cystic duct is a pathological process due to repeated bouts of inflammation, and this is usually not identified until at the time of the operation.
Blumgart 6e p580
most extra-hepatic bile duct anomaly -
A. cystic duct emptying into the RHD
B. cystic duct emptying into a right sectoral duct
C. anomalous right sectoral duct that drains into the CHD or Cystic duct
D. absence of cystic duct
Ans C -
anomalous right sectoral duct that drains into the CHD or Cystic duct is the most common anomaly in extrahepatic bile ducts.
Anomalies in the extrahepatic bile ducts can be present in as many as 12% of the patients.
Blumgart 6e p580.
what percentage of patients may have a double Cystic Artery
A. 1-2%
B. 2-12%
C. 12-25%
D. 20-30%
ans C - 12-25% patients.
also when cystic duct arises from an aberrant source it more often than not travels outside the triangle of Calot.
Blumgart 6e pg 581
most common artery injured in vasculobiliary injuries -
A. Common Hepatic artery
B. Right hepatic artery
C. Hepatic Artery proper
D. Left Hepatic Artery
Ans B - right hepatic artery is injured in 92% of cases of vasculobiliary injury.
Blumgart 6e Pg 581
Most common intraoperative complication during cholecystectomy ?
A. Gall Bladder Perforation
B. Hemmorrhage
C. Bile duct injury
D. Spilled stones
Ans A - gall bladder perforation is the most common intraoperative complication, especially during the learning curve.
but it rarely requires conversion to open.
Rates can be upto 30-40% cases.
GB spillage may cause more postoperative pain, ileus and infection.
Blumgart 6e Pg 581.
All of the following are true except -
A. most of bile duct injuries are caused by attending surgeons
B. Most of the bile duct injuries go unrecognized intraoperatively
C. most common cause is misperception of the normal anatomy
D. Routine use of cholagiography is the current standard technique to reduce the rate of bile duct injuries.
Ans D -
Routine use of Intra-op cholangiography was initially proposed to reduce injury. However it is no longer recommended routinely since
- there is a risk of injury while performing Cholangiography itself.
- proper interpretation of the anatomy on cholangiography remains challenging.
Critical view of safety is the current standard technique to reduce the rate of bile duct injuries.
Blumgart 6e Pg 581.
Classic injury of laparoscopic cholecystectomy occurs when -
A. Cystic duct is mistaken for CBD
B. Anomalous right sectoral duct is ligated.
C. Cystic duct is mistaken for CHD
D. CBD is mistaken for Cystic duct
Ans D -
the classical injury during laparoscopic cholecytectomy is when the CBD is mistaken for being the Cystic duct and clipped.
Blumgart 6e Pg 582
which of the following is not true regarding the classic injury in laparoscopic cholecystectomy ?
A. Cystic duct is mistaken for CBD and clipped.
B. Cystic duct is pulled too vigorously laterally causing the Cystic duct and CBD to stretch into alignment and appear as one.
C. The left side of CHD is mistaken to be the underside of the GB.
D. CHD is misidentified as a second cystic duct or an accessory duct
E. Right hepatic artery is the most commonly associated arterial injury in this scenario
Ans A - CBD is mistaken as the cystic duct and divided, and not the other way around.
- CBD is mistaken as cystic duct due to excessive lateral traction causing the cystic duct and CBD to become aligned and appear as one.
- the dissection then continues postero-superiorly along the left side of the CHD believing it to be the underside the GB
- the CHD is then divided as the surgeon tries to dissect while he or she believes to be dissection the ‘GB from the liver bed’ -
at this point even if the CHD is identified as a bile duct it is often considered to be a second cystic duct or accessory duct, and therefore if this is also ligated then a even more proximal injury occurs.
Blumgart 6e Pg 582
What should be the best course of action if a bile duct injury is identified at the time of surgery ?
A. assess the extent of injury, and one’s own ability to repair it.
B. assess patient’s current condition, resources of the hospital and availability of specialized hepatobiliary expertise.
C. often the most prudent action is to terminate the surgery, leave a drain, and close the patient with immediate referral to a specialized hepatobiliary centre.
D. all of the above.
Ans D - all of the above.
Early referral to a specialist centre results in a better long term outcome.
