Question

Which of the following statements regarding laparoscopic cholecystectomy is incorrect?

• A. Intraoperative cholangiography completely prevents bile duct injuries
• B. The Strasberg critical view technique helps reduce bile duct injury
• C. Hartmann’s pouch is pulled both laterally and medially during dissection
• D. Routine cholangiography detects common bile duct stones in about 10% of patients

Hint:

The Critical View of Safety (Strasberg) requires 3 elements:
1. Clearance of fat/fibrous tissue from the hepatocystic triangle.
2. The lower third of the gallbladder separated from the cystic plate.
3. ONLY two structures entering the gallbladder (Cystic duct and Cystic artery).

Answer 1

The Correct Option is A

Concept:
Safe performance of a laparoscopic cholecystectomy relies on strict adherence to anatomical visualization techniques. Understanding the limitations of intraoperative adjuncts like cholangiography is vital.
Explanation:
• Option A: This statement is absolutely incorrect. While Intraoperative Cholangiography (IOC) provides an anatomical roadmap and can help the surgeon recognize aberrant anatomy or detect a bile duct injury early in the operation, it cannot completely prevent injuries. In fact, dissecting the cystic duct to place the cholangiogram catheter can itself be the mechanism of injury.

• Option B: Achieving the Critical View of Safety (CVS), popularized by Strasberg, is the universal gold standard technique proven to significantly reduce the incidence of major bile duct injuries.

• Option C: Proper retraction is essential. The fundus is retracted cephalad, and Hartmann's pouch is retracted inferolaterally to open up the triangle of Calot and expose the cystic duct at 90 degrees to the CBD. Mentioning manipulating it medially/laterally during careful dissection refers to evaluating all sides of the duct to achieve CVS.

• Option D: Studies historically show that if routine IOC is performed on all patients, asymptomatic, unsuspected CBD stones are discovered in roughly 5-10% of the population.
Final Answer:
Intraoperative cholangiography does not definitively prevent bile duct injuries; rather, it aids in anatomical orientation and early recognition of injuries.
