Clip Application Flashcards

A standard medium-large titanium clip is typically appropriate for structures with a diameter up to:

Answer: 9 mm

Medium-large clips are designed for structures up to approximately 9 mm in diameter; structures larger than this require larger clips or an alternative occlusion method.

When using a 10 mm clip applier, the surgeon notices the jaws cannot fully close around the cystic duct. What is the most appropriate next step?

Answer: Dissect more tissue to thin the duct before re-applying

Additional dissection to remove pericholecystic fat from the cystic duct allows the clip to fully encircle and occlude it; applying clips on a thick structure risks incomplete closure.

Which of the following best describes the 'lock-out' feature found on many laparoscopic clip appliers?

Answer: Prevents accidental clip deployment when not in the operative field

The lock-out mechanism prevents accidental firing of clips when the jaws are open and not positioned around a structure, improving safety during instrument manipulation.

During laparoscopic cholecystectomy, a clip is inadvertently placed across what appears to be the common hepatic duct. What is the immediate recommended action?

Answer: Immediately convert to open surgery for biliary reconstruction

Injury to the common hepatic duct requires immediate conversion to open surgery for proper biliary reconstruction; attempting laparoscopic correction risks further injury.

What is the advantage of using polymer locking clips (e.g., Hem-o-lok) over standard titanium clips for laparoscopic procedures?

Answer: They provide a self-locking mechanism reducing risk of dislodgement

Polymer locking clips feature a ratcheting mechanism that locks them in place once applied, significantly reducing the risk of accidental dislodgement compared to non-locking titanium clips.

In the FLS box trainer, clip application tasks are designed to assess which fundamental laparoscopic skill?

Answer: Depth perception and bimanual tissue manipulation in a 2D video environment

Clip application in the FLS trainer evaluates the surgeon's depth perception and bimanual coordination when working with 2D laparoscopic video, which are key skills tested by the FLS program.

When applying clips to the cystic artery, which anatomical variant most increases the risk of an inadequate clip placement?

Answer: A short cystic artery arising directly from the right hepatic artery

A short cystic artery leaves minimal length for clip placement between its origin and the gallbladder wall, increasing the risk of the clip slipping off or injuring the right hepatic artery.
