Clip Application Flashcards

A clip placed on the cystic duct is found to be applied at an oblique angle after deployment. What is the main concern?

Answer: Incomplete duct occlusion leading to possible bile leak

An obliquely placed clip may not fully occlude the duct lumen, leaving a channel for bile to leak postoperatively, which is a common cause of post-cholecystectomy bile leaks.

What is the consequence of placing a clip too close to the neck of the gallbladder on the cystic duct?

Answer: Potential for a retained gallstone to be trapped in the cystic duct remnant

Placing a clip too close to the gallbladder neck risks trapping stones in the cystic duct remnant, leading to retained stone syndrome and recurrent symptoms.

During laparoscopic clip application, the surgeon should ensure clearance of the clip applier jaws by at least how much on both sides of the target structure?

Answer: At least 3–5 mm of jaw clearance on each side

Ensuring 3–5 mm of jaw clearance on each side of the structure guarantees the clip fully encircles it and closes completely, reducing the risk of partial occlusion or misapplication.

Which of the following postoperative imaging findings would most suggest a retained or migrated clip has caused a complication?

Answer: Dilated bile ducts with clip in proximity to the bile duct on CT

Dilated bile ducts with a clip near the common bile duct on CT suggests the clip may have been misapplied or migrated to obstruct biliary flow, requiring urgent evaluation.

What is the appropriate management when a clip falls off the cystic duct stump intraoperatively during laparoscopic cholecystectomy?

Answer: Apply new clips to the stump under direct visualization after ensuring adequate tissue

Fresh clips should be applied to the stump under direct visualization after confirming adequate duct length and tissue integrity; attempting to reuse a fallen clip introduces contamination and unreliable occlusion.

In laparoscopic training simulations, what metric is most commonly used to evaluate clip application competency?

Answer: Time to apply clips combined with accuracy of placement on target structures

FLS and similar simulation programs evaluate clip application by measuring both time efficiency and accuracy of placement, as both are critical for safe operative performance.

When a cystic duct is wider than 9 mm (e.g., from chronic cholecystitis), what is the most appropriate method to secure it before transection?

Answer: Use a laparoscopic loop ligature or endoscopic stapler

A duct wider than the capacity of standard clips requires a laparoscopic loop ligature or an endoscopic stapler to ensure complete and secure occlusion before transection.
