A 45-year-old woman undergoes elective open cholecystectomy for symptomatic cholelithiasis. Intraoperatively, the cystic artery is identified and ligated. However, the surgeon notes that the common bile duct (CBD) is densely adherent to the gallbladder fundus and cannot be safely dissected. Which of the following is the most appropriate next step?

Explanation

## Management of Difficult Cholecystectomy: Subtotal Cholecystectomy **Subtotal cholecystectomy** (leaving the gallbladder fundus in situ) is the safest approach when the CBD is densely adherent and cannot be safely dissected. ### Key Point: - **Indication**: Dense inflammation, adhesions, or fibrosis preventing safe dissection of the CBD or hepatic ducts - **Technique**: Remove the body and neck of the gallbladder; leave the fundus attached to the liver bed - **Advantage**: Avoids bile duct injury, which carries 0.3–0.7% mortality and significant morbidity - **Outcome**: Residual fundus rarely causes symptoms; recurrent stones are uncommon ### Why Intraoperative Cholangiography Doesn't Help Here: - Cholangiography identifies ductal anatomy but **does not solve the dissection problem** - The issue is **mechanical adherence**, not anatomical uncertainty - Attempting dissection after IOC increases injury risk ### Clinical Pearl: **"When in doubt, leave it out."** Subtotal cholecystectomy is preferable to a bile duct injury. Bile duct injury is a catastrophic complication requiring reoperation, ERCP, or hepaticojejunostomy. ### Comparison: | Approach | Indication | Risk | |----------|-----------|------| | **Subtotal cholecystectomy** | Dense adhesions, unclear anatomy | Minimal; residual fundus rarely symptomatic | | **CBD exploration** | Choledocholithiasis, confirmed ductal stones | Increased morbidity; not indicated here | | **Aggressive dissection** | Attempted complete removal | **High risk of bile duct injury** |
