The procedure of choice for elective removal of CBD stones for most patients is
**Core Concept**
The elective removal of common bile duct (CBD) stones typically involves a minimally invasive procedure that allows for the clearance of stones while preserving the biliary tract's anatomy. This procedure is often chosen over open surgery due to its lower morbidity and quicker recovery time.
**Why the Correct Answer is Right**
The procedure of choice for elective removal of CBD stones is Endoscopic Retrograde Cholangiopancreatography (ERCP) with sphincterotomy. This involves the insertion of an endoscope through the mouth and into the duodenum, where a sphincterotomy is performed to allow access to the biliary tree. A balloon or basket can then be used to extract the stone(s) from the CBD. ERCP is preferred over other methods due to its high success rate and low complication rate. The sphincterotomy allows for the dilation of the ampulla of Vater, which enables the safe removal of stones from the CBD.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not clearly stated, so it will be skipped.
**Option B:** Not applicable, as this option is missing.
**Option C:** Not the procedure of choice for elective removal of CBD stones, as it is more invasive and typically reserved for cases where ERCP is not feasible or has failed.
**Clinical Pearl / High-Yield Fact**
It's essential to note that ERCP carries a risk of complications, including pancreatitis and cholangitis. Therefore, patients undergoing ERCP should be carefully selected and monitored post-procedure.
**Correct Answer:** C. Endoscopic Retrograde Cholangiopancreatography (ERCP) with sphincterotomy.
