For bleeding varices of the esophagus, the common operation/operations is/are
**Question:** For bleeding varices of the esophagus, the common operation(s) is/are:
A. Esophagectomy
B. Esophageal variceal band ligation
C. Esophageal dilatation
D. Esophageal stent placement
**Correct Answer:** B. Esophageal variceal band ligation
**Core Concept:** Esophageal varices are dilated, tortuous veins that occur in the esophagus, usually as a result of portal hypertension due to liver cirrhosis. They can lead to life-threatening bleeding if not managed appropriately.
**Why the Correct Answer is Right:** Esophageal variceal band ligation (BVL) is a minimally invasive procedure used to treat bleeding varices. It involves placing a band around the varices to seal off the blood flow, thereby preventing further bleeding and reducing the risk of re-bleeding. This is the most effective method for controlling acute variceal hemorrhage and preventing rebleeding.
**Why Each Wrong Option is Incorrect:**
A. Esophagectomy (removal of the entire esophagus) is an extensive surgical procedure usually reserved for advanced esophageal cancer cases. It is not a standard option for treating bleeding varices.
B. Esophageal dilatation is a procedure to enlarge narrowed portions of the esophagus. It does not address the underlying cause of bleeding varices and is not an effective treatment option.
C. Esophageal stent placement is a procedure to create a passage for food to pass in cases of strictures or obstructions in the esophagus. It does not treat bleeding varices and is not a suitable option for this condition.
**Clinical Pearls:**
Esophageal variceal band ligation is a highly effective procedure in preventing rebleeding from varices due to its ability to occlude the blood vessels without causing significant collateral circulation. It is a crucial option in the management of acute variceal bleeding and can be performed endoscopically, making it a minimally invasive procedure.
In summary, BVL is the preferred method for treating bleeding esophageal varices compared to the other options mentioned.
