What is the surgical connection between the upper portion of the stomach and the duodenum called?

• A. Cardiac catheterization
• B. Gastroduodenostomy
• C. Carotid endarterectomy
• D. Esophageal varices

Answer: (B)

The main concept here is creating a surgical connection between two hollow organs. When the upper part of the stomach is connected directly to the duodenum, the procedure is called gastroduodenostomy. The name breaks down into gastr- (stomach), duodeno- (duodenum), and -stomy (forming a new opening). This type of anastomosis is used in procedures where part of the stomach is removed and a direct link to the duodenum is restored, such as in a Billroth I operation. It differs from a gastrojejunostomy, which connects the stomach to the jejunum.

The other options refer to unrelated procedures or conditions: cardiac catheterization involves access to the heart; carotid endarterectomy removes plaque from the carotid arteries; esophageal varices are swollen veins in the esophagus.
