Definition

Noun: A surgical procedure that creates a new, permanent connection (an opening or anastomosis) between the stomach and the small intestine. This operation is performed when the normal passage from the stomach to the duodenum (the first part of the small intestine) is blocked or has been removed.

Usage

This is a highly specific medical term. It is used primarily in clinical, surgical, and anatomical contexts to describe the procedure itself or the resulting anatomical connection. * The surgeon performed a gastroenterostomy to bypass the obstructed duodenum. * After the gastrectomy, a gastroenterostomy was necessary to restore digestive continuity.

Advanced Usage

• The term specifies the creation of a "stoma" (opening) between the stomach ("gastro-") and the intestine ("entero-"). It does not specify which part of the intestine is used, though it is typically the jejunum (leading to the more specific term gastrojejunostomy).
• It is a foundational concept in gastrointestinal surgery, often discussed in relation to treating ulcers, cancers, or obstructions.

Variants and Related Words

• Gastrojejunostomy (n.): A specific type of gastroenterostomy where the connection is made between the stomach and the jejunum (the second part of the small intestine).
• Anastomosis (n.): The general surgical term for a connection between two tubular structures, such as blood vessels or loops of intestine. A gastroenterostomy is one type of anastomosis.
• Bypass (n.): A procedure that creates an alternative pathway. A gastroenterostomy is a form of gastric bypass.

Synonyms

• Gastroduodenostomy (when the connection is specifically to the duodenum, though this is less common)
• Gastrointestinal anastomosis (a more general descriptive term)
