gastric fundus
Pronunciation: GAS-trik FUN-dus
Upper curved portion of the stomach above the level of the cardiac orifice, important in fundoplication procedures.
Full Definition
The gastric fundus is the dome-shaped upper portion of the stomach that extends above the level of the cardiac orifice and the esophagogastric junction. This anatomical region is particularly important in anti-reflux surgery, as it provides tissue for fundoplication wraps around the distal esophagus. The fundus is also the typical location for percutaneous gastrostomy tube placement and is involved in sleeve gastrectomy procedures. Understanding fundal anatomy is essential for proper surgical planning and accurate documentation of gastric procedures.
Usage
Usage note: Distinguish from other gastric anatomical regions in documentation.
