gastrography
Pronunciation: gas-TROG-ra-fee
Radiographic imaging of the stomach using contrast material, commonly performed to evaluate anatomy and function after bariatric surgery.
Full Definition
Gastrography is a radiographic imaging technique that uses contrast material, typically barium or water-soluble agents, to visualize the stomach's anatomy and function. In bariatric surgery contexts, gastrography (often called upper GI series or barium swallow) is frequently employed for preoperative evaluation, postoperative surveillance, and investigation of complications. The procedure can demonstrate gastric emptying, identify anatomical abnormalities, detect leaks, strictures, or obstructions, and assess the size and function of gastric pouches or sleeves. Dynamic imaging during gastrography provides information about motility and transit, which can be particularly valuable in evaluating complications such as delayed gastric emptying or mechanical obstructions following bariatric procedures.
Usage
Usage note: Often used interchangeably with upper GI series in clinical practice.
