Optimizing detection of postoperative leaks on upper gastrointestinal fluoroscopy: a step-by-step guide

Stephany L Ross et al. Abdom Radiol (NY). 2021 Jul.

Abstract

Postoperative leaks after gastrointestinal surgery are important to identify to decrease patient morbidity and mortality. Fluoroscopic studies are commonly employed to detect postoperative leak. While the literature addresses the sensitivity and specificity of these examinations, there is generally a lack of description of the fluoroscopic technique itself and there may be variability between radiologists in how these studies are performed. It is important to balance a standardized fluoroscopy protocol while tailoring the exam for each surgical and patient situation. Here we will briefly review common postoperative anatomy in the upper gastrointestinal tract, propose fluoroscopic techniques to improve postoperative leak detection, and illustrate teaching points with clinical cases.

Keywords: Anastomotic leak; Barium; Fluoroscopy; Gastrointestinal; Perforation; Water-soluble contrast.
