GI and GU fluoroscopy in common post-op oncologic surgeries: what you need to know about this leaky business!

Abstract

Over the past several years, there has been a trend of decreasing screening or diagnostic fluoroscopic examinations ordered by clinical teams, particularly double contrast gastrointestinal studies. The underlying reason is due to increasing number of endoscopic procedures performed by Gastroenterology and Urology and usage of other imaging modalities, which are either more sensitive and/or offer the ability to obtain tissue for confirmation. Many fluoroscopic studies are now tailored toward patients who have undergone gastrointestinal or genitourinary oncologic surgeries, providing both functional and anatomic information, which are important tools for patient management. Some of these surgeries are very complex and an understanding of the postoperative anatomy and potential pitfalls is important to accurately evaluate for complications. The purpose of this article is to describe techniques and indications for common post-operative fluoroscopic procedures in gastrointestinal and genitourinary oncology while reviewing normal appearances. Complications, with emphasis on postoperative leaks, will be highlighted. Familiarity with the various types of gastrointestinal surgeries and urinary diversion techniques and knowledge of the expected postsurgical appearance is essential for achieving an accurate and prompt diagnosis of complications to allow for adequate treatment and management.
