A practical approach to the post esophagectomy CT: expected postoperative anatomy and anatomical approach to associated complication

This pictorial review aims to provide a structured approach to the interpretation of post esophagectomy CT by reviewing the major esophagectomy surgeries and conduit reconstructions, along with their associated complications at key anatomical landmarks. This paper combines an image rich experience and evidence-based approach to common and rare complications. The paper begins with an overview of the conventional Ivor Lewis esophagectomy and the expected postoperative imaging appearance (with separate detailed tables on additional surgical reconstructions), followed by a focused review of various complications at specific anatomical sites in a systematic fashion. By the conclusion of this review, radiologists will be equipped to employ a systematic approach to post-esophagectomy CT interpretation, confidently identifying both common and uncommon complications.
