Core Tip
Core tip: In most bariatric centres, a routine upper gastrointestinal (UGI) study is performed in the early postoperative period. Yet, the real value of a standard postoperative radiological exam after laparoscopic Roux-en-Y gastric bypass is debatable. From the available data, an UGI is not necessary as a standard postoperative exam and, similarly, a routine computed tomography (CT) scan might not be indicated. For patients who experience unexpectedly difficult surgery or abnormal postoperative clinical course, CT is the diagnostic tool of choice, especially considering that a number of patients with pathological findings in UGI contrast studies will additionally undergo CT scan.
