Core Tip

Core Tip: Routine upper gastrointestinal swallow studies on the first postoperative day after laparoscopic one anastomosis gastric bypass have long been used to detect complications. However, our study demonstrated that these studies have no diagnostic value, with 0% sensitivity for detecting leaks or other complications. Additionally, the high cost associated with routine upper gastrointestinal studies raises concerns about their cost-effectiveness. Given these findings, reliance on clinical monitoring rather than routine imaging may improve postoperative management while reducing unnecessary healthcare costs.
