- Abstract
<bold>Learning Objectives: </bold>To describe normal anatomy of Roux-en-Y gastric bypass (GBP) surgery. To know the spectrum of major complications, time of appearance and imaging findings. <bold>Background: </bold>Roux-en-Y GBP surgery nowadays represents a successful treatment of morbid obesity. From January 1999 to June 2005, 148 patients with Roux-en-Y GBP surgery have been reviewed. Within a period of 24-72 h after surgery, upper gastrointestinal series was performed. The radiographic manifestations of normal anatomy and follow-up major complications are illustrated in this pictorial essay. We compare the CT and other imaging findings with clinical and surgical findings. <bold>Imaging Findings: </bold>A total of 14 follow-up major complications occurred in 9 of 148 patients. Only 3 were early complications, the other 11 were late and appeared between 1 month and 4 years. Imaging findings of stomal stenosis, gastric staple line dehiscence, leaks, jejunal and gastric wall necrosis, small bowel obstruction due to adhesions, loculated fluid collection and celiac trunk stenosis are illustrated. <bold>Conclusion: </bold>It is important for the radiologist to be familiarized with the radiographic manifestations of normal anatomy and major complications after Roux-en-Y GBP. These may be life-threatening and usually appear as late complications. An adequate imaging technique and a prompt evaluation by the radiologist can help to minimize them.
