A review of commonly performed bariatric surgeries: Imaging features and its complications

Published:November 09, 2020DOI:


      • The knowledge of the post-surgical anatomy, imaging and complications of these bariatric surgeries is essential.
      • Most commonly performed bariatric surgery is laparoscopic sleeve gastrectomy.
      • Most common complication after sleeve gastrectomy is gastric pouch dilatation.
      • Most dreaded complication after sleeve gastrectomy is perforation with postoperative leak.
      • Most common complication after gastric bypass surgery is gastroesophageal reflux disease.


      Obesity is a disease that has achieved the level that can be considered an epidemic. According to the National Center for Health Statistics data, the prevalence of obesity has increased from 30.5% in 1999–2000 to 42.4% in 2017–2018. During the same period, severe obesity has increased from 4.7% to 9.2%. With the growing prevalence of obesity, related conditions such as coronary artery disease, diabetes, and strokes have also become more prevalent.
      In the past few years, the need for bariatric surgeries such as laparoscopic Roux-en-Y gastric bypass, sleeve gastrectomy, and laparoscopic adjustable gastric banding has increased considerably. With an increasing number of bariatric surgeries, multiple postoperative complications have become common. In this review, we have attempted to describe normal postsurgical anatomical findings after bariatric surgeries and pictorial review of a few common postoperative complications.
