Imaging After Bariatric Surgery for Morbid Obesity: Roux-en-Y Gastric Bypass and Laparoscopic Adjustable Gastric Banding
Section snippets
Roux-en-Y Gastric Bypass
With RYGB, a small gastric pouch is created to exclude the remainder of the stomach, duodenum, and proximal jejunum from the path of food. The gastric pouch is anastomosed to a Roux jejunal limb through a small stoma. The Roux limb typically has a short, blind-ending limb and an antegrade-flowing limb. The Roux limb may be brought to the gastric pouch through a defect in the transverse mesocolon (retrocolic) or anterior to the transverse mesocolon (antecolic). There is a jejunojejunal (JJ)
Laparoscopic Adjustable Gastric Banding
Gastric banding is a restrictive procedure that limits the volume of food that can be consumed.31 A gastric band procedure was first introduced by Kuzmak in 1986 and was made available laparoscopically in the early 1990s.32, 33, 34 The first adjustable gastric band was approved for use in the United States by the Food and Drug Administration in 2001. Since that time, additional versions of the band have been approved and the concept of a reversible, adjustable gastric band is an increasing
Summary
Obesity is a serious health problem in the United States and European countries. With failed conservative treatment and proven effectiveness of bariatric surgery, surgical procedures for morbid obesity are increasingly performed. RYGB and LAGB are the 2 most popular bariatric procedures performed currently in the United States. Bariatric surgery patients are often evaluated with UGI and/or CT, and findings of weight loss surgery may be incidental at the time of imaging for other indications.
