Complications of Adjustable Gastric Banding, a Radiological Pictorial Review

Abstract: Continuous progress in surgical technique of adjustable gastric banding and the increasing experience of surgeons have decreased the rate of complications. However, because different complications may have the same clinical presentation but require different treatment, to give a definitive diagnosis, the radiologist must be aware of the surgical procedures and possible sequelae.

“…This can be more formally measured using the phi angle, which is the angle created by intersecting a line drawn parallel to the spinal column with a line drawn parallel to the plane of the gastric band on an anteroposterior projection. Normally this angle should range from 4˚to 58˚ [25]. Stomal stenosis and acute concentric pouch dilatation are the most common complications after LAGB [26], and present with nocturnal reflux, vomiting and upper abdominal discomfort.…”

“…The criteria we use for abnormalities have not been validated in studies but reflect anatomic changes associated with placement of the band and in general, are widely reported. Most studies from both the surgical and radiology literature have examined outlet stenosis, esoph- ageal dilation greater than 2× normal, reflux, esophageal atony, and requirement of multiple esophageal peristaltic waves for clearance of contrast, in addition to slips, as indications for removal of fluid [12,[15][16][17].…”

“…2 The two restrictive procedures favored are the Roux-en-Y gastric bypass procedure (RYGBP; Figure 1A) and the laparoscopic adjustable gastric banding procedure (LAGBP; Figure 1B). [2][3][4] Both types usually are performed laparoscopically and have a low morbidity and mortality compared with open procedures. 2 The major advantage of the RYGBP is its effectiveness in the morbidly obese patient with a BMI ≥ 50 kg/m 2 ; the LAGBP is not as effective in this cohort.…”

“…Late strictures are not uncommon, and have been reported in as many as 27% of patients. 3,4 These strictures usually can be managed with endoscopic dilation.…”
