- Radiographically, the proximal gastric pouch is eccentrically and often markedly dilated (> 4cm), and the radio-opaque gastric band projects left to the spine, roughly 5 cm below the diaphragm. Compared to normal inclination, malpositioned bands are rotated clockwise to a more horizontal position or oriented “en face”.
Dec 9, 2022 · Gastric band slippage is a late complication of laparoscopic gastric banding surgery performed for obesity. It is reported to occur in 4-13% of cases 1-3. It can occur in either an anterior or posterior direction.

Performed laparoscopically, a silicone band device is placed around the stomachto reduce its volume. The band is adjustable via a port placed in the subcutaneous tissues of the abdomen, which can be filled with a variable volume of liquid to tighten or release the band constriction.
Imaging can be used to assess for complications such as 1-3: 1. gastric perforation(rare) 2. gastric band erosion 3. band slippage 4. pouch dilatation 5. port-site infection 6. port site hernia 7. tube detachment or leak 8. flipped port or migrated port The band, port and the tubing between them is also visible on plain radiographs. The port can be...
Fluoroscopy demonstrates a gastric band device with a more horizontal lie than normal. The phi angle measures 63 degrees (normally 4-58 degrees), indicative of a slipped gastric band. The phi (φ) angle is easily measured.
Jun 27, 2012 · The article provides an overview of the techniques and systems used in laparoscopic adjustable gastric banding, describes normal postoperative imaging appearances and imaging features that are suggestive or indicative of complications, and briefly discusses the most appropriate method for managing each complication.

The purpose of this article is to describe a sign on radiography for gastric band slippage, a complication of adjustable gastric banding surgery, and to emphasize the im-portance of this finding to radiologists and clinicians. MATERIALS AND METHODS.
Dec 17, 2018 · The commonest differential diagnosis of BS is acute (from band overtightening) or chronic (from excessive filling and adhesions) stomal stricture, with concentric pouch dilatation, nonobstructed stoma and normal band positioning, generally relieved by band loosening.
May 6, 2022 · A slipped gastric band becomes more horizontal in position with a phi angle greater than the normal 58° on radiograph . In our study, we defined a normal phi angle on coronal CT as 20–60°, and measurements outside of this range had an 89% sensitivity and 86% specificity of band slippage.
