Gastric band malposition is an early complication of laparoscopic gastric band procedures.
CT and fluoroscopy are commonly used to assess for gastric band complications, malpositioning is usually evident on plain radiographs.

Phi angle is measured from the frontal radiograph which was about 90 degrees... suggestive of abnormal position of a slipped gastric band.
Case Discussion
The phi (φ) angle is measured between a vertical line to the spine and another along the long axis of the lap band. A normal phi angle is ranging between 4 and 58 degrees. The phi angle is a useful measure in assessing of gastric lap band position. This patient is need to revise the position of the slipped band.
