Which are complications of the lap band?

Gastric band slippage, port or tubing malfunction, stomal obstruction, band erosion, pouch dilation, and port infection are examples of complications that may occur after laparoscopic adjustable gastric banding. Upper gastrointestinal tract imaging is often required to diagnose these complications.

How do you measure Phi angle for a gastric band?

The phi (φ) angle is easily measured. It is measured between a vertical line oriented with the spine and one along the long axis of the lap band – a normal phi angle is between 4 and 58 degrees. The lap band should also be “flat” and not “obliqued” so that it appears as a horizontal block rather than a ring.

How is lap band slippage diagnosed?

Gastric Lap Band Slippage Signs

1. Food Consumption Changes: You may notice a decrease in appetite, being able to eat more than usual, or experiencing an unexplained discomfort during and after eating.
2. Nausea or Vomiting:
3. Acid Reflux:
4. Abdominal Pain:

What are the risks of laparoscopic adjustable gastric banding?

Complications after laparoscopic adjustable gastric banding include stomal stenosis, malpositioned bands, pouch dilation, band slippage, perforation, gastric volvulus, intraluminal band erosion, and port- and band-related problems.

Can a gastric band be seen on radiologic imaging?

All these components of LAGB systems should be visible at radiologic imaging; however, older models of gastric bands may not be radiopaque and therefore may not be depicted on images.

Can a band be misplaced on a plain radiograph?

This is usually performed with the administration of 15-20 mL water soluble oral contrast agent prior to assessment. This is usually evident on plain radiographs with an abnormal Phi angle (out with accepted normal 4° – 58° range) and band lie. The band can be misplaced into perigastric fat or distal stomach with complicating outlet obstruction.

Is it normal to have fluoroscopic examination after banding?

Fluoroscopic examination can be normal in the early stages of intragastric erosion. Later on, oral contrast is seen pooling around the band tubing outside of the gastric lumen. CT may show eccentric gastric thickening with invasion of the band into the gastric lumen. Sometimes locules of gas are seen within the gastric wall underlying the band.
