Gastric bands: what the general radiologist should know

Area of Science:

• Radiology
• Bariatric Surgery
• Gastroenterology

Background:

• Obesity rates in the UK are rising, with significant percentages of men and women affected.
• Bariatric surgery, particularly laparoscopic adjustable gastric banding (LAGB), is an increasingly utilized and effective method for long-term weight management.
• LAGB is the most prevalent bariatric procedure in Europe.

Purpose of the Study:

• To provide a comprehensive review of laparoscopic adjustable gastric banding (LAGB) for radiologists.
• To detail the assessment of normal LAGB function and band adjustments under fluoroscopic guidance.
• To outline the recognition and management of common LAGB complications and discuss novel developments.

Main Methods:

• Review of current literature and radiological practices related to LAGB.
• Description of imaging appearances of commonly used gastric bands in the UK.
• Discussion of fluoroscopic techniques for band assessment and adjustment.

Main Results:

• LAGB is a key bariatric procedure with specific radiological assessment requirements.
• Common complications include slippage, erosion, and port-related issues, identifiable on imaging.
• Novel developments are enhancing LAGB efficacy and patient outcomes.

Conclusions:

• Radiologists are essential in managing LAGB, from initial assessment to complication identification.
• Understanding LAGB principles and imaging features is crucial for effective patient care.
• Ongoing innovations in LAGB technology promise improved results for obese patients.
