“…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. It may be due to iatrogenic overfilling of the band, post-operative stomal oedema or blockage of the stoma by food bolus.…”

“…Incidence ranges from 3% to 13% and is decreasing with modifications to the surgical technique [26][27][28][29]. Anterior prolapse is more common and results in lateral eccentric gastric pouch enlargement, stomal narrowing and a horizontally orientated band, with a phi angle of greater than 58 ( Figure 9) [11,30].…”

ABSTRACT. Obesity is an increasingly prevalent and costly problem faced by the healthcare system. The role of bariatric surgery in managing obesity has also increased with evidence showing a reduction in long-term morbidity and mortality. There are unique challenges faced by the radiology department in providing an imaging service for this population of patients, from technical and staffing requirements through to the interpretation of challenging post-surgical images. We describe these challenges and provide an overview of the most frequently performed procedures, normal postoperative imaging findings and the appearance of common complications. ObesityObesity is a multifactorial disease, which is increasing in incidence and prevalence. In 2006, 67% of men and 56% of women were classified as being either overweight or obese in England [1]. Overall, 24% of adults were classified as obese, an increase from 15% in 1993, and 16% of children aged 2-15 years were classified as obese, an increase from 11% in 1995. Estimates suggest that at the current rate of increase, by 2010 there will be 12 million adults and 1 million children categorised as obese. The body mass index (BMI, kg m -2 ) is the most widely used measure of obesity; BMI between 25 and 30 signifies being overweight and BMI greater than 30 signifies obesity. BMI greater than 35 with obesityrelated serious comorbidities or greater than 40 with or without comorbidities is defined as morbid obesity.
