Learning objectives
To describe the routine technique of water soluble uper GI evaluation of patients undergoing Roux-En-Y gastric bypass
To review the imaging findings of normal postoperative anatomy
To recognize the main complications and its imaging features especially those life-threatening
Background
Introduction
Obesity is an epidemic disease.
It is one of the main causes of preventable death.
In Mexico,
according to 2012 Encuesta Nacional de Salud y Nutrición (ENSANUT),
the prevalence of overweight and obesity in adults (Fig. 2) was 71.28% (representing 48.6 millon people).[1]Bariatric surgery is increasingly performed as a therapeutic alternative in obese patients who fail to lose weight with medical treatment.
The recommendations to perform a surgery include the following criteria: a BMI of 40 or higher,
or a BMI of 35 or...
Findings and procedure details
Postsurgical assessment and normal imaging findings
The knowledge of postoperative anatomy is crucial to rule out complications in the immediate and late postoperative period,
especially those that are life threatening.
Each surgical technique has its own special characteristics and the different types of complications must be recognized.[4]
Upper gastrointestinal examination is the modality of choice for immediate post-surgical evaluation of patients who have undergone this procedure,
it has a specificity close to 100%.[7,8] In our institution it is performed routinely to all patients in the...
Conclusion
The laparoscopic Roux-en-Y gastric bypass has become the preferred method to treat obese patients who fail to lose weight with medical treatments,
and may be considered the standard of reference for bariatric surgery.
Radiologists should be familiar with the surgical anatomy and normal imaging findings for major bariatric procedures to rule out the most frequent complications,
especially those are life threatening.
Upper GI series and abdominal CT are the preferred methods to evaluate these patients at immediate post-surgical period.
In many institutions a fluoroscopy upper...
