Learning objectives
Analyze the methods of customization in the acquisition of images of the bariatric patient.
Recognize the techniques of bariatric surgery and identify the postoperative anatomy.
Review the expected complications and detect potential "pitfalls" at the time of reading.
Background
Obesity is a disease that has reached epidemic proportions worldwide. Over the past two decades, bariatric surgery has become a very popular treatment for morbid obesity.
Postoperative computed tomography (CT) of patients with morbid obesity may be difficult or impossible because of excess weight, abdominal circumference and associated medical conditions.
During the last decade, advances in CT technology have resulted in reduced acquisition time and improved image quality. This contributes to its greater use in the detection of complications and offers the added advantage of...
Findings and procedure details
Bariatric surgery is the most invasive form of treatment for obesity, so it is ideally reserved for patients who do not lose weight with diet, exercise and behavior modification (1).
When is Bariatric Surgery an option?(Fig. 2)
The NIDDK (National Institute of Diabetes and Digestive and Kidney Disease) says that bariatric surgery is an option in:
Adults who have:
BMI> 40
BMI> 35 + a related serious health problem (Diabetes, Heart Disease or Sleep Apnea)
Adolescents who have passed puberty and have reached their adult...
Conclusion
Radiologists should be familiar with the surgical technique and post-surgical radiological anatomy for the correct interpretation and detection of complications.
It is essential to customize the study in each patient, regarding the bypass technique, possible complications and specific situations.
Communication with the surgeon is essential, in order to clearly understand the surgical technique used, which will facilitate the search for complications.
