Understanding the Technique of MGB: Clearing the Confusion
After almost 20 years of confusion, the Mini-Gastric Bypass (MGB) still leads to errors and patient harm when inexperienced surgeons attempt to adopt it without a clear understanding of the underlying mechanism of action and the details of the anatomy of the operation. When understood by a skilled surgeon, the MGB is a simple straightforward and very powerful operation that provides the surgeon with many advantages including the ability to tailor the operation to the patient and surgeons’ goals. The misunderstanding of the MGB and the confusion with other past and present bariatric procedures have led to poor and even deadly outcomes. This chapter is designed to educate the interested surgeon on the important details, in order to understand and safely begin training to perform the MGB.
