The data from Nelson and colleagues1 challenge the notion that GB is the “Cadillac” of bariatric operations, noting a near 20% weight loss failure rate in superobese patients at 1 and 2 years postoperation compared with only 9% and 6% after DS. In a 2006 study specifically looking at follow-up after 10 years, Christou and colleagues2 also noted rates of weight loss failure after GB of 20.4% and 34.9% at mid- and long-term follow-up. Perhaps more importantly, Nelson and colleagues demonstrated that the rates of resolution of diabetes mellitus, hypertension, hyperlipidemia, and obstructive sleep apnea were higher after DS than GB.
