Patients who underwent Roux-en-Y gastric bypass surgery (RYGB) without long-term bariatric specialist follow-up experienced a significantly higher rate of anemia at 10 years than did patients who had such specialist follow-up, according to findings from a database review.
Among 74 patients available for analysis – 58 men and 16 women with a mean age of 51 years who underwent RYGB at a single Veterans Affairs medical center between 2002 and 2006 – the mean rate of preoperative anemia was 20% (15 patients). The rate increased to 28% (21 patients) at 1 year, 31% (23 patients) at 5 years, and 47% (35 patients) at 10 years, according to a research letter by Gao Linda Chen, MD, and her colleagues in the surgical service of the VA Palo Alto (Calif.) Health Care System (JAMA Surg. 2017. Sep 20. doi: 10.1001/jamasurg.2017.3158).
Among 58 patients with no bariatric specialist follow-up after 5 years, the anemia rate increased from 22% (13 patients) before surgery to 57% (33 patients) at 10 years, while the corresponding rates for those with specialty follow-up were 19% (3 patients) and 13% (2 patients). After adjustment for preoperative anemia, those without specialist follow-up had significantly higher odds of anemia at 10 years (odds ratio, 6.1).
“Long-term complications of RYGB, such as anemia, may go unrecognized by nonbariatric specialists,” the investigators wrote, noting that the high rates of anemia at 10 years “may reflect a mixed vitamin and mineral deficiency, because patients had normocytic anemia.
“Our study suggests that follow-up with bariatric specialists more than 5 years after surgery, rather than with specialists with no bariatric expertise, can decrease long-term anemia risk,” they continued. “This finding may demonstrate the bariatric specialist’s specific understanding of the long-term risk for nutritional deficiency after RYGB and the importance of vitamin and mineral supplementation.”
The findings suggest a bariatric team approach with planning for long-term follow-up. “We implemented a hub-and-spoke model for bariatric care, including health care specialist education, in which the bariatric team communicates regularly with the patient’s primary care clinician before and after surgery.”
Although the study is limited by small sample size, the findings nevertheless underscore that “long-term follow-up should be an integral part of bariatric programs, and additional studies are needed to identify potential barriers to successful follow-up,” they concluded.
