Objective(s)
Monitoring and prevention of long-term nutrient deficiency after laparoscopic Roux-en-Y gastric bypass (LRYGB) remains ill defined due to limited surgical follow-up after bariatric surgery. This study compared nutrient supplementation as well as surgeon and primary care physician (PCP) follow-up between patients with short-term versus long-term follow-up.
Methods
All patients undergoing LRYGB at a single institution in 2004 (long-term group, n = 281) and 2012–2013 (short-term group, n = 149) were evaluated. Prospectively collected database, electronic medical record (EMR) review and telephone survey were used to obtained follow-up for both cohorts. Multivariate logistic regression was used to assess factors independently predicting multivitamin use.
Results
Complete follow-up was achieved in 172 (61 %) long-term and 107 (72 %) short-term patients. We demonstrate a significant difference (p < 0.0001) in time since last surgeon follow-up (13.3 ± 7.8 vs 86.9 ± 39.9 months) for the long-term group with no difference in PCP follow-up, (3.1 ± 4.3 vs 3.7 ± 3.4). Nutrient supplementation was higher in the short-term group, including multivitamin (70.3 vs 58.9 %, p < 0.05), iron (84.2 vs 67.1 %, p = 0.02), and calcium (49.5 vs 32.9 %, p = 0.01). After adjusting for interval since surgery, %EBMI and current comorbidities logistic regression (c = 0.797) demonstrated shorter time since last surgeon visit was independently predictive of multivitamin use (p = 0.001).
Conclusions
While it appears patients prefer to follow-up with their PCP, this study reveals a large disparity in malnutrition screening and nutrient supplementation following LRYGB. Therefore, implementation of multidisciplinary, best-practice guidelines to recognize and prevent malnutrition is paramount in the management of this growing population of high-risk patients.
