Abstract

Background: Some recent reports have noted that copper deficiency can occur in obese patients who have undergone bariatric surgery, such as Roux-en-Y (RY) gastric bypass or biliopancreatic diversion, or in patients who receive enteral nutrition through a jejunostomy. No reports appear to have assessed the serum copper state of patients following gastrectomy with RY reconstruction for gastric cancer.

Methods: A cross-sectional study was conducted from June 2013 to December 2014. Serum copper levels (SCLs) in 242 out-clinic patients who underwent curative gastrectomy were obtained. Patients were classified into an RY group (n = 208) and a non-RY group (n = 34).

Results: Hypocupremia was identified in 3 patients in the RY group (1.4%), and 2 patients in the non-RY group (5.9%; p = 0.146), but none experienced any symptoms caused by hypocupremia. No significant difference in the mean SCL was seen between the RY group (105.8 ± 21.2 µg/dl) and non-RY group (107.9 ± 22.7 µg/dl; p = 0.499). In the RY group, the mean SCL was significantly lower in younger patients, patients with follow-up period <3 years, and male patients.

Conclusion: Some patients developed hypocupremia after gastrectomy with RY reconstruction, but the number is acceptably low, and physical symptoms were unusual.
