Are zinc absorption and zinc status reduced after Roux-en-Y gastric bypass : a randomized study using 2 supplements?
Zinc status is impaired after RYGBP, despite the finding that dietary plus supplemental zinc doubled recommended zinc intakes in healthy persons. Zinc absorption capacity is significantly reduced soon after RYGBP, with no major changes until 18 mo after surgery.
Our results suggest that hyperfibrinogenemia may provide favorable circumstances for cancer cells to metastasize via the lymphatic system. Preoperative plasma fibrinogen level is a useful predictor of lymphatic metastasis in intestinal-type gastric cancer.
