“…The literature has reported an average of 1.23 μmol/L within 30 days after surgery and 1.54 μmol/L 18 within months. In other words, there is a decline within 30 days after DGYR, followed by an increase within 18 months of follow-up, reaching a value close to that recorded before surgery (8,9,15,16,19,20,25,29) .…”

-Background -Bariatric surgery is the most effective treatment for severe obesity, but the surgery increases the risk of developing nutritional deficiencies, such as vitamin A deficiency. In human metabolism, vitamin A plays a role in vision. Objective -To evaluate serum vitamin A, visual function and ocular surface of patients undergoing bariatric surgery. Methods -A cross-sectional and analytical study was conduced with 28 patients undergoing bariatric surgery for at least 6 months. Ophthalmologic evaluation was done through color vision test, contrast sensitivity test, ocular surface tests and confocal microscopy, as well as vitamin A serum measurement. Results -Vertical sleeve gastrectomy was performed in seven (25.0%) patients and Roux-en-Y gastric by-pass in 21 (75.0%). Mean serum vitamin A level was 1.7±0.5 µmoL/L. Most patients (60.7%) had symptoms of dry eye. Five (17.9%) patients had contrast sensitivity impairment and 18 (64.3%) color vision changes. In the group of patients undergoing Roux-en-Y gastric by-pass, mean vitamin A levels were 1.8±0.6 µmoL/L, whereas they were 1.7±0.5 µmoL/L in patients submitted to the restrictive technique vertical sleeve gastrectomy. The analysis of the influence of serum levels of vitamin A in the visual function and ocular surface was performed by Pearson correlation test and there was no significant correlation between any of the variables and vitamin A. Conclusion -There was no influence of the bariatric surgery technique used on serum vitamin A levels, on the visual function or on the ocular surface. Moreover, there was no correlation between serum levels of vitamin A and the visual function or the ocular surface changes. HEADINGS -Bariatric surgery. Vitamin A deficiency. Night blindness. Xerophthalmia.

“…Anemia has been reported to occur in up to 60% of patients after partial gastrectomy [12,13] . The incidence of anemia after bypass surgery has been reported as from 5% to 64% [7][8][9][14][15][16][17] . A recent study of postsurgical anemia after gastrectomy reported that the incidence of anemia was 37.9%, 33.5% and 34.7% at 3, 6 and 12 mo after surgery, respectively [18] .…”

AIM:To identify the incidence and etiology of anemia after gastrectomy in patients with long-term follow-up after gastrectomy for early gastric cancer. METHODS:The medical records of those patients with early gastric adenocarcinoma who underwent curative gastrectomy between January 2006 and October 2007 were reviewed. Patients with anemia in the preoperative workup, cancer recurrence, undergoing systemic chemotherapy, with other medical conditions that can cause anemia, or treated during follow up with red cell transfusions or supplements for anemia were excluded. Anemia was defined by World Health Organization criteria (Hb < 12 g/dL in women and < 13 g/dL in men). Iron deficiency was defined as serum ferritin < 20 μg/dL. Vitamin B12 deficiency was defined as serum vitamin B12 < 200 pg/mL. Iron deficiency anemia was defined as anemia with concomitant iron deficiency. Anemia from vitamin B12 deficiency was defined as megaloblastic anemia (mean cell volume > 100 fL) with vitamin B12 deficiency. The profile of anemia over 48 mo of follow-up was analyzed. RESULTS:One hundred sixty-one patients with gastrectomy for early gastric cancer were analyzed. The incidence of anemia was 24.5% at 3 mo after surgery and increased up to 37.1% at 48 mo after surgery. The incidence of iron deficiency anemia increased during the follow up and became the major cause of anemia at 48 mo after surgery. Anemia of chronic disease and megaloblastic anemia were uncommon. The incidence of anemia in female patients was significantly higher than in male patients at 12 (40.0% vs 22.0%, P = 0.033), 24 (45.0% vs 25.0%, P = 0.023), 36 (55.0% vs 28.0%, P = 0.004), and 48 mo (52.0% vs 31.0%, P = 0.022) after surgery. Patients with total gastrectomy showed significantly higher incidence of anemia than patients with subtotal gastrectomy at 48 mo after surgery (60.7% vs 31.3%, P = 0.008). The incidence of iron deficiency was significantly higher in female patients than in male patients at 6 (35.4% vs 13.3%, P = 0.002), 12 (45.8% vs 16.8%, P < 0.001), 18 (52.1% vs 22.3%, P < 0.001), 24 (60.4% vs 20.9%, P < 0.001), 36 (62.5% vs 29.2%, P < 0.001), and 48 mo (66.7% vs 34.7%, P = 0.001) after surgery. CONCLUSION:Anemia was frequent after gastrectomy for early gastric cancer, with iron deficiency being the major cause. Evaluation for anemia including iron status should be performed after gastrectomy and appropriate iron replacement should be considered.

Nutritional Consequences of Adjustable Gastric Banding and Gastric Bypass: A 1-year Prospective Study

Abstract: Severe nutritional deficits can be avoided after bariatric surgery if patients are systematically supplemented with multivitamin and carefully monitored. However, specific care is required to avoid iron and vitamin B12 deficiencies, anemia, and protein malnutrition.
