背景：胃成形术可显著减少食物摄入量并显著减轻体重。这可能会对营养产生影响，尽管预计通过良好的建议和补充剂的使用可以最大限度地减少这种影响。方法：对26名肥胖受试者在改良长垂直胃成形术（MLVG）前后进行了详细研究，在这种环境中，可以随时获得有关避免症状的全面营养建议，并建议补充多种维生素。术前、术后2、5（n = 22）和12个月（n = 11）测量营养摄入量和人体测量值。结果：在相应的时间点，平均体重减轻分别为初始体重的13%、22%和31%。术后能量摄入（El）显著减少，平均蛋白质摄入量仅为40 g/d。在2个月时，从食物中平均摄入的铁、钙和锌分别为澳大利亚推荐膳食摄入量（RDI）的40%、71%和39%，5个月时铁和锌的摄入量仍低于RDI的一半。只有定期坚持维生素/矿物质补充剂，使铁和钙的摄入量接近RDI，但锌仍然很低。血红蛋白和血清铁蛋白浓度没有显著变化，并保持在参考范围内，但血清叶酸显着下降5个月和12 months.by 5个月，60%的受试者从未复发或复发少于每周一次。新鲜面包是最难忍受的食物。反流的频率与充足的营养insure.CONCLUSIONS：结果强调需要定期随访的MLVG患者，营养咨询，其中包括饮食质量以及症状管理，并定期摄入的维生素/矿物质补充剂，至少一年后。然而，蛋白质摄入量低仍然是一个潜在的长期问题。
BACKGROUND: Gastroplasty results in a considerable reduction in food intake and dramatic weight loss. This is likely to have a nutritional impact, although it is expected that this may be minimised by good advice and supplement use.METHODS: Twenty six obese subjects were studied in detail before and after modified long vertical gastroplasty (MLVG), in a setting where comprehensive nutritional advice on symptom avoidance was readily available and multivitamin supplements advised. Nutritional intake and anthropometry were measured preoperatively and at 2, 5 (n = 22) and 12 months (n = 11) postoperatively.RESULTS: Mean weight loss was 13%, 22% and 31% of initial body weight at the respective time points. Energy intake (El) was significantly reduced postoperatively, with the mean protein intake being only 40 g/d. At 2 months, mean intakes of iron, calcium and zinc from food were 40%, 71% and 39%, respectively, of the Australian recommended dietary intake (RDI), and iron and zinc intake remained below half the RDI at 5 months. Only regular adherence to the vitamin/mineral supplement, brought iron and calcium intakes close to RDI, but zinc remained low. Haemoglobin and serum ferritin concentrations did not alter significantly and remained within the reference range, but serum folate fell significantly between 5 months and 12 months.By 5 months, 60% of subjects never regurgitated or regurgitated less than once a week. Fresh bread was the least tolerated food. Frequency of regurgitation was not correlated with adequacy of nutrient intake.CONCLUSIONS: The results emphasise the need for regular follow-up of MLVG patients, and nutritional advice which includes diet quality as well as symptom management, and regular intake of the vitamin/mineral supplement for at least a year postoperatively. Low protein intakes, however, remain of potential long-term concern.
