Abstract:
Objective To assess the influence of laparoscopic sleeve gastrectomy (LSG) on the nutritional status in patients with obesity.Methods From August 2014 to July 2015, 24 obese patients underwent LSG in Dongfang Hospital Affiliated to Tongji University.Weight and nutritional status of these patients were measured pre-operatively and 3, 6, and 12 months after surgery.Results The mean body weight of the 24 obesity patients was (81.94±21.39) kg, (78.83±24.49) kg, (62.67±10.79) kg 3, 6, and 12 months after surgery, respectively, which were significantly lower than the preoperative body weight [(99.02±23.92)kg] (P=0.004).The serum levels of albumin, hemoglobin, and trace elements (including calcium, iron, zinc, magnesium, and copper) showed no significant change after surgery (all P>0.05).Plasma vitamin D[25(OH)D] increased significantly from (13.1±4.1)μg/L preoperatively to (19.8±5.3)μg/L 12 months after surgery (P=0.031).Folic acid was (6.2±3.9)μg/L before LSG and significantly increased to (14.2±9.2) μg/L 3 months later surgery (P=0.009);the folic acid level gradually decreased 6 and 12 months after LSG but was still higher than the preoperative level.Conclusion Vitamin D deficiency is present in obese patients before LSG.After surgery, while the serum albumin and trace elements have no obvious change, the vitamin D and folic acid levels remarkably increase.
