Abstract

Background/Aim: Little data is available on body composition and biochemical parameter changes after one anastomosis gastric bypass (OAGB) surgery. This study was therefore conducted to assess body composition and biochemical parameter changes in patients who underwent OAGB. The relationship between the percentage of total weight loss (%TWL) with percentage changes in body composition and biochemical parameters was measured in the first year after surgery. Materials and Methods: This retrospective study was carried out on 363 patients (mean age 39.93 ± 9.98 years) who underwent OAGB between January 2011 and November 2018. Anthropometric, body composition and biochemical measurements were recorded before and 1 year after surgery. For paired data, a paired sample t test or Wilcoxon test was used. Spearman or Pearson correlation test was used to evaluate the relationship between % TWL and changes in body composition and biochemical parameters. Results: The average %TWL at 1 year following surgery was 35.72 ± 6.85. Fat and muscle tissue and also serum levels of glycemic parameters, low density lipoprotein, triglycerides (TG), total cholesterol, zinc, albumin, hemoglobin, hematocrit, and platelet had decreased a year after OAGB (P < 0.05). The postoperative levels of HDL-c, vitamins D, B12, and folic acid were dramatically higher than the preoperative values. Higher %TWL significantly correlated to greater decreases in body fat, muscle mass, and serum TG at 1 year post-surgery, compared to preoperative values. Conclusion: OAGB may be effective over a follow-up period of 1 year in achieving weight, fat mass reduction, and improved serum levels of glycemic parameters and lipid profiles. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.
