“…In line with our findings, Bashas et al reported a significant decrease in hemoglobin levels at one-year after OAGB [26]. Other authors confirmed the previous findings after OAGB [27]. Anemia is common after OAGB, similar to or less than the rates reported after RYGB [28].…”

“…Bashah et al did not find any negative impact of OAGB on post-operative serum vitamin D levels at one year after surgery [26]. Other authors reported a significant increase in vitamin D level after OAGB, from 22.24 ng/ml before operation up to 35.52 ng/ml one year after it [27]. The same was also noticed for sleeve gastrectomy.…”

“…Other authors also reported a significant increase in the serum levels of vitamin B12 after OAGB. Zamaninour and Pellitero reported a significant rise in vitamin B12 levels one year after LSG [27,42]. On the other hand, other authors didn't record significant changes in vitamin B 12 levels after OAGB procedure [26].…”

In Egypt, sleeve gastrectomy and one anastomosis gastric bypass (OAGB) are popular bariatric procedures. The current study was conducted to compare between these two procedures regarding short-term weight loss, comorbidity improvement, vitamin and micronutrient changes. This prospective study included 40 cases who were divided into two equal groups; sleeve gastrectomy and OAGB groups. All cases received the standard perioperative care. Our primary outcome was serum nutrient changes (hemoglobin, iron, calcium, vitamin D, and vitamin B 12), while secondary outcomes included weight loss parameters along with the improvement of obesity related comorbidities. These data were recorded 3, 6, and 12 months after operation, and then compared to the corresponding baseline values. Demographic criteria were comparable between the two groups, apart from diabetes which was more prevalent in the OAGB group. Both groups were followed by a significant and comparable weight loss at the short-term after operation. Both groups were associated with significant improvement in DM and hypertension at 12 months. Most evaluated vitamin and nutrient levels were comparable between the two groups except for hemoglobin, iron and vitamin B 12 levels, which were significantly higher with sleeve gastrectomy at 6-and 12-month follow up. Both sleeve gastrectomy and OAGB are effective bariatric procedures that could achieve satisfactory weight loss and improvement of comorbidities. However, OAGB carries higher risk of iron, hemoglobin and vitamin B 12 deficiency.

Introduction: Obesity is a disease that shortens life expectancy and predisposes to many diseases such as severe hepatosteatosis. Hepatosteatosis is characterized by inflammatory infiltration of the portal space. Bariatric surgery has improvement effect on hepatosteatosis and degree of inflammation. Laparoscopic sleeve gastrectomy is an effective and most common therapeutic option for obesity. Neutrophil-lymphocyte ratio is a parameter associated with inflammatory disease. This study aimed to investigate if there is any correlation between improvements in hepatosteatosis and biochemical parameters especially Neutrophil-lymphocyte ratio and ultrasonographic findings one year after the laparoscopic sleeve gastrectomy. Methods: The files of 66 patients who underwent laparoscopic sleeve gastrectomy between May 2017 and April 2020 were retrospectively reviewed. Preoperative and postoperative one year demographic data, biochemical and inflammatory parameters and ultrasonographic reports of the liver were reviewed. Results: A statistically significant improvement in hepatosteatosis was demonstrated by ultrasonography one year after laparoscopic sleeve gastrectomy. A significant decrease was also observed in Neutrophil-lymphocyte ratio. No correlation was found between the decrease of Neutrophil-lymphocyte ratio and improvement in hepatosteatosis. There was also significant difference between the preoperative and postoperative BMI, biochemical and inflammatory parameters. Conclusion: However we found laparoscopic sleeve gastrectomy is associated with significant improvement in hepatosteatosis and inflammatory parameters, no correlation between the improvement in hepatosteatosis and NLR was seen at one-year.
