Abstract

Background. In the available literature, the data on the positive effects of sleeve gastrectomy in treatment of type 2 diabetes mellitus (T2DM) and impaired glucose tolerance (IGT) become more common, however, they are heterogeneous and not always unambiguous.The aim. To analyze our own results of treatment of patients with type 2 diabetes mellitus and impaired glucose tolerance, who underwent sleeve gastrectomy.Materials and methods. Retrospective cohort registry-based study was carried out. From 2016 to April 2021, 29 (19 %) and 7 (4.6 %) patients with diagnosed T2DM and IGT respectively underwent surgery. Of these, sleeve gastrectomy was performed in 13  (44.8  %)  patients with type  2 diabetes mellitus and in 5  (71.4  %)  patients with IGT. The mean duration of follow-up for T2DM and IGT patients was 14.2 ± 12.3 and 11.2 ± 9.0 months respectively.Results. The mean %EWL (% excess weight loss) in patients with T2DM and IGT was 44.1 ± 17.3 and 51.5 ± 16.9 respectively, and the mean %TWL (% total weight loss) was 25.0 ± 8.0 and 27.8 ± 6.0 respectively. At the moment of observation, all patients had normal level of fasting blood glucose. The level of HbA1c in patients with type 2 diabetes before the surgery was 8.2 ± 1.6, after surgery, at the time of observation – 5.8 ± 0.5 (U = 4; p ≤ 0.01). Targeted HbA1c values was recorded in all 13 patients with type 2 diabetes.Conclusion. Our study shows the efficiency of sleeve gastrectomy both in terms of weight loss and of the remission for patients with T2DM and IGT.
