Assessment of gastric sleeve resection efficacy in treatment of patients with obesity

Aim. To study the efficacy of longitudinal resection of the stomach in treatment of patients with obesity according to the results of two-year follow-up after the surgery.

Methods. During the period between 2012 and 2015 24 patients with obesity were operated on. In all of them longitudinal resection of the stomach was performed. The age of the patients was 21 to 63 years, mean body weight was 118.8±18.67 kg, mean body mass index (BMI) was 42.3±5.8 kg/m2. Before and after the surgery evaluation of excess weight, presence and characteristics of anemia (red blood cell count, concentration of hemoglobin, serum iron and vitamin B12) and quality of life according to Hamilton scale was performed.

Results. Weight loss during the first 2 years after the longitudinal resection of the stomach was 68% and it was less pronounced in patients with increased BMI. In patients with BMI <35 kg/m2 at the admission body weight was close to normal by the end of the first year after the surgery. In 4 patients with iron deficiency anemia after 2 years of follow-up hemoglobin concentration was 15.7% below its average preoperative level. 5 (20.8%) patients developed postoperative pernicious anemia. The average concentration of vitamin B12 in observed patients was 421.4±87.9 pmol/L before the surgery and 316.8±64.3 pmol/L after 2 years (p <0.001). Patients’ quality of life was noted to be improved after the performed surgery.

Conclusion. Longitudinal resection of the stomach is a very effective method of obesity treatment; it allows to achieve significant loss of excess body weight and to improve patients’ quality of life.
