Popis: The aim of this study was to analyze the volume of the gastric tube using sleeve gastrectomy (SG) 3D-computed gastrovolumetry for patients after SG and to determine its correlation with the percentage of excess weight loss. Patients who underwent SG between 2015 and 2018 were followed prospectively and evaluated after the operation. The condition of the gastric tube was examined using 3D-computer tomography reconstruction and gastric volumetry. The gastric tube was distended by effervescent sodium bicarbonate given orally. Gastric volume (GV) was estimated with the software of the CT device. The relationship between GV and weight loss was analyzed. Assessment of anthropometric parameters and the condition of the gastric tube was performed 24 months after surgery. Forty-two patients (24 women, 18 men) with a mean age of 36.9 ± 10.9 years were studied. The mean values body mass index (BMI) before and after SG were 48.1 ± 11.1 kg/m2 (from 35.3 to 81.5 kg/m2) and 34.7 ± 8.5 kg/m2 (from 26.7 to 61.3 kg/m2), respectively. There was a statistically significant difference between BMI before and after RRS (Z = –5.58; P = 0.001), after RRS BMI was significantly smaller. Mean percentage of excess weight loss (%EWL) was 52.2 ± 20.7%. Mean GV was 288.7 ± 105.2 ml. The % EWL was inversely correlated with GV after SG (rs = –0.831; P = 0.001). 3D-computer gastrovolumetry is a good method to measure GV after SG. Post-operative weight loss inversely correlates with the GV.
