BACKGROUND: Obesity is a metabolic disorder that affects multi-systems. The liver is affected as non-alcoholic fatty liver disease. Among several treatment modalities, surgery is the most successful method. Previous studies showed that, as other obesity-related morbidities, NAFLD can be reversible after surgery. Transient elastography is a reliable modality to demonstrate these changes pre- and postoperatively. Although the measurement of the volume and elasticity of the gastrectomy specimen show significant relations with excess weight loss, the relation between NAFLD and these gastric measurements is unclear and needs to be analyzed.
METHODS: We retrospectively analyzed 60 patients, who operated with laparoscopic sleeve gastrectomy, from November 2016 till may 2018. We collected demographic data, preoperative and postoperative 3rd-month anthropometric measurements, preoperative liver stiffness measurement (LSM) and Controlled Attenuation Parameter (CAP) by transient elastography. Volume, expansion capacity and size measurements of sleeve gastrectomy specimen under the pressure of 10mmHg with CO2 insufflation was also evaluated.
RESULTS: The volume of gastric specimen is significantly correlated with LSM and CAP (p<0.05). The excess weight is significantly correlated with the volume of specimen, preop BMI, LSM, and CAP of transient elastography (p<0.001)
CONCLUSION: NAFLD is related with higher BMI and these patients also have larger gastric volume and higher gastric expansibility. By measuring the sleeve gastrectomy specimen we can fairly estimate the degree of hepatosteatosis or NAFLD.
