Laparoscopic Sleeve Gastrectomy on the Horizon as a Promising Treatment Modality for NAFLD

Nonalcoholic fatty liver disease (NAFLD) is viewed as the hepatic manifestation of the metabolic syndrome with hepatic fatty infiltration is the common liver pathology. NAFLD can lead to nonalcoholic steatohepatitis (NASH), liver cirrhosis, liver cell failure, and liver malignancy.The present work aims to prospectively study the histological changes that occur in NAFLD obese patients 1-year post-laparoscopic sleeve gastrectomy (LSG) based on standardized NAS (NAFLD activity score).
This prospective study included 94 obese patients who underwent laparoscopic sleeve gastrectomy. Intraoperative wedge liver biopsy was taken from all patients with a follow-up liver biopsy at 12 months after the operation.
LSG produced a marked reduction in body weight with a mean reduction in BMI from 44.54 + 5.45 to 34.23 + 2.66 kg/m2 at 12 months. There were statistically highly significant improvements regarding metabolic comorbidities, blood pressure, lipid profile, and HbA1C at 12-month post-LSG (P < 0.001). The current study showed a highly statistically significant improvement at 1-year post LSG regarding steatosis grade, hepatocyte ballooning, lobular inflammation as well as fibrosis stage (P < 0.001). Moreover, the present study showed that NAS score significantly decreased from 5.20 + 1.96 at baseline to 2.63 + 1.55 at 1-year follow-up (P < 0.001).
Our relatively large patient cohort shows a significant improvement of steatosis, steatohepatitis, and fibrosis at a 1-year follow-up. LSG can lead to resolution of NAFLD, and it may be in the near future another routine indication for bariatric surgery.
