BACKGROUND: Obesity-associated nonalcoholic fatty liver disease (NAFLD) is a significant cause of chronic liver disease. Our study sought to investigate preoperative NAFLD and the effect at 6 months and 2 years after surgery of one anastomosis gastric bypass (OAGB) and its development 6 months after surgery regarding weight loss outcomes.
MATERIALS AND METHODS: A retrospective cohort study was conducted on patients with severe obesity who underwent primary OAGB at Hazrat-e-Rasool Hospital between March 2020 and June 2021. Preoperative assessments included abdominal ultrasound (US) for NAFLD grading, weight, and biochemical blood tests. Follow-up examinations were performed at 10 days and 1, 3, 6, 9, 12, and 24 months postsurgery, with subsequent US examinations at the 6-month follow-up.
RESULTS: Two hundred thirty-one patients were included, with an average age of 40.3±10.5 years and a percentage of 78.4 women. Their mean weight and BMI were 131.2±26.8 and 48.8±8.5, respectively. Six-month grades of NAFLD showed that patients with grade 3 NAFLD had significantly lower TWL% compared with the lower grades. NAFLD grades improved in 72.3% of our patients, remained the same at 21.2%, and worsened at 6.5%. The 6-month TWL% was 28.4±4.3 in the no-change group, 28.4±5.3 for the improved group, and 25.2±14.6 in the worse group.
CONCLUSION: The severity and progression of NAFLD can significantly impact weight loss outcomes post-OAGB, highlighting the importance of monitoring and managing NAFLD in patients undergoing bariatric surgery.
