Introduction: Bariatric surgery (BS) is an effective strategy for the remission of non-alcoholic steatohepatitis (NASH) in morbidly obese (MO) patients, producing an improvement in comorbidities and better glycaemic control in patients with DM2. Liver biopsy remains the definitive test to classify a patient with NASH/NASH, however, the use of non-invasive techniques such as fibroscan would avoid the limitations and risks that biopsy can cause in this type of patient. Therefore, in this study we determined the improvement of NASH by fibroscan in patients with OM undergoing BC and classified according to diabetes (DM2).

Material and Methods: We included 38 patients with OM classified according to the presence of DM2, who underwent BC and were followed up 1 year after BC. Fibroscan was performed before surgery and one year after BC. Anthropometric and biochemical variables and liver fibrosis scores were measured.

Results: Of the 38 patients included, 22 (non-DM2), and 16 (DM2), only 7 patients remained DM2 at 1 year after BC, which meant a remission of 56.3%. BMI before and 1 year after BC were similar in the two cohorts studied. Fibroscan was also similar in both groups before surgery, reflecting a significant improvement, especially in non-diabetics, but also in diabetics after surgery.

Conclusions: According to this study, liver improvement is equal in both groups of patients after one year. It shows that elastography is a valid technique to assess NASH remission in OM patients undergoing bariatric surgery. Therefore, it is important to use fibroscan to evaluate those patients with NAFLD with liver fibrosis and to prioritise their surgical intervention over those without obesity-associated comorbidities.
