Clinical Trial Summary

Prospective non-randomized intervention case control study on patients with a BMI > 35. The intervention group/cases (n=600) is comprised of bariatric patients who undergo bariatric surgery and the control group (n=600) of age, weight and comorbidity matched patients who choose not to undergo bariatric surgery. The overall aim is to examine prevalence of the spectrum of fatty liver disease (NAFLD) in these patients and the prognostic significance of NAFLD.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants who will die during the follow up period in case and control group	Difference in mortality between cases and controls with various NAFLD severity on biopsy.	10 years follow up after inclusion
Secondary	Number of participant who will experience progressive fatty liver disease in case and control group	Difference NAFLD severity between case and control group after 10 years follow up. Simple steatosis is the mildest form and liver cirrhosis is the most serious manifestation: Grade 1 steatosis; Grade 2 steatosis; Grade 3 steatosis; Non alcoholic steatohepatitis; Presence of fibrosis Kleiner grade 1-2; Presence of fibrosis Kleiner grade 3; Presence of liver cirrhosis	10 years follow up after inclusion
Secondary	Change in continuous reaction time measurement after bariatric surgery	Continuous reaction time measurement will measure reaction time instability and is a measure of metabolic encephalopathy. The method is a 10-minutes, computerised registration of a series of motor reaction times to an auditory stimulus, with results reported as the CRTindex (50 percentile/(90-10) percentile) as a parameter of reaction time variability. A CRT index below 1.9 i considerede abnormal a may be a sign of hepatic encephalopathy.	10 years follow up after inclusion
Secondary	Change in EEG after bariatric surgery	Change in mean dominant frequency(MD) on EEG spectral analysis. EEG disturbances in hepatic encephalopathy are (rated by severity)but there is no enough space here to describe it.	24 months after surgery
Secondary	Change in intelligence quotient after bariatric surgery	Measured by Weschlers adult intelligence scale (WAIS). An IQ if 100 i the norm. Range 50-150.	24 months efter surgery
