Duodenal pulsENDO for Suboptimally Controlled Type II Diabetes Mellitus and Steatotic Liver Disease

This is a prospective, single-arm feasibility study enrolling individuals with type 2 diabetes mellitus (T2DM) who have failed to achieve adequate glycemic control with oral glucose-lowering medications. Participants will undergo the pulsENDO procedure and liver biopsies both prior to and after the procedure to evaluate its effects on metabolically associated fatty liver disease (MAFLD). They will be followed for 12 months to assess the primary endpoint and for a total of 2 years. Participants are permitted to undergo a repeat ReCET procedure once if they initially respond but experience a recurrence of suboptimal diabetes management between 1 and 2 years after the procedure. They will be followed up for an additional year after the repeated procedure.
