A simple SJA, diverting the food and biliopancreatic secretion to the distal small bowel, was able to control T2DM in all patients offering total or partial remission of the disease soon after the procedure.

However, further studies are in progress in both Institutions to reveal the possible mechanism of diabetes control and investigate the effect of this operation on larger number of patients, with longer follow-up period.
