Why carry out the study?

To evaluate whether the extent of gastrectomy or the reconstruction method brings benefit of T2MD remission after gastrectomy in patients with gastric cancer.

What was learned from the study?

Total gastrectomy with R-Y reconstruction had an advantage over other surgical methods in terms of T2MD remission, but there was no difference between subtotal gastrectomy with R-Y and with non-R-Y (Billroth I and Billroth II) reconstruction in terms of T2MD remission.

Total gastrectomy with R-Y had better T2MD remission.

The extent of gastrectomy rather than the reconstruction method might play an important role in T2MD remission after gastrectomy in patients with gastric cancer.
