Comparison of 5‑Year Follow‑up Outcomes Between Primary and Revision Roux‑en‑Y Gastric Bypasses After Open Vertical Banded Gastroplasty: an Inverse Propensity Score‑Weighted Analysis

This study compared the 5-year follow-up outcomes of primary Roux-En-Y Gastric Bypass (PRYGB) and revision RYGB after Vertical Banded Gastroplasty (RRYGB). RRYGB in patients with Vertical Banded Gastroplasty (VBG) who regained weight showed comparable safety and resolution of associated diseases to that of PRYGB over the 5-year follow-up period. The Weight Loss in the RRYGB group was acceptable despite being less than that of the PRYGB group. Food Tolerance was better after RRYGB than that of PRYGB in the first year; however, both were comparable at the fifth year follow-up. Patients with VBG undergoing RYGB should receive attentive treatment and evaluation of associated factors.
