Marginal ulcer rates in primary Roux-en-Y gastric bypass versus conversion of sleeve gastrectomy to Roux-en-Y gastric bypass

No differences were observed in the rates of marginal ulceration in patients in the group who underwent primary Roux-en-Y gastric bypass surgery versus those who underwent conversion RYGB from a previous SG. This study's results contradict the results of some similar studies and challenge the hypothesis that the gastric anatomical changes after SG could possibly result in significantly compromised perfusion, thus increasing the risk of marginal ulceration. The discrepancy between our results and previous reports highlights the need for further research to clarify the underlying mechanisms and risk factors contributing to marginal ulcer development in various surgical contexts.
