Abstract
Introduction
Nowadays, surgeons are dealing more and more with patients experiencing failure of a previous bariatric procedure after the worldwide exponential increase of bariatric surgery. Only a few and contradictory studies investigated both outcomes and complications risk factors in this subset population of bariatric patients. We aimed to study a homogeneous population of patients undergoing redo bariatric surgery (REDO-BS) resulting in bypass anatomy to evaluate early postoperative outcomes and identify risk factors of postoperative complications and mortality.
Material and Methods
In this study, we compared the outcomes of patients undergoing REDO-BS from another former bariatric procedure into Roux-en-Y gastric bypass (RYGP) to those undergoing primary RYGP. Data were extracted from a prospectively maintained database.
Results
One hundred thirty-eight conversional bariatric surgery (CBS) cases resulting in RYGP anatomy and 38 RBS cases of pouch resizing (PR) were compared with 756 primary RYGP. There were no statistical significant difference in outcomes between the primary and CBS groups but patients undergoing PR had a significant higher risk of developing a leak than others. CBS complication risk factors were age (OR = 1.05; p = 0.04), operative time, and T2DM (OR = 4.11; p = 0.03).
Conclusions
CBS is safe and leads to similar early postoperative outcomes as primary RYGP whereas the indication for revisional surgery such as PR should be carefully evaluated as it is associated with an increased risk of leak.
