As metabolic and bariatric surgery (MBS) continues to evolve rapidly, precise and consistent procedural nomenclature is essential—not only for academic accuracy but also for safeguarding patient outcomes and ensuring research validity. In this context, we have observed a widespread confusion between sleeve gastrectomy with jejunal bypass (SG-JB) and sleeve gastrectomy with jejunoileal bypass (SG-JIB), owing to the high similarity in their terminology, in the daily practice. Although these two procedures are often grouped as “sleeve with intestinal bypass,” they differ fundamentally in anatomy, physiological effects, and postoperative risks [
