Abstract
Despite the safety and efficacy of Roux-en-Y gastric bypass (RYGB), a subset of patients (<1%) requires RYGB reversal. This reestablishes continuity between the pouch and bypassed stomach after resecting the gastrojejunostomy. Whether the alimentary limb is reconnected or discarded depends on clinical findings. The most common indications for reversal include excessive weight loss, neuroglycopenia and refractory marginal ulceration. In rare cases, RYGB reversal is required in the emergent setting. We present 3 cases of emergent RYGB reversal for ischemic complications of internal hernia and need for safe and rapid assurance of GI continuity.
