Supplementary Material for: Treatment of Gastrointestinal Bleeding in the Biliopancreatic Limb with Embolization in a Patient with Duodenal Switch Anatomy

Introduction: Biliopancreatic diversion with duodenal switch (BPD/DS) is an uncommon type of bariatric surgery that can rarely lead to bleeding in the biliopancreatic limb. The altered anatomy poses significant diagnostic and therapeutic challenges. Case presentation: We present an unusual case of a woman status post BPD/DS nearly a decade ago who presented with gastrointestinal bleeding in the duodenum of the biliopancreatic limb, a rare phenomenon given the unique surgery. Conclusion: We illustrate a promising minimally invasive option of successfully treating the bleeding by interventional radiology (IR) embolization as an alternative to more invasive and challenging options of balloon-assisted enteroscopy, lumen opposing metal stent (LAMS) placement and surgical intraoperative enteroscopy.
