Duodenal Ulceration Erosion Into the Common Bile Duct Status Post-Roux-en-Y Gastric Bypass: A Case Report.

ABSTRACT

Peptic ulcer disease (PUD) affects approximately four million people worldwide. The most common etiologies of PUD are Helicobacter pylori (H. pylori) infections, chronic nonsteroidal anti-inflammatory drug (NSAID) use, and smoking. A rare cause of ulcer formation is documented in patients following Roux-en-Y gastric bypass (RYGB) procedures. Delayed treatment of these ulcers can further lead to ulcer perforation, erosion of the gastroduodenal artery (GDA), and fistula formation between the biliary structures and the gastrointestinal tract. Herein, we discuss the case of a 69-year-old female with an ulcer perforation 19 years after RYGB, resulting in an atypical ulcer erosion of the common bile duct without fistula formation.
