case_images: fig1-2324709620934680
case_images: Repeat EGD was done to biopsy the fistula and pathology were consistent with poorly differentiated serous carcinoma with morphology and immune profiling consistent with the initial high-grade serous carcinoma of the ovary (Figures 1-5).
case_images: Endoscopic retrograde cholangiopancreatography showing biliary stenosis, common biliary
  duct stricture.

case_images: Repeat esophagogastroduodenoscopy (EGD) showing duodenal fistula. Second portion
  duodenum was carefully viewed using the standard EGD followed by the side-viewing
  duodenal scope: protruded major papilla with previously placed common bile duct stent
  seen extending into the duodenal lumen. A small fistula with brown, particulate fluid
  content likely bilious fluid flowing into the duodenal lumen was seen at approximately 2
  duodenal mucosal folds superior or proximal to the major papilla.

case_images: Repeat EGD was done to biopsy the fistula and pathology were consistent with poorly differentiated serous carcinoma with morphology and immune profiling consistent with the initial high-grade serous carcinoma of the ovary (Figures 1-5).
case_images: Magnetic resonance cholangiopancreatography showing fistula. Soft tissue, fluid, and
  gas collection centered within the region of the duodenum/pancreatic head with
  suggestion of communication with the common bile duct. This may reflect a duodenal ulcer
  complicated by choledochoduodenal fistula and/or abscess.
