Abstract
BACKGROUND
Aortoduodenal fistula (ADF) managed with duodenal stenting has never before been reported in the literature.
CASE SUMMARY
A 75-year-old Chinese female with metastatic ureteric carcinoma presented with massive gastrointestinal bleeding secondary to ADF. Initial haemorrhage was managed with endovascular aortic repair and endoscopic haemostasis. However, she refused definitive open surgery. Her duodenal fistula was managed with partially covered stenting of the duodenum, which was complicated with duodenal stent migration. The duodenal stent was removed and replaced, and fixed in place with endoclips. She tolerated oral feeding until she passed away two months later.
CONCLUSION
This case report demonstrates that combined endoscopic and endovascular management of ADF can be feasible in selected patients.
Core Tip: Aorto-duodenal fistula is a rare cause of gastrointestinal bleeding and most commonly managed with open surgery. This case reports the first ever use of minimally invasive treatment of aortoduodenal fistula with endovascular repair of aorta and endoscopic stenting of duodenum. The duodenal stent was complicated with migration, which can be prevented with clipping of the duodenal stent to the mucosa.
