“…We selected primary repair of the enteric lesion, although no consensus has been reached regarding the optimal type of enteric repair for cases of PAEF. 20 In addition, treatment of PAEF has been associated with a high mortality rate, reaching ≤30% for in situ repair and 40% for extra-anatomic bypass. 8 Fig 5 Postoperative computed tomography scans.…”

“…AEFs that do not undergo surgical treatment are universally fatal 6, 13, 14. Chopra et al 15 found that after operative intervention, 25% of their patients died each month for the first 2 months. After 2 months, mortality rates decreased.…”
Aortoenteric fistulas are an uncommon cause of gastrointestinal bleeding, and iliac-appendiceal fistulas are an even rarer cause. We describe a case of an iliac-appendiceal fistula in a patient who presented several months after aortic reconstruction with gastrointestinal bleeding. An extensive workup revealed that the source of bleeding was localized to the appendiceal orifice. The patient underwent an appendectomy with a two-stage procedure involving the iliac graft for definitive repair and ultimately recovered well. Despite the rarity of aortoenteric and iliac-appendiceal fistulas causing gastrointestinal bleeding, keeping a high index of suspicion in patients with a prior vascular repair can prevent death.
“…Valle SJ et al reported that 5.8% of patients developed an enterocutaneous fistula after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy [25]. For an aortoenteric fistula, more than 75% involve the duodenum (aortoduodenal fistula) given its location from the graft [26]. One study reported that 0.81% of the endovascular aneurysm repair (EVAR) patients developed an aortoduodenal fistula [27].…”
