Wireless Capsule Video Endoscopy: A New Diagnostic Method for Aortoduodenal Fissure

Abstract

Figure 2 Meanwhile, wireless capsule video endoscopy was carried out to confirm the diagnosis in this patient, owing to the high risk of the intervention. Surprisingly, the wall of the small intestine in the ascending duodenum had been replaced by the Dacron prosthesis, producing the imaging appearance shown here. This unexpected finding was confirmed during open abdominal surgery. Figure 1A 66-year-old man with a history of aortobifemoral bypass 5 years previously was admitted to our hospital with abdominal pain and fever. Abdominal computed tomography (CT) was carried out, revealing the presence of gas involving the aortic prosthesis, and a large retroperitoneal abscess. Antibiotic therapy was initiated, and the abscess was drained under radiographic control. The patient was scheduled for surgical intervention 48 h later, with a suspicion of aortic-enteric fissuration. Images in Focus 938This document was downloaded for personal use only.

First Report of a Secondary Aortojejunal Fistula Visualized by Small Bowel Capsule Endoscopy

“…In view of the associated significant mortality (22-100%) [2,3], early recognition of an AEF is paramount. To the best of our knowledge, this is the first report of a jejunal AEF identified by SBCE and confirms the usefulness of capsule endoscopy in providing corroborative evidence for diagnosis [4], especially where the AEF lies beyond the duodenum. …”

Aortoduodenal Fistulas After Endovascular Stent-Graft Repair of Abdominal Aortic Aneurysms:Single-Center Experience and Review of the Literature

“…50 The use of F18-fluorodeoxyglucose-positron emission tomography/CT (FDG-PET/CT) has also been described as a potent diagnostic tool for ADF. 52 Gonzá lez-Suá rez et al 53 reported the use of wireless capsule video endoscopy for depicting an ADF.…”

Aortoduodenale Fistel als Ursache der gastrointestinalen Blutung - eine endoskopisch schwierige Differenzialdiagnose

“…In vielen Fallberichten konnte die Endoskopie die Diagnose nicht stellen [5,9,11,16]; in einer Studie von Pipinos et al wird die Sensitivität der Ösophagogastroduodenoskopie gar mit nur 25 % angegeben [17]. Zur Push-Enteroskopie und zur Doppelballon-Enteroskopie liegen keine Daten zu aortoenterischen Fisteln vor; eine Kasuistik beschreibt die mögliche Rolle der Kapselendoskopie [18]. Wegen der Problematik der endoskopischen Diagnosestellung empfehlen manche Autoren die Computertomographie als primäre diagnostische Methode [11]; Perks et al berichteten kürzlich über die computertomographische Diagnose aortointestinaler Fisteln bei 3 Patienten [18].…”
