Abstract
OBJECTIVE To confirm the advantage of in situ reconstruction (ISR) over extra-anatomic reconstruction (EAR) for aortic graft infection and determine the most appropriate conduit including autogenous veins, cryopreserved allografts, and synthetic prosthesis (standard, rifampicin of silver polyesters). METHODS A meta-analysis was conducted with rate of mortality, graft occlusion, amputation, and reinfection. A meta-regression was performed with 4 factors: patients' age, presence of prosthetic-duodenal fistula (PDF), virulent organisms, or nonvirulent organisms. RESULTS In situ reconstruction over EAR seems to favor all events. For the 5 conduits used for ISR, according to operative mortality, age of the patients looks to have a positive correlation only for silver polyester and no conduit present any advantage in the presence of PDF. Reinfection seems to be not significantly different for the 5 conduits, and only autogenous veins appear to have a positive correlation with infecting organisms. CONCLUSION In situ reconstruction may be considered as first-line treatment. Our results suggest that silver polyesters appear to be most appropriate for older patients, and in order to limit reinfection, autogenous veins are probably the most suitable conduit.

Abstract
Upper gastrointestinal (GI) bleeding is an important clinical condition managed routinely by endoscopists. Diagnostic and therapeutic options vary immensely based on the source of bleeding and it is important for the gastroenterologist to be cognizant of both common and uncommon etiologies. The focus of this article is to highlight and discuss unusual sources of upper GI bleeding, with a particular emphasis on both the clinical and endoscopic features to help diagnose and treat these atypical causes of bleeding.

Abstract
Gastrointestinal (GI) bleed often brings the patient to the emergency medical service with great anxiety. Known common causes of GI bleed include ulcers, varices, Mallory-Weiss among others. All causes of GI bleed should be considered however unusual during the evaluation. Aortoenteric fistula (AEF) is one of the unusual causes of GI bleed, which has to be considered especially in patients with a history of abdominal surgery in general and aortic surgery in particular.

Abstract
Aortic aneurysms and stenosis occurring in Takayasu arteritis may require aortic prosthesis that can be complicated by aorto-digestive fistula. We report a 41-year-old female who presented with an isolated abdominal pain revealing a para-prosthetic aorto-duodenal fistula complicating a Takayasu arteritis. The diagnosis of aorto-digestive fistula may be difficult if abdominal pain is isolated and imaging inconclusive. Surgical procedure may be necessary to obtain the diagnosis and constitutes the main part of the treatment before fatal outcome.

Abstract
A 61-year-old man was admitted to hospital due to recurrent upper gastrointestinal bleeding. Four weeks ago, he had been treated with epinephrine and endoclips by endoscopy due to an arterial gastrointestinal bleeding. The patient had a history of coronary and peripheral artery disease, diabetes, and an abdominal aortic aneurysm. Urgent endoscopy suggested the presence of an ulcus Dieulafoy but no definitive bleeding source could be seen. Due to ongoing melena an abdominal computer tomography was performed and a primary aortoduodenal fistula was suspected caused by the infrarenal abdominal aortic aneurysm. Laparatomy was undertaken emergently and an aortoduodenal fistula was found in the descending part of the duodenum. Repair of the duodenal rent was performed and the aortic aneurysm was replaced by a Dacron prosthesis. The patient was transferred to the intensive care unit. 4 days after initial admission, he died due to septic shock.

Abstract
Present knowledge on natural history and how to treat penetrating aortic ulcers or different forms of pseudoaneurysms with or without infection is limited as there are only case reports and small series of unusual aortic pathology and its treatment available. Material: From our centre we collected 65 patients treated with open (n=15) or endovascular reconstruction (n=50) during a 20-year period in the abdominal aorta. These patients are presented including a review of contemporary treatment. Results: Endovascular reconstructions seem to reduce morbidity and mortality compared to otherwise extensive open surgery. Even for patients with infectious etiology (mycotic aneurysms, aorto-enteric fistula) endovascular treatment may be a first-hand option bridging to a more elective open repair. However, a large proportion of patients being unfit for further open surgery were solely treated endovascularly and had no major infectious complications in the follow-up. Registers of cases with unusual aortic pathology, not only of those treated but also of those managed conservatively, are needed to define who to treat and if endovascular or open repair should be recommended. Conclusion: Endovascular technique is a promising technique for treatment of aortic pseudoaneurysms of different etiologies. We firmly recommend, despite the lack of evidence, that the work up of patients with penetrating aortic ulcers, mycotic or other types of pseudoanerysms as well as aorto-enteric fistulae should enclose both endovascular and open (or combined) treatment modalities. However, our knowledge of the natural history is limited. Therefore, registers of cases with unusual aortic pathology, not only of those treated but also of those managed conservatively, are needed to define who to treat and if endovascular or open repair should be recommended.

Abstract
Gastrointestinal bleeding affects a substantial number of elderly people and is a frequent indication for hospitalization. Bleeding can originate from either the upper or lower gastrointestinal tract, and patients with gastrointestinal bleeding present with a range of symptoms. In the elderly, the nature, severity, and outcome of bleeding are influenced by the presence of medical comorbidities and the use of antiplatelet medication. This Review discusses trends in the epidemiology and outcome of gastrointestinal bleeding in elderly patients. Specific causes of upper and lower gastrointestinal bleeding are discussed, and recommendations for approaches to endoscopic diagnosis and therapy are given.

Abstract
We performed a systematic review of the literature on the diagnosis and treatment of secondary aortoenteric fistulas (AEF). A MEDLINE search was performed of articles published in English or Spanish between January 1991 and August 2006. Diagnostic methods, treatment modalities and the results of surgical treatment were analyzed. The most frequent first aortic surgery associated with AEF was repair of abdominal aortic aneurysm (54.31%). The most common form of presentation was gastrointestinal bleeding. Repair through in situ prosthetic replacement had the lowest early mortality rates (8-13.3%) compared with graft excision and extraanatomic revascularization (18.2-44%). AEF is a serious entity and diagnosis requires a high index of suspicion based on clinical findings and indirect data from imaging techniques (computed tomography). The most appropriate therapeutic option continues to be controversial.

Abstract
BACKGROUND Aortoduodenal fistulas are rare and severe complications of aortic prostheses. The clinical picture usually includes digestive features and fever, unlike our observation where fistula was revealed by heavy and swollen leg with cutaneous septic abscesses but no digestive signs. PATIENTS AND METHODS A 59 year-old man who had undergone aortoiliac prosthetic repair of an aortic aneurysm 6 years earlier was hospitalized in a dermatology department for fever beginning three months previously associated with a heavy and swollen leg. Clinical and ultrasound examination revealed vascularised cutaneous nodules on the leg. Abdominal CAT showed left iliac venous compression caused by periprosthetic inflammation and particularly retroperitoneal fluid accumulation, gas bubbles in which suggested aortoduodenal fistula, which was confirmed during surgery. Aspirative puncture of abscesses was positive for E. Coli and Candida Glabatra. DISCUSSION Aortoduodenal fistula is a rare complication of vascular prostheses. Clinical features include digestive symptoms and fever. However, diagnosis may be difficult and delay surgery. Cutaneous manifestations appear later and are often associated with other symptoms; they are caused by septic emboli or vascular compression. Imaging methods may assist diagnosis, but surgical procedures provide confirmation and form the cornerstone of management.

Abstract
The incidence of aorto-enteric fistula in the first 5 years after abdominal aortic replacement ranges from 0.3 to 2%. We present a clinical case in which all conventional diagnostic tools failed to demonstrate the aorto-enteric fistula. A 73 year-old male suffering intermittent episodes of melena without signs and symptoms of infection was repeatedly admitted at our institution. All conventional diagnostic tools failed to show the bleeding source. Precise diagnosis was obtained using intra vascular ultrasound (IVUS). IVUS allowed prompt diagnosis of the aorto-duodenal fistula and opened the way to its endovascular treatment.

Abstract
BACKGROUND Aortoenteric fistulas (AEFs) are a rare but often fatal cause of gastrointestinal bleeding. Operative repair of AEF has been historically associated with extremely high morbidity and mortality. We reviewed our experience of open surgical and endovascular treatment of AEF to compare outcomes over a contemporaneous time period. METHODS Over a 9-year period between January 1997 and January 2006, 16 patients (11 men and 5 women) were diagnosed with and treated for AEFs. Seven patients underwent open surgical repair, and nine, with anatomically suitable lesions, underwent endovascular repair. The outcome after treatment of these patients was investigated for survival, perioperative complications, length of hospital stay, and long-term disposition. RESULTS Three primary and 13 secondary AEFs were treated. The mean time from the initial aortic operation until AEF diagnosis was 5.9 years (range, 0.7-12.2 years) for patients with secondary AEFs. The overall 30-day mortality rate was 18.8%. One intraoperative death and one in-hospital death secondary to multisystem organ failure occurred in patients undergoing open repair. One in-hospital death related to persistent sepsis occurred in the endovascular group. The overall perioperative complication rate was 50.0%. Complications in the open group included sepsis, renal failure, bowel obstruction, and pancreatitis. Complications in the endovascular group were related to persistent sepsis. The mean in-hospital length of stay was significantly longer for patients undergoing open repair compared with endovascular repair (44.0 vs 19.4 days; P = .04). Four (80%) of five patients who were discharged from the hospital in the open group were placed in skilled nursing facilities, and seven (87.5%) of eight patients discharged in the endovascular group returned home. The median overall survival after hospital discharge was 23.1 months. There were no late aneurysm-related deaths or late deaths related to septic complications. CONCLUSIONS Patients with AEFs have limited overall survival. Endovascular therapy offers an alternative to open surgical repair, seems to be associated with decreased perioperative morbidity and mortality and a shorter in-hospital stay, and allows for acceptable survival given the presence of coexisting medical comorbidities. Furthermore, endovascular repair provides a therapeutic option to control bleeding and allow for continued intervention in a stabilized setting.

Abstract
BACKGROUND Traditionally treatment of aorto-enteric fistulae involved placement of an extra-anatomic bypass and graft excision. This is associated with limb loss (10-40%) and high mortality (10-70%). More recently in situ revascularisation has been advocated. AIMS To examine our experience with the changing management of aorto-enteric fistulae over a 22-year period. METHODS Demographic, clinical, operative and pathological data were recorded retrospectively. RESULTS Twenty-one patients were included. Seven had primary fistulae. Six died prior to intervention. Five had an extra-anatomical bypass (60% mortality, 40% limb loss), four had in-situ revascularisation (25% mortality), four had a primary repair (25% mortality) and two had insertion of a tube graft (primary fistulae). The overall survival rate was 38%. The postoperative survival rate was 6o%. CONCLUSION Techniques for operative management continue to evolve. The current trend is towards a local surgical approach with prolonged and intensive postoperative antimicrobial therapy. In our experience this approach has yielded acceptable outcomes.

Abstract
Iliac-ureteral fistulas (IUF) are a rare but potential life threatening event and an important cause of gross hematuria. We report on three cases of IUF. In all cases, prior chronic ureteral stenting, extended pelvic surgery or pelvic irradiation had been performed. Diagnosis was confirmed with angiography in one case, in the others a CT scan revealed the IUF. Treatment included surgical exploration with local reconstruction, extra-anatomical bypass and nephrectomy with arterial patch repair. The increasing incidence of IUF is a consequence of an increasing number of advanced and extended pelvic operations, radiation therapy and long-term ureteral stenting. Diagnosis should be made by provocative angiography or CT. Treatment options vary depending on the site and morphology of the local situation, but morbidity and mortality is still high due to delayed adequate diagnosis and treatment. A conclusive algorithm should be followed for the successful management of IUF.

Abstract
Secondary aortoenteric fistulas (AEFs) are a well-known but uncommon cause of gastrointestinal hemorrhage. They usually occur secondary to reconstructive surgery of an abdominal aneurysm. We report six cases of secondary aortoduodenal fistulas, involving patients who, despite presenting with classic "herald bleeding," died as a result of delayed operative intervention. We also discuss the pathogenesis, clinical presentation, and diagnosis of AEFs, emphasizing the value of clinical suspicion and negative endoscopy in establishing the diagnosis and the need for early operative intervention.

Abstract
PURPOSE: To study whether endarterectomy is feasible in all patients with aortofemoral atherosclerotic obstruction, considering early and late results. METHODS: A clinical, prospective, and descriptive study carried out in a university hospital. Inclusion criteria were atherosclerotic aortofemoral obstructive disease, clinical status compatible with major surgery, and absence of prior restorative procedure. Exclusion criteria were aneurysm, inflammatory arterial disease, and prior restorative procedure found during surgery. Eighty patients entered the protocol, but 9 were excluded (11.2%). Seventy-one patients, mean age of 57.3 years, underwent endarterectomy. Operative indications were intermittent claudication and critical ischemia. A ring-stripper endarterectomy technique was employed in all patients. Results were related to age, gender, symptoms, presence of diabetes mellitus, extension of endarterectomy, and extent of obstructive disease. Chi square or Fisher exact tests were used when appropriate, and the Wilkoxon (Gehan) test was used to compare survival curves. RESULTS: Sixty-eight (100%) endarterectomies were patent at discharge. The mortality rate was 4.2%. The amputation rate (4.3%) was higher in diabetic patients and when there was associated femoropopliteal obstruction. The 5-year survival rate was 83.3%, and late deaths were mostly cardiovascular. Diabetes mellitus, age above 65 years, and associated femoropopliteal obstruction lowered the survival rate. The 5-year patency rate was 87.0%. Critical ischemia and less extensive endarterectomies were associated with a lower patency rate. There were no anastomotic aneurysms or deep infections. CONCLUSIONS: Aortofemoral thromboendarterectomy is feasible in 90% of patients, early mortality rate is low, diabetic patients and those with associated femoropopliteal obstructive disease have a higher mortality rate, amputation rate is low, late deaths are mostly cardiovascular, and late patency rate is high, and even higher in the intermittent claudication group.

Abstract
OBJECTIVE To review published reports on arterio-ureteral fistula. METHOD Literature search. RESULTS Eighty cases were identified. Primary fistulas were mainly seen in combination with aortoiliac aneurysmal disease. Secondary fistulas were seen after pelvic cancer surgery, often with radiation, fibrosis and ureteral stenting or after vascular surgery with synthetic grafting. The dominating symptom is massive haematuria, often with circulatory impairment. The clue to a rapid and correct diagnosis is a high degree of suspicion. Most frequently diagnosis has been obtained through angiography or pyelography. When there is a ureteral stent manipulation it will often provoke bleeding and lead to diagnosis. The fistula must be excluded and a vascular reconstruction made. Most frequently this has been obtained through occlusion of the fistula and an extra-anatomic reconstruction (femoro-femoral crossover). Recently stent-grafting has been successfully used but follow-up is short. CONCLUSION Arterio-ureteral fistula is rare and should be suspected in patients with complicated pelvic surgery and massive haematuria, especially where rigid ureteral stents have been placed.

Abstract
PURPOSE Aortoduodenal fistulas are the most frequent aortoenteric fistulas. They may be primary (occurring after aneurysms of the native aorta) or secondary (occurring after aortic prosthesis). Aortoduodenal fistulas are a rare complication of aortic prostheses. They may be caused by prosthesis infection or due to inadequate prosthesis. METHODS We report seven observations that emphasize issues pertaining to either diagnosis or therapy. RESULTS The delay of occurrence is variable, with a mean of 3 years as reported in the literature. Clinical picture includes upper digestive tract hemorrhage, sometimes fever, abdominal pain or mass. Though difficult, diagnosis can be achieved through gastric endoscopy or CT-scan. Additional diagnostic procedures are often not useful and should not be numerous. Surgical procedures help guide the diagnosis and constitute the main part of the treatment with suture of the duodenum and vascular prosthesis. According to previous works, our observations including prolonged follow-up of the patients suggest that the best vascular treatment is extra-anatomic axillo-bifemoral bypass, while simple suture and prosthesis replacement lead to poor results. CONCLUSION Mortality related to aortodigestive fistulas is high (five out of seven patients in the present study) and requires prevention, including more particularly delicate surgery and antibiotic therapy in case of any episode of infection. Aortoduodenal fistulas must be suspected whenever a patient with aortic prosthesis has digestive bleeding or unexplained fever.
