Massive gastrointestinal bleed due to a primary aortoenteric fistula.

A man in his 60s attended emergency for acute-onset abdominal pain and haematemesis. Requiring resuscitation, a CT abdomen/pelvis revealed a primary aortoenteric fistula actively bleeding into the duodenum. His background included a previous severe Q-fever infection and a heavy smoking history. Despite attempts at resuscitation and an emergent surgical attempt at haemostasis, the patient did not survive the massive gastrointestinal haemorrhage.Even in less severe cases, management of aortoenteric fistulas is tricky. Blood cultures and angiographic imaging are important investigations in guiding surgical approach. The pathology tends to have a significant rate of mortality even at tertiary-level vascular surgical centres.

A Rare Case of Retroperitoneal Abscess Caused by Nephro-Colic Fistula Resulting from Staghorn Calculus.

BACKGROUND Nephro-colic fistulas are uncommon, generally caused by local inflammation, trauma, or neoplasia affecting the kidney or the colon. Their association with a coralliform stone is described in a few case reports, but their management is difficult and differs quite a lot, depending on the clinical situation. We report an atypical clinical case of a reno-colic fistula associated with a staghorn calculus. This case adds to the literature an iconography rarely found. CASE REPORT A 68-year-old woman presented to the Emergency Department with respiratory symptoms and chronic abdominal pain. The biological results showed a high inflammatory syndrome. The radiological assessment revealed a retroperitoneal and left retro-renal abscess, attributed to a left nephro-colic fistula associated with the partial passage of a lithiasis within the colonic lumen. Colonoscopy confirmed the diagnosis. Multiple recurrences of diverticulitis in this region could be the origin of the complication. First, the patient was treated with antibiotic therapy and radiological drainage. Second, she benefited from a left nephrectomy, left segmental colectomy, and splenectomy. The clinical and radiological evolution were favorable after surgery. The follow-up was disrupted by hospitalizations in the Cardiology Department for cardiac decompensation. CONCLUSIONS Kidney stones along with local inflammatory phenomena can be the cause of a nephro-colic fistula. Due to the lack of guidelines in such cases, their diagnosis and management are difficult to ascertain. Surgery is the right course of treatment.

[Primary aortoduodenal fistula - a rare cause of life-threatening upper gastrointestinal bleeding]. / Primär aortoduodenal fistel.

Primary aortoduodenal fistula is a rare condition caused mainly by a bulging infra-renal aortic aneurysm with subsequent erosion of the duodenum and formation of a fistula. We present a patient who suffered from a herald upper gastrointestinal bleeding followed by circulo-respiratory collapse only hours after, due to bleeding from the fistula. The mortality is reported to be 100 %, requiring emergency EVAR or open aortic graft repair to control any further bleeding.

Treating a Bypass with Bypass Surgery: Repair of a Duodeno-sigmoid Fistula Complicating Acute Diverticulitis.

Diverticular disease is common in Western countries; one-third of patients with diverticular disease develop diverticulitis during their lifetime of whom 5% may experience serious complications. We describe a rare complication of diverticulitis: a duodeno-colic fistula in a patient with an elongated sigmoid colon (dolicosigma). The patient complained of abdominal pain, diarrhea, weight loss, and feculent vomiting. Radiological studies and gastroscopy demonstrated a fistula between the second portion of the duodenum and the sigmoid colon. Curative surgery cured the fistula and completely resolved its associated signs and symptoms.

A Modern Series of Secondary Aortoenteric Fistula - A 19-Year Experience.

OBJECTIVES: Secondary aortoenteric fistula is a rare and life-threatening condition. Clear evidence on the ideal therapeutic approach is largely missing. This study aims to analyze symptoms, etiology, risk factors, and outcomes based on procedural details. PATIENTS AND METHODS: All patients with secondary aortoenteric fistula admitted between 2003 and 2021 were included. Patient characteristics, surgical procedure details, and postoperative outcomes were analyzed. Outcomes were stratified and compared according to the urgency of operation and the procedure performed. Descriptive statistics were used. The primary endpoint was in-hospital mortality. RESULTS: A total of twentytwo patients (68% male, median age 70 years) were identified. Main symptoms were gastrointestinal bleeding, pain, and fever. From the twentytwo patients ten patients required emergency surgery and ten urgent surgery. Emergency patients were older on average (74 vs 63 years, P = .015) and had a higher risk of postoperative respiratory complications (80% vs 10%, P = .005). Primary open surgery with direct replacement of the aorta or an extra-anatomic bypass with an additional direct suture or resection of the involved bowel was performed in sixteen patients. In four patients underwent endovascular bridging treatment with the definitive approach as a second step. Other two patients died without operation (1x refusal; 1x palliative cancer history). In-hospital mortality was 27%, respectively. Compared to patients undergoing urgent surgery, those treated emergently showed significantly higher in-hospital (50% vs 0%, P = .0033) mortalities. CONCLUSION: Despite rapid diagnosis and treatment, secondary aortoenteric fistula remains a life-threatening condition with 27% in-hospital mortality, significantly increased upon emergency presentation.

Utilization of point-of-care ultrasound to evaluate for enterovesical fistula.

Enterovesical fistula formation is a relatively rare disease process although a common complication for patients with inflammatory bowel disease (IBD), notably Crohn's disease. Enterovesical fistulas most commonly arise from diverticulitis (65-80%), cancer (10-20%), or Crohn's disease (5-7%). An increasing amount of evidence supports the use of ultrasonography as the primary imaging method for the monitoring of complications in individuals with a documented history of IBD. Our case report presents a 30-year-old female with a history of Crohn's disease who presented to the Emergency Department with concern for possible enterovesical fistula formation. Using bedside gray-scale ultrasonography, a fistulous tract clearly visualizing air bubbles and fecal matter actively moving from bowel to the bladder through the fistula was visualized confirming the diagnosis of an enterovesical fistula. While CT imaging is instrumental in identifying mural and extramural complications of IBD, performing ultrasonography in patients with IBD serves as an efficient, inexpensive, and noninvasive diagnostic aid for the diagnosis of enterovesical fistula.

Revascularization and Digestive Tract Repair in Secondary Aortoenteric Fistula Using a Single-Center in Situ Revascularization Strategy.

BACKGROUND: Information regarding optimal revascularization and digestive tract repair in secondary aortoenteric fistula (sAEF) remains unclear. Thus, reporting treatment outcomes and presenting comprehensive patient details through a structured treatment approach are necessary to establish a treatment strategy for this rare, complex, and fatal condition. METHODS: We performed a single-center retrospective review of consecutive sAEF managed based on our in situ revascularization and intestinal repair strategy. The primary endpoint of this study was all-cause mortality, and secondary endpoints were the incidence of in-hospital complications and midterm reinfections. RESULTS: Between 2007 and 2020, 16 patients with sAEF, including 13 men (81%), underwent in situ revascularization and digestive tract repair. The median follow-up duration for all participants was 36 (interquartile range, 6-62) months. Among the participants, 81% (n = 13), 13% (n = 2), and 6% (n = 1) underwent aortic reconstruction with rifampin-soaked grafts, unsoaked Dacron grafts, and femoral veins, respectively. The duodenum was the most commonly involved site in enteric pathology (88%; n = 14), and 57% (n = 8) of duodenal breaks were repaired by a simple closure. Duodenum's second part-jejunum anastomosis was performed in 43% of patients (n = 6), and 19% of the patients (n = 3) died perioperatively. In-hospital complications occurred in 88% patients (n = 14), and the most frequent complication was gastrointestinal. Finally, 81% patients (n = 13) were discharged home. Oral antibiotics were administered for a median duration of 5.7 months postoperatively; subsequently, the participants were followed up carefully. Reinfection was detected in 6% of the patients (n = 1) who underwent reoperation without any complications. The 1-year and 3-year overall survival rates of participants were 75% (n = 12) and 75% (n = 9), respectively, and no sAEF-related deaths occurred, except perioperative death. CONCLUSIONS: Surgical intervention with contemporary management based on our vascular strategy and digestive tract procedure may be a durable treatment for sAEF.

Enterovesical Fistula in a Lymphoma Patient Revealed by FDG PET/CT With an Oral Contrast Agents.

ABSTRACT: A 60-year-old man with colonic diffuse large B-cell lymphoma was referred for FDG PET/CT for initial staging. He was suspected of enterovesical fistula. After oral administration, large amounts of contrast agents accumulated in the bowel lumen and leaked into the bladder through a well-marked fistulous tract. Corresponding to the fistula, a linear pattern of FDG uptake extended from the bladder into the colonic lumen, and the measured SUV max inside the lesion was as high as that of the urinary bladder. Cystography confirmed the presence of the enterovesical fistula.

Ileal conduit to small intestine fistula following extensive abdominopelvic resection and radiation for metastatic colon cancer.

A woman in her mid-60s presented with decreased output from urostomy, which was an opening from the neobladder (ileal conduit). Presentation was preceded by a 6-month history of alternating faecaluria and increased colostomy output. Laboratory studies were notable for normal anion gap metabolic acidosis. Creatinine level of the colostomy output was 17.7 mg/dL, a finding indicative of the presence of urine in the sample. CT enterography and X-ray loopogram confirmed neobladder to small intestine fistula.Neobladder creation is commonly performed in patients with bladder cancer requiring resection. Fistulas between the neobladder and intestine are observed in fewer than 2.7% of cases. The patient's history of extensive abdominopelvic resection, colostomy creation and radiation likely contributed to fistula development. We highlight the need for a high index of suspicion for a fistula in a patient with a neobladder experiencing recurrent urinary tract infections or a high colostomy output concurrently with low neobladder output.

Iatrogenic enterovesical fistula secondary to a permanent urinary catheter.

An enterovesical fistula is a rare entity resulting from inflammatory, neoplastic and iatrogenic processes. It can manifest clinically as pneumaturia and recurrent urinary tract infections. Its diagnosis is supported by imaging examinations and its treatment is primarily surgical.

Emergent Endovascular Repair For Primary Aortoenteric Fistula.

We report the case of a 64-year-old male with significant cardiac comorbidities who reported three episodes of gastrointestinal bleeding. In the third episode, he presented massive hematemesis, anaemia and hypotension. Despite a standard upper endoscopy, a computed tomography (CT) showed an infrarenal abdominal aortic aneurysm and densification of the aortic fat cover. A primary aortoenteric fistula, with acute bleeding and haemodynamic instability, was assumed, and an emergent endovascular repair was performed. Subsequent CT scans and endoscopies demonstrated control of the enteric lesion. After five months, there was no evidence of infection or rebleeding.

Unique case of colovesical fistula in a renal allograft recipient.

Colovesical fistula is commonly suspected in cases of diverticular disease, malignancy, trauma, iatrogenic injury or radiotherapy. In a case of allogenic live related transplant, this is rarely expected, especially after 20 years. The presence of gas in the bladder in the absence of history of instrumentation of urinary tract should prompt us to evaluate for colovesical fistula. Pneumaturia, faecaluria and recurrent urinary tract infection are tell-tale features of colovesical fistula, and when patients who are renal allograft recipient present with them, it should prompt a proper workup and swift surgical management, since the outcome is uniformly favourable. From our knowledge in this realm, we know that these are immunocompromised patients and have a high tendency to develop risk factors like malignancy and/or diverticular disease and eventually form colovesical fistula. An expected time period could be from 2 months to 6 years. But in our case, fistula formation occurred long after peak corticosteroid action, in the absence of conventional aetiologies.

Enteric fistulization of a common iliac vein aneurysm.

Iliac vein aneurysm is rare. Its complications include rupture, thromboembolism, and enteric fistulization. If a patient with surgical history presents with gastrointestinal bleeding, the veno-enteric fistula should be part of the differential diagnoses. In presence of a veno-enteric fistula, surgical treatment consists of aneurysmectomy, venorraphy, and intestinal resection.

Gallstone ileus, a rare cause of intestinal occlusion. A case report.

Recurrent gallstone ileus has a recurrence of 2-8.2% with a mortality of 12-20%, secondary to an enteric or cholecystic gallstone. A male patient with a diagnosis of intestinal occlusion secondary to biliary ileus and cholecystoduodenal fistula, performing enterotomy and closure in two planes with drainage placement. Two months after presenting the clinical of intestinal occlusion, medical management began and an abdominal tomography was performed, finding an image suggestive of recurrent gallstone ileus, treated with laparotomy.
