Vascular covered stent and video-assisted thoracoscopic surgery for Aortoesophageal fistula caused by esophageal fishbone: a case report.

BACKGROUND: Aortoesophageal fistula (AEF) is a rare condition characterized by communication between the aorta and esophagus. AEF caused by an esophageal foreign body is even rare, and there is currently no recommended standard treatment protocol. We report a case of delayed aortic rupture after the endoscopic removal of a fish bone, which was successfully treated with a combined approach of vascular stenting and thoracic surgery. CASE PRESENTATION: A 33-year-old man presented to the hospital after experiencing chest discomfort for 3 days following the accidental ingestion of a fish bone. Under endoscopic guidance, the fish bone was successfully removed, and the patient was subsequently admitted for medical therapy. On the fourth postoperative day, the patient suddenly developed hematemesis, and chest computed tomography angiography revealed the presence of an AEF. This necessitated urgent intervention; hence, thoracic surgery was performed and a vascular-covered stent was placed. Following the surgical procedure, the patient received active medical treatment, recovered well, and was successfully discharged from the hospital. CONCLUSIONS: In patients with esophageal perforation caused by foreign bodies, hospitalization for observation, computed tomography angiography examination, early use of antibiotics, and careful assessment of aortic damage are advised. Thoracic endovascular aortic repair and esophageal rupture repair may have benefits for the treatment of AEF.

A successful endovascular aortic repair of aortoesophageal fistula following esophagectomy: a case report and literature review.

BACKGROUND: Aortoesophageal fistula (AEF) is an extremely rare and highly fatal complication leading to a high risk of morbidity and mortality. Successful management of AEF after esophagectomy for esophageal carcinoma has rarely been reported in the literature. CASE PRESENTATION: Here we present a rare case of a 44-year-old female with complications of AEF after esophagectomy for esophageal carcinoma, mainly presented as vomiting of blood. Both computed tomographic and computed tomography angiography of the chest showed bilateral pleural effusion and atelectasis, while gastroscopy showed large gastrointestinal bleeding. Emergency surgery was performed that included the removal of the mediastinal abscess, left lower pulmonary wedge resection, and thoracic endovascular aortic repair (TEVAR), followed by supportive treatment. The surgery went successful, and the patient was followed up for 1 year after discharge and showed good recovery. We also reviewed previous literature on the history, causes, pathophysiology, clinical presentation, diagnosis, and treatment of AEF after esophagectomy for esophageal adenocarcinoma. CONCLUSIONS: In our case, thoracotomy combined with TEVAR was effective in treating AEF after esophagectomy for esophageal adenocarcinoma. This case provides successful experiences for clinical diagnosis and treatment of AEF after esophagectomy for esophageal carcinoma.

Multifaceted surgical approach of combined thoracoretroperitoneal incision and midline abdominal incision for a secondary aortoenteric fistula.

BACKGROUND: We report a one-stage surgery to the case of secondary aortoenteric fistula (sAEF) after prosthetic reconstruction of abdominal aortic aneurysm, by multifaceted approach. CASE PRESENTATION: A 63-year-old male was admitted to our unit under diagnosed of sAEF after prosthetic reconstruction of abdominal aortic aneurysm, and a pseudoaneurysm of thoracoabdominal aorta due to infection. The patient underwent emergency operation. Firstly, we placed the patient in a modified right lateral decubitus position and performed thoracoabdominal aortic replacement with retroperitoneal approach by thoracoretroperitoneal incision which combined thoracotomy and pararectal incision, and secondly, we changed to a supine position and performed closure of the duodenal fistula and omental flap transposition by midline abdominal incision. The patient was doing well without complications. CONCLUSIONS: A one-stage, multifaceted surgical approach covering both prosthetic reconstruction of thoracoabdominal aorta and closure of sAEF with omentopexy is reasonable and useful strategy.

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.

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.

Aortoesophageal fistula treated using one-stage total reconstruction: a case report from a high-volume center.

BACKGROUND: Aortoesophageal fistula (AEF) is a rare but typically life-threatening condition. Although several treatment strategies exist, including conservative treatment with intraluminal stent graft and open thoracic aortic replacement, the overall outcome remains poor, ranging from 16 to 39%. Furthermore, esophageal reconstruction methods vary between hospitals. Herein, we report a case of aortoesophageal fistula treated using one-stage total reconstruction. CASE PRESENTATION: This case involved a 58-year-old woman who developed acute type A aortic dissection and underwent successful total arch replacement at the other hospital. However, she developed AEF 1 year later and underwent urgent thoracic endovascular aortic repair, which eventually failed. We performed thoracic aortic replacement, total esophagectomy, gastric tube reconstruction, and omental flap in a one-stage operation. The patient was extubated the next day and transferred to the general ward on postoperative day 3. Computed tomography revealed favorable results. CONCLUSIONS: For postoperative AEF, dedicated debridement with reconstruction is more effective than conservative treatment. In an experienced center, post-procedure-related AEF can be easily treated using one-stage reconstruction.

Who needs their descending thoracic aorta anyway? Extra-anatomic bypass for aorto-bronchial fistula after TEVAR.

BACKGROUND: Aortobronchial fistula after TEVAR remains a vexing clinical problem associated with high mortality. Although a combination of endovascular and open surgical strategies have been reported in managing this pathology, there is as yet no definitive treatment algorithm that can be used for all patients. We discuss our approach to an aortobronchial fistula associated with an overtly infected aortic endograft. CASE PRESENTATION: A 49-year-old female sustained a traumatic aortic transection 14 years prior, managed by an endovascular stent-graft. Due to persistent endoleak, she underwent open replacement of her descending thoracic aorta 4 years later. Ten years after her open aortic surgery, the patient presented with hemoptysis, and a pseudoaneurysm at her distal aortic suture line was identified on computed tomography, whereupon she underwent placement of an endograft. Eight weeks later, she presented with dyspnea, recurrent hemoptysis, malaise and fever, with clinical and radiographic evidence of an aortobronchial communication and an infected aortic stent-graft. The patient underwent management via a two-stage open surgical approach, constituting an extra-anatomic bypass from her ascending aorta to distal descending aorta and subsequent radical excision of her descending aorta with all associated infected prosthetic material and repair of the airway. CONCLUSION: Aortobronchial fistula after TEVAR represents a challenging complex clinical scenario. Extra-anatomic aortic bypass followed by radical debridement of all contaminated tissue may provide the best option for durable longer-term outcomes.

Staged Repair of Primary Aortoesophageal Fistula.

Primary aortoenteric fistulas are rare with an incidence reported up to .07% at autopsy. Literature review yields few reported cases, and rarer still is a fistula between a normal thoracic aorta and the esophagus. Rather, 83% of cases are associated with an aneurysmal aorta and 54% involve the duodenum. Patients with aortoesophageal fistula (AEF) usually present with a triad of chest pain, dysphasia, and a herald bleed. Without treatment, AEFs will result in exsanguination and are universally fatal; even with traditional open surgical treatment, mortality is reported over 55%. The complex pathology of AEFs makes repair more challenging, given an infected field, friable tissue, and patients who are often hemodynamically unstable. Staged repair using endografts as initial treatment with the primary goal of controlling bleeding and preventing fatal exsanguination has been reported. We present a case where a descending thoracic aorta to esophageal fistula was repaired, and this strategy was utilized.

Colorectal Malignancy Complicated by Arterioenteric Fistula.

Arterioenteric fistulas (AEF) are rare and devastating complications of colorectal/pelvic malignancies. These fistulas can be seen following neoadjuvant or adjuvant therapy but are exceptionally rare de novo. The reported incidence of AEF is less than 1% and iliac artery-enteric fistulas make up less than .1% of all AEF. Here we present a patient in hemorrhagic shock secondary to an advanced colorectal malignancy without adjuvant therapies with local invasion of the right external iliac artery. Following initial resuscitation and hemorrhage control with coil embolization, definitive control with ligation and excision of the involved artery, end colostomy, and ureteral stent placement was achieved. It is important to consider malignancy as the source of lower gastrointestinal bleeds, especially in elderly patients without current colonoscopy studies. The management of this unfortunate diagnosis often involves a multidisciplinary approach with early and frequent goals of care discussions.

Successful Medical Treatment for Aortoesophageal Fistula after Thoracic Endovascular Aortic Repair.

Aortoesophageal fistula is a fatal disease that requires surgical treatment. Due to the patient's wishes, we chose medical treatment for aortoesophageal fistula after thoracic endovascular aortic repair for a pseudoaneurysm in the distal anastomotic site after total aortic arch replacement. Satisfactory early and long-term outcomes were obtained with complete fasting and appropriate antibiotics.

[Uretero-iliac artery fistula as a urological emergency]. / Ureteroiliakale Fistel als eine Urologische Notfallsituation.

Uretero-iliac artery fistulae represent a urological emergency with considerable mortality. We present 2 cases of a uretero-iliac artery fistula. Nowadays, minimally-invasive endovascular therapy seems to be the treatment of choice. For an optimal outcome, a multidisciplinary team with imminent availability of radiology, vascular surgery, urology and anaesthesia is required.

Lessons learned in aortoenteric fistula repair: a multidisciplinary team approach and diagnostic-therapeutic algorithm matter.

Aortoenteric fistula (AEF) is a low-prevalence, life-threatening condition regardless of treatment, with a 30-50% postoperative (≤60 days) mortality. This study aimed to estimate our postoperative cumulative mortality incidence and assess the feasibility of the diagnostic-therapeutic algorithm used in our clinical practice. We performed a retrospective cohort study of patients treated for AEF at a fully-equipped tertiary healthcare center between January 2008 and December 2020.

[Aortoesophageal Fistula Induced by an Indwelling Nasogastric Tube: A Case Report].

A 91-year-old woman who presented with melena and hypovolemic shock visited the emergency room. She received enteral nutrition by nasogastric tube in a bedridden state due to hip surgery. Gastroscopy initially suggested a simple ulcer that occurred after a nasogastric tube was placed for a long time, but the ulcer was deep, and the amount of instantaneous bleeding was considerable. Therefore, an aortoesophageal fistula was suspected. Angiography was performed instead of endoscopic hemostasis, followed by thoracic endovascular aortic repair (TEVAR). After the TEVAR procedure, the patient recovered without further gastrointestinal bleeding. Prompt judgment and communication between the endoscopist and the interventional physician are important for successful hemostasis in an aortoenteric fistula patient.

Too big to fail?-An aggressive strategy for a dire problem.

Tracheo-innominate fistula (TIF) is a reported complication of tracheostomy that typically presents with a herald bleed. The phenomenon of an aortotracheal fistula has similar pathology and presentation to TIF, but no standard surgical repair. In the manuscript by Musgrove et al. in the Journal of Cardiac Surgery, the authors propose a surgical treatment that is reproducible for the correct anatomic configuration-an ascending and aortic arch replacement, pericardial patch of the tracheal defect, and omental flap coverage. While this intervention is a large undertaking for a small defect, it is a safe and durable repair.

Esophago-aortic fistula of esophageal cancer after chemotherapy, proton therapy and salvage photodynamic therapy: a rescued case.

We describe a case of esophageal cancer after proton therapy that resulted in an esophagoaortic fistula after photodynamic therapy (PDT). A 49-year-old woman with esophageal cancer (cT1bN0M0, cStage I) underwent chemotherapy (5-FU and cisplatin) and radiotherapy (proton therapy to the cancer lesion after X-ray radiotherapy to the regional lymph nodes). Despite a complete response of the primary tumor, local recurrence was observed 10 months after treatment. PDT was performed as a salvage treatment. She was transported to the emergency department in a state of hemorrhagic shock due to hematemesis 50 days after PDT. We diagnosed an esophagoaortic fistula caused by esophageal perforation, and resuscitative endovascular balloon occlusion of the aorta and thoracic endovascular aortic repair were performed. The patient was successfully rescued after three surgeries (esophagectomy, extraesophageal fistula, aortic vascular replacement, and gastrointestinal reconstruction). In addition to X-ray radiotherapy before photodynamic therapy, proton therapy in combination with the vascular shutdown effects of PDT may have caused ischemia of the esophagus, resulting in an esophagoaortic fistula. When performing PDT, the type of radiation therapy and the location of the lesion should be examined to assess the risk of penetration or perforation.
