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.

Esophago-pulmonary artery fistula caused by fish bone impaction.

We present a case of a 65-year-old male who experienced posterior sternal pain, accompanied by a week-long fever following the consumption of fish. Computed tomography (CT) examination revealed a fish bone in the middle esophageal, along with a small amount of gas in the mediastinum. A focal pseudoaneurysm formation was observed in the posterior wall of the left pulmonary artery trunk, accompanied by the presence of gas and septic emboli in the main trunk of the left pulmonary artery and some of its branches. Furthermore, distal pulmonary tissue infarction with associated infection was observed (Figure 1A-F). Clinical diagnosis: Esophago-pulmonary artery fistula caused by fish bone impaction. Reports of esophago-pulmonary artery fistulas without involvement of the trachea or bronchi are rare.

Fatal cerebral air embolism from atrio-oesophageal fistula following cardiac ablation.

A young woman with Rogers syndrome (thiamine-responsive megaloblastic anaemia, diabetes mellitus and sensorineural deafness) presented with headache, recurrent supraventricular tachycardia and features of an upper gastrointestinal bleed, 1 month after radiofrequency cardiac ablation for supraventricular tachycardia. She deteriorated rapidly after endoscopy and subsequently died. Brain imaging during the acute deterioration showed diffuse intracranial air embolism and hypoxic-ischaemic injury. Postmortem examination showed an atrio-oesophageal fistula, a rare complication of cardiac ablation. Clinicians should suspect this condition in patients with acute neurological deterioration after cardiac ablation who have diffuse air embolism on imaging.

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.

Management and Outcomes of Esophageal Atresia With or Without Tracheo-Esophageal Fistula Over 15 Years in South Africa.

INTRODUCTION: To determine the incidence, management and outcomes of esophageal atresia/tracheo-esophageal fistula (EA/TEF) over a 15-y period in South Africa. METHODS: A retrospective chart review of neonates with EA/TEF presenting at the main tertiary referral hospital in the KwaZulu-Natal province between 2002 and 2017 was conducted. Data collection comprised patient and maternal demographics, clinical presentations, laboratory and radiologic investigations, surgical procedures, and outcomes. A multivariate logistic regression determined the risk factors associated with mortality. RESULTS: Among 180 neonates, mean (SD) age of diagnosis was four (three) days postnatal with Gross Type C (n = 165, 92%) being the most common and the incidence was one per 10,000 live births. Majority were born term (n = 95, 53%) at peripheral hospitals (n = 167, 93%) with a mean birth weight of 2369 (736) grams. Overall HIV exposure rate was 27% (n = 48). Most (n = 138, 77%) patients presented with established pneumonia, 44% (n = 61) of whom required prolonged (>7 d) ventilator support. The median (IQR) hospital stay was 11 (8-20) d. Overall survival rate was 70% (n = 126). Birth weight <1500 g, life threatening anomalies, ventilation >30 d and postoperative sepsis contributed to mortality. CONCLUSIONS: Incidence, disease types and presentations were similar to developed countries. Despite advances in technology and neonatal care in Africa, EA/TEF surgical outcomes remain suboptimal likely due to caregivers' inability to care for these infants in disadvantaged socioeconomic circumstances with poor sanitation, etc. Research is needed to identify strategies tailored for disadvantaged communities which may contribute to improved outcomes in the perioperative and postoperative period.

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.

Hybrid stent in management of malignant airway obstruction with carina esophageal fistula: A case report.

RATIONALE: Airway stents have been developed rapidly to treat airway stenosis and fistula caused by various reasons. Malignant conditions that lead to central airway obstruction, especially the invasion of trachea carina and formation of esophageal fistula, are still a challenge for clinicians. PATIENT CONCERNS: A 61-year-old man presented with malignant airway obstruction and fistula between trachea carina and esophagus accompanied by severe respiratory failure. DIAGNOSIS: The patient was clinically diagnosed with esophageal squamous cell cancer of stage IV, carina esophageal fistula, severe pneumonia, hypoproteinemia. INTERVENTIONS: Y-shaped covered metallic stent and Y-type silicone stent (hybrid stent) were placed in the airway to increase tracheal patency, block the fistula and perform carinal plasty. OUTCOMES: The clinical symptoms of the patient improved rapidly and the lung infection was controlled effectively. This patient was followed up for more than 2 month, and the quality of life was better than before. LESSONS: Hybrid stent can be used as 1 of options for airway reconstruction and palliative treatment for patients with complex airway diseases caused by malignant tumors.

Esophageal necrosis secondary to thoracic aortic aneurysm.

We present the case of a 78-year-old man with dyslipidemia with ongoing treatment with statins. He was admitted for a history of 3-month dysphagia and weight loss. The physical exam was unremarkable. Blood tests revealed anemia (hemoglobin 11,5 g/dL). Gastroscopy showed a partially stenotic bulging ulcer in the middle esophagus, with a fibrinous base and residual clot Histopathology ruled out any malignancy and confirmed the presence of transmural necrosis with infiltration of inflammatory cells. Computed tomography (CT) revealed a 11x11x12 cm thoracic aortic aneurysm, with an intramural 4 cm thrombus in the anterolateral wall. The patient was referred for urgent Vascular Surgery, but unfortunately, he presented massive hematemesis with cardiorespiratory arrest, and despite cardiopulmonary resuscitation, he died.

Aortoesophageal fistula as a fatal complication of esophageal perforation.

Aortoesophageal fistula is a very rare cause of upper gastrointestinal bleeding, however its interest lies in the high mortality rate associated with it. Due to this, early diagnosis and treatment of this entity is essential to increase survival. The typical symptoms known as the Chiari´s triad are only present in 45% of reported cases. We present the case of a patient with upper gastrointestinal bleeding due to an aortoesophageal fistula as well as the importance of endoscopic use for its differential diagnosis.

The "airgap" and "swirling bubbles" signs in a patient with esophageal carcinoma.

INTRODUCTION: Pneumopericardium is a dreaded complication in esophageal carcinoma. CASE DESCRIPTION: We report a case of a 62 year old patient with past history of esophageal cancer with pneumopericardium, without hemodynamic compromise. Admission echocardiogram that revealed a pneumopericadium with the presence of the "swirling bubbles" and the "air gap" sign. A small esophagopericardial fistula was postulated as the cause of the pneumopericardium. He underwent esophageal stent placement with almost complete resolution of the pneumopericardium. DISCUSSION: Pneumopericardium is usually a sign of marked clinical deterioration in neoplasia and leads to patients' death few weeks. Here we presented a case, in which a more fortunate and unusual outcome happened. CASE DESCRIPTION: We present a case of a 62 year old patient, with a past history of esophageal cancer with pulmonary metastases undergoing palliative chemotherapy treatment and with two palliative esophageal stents. Other past medical history included active hepatitis B, arterial hypertension and dyslipidaemia. He was an ex smoker of 80 pack-year units.

[Efficacy of stent placement in treatment of malignant tracheoesophageal fistula and relevant factors of fistula closure].

Objective: To investigate the efficacy of stent placement in the treatment of malignant tracheoesophageal fistula (MTEF) and the factors affecting the closure of the fistula. Methods: Clinical, pathological, laboratory, and imaging data of 288 patients with MTEF admitted to Zhongda Hospital, Southeast University from 2015 to 2021were retrospectively analyzed. Among them, there were 208 males; the age was (63.6±10.5) years. A total of 94 patients received conservative treatment (conservative group), and 194 in the stent group (170 cases with esophageal stents and 24 cases with tracheal stents). Patients were followed-up at 2 weeks, 1 month, 3 months, and 6 months to evaluate the effect of stent implantation. Multivariable logistic regression was used to analyze factors affecting fistula closure. Results: Age, fistula size, leukocyte count before treatment, and fistula location were significantly different between the conservative group and the stent group (P<0.05). The Karnofsky functional status (KPS) score before treatment in the conservative group was lower than the stent group, (45.1±1.0) vs (51.8±0.7) scores, respectively (P<0.001). After 2 weeks and 1 month of treatment, improvement in KPS scores was significantly better in the stent group than in the conservative group (P<0.05). At 1 month, the pulmonary infection rate in the stent group was 33.5% (58/173), significantly lower than that in the conservative group [77.0% (47/61); P<0.001]. Among the 288 patients, the fistula was closed in 196 patients and unclosed in 92 patients. Fistula size (OR=3.429, 95%CI: 1.623-7.829, P=0.001), leukocyte count before treatment (OR=1.160, 95%CI: 1.027-1.317, P=0.018), KPS score before treatment (OR=0.898, 95%CI: 0.848-0.945, P<0.001) and the treatment method (conservative treatment as reference, esophageal stent OR=0.010, 95%CI: 0.004-0.030, P<0.001; tracheal stent OR=0.003, 95%CI: 0.000-0.042, P<0.001) were factors affecting fistula closure. In the 170 patients in the esophageal stent group, early complications (≤24 h) occurred in 71 patients, and late (>24 h) complications occurred in 11 patients. While in the 24 patients in the tracheal stent group, 9 had early complications and 2 had late complications. Conclusions: Stent placement is an effective treatment for MTEF compared to conservative treatment. Stent treatment, small fistula size, low pre-treatment leukocyte count, and high pre-treatment KPS score are beneficial to fistula closure.

[Related factors and prognosis analysis of esophagorespiratory fistula after esophageal cancer surgery].

Objective: To explore the factors associated with the development of esophagorespiratory fistula (ERF) after esophageal cancer surgery and its relationship with patient survival. Methods: A total of 241 patients with esophageal cancer after surgery, who received postoperative sputum suction through bronchoscope from West China Hospital of Sichuan University between January and December 2021 were included. The clinical data and airway features under bronchoscope of these patients were collected. Of the 241 patients, 203 were males (84.2%) and 38 were females (15.8%), aged (63.63±8.05) years. The related factors of ERF were analyzed by multivariate logistic regression analysis, and Kaplan-meier was used to analyze the relationship between bronchoscopic specific manifestations, treatment modality and patient survival. Results: Of the 241 postoperative patients with esophageal cancer, 21 (8.7%) developed ERF. There were 39 (16.2%) patients with bronchoscopic specific manifestations, including 16 cases (6.6%) of hyperemia, 13 cases (5.4%) of congestion, and 15 cases (6.2%) of erosion. Bronchoscopic specific manifestations of tracheal mucosa (OR=13.734, 95%CI: 3.535-29.074, P<0.001) and thoracotomy (OR=9.121, 95%CI 1.843-44.237, P=0.007) were independent risk factors for the development of ERF, and preoperative chemotherapy (OR=0.128, 95%CI: 0.052-0.607, P=0.006) was a protective factor in the occurrence of ERF. The median survival time was 224 (95%CI: 95-353)d in the stent-treated group (14 patients) after the onset of ERF, and the median survival time of patients in the supportive care group (7 patients) was 29 (95%CI: 8-50)d, and the survival difference was statistically significant (χ2=5.69, P=0.017). Conclusions: Bronchoscopic specific manifestations are independent risk factors for the development of ERF in postoperative patients with esophageal cancer and are useful in assessing the risk of developing ERF. After the occurrence of postoperative ERF, timely intervention by insertion of tracheal stents to seal the fistula may prolong the survival time of the patients.

A case of a death caused by an atrial-oesophageal-thoracic fistula after radiofrequency ablation of atrial fibrillation.

The report is about a 49-year-old man with rheumatic heart disease and atrial fibrillation. He underwent mitral valve replacement, tricuspid valvuloplasty, and atrial fibrillation radiofrequency ablation in the hospital. He vomited blood on the 2nd postoperative day, and the bleeding gradually worsened thereafter. He had to have repeated drainage of large amounts of blood from his right thoracic cavity and digestive tract. He died suddenly after undergoing an oesophageal endoscopy on the 24th postoperative day. The autopsy revealed an atrial-oesophageal-thoracic fistula. By excluding the possibility of the fistula being caused by complications from nasoenteric feeding, tracheal intubation, and a foreign body ingestion, we determined that the atrial-oesophageal-thoracic fistula was a complication after radiofrequency ablation according to the finding of coagulation necrosis of the myocardial cells at the left atrium fistula. In addition, we also performed an elemental analysis on the radiofrequency ablation area and other cardiac tissues by scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) and found five metal elements, Cr, Cu, Zn, Mn, and Ti, which specifically existed in the radiofrequency ablation area. This finding has the potential to serve as new evidence for radiofrequency ablation and is a worthy direction of research.

A rare cause of a bulging mass in the mid esophagus.

Aortoesophageal fistula, a rare and potentially fatal disease, is an abnormal connection between the aorta and esophagus. We have recently identified a case of aortoesophageal fistula, but it was characterized by submucosal bulge of esophagus, not gastrointestinal bleeding. And he was treated promptly.

Endoscopic diagnosis of primary aortoesophageal fistula: An extremely rare cause of acute upper gastrointestinal bleeding.

Primary aortoesophageal fistula, an abnormal communication between native aorta and oesophagus, is an extremely rare cause of upper gastrointestinal bleeding. The typical symptoms, known as the Chiari´s triad, are only present in 45% of cases. It has a high mortality, so early diagnosis is essential to increase the probability of survival. We present a case report of a patient with massive upper gastrointestinal bleeding due to primary aortoesophageal fistula.

Experience in the treatment of esophageal anastomosis dehiscence using self-expanding metallic prosthesis.

INTRODUCTION: esophageal anastomosis dehiscence is a serious complication after esophageal cancer surgery with high mortality risk. One of the treatment options is self-expanding esophageal prostheses. Our aim was to evaluate the outcome of esophageal prostheses in the management of suture dehiscences after oncologic surgery. MATERIAL AND METHODS: we performed a descriptive and retrospective study with patients diagnosed with esophageal anastomosis fistula or dehiscence treated by esophageal prosthesis between the years 2015 and 2021. We considered technical success as the correct positioning of the prosthesis with visualization of anastomotic leak closure after release of the prosthesis during endoscopy, and clinical success the resolution of dehiscence after removal of the prosthesis 8 weeks after positioning. RESULTS: technical success was 95% and clinical success 89%. CONCLUSION: in our center, esophageal prostheses are a treatment option for fistulas and anastomotic dehiscence after surgery with a high success rate and few complications.
