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.

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.

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.

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.

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.

[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.

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.

[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.

Spontaneous Aortoesophageal Fistula And Ruptured Aortic Aneurysm - A Case Report On Combined Aortic And Esophageal Prosrhesis Palliative Treatment.

Aortoesophageal fistulas are uncommon, dreadful vascular events, most frequently found in the setting of thoracic aorta aneurysms. Patients usually present with thoracic pain, dysphagia and sentinel hematemesis - the Chiari triad - followed by life threatening hematemesis. Emergent open surgery with debridement of necrotic tissue and in situ aortic graft repair is currently the best strategy. However, in patients which cannot withstand surgery, endovascular repair is currently gaining acceptance as a palliative treatment or as a bridge to surgery. We present a case of a 55-year-old female with a past of heavy alcohol abuse and a previously unknown massive aortic aneurysm, who presented to the emergency department complai- ning of acute dysphagia and epigastric pain. An abdominal ultrasound revealed left pleural effusion and suspected clots in the pleural space. A thoracic CTA was promptly done, where a spontaneous ruptured aortic aneurysm with aortoesophageal fistula was discovered. The team, fearing open surgery due to poor cardiac function, opted for a thoracic endovascular aortic repair. The aortoesophageal fistula dissected the esophageal wall in all of its thickness without rupture into the lumen. This was complicated with esophageal ischemia, aneurysmal sac infection and mediastinitis. Because the patient was in shock, in order to help control the infection, an esophageal prosthesis was placed, followed by proximal esophagostomy, distal esophageal closure and gastrostomy. Six months after initial presentation, the patient died at the emergency room, shortly after reentering with massive hematemesis and hypovolemic shock of undetermined origin.

Thoracic endovascular aortic repair for esophageal cancer invading the thoracic aorta: a questionnaire survey study.

BACKGROUND: Locally advanced esophageal cancer occasionally invades the aorta, and hemorrhage from the esophagoaortic fistula can cause sudden death. Thoracic endovascular aortic repair (TEVAR) enables hemostasis in such cases, and prophylactic TEVAR can prevent fatal hemorrhagic events during treatment. However, its efficacy in Japan has not been evaluated. This study aimed to clarify the clinical significance of TEVAR in esophageal cancer patients. METHODS: The Japan Esophageal Society conducted a questionnaire survey targeting authorized or semi-authorized member institutes of the Authorized Institutes for Board Certified Esophageal Surgeons. Patients who underwent TEVAR for esophageal cancer were identified from 19 institutes. Data on patient demographics, treatment performed, and survival rate were obtained using the questionnaire. The Kaplan-Meier method was used for survival analysis and to compare differences in survival rates between those who underwent TEVAR for hemorrhage and those for preoperative prophylaxis. RESULTS: Of the 41 patients identified, 20 patients underwent TEVAR for hemorrhage or impending hemorrhage from the esophagoaortic fistula, while 21 patients underwent TEVAR as preoperative prophylaxis. The median survival time after TEVAR was 135 days in the hemorrhage or impending hemorrhage group and 378 days in the preoperative prophylaxis group. Eighteen patients underwent esophagectomy after TEVAR. No hemorrhagic event was observed during the perioperative period. The median survival time of the patients who underwent esophagectomy was 373 days. Some patients who achieved R0 resection obtained long-term survival. CONCLUSION: TEVAR is an efficacious modality to control a life-threatening hemorrhage from esophagoaortic fistula and helps to prolong the survival of patients with locally advanced esophageal cancer invading the aorta.

Cerebral arterial air emboli after stent insertion in esophageal cancer complicated with esophago-left atrial fistula: An autopsy case and review of the literature.

Cerebral arterial air embolism is a rare and unexpected complication of advanced esophageal cancer. The entry of air to systemic circulation is an esophago-left atrial or pulmonary vein fistula formation. Herein, we report an autopsy case of a 64-year-old man. He was diagnosed esophageal cancer 2 years ago and underwent chemotherapy and concurrent chemoradiotherapy but the disease progressed, unfortunately. Then two metal stents were inserted into the middle thoracic esophagus as a palliation of dysphagia. After initiation of oral intake, he developed deterioration of consciousness. The cranial computed tomography showed cerebral arterial air emboli with multiple low-density areas. He failed to gain consciousness again and died one and half days later. In a literature survey, this autopsy case is the first presentation that confirmed histologically the close association between stent placement and formation of esophago-left atrial fistula. Due to the fatality of cerebral arterial air embolism, clinicians should keep in mind the possibility of this catastrophic complication after multimodality treatment of esophageal cancer.

Treatment considerations for cervical and cervicothoracic spondylodiscitis associated with esophageal fistula due to cancer history or accidental injury: a 9-patient case series.

BACKGROUND: The combination of cervical spondylodiscitis and esophageal fistula is rare but life-threatening. Due to both the rarity of these conditions' coincidence and the complexity and heterogeneity of individual cases, there is no optimal treatment or management approach. The aims of this study are to obtain an overview of patients' outcomes and to discuss treatment options. METHOD: This study is a retrospective analysis of patients who presented with cervical spondylodiscitis and associated esophageal fistula between January 2010 and November 2018. We examined reports of 59 patients who suffered from cervical spondylodiscitis and included nine patients (15.25%) who had an esophageal fistula as the underlying cause. We assessed clinical findings, treatment, and outcome. RESULTS: Three of the nine patients were female, and the mean age of the sample was 64.56 years. Six of the patients had a history of esophagopharyngeal cancer and had undergone tumor resection followed by radiotherapy. Two of the remaining patients' fistulas were caused by an iatrogenic injury during cervical spine surgery and a swallowed toothpick; in the final case, the origin remained unclear. Five patients presented with tetraparesis or tetraplegia, and the other four patients were neurologically intact. In seven cases, dorsal instrumentation was initially performed. Three patients secondarily received a ventral approach for debridement, and one received explantation of the ventral implants. Two patients died during the hospital stay, and three were transferred to a palliative care unit. Thus, the spondylodiscitis and esophageal fistula were cured in only four patients. At discharge, two patients were neurologically intact, two others remained in tetraparesis. CONCLUSIONS: Cervical spondylodiscitis in association with an esophageal fistula carries high morbidity and high mortality. Because patients whose infections are not cured have high morbidity, we recommend using interdisciplinary and individual management, including definite surgical treatment of the discitis and fistula, in every case.

Primary aortoesophageal fistula: A fatal outcome.

Aortoesophageal fistula is a rare but life-threatening cause of massive gastrointestinal bleeding. We reported a case of primary aortoesophageal fistula associated with thoracic aortic pseudoaneurysm. Esophagogastroduodenoscopy demonstrated a bulging erosive lesion coated with fibrin. The patient was therefore diagnosed as malignant esophageal mesenchymoma initially. An emergency contrast-enhanced computed tomography revealed an out-pouching saccular aneurysm protruding toward the esophagus at the level of T8-9. The patient expired rapidly due to intractable massive bleeding. Assumptive diagnosis of esophageal malignancy leads to a loss of the most optimal time-point for operation thus negatively affecting the patient survival.

Pneumopericardium as a rare complication after esophagopericardial fistula.

Pneumopericardium is a rare clinical entity which is often complicated by trauma. Pneumoperdicardium resulting after esophagopericardial fistula is much rarer. We present a case of pneumopericardium as the complication of esophagopericardial fistula in a 53-year-old man. After undergoing radiotherapy for 26 times, the patient got a fever and an unspecified thoracic pain. Echocardiography showed the rectilinear echoes in the pericardium. Chest computed tomography revealed pneumopericardium, pericardial effusion, recurrence of lung cancer, and pneumonia in right lower and left lung.

Delayed traumatic rupture of the thoracic aorta into the esophagus.

A case of delayed rupture of the thoracic aorta into the esophagus after blunt thoracic injury is reported. It involved a hemodynamically stable 18-year-old male patient without any clinical or radiological signs to indicate aortic injury. Aortoesophageal fistula presented in the fifth post traumatic day, with a sudden dyspnea episode, intraperitoneal hemorrhage and lower gastrointestinal bleeding, due to intraperitoneal and intragastric rupture of intramural esophageal hematoma.

Oesophageal pleural fistula presenting with Parvimonas micra infection causing cervical and brain abscesses.

Parvimonas micra (P. micra) infections causing spinal cord compression are extremely rare. We report an occult oesophageal pleural fistula presenting with spinal epidural and brain abscesses resulting in severe neurological deficits caused by P. micra. Molecular detection proved to be instrumental in identifying the causative pathogen. Essential management with decompression, drainage, antibiotics and fistula repair lead to a good outcome.
