A 60-year-old man presented with severe abdominal pain, two episodes of massive haematemesis and chest discomfort. CT angiography showed a saccular aneurysm of the juxtaphrenic aorta with possible oesophageal erosion. Upper GI endoscopy revealed external compression of the lower oesophagus—near total luminal obstruction with impending rupture of the aortic aneurysm. Emergency aneurysmal repair by interposition grafting using 20 mm Dacron graft with oesophageal–gastric reconstruction done. Postoperative period was uneventful

The ideal management of bronchoesophageal fistulas is a debated topic. While open surgical repair remains the most definitive treatment, not all patients are fit for surgery. In this communication, we present a patient who developed a bronchoesophageal fistula 1 year after an Ivor Lewis esophagectomy that involved the native oesophagus and right mainstem bronchus. Endoluminal vacuum therapy was successful at closing this benign bronchoesophageal fistula.

Management of an uncorrected broncho-oesophageal fistula in the perioperative period is a challenge for the anaesthesiologist. Positive pressure ventilation which is inevitable during surgery will lead to gastric insufflation and there is a high risk of aspiration of gastric contents. In this case report, we discuss how we used a double lumen tube to occlude a pericarinal broncho-oesophageal fistula. This method was quite effective as it obviated the need for isolating the lung as well as ensured smooth delivery of positive pressure ventilation during the surgery.

A 79-year-old hypertensive man with chronic type B aortic dissection (TBAD) came with acute chest pain. CT revealed partially thrombosed aneurysmal dilatation of false lumen, compressing trachea and oesophagus (chronic complicated TBAD) with the extremely tortuous descending thoracic aorta ([figures

Objectives The presence of a fistula between the thoracic aorta and the esophagus is a rare and highly fatal condition. This study aimed to evaluate the outcomes of the surgical treatment of an aortoesophageal fistula (AEF). Methods We retrospectively reviewed patients with AEF who underwent surgery at our institution. Results Between 2007 and 2018, a total of 10 patients who underwent surgery for AEF. The mean age was 63 ± 12 years, and 6 patients were men. Four patients had primary AEFs and 6 patients had secondary AEFs (3 graft replacements and 3 thoracic endovascular aortic repairs). The timing of AEF since graft replacement or thoracic endovascular aortic repairs was 21.6 ± 27 days. We performed aortic replacement with a prosthetic graft (4 patients) or a homograft (5 patients) and extra-anatomical bypass due to a previous aortic graft infection (1 patient). As a treatment of the esophagus, we conducted primary repair in 7 of 10 patients. The median lengths of hospital and intensive care unit stay were 59 days (range, 9-225 days) and 6.3 days (range, 1-87 days), respectively. Seven patients achieved oral feeding after a median 10.3 postoperative days (range, 7-78 postoperative days). Two of the 10 patients died of sepsis at 9 and 74 days postoperatively. Conclusions The strategy for patients with AEF should be individualized. Our surgical strategy for AEF, which includes simultaneous aortic graft replacement and primary repair of esophagus in the same operative field, is feasible and promising.

To determine risk factors, treatment outcomes, and prognostic factors for esophageal fistula (EF) in patients with esophageal squamous cell carcinoma (ESCC) during radiotherapy.Between 2010 and 2018, 109 patients with EF during radiotherapy were retrospectively collected. A controlled cohort including 416 patients who received definitive chemoradiotherapy without EF was used to compare risk factors and survival outcomes. Univariate and multivariate logistic regression analyses were performed to identify predictors of EF. Propensity score matching (PSM) was applied to adjust for potential confounding factors.Multivariate analysis demonstrated that sex, body mass index, alcohol history, esophageal ulceration, primary tumor length, T stage, and absolute lymphocyte count were independent risk factors for EF. After PSM, patients with EF showed remarkably worse prognosis than those without EF (median overall survival: 13.0 versus 20.5 months; P = 0.009). For patients with EF, serum albumin level (≥ 35 g/L), subsequent radiotherapy, and fistula closure were associated with significantly prolonged survival. In addition, esophageal-mediastinum fistula and subsequent radiotherapy were positive predictors for fistula closure.We identified risk factors for radiotherapy-related EF and its unfavorable prognosis in patients with ESCC. Of them, patients with serum albumin level of ≥ 35 g/L, subsequent radiotherapy after EF, and fistula closure had a more favorable survival.

Left atrial-esophageal fistula (AEF) following radiofrequency ablation for atrial fibrillation is a rare and potentially lethal complication. Although surgical management is associated with improved outcomes, the optimal approach remains to be elucidated. We describe a case of AEF which was treated with a simultaneous repair of the atrium and esophagus via a right thoracotomy with an extra-pericardial off-pump approach.

BACKGROUND Massive upper gastrointestinal (GI) bleeding is usually urgent and severe, and is mostly caused by GI diseases. Aortoesophageal fistula (AEF) after thoracic aortic stent grafting is a rare cause of this condition, and has a poor prognosis with a high mortality rate. The clinical symptoms of AEF are usually nonspecific, and the diagnosis is often difficult, especially when upper GI bleeding is absent. Early identification, early diagnosis, and early treatment are very important for improving prognosis. CASE SUMMARY A 74-year-old man was admitted to the infectious disease department with > 10-d fever and 10-mo prior history of thoracic aortic stent grafting for thoracic aortic penetrating ulcers. Blood tests revealed elevated inflammatory indicators and anemia. Chest computed tomography (CT) showed postoperative changes of the aorta after endovascular stent graft implantation, pulmonary infection and pleural effusion. Pleural effusion tests showed empyema. After 1 wk of anti-infective treatment, temperature returned to normal and chest CT indicated improvement in pulmonary infection and reduction of pleural effusion. Esophageal endoscopy was performed because of epigastric discomfort, and showed a large ulcer with blood clot in the middle esophagus. However, on day 11, hematemesis and melena developed suddenly. Bleeding stopped temporarily after hemostatic treatment and bedside endoscopic hemostasis. Thoracic and abdominal aortic CT angiography confirmed AEF. Later that day, he suffered massive hemorrhage and hemorrhagic shock. Eventually, his family elected to discontinue treatment. CONCLUSION AEF should be strongly considered in patients with a history of aortic intervention who present with fever, especially with empyema.

Background: Although trachea-esophageal fistula (TEF) and esophageal atresia (EA) is rare, it is one of the most common congenital anomaly. There is paucity of data due to rarity of condition. More and more data on clinical profile, complications, and outcome are needed to guide the future research. Objective: To study clinical profile of newborns with TEF and EA and factors associated with outcome. Materials and Methods: Hospital based prospective study was carried out among 21 newborns with TEF and EA. Diagnosis was confirmed by investigations like X-ray chest after passing nasogastric catheter. Depending upon final diagnosis type of surgery required was determined and procedure was carried out as per the standard guidelines and operating techniques. All cases were followed till the complete post-operative period and the complications and outcome was assessed. Outcome was classified as death or discharge. Results: Males outnumbered females giving a male to female ratio of 2.5:1. 57.1% did not require ventilator pre-operatively. 61.9% of the cases had no associated abnormality. The most common type of surgery required and performed was tracheoesophageal repair in 52.4% of the cases. Two cases (9.5%) died during the post-operative period. 14 cases (66.7%) recovered and were discharged. Most common complication was anastomotic leak (57.1%). Term status and associated abnormalities were not found to be associated with outcome like death (p>0.05). Conclusion: Trachea-esophageal fistula and esophageal atresia was more common in males. Tracheoesophageal repair was commonly required surgery. Recovery rate was good. Anastomotic leak was most common complication. Outcome like death was not associated with term status and associated abnormalities. Keywords: Clinical profile, Newborns, Tracheoesophageal fistula, Atresia, Outcome

Aim: To determine the different factors leading to poor outcome in operated case of esophageal atresia and trachea-esophageal fistula (EA-TEF). Material and Methods: This is a retrospective non-randomized comparative study. All the patient who presented with EA-TEF to us were included in the study. The patients who were not operated and patient who were discharged against the advice were excluded from the study. Patients were divided in to two groups. Group-A- Those who have survived after the surgery-39 and Group-B those who expired after the surgery-38. Various parameters were considered in relation to pre-operative, intra-operative and post-operative factors. To name few antenatal findings, maternal hemoglobin, gestational age, gap between both the end, duration of procedure, need for mechanical ventilation, early start of NG feed, need for blood products and postoperative complications. Results: Preoperative factor which had significant negative impact on survival were antenatally diagnosed polyhydramnios, maternal anemia, gestational age and associated severe cardiac anomalies. Mean operating time was more in group-B. Whenever surgeons or anaesthesiologists decided to continue postoperative ventilation the outcome was poor- 34 needed post-operative ventilation in group-B versus 12 in group A. Need for blood transfusion and need for platelets transfusion did not show significant difference among two groups but the need for plasma transfusion had poor survival. SIRS/sepsis played important determining factor in survival of EA-TEF. Patients who could be fed early, had better survival. Pneumothorax, pneumonia and leak didn’t show significant difference in survival. Conclusion: Different factors before, during and after the surgery have impact on outcome of EA-TEF. We should be able to formulate prognostic score which is based our local needs and available resources.

A 61-year-old man with hypertension and psoriasis, which was treated with adalimumab, was admitted after a 1-month history of fever following a dental implantation. Computed tomography of the chest revealed a pseudoaneurysm in the aortic arch, and blood culture grew Salmonella enterica. A diagnosis of mycotic pseudoaneurysm of the aortic arch due to Salmonella was made, and he was treated with cefoperazone–sulbactam. During his hospital stay, he developed hoarseness followed by haemoptysis, and underwent thoracic endovascular aortic repair followed by emergency open surgical repair. However, he died 5 weeks after the surgery due to acute upper gastrointestinal bleeding, which was confirmed as an aortoesophageal fistula by oesophagogastroscopy.

Background Esophageal fistula is one of the most serious complications of chemotherapy or chemoradiotherapy (CRT) for advanced esophageal cancer. This study aimed to evaluate the performance of quantitative computed tomography (CT) analysis and to establish a practical imaging model for predicting esophageal fistula in esophageal cancer patients treated with chemotherapy or chemoradiotherapy. Methods This study retrospectively enrolled 204 esophageal cancer patients (54 patients with fistula, 150 patients without fistula) and all patients were allocated to the primary and validation cohorts according to the time of inclusion in a 1:1 ratio. Ulcer depth, tumor thickness and length, and minimum and maximum enhanced CT values of esophageal cancer were measured in pretreatment CT imaging. Logistic regression analysis was used to evaluate the associations of CT quantitative measurements with esophageal fistula. Receiver operating characteristic curve (ROC) analysis was also used. Results Logistic regression analysis showed that independent predictors of esophageal fistula included tumor thickness [odds ratio (OR) = 1.167; p = 0.037], the ratio of ulcer depth to adjacent tumor thickness (OR = 164.947; p p = 0.039) in the primary cohort at baseline CT imaging. These predictors were used to establish a predictive model for predicting esophageal fistula, with areas under the receiver operating characteristic curves (AUCs) of 0.946 and 0.841 in the primary and validation cohorts, respectively. The quantitative analysis combined with T stage for predicting esophageal fistula had AUCs of 0.953 and 0.917 in primary and validation cohorts, respectively. Conclusion Quantitative pretreatment CT analysis has excellent performance for predicting fistula formation in esophageal cancer patients who treated by chemotherapy or chemoradiotherapy.

Oesophageal rupture after pneumonectomy is very rare. Management remains a significant challenge. This current case report describes a patient that underwent right pneumonectomy for right central squamous cell carcinoma. On the third day after the operation, food residues were observed in the thoracic tube. Considering oesophageal rupture, surgery was performed. Intraoperative oesophageal rupture was observed and intermittent suture was performed. Unfortunately, an oesophageal pleural fistula developed. Anti-infection treatment, chest drainage, thoracic irrigation, nutrition support and stent implantation were used after the operation. The patient recovered smoothly and had no discomfort when eating. Oesophageal rupture after pneumonectomy is extremely rare and treatment is very difficult. In our opinion, surgical repair is the key to the treatment of oesophageal rupture. Once an oesophageal pleural fistula occurs, enhanced nutrition, adequate irrigation and drainage and stent implantation are critical factors.

Introduction: Atrial-esophageal fistula (AEF) is a rare but life-threatening complication of catheter ablation. The clinical presentation and mortality risk factors of AEF have not been fully elucidated. The aim of this study was to systematically review the clinical characteristics and prognosis of AEF. Methods: PubMed was searched from inception to October 2020 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement protocol. Results: A total of 190 AEF patients were included. The mean age was 59.29 ± 11.67 years, 74.21% occurred in males, and 81.58% underwent radiofrequency ablation. AEF occurred within 30 days after ablation in 80.82% of patients and occurred later in patients presenting with neurological symptoms compared with other symptoms (median of onset time: 27.5 days vs. 16 days, p < 0.001). Clinical presentation included fever (81.58%) and neurological symptoms (80.53%). Chest computed tomography (abnormal rate of 91.24%) was the preferred diagnostic test, followed by magnetic resonance imaging of the brain (abnormal rate of 90.91%). Repeated testing improved diagnostic evaluation sensitivity. Distinctive imaging results included free air in the mediastinum (incidence rate of 81.73%) and air embolism of the brain (incidence rate of 57.53%). The overall mortality was 63.16%, with worse nonsurgical treatment outcomes compared with outcomes of surgical treatment (94.19% vs. 33.71%, p < 0.001). Conservative or stent intervention was an independent risk factor for mortality. Age (adjusted odds ratio, 1.063, p = 0.004), presentation with neurological symptoms (adjusted odds ratio, 5.706, p = 0.017), and presentation with gastrointestinal bleeds (adjusted odds ratio, 3.009, p = 0.045) were also predictors of mortality. Conclusions: AEF is a fatal ablation complication. AEF can be diagnosed using a combination of a clinical history of ablation, infection, or neurological symptoms and an abnormal chest CT. Our analysis supports that surgical treatment reduces the mortality rate.

Objetivos: mostrar la eficacia y seguridad de los stents metálicos autoexpandibles para el manejo endoscópico de las fístulas esofágicas. Materiales y métodos: se evalúo una serie de casos de manera retrospectiva entre el 2007 y el 2017, en los que se manejaron a 11 pacientes con un stent metálico autoexpandible para el manejo de fístula esofágica, en quienes se realizó el diagnóstico por clínica, endoscopia digestiva alta o estudios radiológicos en la unidad de gastroenterología del Hospital Universitario San Ignacio (HUSI) de Bogotá D. C., Colombia. Resultados: el principal síntoma inicial fue la disnea en 27,3 % de los casos, seguido por tos en un 18,2 %. El hallazgo más frecuentemente encontrado durante el seguimiento fue el derrame pleural en el 36,4 %, se realizó el diagnóstico de fístula en el 45,5 % con esofagograma y el tipo de lesión más reportada fue la fuga en la anastomosis esofagoentérica, con un 45,5 %, seguida de la esofagopleural, con un 36,4 %; y estos pacientes fueron manejados con un stent metálico autoexpandible. En el 100 % hubo éxito técnico y la resolución del defecto se evidenció en el 72,7 % de los casos. La única complicación reportada fue el desplazamiento del stent en el 27,3 %, y en un paciente se requirió el cambio del stent en 3 oportunidades. El promedio de estancia hospitalaria fue de 41,5 días. Conclusiones: el manejo endoscópico de las fístulas esofagogástricas con stents metálicos autoexpandibles es efectivo y seguro, con una baja tasa de complicaciones.

Adult, benign, non-iatrogenic bronchoesophageal fistula (BEF) is a rare condition, which is occasionally described in single case reports. Therefore, little is known about its possible causes, presentation and management. A systematic search of the literature in MEDLINE, PubMed Central and EMBASE databases between 1990 and 2020 was carried out to identify all cases of BEF. The initial database search identified 19,452 articles, of which 183 (251 individual patient cases) were included in the final analysis. Main causes of BEF were congenital malformations (97/251, 38.7%) and infections (82/251, 32.7%), while 33/251 (13.1%) fistulae were regarded as idiopathic and 39/251 (15.5%) attributed to other causes. Esophagograpy was the most sensitive method of diagnosis (97.4%) compared with esophagoscopy (78.9%), computed tomography (49.6%) and bronchoscopy (46.0%). Definitive treatment was surgical for 176 patients (70%), endoscopic for 25 (10%) and medical for 37 (14.7%). Compared with congenital BEFs, infective BEFs had shorter median symptom duration and were distributed more proximally over the bronchial tree. Definitive treatment was almost only surgical for congenital BEFs, while infective BEFs were treated also endoscopically (12%) and by medical therapy (38%). Morbidity, treatment failure and recurrence rates were higher for infective BEFs. BEFs are rare. Symptoms are non-specific and a high index of suspicion is necessary for diagnosis. Patients with infective BEF tend to have a more severe clinical picture than those with congenital BEF. Surgery is the main treatment for patients affected by congenital BEF, while infective BEFs may heal conservatively.

Background Esophageal fistulae are rare, though serious, complications of anterior cervical surgery. Hardware-related issues are important etiologic factors. Patient-specific implants (PSIs) have increasingly been adapted to spinal surgery and offer a range of benefits. Zero-profile implants are a recent development primarily aimed at combating postoperative dysphagia. We report the first use of a 3-dimensional (3D)-printed zero-profile PSI in managing implant failure with migration and a secondary esophageal fistula. Methods A 68-year-old female had a prior C5-7 corpectomy with cage and plate fixation, as well as posterior C3-T1 lateral mass fixation, complicated by anterior plate displacement, resulting in pseudoarthrosis and an esophageal fistula. A 3D-printed zero-profile PSI was designed and implanted as part of a revision procedure to assist in recovery, prevent recurrence, and facilitate bony fusion. Results Optimal implant placement was achieved on the basis of preoperative virtual surgical planning. By 1 month postoperatively the patient had significantly improved, with evidence of esophageal fistula resolution and radiographic evidence of optimal implant placement. Conclusions Zero-profile 3D-printed PSIs may combat common and serious complications of anterior cervical surgery including postoperative dysphagia and esophageal fistulae. Further research is required to validate their widespread use for either cervical corpectomy or diskectomy and interbody fusion.

Background Gastric pull-up (GPU) procedures may be complicated by leaks, fistulas, or stenoses. These complications are usually managed by endoscopy, but in extreme cases multidisciplinary management including reoperation may be necessary. Here, we report a combined endoscopic and surgical approach to manage a failed secondary GPU procedure. Case summary A 70-year-old male with treatment-refractory cervical esophagocutaneous fistula with stenotic remnant esophagus after secondary GPU was transferred to our tertiary hospital. Local and systemic infection originating from the infected fistula was resolved by endoscopy. Hence, elective esophageal reconstruction with free-jejunal interposition was performed with no subsequent adverse events. Conclusion A multidisciplinary approach involving interventional endoscopists and surgeons successfully managed severe complications arising from a cervical esophagocutaneous fistula after GPU. Endoscopic treatment may have lowered the perioperative risk to promote primary wound healing after free-jejunal graft interposition.

Background This study aims to review and compare the clinical presentation, management, and outcome in patients with tumor-related (TR) and nontumor-related (NTR) aorto-esophageal fistula (AEF) and aorto-bronchial fistula (ABF) with particular focus on the thoracic endovascular aortic repair. Methods We retrospectively reviewed a series of 16 consecutive patients with TR (n = 8) and NTR (n = 8), ABF (n = 6), and AEF (n = 10) admitted to our hospital from 2011 to 2019. Results The median age was 62 years (range 46–81), with 11 men. The most common predisposing factor was esophageal or gastric cardia cancer (n = 6), followed by open repair of the thoracic aorta (n = 5). Endoluminal vacuum therapy (Endo-SPONGE®) accounted for 3 cases of AEFs. Thoracic endovascular aortic repair (TEVAR) was applied in 13 patients (4 with ABFs and 9 with AEFs). The primary technical success of the TEVARs was 100%. One patient (8%) was complicated with postoperative middle cerebral artery syndrome and left-sided hemiparesis. The respective in-hospital, 6-month, and 1-year mortality rates were 0% (n = 0), 25% (n = 2), and 25% (n = 2) for the NTR group and 63% (n = 5), 88% (n = 7), and 100% (n = 8) for the TR group. After a mean period of 13 months, 5 (31%) patients were still alive, and one patient lost to follow-up after 11 months. The survivors (n = 5) had all nontumor-related ABF. Progression of underlying cancer and hemodynamic shock were the most common causes of death. Conclusions TEVAR represents a reliable option in the treatment of NTR ABFs. In the cases of TR fistulas and NTR AEFs, TEVAR should be applied more selectively. The associated mortality remains very high.

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.

Aim: The purpose of the study was to define and then to compare particularly the morphological profiles of the main morphological types of esophageal carcinoma (EC). Patients, Materials and Methods: The studied group included 46 operated EC patients. Few parameters were clinical (gender and age). The rest of them described both gross and histological features of the entire group and of the two main histological types of carcinoma (lesion’ site, lateral extension, lesion dimensions, gross aspect, and histological type, and tumor grade, and stage). Stratification scales of cases were defined according to each parameter in order to compare the data and a statistical apparatus [Student’s t-test and χ2 (chi-squared) test] was used. Results: The studied tumors were encountered mostly in mature adult and elderly men, usually in the lower segments of the esophagus. Many of them had between five and ten cm in the long diameter and produced stenosis. Most of them had infiltrating appearance combined often with protruding or/and ulcerated aspects. Usually, the tumors were poorly differentiated and in stage III. The two main histological types of EC showed different morphological profiles. Data from the literature revealed sometimes wide ranges of variation for the studied morphological parameters. Our results were within these ranges of variation. Conclusions: ECs proved to be aggressive and late diagnosed tumors in general, with distinct morphological and behavioral profiles for the two main histological types. Comparisons with literature data confirmed many of our observations regarding the clinical and morphological aspects of both ECs as a whole and its histological types.

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.

Thoracoscopic Repair of Esophageal Atresia with Tracheoesophageal Fistula (TREAT) is now an established procedure. The anastomosis performed thoracoscopically is always compared to the hand sewn anastomosis in open surgery. The present study analyses the outcome of TREAT versus open repair in terms of radiological index representing the esophageal calibre. Patients with esophageal atresia-tracheoesophageal fistula (EA-TEF) operated by open repair and TREAT were evaluated. An esophageal calibre anastomotic index (EACI) was formulated based on measurements performed on contrast esophagogram at 3 months or later. The diameter of the esophagus at the level of anastomosis was measured, along with ratios of radiologically measured values both above and below the anastomosis; based on which an index was calculated. A value closer to 1 was considered normal, whereas a ratio

We present a case of a port malposition into the azygos vein resulting in both a broncho-esophageal and veno-bronchial fistula. While complications of central venous catheter malposition into the azygos vein are well documented in literature, these unique complications have not yet been described. This case underscores how utilizing state of the art technology like intra-cavity electrocardiography rather that reliance on fluoroscopy can help eliminate catheter malposition and its potential catastrophic consequences.

Endoscopic esophageal stent implantation is an effective method for dysphagia management in malignant esophageal stricture. However, this technology is associated with the risk of many complications, including those fatal to life. These include bleeding, restenosis, stent fragmentation and destruction, stent migration, pneumomediastinum, the formation of esophageal fistulas, perforations, clogging of the stent with food, retrosternal pain, gastroesophageal reflux changes, airway compression, aspiration pneumonia, and fever. The overall complication rate is 3640%. Mortality rates associated with stenting is between 3.9 and 27.2%. Nevertheless, today there are ways to minimize the incidence of complications due to the constant progress of endoscopic technologies and improvements in the design of modern stents. In addition, most endoscopic interventions can manage the vast majority of complications effectively after stent implantation subject to their early detection. Optimal selection of an esophageal stent and careful selection of patients with a low risk of complications associated with stent implantation are important problems in the prevention of complications to achieve high efficiency of stenting. Evaluation of risk factors for possible complications, the design of stents and their characteristics, as well as using modern methods of effective management of possible complications improves the quality and duration of life in incurable patients with esophageal cancer. The review reflects all possible complications of stenting in esophageal and gastroesophageal junction, factors affecting the occurrence of complications, as well as modern and effective methods of their correction and prevention.

Purpose This phase I trial aimed to determine the maximal tolerated dose (MTD) of incorporating a twice-weekly docetaxel and nedaplatin regimen into definitive concurrent chemoradiotherapy (CCRT) as radiosensitizers in patients with inoperable esophageal squamous cell carcinoma (ESCC). Methods The CCRT regimen included docetaxel (5 mg/m2, 10 mg/m2, or 15 mg/m2) and nedaplatin (5 mg/m2, 10 mg/m2, or 15 mg/m2) twice-weekly based on the traditional 3 + 3 dose escalation strategy, and radiotherapy (64 Gy in 32 fractions). The primary goals were to determine the MTD of concurrent chemotherapy and the dose limiting toxicities (DLTs). In-field objective response rate (ORR) was investigated. Results Fifteen patients had been recruited and analyzed. DLT involving persistent grade 3 esophagitis over 1 week was observed in all three patients (3/3) at dose level 3 (15 mg/m2), and two patients (2/6) experienced DLTs in the dose level 2 (10 mg/m2) due to esophageal fistula and persistent grade 3 esophagitis over 1 week, while one patient (1/6) treated at dose level 1 (5 mg/m2) exhibited DLT owing to Grade 3 increased liver enzymes, suggesting a MTD of 5 mg/m2. The in-filed ORR was both 100% in all patients and those receiving MTD. The 1-year loco-regional recurrence-free survival rate was 83.3%, 83.3% and 66.7% in dose level 1, 2, and 3, respectively. Conclusions The MTD of twice-weekly docetaxel and nedaplatin regimen was 5 mg/m2 in inoperable ESCC patients treated with definitive CCRT. Low dose concurrent docetaxel and nedaplatin showed promising radiosensitizing effect on in-filed disease control and good tolerability.

Background: The most common aortic arch abnormality is an aberrant right subclavian artery (ARSA). ARSA-esophageal fistula is a rare sequela that can present with a life-threatening upper gastrointestinal (GI) bleed. Case Report: We report the case of an 88-year-old male who presented with signs of upper GI bleeding. Esophagogastroduodenoscopy demonstrated extrinsic compression of the upper third of the esophagus with ulceration. Imaging studies revealed ARSA posterior to the esophagus with pseudoaneurysm formation. These findings confirmed an upper GI bleed secondary to ARSA-esophageal fistula. The patient underwent prompt embolization of the ARSA pseudoaneurysm, followed a few days later by coil embolization of the ARSA pseudoaneurysm. Despite these interventions, the patient continued to have bleeding with anemia. He and his family opted to avoid any further interventions and instead pursued comfort care. The patient was discharged to hospice and died 3 months later. Conclusion: ARSA-esophageal fistula is a rare but potentially lethal cause of upper GI bleeding. Initial signs and symptoms can be subtle, but the presence of a GI bleed requires immediate stabilization. Surgical interventions have been shown to have longer-lasting success, but endovascular repair may be an option for patients who are deemed unfit for surgery but still require prompt stabilization. Regardless of the intervention, mortality rates for ARSA-esophageal fistula are high.

Aims Rate, incidence, risk factors, and optimal management of atrio-oesophageal fistula (AOF) after catheter ablation for atrial fibrillation (AF) remain obscure. Methods and results All French centres performing AF ablation were identified and surveys were sent concerning the number of procedures, eventual cases of AOF, and characteristics of such cases. Eighty-two of the 103 centres (80%) performing AF ablation in France were included, with a total of 129 286 AF ablations since 2006 (93% of the whole procedures in France). Thirty-three AOF were reported (reported rate 0.026% per procedure) with a stable reported annual incidence despite the increasing number of procedures. Sensitivity of computed tomography (CT) scan for AOF was 81%. Mortality was 60%, significantly lower in case of surgical corrective therapy (31 vs. 93%, P = 0.001). Conclusion The reported rate of AOF after AF ablation in this nationwide survey was 0.026%, with a stable reported annual incidence over time. A normal CT scan does not rule out the diagnosis and should be repeated in case of suspicion. Prognosis remains poor with a mortality of 60% and crucially dependant of immediate surgical correction. No clear protective strategy has been proven effective.

Deviation of the esophagus during atrial fibrillation (AF) ablation can reduce esophageal injury. This study reports upon a novel esophageal retractor that utilizes vacuum suction and mechanical deflection to deviate the esophagus. The device was used in seven patients undergoing cryoballoon AF ablation. The esophagus was deviated 31.9 ± 4.4 mm to the right and 28.2 ± 5.9 mm to the left. Endoscopy at 4.4 ± 1.5 days postablation showed no esophageal injury. This study demonstrates the safe and effective deviation of the esophagus without a trailing edge with an esophageal retractor utilizing vacuum suction and mechanical deflection.

Background An atrio-esophageal fistula is an exceedingly rare but devastating complication of atrial fibrillation (AF) ablation procedures. Delays to diagnosis and definitive treatment herald a poor prognosis, with the development of catastrophic neurological injury or death secondary to cerebral air emboli. A high level of suspicion is essential to improve recognition of this rare but devastating condition. Case Report A 59-year-old man presented to the emergency department with an acute stroke and reduced consciousness. This presentation was preceded by an uncomplicated AF ablation 19 days prior and a subsequent emergency department attendance within a few days of his procedure, where he had presented with a history of new chest pain and reflux symptoms. Imaging revealed intra-cranial and intra-cardiac air, which was attributed to an uncontrolled atrio-esophageal fistula. Treatment options were limited by the patient's clinical instability and the patient was eventually palliated after developing catastrophic brain injury due to extensive cerebral air emboli. Why Should an Emergency Physician Be Aware of This? Patients typically first present to the emergency department with new symptoms of either gastroesophageal reflux or chest pain, therefore, early recognition by emergency physicians is vital. Characteristic symptoms alongside a recent history of a cardiac ablation procedure should prompt additional diagnostic imaging to look for evidence of an atrio-esophageal fistula.

Arterio-esophageal fistula (AEF) is a rare life-threatening cause of upper gastrointestinal bleeding. Realizing the risk factors and clinical presentations of AEF will enable us to provide timely diagnosis, efficient treatment, and better outcome. We present a 43-year-old Taiwanese man who had histories of destructive lung, innominate artery-trachea fistula, and received bilobectomy. He was admitted to our hospital with fresh blood drainage from nasogastric tube. He was diagnosed as right fifth intercostal artery esophageal fistula by computed tomography angiography and transcatheter arterial embolization was performed. The bleeding stopped and the patient was discharged uneventfully. The risk factors of AEF include esophageal foreign body, vascular surgery, thoracic arterial malformations, and concurrent chemoradiotherapy in T4-esophageal cancer. Computed tomography angiography may be the most sensitive diagnostic test. Transcatheter arterial embolization or endovascular stent grafting may be considered as the first-line treatment of AEF in the future.

Left subclavian artery esophageal fistula usually occurs after esophageal cancer surgery, which is a rare complication, and it is even rarer after stent implantation of left subclavian artery pseudo-aneurysm. This paper reports the case of a 21-year-old male patient with left subclavian artery pseudo-aneurysm. Two-plus months after stent implantation, he stopped anticoagulant and antiplatelet drugs and developed pain in his left upper limb. The patient was diagnosed with arterial fistula. He was discharged from the hospital successfully after several operations, such as thoracic aortic stent implantation, left common carotid artery left axillary artery artificial vascular bypass. Conclusion: Early diagnosis and positive treatment lead to a good prognosis for patients with esophageal left subclavian artery fistula.

Purpose The purpose of the present study was to investigate risk factors for esophageal fistula (EF) in patients with recurrent esophageal cancer receiving re-radiotherapy with or without chemotherapy. Methods We reviewed retrospectively the clinical characters and dosimetric parameters of 96 patients with recurrent esophageal cancer treated with re-radiotherapy in Cancer Hospital Affiliated to Shandong First Medical University between August 2014 and January 2021.Univariate and multivariate logistic regression analyses were provided to determine the risk factors of EF induced by re-radiotherapy. Results The median time interval between two radiotherapy was 23.35 months (range, 4.30 to 238.10 months). EF occurred in 19 patients (19.79%). In univariate analysis, age, T stage, the biologically equivalent dose in the re-radiotherapy, total biologically equivalent dose, hyperfractionated radiotherapy, ulcerative esophageal cancer, the length of tumor and the maximum thickness of tumor had a correlation with the prevalence of EF. In addition, age (HR = 0.170, 95%CI 0.030–0.951, p = 0.044), T stage (HR = 8.369, 95%CI 1.729–40.522, p = 0.008), ulcerative esophageal cancer (HR = 5.810, 95%CI 1.316–25.650, p = 0.020) and the maximum thickness of tumor (HR = 1.314, 95%CI 1.098–1.572, p = 0.003) were risk factors of EF in multivariate logistic regression analysis. Conclusions The incidence of EF was significantly increased in patients with recurrent esophageal cancer who underwent re-radiotherapy. This study revealed that age, T stage, ulcerative esophageal cancer and the maximum thickness of the tumor were risk factors associated with EF. In clinical work, patients with risk factors for EF ought to be highly concerned and individualized treatment plans should be taken to reduce the occurrence of EF.

We present the case of a 79 y.o. male diagnosed with tuberculosis and mediastinal lymphadenopathy fistulizing in the esophageal lumen. Despite a number of treatments, including over-the scope (OVESCO) clip, the patient had intolerance for oral intake and repeated infections.

Reflux-induced esophagitis might facilitate ablation-induced esophageal lesions (ELs) following pulmonary vein isolation (PVI), and these may progress to atrio-esophageal fistula (AEF). In contrast, preexisting ELs are not prone to progression but may affect procedure planning.To study the incidence of preexisting esophageal and upper gastrointestinal (UGI) pathology in patients undergoing PVI, and the relation to ablation-induced ELs.From 08/2018 to 09/2021, consecutive patients undergoing (radiofrequency [RF] or cryoballoon [CB]) PVI were examined by esophagogastroscopy (EGD) before and following ablation. Postprocedural endoscopic ultrasound (EUS) was added in 2021.412 patients (median age 67.5 [IQR 61.3-75.0] years, 56.1% male) were studied. Preprocedural EGD showed abnormalities in 226/399 patients, 15% in the lower third of the esophagus. Half (99/226) were relevant for PVI, 13 procedures were postponed, 6 due to pathological EGD results. A third of the patients with new esophageal injury following ablation had preexisting esophagitis which was associated with a trend for a higher incidence of ELs after RF ablation (12.5 vs. 6.9%, p = 0.232), and a six- and two-fold higher rate of food retention after CB-PVI (28.6 vs. 4.5%, p = 0.008) and RF ablation (8.3 vs. 4.4%, p = 0.279), respectively.(1) EGD before PVI showed UGI abnormalities in 50% of patients, one-fourth of these relevant for PVI. (2) Esophageal inflammation was associated with a higher incidence of post-ablation (peri)-esophageal injury. Whether having this information before ablation is able to reduce ELs or AEF remains to be shown.

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.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.technical success was 95% and clinical success 89%.in our center, esophageal prostheses are a treatment option for fistulas and anastomotic dehiscence after surgery with a high success rate and few complications.

Atrioesophageal fistula (AEF) is an important complication of radiofrequency ablation (RFA). Delayed diagnosis is associated with increased morbidity and mortality. Despite the name “atrioesophageal fistula,” fistulas functionally act esophageal to atrial, which accounts for the neurologic and infectious complications. This report presents the management of a 60-year-old male patient who was admitted to the emergency department (ED) with AEF-caused gastrointestinal bleeding. The patient was operated urgently, but he had serious comorbidities and died after the operation. The aim of this case was to evaluate patients who underwent RFA, within 10 days to two months, carefully in the ED and to know the possible complications.

Esophageal fistulas may occur in an advanced stage or as a potentially life-threatening complication of treatment. They can be divided into esophageal-respiratory and esoph-ageal-aorta fistulas. The diagnosis is confirmed with fluoroscopy using dilute barium oral contrast, followed by thin-section computed tomography, which defines the precise lo-cation and extent of the fistula. Flexible esophagoscopy and bronchoscopy are required for confirmation and anatomic assessment of the suspected fistula and provide additional information for treatment planning. Contamination is traditionally controlled by surgical exclusion, along with a jejunal feeding tube. Currently, fully covered self-expanding metal stents are the primary treatment option.

Background Although there are considerable data on the safety of cryoablation, data on the rare but severe complication of atrioesophageal fistula (AEF) following cryoballoon ablation are limited. Objective To report the global, user-reported incidence of AEF associated with cryoballoon ablation for the treatment of atrial fibrillation using Medtronic’s complaint database. Methods User-reported cryoballoon ablation complications occurring between July 1, 2009, and March 31, 2019, were reviewed to identify cases of AEF. A global event rate of AEF was calculated by dividing the event count by total catheter utilization over the same period. Data on symptoms and patient sequalae were reported as available. Results More than 500,000 Arctic Front cryoballoon catheters (Arctic Front, Arctic Front Advance, Arctic Front Advance ST, and Arctic Front Advance Pro; Medtronic, Inc) were distributed globally during the 9.75-year study period. During this time, 18 confirmed AEF, 1 suspected AEF, and 1 pericardial esophageal fistula were identified; therefore, global incidence of AEF associated with the Arctic Front family of ablation catheters was 0.00396%. Patients most commonly presented with fever (88.2%), and initial symptoms were reported a median of 21 (interquartile range: 4–30) days after the ablation. Although rare, the development of an AEF resulted in death in 68.8% (11/16) of patients with known outcomes. Conclusions AEF is a possible but rare complication of cryoballoon ablation with a reported frequency of 1 in every 25,000 patients treated. Awareness of the prevalence and manifestation of AEF associated with cryoballoon ablation is critical for early identification and treatment of this complication., Graphical abstract

INTRODUCTION The most feared complication of pulmonary vein isolation (PVI) is an atrioesophageal fistula (AEF). While rare (0.1-0.25%), primary surgical closure (as opposed to esophageal stenting) is associated with lower mortality. Pericardioesophageal fistula (PEF) may present prior to fistulization into the atrium. Unfortunately, data on the optimal management of PEFs are lacking. CASE REPORT Seventy-one-year-old male with AF presented with chest pain 3 weeks after radiofrequency PVI. Computed tomography angiography (CTA) chest and echocardiogram showed pneumopericardium. Barium esophagram showed extravasation from esophagus into the pericardium without connection to the left atrium. Sternotomy with mediastinal exploration exposed the pericardial defect, over which a CorMatrix patch was placed. The fistula was then stented endoscopically with endosuture fixation. Poststent esophagram did not show barium leak, and the patient was discharged home. One week later, the patient returned with enterococcal and candida bacteremia and an acute right parietal/occipital lobe infarct. Barium esophagram showed contrast extravasation into the pericardium. The patient rapidly succumbed to his illness and died. Autopsy revealed pericardial abscess posterior to the LA in communication with the esophagus. Extension to the LA was not seen. CONCLUSION While the surgical treatment of AEF is relatively well established, there is no consensus in the management of PEF. While prior small series have suggested PEF may be managed with esophageal stenting, our case illustrates the limitations of this approach.
