RESUMO
BACKGROUND: Oesophageal atresia (OA) is often accompanied by tracheomalacia (TM). The aim of this study was to evaluate its presence in OA patients during routine rigid tracheobronchoscopy (TBS) before primary correction and compare this to postoperative TBS and clinical signs of TM. METHODS: This retrospective cohort study included patients born with OA between June 2013 and December 2022 who had received a TBS before OA correction and had been followed for at least twelve months. Definite TM was postoperatively diagnosed through TBS, and probable TM was defined as having symptoms of TM. RESULTS: We analysed data from 79 patients, of whom 87% with OA type C. Preoperatively, TM was observed in 33 patients (42% of all patients), seven of whom had severe TM. Definite TM was observed in 21 patients (27%), of whom 15 had severe TM. Forty-one patients (52% of all patients) had developed symptoms of TM within twelve months, including harsh barking cough (n = 15), stridor and/or wheezing (n = 20), recurrent respiratory insufficiency (n = 11), or needing airway surgery (n = 7). The sensitivity of preoperative TBS for the presence of postoperative (definite and probable combined) TM is 50.0%, 95% CI [35.2-64.8], and the specificity 67.6%, 95% CI [51.7-81.1]. Clinical characteristics did not differ between the patients with or without postoperative TM. CONCLUSIONS: More than half of the studied patients with OA experienced symptoms of TM. While preoperative TBS is routinely performed prior to surgical OA correction, its predictive value for the presence of postoperative TM remains limited. LEVEL OF EVIDENCE: Level II. TYPE OF STUDY: Study of Diagnostics Test.
RESUMO
Atrial-esophageal fistulas are rare and potentially fatal complications that can occur from radiofrequency ablation for the treatment of atrial fibrillation. Due to the proximity of the right atrium to the esophagus, thermal injuries can involuntarily lead to connections between the heart and esophagus. In this case study, a 67-year-old male developed an atrial-esophageal fistula following atrial fibrillation ablation. After discharge, the patient first presented with melena with a range of complications including aspiration, fever, atrial fibrillation, and neurological symptoms. The fistula was repaired promptly after diagnosis requiring meticulous planning by the anesthesia and surgical teams. The major consideration from anesthesiology was providing adequate oxygenation during one-lung ventilation via continuous positive airway pressure on the non-dependent lung. This case also highlights the need for recognizing and managing potential complications associated with catheter ablation procedures. A thorough understanding of these rare but critical events is essential for optimizing patient outcomes and minimizing mortality rates, and physicians and healthcare professionals must remain vigilant regarding such complications.
RESUMO
Key Clinical Message: In patients with poorly controlled diabetes, early recognition of rare fungal infections like pulmonary mucormycosis, especially when presenting with unusual complications such as broncho-esophageal fistula, is critical. Prompt intervention with antifungal therapy and consideration for surgical debridement significantly impact outcomes. Multidisciplinary management is paramount for such complex cases. Abstract: Mucormycosis is a rare fungal infection caused by the Mucorales. This infection is mostly observed among those with poorly controlled diabetes or immunodeficiency. The most common presentation of the infection among those with poorly controlled diabetes is rhino-orbit-cerebral involvement. In this case report, we provide the history and outcome of a rare case of pulmonary mucormycosis in a patient with poorly controlled diabetes who was simultaneously diagnosed with broncho-esophageal fistula. Our patient was a 32-year-old male with a history of poorly controlled diabetes. Over the months, he had complained of productive coughs and dyspnea, which had lately been joined by dysphagia. He also claimed to have lost considerable weight (10 kg) during the previous 3 months. Barium swallow showed an abnormal flow of contrast between the bronchus and esophagus, suggesting a broncho-esophageal fistula. Computed tomography of the thorax revealed a broncho-esophageal fistula between the left main bronchus (LMB) and esophagus. He had a bronchoscopy the next day, which revealed necrosis and a broncho-esophageal fistula in the LMB. A bronchial biopsy showed typical hyphae with necrotic tissue, indicating mucormycosis. The patient's antimycotic medication (liposomal amphotericin) was started and a prompt surgery consult was ordered. The patient, however, passed away from massive hemoptysis. We described a rare case of pulmonary mucormycosis with broncho-esophageal fistula in a patient with poorly controlled diabetes. The rarity of this combination highlights the associated diagnostic and treatment hurdles. Early detection, antifungal medication, as soon as possible surgical debridement of involved tissues, and a multidisciplinary approach could improve patient outcomes.
RESUMO
BACKGROUND: Catheter ablation for atrial fibrillation (AF) including pulmonary vein isolation and possibly further substrate ablation is the most common electrophysiological procedure. Severe complications are uncommon, but their detailed assessment in a large worldwide cohort is lacking. OBJECTIVES: The aim of this study was to determine the incidence of periprocedural severe complications and to provide a detailed characterization of the diagnostic evaluation and management of these complications in patients undergoing AF ablation. METHODS: Individual patient data were collected from 23 centers worldwide. Limited data were collected for all patients who underwent catheter ablation, and an expanded series of data points were collected for patients who experienced severe complications during periprocedural follow-up. Incidence, predictors, patient characteristics, management details, and overall outcomes of patients who experienced ablation-related complications were investigated. RESULTS: Data were collected from 23 participating centers at which 33,879 procedures were performed (median age 63 years, 30% women, 71% radiofrequency ablations). The incidence of severe complications (n = 271) was low (tamponade 6.8, stroke 0.97, cardiac arrest 0.41, esophageal fistula 0.21, and death 0.21). Age, female sex, a dilated left atrium, procedure duration, and the use of radiofrequency energy were independently associated with the composite endpoint of all severe complications. Among patients experiencing tamponade, 13% required cardiac surgery. Ninety-three percent of patients with complications were discharged directly home after a median length of stay of 5 days (Q1-Q3: 3-7 days). CONCLUSIONS: This large worldwide collaborative study highlighted that tamponade, stroke, cardiac arrest, esophageal fistula, and death are rare after AF ablation. Older age, female sex, procedure duration, a dilated left atrium, and the use of radiofrequency energy were associated with severe complications in this multinational cohort. One in 8 patients with tamponade required cardiac surgery.

Broncho-esophageal fistula (BEF) is a severe yet relatively rare connection between the bronchus and esophagus usually caused by esophageal and pulmonary malignancies. We present a case report of a 49-year-old man diagnosed with terminal lung carcinoma who developed a BEF. The thoracic computed tomography scan detected a mass in the left bronchi that partially covers and disrupts the bronchial contour in certain regions and extends to the esophageal wall. After thoroughly evaluating alternative treatment approaches, we opt for the stenting procedure due to the advanced stage of the tumor and the significantly diminished quality of life. The treatment involves the use of a partially covered metal stent that is known to exhibit lower potential to migrate. The treatment is highly successful, resulting in a significant enhancement of the patient's quality of life, a lengthening in his survival, and the ability to pursue additional palliative treatment options. In contrast to the typical prosthesis implantation, our procedure uses a direct endoscopic visualization for the proximal deployment of a partially covered stent, offering a cost-effective and radiation-free alternative that can be particularly beneficial for BEF patients in facilities without radiology services.

PURPOSE: This study aims to evaluate different surgical approaches to long-gap esophageal atresia (LGEA) with or without tracheoesophageal fistula (TEF) is unclear. METHODS: A systematic literature review was done comparing gastric transposition versus esophageal lengthening with delayed primary anastomosis in infants with LGEA+/-TEF. The primary outcome was time to full oral feeds. Secondary outcomes were time to full enteric feeds, need for further surgery, growth, mortality, and postoperative adverse events. RESULTS: No comparative studies were found. However, the literature was re-interrogated for non-comparative studies. Four hundred thirty-eight articles were identified and screened, and 18 met the inclusion criteria. All were case series. Forty-three infants underwent gastric transposition, and 106 had esophageal lengthening with delayed primary anastomosis. One study on gastric transposition reported time to full oral feeds, and one study in each group reported growth. Time to full enteric feeds was reported in one study in each group. 30% of infants had further surgery following gastric transposition, including hiatus hernia repair (5/43, 12%) and esophageal dilation (7/43, 16%). Following esophageal lengthening, 62/106 (58%) had anti-reflux surgery, 58/106 (55%) esophageal dilatation and 11/106 (10%) esophageal stricture resection. Anastomotic complications occurred in 13/43 (30%), gastrointestinal in 16/43 (37%), respiratory in 17/43 (40%), and nerve injury in 2/43 (5%) of the gastric transposition group. In the esophageal lengthening group, anastomotic complications occurred in 68/106 (64%), gastrointestinal in 62/106 (58%), respiratory in 6/106 (6%), and none sustained nerve injury. Each group had one death due to a cause not directly related to the surgical procedure. CONCLUSIONS: This systematic review highlights the morbidity associated with both surgical procedures and the variety in reporting outcomes.

Background: Esophageal fistula (EF) is a serious adverse event as a result of radiotherapy in patients with esophageal cancer (EC). We aimed to identify the predictive factors and establish a prediction model of EF in patients with esophageal squamous cell carcinoma (ESCC) who underwent intensity-modulated radiation therapy (IMRT) or volumetric-modulated arc therapy (VMAT). Methods: Patients with ESCC treated with IMRT or VMAT from January 2013 to December 2020 at Xijing Hospital were retrospectively analyzed. Ultimately, 43 patients with EF and 129 patients without EF were included in the analysis and propensity-score matched in a 1:3 ratio. The clinical characteristics and radiomics features were extracted. Univariate and multivariate stepwise logistic regression analyses were used to determine the risk factors associated with EF. Results: The median follow-up time was 24.0 months (range, 1.3-104.9 months), and the median overall survival (OS) was 13.1 months in patients with EF. A total of 1,158 radiomics features were extracted, and eight radiomics features were selected for inclusion into a model for predicting EF, with an area under the receiver operating characteristic curve (AUC) value of 0.794. Multivariate analysis showed that tumor length, tumor volume, T stage, lymphocyte rate (LR), and grade IV esophagus stenosis were related to EF, and the AUC value of clinical model for predicting EF was 0.849. The clinical-radiomics model had the best performance in predicting EF with an AUC value of 0.896. Conclusions: The clinical-radiomics nomogram can predict the risk of EF in ESCC patients and is helpful for the individualized treatment of EC.

Boerhaave's syndrome is a potentially fatal emergency, typically induced by forceful retching, which leads to increased intra-esophageal pressure. It commonly presents with vague symptoms such as chest pain or more classic symptoms like subcutaneous emphysema and vomiting. We present an unusual case of Boerhaave syndrome secondary to rapid and excessive intake of carbonated drinks in a 22-year-old male, who presented to our emergency department with atypical symptoms of fever and shortness of breath. Imaging studies showed left-sided hydropneumothorax with an esophageal pleural fistula, and multidisciplinary teams were involved in the patient's management.
RESUMO
Aorto-esophageal fistula (AEF) due to esophageal cancer (EC) is a life-threatening condition characterized by sudden hemorrhage, which often causes sudden death. To evaluate the efficacy and safety of thoracic endovascular aortic repair (TEVAR) for AEF due to EC, we performed a systematic review and meta-analysis. We searched the MEDLINE (PubMed) databases, the Cochrane Library databases, Ichushi-Web (the databases of the Japan Medical Abstract Society), and CiNii (Academic information search service of the National Institute of Information from Japan) from January 2000 to November 2023 for articles about TEVAR for an emergent aortic hemorrhage (salvage TEVAR [S-TEVAR]), and the prophylactic procedure (P-TEVAR). Six studies (140 cases) were eligible for meta-analysis. The 90-day mortality of S-TEVAR and P-TEVAR was 40% (95% CI 23-60, I2 = 36%) and 8% (95% CI 3-17, I2 = 0%), respectively. Post-S-TEVAR hemorrhagic and infectious complications were 17% (95% CI 3-57, I2 = 71%) and 20% (95% CI 5-57, I2 = 66%), respectively. Post-P-TEVAR hemorrhagic and infectious complications were 2% (95% CI 0-10, I2 = 0%) and 3% (95% CI 1-12, I2 = 0%), respectively. TEVAR for AEF due to EC may be a useful therapeutic option to manage or prevent hemorrhagic oncological emergencies.

PURPOSE: To develop and internally validate a novel prediction score to predict the occurrence of arterial-esophageal fistula (AEF) in esophageal cancer bleeding. METHODS: This retrospective cohort study enrolled patients with esophageal cancer bleeding in the emergency department. The primary outcome was the diagnosis of AEF. The patients were randomly divided into a derivation group and a validation group. In the derivation stage, a predictive model was developed using logistic regression analysis. Subsequently, internal validation of the model was conducted in the validation cohort during the validation stage to assess its discrimination ability. RESULTS: A total of 257 patients were enrolled in this study. All participants were randomized to a derivation cohort (n = 155) and a validation cohort (n = 102). AEF occurred in 22 patients (14.2%) in the derivation group and 14 patients (13.7%) in the validation group. A predictive model (HEARTS-Score) comprising five variables (hematemesis, active bleeding, serum creatinine level >1.2 mg/dL, prothrombin time >13 s, and previous stent implantation) was established. The HEARTS-Score demonstrated a high discriminative ability in both the derivation and validation cohorts, with c-statistics of 0.90 (95% CI 0.82-0.98) and 0.82 (95% CI 0.72-0.92), respectively. CONCLUSIONS: By employing this novel prediction score, clinicians can make more objective risk assessments, optimizing diagnostic strategies and tailoring treatment approaches.
RESUMO
BACKGROUND: Broncho-esophageal fistula (BEF) secondary to esophageal diverticulum is a rare clinical condition, which is often misdiagnosed for a long time. The aim of our study is to summarize and clarify the advantages of MSCT in diagnosing BEF secondary to esophageal diverticulum. METHODS: We retrospectively analyzed patients clinically diagnosed with BEF from January 2005 to January 2022 at Jilin University First Hospital. Only those patients with BEF secondary to esophageal diverticulum and complete clinical data met our enrolled standard. All patients' clinicopathologic characteristics and MSCT features were systemically evaluated. RESULTS: 17 patients were eligible for our cohort study, including male 10 and female 7. The patient's mean age was 42.3 ± 12.5. The chronic cough occurred in all seventeen patients and bucking following oral fluid intake was documented in nine patients. MSCT distinctly suggested the fistulous tract between the bronchi and the esophagus in all patients. The mean diameter of the orifices in the wall of the esophagus was 4.40 ± 1.81 mm. The orifice in the midthoracic esophagus side was 15 cases and 2 cases at the lower thoracic esophagus. The involved bronchus included 13 cases at the right lower lobe bronchus, 1 at the right middle lobe bronchus and 3 at the left lower lobe bronchus. The contrast agent was observed in the pulmonary parenchyma in 10 of 13 patients who underwent esophagogram. No definite fistula was observed in 3 of 11 who underwent gastroscopy, while the intra-operative findings supported the existence of fistula. CONCLUSIONS: BEF secondary to esophageal diverticulum tends to occur between the midthoracic esophagus and the right lower lobe bronchus. Compared with esophagography and gastroscopy, MSCT shows more comprehensive information about the fistulous shape, size, course and lung involvement, which are helpful for establishing diagnosis and guiding subsequent treatment.

Objective: To evaluate outcomes of surgical repair of postesophagectomy neoesophagus-airway fistulas (NEAFs). Methods: We retrospectively included consecutive patients with NEAF managed by various techniques at our center between August 2009 and July 2021. Result: Of the 11 patients (median age, 60 years; interquartile range, 58, 62), 4 had received induction chemoradiotherapy and 4 others induction chemotherapy. NEAF was mainly a complication of anastomotic leakage (n = 6) or attempted stenosis treatment (n = 3). The airway mainly involved was the trachea (n = 8). Airway defects were repaired by resection-anastomosis (n = 5), perforator flaps (n = 4), pedicled pericardium (n = 1), and/or direct suturing (n = 2). Gastric conduit defects were repaired by perforator flaps (n = 6), direct suturing (n = 2), or pedicled pericardium (n = 1). Of the 7 perforator flaps, 4 were internal mammary-artery, two dorsal intercostal-artery, and one supraclavicular-artery flaps. After a median follow-up of 100 months, 2 patients died on early postoperative course from NEAF repair failure and 3 from late NEAF recurrence at 4, 11, and 33 months. Among the remaining 6 patients, 1 died from local tumoral recurrence at 13 months, 1 was last on follow-up at 27 months, alive and eating normally. The other 4 were free from NEAF recurrence and dysphagia or swallowing disorder at 50 months' follow-up. These 4 results were obtained thanks to perforator flap interposition and airway resection anastomosis. Conclusions: Surgical NEAF repair using perforator flap interposition may provide satisfactory long-term function after strong prehabilitation.
RESUMO
We discuss the case of an esophageal cancer patient treated by chemo and radiotherapy complicated by an esophageal stenosis and an iatrogenic broncho-esophageal fistula. This latter was managed with multiple palliative stenting procedures and colonic surgical bypass. Despite a long disease free survival but decreased quality of life and frailty, we came to the proposal of an extremely unusual form of treatment - physiological lung exclusion, with clinical benefit and so far without any drawbacks related to the procedure.

OBJECTIVE: This study aimed to develop a prediction model for esophageal fistula (EF) in esophageal cancer (EC) patients treated with intensity-modulated radiation therapy (IMRT), by integrating multi-omics features from multiple volumes of interest (VOIs). METHODS: We retrospectively analyzed pretreatment planning computed tomographic (CT) images, three-dimensional dose distributions, and clinical factors of 287 EC patients. Nine groups of features from different combination of omics [Radiomics (R), Dosiomics (D), and RD (the combination of R and D)], and VOIs [esophagus (ESO), gross tumor volume (GTV), and EG (the combination of ESO and GTV)] were extracted and separately selected by unsupervised (analysis of variance (ANOVA) and Pearson correlation test) and supervised (Student T test) approaches. The final model performance was evaluated using five metrics: average area under the receiver-operator-characteristics curve (AUC), accuracy, precision, recall, and F1 score. RESULTS: For multi-omics using RD features, the model performance in EG model shows: AUC, 0.817 ± 0.031; 95% CI 0.805, 0.825; p < 0.001, which is better than single VOI (ESO or GTV). CONCLUSION: Integrating multi-omics features from multi-VOIs enables better prediction of EF in EC patients treated with IMRT. The incorporation of dosiomics features can enhance the model performance of the prediction.

BACKGROUND: Atrial esophageal fistula (AEF) is a lethal complication that can occur post atrial fibrillation (AF) ablation. Esophageal injury (EI) is likely to be the initial lesion leading to AEF. Endoscopic examination is the gold standard for a diagnosis of EI but extensive endoscopic screening is invasive and costly. This study was conducted to determine whether fecal calprotectin (Fcal), a marker of inflammation throughout the intestinal tract, may be associated with the existence of esophageal injury. METHODS: This diagnostic study was conducted in a cohort of 166 patients with symptomatic AF undergoing radiofrequency catheter ablation from May 2020 to June 2021. Fcal tests were performed 1-7 days after ablation. All patients underwent endoscopic ultrasonography 1 or 2 days after ablation. RESULTS: The levels of Fcal were significantly different between the EI and non-EI groups (404.9 µg/g (IQR 129.6-723.6) vs. 40.4 µg/g (IQR 15.0-246.2), p < .001). Analysis of ROC curves revealed that a Fcal level of 125 µg/g might be the optimal cut-off value for a diagnosis of EI, giving a 78.8% sensitivity and a 65.4% specificity. The negative predictive value of Fcal was 100% for ulcerated EI. CONCLUSIONS: The level of Fcal is associated with EI post AF catheter ablation. 125 µg/g might be the optimal cut-off value for a diagnosis of EI. Negative Fcal could predict the absence of ulcerated EI, which could be considered a precursor to AEF.

An aorto-esophageal fistula (AEF) is a rare complication of aortic surgery but can cause potentially lethal upper gastrointestinal tract bleeding. A patient presented with an AEF secondary to emergency endovascular repair of a contained penetrating atherosclerotic ulcer rupture of the thoracic aorta and was successfully treated with endoscopic closure using fibrin glue. As endovascular repair becomes increasingly common, a greater incidence of AEFs should be anticipated and the treatment options better described.
