Tracheoarterial fistula in a patient with amyotrophic lateral sclerosis successfully managed by overinflation of the tracheostomy tube cuff alone: a case report.

BACKGROUND: Tracheoarterial fistula is the most devastating complication after tracheostomy, and its mortality, without definitive treatment, approaches 100%. In general, the combination of bedside emergency management, that is, overinflation of the tracheostomy tube cuff, and definitive treatment such as surgical or endovascular intervention is necessary to prevent the poor outcome. Patients with neuromuscular diseases such as amyotrophic lateral sclerosis are susceptible to tracheoarterial fistula because of long-term mechanical ventilation and muscle weakness. CASE PRESENTATION: We describe a case of tracheoarterial fistula in a Japanese 39-year-old patient with amyotrophic lateral sclerosis with long-term ventilator management. The patient was clinically diagnosed with a tracheoarterial fistula because of massive bleeding following sentinel hemorrhage. The massive hemorrhage was controlled by overinflation of the tracheostomy tube cuff alone, without definitive treatment. CONCLUSIONS: This case suggests overinflation of the tracheostomy tube cuff alone plays an important role, semi-permanently, in the management of tracheoarterial fistula, especially in cases where surgical or endovascular intervention is not indicated. Clinicians taking care of patients with tracheostomy undergoing long-term mechanical ventilation should be aware that tracheoarterial fistula might occur following tracheostomy.

Outcomes and complications of simple layered closure of persistent tracheocutaneous fistula after tracheostomy in childhood.

BACKGROUND: Up to half of all children who have a tracheostomy will develop a persistent tracheo-cutaneous fistula (TCF) after decannulation. Surgical closure of the TCF is technically easy but post-operative complications can be immediate and life-threatening. These include air leak from the tracheal repair leading to massive surgical emphysema or pneumothorax. We reviewed our experience of TCF closure to try to identify potential risk factors for complications. METHOD: Retrospective case record review of all children (0-16 years) who underwent surgical TCF closure between January 2010 and December 2021 following development of a persistent TCF after decannulation of a tracheostomy. RESULTS: We identified 67 children. They ranged in age from 14 months to 16 years (median 3 years 10 months) at the time of the TCF closure. Major medical comorbidities were present in 90%. Pre-operative pulse oximetry with the fistula occluded was used in 29 children (43%). An underwater leak test was performed in 28 (42%). A non-suction drain was used in 29 children (43%). Prophylactic antibiotics were prescribed for 30 children (45%). Post-operative complications occurred in 15 children (22%). Life-threatening air leak occurred in the immediate post-operative period in 2 children (3%). Respiratory distress occurred in 3 children (4%) in the recovery area immediately after surgery. None required re-tracheostomy. Three children suffered post-operative pneumonia (4%), and wound infections occurred in 8 children (12%). We were unable to show a significant association between patient or surgical factors and complications. DISCUSSION: Complications for TCF closure are unfortunately common and it is unclear from the available evidence how best to prevent them. Further research is required.

Esophageal Pulmonary-splenopancreatic Fistula: A Serious Complication of Sleeve Gastrectomy.

Esophagopulmonary fistulas are exceedingly rare and require surgical debridement and repair or diversion to prevent overwhelming sepsis. Fistulas that cross the diaphragm are even rarer. This report describes the case of a patient with an iatrogenic esophageal perforation after sleeve gastrectomy that was never managed definitively and in whom an esophagopulmonary-splenopancreatic fistula developed. The patient underwent an esophagectomy with esophagojejunostomy and distal pancreaticosplenectomy for management of the fistula. This case presents a rare complication of sleeve gastrectomy and highlights the need for early definitive management of esophageal perforations.

Novel Use of the Buccal Fat Pad for Sinocutaneous Fistulae Closure and a Review of Reconstructive Options.

BACKGROUND: Sinocutaneous fistulae (SCF) are abnormal communications between the paranasal sinuses and the overlying skin. They may be difficult to manage due to facial geometry, scar contraction, and poor tissue vascularity. We describe a novel use of the buccal flap and review the literature to examine management options for this disease process. METHODS: A PubMed/MEDLINE literature search was performed for studies published between January 1, 1950 and April 29, 2020 that describe management strategies for SCF. The clinical record, imaging, and operative reports were reviewed of the case in which the buccal fat flap was used in reconstruction. RESULTS: A total of 359 articles were retrieved. After removing duplicate articles, non-English studies, animal studies, duplicate articles and studies that mentioned SCF without specific mention of management strategies, 51 articles were reviewed. Management paradigms throughout the articles include (1) removal of infection, (2) ensuring patency of sinus outflow tracts, (3) tensionless multilayered closure using well vascularized tissue, and (4) prevention or minimization of future risk factors for fistula formation. CONCLUSION: This article informs surgeons on reconstructive options for sinocutaneous fistulae including a novel description of the buccal fat flap.

Endobronchial valve positioning for alveolar-pleural fistula following ICU management complicating COVID-19 pneumonia.

BACKGROUND: The main clinical consequences of severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) infection are pneumonia and respiratory failure even requiring mechanical ventilation. In this context, the lung parenchyma is highly prone to ventilator-related injury, with pneumothorax and persistent air leak as the most serious adverse events. So far, endobronchial valve (EBV) positioning has proved efficacious in treating air leaks with a high success rate. CASE PRESENTATION: We report, for the first time, two cases of patients affected by SARS-CoV-2-related pneumonia complicated with bacterial super-infection, experiencing pneumothorax and persistent air leaks after invasive mechanical ventilation. Despite the severity of respiratory failure both patients underwent rigid interventional bronchoscopy and were successfully treated through EBV positioning. CONCLUSIONS: Persistent air leaks may result from lung tissue damage due to a complex interaction between inflammation and ventilator-related injury (VILI), especially in the advanced stages of ARDS. EBV positioning seems to be a feasible and effective minimally invasive therapeutic option for treating this subset of patients.

Post-tracheostomy tracheoinnominate fistula: endovascular treatment.

OBJECTIVE: Tracheoinnominate fistula (TIF) is a rare and frequently lethal complication of tracheostomies. Immediate bleeding control and surgical treatment are essential to avoid death. This report describes the successful endovascular treatment of TIF in a preschooler and reviews the literature concerning epidemiology, diagnosis, prophylaxis, and treatment of TIF in pediatric patients. CASE DESCRIPTION: A tracheostomized neurologically impaired bed-ridden three-year-old girl was admitted to treat an episode of tracheitis. Tracheostomy had been performed two years before. The child used a plastic cuffed tube continually inflated at low pressure. The patient presented two self-limited bleeding episodes through the tracheostomy in a 48h interval. A new episode was suggestive of arterial bleeding, immediately leading to a provisional diagnosis of TIF, which was confirmed by angiotomography, affecting the bifurcation of the innominate artery and the right tracheal wall. The patient was immediately treated by the endovascular placement of polytetrafluoroethylene (PTFE)/nitinol stents in Y configuration. No recurrent TIF, neurological problems, or right arm ischemia have been detected in the follow-up. COMMENTS: TIF must be suspected after any significant bleeding from the tracheostoma. Endovascular techniques may provide rapid bleeding control with low morbidity, but they are limited to a few case reports in pediatric patients, all of them addressing adolescents. Long-term follow-up is needed to detect whether stent-related vascular complications will occur with growth.

Regional pedicled flaps in prevention and repair of pharyngocutaneous fistulas.

BACKGROUND: Pharyngocutaneous fistula (PCF) is a common complication after laryngopharyngeal surgery. It presents incredible difficulties to both doctors and patients and can lead to prolonged hospitalization. OBJECTIVE: To analyze the pros and cons of the pedicled skin flap in the prevention and repair of PCF and put forward the authors' views and experience about the selection and application of flaps for the treatment of PCF. METHODS: A literature review of pedicled flap application in PCF was carried out. RESULTS: Based on the analysis of the characteristics of the pedicled flap in PCF treatment, the advantages and disadvantages are compared. RESULTS: In the literature, the pectoralis major myocutaneous flap is the most widely used regional pedicled flap for PCF. Many other flaps can be used to prevent and treat PCF. Each kind of pedicled flap has advantages and limitations. This plays a role in the individualized selection and design of PCF to maximize the benefits of patients. CONCLUSIONS: Taking unity of function, aesthetics, and proficiency of operators into account, choosing the appropriate flap to repair PCF can reduce the occurrence rate of PCF and improve the patient's quality of life.

Aortotracheal fistula after slide tracheoplasty in a patient with dextrocardia, left pulmonary artery sling and tracheal stenosis: a case report.

BACKGROUND: Aortotracheal fistula (ATF) is an uncommon and fatal complication of tracheal or aortic surgery, especially among pediatric patients. CASE PRESENTATION: We reported a case in a 1-year-old boy with dextrocardia, left pulmonary artery sling and long segment tracheal stenosis. He received slide tracheoplasty at 9 months of age and had post-operative refractory granulation at distal trachea status post repeated balloon dilatation and laser vaporization. Episodes of hemoptysis occurred on post-operative day 81. Bronchoscopy revealed a pulsating pseudoaneurysm at lower trachea which ruptured during the procedure Urgent surgical repair under cardiopulmonary bypass with deep hypothermic circulatory arrest was done. No recurrent bleeding or significant neurologic deficits noticed at a 4-month follow-up. CONCLUSION: Congenital anomaly that changes the spatial relationship between trachea and aorta could have contributed to formation of ATF. This warrant future attention when managing tracheal granulation with this not uncommon anatomy.

Innovative method for Amplatzer device implantation in patients with bronchopleural fistulas.

BACKGROUND: Bronchopleural fistula (BPF) is a relatively rare complication after various types of pulmonary resection. The double-sided mushroom-shaped occluder (Amplatzer device, AD) has been gradually used for BPF blocking due to its reliable blocking effect. We have improved the existing AD implantation methods to facilitate clinical use and named the new approach Sheath-free method (SFM). The aim of the present report was to explore the reliability and advantages of the SFM in AD implantation. METHODS: We improved the existing implantation methods by abandoning the sheath of the AD and using the working channel of the bronchoscope to directly store or release the AD without general anesthesia, rigid bronchoscopy, fluoroscopy, or bronchography. A total of 6 patients (5 men and 1 woman, aged 66.67 ± 6.19 years [mean ± SD]) had BPF blocking and underwent the SFM in AD implantation. RESULTS: AD implantation was successfully performed in all 6 patients with the SFM, 4 persons had a successful closure of the fistula, one person died after few days and one person did not have a successful closure of the fistula. The average duration of operation was 16.17 min (16.17 ± 4.67 min [mean ± SD]). No patients died due to operation complications or BPF recurrence. The average follow-up time was 13.2 months (range 10-17 months). CONCLUSION: We observed that the SFM for AD implantation-with accurate device positioning and a clear field of vision-is efficient and convenient. The AD is effective in BPF blocking, and could contribute to significantly improved symptoms of patients.

Effectiveness and safety of a newly designed partially covered tracheal metallic Y-shaped stent for the treatment of high cervical gastro-tracheal or tracheo-esophageal fistula: A retrospective observational study.

ABSTRACT: The aim of this study was to evaluate the effectiveness and safety of a partially covered metallic tracheal Y-shaped stent for the treatment of high cervical gastro-tracheal fistula (GTF) and tracheo-esophageal fistula (TEF). From January 2017 to January 2019, 16 patients with high cervical GTF and TEF received partially covered metallic Y-shaped stent placement under fluoroscopic guidance. The technical and clinical success rates, incidence of major complications, and survival outcomes were analyzed. Eastern Cooperative Oncology Group (ECOG) score and quality of life (SF-36 questionnaire) were compared pre and post stent placement. Technical and clinical success rates were 100% and 81.3%, respectively. Major complications (severe tumor ingrowth, mucostasis, hyperplastic granulation tissue) occurred in 7/16 (43.8%) patients. ECOG score and 5 of the 8 domains of the SF-36 (physical function, role physical, general health, vitality, social function) were significantly improved at 1 month after treatment (P < .01). During the median follow-up period of 8.3 months, 9 patients were alive. Median overall survival was 10.3 months (95% CI, 8.0-12.6). The newly designed partially covered tracheal Y-shaped stent appears to be effective and safe for treatment of high cervical GTF and TEF.

Evaluation of Endovascular Intervention for Tracheo-Innominate Artery Fistula: A Systematic Review.

BACKGROUND: While the standard of care for suspected tracheo-innominate artery fistula (TIF) necessitates sternotomy, perioperative mortality remains high. Endovascular interventions have been attempted, but reports have been anecdotal. The aim of this systematic review was to evaluate the outcomes of endovascular management of TIF by pooling the existing evidence. METHODS: An electronic database search of Ovid MEDLINE, Scopus, Cumulative Index to Nursing and Allied Health Literature, and Cochrane Controlled Trials Register was performed to identify all studies examining endovascular treatment of TIF. Patients greater than 14 years of age who underwent endovascular intervention for TIF were included. 25 studies consisting of 27 patients met the inclusion criteria. RESULTS: 48.1% (13/27) of patients were male and median age was 39.0 [IQR 16.0, 47.5] years. Tracheostomy was present in 96.3% (26/27) of cases. Median duration from tracheostomy to TIF presentation was 2.2 months [0.5, 42.5]. On presentation, 84.6% (22/26) had tracheal hemorrhage, and 22.8% (6/27) were hemodynamically unstable. 96.3% (26/27) underwent covered stent graft placement while 1 patient (3.8%) had coil embolization. 18.5% (5/27) of patients required repeat endovascular intervention for recurrent bleeding, while 11.1% (3/27) required rescue sternotomy. Median hospital length of stay was 30 days [16.0, 46.5], and overall mortality was 29.6% (8/27) with a median follow-up time of 5 months [1.2, 11.5]. CONCLUSION: While uncommon, endovascular treatment of TIF may be a feasible alternative to sternotomy. The approach may be useful in those who are unable to undergo surgery or are likely to have adhesions from prior chest operations.

3D Printed Fistula Plug: A Novel Bridge to Definitive Reconstruction.

A case is presented showcasing the feasibility of three-dimensional (3D) printing patient-specific fistula plugs as a bridge therapy to definitive management of pharyngocutaneous fistulae. For this patient, a set of 3D printed fistula plugs was successfully used with low morbidity and positive results in the management of this postoperative issue. Utilizing 3D printed fistula plugs could represent a novel yet safe therapy for patients requiring long-term management of similar wounds. Further studies are warranted to evaluate implementation of this practice on a widespread scale. Laryngoscope, 131:111-114, 2021.

Case report: the thoracoscopic surgery in peritoneal-pleural leakage. A valid therapeutic strategy.

Pleuro-peritoneal leakage is an uncommon complication of peritoneal dialysis (PD). In this study, we report the case of a male patient (age 83), treated with PD (daytime single-exchange). In October 2019, hospitalization was necessary due to dyspnoea and a reduction of peritoneal ultrafiltration. A right pleural leakage resulted at chest x-ray. A regression of the pleural leakage was immediately observed after interrupting PD. It was then performed a pleuro-peritoneal CT scan at baseline, followed by a second scan performed 4 hours after the injection of 2 L of isotonic solution with 100ml of contrast medium, which evidenced a pleuro-peritoneal communication. It was then decided to perform a video-assisted thoracoscopic surgery (VATS), that showed no evidence of diaphragm communication. It was then executed a pleurodesis using sterile talcum. The patient was released on the 3rd day, with a conservative therapy and a low-protein diet. After 2 weeks a new pleuro-peritoneal CT scan with contrast medium was executed. This time the scan evidenced the absence of contrast medium in the thoracic cavity. The patient then resumed PD therapy, with 3 daily exchanges with isotonic solution (volume 1.5 L), showing no complications. Concerning the treatment of pleuro-peritoneal leakage, VATS allows both the patch-repairing of diaphragmatic flaws and the instillation of chemical agents. In our case, VATS allowed the chemical pleurodesis which in turn enabled, in just 2 weeks of conservative treatment, the resuming of PD. In conclusion, this methodology is a valid option in the treatment of pleuro-peritoneal leakage in PD patients.

[Endoscopic bronchial valve treatment of bronchopleural fistala and air leakage]. / Endoskopicheskaya klapannaya bronkhoblokatsiya pri lechenii bronkhoplevral'nykh svishchei i utechki vozdukha.

OBJECTIVE: To evaluate an effectiveness of endobronchial valve treatment of patients with bronchopleural fistulas and prolonged air leakage. MATERIAL AND METHODS: Endobronchial valve treatment was analyzed in 115 patients with bronchopleural fistulas or postoperative air leakage. All patients were divided into 5 groups depending on disease: bullous emphysema, acute purulent lung diseases, chronic purulent lung and pleural diseases, bullous emphysema complicated by pneumothorax with failed pleural cavity, other lung diseases associated with prolonged postoperative air leakage. RESULTS: Endobronchial valve treatment was effective in more than 70% patients. There were no intraoperative and postoperative complications. CONCLUSION: Endobronchial valve treatment is a highly effective minimally invasive method for treating patients with bronchopleural fistulas and postoperative air leakage.

Endoscopic management of pancreaticopleural fistula in a pediatric patient: A case report and literature review.

INTRODUCTION: Pancreaticopleural fistula (PPF) is a rare but serious complication of pancreatic disorders. As the clinical presentations of PPF are often deceptive, it can cause a delay in the timely diagnosis and proper treatment. PPF is extremely uncommon in pediatric patients, and diagnostic and management strategies for PPF among pediatric patients are scanty. PATIENT CONCERNS: A 12-year-old girl presented with cough and dyspnea owing to massive right-side pleural effusion confirmed by Chest X-ray. Biochemical examination of pleural effusion revealed a significant elevation of amylase level. Imaging modalities showed dilated pancreatic duct and fistulous tract connecting pancreatic duct and right thorax. DIAGNOSIS: Chronic pancreatitis with PPF was diagnosed. INTERVENTIONS: Medical therapy was initially attempted for 2 weeks. Endoscopic therapy with naso-pancreatic drainage tube placement was then performed without any complications after failed medical therapy. OUTCOMES: The patient has remained healthy and symptom-free during 2 years of follow-up. CONCLUSION: When pediatric patients presented with recurrent pleural effusion with unknown etiology, PPF should be taken into consideration. Pleural effusion amylase level is the most important laboratory test and magnetic resonance cholangiopancreatography is recommended to visualize the fistula. Optimal management of PPF should be based on pancreatic duct morphology.

The treatment of congenital pyriform sinus fistula: a single-center experience.

PURPOSE: Congenital pyriform sinus fistula (CPSF) often presents diagnosis and treatment challenges. This study aimed to explore the treatment principles and to evaluate the effectiveness of the hypothermia plasma cauterization with suspension laryngoscopy for CPSF. METHODS: The medical records of 56 patients with CPSF from January 2000 to December 2019 were retrospectively reviewed. RESULTS: Of the 56 cases, the lesions were predominantly located on the left side (95%), and the accuracy of the first diagnosis was 30%. Ultrasound showed an abnormal rate of 86%, while CT or MRI displayed an abnormal anatomic lesion of 92%. The 3D visual reconstruction enabled the analysis of morphological characteristics of CPSF. The positive predictive value of barium esophagography was 89%, whereas the positive rate of the internal opening in CPSF under local anesthesia laryngoscopy was 33%. Nine cases of sinus type underwent open resection, and the recurrence rate was 33%. Interestingly, ten patients with sinus type underwent hypothermia plasma cauterization with suspension laryngoscopy, leading to a success rate of 100% without apparent complications. CONCLUSIONS: Hypothermia plasma cauterization with suspension laryngoscopy alongside 3D imaging is both minimally invasive and repeatable with neglectable complications, which has the potential to serve as the first-line treatment for CPSF in the future.

Endobronchial valve treatment of persistent alveolopleural fistulae in a patient with cystic fibrosis and empyema.

Persistent air leak (PAL) is a common problem after secondary pneumothorax due to cystic fibrosis (CF). These leaks, caused by either bronchopleural or alveolopleural fistula, are associated with higher morbidity and mortality [1]. Air leaks are traditionally treated with chronic chest tube drainage, chemical pleurodesis, or autologous blood patching in non-surgical candidates [1]. However, these strategies can increase infectious risk or pleural scarring, which are associated with poorer lung transplant surgical outcomes. Endobronchial valve (EBV) placement, while FDA-approved for use in both some surgical PALs and bronchoscopic volume reduction therapy, is one alternative option, but it could theoretically increase the risk of infection, especially in CF patients. Here, we report the case of a CF patient under evaluation for lung transplant who received EBVs for PAL after bilateral secondary spontaneous pneumothoraces.

Primary tracheocutaneous fistula closure with immediate transition to nocturnal noninvasive positive pressure ventilation in two children with Congenital Central Hypoventilation Syndrome.

Transitioning children with Congenital Central Hypoventilation Syndrome (CCHS) from nocturnal invasive ventilation via tracheostomy to noninvasive positive pressure ventilation (NIPPV) is challenging due to the leak caused by the tracheocutaneous fistula (TCF), resulting in insufficient ventilation. Decannulation and primary closure of the TCF with immediate transition to nocturnal NIPPV was performed in two children with CCHS at a tertiary care children's hospital. Neither child developed significant adverse effects such as pneumomediastinum or pneumothorax. This technique is a novel approach that may improve decannulation outcomes and aid transition to NIPPV in this patient population.

Reconstruction using facial artery system-based flaps. One vascular system for multiple purposes in head and neck reconstructive surgery. / Reconstrucción mediante colgajos basados en el sistema de la arteria facial. Un sistema vascular para múltiples usos en cirugía reconstructiva de cabeza y cuello.

INTRODUCTION: to review the modifications and advances in reconstructive surgery of the soft tissues of the oral cavity exclusively based on flaps that depend on the facial artery system. METHODS: review of the literature regarding oral cavity reconstructions based on main facial artery system flaps. DISCUSSION: The reconstruction of the soft tissues of the oral cavity, based on facial artery system flaps, offers satisfactory results and allows limited reconstructions avoiding the use of pedicled regional flaps or free flaps. CONCLUSIONS: Knowledge of reconstructive options using the facial artery system in oral cavity surgery allows expanding reconstructive options for head and neck surgeons, enabling safe, high quality and effective reconstructions, with limited resources consumption.
