Effectiveness and safety of a ventricular septal occluder device for the treatment of Gastro-tracheal fistula.

BACKGROUND: Gastro-tracheal fistula (GTF) is one of the most serious complications after esophagogastrostomy and radiotherapy, with very high disability and mortality rates. To evaluate the effectiveness and safety of ventricular septal occluder devices (VSOD) for the treatment of Gastro-tracheal fistula (GTF). METHODS: From January 2020 to May 2022, 14 patients with GTF underwent VSOD under real-time fluoroscopy. The technical success, complications, quality of life (QoL), Eastern Cooperative Oncology Group (ECOG) score, Karnofsky score, and median overall survival (mOS) were recorded and analyzed. RESULTS: Technical success, and major complication rates were 71.4%, and 14.3%, respectively. Both the ECOG and the Karnofsky score showed significant improvement at the 2-month evaluation compared with the pretreatment value (p<0.05). For QoL, general health, physical function, vitality, role physical, and social function all improved at the 2-month evaluation (p<0.05), but bodily pain, role emotion, and mental health showed no significant difference (P>0.05). During the mean follow-up of 9.6 months, eight patients were alive, and the mOS was 11.4 months (95% CI, 8.5-14.3). CONCLUSIONS: VSOD is a simple and safe technique for GTF treatment, but long-term observation is needed at multiple centers to confirm our findings.

A Systematic Review of Mortality Associations in Patients who Develop Tracheoinnominate Artery Fistula Following Tracheostomy.

OBJECTIVE: Tracheoinnominate artery fistulas (TIFs) are a rare but deadly complication of tracheostomy. Tracheoinnominate artery fistula cases in the literature were summarized in order to understand mortality associations. METHODS: MEDLINE was searched for studies reporting individual characteristics of patients with TIFs after tracheostomy, excluding cases without tracheostomy or with additional procedures at the tracheostomy site. This study followed PRISMA guidelines. RESULTS: 121 TIF patients from 18 case series and 46 case reports were included. The median age was 40 years, and 52.9% were male. The overall mortality rate was 64.5%. There were differences in mortality between cases that presented initially with vs without sentinel bleeding (odds ratio [OR] .34; CI [confidence interval] .16-.73; P = .006). The mortality rate also differed in whether or not the tracheostomy cuff was over-inflated for temporary hemostasis during resuscitation (OR 3.57 (CI 1.57-8.09); P = .002). Treatment compared to no treatment had lower mortality rates (OR .11 (CI 0.04-.32); P < .001); no differences were found if treatment was endovascular vs open surgical. CONCLUSIONS: Mortality is a major concern after detection of a TIF and resuscitation paired with endovascular or open surgical intervention is imperative. Rapidly investigating sentinel bleeds and intervening upon hemorrhage with temporary cuff over inflation may lead to improved outcomes.

Pediatric Tracheotomy Stomal Maturation and Tracheocutaneous Fistulas.

OBJECTIVE: The purpose of this study is to determine whether tracheostomy stomal maturation affects the risk of tracheocutaneous fistula (TCF) in children. METHODS: A retrospective chart review was conducted for all children who both underwent a tracheostomy and were decannulated between 2012 and 2021 at a tertiary children's hospital. Charts were analyzed for demographics, surgical technique, and development of a TCF. TCF was defined as a persistent fistula following 3 months after decannulation. RESULTS: 179 children met inclusion criteria. The median (interquartile range) age at tracheostomy was 1.5 (82.4) months, average (standard deviation [SD]) duration of tracheotomy was 20.0 (20.6) months, and length of follow-up after decannulation (range; SD) was 39.3 (4.4-110.0; 26.7) months. 107 patients (60.0%) underwent stomal maturation and 98 patients developed a TCF (54.7%). Younger age at tracheostomy placement was significantly associated with increased risk of TCF, mean (SD) age 28.4 (51.4) version 80.1 (77.5) months (p < 0.001). Increased duration of tracheostomy was significantly associated with increased risk of TCF, 27.5 (18.4) version 11.0 (18.2) months (p < 0.001). Stomal maturation was not significantly associated with the risk of TCF, including on multivariable analysis adjusting for age at tracheostomy and duration of tracheostomy (p = 0.089). CONCLUSION: Tracheostomy stomal maturation did not affect the risk of TCF in children, even after adjusting for age and duration of tracheostomy.

Bronchoscopic Intervention for Tracheobronchopathia Osteochondroplastica: A Report of Two Cases.

Tracheobronchopathia osteochondroplastica (TO) is an uncommon non-malignant tracheal ailment characterized by the existence of numerous bone and/or cartilage nodules in the submucosa of the trachea and bronchi. At present, there is a lack of standardized treatment recommendations for TO. This article presents two instances of severe tracheal stenosis caused by TO, which were effectively managed through the implementation of bronchoscopic stent placement and rigid bronchoscopy curettage, respectively. Both cases exhibited favorable outcomes, providing novel insights and references for the treatment of TO. Laryngoscope, 134:3093-3095, 2024.

Rare and unexpected ventilation difficulties due to tracheal diverticulum: A case report.

RATIONALE: Tracheal diverticulum is a rare airway-related particular occurrence, and the forcible tube insertion may cause tracheal ruptures during tracheotomy. Therefore, fiberoptic bronchoscopy (FOB) should be used routinely on all patients undergoing tracheal intubation or tracheotomy. PATIENT CONCERNS: A 60-year-old male with laryngeal neoplasms was scheduled for partial laryngectomy using a suspension laryngoscope in July 2020. All operations were performed under general anesthesia through orotracheal intubation. Orotracheal intubation was a noninvasive procedure that could effectively control breathing. At the end of the surgery, the percutaneous tracheostomy was performed to maintain airway patency, facilitate spontaneous respiration, and remove the secretions. DIAGNOSES: At this moment, the tracheal diverticulum, located at the right posterolateral region of the trachea, became an unexpected airway-related particular occurrence, which led to tracheal tube placement difficulty, mechanical ventilation difficulty, and high airway pressure. INTERVENTIONS: Subsequently, the tracheal tube was repositioned, with placement again confirmed by the FOB. LESSONS SUBSECTIONS: Tracheal diverticulum is an infrequent cause of tube inserting difficulty for the tracheotomy, and FOB is the first option for patients with catheter placement difficulty and mechanical ventilation difficulty.

Posterior Tracheal Diverticulum in a Patient Undergoing Tonsillectomy.

This case report describes a male patient in his 20s who presented with bilateral palatine tonsil enlargement and history of infections 4 to 5 times per year and was subsequently found to have tracheal diverticulum.

Closure of Tracheocutaneous Fistulae in Patients With Challenged Wound Healing.

OBJECTIVE: To describe and evaluate the surgical outcomes of multilayered closure of persistent tracheocutaneous fistulae (TCF) in patients with challenged wound healing. METHODS: A retrospective chart review of all patients who underwent closure of TCF by the senior author between October 2011 and December 2021 was performed. Age, body mass index (BMI), time between decannulation and TCF repair, medical comorbidities, procedure duration, length of hospitalization, and postoperative complications were recorded. The primary outcomes were closure of the fistula, postoperative subcutaneous emphysema, pneumomediastinum, pneumothorax, wound infection, or breakdown. Outcomes of patients with and without challenged wound healing were compared. RESULTS: Thirty-five patients who underwent TCF repair during the study period were identified. The mean age and BMI were 62.9 years and 28.43 respectively. Twenty-six (74%) patients met criteria for challenged wound healing at the time of the TCF repair. There was 1 (3.84%) minor complication in the challenged wound healing group and none (0%) in the control group (P = 1.00). No patients experienced wound breakdown or air leak noted on exam or chest radiography. CONCLUSION: Multilayered closure of persistent tracheocutaneous fistulae is a simple technique which is safe and effective even in patients with challenged wound healing.

The Predictors of Persistent Posttracheostomy Tracheocutaneous Fistula and Successful Surgical Closure.

OBJECTIVE: Persistent tracheocutaneous fistula is a well-described complication of prolonged tracheostomy, with a prevalence of about 70% when decannulation is performed after more than 16 weeks. Predictors of its occurrence and outcome of treatment in adults remain unclear. The aim of the study was to describe our experience with the treatment of persistent posttracheostomy tracheocutaneous fistula in adults and to investigate factors associated with its formation and with the success of surgical closure. STUDY DESIGN: Retrospective cohort. SETTING: Tertiary medical center. METHODS: Patients who underwent open-approach tracheostomy between 2000 and 2020 were identified by database review. Data on background, need for surgical closure, and the surgical outcome was collected from the medical files and analyzed statistically between groups. RESULTS: Of 516 patients identified, 127 with sufficient long-term follow-up data were included in the study. Compared to patients whose fistula closed spontaneously (n = 85), patients who required surgical closure (n = 42) had significantly higher rates of smoking, laryngeal or thyroid malignancy, and airway obstruction as the indication for tracheostomy, on both univariate and multivariate analysis. In a comparison of patients with successful (n = 29) or failed (n = 11) surgical closure, factors significantly associated with failure were prior radiotherapy and lower preoperative albumin level, on univariate analysis. CONCLUSION: Smoking, thyroid or laryngeal malignancy, and airway obstruction indication are risk factors for persistent posttracheostomy tracheocutaneous fistula. Patients should be closely followed after tracheostomy and referred for surgery if the fistula fails to close. Before surgery, careful evaluation of the patient's nutritional status and consideration of prior radiation treatment is mandatory.

Surgical treatment of tracheocutaneous fistula and tracheostomy scars using a hinged flap and local myocutaneous flap.

Tracheocutaneous fistula and tracheostomy scar are complications associated with the prolonged use of tracheostomy tubes. They have functional and cosmetic problems owing to tracheal tugging during swallowing and easily visible scars. Although many procedures exist to correct this issue, there is no consensus on the optimal surgical technique. Therefore, an ideal surgical procedure was devised. The study was performed on 12 patients between September 2016 and May 2021. All patients had persistent tracheocutaneous fistulas or hypertrophic scars on the neck after tracheostomy. All procedures were performed using a hinged flap and two myocutaneous local flaps. All patients had no complications, and their aesthetics were excellent in postoperative photographs. The scar was better on the straight scar when the flap's skin is denuded than on the VY advancement flap. It should be noted, however, that this procedure can cause the flap to become congested in a short period after head and neck surgery. This procedure is safe, reliable and simple for surgical closure. This was found to produce excellent cosmetic results with no major complications.

Human Tracheal Transplantation.

Long-segment tracheal airway defects may be congenital or result from burns, trauma, iatrogenic intubation damage, or tumor invasion. Although airway defects <6 cm in length may be reconstructed using existing end-to-end reconstructive techniques, defects >6 cm continue to challenge surgeons worldwide. The reconstruction of long-segment tracheal defects has long been a reconstructive dilemma, and these defects are associated with significant morbidity and mortality. Many of these defects are not compatible with life or require a permanent extended-length tracheostomy that is fraught with complications including mucus plugging and tracheoesophageal fistula. Extensive circumferential tracheal defects require a reconstructive technique that provides a rigid structure able to withstand the inspiratory pressures, a structure that will biologically integrate, and contain functional ciliated epithelium to allow for normal mucociliary clearance. Tracheal transplantation has been considered the reconstructive "Holy Grail;" however, there has been a long-held scientific dogma that revascularization of the trachea was not possible. This dogma stifled research to achieve single-staged vascularized tracheal transplantation and prompted the introduction of many creative and inventive alternatives. Throughout history, alloplastic material, nonvascularized allografts, and homografts have been used to address this dilemma. However, these techniques have largely been unsuccessful. The recent introduction of a technique for single-staged vascularized tracheal transplantation may offer a solution to this dilemma and potentially a solution to management of the fatal tracheoesophageal fistula.

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.

Incidence of Persistent Tracheocutaneous Fistula After Pediatric Tracheostomy Decannulation.

OBJECTIVES: To determine the incidence of tracheocutaneous fistula (TCF) and identify characteristics associated with persistence. STUDY DESIGN: Prospective cohort. METHODS: All successfully decannulated children (<18 years) between 2014 and 2020 at a tertiary children's hospital were included. Revision tracheostomies, concomitant major neck surgery, or single-stage laryngotracheal reconstructions were excluded. A persistent TCF was defined as a patent fistula at 6 weeks after decannulation. RESULTS: A total of 77 children met inclusion criteria with a persistent TCF incidence of 65% (50/77). Children with a persistent TCF were younger at placement (1.4 years (SD: 3.3) vs. 8.5 years (SD: 6.5), p < 0.001) and tracheostomy-dependent longer (2.8 years (SD: 1.3) vs. 0.9 years (SD: 0.7), p < 0.001). On univariate analysis, placement under 12 months of age (86% vs. 26% p < 0.001), duration of tracheostomy more than 2 years (76% vs. 11% p < 0.001), short gestation (64% vs. 26%, p = 0.002), congenital malformations (64% vs. 33%, p = 0.02), newborn complications (58% vs. 26%, p = 0.009), maternal complications (40% vs. 11%, p = 0.009) and chronic respiratory failure (72% vs. 41%, p = 0.01) were associated with persistent TCF. Logistic regression analysis associated duration of tracheostomy (OR: 0.14, 95% CI: 0.05-0.35, p < 0.001) and congenital malformations (OR: 0.25, 95% CI: 0.06-0.99, p = 0.049) with failure to spontaneously close. CONCLUSIONS: Two-thirds of children will develop a persistent TCF after tracheostomy decannulation. Persistent TCF is correlated with a longer duration of tracheostomy and congenital malformations. Anticipation of this event in higher-risk children is necessary when caring for pediatric tracheostomy patients. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:417-422, 2023.

Successful management of a tracheomalacia patient with active endotracheal bleeding due to intraoperative innominate artery injury: A case report.

RATIONALE: Intraoperative innominate artery injury is life-threatening in tracheomalacia patients with prolonged tracheostomy. Anesthetic management is challenging in cases with massive hemorrhage into the endotracheal tube. We report a case in which we successfully managed a tracheomalacia patient with acute endotracheal bleeding due to innominate artery injury. PATIENT CONCERNS: A 24-year-old patient with tracheomalacia was scheduled to undergo exploratory thoracotomy for the treatment of intermittent bleeding at the tracheostomy site. During exploration, sudden active bleeding due to innominate artery injury was observed in the endotracheal lumen. DIAGNOSES: The patient was diagnosed with tracheomalacia. INTERVENTIONS: We immediately used the bronchoscope to place the tip of the endotracheal tube at the bleeding site and hyperinflated the cuff. OUTCOMES: The ballooned cuff compressed the active bleeding site, so no additional bleeding was detected by bronchoscopy, and no additional massive bleeding was observed in the operative field. LESSONS: Immediate and appropriate overinflation of the endotracheal tube cuff by an anesthesiologist may provide improved surgical field visibility and time for critical surgical procedures in cases of massive hemorrhaging.

Tracheobronchopathia osteochondroplastica: A rare case of misdiagnosis and difficult intubation.

Tracheobronchopathia osteochondro-plastica (TPO) is a rare disorder of yet unknown etiology. The common clinical features include cough with expectoration, breathing difficulty, hemoptysis, and recurrent airway infections, which can lead to a misdiagnosis as another chronic respiratory illness in a large number of cases due to the rare nature of TPO. Here we present a 25-year-old lady who was misdiagnosed as bronchial asthma for many years, and was found to have TPO after difficulty in intubation for administering general anesthesia prior to a surgical procedure.

Too big to fail?-An aggressive strategy for a dire problem.

Tracheo-innominate fistula (TIF) is a reported complication of tracheostomy that typically presents with a herald bleed. The phenomenon of an aortotracheal fistula has similar pathology and presentation to TIF, but no standard surgical repair. In the manuscript by Musgrove et al. in the Journal of Cardiac Surgery, the authors propose a surgical treatment that is reproducible for the correct anatomic configuration-an ascending and aortic arch replacement, pericardial patch of the tracheal defect, and omental flap coverage. While this intervention is a large undertaking for a small defect, it is a safe and durable repair.

Therapeutic outcomes of laryngeal closure and laryngostomy in children with recurrent pneumonia.

PURPOSE: Children with medical complexity frequently experience difficulty breathing and swallowing and occasionally develop aspiration pneumonia. Long-term intubation may cause fatal trachea-innominate artery fistula (TIF). In the present study, we retrospectively evaluated the efficacy of laryngeal closure and laryngostomy in children with medical complexity. MATERIALS AND METHODS: Laryngeal closure and laryngostomy were performed in eight children with severe neuromuscular disorders who were incapable of oral ingestion and verbal communication. The laryngostoma was placed at a higher position compared to that in conventional tracheostomies for easier management of the airway and to prevent TIF. RESULTS: Aspiration was successfully prevented postoperatively in all cases. Laryngocutaneous fistula formation was not observed. Two patients successfully achieved oral ingestion capability and tracheal cannulas were removed in two patients. Among the six patients who needed a mechanical ventilator before surgery, two patients were weaned from mechanical ventilation. Five patients were successfully discharged from the hospital. Although two patients died because of their primary condition, pneumonia exacerbation was not observed in any of the patients. CONCLUSION: Compared to the conventional tracheostomy, our procedure improved airway management and function in children with medical complexity and reduced the risk of TIF.

Tracheal Diverticulum as a Cause of Recurrent Infection in Post-Lung Transplant Patients: A Report of 2 Cases.

BACKGROUND: Tracheal diverticulum (TD) is a rare entity in clinical practice, accidentally found by imaging methods. It is a potential factor for the development of chronic respiratory infections, contributing to the progression of preexisting lung diseases and putting the success of lung transplantation at risk. OBJECTIVES: This paper reports 2 cases of TD with atypical clinical presentation in post-lung transplant patients with recurrent infections and aims to present the importance of this differential diagnosis. DISCUSSION: Case 1: A 30-year-old man with terminal lung disease underwent bilateral lung transplantation with a satisfactory postoperative period. He presented with TD as a focus of recurrent infection associated with persistent hemoptysis. Indicated for surgical resection (cervicotomy with resection of tracheal diverticulum), without complications. He evolved uneventfully in the postoperative period and was clinically stable at follow-up. Case 2: A 57-year-old woman with hypersensitivity pneumonia associated with secondary pulmonary arterial hypertension and bronchiectasis underwent bilateral lung transplantation without complications. She presented with TD as a focus of infection associated with esophageal symptoms. Indicated for the surgical approach (cervicotomy with resection of tracheal diverticulum), she was asymptomatic at follow-up. CONCLUSION: Conservative treatment is recommended in elderly and asymptomatic patients. Surgical resection is based on the recurrence of symptoms and failure of clinical therapy and is the preferred approach for reported cases.
