The follow up of complex infants in an aerodigestive clinic.

The current available literature evaluating pediatric multidisciplinary aerodigestive programs for the management of aerodigestive disorders in infants was reviewed. Multidisciplinary aerodigestive programs have emerged to provide coordinated and comprehensive care for the growing population of children with aerodigestive conditions, including complex airway, pulmonary, gastrointestinal, and feeding disorders, which are prevalent among infants discharged from the neonatal intensive care unit (NICU). The team approach central to aerodigestive clinics offers a comprehensive diagnostic workup and unified management plan through consolidated interdisciplinary clinics, combined endoscopic procedures, and regular team discussions, leading to improved resource utilization and health care outcomes. We review common conditions presenting in the NICU that benefit from the aerodigestive model of care, including esophageal atresia, prematurity, bronchopulmonary dysplasia with or without tracheostomy or ventilator dependence, and dysphagia.

Incidence of synchronous malignancies found during triple endoscopy in head and neck cancer.

OBJECTIVES: To investigate the incidence of synchronous malignancies identified during triple endoscopy in patients with head and neck squamous cell carcinoma. METHODS: A retrospective chart review of patients from a tertiary academic medical center was performed. Patients with a primary head and neck squamous cell carcinoma who underwent triple endoscopy were included. Operative, radiographic, and pathology reports were reviewed to evaluate for the presence of synchronous malignancies in the aerodigestive tract diagnosed through endoscopy. Demographics, relevant medical history, including tobacco and alcohol use, and tumor characteristics were recorded. Univariate and multivariate regression analyses were conducted to assess for associations with synchronous malignancy on triple endoscopy. RESULTS: 215 patients were reviewed, 164 of which had a biopsy-positive head and neck squamous cell carcinoma and underwent triple endoscopy. Synchronous lesions were found in 8 patients (4.9%). Of the synchronous lesions, only two were identified on esophagoscopy and bronchoscopy; the remaining six were found on direct laryngoscopy. Clinical comorbidities including smoking and alcohol history, tumor p16 status, and tumor stage were not associated with presence of synchronous lesions. A positive synchronous lesion on positron emission tomography was significantly correlated with finding a synchronous lesion on triple endoscopy (p = 0.006). CONCLUSION: This study shows the incidence of synchronous lesions on triple endoscopy to be closer to 5%. While endoscopic examination can be useful in the anatomic characterization of head and neck malignancies, the low incidence of synchronous malignancies suggests that the need for triple endoscopy may be considered on a case-by-case basis.

Triple endoscopy and recurrent croup in children: A single aerodigestive center experience.

OBJECTIVE: To determine the utility of triple endoscopy (combined direct laryngoscopy, bronchoscopy (DLB), flexible bronchoscopy with bronchoalveolar lavage (FB + BAL), and esophagogastroduodenoscopy (EGD)) in the diagnosis and management of patients with recurrent croup (RC), and to identify predictors of endoscopic findings METHODS: A retrospective chart review was performed of pediatric patients (age <18 years) with RC evaluated by triple endoscopy at a tertiary care pediatric hospital from 2010 to 2021. Data including presenting symptoms, airway findings, BAL and EGD with biopsy findings were collected. RESULTS: 42 patients with RC underwent triple endoscopy were included. The mean age was 4.55±2.84 years old. The most common symptom was chronic cough among 19 (45%) patients, while 23 (55%) patients had gastrointestinal (GI) symptoms. Airway findings included tracheomalacia in 19, laryngeal cleft in 17, and subglottic stenosis in 11 patients. On EGD with biopsy, abnormal gross findings were present in 6 and abnormal microscopic findings in 18 patients, including 6 with histologic findings suggestive of gastroesophageal reflux and 5 with eosinophilic esophagitis. Seventeen (40%) patients had positive culture on BAL. No findings in patient histories significantly predicted presence of lower airway malacia, subglottic stenosis, or abnormal EGD findings. CONCLUSIONS: Children with recurrent croup presenting to aerodigestive centers may not have any pertinent presenting symptoms that correlate with significant findings on triple endoscopy. Further work is needed to determine which children with recurrent croup may benefit from aerodigestive evaluation. LEVEL OF EVIDENCE: Level 3.

Aerodigestive evaluation of pediatric patients with chronic aspiration.

OBJECTIVE: To evaluate the effectiveness of coordinated endoscopy with otolaryngology, pulmonology, and gastroenterology in diagnosing and managing chronic aspiration in pediatric patients. METHODS: We reviewed our REDCap Pediatric Aerodigestive Database for patients with chronic aspiration who underwent coordinated endoscopy between January 2013 and July 2023. Patient demographics, comorbidities, operative findings, interventions, and outcomes were reviewed. RESULTS: Forty-nine patients were identified with a diagnosis of aspiration. Their mean (SD) age was 28 (36) months (range 1.2-163 months) with more than half of the patients younger than 24 months. The most common findings noted on combined endoscopies were laryngeal cleft (n = 30), positive bacterial culture (n = 18), positive viral PCR (n = 17), and active reflux-induced esophagitis/gastritis (n = 9). Patients with a positive bacterial culture were associated with a history of recurrent pneumonia (p = 0.009). There were no other significant associations between endoscopy findings and patient demographics, co-morbidities, or symptoms. Twenty-five (51 %) had multiple abnormalities identified by at least 2 different specialists at the time of endoscopy and 6 patients (12 %) had abnormalities across all three specialists. CONCLUSION: Coordinated endoscopy should be considered in pediatric patients presenting with aspiration on MBS or non-specific symptoms suggestive for chronic aspiration for comprehensive diagnosis and management.

Paraneoplastic Manifestation of Primary Squamous Cell Cancer of the Thyroid Gland.

Paraneoplastic manifestation (PNM) of cancers is a non-metastatic, non-invasive systemic effect of malignancies due to chemokines and hormones produced by the primary neoplasm. Squamous cell cancers (SCCs) are known to present with PNM. Primary SCC of thyroid accounts for <1% of all thyroid malignancies and carries a very poor prognosis. We present a rare case of SCC arising from the thyroid gland who presented with fever, leukemoid reaction and hypercalcemia as part of PNM. A 67-year-old male patient presented with two months history of intermittent high-grade fever, weakness, loss of weight and appetite. Examination revealed a large (~10 cm) hard swelling over the right side of the neck. Investigations revealed neutrophilic leukocytosis, elevated C-reactive protein (CRP) and procalcitonin and hypercalcemia with a normal thyroid-stimulating hormone (TSH). The fever workup was negative for infection. Fine-needle aspiration cytology (FNAC) and core biopsy of the thyroid mass revealed malignant cells with squamous differentiation. An extensive search for possible other primary was ruled out by triple endoscopy. The combination of fever, neutrophilic leukocytosis, hypercalcemia and squamous malignancy was consistent with a diagnosis of PNM of SCC. A fluorodeoxyglucose-positron emission tomography (FDG-PET) CT scan showed a heterogeneously enhancing mass lesion in the right lobe of the thyroid with some retrosternal extension. He underwent total thyroidectomy with bilateral central compartment neck dissection. Final histopathology revealed moderately differentiated SCC of the thyroid. Concurrent chemoradiation was given. Despite continued chemotherapy, he succumbed to illness within six months of diagnosis. Primary SCC of thyroid (PSCCT) is a rare malignancy. It is a highly aggressive tumor having a poor prognosis with a median survival time of about 9-12 months and less clearly defined therapy due to its rarity. Paraneoplastic manifestation of PSCCT is known. As fever, leukemoid reaction and hypercalcemia can be a paraneoplastic manifestation, one should think of PSCCT.

Making the case for multidisciplinary pediatric aerodigestive programs.

Multidisciplinary pediatric aerodigestive centers have been proposed to address the needs of children with complex multi-system problems affecting the respiratory and upper gastrointestinal tracts. The setup of a multidisciplinary service allows for the complex coordination needed between different subspecialties. This allows for rapid communication and family-centered decision making and agreement on further diagnostic and/or therapeutic next steps such as offering triple endoscopy when indicated. Triple endoscopy entails performing rigid upper airway assessment, flexible bronchoscopy and upper gastrointestinal endoscopy and has been linked to reduced time to diagnosis/treatment, reduced costs and anesthesia exposure. This review summarizes the available literature on the structure and benefits of multidisciplinary pediatric aerodigestive services.

The diagnostic role of triple endoscopy in pediatric patients with chronic cough.

OBJECTIVE/HYPOTHESIS: Multi-disciplinary aero-digestive centers provide high quality health care through improved outcomes and treatment costs over separate sub specialty clinics. These outcomes are often the result of a common investigative tool known as triple endoscopy: a rigid bronchoscopy performed by an otolaryngologist, flexible bronchoscopy and lavage obtained by a pulmonologist, and an endoscopy with guided biopsies performed by a gastroenterologist. Combining such procedures into one 'triple endoscopy' allows for diagnoses which otherwise might have been missed with just one procedure. The goal of our study was to describe the efficacy of the triple endoscopy procedure in diagnosing recalcitrant aero-digestive conditions, specifically chronic cough. STUDY DESIGN: Retrospective chart review METHODS: Multiple charts from children who underwent the triple endoscopy for chronic cough were retrospectively reviewed from 2005 and 2017. Complete data from the triple procedure was gathered on 243 patients, including findings by sub specialty (otolaryngology, pulmonology, and gastroenterology). RESULTS: Of the 243 patients with complete data who underwent triple endoscopy, 203 (83.5%) children had at least one positive finding. Of these children, 101 (41.5%) had one specialty specific diagnosis, and 102 (42%) had multiple cross specialty diagnoses. When describing the diagnoses, 63 children had gastro esophageal reflux (GER), 14 had eosinophilic esophagitis (EoE), 118 had tracheomalacia, 54 had laryngeal clefts, and 102 children had positive bronchoalveolar lavages. Outcome data was available on 226 patients (93%), of these patients, 188 patients had a diagnosis from the triple scope. Of those patients with a diagnosis and outcome data, 144 (76.6%) children had an improved outcome as a result of a treatment plan targeting that diagnosis, while 16 of the 37 patients without a diagnosis improved. This difference was significant by chi square analysis (p<0.0001). CONCLUSION: The triple scope procedure is a useful investigative tool for patients with recalcitrant aero-digestive complaints like chronic cough. In particular, triple scope can yield more than one specialty specific diagnosis, normally missed by one procedure. The triple scope also leads to improved parental satisfaction by improved cost and healthcare outcomes.

Rigid Triple Endoscopy Improves Clinical Staging of Primary Head and Neck Cancer.

BACKGROUND: Correct pre-therapeutic staging of the first primary carcinoma (FPC) and detection of simultaneous second primary carcinomas (SSPCs) decisively influence therapy and prognosis of head and neck squamous cell carcinomas (HNSCC). The aim of this study was to determine the benefit of pre-therapeutic triple endoscopy for detection of SSPC and pre-therapeutic T category. METHODS: A cohort of 234 HNSCC patients with completed triple endoscopy was reviewed, focusing on pre-therapeutic T category and SSPC. Risk stratification for different subsites was evaluated. RESULTS: The risk for SSPC was 5.56%. FPC of the oral cavity and oropharynx had the highest prevalence of SSPC (46.15%, 38.46%); most SSPCs were found in the hypopharynx. No SSPCs were found in the oral cavity, nasopharynx and oesophagus. Significant results in correct pre-therapeutic T staging have been achieved for the larynx (p = 0.021) and the oropharynx (p = 0.001). CONCLUSIONS: Triple endoscopies seem to be inadequate for SSPC detection in HNSCC patients. Endoscopies of the trachea and oesophagus should be reconsidered. Alternatively, risk-directed endoscopies of the hypopharynx might be performed in patients with oral cancer. For evaluation of resectability, conducting triple endoscopy could be reduced to a single endoscopy because the complication rate is low and pre-therapeutic T staging can be improved.
