Algorithmic Approach to Reconstruction of Esophageal/Hypopharyngeal Injuries After Anterior Cervical Spinal Fusion.

BACKGROUND: Anterior cervical disk fusion (ACDF) is a common surgical approach for the treatment of cervical spine pathology. Esophageal perforations, though uncommon, are a devastating complication of this surgery. The objective of this paper is to assess the success of different treatment approaches for the management of esophageal/pharyngeal injury after ACDF. METHODS: Given the absence of prospective trials, the review includes institutional case reports and case series from 1985-2020 in the English language literature. Only cases of esophageal/pharyngeal injury in the setting of anterior cervical hardware were considered for study inclusion. For purposes of this study, treatment success is defined as resumption of oral intake. RESULTS: The database review identified 76 distinct series that meet criteria for study inclusion, with 173 patients available for analysis. A heterogeneous array of treatments was used for the management of pharyngoesophageal injuries after ACDF ranging from observation to complex free tissue reconstruction, with varying degrees of treatment success reported. We identified a number of factors, specifically duration of injury from initial ACDF procedure, which may impact the complexity of treatment required to maximize likelihood of treatment success. CONCLUSIONS: Pharyngoesophageal injuries, albeit rare, are a serious and often complex complication after ACDF procedures. We propose a detailed algorithmic approach to guide decision making if faced with this clinical challenge. The huge variability in how these patients are treated emphasizes the potential utility of future multiinstitutional studies.

Extraglottic Airway Device Misplacement: A Novel Classification System and Findings in Postmortem Computed Tomography.

STUDY OBJECTIVE: Extraglottic airway devices are frequently used during cardiac arrest resuscitations and for failed intubation attempts. Recent literature suggests that many extraglottic airway devices are misplaced. The aim of this study is to create a classification system for extraglottic airway device misplacement and describe its frequency in a cohort of decedents who died with an extraglottic airway device in situ. METHODS: We assembled a cohort of all decedents who died with an extraglottic airway device in situ and underwent postmortem computed tomographic (CT) imaging at the state medical examiner's office during a 6-year period, using retrospective data. An expert panel developed a novel extraglottic airway device misplacement classification system. We then applied the schema in reviewing postmortem CT for extraglottic airway device position and potential complications. RESULTS: We identified 341 eligible decedents. The median age was 47.0 years (interquartile range 32 to 59 years). Out-of-hospital personnel placed extraglottic airway devices in 265 patients (77.7%) who subsequently died out of hospital; the remainder died inhospital. The classification system consisted of 6 components: depth, size, rotation, device kinking, mechanical blockage of ventilation opening, and injury. Under the system, extraglottic airway devices were found to be misplaced in 49 cases (14.4%), including 5 (1.5%) that resulted in severe injuries. CONCLUSION: We created a novel extraglottic airway device misplacement classification system. Misplacement occurred in greater than 14% of cases. Severe traumatic complications occurred rarely. Quality improvement activities should include review of extraglottic airway device placement when CT images are available and use the classification system to describe misplacements.

Tubo gástrico isoperistáltico, alternativa quirúrgica en quemadura faringoesofágica. Caso clínico / Isoperistaltic gastric tube: a surgical alternative in a pharyngoesophageal burn - a clinical case

INTRODUCCIÓN: Las quemaduras por ingesta de cáusticos en la población pediátrica continúan siendo causa de lesiones esofágicas complejas. Sin embargo, las posibilidades terapéuticas en casos severos son limitadas. Se propone un abordaje quirúrgico en el cual se obtiene mayor longitud del neoesófago, esófago isoperistáltico y mejor vascularización con el subsecuente menor riesgo de complicaciones (necrosis, estenosis, perforación). CASO CLÍNICO: Paciente de 16 meses de edad, quien presenta ingesta accidental de sosa cáustica que ocasiona quemadura grado IIIb que compromete desde la faringe hasta el estómago. Se realizó reemplazo esofágico con tubo gástrico isoperistáltico, con lo cual se obtuvo un neoesófago de longitud apropiada, vascularización óptima para el injerto y peristaltismo fisiológico. COMENTARIOS: El abordaje quirúrgico propuesto permite obtener un esófago con irrigación proveniente de la arteria gastroepiploica derecha, preservando irrigación de la curvatura mayor, una longitud mayor y por el posicionamiento anatómico del esófago con un peristaltismo fisiológico

INTRODUCTION: Caustic burns still cause complex esophageal lesions in the pediatric population. However, therapeutic possibilities in severe cases are limited. A surgical approach allowing for a longer neoesophagus, an isoperistaltic esophagus, and a better vascularization, with a lower risk of complications such as necrosis, stenosis, or perforation, is proposed. CLINICAL CASE: 16-month-old patient who accidentally ingested caustic soda. This caused a IIIb degree burn compromising the pharynx down to the stomach. Esophageal replacement with an isoperistaltic gastric tube was carried out, which allowed for a neoesophagus of appropriate length, an optimal vascularization for the graft, and physiological peristalsis. COMMENTS: The surgical approach proposed allows the esophagus to be irrigated from the right gastro-omental artery, thus preserving irrigation of the greater curvature. It also allows for a longer esophagus, and thanks to anatomical positioning, for physiological peristalsis

Transoral Removal of an Extruded Odontoid Screw Causing Dysphagia and Dysphonia.

A 77-year-old male underwent open reduction and internal fixation with placement of odontoid screws after sustaining C1 arch and odontoid fractures in a fall 14 months prior to presentation to the laryngology clinic for combined surgery with orthopedics. Serial imaging after the initial surgery demonstrated loosening of a screw and its entry into the pharyngeal lumen. The patient reported odynophagia, dysphagia, and dysphonia. He reported taking small bites and using liquid assist, vocal fatigue, and difficulty with pitch control. A surgical screw entering the pharynx just inferior to the level of the tip of the epiglottis was seen on flexible laryngoscopy. On phonation, the screw made intermittent contact with the right arytenoid resulting in restriction of full abduction of the right vocal fold. On flexible endoscopic evaluation of swallowing, there was pharyngeal and vallecular residue, and residue around the screw itself. The patient was taken to the operating room with orthopedic surgery, the screw was visualized with a combination of mouth gag and endoscopes. It was gently rocked with an orthopedic screw grabber and tapped toward the caudal pharynx. After successful removal, the mucosal defect was sutured. The patient reported improvement in swallowing postoperatively. Dysphagia is a described sequela of cervical spine surgery. We describe the presentation and treatment of a patient with a history of cervical spine surgery and subsequent exposure of an orthopedic screw in the pharynx. Laryngoscope, 131:1078-1080, 2021.

Management of foreign bodies in the ear, nose and throat in children: a review of 829 cases from Northern Anatolia.

<b>Objective:</b> The aim of this study was to evaluate cases of of ear, nose and pharyngeal (ENT) foreign body (FB) in pediatric patients referred to the pediatric emergency department of the Department of Otorhinolaryngology in Tokat State Hospital (Turkey). <br><b>Methods:</b> The paper comprises a retrospective study of all ENT foreign bodies presented to the pediatric emergency Department of Otorhinolaryngology in Tokat State Hospital (Turkey) between January 1, 2012 and December 31, 2018. Subject to evaluation were also demographic and clinical characteristics of the patients, types and anatomic locations of FBs, locations of FB by age groups, the method used to remove FBs and the distribution of FB cases by months. <br><b>Results:</b> A total of 829 FB cases were evaluated in this study. The mean age of patients was 47.8 ± 31.4 months. Of all patients, 404 (48.5%) were male, and 425 (51.2%) were female. The nose (58.7%) and the ear (20.2%) were the most common anatomical locations followed by mouth/pharynx/tonsil (12.3%), esophagus (6.2%) and the laryngotracheobronchial tree (2.4%). The most common FBs in different locations were beads in the nose (30.8%), beads in the ear (32.1%), fishbones in the mouth/pharynx/tonsil (56.8%), nuts and peanuts in laryngotracheobronchial tree (70%) and a coin/disc battery in the esophagus (80.7%). <br><b>Conclusion:</b> FB in ENT is among the emergency conditions that require different diagnostic and treatment approaches based on anatomic localizations. Proper vision, adequate equipment and immobilization are important in the removal of ENT foreign bodies in children.

Determining airway complications during anaesthesia induction: a prospective, observational, cross-sectional clinical study.

BACKGROUND: Although postoperative early airway complications are rarely observed, when they do develop, fatal results such as brain damage and cardiac arrest may occur. The Royal College of Anaesthetists and Difficult Airway Society investigated airway complications developing during anaesthesia over a period of 12 months within the context of the Fourth National Audit Project (NAP4) study. Inspired by that multicentre research project, this study aims to identify early airway complications that can develop in relation to anaesthesia induction in our hospital. METHODS: After our proposed study received approval from the Ethical Council, adult patients undergoing general anaesthesia at our operating theatres within the period of January-July 2018 were included in it. Demographic data, ventilation, American Society of Anesthesiologists (ASA) grade, Cormack-Lehane scores, tools that are used in airway management, and complications were recorded. RESULTS: Out of 909 patients in total, 752 were intubated; a laryngeal mask was placed on 157 of these patients. The complication rate was 5%, and the 3 most frequently observed complications were desaturation, bronchospasm and pharyngeal injuries. In the group having complications, the body mass index value, Cormack-Lehane, Mallampati, and ventilation scores were significantly higher than those with no complications. CONCLUSIONS: During routine general anaesthesia induction at our clinic, major or minor airway complications have developed with a frequency of 5%, and it was determined that desaturation was the most frequent reversible cause.

Pharyngeal perforation following laryngoscopy in a patient with dysphagia secondary to diffuse idiopathic skeletal hyperostosis: A case report.

RATIONALE: Dysphagia is a common presenting symptom in elderly people. Nevertheless, dysphagia resulting from diffuse idiopathic skeletal hyperostosis (DISH) of patients' cervical spine may be due to several factors. Despite computed tomography scan showing the size and shape of osteophytes, endoscopy may be necessary to exclude other intrinsic causes of dysphagia. Due to the anatomic variation of the pharynx secondary to DISH, patients undergoing endoscopy are at risk of perforation. Once perforation occurs, inappropriate treatments may finally lead to an irretrievable outcome. PATIENT CONCERNS: A 58-year-old male patient with a 20-day history of dysphagia initially visited an ear-nose-throat (ENT) doctor. He had no neck pain and no other history of cervical disease. DIAGNOSIS: This patient with dysphagia due to DISH of the cervical spine underwent laryngoscopy to exclude other causes. Pharyngeal perforation resulted as a complication of the procedure. INTERVENTIONS: The patient underwent laryngoscopy and biopsy by an ENT doctor to exclude intrinsic causes. After the procedure, a perforation was formed on the posterior wall of the pharynx. Conservative management, that is, 1 week of nothing per oral, and 1 month of antibiotics, was adopted. On the 30th day after the examination, the patient was voluntarily discharged from the hospital and recommended to take antibiotics orally. OUTCOMES: On the 56th day, the patient experienced fever and neck pain. Magnetic resonance imaging showed that the cervical vertebral bodies and spinal cord were infected. On the midday of the 60th day, the patient had a failed resuscitation and died. LESSONS: DISH involving the cervical spine is a complicated cause of dysphagia. Due to the anatomic variation of the pharynx secondary to DISH, patients undergoing endoscopy are at risk of perforation. If other intrinsic causes of dysphagia have to be excluded with the aid of endoscopy, plain films and computed tomography images should be read carefully first. To minimize the risk of perforation, it is necessary to perform endoscopy extremely carefully, especially biopsy. Once perforation occurs, operative treatment may be more appropriate and effective.

Transoral Endoscopic Approach to Repair Early Pharyngeal Perforations After Anterior Cervical Spine Surgery without Failure of Instrumentation: Our Experience and Review of Literature.

BACKGROUND: Pharyngoesophageal injury during anterior cervical spine surgery is a rare and potentially life-threatening complication; generally it is the result of intraoperative manipulation or hardware erosion and sometimes may be due to weakness of the pharyngoesophageal wall from pre-existing pathologic conditions, such as diabetes, gastritis, or obesity. CASE DESCRIPTION: We describe the management strategies in patients with an early postoperative hypopharyngeal perforation that occurred after anterior cervical spine surgery without failure of instrumentation, and we present a case treated endoscopically at our institution. CONCLUSIONS: Appropriate treatment for pharyngoesophageal perforations is controversial and not investigated in detail. There is a lack of prospective studies comparing initial conservative versus surgical approaches to treatment. In addition, endoscopic management is growing as a therapeutic option, but no consensus concerning the indications for an endoscopic approach in the treatment of pharyngoesophageal injury in anterior cervical spine surgery is currently reached. A common theme proposed in the literature is that early recognition and aggressive investigation and treatment are essential to ensure a good outcome. A customized interdisciplinary surgical approach is essential for successful treatment. Use of the transoral endoscopic approach is a useful noninvasive method to treat this rare but potentially devastating complication.

Pharyngo-Esophageal Perforations After Anterior Cervical Spine Surgery: Management and Outcomes.

OBJECTIVE: To report about the diagnosis, surgical treatment, and postoperative management of pharyngo-esophageal perforations (PEPs) after anterior cervical spine (ACS) surgery in 17 patients. METHODS: A retrospective multicenter case series of patients surgically treated for PEP after ACS surgery was performed. Data regarding cervical spine pathology and surgery, comorbidities, diagnosis and surgical management of PEP, airway management, antibiotic therapy, postoperative course, and feeding route after repair surgery at discharge and last follow-up were collected. RESULTS: Seventeen patients were included in the study, for a total of 22 surgical procedures for PEP repair. Seven PEPs (41%) had early onset, whereas 10 (59%) were delayed. All patients underwent PEP surgical repair through an anterior prevascular retrovisceral cervicotomic approach, consisting of multiple layer sutures of the perforation, with flap interposition. Despite the challenging management of these patients, 16 of 17 patients from our series restored oral feeding. CONCLUSIONS: PEPs are among the most appalling complications of cervical spine surgery. Because of their rarity and heterogeneous presentation, a standardized management is difficult to define. From our experience with the largest case series in the literature, a multidisciplinary approach is advisable to deal with these patients.

Common Pulmonary Conditions in Sport.

Respiratory symptoms and infections are common among athletes. Viral upper respiratory infection symptoms may precede dyspneic symptoms seen in asthmatics or worsen symptoms of exercise-induced bronchoconstriction Knowing how to instruct an athlete on use of inhalers and having an asthma action plan are critical in management of these athletes. Other life-threatening conditions that may be seen are pneumothorax and laryngeal/pharyngeal perforation. Prompt recognition and treatment are crucial if an athlete is suspected to have pulmonary compromise. Laryngeal/pharyngeal perforations are a rare cause of issues within the training room but require a high degree of suspicion to be diagnosed and managed properly.

A randomised controlled trial of the effect of laryngeal mask airway manometry on postoperative sore throat in spontaneously breathing adult patients presenting for surgery at a university teaching hospital.

BACKGROUND: Laryngeal mask airways (LMAs) are widely used in anaesthesia and are considered to be generally safe. Postoperative sore throat (POST) is a frequent complication following LMA use and can be very distressing to patients. The use of an LMA cuff pressure of between 30 and 32cm of H2O in alleviating post-operative sore throat has not been investigated. OBJECTIVE: To compare the occurrence of POST between the intervention group in which LMA cuff pressures were adjusted to 30-32cm of H2O and the control group in which only monitoring of LMA cuff pressures was done, to compare the severity of POST between the two study groups and to compare the LMA cuff pressures between the two study groups. METHODS: Eighty consenting adult patients scheduled to receive general anaesthesia with use of an LMA were randomized into two groups of 40 patients each. Intervention group: LMA airway cuff pressures were adjusted to 30 to 32cm of H2O. Control group: Only had LMA cuff pressures monitored throughout the surgery. All patients were interviewed postoperatively at two, six and twelve hours. Data of their baseline characteristics, occurrence and severity of POST was collected. If POST was present; a Numerical Rating Scale (NRS) was used to assess the severity. Cuff pressures between the two study groups were also determined. RESULTS: The baseline demographic characteristics of the participants were similar. The use of manometry to limit LMA AMBU® AuraOnce™ intracuff pressure to 30-32cm H2O reduced POST in surgical patient's by 62% at 2 hours and 6 hours (Risk Ratio 0.38 95%CI 0.21-0.69)in the intervention group. The median POST pain score in the intervention group was significantly lower than the control group with scores of 0 at 2, 6 and 12 hours post operatively. Routine practice of LMA cuff inflation by anesthesiologists is variable, and the intracuff pressures in the control group were higher than in the intervention group. (P<0.001). CONCLUSION: Among this population, reduction of LMA AMBU® AuraOnce™ intracuff pressure to 30-32cm H2O reduces the occurrence and severity of POST. The LMA cuff pressures should be measured routinely using manometry and reducing the intracuff pressures to 30-32 cm of H2O recommended as best practice.

Perforación faríngea traumática secundaria a sindesmofito / Traumatic pharyngeal perforation secondary to a syndesmophyte

Se trata de un paciente varón, de 57 años, que acude al servicio de urgencias tras traumatismo facial y craneoencefálico al caerse por las escaleras. El paciente refiere cefalea intensa, motivo por el cual se le solicita una tomografía computarizada craneal donde se objetivan burbujas aéreas en espacio retrofaríngeo. Dado este hallazgo, se decide ampliar el estudio a región cervical y valorar así la posibilidad de perforación faríngea. Las perforaciones faríngeas en el contexto traumático son poco frecuentes, pero más aún lo son las causadas por la calcificación del ligamento longitudinal anterior como en nuestro caso

We report the case of a 57-year-old man who presented at the emergency department with injuries to his face and head after falling down the stairs. A head computed tomography examination done because he complained of an intense headache revealed air bubbles in the retropharyngeal space. Given this finding, a computed tomography of the neck was done to evaluate the possibility of pharyngeal perforation. Traumatic pharyngeal perforations are uncommon, but those caused by the calcification of the anterior longitudinal ligament, as in our case, are even more uncommon

Pharyngeal trauma in dairy cattle: 27 cases.

BACKGROUND: Characterization of the clinical signs, response to treatment and prognosis can be useful information for decision-making when evaluating cattle with pharyngeal trauma. OBJECTIVE: To describe the signalment, history, clinicopathologic, endoscopic, ultrasonographic, radiographic, and postmortem findings as well as treatments and outcomes of cattle diagnosed with pharyngeal perforation/trauma. ANIMALS: Review of medical records of cattle >1 month of age admitted to a Veterinary Teaching Hospital from 1995 to 2017. METHODS: Retrospective study. Review of medical records of cattle with pharyngeal perforation/trauma identified by oral or endoscopic examination in hospital setting. RESULTS: Twenty-seven out of 7550 (0.36%) cases met the inclusion criteria. Pharyngeal perforation/trauma was associated with the administration of a bolus in 24 (89%) cows and a magnet in 3 (11%) cases. The boluses contained monensin (n = 12), calcium salts (n = 5), iodine (n = 1), aspirin (n = 1), vitamins (n = 1), and an unknown product (n = 4). The primary clinical signs were dysphagia, swelling of the throatlatch, subcutaneous emphysema, swelling, and pain on palpation of the throatlatch. Seventeen (63%) cows were discharged whereas 10 (37%) were euthanized. Median time between the suspected traumatic event and hospital admission was 1 day (range: 0.5-3 days) and 2 days (range: 0.5-15) for surviving and nonsurviving cattle, respectively. All 5 cows that suffered pharyngeal trauma associated with administration of calcium salt bolus were euthanized. CONCLUSIONS AND CLINICAL IMPORTANCE: Pharyngeal trauma is a rare condition in cattle. Case fatality rate increases if not diagnosed and treated promptly. The nature of the penetrating foreign body influences the outcome.

Anterior cervical spine surgical site infection and pharyngoesophageal perforation. Ten-year incidence in 1475 patients.

BACKGROUND: Surgical site infection is reputed to be infrequent in anterior cervical spine surgery. Data on pathophysiological mechanism and risk factors are sparse. The relationship between local site infection and pharyngoesophageal perforation is unclear. The present study aimed: (1) to estimate the incidence of surgical site infection in anterior cervical spine surgery, (2) estimate the incidence of associated pharyngoesophageal perforation, and (3) suggest a decision-tree for early management of this two-fold issue. HYPOTHESIS: Although with very low incidence, anterior cervical spine surgical site infection and pharyngoesophageal perforation are frequently associated. MATERIAL AND METHODS: A 2-center retrospective study included all anterior cervical spine surgeries between January 1, 2007 and December 31, 2016. Data were provided by the two medical information departments. Patients undergoing anterior revision surgery on the cervical spine were included. Files were analyzed to determine whether the revision surgery was secondary to surgical site infection. RESULTS: In total, 1475 patients with anterior cervical spine surgery were identified: 1180 in center A (80%) and 295 in center B (20%). The rate of revision surgery for surgical site infection was 0.34% (5/1475). There were 3 cases of pharyngoesophageal perforation (0.2%). DISCUSSION: The incidence of revision surgery for anterior cervical spine surgical site infection was comparable to rates in the international literature (0.07-1.6%). An association between surgical site infection and pharyngoesophageal perforation was frequent, but not statistically significant. This complication is extremely serious, requiring urgent multidisciplinary management. LEVEL OF EVIDENCE: IV, retrospective study.

LMA® Protector™ versus traditional LMA to perform endobronchial ultrasound-guided transbronchial needle aspiration: a retrospective analysis.

BACKGROUND: The aim of this study was to evaluate the use of laryngeal mask airway (LMA)® Protector™ by comparison with traditional LMA for performing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). METHODS: This was a retrospective observational single-center study including 143 patients who underwent EBUS-TBNA for mediastinal staging of lung cancer. Patients were retrospectively divided into two groups based on whether a traditional LMA (traditional LMA group) or LMA Protector was used. Anesthesiologist outcomes, diagnostic yield of EBUS-TBNA, and complications related to the procedure were computed for each group and statistically compared. RESULTS: LMA traditional group and LMA Protector group counted 70 and 73 patients, respectively. LMA traditional group versus LMA Protector group showed no significant difference on time of LMA insertion (120±25 vs. 118±39 s; P=0.49), reposition rates (18% vs. 16%; P=0.78); systolic pressure (140±55 vs. 118±37 mmHg; P=0.59); diastolic pressure (82±15 vs. 90±26 mmHg; P=0.39); heart rate (82±9.9 vs. 83±20 bpm; P=0.49); SpO2 values (93±21% vs. 92±14%; P=0.63); diagnostic accuracy (91.3% vs. 92%; P=0.95), and patients' complications as nausea (4% vs. 3%; P=0.61); vomiting (3% vs. 1%, P=0.96); gastric aspiration (7% vs. 1%; P=0.08); and sore throat (7% vs. 3%; P=0.22). Conversely, LMA traditional group versus LMA Protector group presented a longer procedural time (47±23 vs. 38±17 s; P=0.02), higher number of passage to biopsy target lesion (4±0.5 vs. 3.1±0.6; P=0.01); higher rate of balloon ultrasound rupture (11% vs. 1%; P=0.01). CONCLUSIONS: EBUS-TBNA conducted with LMA Protector is a useful strategy that reduced the procedural time and in theory ensured the comfort of patients. Our results should be confirmed by larger, prospective, randomized studies.

Traumatic pharyngeal perforation secondary to a syndesmophyte. / Perforación faríngea traumática secundaria a sindesmofito.

We report the case of a 57-year-old man who presented at the emergency department with injuries to his face and head after falling down the stairs. A head computed tomography examination done because he complained of an intense headache revealed air bubbles in the retropharyngeal space. Given this finding, a computed tomography of the neck was done to evaluate the possibility of pharyngeal perforation. Traumatic pharyngeal perforations are uncommon, but those caused by the calcification of the anterior longitudinal ligament, as in our case, are even more uncommon.

Traumatic Injuries of the Ear, Nose and Throat.

This article reviews the presentation, diagnosis, and management of common traumatic injuries of the ear, nose, and throat, including laryngeal trauma, auricular and septal hematomas, and tympanic membrane rupture.
