Cardiac Hemangioma Producing Pericardial Effusion Detected on Thoracoscopic Pericardial Fenestration.

A 76-year-old woman presented with dyspnea. Computed tomography showed massive pericardial effusion, so percutaneous catheter drainage was performed. The usual causes of exudate were ruled out, and no diagnosis was reached. Thoracoscopic pericardial fenestration was performed to obtain a pericardial biopsy specimen and to create a passage allowing longer-term drainage. Observation of the pericardial cavity after the effusion was removed incidentally revealed a tumor measuring 2 cm in diameter located between the left atrial appendage and left pulmonary artery. Surgical resection of the tumor attached to the left atrial appendage was performed. The pathologic diagnosis was hemangioma.

Imaging of therapeutic airway interventions in thoracic oncology.

Tracheobronchial obstruction, haemoptysis, and airway fistulas caused by airway involvement by primary or metastatic malignancies may result in dyspnoea, wheezing, stridor, hypoxaemia, and obstructive atelectasis or pneumonia, and can lead to life-threatening respiratory failure if untreated. Complex minimally invasive endobronchial interventions are being used increasingly to treat cancer patients with tracheobronchial conditions with curative or, most often, palliative intent, to improve symptoms and quality of life. The selection of the appropriate treatment strategy depends on multiple factors, including tumour characteristics, whether the lesion is predominately endobronchial, shows extrinsic compression, or a combination of both, the patient's clinical status, the urgency of the clinical scenario, physician expertise, and availability of tools. Pre-procedure multidetector computed tomography (MDCT) imaging can aid in the most appropriate selection of bronchoscopic treatment. Follow-up imaging is invaluable for the early recognition and management of any potential complication. This article reviews the most commonly used endobronchial procedures in the oncological setting and illustrates the role of MDCT in planning, assisting, and follow-up of endobronchial therapeutic procedures.

Silicone Stent Versus Fully Covered Metallic Stent in Malignant Central Airway Stenosis.

BACKGROUND: Airway stenting to restore airway patency in cases of malignant central airway obstruction is an effective palliation treatment. Our goal was to compare the efficacy after deployment and complications of a fully covered self-expandable metal stent (SEMS) (Aerstent) and a silicone stent (Dumon). METHODS: This was a retrospective cohort of 2 similar groups of patients with malignant central airway obstruction treated with stents between August 2012 and July 2017. Complications were assessed bronchoscopically. A competing risk for death analysis was performed to adjust the probability of developing a complication. RESULTS: Seventy patients (29 with silicone stents and 41 with SEMS) were included. Stent insertion was successful in all cases. Mucus retention was the most frequent complication (75.9% with silicone stents and 84.8% with SEMS; P = .51), followed by granulation tissue (51.7% with silicone stents and 41.3% with SEMS; P = .52) and migration (6.9% with silicone stents and 13.0% with SEMS; P = .47). In the first month, the cumulative incidence of a complication was 36.7% for silicone stents and 41.3% for SEMS and increased to 90.0% and 97.8% after 6 months, respectively (hazard ratio = 1.66; P = .04). A competing risk for death analysis showed an adjusted hazard ratio of 1.41 (P = .49) indicating no differences in overall complications between stents. CONCLUSIONS: Both stents were equally successful and safe. The incidence of complications increased over time to 90% at 6 months for both stents. The risk of overall complications was higher for SEMS; nevertheless, when mortality was measured in a competitive risk analysis, no differences were found between SEMS and silicone stents.

Indications and clinical outcomes of fully covered self-expandable metallic tracheobronchial stents in patients with malignant airway diseases.

BACKGROUND: Airway stenting is an efficacious approach in management of malignant airway disease (MAD) with improvement in survival outcome. OBJECTIVE: To determine the indications and long-term clinical outcomes of tracheobronchial stenting in patients with MAD. METHODS: A cross-sectional review of 51 patients who underwent airway stenting from June 2011 to June 2019 was done. Paired t-test was used to compare mean difference of clinical characteristics between pre- and post-airway stenting. Kaplan-Meier curves were used to assess overall survival. RESULTS: A total of 51 patients had stent insertion with mean age 46.63±17.10years including 27(52.9%) females. Mainly 37(72.5%) patients had esophageal and 06(11.8%) had lung cancer. The main indications were bronchial stenosis 18(35.3%), tracheal stenosis 11(21.6%) and Tracheo-esophageal/bronchial fistula 13(25.5%). Obstruction was intrinsic, extrinsic and mixed in 20(39.2%), 13(25.5%) and 5(9.8%) patients, respectively. There was statistically significant mean difference in pre- and post-procedure oxygen saturation (mean (M)=89.8, standard deviation (SD)=6.70 vs M =95.5,SD=2.54.p =0.001) and performance status (M =3.65,SD =0.6 vs M =2.59, SD=0.83.p =0.001). Overall median survival was 16±3.44 weeks, highest amongst patients with intrinsic obstruction (27±6.51 weeks). CONCLUSION: Airway stenting is an effective endoscopic procedure to re-establish airway patency in MAD with minimal complications..

Electrosurgical and Laser Therapy Tools for the Treatment of Malignant Central Airway Obstructions.

Central airway obstruction (CAO) is associated with significant morbidity and increased mortality. Bronchoscopic electrosurgical and laser ablative tools have proven to be safe and effective instruments for the treatment of malignant CAO. Although therapeutic modalities such as electrocautery, argon plasma coagulation, and laser have been used for decades, additional tools including radiofrequency ablation catheters continue to be developed for the treatment of CAO. These modalities are considered safe in the hands of experienced operators, although serious complications can occur. This review describes various electrosurgical and laser therapy tools used for the treatment of malignant CAO along with the specific advantages and disadvantages of each device.

Clinical and radiographic predictors of successful therapeutic bronchoscopy for the relief of malignant central airway obstruction.

BACKGROUND: Malignant central airway obstruction (CAO) occurs in approximately 20-30% of patients with lung cancer and is associated with debilitating symptoms and poor prognosis. Multimodality therapeutic bronchoscopy can relieve malignant CAO, though carries risk. Evidence to guide clinicians regarding which patients may benefit from such interventions is sparse. We aimed to assess the clinical and radiographic predictors associated with therapeutic bronchoscopy success in relieving malignant CAO. METHODS: We reviewed all cases of therapeutic bronchoscopy performed for malignant CAO at our institution from January 2010-February 2017. Therapeutic bronchoscopy success was defined as establishing airway patency of > 50%. Patient demographics and baseline characteristics, oncology history, degree of airway obstruction, procedural interventions, and complications were compared between successful and unsuccessful groups. Univariate and multivariate logistic regression identified the significant clinical and radiographic predictors for therapeutic success. The corresponding simple and conditional odds ratio were calculated. A time-to-event analysis with Kaplan-Meier plots was performed to estimate overall survival. RESULTS: During the study period, 301 therapeutic bronchoscopies were performed; 44 (14.6%) were considered unsuccessful. Factors associated with success included never vs current smoking status (OR 5.36, 95% CI:1.45-19.74, p = 0.010), patent distal airway on CT imaging (OR 15.11, 95% CI:2.98-45.83, p < 0.0001) and patent distal airway visualized during bronchoscopy (OR 10.77, 95% CI:3.63-31.95, p < 0.001) in univariate analysis. Along with patent distal airway on CT imaging, increased time from radiographic finding to therapeutic bronchoscopy was associated with lower odds of success in multivariate analysis (OR 0.96, 95% CI:0.92-1.00, p = 0.048). Median survival was longer in the successful group (10.2 months, 95% CI:4.8-20.2) compared to the unsuccessful group (6.1 months, 95% CI:2.1-10.8, log rank p = 0.015). CONCLUSIONS: Predictors associated with successful therapeutic bronchoscopy for malignant CAO include distal patent airway visualized on CT scan and during bronchoscopy. Odds of success are higher in non-smokers, and with decreased time from radiographic finding of CAO to intervention.

An Open-label, Single-arm Study of CRYO2 for Debulking at the Site of Central Airway Obstruction or Stenosis.

BACKGROUND: An open-label, single-arm study was conducted to assess the safety of a cryosurgery unit named CRYO2 for debulking at the site of obstruction or stenosis. PATIENTS AND METHODS: In order to treat central airway tumor-related stenosis, debulking at the stenotic site of the airway was performed using CRYO2 under general or local anesthesia. The primary endpoint was the incidence of moderate to massive hemorrhage. RESULTS: Incidence of moderate to massive hemorrhage during surgery was 3.8% (1/26) (95% confidence interval(CI)=0.1-19.6%). Technical success was 96.2% (25/26), with a 95% confidence interval of 80.4-99.9%. CONCLUSION: CRYO2 for debulking at the site of obstruction or stenosis can be performed safely.

Long-term quality-adjusted survival following therapeutic bronchoscopy for malignant central airway obstruction.

BACKGROUND: While therapeutic bronchoscopy has been used to treat malignant central (CAO) airway obstruction for >25 years, there are no studies quantifying the impact of therapeutic bronchoscopy on long-term quality-adjusted survival. METHODS: We conducted a prospective observational study of consecutive patients undergoing therapeutic bronchoscopy for CAO. Patients had follow-up at 1 week and monthly thereafter until death. Outcomes included technical success (ie, relief of anatomic obstruction), dyspnoea, health-related quality of life (HRQOL) and quality-adjusted survival. RESULTS: Therapeutic bronchoscopy was performed on 102 patients with malignant CAO. Partial or complete technical success was achieved in 90% of patients. At 7 days postbronchoscopy, dyspnoea improved (mean ∆Borg-day-7=-1.8, 95% CI -2.2 to -1.3, p<0.0001) and HRQOL improved (median prebronchoscopy 0.618 utiles, 25%-75% IQR 0.569 to 0.699, mean ∆utility-day-7+0.047 utiles, 95% CI +0.023 to 0.071, p=0.0002). Improvements in dyspnoea and HRQOL were maintained long-term. Compared with the prebronchoscopy baseline, HRQOL per day of life postbronchoscopy improved (mean ∆utility-long-term+0.036 utiles, 95% CI +0.014 to 0.057, p=0.002). Median quality-adjusted survival was 109 quality-adjusted life-days (QALDs) (95% CI 74 to 201 QALDs). Factors associated with longer quality-adjusted survival included better functional status, treatment-naïve tumour, endobronchial disease, less dyspnoea, shorter time from diagnosis to bronchoscopy, absence of cardiac disease, bronchoscopic dilation and receiving chemotherapy. CONCLUSIONS: Therapeutic bronchoscopy improves HRQOL as compared with baseline, resulting in approximately a 5.8% improvement in HRQOL per day of life. The risk-benefit profile in these carefully selected patients was very favourable. TRIAL REGISTRATION NUMBER: Results; NCT03326570.

Tracheobronchial stents in palliative care: a case series and literature review.

OBJECTIVE: To evaluate the outcomes of tracheobronchial stenting in patients with malignant central airway obstruction and assist practitioners in palliative settings in understanding the indications, contraindications and management of tracheobronchial stents. METHODS: This retrospective study involved a consecutive case series of palliative patients with central airway obstruction secondary to inoperable cancers who underwent tracheobronchial stenting at a single institution. The European Cooperative Oncology Group (ECOG) scale was used to evaluate patient functional status before and after tracheobronchial stenting. RESULTS: Twenty-three patients underwent tracheobronchial stenting for malignant central airway obstruction. The majority of patients presented with symptoms of worsening dyspnoea (21 of 23; 91%). Postoperatively, there was a significant improvement in mean ECOG performance status from 2.88±0.34 to 1.58±0.50 (p<0.01). There was no intraoperative mortality resulting from tracheobronchial stenting. Five patients (21.74%) re-presented to hospital due to worsening symptoms and required emergency bronchoscopy. Two patients had stent migration, requiring stent replacement. One patient restenosed from tumour granulation, requiring microdebrider to debulk the mass. Two patients had stent failure secondary to external tumour compression, leading to death. CONCLUSION: Tracheobronchial stenting is a safe and effective procedure that offers rapid palliation of symptoms and improvement in patient functional status.

Management of Infantile Hemangiomas of the Airway.

Infantile hemangiomas (IHs) of the airway are far less common than their cutaneous counterparts, and their symptoms mimic those of viral croup. As a result, by the time these lesions are diagnosed, they are often advanced and causing airway compromise. Fortunately, the evolution of propranolol as an effective and safe pharmacotherapy has simplified management of IH and reduced the likelihood of complications previously seen with steroid therapy and surgery. Nevertheless, the otolaryngologist must be prepared with an alternate plan to manage lesions refractory to pharmacotherapy. This article reviews the clinical presentation and current management of IHs of the airway.

The Management of Vascular Malformations of the Airway: Natural History, Investigations, Medical, Surgical and Radiological Management.

Vascular malformations may affect nearly all aspects of the upper airway. Each type of malformation has a characteristic pattern of disease. These lesions may be focal or diffuse, and require directed management strategies. Physicians treating these entities should have a high level of suspicion to consider airway evaluation even in the absence of overt symptoms. However, cutaneous head and neck venous malformations or other lesions affecting the lips, oral cavity, or tongue can herald the presence of coexisting airway lesions. A multidisciplinary approach is critical in achieving comprehensive treatment.

Rescue transtracheal jet ventilation during difficult intubation in patients with upper airway cancer.

INTRODUCTION: The failure rates of intubation and/or mask ventilation are higher in patients with neck or upper airway disease. To ensure oxygenation, rescue trans-tracheal jet ventilation (RTTJV) may be used. In this critical situation, a high rate of complications has been reported. The aim of this study was to report RTTJV performed by a jet ventilator with an end-expiratory pressure control in an experienced institution. PATIENTS AND METHODS: From a computerised database of 63,905 anaesthesia cases, the anaesthetic reports of patients who underwent emergency RTTJV during intubation were studied retrospectively. The following information were analysed: anaesthetic procedures, data from the monitoring: lowest SpO2, duration of SpO2<90%, and complications. Success of emergency RTTJV was defined when SpO2 was>90% under jet ventilation. RESULTS: RTTJV was used in 31 patients, of whom 26 had upper airway cancer, (pre-treatment, n=9, post-treatment, n=17). Difficult intubation was anticipated in 15 out of 31 cases including six fiber-optic-aided intubations under spontaneous ventilation. RTTJV was effective in all cases with quick restoration of oxygenation (SpO2>90%). During jet ventilation, final airway control was performed either by oral intubation (n=25) or tracheotomy (n=1) in a short delay (mean: 8.1±1.7min). Subcutaneous emphysema was observed in one case without pneumothorax. CONCLUSION: RTTJV with end-expiratory pressure control allowed oxygenation during difficult intubation, with a low rate of complications.

Hernia of the swim bladder (aerocystocele) with concurrent mycotic granulomatous inflammation and swim bladder carcinoma in a wild mullet (Mugil cephalus).

We describe a hernia of the swim bladder, with a concurrent mycotic granulomatous inflammation, and carcinoma of the swim bladder in a wild mullet (Mugil cephalus) referred for an exophytic dorsal mass. Grossly, the mass was white, soft, and composed of multiple cystic gas-containing chambers connected by a funnel-shaped tissue segment to the coelomic swim bladder. Histologically, the mass was characterized by cysts of variable size, multifocally contiguous with the subepithelial rete mirabile, supported by abundant fibrous tissue. The skin covering the herniated swim bladder was focally ulcerated and replaced by abundant granulation tissue in which multiple scattered granulomas centered on pigmented fungal hyphae were observed. These granulomas were also seen in the remaining coelomic portion of the swim bladder as well as in the spleen, perivisceral pancreas, and peritoneal adipose tissue; the fungus was molecularly identified as Cladosporium spp. Focally, arising from the herniated swim bladder epithelium, an unencapsulated poorly demarcated, moderately cellular neoplasm, composed of islands, lobules, and acini of neoplastic epithelium, was found.

Pharmacological Management of Bronchorrhea in Malignant Disease: A Systematic Literature Review.

CONTEXT: Malignant respiratory tract tumors can lead to massive fluid production, known as bronchorrhea. This symptom can be very distressing itself, and it can lead to or aggravate other symptoms such as dyspnea and cough. Pharmacological treatment options have been reported in the literature. However, no systematic evaluation of their effectiveness has been conducted so far. OBJECTIVES: To systematically identify, appraise, and evaluate the effectiveness of symptomatic pharmacological treatment of bronchorrhea in malignant disease in palliative care. METHODS: A systematic literature review in Medline, Embase, and the Cochrane Database, as well as citation tracking, hand searches of selected journals, and reference lists of retrieved articles, was performed. For the purpose of this review, only symptomatic treatments were considered. RESULTS: No controlled clinical studies could be identified. Twenty of 48 retrieved references were analyzed in detail. These 20 case reports and case series dealt with the symptomatic pharmacological management of bronchorrhea in malignant disease; the other 28 had to be excluded for various reasons. The majority of patients suffered from bronchioloalveolar carcinoma. Reported treatments comprise corticosteroids, macrolide antibiotics, inhaled indomethacin, octreotide, and tyrosine-kinase inhibitors. For some drugs, significant clinical impact on distressing symptoms associated with bronchorrhea was reported. CONCLUSION: There are only very limited data on the pharmacological management of bronchorrhea in malignant disease. Because of the distressing nature of the symptom, a pragmatic management strategy is essential. This can include promising treatment options reported in the literature but should also take into account availability, individual tolerability, and costs. Further research is needed.

Acoustical and Perceptual Voice Profiling of Children With Recurrent Respiratory Papillomatosis.

OBJECTIVES: Respiratory papillomatosis is a condition characterized by benign papillomatous (wart-like) growths in the respiratory tract. The condition tends to recur after treatment, requiring multiple procedures to control growth of the lesions. In such cases, the condition is known as recurrent respiratory papillomatosis (RRP). This study aims at providing comparative measures of acoustic as well as perceptual voice analysis of children with RRP. METHODS: Ten children with a history of RRP for a minimum of 3 years were selected under purposive sampling. A detailed case history, Clinical Assessment Scale of RRP, and laryngostroboscopy findings were done. This was followed by perceptual voice assessment using Buffalo III Voice Screening Profile, and acoustical voice assessment using Dr. Speech software (by Tiger DRS, Inc.). Group statistics and t test were used at a significance level of 0.05 (SPSS package Version 12.0 is used which is manufactured by IBM Corporation). RESULTS: Both groups with RRP showed substantial difference in habitual F0, S/Z ratio, Signal to Noise Ratio (SNR), Harmonic to Noise Ratio (HNR), and Maximum Phonation Time (MPT) voice parameters. On perceptual analysis, all children with RRP had hoarse voice quality, and stridors are present. CONCLUSIONS: All children with RRP have affected voice parameters in some extent which depend on the period and area of lesion.

Influence of pharyngolaryngeal anomalies diagnosed through indirect laryngoscopy in the prediction of difficult intubation.

OBJECTIVE: To determine the pharyngolaryngeal anomalies not usually included in the evaluation of difficult airway, in order to investigate the influence of these anomalies in the prediction of difficult intubation. To do this, indirect laryngoscopy with a 70° rigid laryngoscope was performed on all patients during the preoperative period. METHODS: This is an observational, prospective study on 300 consecutive patients who were scheduled for endotracheal intubation under general anesthesia. In addition to assessing the airway in the preoperative period by demographic and clinical predictors of difficult airway, rigid indirect laryngoscopy was performed to diagnose pharyngolaryngeal anomalies. Later, under general anesthesia and direct laryngoscopy it was checked to see if there was difficulty in intubating the larynx, and its association with all previous variables was investigated. A logistic regression model for prediction purposes was developed, and its power of discrimination was achieved by assessing the area under the curve. RESULTS: During the examination by indirect laryngoscopy 46 anomalies were found, which were as follows: 31 abnormalities of the epiglottis (22 omega epiglottis, 9 flaccid or hypertrophic epiglottis); 6 findings of hypertrophic lingual tonsils, 3 cases of upper airway tumors, and 6 patients with tongue disorders. Intubation difficulty was found in 14 cases (4.66%). The regression model found, and its coefficients to develop it were: f(x)=1.322+(2.173 thyromental distance <6.5 cm)+(1.813 omega epiglottis)-(1.310*cm opening mouth). Global power of discrimination was 0.83, with a 95% confidence interval from 0.709 to 0.952). CONCLUSION: Indirect laryngoscopy allowed pharyngolaryngeal anomalies to be diagnosed, including omega epiglottis, which was one of the variables included in the logistic regression model.

[Home parenteral nutrition in elderly patients with cancer: an observational prospective study]. / Nutrition parentérale à domicile chez la personne âgée atteinte d'un cancer: une étude observationnelle prospective.

Malnutrition is a bad prognostic factor that reduces the quality of life (QoL) in patients with cancer. The objective was to assess the impact of home parenteral nutrition (HPN) on the QoL of elderly malnourished patients with cancer. This French prospective observational study included patients, aged 70 years or older, with cancer, for whom HPN was prescribed for at least 14 days. The patient, the physician and a family member or home caregiver had to fill in a questionnaire at inclusion and 28 days later. Included patients (n = 221) were mainly suffering from a digestive cancer. After HPN intake, improved weight was noticed in 68% and 14% of patients had reached the target weight. Improved global QoL was reported in 59% of patients. Physicians noticed a significant improvement for the same compounds. These results suggest a benefit of the HPN on the nutritional status and QoL in elderly patients with cancer. Further controlled randomised trials are needed to prove the benefit of HPN in the routine management of these patients.
