The laryngeal mask airway, the LMA® Gastro™ (Teleflex Medical, Athlone, Ireland), is a novel airway device which permits upper gastrointestinal (GI) endoscopy to be performed via a dedicated large calibre oesophageal lumen. It has been validated in adult studies, but to our knowledge, there have been no data published regarding its use in a paediatric population. Following a brief education programme, the LMA Gastro was introduced on a trial basis at our institution and made freely available. Over a four-month period, our pre-existing endoscopy audit framework captured data on a total of 55 patients who had the LMA Gastro device chosen as the primary airway for elective upper GI endoscopy. These data were collected prospectively by the treating anaesthetist and included a range of airway and endoscopy outcomes. Of the 55 patients, the LMA Gastro provided an adequate airway in 52 (94.5%). Forty-six (88.5%) were sited on first attempt, and 50 (96.2%) insertions were rated 'easy' by the anaesthetist. Aside from three insertion failures, there were no airway events. The endoscopy success rate was 100% in the 52 patients who had an LMA Gastro airway successfully inserted. First-pass oesophageal access was achieved in 51 (98%) cases, and 100% of insertions were rated 'easy' by the gastroenterologist. Despite our relative inexperience with it, the device had a high success rate for airway maintenance and oesophageal access in our paediatric patient population. In our institution, the LMA Gastro provided a useful airway option in older children undergoing elective upper GI endoscopy.
Pulmonary carcinoids are rare neoplasms, accounting for approximately 1%-2% of all lung malignancies. A retrospective analysis was undertaken of all patients who underwent surgical resection of pulmonary carcinoid tumours across multiple institutions in Melbourne, Australia.
From May 2000 through April 2020, 241 patients who underwent surgical resection of pulmonary carcinoid tumours were retrospectively reviewed. Patient demographics, pathologic data, and long-term outcomes were recorded.
Median age was 57.7 years and the majority of patients were female (58.9% vs. 41.1%). Typical carcinoid was present in 77.1%. Histological subtype was associated with several factors. Atypical carcinoid was more likely to have larger tumour size and nodal involvement. Overall survival for typical carcinoid at 5, 10, and 15 years was 98%, 95%, and 84%, and for atypical carcinoid was 88%, 82%, and 62%, respectively. Histological subtype and age were found to be independent predictors of overall survival, with worse outcarcinoid tumour without nodal involvement may be appropriate for sublobar resection. Typical and atypical carcinoid tumours should be considered distinct disease entities, and as such treated accordingly.
Although carotid artery disease can occur in patients who have coronary artery disease (CAD), ostial stenosis of a left common carotid artery (CCA) along with CAD is a rarely reported condition.
We describe a rare case of severe stenosis of the left CCA ostium and CAD, which were successfully treated with an off-pump coronary artery bypass and aorto-left CCA bypass. This strategy minimizes the risk of perioperative strokes. CDK inhibitor Furthermore, an aorto-supra aortic trunk bypass provides a more physiological blood flow pattern than cerebral approaches. This approach would be a safe and effective treatment option.

Pneumomediastinum (PM) is associated with several etiologies and mechanisms. Although it has been described more than 100 years ago, the literature is limited to small retrospective studies. This study aimed to follow patients with coronavirus disease (COVID-19) that developed PM during hospitalization and describe their clinical and radiological evolution.
A prospective cohort was developed with patients with PM, excluding those with aerodigestive trauma, inside a hospital COVID-19 dedicated hospital. Clinical variables including onset of symptoms, hemodynamic instability, associated complications, the need of interventions, and disease course were all recorded. Also, radiological findings such as the presence of the Macklin effect, extension of lung involvement by COVID-19, and characteristics of the PM were analyzed.
Twenty-one patients with non-traumatic PM were followed, resulting in an overall incidence of 0.5% during the study period. Seven (33%) patients had associated pneumothorax and malignant/tension PM was observed in three (14%) cases. The Macklin effect could be found in 11 patients (52%) and the majority of them had more than 50% of lung involvement due to COVID-19. The mortality rate was 49%; however, no deaths were directly related to the PM.
PM incidence is probably increased in the severe acute respiratory syndrome caused by COVID-19, especially in those with greater involvement of the lungs, and the Macklin effect may be an important underlying mechanism of this complication. Usually, PM has a benign course, but complications like tension/malignant PM may occur requiring prompt detection and intervention.

Pulmonary complications after cardiac surgery are very common and lead to an increased incidence of post-operative morbidity and mortality. Several factors, either modifiable or non-modifiable, may contribute to the associated unfavorable consequences related to pulmonary function. This study was aimed to investigate the degree of alteration and factors influencing pulmonary function (forced expiratory volume in one second (FEV
) and forced vital capacity), on third, fifth, and seventh post-operative days following cardiac surgery.
This study was executed in 71 patients who underwent on-pump cardiac surgery. Pulmonary function was assessed before surgery and on the third, fifth, and seventh post-operative days. Data including surgical details, information about risk factors, and assessment of pulmonary function were obtained.
The FEV
and forced vital capacity were significantly impaired on post-operative days 3, 5, and 7 compared to pre-operative values. The reduction in FEV
was 41%, 29%, and 16% and in forced vital capacity was 42%, 29%, and 19% consecutively on post-operative days 3, 5, and 7.
