Background: Mediastinal masses comprise of a wide variety of tumors and accounts for about 3% of tumors within the chest. Very few studies have been produced so far on large anterior mediastinal masses, as this pathology is infrequently encountered in clinical practice and tend to be asymptomatic until compression symptoms occur, which leads to mediastinal mass syndrome (MMS). The aim of this writing is to assess the surgical feasibility, approach, safety of resection and outcome in large anterior mediastinal masses.Methods: A retrospective review was conducted on patients referred for mediastinal mass to the Thoracic Surgery Unit, Hospital Kuala Lumpur from October 2017 until March 2020 (30 months). Patients with evidence of primary anterior mediastinal mass measuring >6 cm on contrast-enhanced computed tomography (CECT) of thorax and had undergone treatment in our centre were included. Data were analysed by proportions, means and standard deviations. Categorical data were expressed as percentage, whereas interquartile range was used to describe continuous variables.Results: Out of 63 patients with anterior mediastinal mass, 16 (25.4%) patients had anterior mediastinal mass larger than 6 cm and was included in the analysis. The average tumor size was 11.9 cm. Five patients (31.3%) had MMS. Twelve out of 16 patients were operated with 75% rate of clear tumor margin. There was no postoperative mortality recorded within 30 days of surgery.Conclusions: Positive outcome of definitive surgery in this series suggests clinical feasibility with acceptable short-term safety. Multidisciplinary approach with adequate preoperative assessment, intraoperative preparation and short-and long-term postoperative care were key features to successful treatment of this disease.

Background The Covid-19 pandemic has caused changes in the surgical treatment of non-Covid patients, especially in thoracic surgery because most procedures are aerosol generating. Hospital Kuala Lumpur, where thoracic procedures are performed, was badly affected. We describe our experience in performing aerosol generating procedures safely in thoracic surgery during the Covid-19 era. Methods Medical records of patients who underwent thoracic surgery from March 18, 2020 to May 17, 2020 were reviewed retrospectively. All patients undergoing thoracic surgery were tested for Covid-19 using the reverse transcriptase polymerase chain reaction method. Patients with malignancy were observed for 10 to 14 days in the ward after testing negative. The healthcare workers donned personal protective equipment for all the cases, and the number of healthcare workers in the operating room was limited to the minimum required. Results A total of 44 procedures were performed in 26 thoracic surgeries. All of these procedures were classified as aerosol generating, and the mean duration of the surgery was 130 ± 43 minutes. None of the healthcare workers involved in the surgery were exposed or infected by Covid-19. Conclusion Covid-19 will be a threat for a long time and thoracic surgeons must continue to provide their services, despite having to deal with aerosol generating procedures, in the new normal. Covid-19 testing of all surgical candidates, using the reverse transcriptase polymerase chain reaction, donning full personal protective equipment for healthcare workers, and carefully planned procedures are among the measures suggested to prevent unnecessary Covid-19 exposure in thoracic surgery.

Tracheal bronchus is a rare, congenital abnormality of the tracheobronchial tree. Majority of patients with tracheal bronchus are asymptomatic. Lung malignancy associated with tracheal bronchus is rare. An asymptomatic 40-year-old female was diagnosed with right upper lobe lung carcinoma. CT thorax revealed a right upper lobe tracheal bronchus. The patient underwent right uniportal video-assisted thoracoscopic (VATS) lobectomy and recovered well. To our knowledge, this is the first reported case of primary lung carcinoma with tracheal bronchus treated with right uniportal VATS upper lobectomy in Malaysia, and the second reported case internationally.
