The incidence of lung nodules has increased with improved diagnostic imaging and screening protocols. Despite improvements for diagnosing pulmonary nodules with technologies such as electromagnetic navigational bronchoscopy (ENB), several limitations still exist including adequate visualization, localization, and diagnostic yield. Robotic-assisted bronchoscopy with ENB has been introduced as a method to overcome these shortcomings. We describe our initial experience in evaluating lung nodules with robotic assisted bronchoscopy. We retrospectively reviewed data on the first 25 patients that underwent robotic-assisted bronchoscopy and biopsy. We analyzed success with localization, diagnostic yield, and post procedural morbidity. Diagnostic yield was 96% (24/25) with no periprocedural morbidity. The majority of nodules were malignant or atypical (76%) and were located in the right upper lobe. Diameter ranged between 0.8–6.9 cm (median size 1–2 cm). Seventy-five percent of patients underwent subsequent treatment for cancer based on these results, with 25% having continued surveillance. Robotic assisted bronchoscopy is safe and accurate. Studies with larger numbers will allow better understanding of the diagnostic yield and clinical utility of this approach in comparison to other diagnostic tools for lung nodules.

Robot-assisted surgery for anterior mediastinal mass resection has been increasingly adopted as an alternative method to open sternotomy and conventional video-assisted thoracic surgery. However, more evidence is needed to expand the indication of this technique to more complicated cases. We present a case of robot-assisted resection of a 7-cm anterior mediastinal mass with pericardium and adjacent lung for thymic squamous cell carcinoma, accompanied by reconstruction of pericardium with polytetrafluoroethylene patch. In conclusion, complex anterior mediastinal mass excision is feasible with robotic thoracic surgery.

Background:New neurologic manifestations of the SARs-CoV-2 virus are emerging. We report a rare case of unilateral diaphragm paralysis following COVID-19 infection. Case Presentation:A 55 year-old previously healthy person was infected with SARs-CoV-2 prior to the availability of a vaccine. This patient was intubated and pronated for respiratory failure. For 6-months after recovery he experienced new debilitating dyspnea and orthopnea. Dynamic chest radiography demonstrated severely impaired motion of the right hemidiaphragm, representing a new hemi-diaphragm paralysis. After surgical plication the symptoms resolved. Conclusions:This case demonstrates the importance of thorough evaluation for diaphragm paralysis in patients who have suffered COVID-19 infection when there is persistent dyspnea or orthopnea, as well as the neuroinvasive potential of the virus that has yet to be fully explained.
