The surgical approach of late-onset tracheoesophageal fistula in a tracheostomized COVID-19 patient.

In the COVID-19 era the tracheal complications due to prolonged mechanical ventilation have significantly increased. Acquired tracheoesophageal fistula is one of those in ventilated COVID-19 patients. Thus, the knowledge of their management in such fragile patient is crucial. We report a case of tracheoesophageal fistula in a 56-year-old female under prolonged mechanical ventilation for COVID-19 bilateral pneumonia and discuss its management. A surgical approach was proposed. By a collar-shaped transverse cervicotomic access, we transected the trachea at level of fistula en-bloc with the tracheostoma. The esophageal lesion was longitudinally repaired in two-layers. Protective left strap muscle was sandwiched between esophagus and trachea. The tracheal end-to-end anastomosis was completed without a re-tracheostoma. Even if surgical approach of tracheoesophageal fistula in COVID-19 patients has not been tested before, surgery remains the treatment of choice according to the multidisciplinary board.

Surgical management of tracheal chondrosarcoma.

Background: Tracheal chondrosarcoma is an extremely rare, slow-growing, malignant tumour. This study aims to analyze the cases of tracheal chondrosarcoma published in the literature and our case report, in order to better define tracheal chondrosarcoma management.Methods: A systematic review of the English literature was carried out for fully described tracheal chondrosarcoma cases. Additionally, we reported a new case of a 58-year-old man undergoing tracheal resection and reconstruction for tracheal chondrosarcoma.Results: To date, 30 cases were published. This tumour predominantly involved male patients (93%; median age: 65 years), generally conditioning dyspnoea and cough. Most of the patients underwent tracheal resection with end-to-end anastomosis, without recurrence (median follow-up: 2 years). Tumours endoscopically treated recurred in half cases.Conclusion: Tracheal resection is the treatment of choice for chondrosarcoma, with an excellent prognosis. Endoscopic treatment and/or radiotherapy should be indicated for patients unfit for surgery.

Energy devices safety and impact on video-assisted thoracoscopic lung lobectomy postoperative course: monopolar electrocautery versus ultrasonic dissector.

BACKGROUND: This study aims to compare safety and impact of monopolar electrocautery and ultrasonic dissector (Harmonic ACE Plus®) on postoperative short-term outcomes after video-assisted thoracoscopic (VATS) lobectomy and lymphadenectomy for lung cancer. METHODS: We analyzed the prospectively collected data of 140 consecutive patients [59% male; median age: 71(IQR:62-76) years] undergoing VATS lobectomy and lymphadenectomy in our institution between October 2016 and November 2019. Patients were divided in two groups based on device used: monopolar electric hook in 79 cases (Group A); ultrasonic dissector in 61(Group B). Energy instrument-related intraoperative accidents, hemothorax/chylothorax incidence, total pleural effusion volume at 48 postoperative hours and chest tube duration were compared between groups. Multivariable analysis was performed to test energy device as possible independent risk factor either for increased pleural effusion volume or for prolonged chest tube duration. RESULTS: No intraoperative accidents due to energy device occurred. No hemothorax was recorded. Postoperative chylothorax incidence was slightly higher in Group A (2.5% vs 0%; p-value = 0.21). Total pleural effusion volume at 48 h was significantly higher in Group B: 400 (285-500) vs 255 (150-459) ml (p-value = 0.005). Chest tube duration was similar in the two groups: 5 (3-9) vs 5 (3-8) days (p-value = 0.77). At multivariable analysis the energy device used was not associated with increased pleural effusion volume (p-value = 0.43) nor with prolonged chest tube duration (p-value = 0.28). CONCLUSIONS: Monopolar electrocautery and Harmonic ACE Plus® were safe and had a similar impact on short-term outcomes after VATS lobectomy and lymphadenectomy, suggesting that energy devices choice could be left to surgeon's preference.
