RESUMEN
Gender-specific differences in the diagnostics and treatment must be considered for various lung diseases. In the case of pneumothorax, in addition to differences in etiology there are also relevant differences in treatment and recurrence rates between men and women. For example, to achieve low recurrence rates catamenial pneumothorax requires interdisciplinary collaboration with gynecology. The incidence of lung cancer has equalized in recent years and in addition, various gender-specific prognostic factors have become relevant. Several meta-analyses have identified female gender as a positive prognostic factor for lung cancer, in addition to the higher prevalence of various driver mutations in women. In current trials of multimodal treatment for lung cancer, gender differences in tolerability and patient outcome are already apparent. In subgroup analyses better event-free survival was observed in women, although immune-mediated adverse events were more common in women.

OBJECTIVE: Thoracic neurogenic tumors usually present as benign nerve sheath tumors that can be resected via transthoracic or posterior approaches, depending on the anatomical location. Robot-assisted thoracic surgery (RATS) is increasingly being used for the transthoracic approach, but evidence is very limited. The authors initiated the current study to evaluate the efficacy and safety of RATS for thoracic neurogenic tumors. METHODS: This retrospective study is based on a prospectively created database that includes all RATS surgeries between 2018 and 2023. All patients with histologically confirmed neurogenic tumors were included in the study. The patients' medical and surgical records as well as radiological and pathological findings were analyzed. RESULTS: During a 5-year period, 27 patients underwent robotic resection of neurogenic tumors at a high-volume thoracic surgery center. Two patients had previously undergone posterior laminectomy for resection of the intraspinal components. The pathologies included schwannomas (18, 64%), ganglioneuromas (8, 29%), 1 paraganglioma, and 1 neurofibroma occurring close to a schwannoma unilaterally in the same patient. The median tumor size was 4.7 cm (range 0.9-11.4 cm). The median operating time was 69 minutes (range 27-169 minutes), and the median postoperative stay was 3 days (range 1-19 days). There was one conversion due to adhesions after a previous surgery. No major bleeding occurred. There was no perioperative mortality. Morbidity included a lymphatic fistula (n = 1), pneumonia (n = 1), prolonged air leak (n = 1), and 4 cases of postoperative pain persisting for more than 4 weeks. Neurological complications were mostly observed in patients with tumors located at the thoracic apex: 2 cases of Horner's syndrome, 2 cases with compensatory hyperhidrosis, 1 patient with paresis of the recurrent laryngeal nerve, and a T1 lesion resulting in a minor motor deficit of the small hand muscles (Medical Research Council grade 4) and hypoesthesia of the respective dermatome. CONCLUSIONS: RATS for thoracic neurogenic tumors is feasible and safe. Tumors at the thoracic apex are at high risk of neurological deficit and should be approached with care. Close interdisciplinary collaboration between neurosurgeons and thoracic surgeons is necessary for optimal patient selection and a good postoperative outcome.
RESUMEN
BACKGROUND: Balloon pulmonary angioplasty (BPA) is an emerging interventional treatment for inoperable chronic thromboembolic pulmonary hypertension (CTEPH) that targets subsegmental branches of the pulmonary artery. As the reported complication rates are high, the aim of the present study was to evaluate the effects of certain complications on the outcome after treatment. METHODS: From March 2014 to December 2019, a total of 235 patients with inoperable CTEPH underwent BPA. Of these patients, 140 were included who completed a follow-up examination 6 months after the last intervention; another 2 patients deceased due to complications of BPA. RESULTS: A high baseline pulmonary vascular resistance (PVR) >6.6 WU correlated with a higher rate of complications (mostly pulmonary artery perforations). Wire perforation during BPA did not correlate with worse outcome in terms of PVR reduction. The complication rate per intervention decreased from 21% to 14% during the 5 year period of the study. CONCLUSIONS: Complications are frequently observed in BPA, but the mortality rate is very low in expert centers. Importantly, the occurrence of complications does not portend a worse outcome.
