ReviewDoes thoracic epidural anaesthesia constitute over-instrumentation in video- and robotic-assisted thoracoscopic lung parenchyma resections?
Effective and sustained perioperative analgesia in thoracic surgery and pulmonary resection is beneficial to patients by reducing both postoperative pulmonary complications and the incidence of chronic pain. In this review, the indication of thoracic epidural anaesthesia in video- (VATS) and robotic-assisted (RATS) thoracoscopy shall be critically objectified and presented in a differentiated way. ⋯ Since clear evidence-based recommendations for optimal postoperative analgesia are still lacking in VATS and RATS, there can be no universal recommendation that fits all centres and patients. In this context, thoracic epidural analgesia is the most effective analgesia procedure for perioperative pain control in VATS and RATS-assisted surgery for patients with pulmonary risk factors.

Inflammatory leiomyosarcoma (ILMS), defined as "a malignant neoplasm showing smooth muscle differentiation, a prominent inflammatory infiltrate, and near-haploidization", is a very rare soft tissue tumor with a generally favorable prognosis. The morphologic features of "histiocyte-rich rhabdomyoblastic tumor" (HRRMT) are similar to those of ILMS, although this lesion shows by definition a skeletal muscle phenotype. Recent gene expression profiling and immunohistochemical studies have also suggested that ILMS and HRRMT may be related. ⋯ H-caldesmon expression was absent in all cases, using the specific h-CD antibody. Karyotypic study (1 HRRMT) and genome-wide copy number analysis (7 HRRMT, OncoScan SNP assay), revealed near-haploidization in four cases, with subsequent genome doubling in one, an identical phenotype to that seen in ILMS. We propose reclassification of ILMS and HRRMT as "inflammatory rhabdomyoblastic tumor", a name which accurately describes the salient morphologic and immunohistochemical features of this distinctive tumor, as well as its intermediate (rarely metastasizing) clinical behavior.
