RESUMEN
Smooth muscle is a normal component of the inferior vena cava (IVC) wall. Although uncommon, the smooth muscle component may undergo neoplastic change. Benign neoplasms are termed leiomyomas, and when there is a malignant change, the nomenclature is changed to an IVC leiomyosarcoma. Leiomyosarcomas of the IVC are rare, with less than 150 cases reported in medical literature. Unfortunately, the majority of IVC leiomyosarcomas are diagnosed at advanced disease stages. Surgical resection of locally advanced lesions is technically challenging, but complete resection is the mainstay of treatment as leiomyosarcomas respond poorly to chemo-radiotherapy. Due to the advanced disease stage at diagnosis and the technical complexity of IVC resection and reconstruction, most patients are transferred to high-volume centers in developed nations. We report a case of a patient with a locally advanced leiomyosarcoma masquerading as a pancreatic head tumor. This patient could not access care in a high-volume center and required aggressive maneuvers to resect the IVC leiomyosarcoma in a resource-poor, low-volume center. We present this case to highlight the steps in operative management and also to show that these procedures can be carried out in resource-poor environments once there is meticulous planning, appropriate equipment, and multidisciplinary care.
RESUMEN
OBJECTIVE: Issues concerning the training and certification of surgical specialists have taken on great significance in the last decade. A realistic computer-assisted, tissue-based simulator developed for use in the training of cardiac surgical residents in the conduct of a variety of cardiac surgical procedures in a low-volume cardiothoracic surgery unit of a typical developing country is described. The simulator can also be used to demonstrate the function of technology specific to cardiac surgical procedures in a way that previously has only been possible via the conduct of a procedure on a live animal or human being. METHODS: A porcine heart in a novel simulated operating theatre environment with real-time simulated haemodynamic monitoring and coronary blood flow, in arrested and beating-heart modes, is used as a training tool for surgical residents. RESULTS: Standard and beating-heart coronary arterial bypass, aortic valve replacement, aortic homograft replacement and pulmonary autograft procedures can be simulated with high degrees of realism and with the superimposition of adverse clinical scenarios requiring valid decision making and clinical judgments to be made by the trainees. CONCLUSIONS: The cardiac surgical simulation preparation described here would appear to be able to contribute positively to the training of residents in low-volume centres, as well as having the potential for application in other settings as a training tool or clinical skills assessment or accreditation device. Collaboration with larger centres is recommended in order to accurately assess the utility of this preparation as an adjunctive cardiothoracic surgical training aid.

Thoracic endometriosis syndrome (TES) is a rare presentation of systemic endometriosis. An unusual cluster of patients from the Caribbean who were treated at a single hospital during the year 2001 is presented. All patients were managed surgically in the acute phase, with satisfactory results. The etiology and management of TES has been controversial. A therapeutic approach that includes aggressive surgery to obliterate the pleural space combined with a course of hormonal suppression offers the best chance of cure for these patients.
