Establishing the etiology of a retroperitoneal tumor may be difficult due to close proximity of multiple organs. Evaluation of retroperitoneal tumors often leads to surgery, many times to obtain a definitive diagnosis and rule out malignancy. Calcifying fibrous tumors (CFT) are very rare soft tissue tumors occurring most often in young patients. They are most often found arising in the thoracic...

IntroductionThe optimal extent of lymphadenectomy during esophagectomy remains unclear. In this trial, we aim to clarify whether three-field (cervical-thoracic-abdominal) improved patient survival over two-field (thoracic-abdominal) for esophageal cancer.MethodsBetween March 2013 and November 2016, a total 400 patients with middle lower thoracic cancer were included randomly assigned undergo ei...

Perivascular adipose tissue (PVAT) is implicated as a source of proatherogenic cytokines. Phenotypic differences in local PVAT depots may contribute to differences in disease susceptibility among arteries and even regions within an artery. It has been proposed that PVAT around the abdominal and thoracic aorta shares characteristics of white and brown adipose tissue (BAT), respectively; however,...

PURPOSE To investigate if tests used in the preoperative period of upper abdominal or thoracic surgeries are able to differentiate the patients that presented cardiopulmonary postoperative complications. METHODS Seventy eight patients, 30 submitted to upper abdominal surgery and 48 to thoracic surgery were evaluated. Spirometry, respirometry, manovacuometry, six-minute walk test and stair-cli...

Thoracic disk herniation comprises 0.15% of all disk herniation and has various and confusing manifestations.  Among them, radicular pain down the leg could be the rarest presentation, especially if it is the only complaint. On the other hand, finding the relationship between clinical and paraclinical needs require high index of suspension and it is demanding. A 34-year-old patient, who ha...

paragangliomas are tumors that originate from extra-adrenal medullary neural crest derivatives. they are rarely located in retroperitoneal space. these tumors are often discovered incidentally during imaging studies performed for other reasons.periampullary cancers include adenocarcinomas arising from the pancreas, ampulla of vater, duodenum or distal common bile duct. the exact site of origin ...

CONTEXT AND OBJECTIVE Studies have shown that physiopathological changes to the respiratory system can occur following thoracic and abdominal surgery. Laminectomy is considered to be a peripheral surgical procedure, but it is possible that thoracic spinal surgery exerts a greater influence on lung function. The aim of this study was to evaluate the pulmonary volumes and maximum respiratory pres...
