Mediastinal Liposarcoma With Anterior and Posterior Mediastinal Involvement: A Thoracic Oncovascular Case Report.

A 64-year-old patient presented with shortness of breath and chest pressure. The initial examination was unremarkable, and a chest X-ray revealed a large mediastinal mass. Computed tomography (CT) scan demonstrated a lobulated mediastinal mass involving the great vessels and mass effect on the trachea, esophagus, and heart. A CT-guided biopsy showed a monotonous, evenly spaced population of mature, normal-appearing adipocytes consistent with a well-differentiated lipoma-like liposarcoma/atypical lipomatous tumor. The patient underwent a median sternotomy with en bloc tumor resection without adjuvant chemoradiation. Three-year follow-up CT imaging shows no evidence of tumor recurrence.

Thoracoscopic esophageal mobilization during minimally invasive esophagectomy: a head-to-head comparison of prone versus decubitus positions.

BACKGROUND: Minimally invasive esophagectomy (MIE) is being performed at an increasing number of institutions. The thoracoscopic portion is generally performed in the left lateral decubitus position. Recently there has been increasing interest in esophageal mobilization in the prone position and the potential benefits of this technique with regard to operative time, surgeon ergonomics, and operative exposure. We sought to objectively compare thoracoscopic mobilization of the esophagus in the left lateral decubitus position versus the prone position and identify potential differences between the two techniques. METHODS: A retrospective review of a prospectively maintained esophagectomy database identified 44 patients undergoing MIE during a 20-month period (June 2005-February 2007). Of these, 32 patients underwent thoracoscopic esophageal mobilization with cervical esophagogastric anastomosis. Eleven cases were performed in the left lateral decubitus position and 21 performed in the prone position. RESULTS: The patients were comparable in age, tumor stage, and fraction undergoing neoadjuvant therapy. There was no statistically significant difference between decubitus position and prone position with regard to number of lymph nodes procured (14.6 versus 15.5, p = 0.69), complications (6/11 versus 10/21, p = 1.0), length of stay (9 versus 10 days, p = 1.0), or intraoperative blood loss (85 versus 65 cc, p = 0.14). Thoracoscopic operative times were significantly shorter in the prone group than the decubitus group (86 versus 123 min, p = 0.0001). CONCLUSIONS: Prone thoracoscopic esophageal mobilization appears to be equivalent to decubitus thoracoscopic esophageal mobilization with respect to blood loss, number of lymph nodes dissected, and complications, but with a significant reduction in thoracoscopic surgical time.

Cardiac herniation after right pneumonectomy: case report and review of the literature.

Cardiac herniation is a rare condition, which is often lethal in unrecognized cases. It is most commonly seen after pneumonectomy with associated pericardiotomy or pericardiectomy but has been reported in patients with iatrogenic, traumatic, and congenital pericardial defects. It is important that the radiologist be aware of this entity, as delay in diagnosis may be fatal. In this paper, we will discuss a case of cardiac herniation after right pneumonectomy and review the radiologic literature.

Peritoneal tuberculosis in a 15-month-old male: surgical diagnosis of an insidious disease.

BACKGROUND: Peritoneal involvement is a relatively rare complication of tuberculosis, accounting for approximately 3.3% of extrapulmonary disease in the United States. Clinical diagnosis relies on a preponderance of indirect evidence and is often delayed. We describe such a patient. METHODS: An otherwise healthy 15-month-old male presented with fever, abdominal distention, vague abdominal pains, and a few episodes of watery diarrhea. Standard laboratory and radiologic work-up was unrevealing, and after a prolonged hospitalization, caseating granulomas were identified at diagnostic laparotomy. RESULTS: Definitive treatment was further delayed pending culture results, and the patient's condition worsened until fulminant cardiovascular collapse led to his demise. CONCLUSIONS: Despite effective chemotherapeutic regimens, the overall mortality of tuberculous peritonitis may be as high as 51%. The diagnosis must be considered and empiric antituberculous treatment started early in the course of the disease, even if definitive diagnosis is still pending.
