[Infiltrating intramuscular lipoma].

Intramuscular lipomas are rare, benign unencapsulated tumors. They are also called infiltrating lipomas because of their infiltrative growth pattern which, deeply localized, seizes the skeleton muscle. The only obvious symptom is a palpable mass.

[Endotube insertion for palliation of esophageal and cardia cancer: experiences with a new endoprosthesis].

Therapy of inoperable carcinoma of the esophagus and cardia must be based on correction of the dysphagia. On that purpose, a new endoprosthesis (type ESKA-Buess) was used. 57 patients were treated by endoscopic placement of an endoprosthesis.

[Leg-/pelvic vein thrombosis from the viewpoint of the surgeon].

The pathogenesis of venous thrombosis is far less clear than that of arterial thrombosis. In spite of physical and medical prophylaxis, there is still a risk of thrombosis of approx. 5% left after elective abdominal surgery.

A modified prosthesis for the treatment of malignant esophagotracheal fistula.

Esophagotracheal fistula is usually a sequela of irradiation or laser treatment of advanced carcinoma of the esophagus or the tracheobronchial tree. Resection of the tumor in these cases is not possible, and palliative bypass surgery is highly risky. The peroral placement of a prosthesis is less invasive, but conventional prostheses often fail to occlude the fistula.
