[Unique massive recurrence liposarcoma of the retroperitoneum].

Liposarcoma constitutes a heterogeneous group of tumors which rarely arise from the retroperitoneal area. They are the single most common tumor in all sarcoma of the retroperitoneum space. Surgery plays a dominant role in the treatment of retroperitoneal liposarcoma.

[Metastasis to brain from rectal cancer as the first manifestation of neoplasmatic disease].

Cerebral metastases from colorectal cancer are uncommon. They are usually a late manifestation of the neoplasmatic disease. The symptoms aren't always typical.

Rheological properties of erythrocytes in patients suffering from morbid obesity. Examination with LORCA device.

Unlabelled: Obesity is associated with many comorbid pathologies that lead to increased morbidity and increased mortality. Hemorheological changes in obesity are currently investigated as one of the risk factors for many comorbid pathologies. It has been found that erythrocyte hyperaggregation and a decrease in erythrocyte filterability have also been well documented in obesity patients.

Intra-abdominal abscess in the course of intragastric migration of an adjustable gastric band: a potentially life-threatening complication.

Intragastric band migration is a potential complication of adjustable gastric banding. A 39-year-old morbidly obese female underwent laparoscopic adjustable gastric banding. After uneventful postoperative follow-up of 4 years, she had slow, steady failure of the restrictive effect, associated with regain of weight.

Results of revisional operation following vertical banded gastroplasty performed due to morbid obesity--comparison between restoration of vertical banded gastroplasty and conversion of gastric bypass up to three years.

The aim of this study was to analyse incidence and efficacy of revisional surgery for failed vertical banded gastroplasty among 458 patients who underwent primary surgery between 1993 and 2003. Staple line disruption was diagnosed in 29 patients and was an indication for restoration of gastroplasty in 10 cases and a conversion to Roux-en-Y gastric bypass in 19 patients. In two cases of outlet stenosis the band was exchanged to enlarge the collar.
