[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.

The comparison of scoring scales for liver biopsy assessment in morbidly obese patients undergoing bariatric surgery.

Background: Many scoring systems have been applied for the grading and staging of non-alcoholic fatty liver disease (NAFLD). There is no consensus according to semiquantitative scales for the assessment of steatosis, inflammatory grading, and fibrosis staging in NAFLD.

Methods: We analysed 24 consecutive patients who underwent bariatric surgery.

[Tracheal injury during transhiatal esophagectomy treated conservatively].

Damage of trachea or main bronchi occurs rarely during esophagectomy, but when it happens the prognosis is unfavorable. There are no unambiguous guidelines for treatment in such cases. It is considered, that the tracheal injury can be managed by primary closure.

[Obesity and surgery].

Obesity is a life-long, progressive, life-threatening, genetically related, costly, multifactorial disease manifested by excessive fat storage. It is often accompanied by multiple comorbidities including mainly hypertension, diabetes, hyperlipidemia, hypoventilation, obstructive sleep apnea, degenerative arthritis and psychosocial impairment which influence the patients quality of life and ultimately limit their life expectancy. Conservative treatment of morbid and extreme obesity including diet, physical activity, behaviour modifications or pharmacotherapy is not effective in achieving a medically significant long-term weight loss.

[Assessment of plasma lipid profile oxysterols and vitamin E concentration in morbidity obese patients with coexisting arterial hypertension and non-insulin dependent diabetes mellitus].

Morbid obesity (BMI > or = 40 kg/m2) is accompanied by lipid disturbances which may be involved in the increased incidence of arterial hypertension and non-insulin dependent diabetes mellitus. The aim of the study was to assess plasma concentrations of total cholesterol (TC), HDL-cholesterol, LDL-cholesterol, triglycerides (TG) and two parameters of oxidation stress--vitamin E and oxysterols, in morbidly obese patients with coexisting arterial hypertension and non-insulin dependent diabetes mellitus. Studies were performed in 37 morbidly obese patients divided into three groups: group I--without coexisting diseases, group II--with arterial hypertension, and group III--with arterial hypertension and non-insulin dependent diabetes mellitus.
