Analysis of potential risk factors in the survival of patients with primary retroperitoneal liposarcoma.

Introduction: The present work is an observational study of a series of variables regarding overall survival and disease-free survival in patients diagnosed with primary liposarcoma.

Methods: The study is prospective with retrolective data collection that includes all patients with primary liposarcoma referred to Hospital Son Espases University Hospital, Palma de Mallorca, Spain from January 1990 to December 2019.

Results: The study includes 50 patients and the compartment surgery was performed in 18 patients (36%) of cases.

Giant mesenteric fibromatosis associated with non-Hodgkin lymphoma. A case report and literature review.

Background: Mesenteric fibromatosis is a benign locally-aggressive mesenchymal neoplasm that lacks the potential for metastasis. It is related to Gardner's Syndrome, previous trauma, abdominal surgery, and prolonged intake of oestrogen. Differentially diagnosing this from similar tumours is crucial in order for establishing the appropriate treatment and only immunohistochemical features can be used for a definitive diagnosis.

Biliopancreatic Diversion in the Surgical Treatment of Morbid Obesity: Long-Term Results and Metabolic Consequences.

Purpose: In the multidisciplinary therapeutic approach to obesity, bariatric surgery is considered the most effective treatment in weight reduction and the decrease in associated comorbidities. The objective of this work is to describe the long-term clinical and metabolic results in obese patients undergoing biliopancreatic diversion (BPD) according to Scopinaro's technique.

Materials And Methods: Patients undergoing surgery were followed by the same multidisciplinary team in a study period of 15 years (1999-2015).

Effect of rofecoxib on colon chemical carcinogenesis at colonic anastomotic area in the rat.

Aim: To investigate the effect of the selective cyclooxygenase-2 (COX-2) inhibitor rofecoxib on the incidence of perianastomotic colonic tumors in a model of chemical carcinogenesis in the rat.

Experimental Design: Experimental study with 45 male Sprague-Dawley rats randomly assigned to one of three groups: control (n = 15) with colocolic anastomosis and chemical carcinogenesis with 1-2 dimethylhydrazine (1-2 DMH); rofecoxib 0.0027% (n = 15) with colonic anastomosis, chemical carcinogenesis and the addition of dietary rofecoxib at doses of 27 parts per million (ppm), and rofecoxib 0.
