Evolution of lipid profiles after bariatric surgery.

Background: The most commonly encountered dyslipidemia in obese individuals is characterized by a cluster of interrelated plasma lipid and lipoprotein abnormalities including hypertriglyceridemia, low HDL cholesterol values, and increased small, dense LDL cholesterol particles. The aim of this study was to assess the changes in lipid profiles at baseline (pre-operatively) and at follow-up (6, 12, and 18 months) after a laparoscopic Roux-en-Y gastric bypass (LRYGBP). A retrospective observational study was performed involving all patients who consecutively underwent a LRYGBP between January 1, 2007 and December 31, 2009.

[Laparoscopic biopsy of non-digestive intra-abdominal masses].

Introduction: Laparoscopic surgery offers an alternative diagnostic technique in multiple diseases requiring biopsy of non-digestive intra-abdominal masses in which image-guided biopsy cannot be performed. Laparoscopic biopsy aims to reduce the surgical aggression and complications associated with laparotomy and favors the early treatment of malignancies.

Patients And Method: We performed a retrospective descriptive study of our results in a series of patients in our hospital with intra-abdominal masses of unknown etiology who underwent laparoscopic surgery between January 2001 and April 2006.
