Effect of abdominoplasty in the lipid profile of patients with dyslipidemia.

Introduction. Dyslipidemia like other chronic degenerative diseases is pandemic in Latin America and around the world. A lot of patients asking for body contouring surgery can be sick without knowing it. Objective. Observe the lipid profile of patients with dyslipidemia, before and three months after an abdominoplasty. Methods. Patients candidate to an abdominoplasty without morbid obesity were followed before and three months after the surgery. We compared the lipid profile, glucose, insulin, and HOMA (cardiovascular risk marker) before and three months after the surgery. We used Student's t test to compare the results. A P value less than 0.05 was considered as significant. Results. Twenty-six patients were observed before and after the surgery. At the third month, we found only statistical differences in LDL and triglyceride values (P 0.04 and P 0.03). The rest of metabolic values did not reach statistical significance. Conclusion. In this group of patients with dyslipidemia, at the third month, only LDL and triglyceride values reached statistical significances. There is no significant change in glucose, insulin, HOMA, cholesterol, VLDL, or HDL.

[Clinical research X. Usefulness of an organic mesh in the repair of abdominal defects]. / Reparación del defecto herniario. Empleo de malla de material orgánico.

OBJECTIVE: to measure the compliance, security and usefulness of organic mesh (bovine pericardium) in the repair of abdominal defect in an animal model. METHODS: Wistar rats (weight 300 to 500 g), were anesthetized and an abdominal defect of 1 cm in each animal was performed. Animals were divided according to the repair material used: bovine pericardium mesh (n = 6) and polipropilene mesh (n = 6). Animals were sacrificed on day 28 after the surgery. Presence of infection, necrosis and adherences (macroscopic and microscopic) were compared. Tensile force was also measured in both groups. RESULTS: inflammation, necrosis and adherences were similar in both groups. The prolene mesh (mean rupture force 66.5 joules) was stronger than bovine pericardium (mean rupture force 47.4 joules) p = 0.002, however, had also more adherences. CONCLUSIONS: there is no difference between inflammation, necrosis and adherences. But the polipropilene mesh was stronger than the bovine pericardium mesh. This finding could have relevance in the clinical practice (hernia recurrence).
