Reversibility of Intrathoracic Lipotoxicity in Obesity After Bariatric Surgery

Reversibility of intrathoracic lipotoxicity in obesity after bariatric surgery: use of magnetic resonance imaging.

Intrathoracic lipotoxicity is the consequence of increased accumulation and biological activity of various fat deposits in obesity, more specifically epicardial (“fat around the heart”) and intramyocardial fat (“fat within the myocardium”). Epicardial fat is located in close proximity to the coronary arteries within the visceral pericardial layer (in contrast to the paracardial or mediastinal f...

Bariatric Surgery in Hypothalamic Obesity

Craniopharyngiomas (CP) are epithelial neoplasms generally found in the area of the pituitary and hypothalamus. Despite benign histology, these tumors and/or their treatment often result in significant, debilitating disorders of endocrine, neurological, behavioral, and metabolic systems. Severe obesity is observed in a high percentage of patients with CP resulting in significant comorbidities a...

Cholesterol Metabolism After Bariatric Surgery in Grade 3 Obesity

OBJECTIVE Malabsorptive bariatric surgery (biliopancreatic diversion and biliointestinal bypass [BIBP]) reduces serum cholesterol levels more than restrictive surgery (adjustable gastric banding [AGB]), and this is thought to be due to greater weight loss. Our aim was to evaluate the changes of cholesterol metabolism induced by malabsorptive and restrictive surgery independent of weight loss. ...

Delayed Intrathoracic Gastric Perforation After Obesity Surgery: A Severe Complication

We describe a case of a patient with an intrathoracic gastric perforation, 6 months after she underwent a gastric banding procedure for the treatment of morbid obesity. After an urgent laparotomy during which the stomach was replaced and oversewn, she recovered uneventfully. The possible mechanism of this severe complication is discussed.
