[Gastric pacing to treat morbid obesity: two years experience in four patients].

Background: Gastric pacing to treat morbid obesity has been found to be safe and the implant technique simple to perform. Appetite is reduced and satiety is increased after the implant. There are two components in the Implantable Gastric Stimulation (IGS): (a) an electrical stimulator connected to a (b) bipolar lead that is positioned in the muscle wall of the stomach.

[The biliointestinal bypass: a thirty-years experience].

Aim: Aim of our study was the evaluation of Italian experience with bilio-intestinal bypass in the surgical treatment of morbid obesity.

Materials And Methods: 1030 patients; mean age 36.1 years; preoperative mean weight Kg 136.

TEQ(S) and body burden for PCDDs, PCDFs, and dioxin-like PCBs in human adipose tissue.

Polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), mono-ortho and non-ortho polychlorinated biphenyls (dioxin-like PCBs) were determined in samples of human fat tissue from nine Italian obese patients. The toxicity equivalent (TEQ) values ranged from 9 to 25 pg TEQ g(-1) lipid (WHO-TEF values, 2005 [Van den Berg, M., Birnbaum, L.

[Technical options in bariatric surgery and their mechanisms of action].

In recent years, bariatric surgery has enjoyed a high level of approval. There are several technical and surgical options. Most of the departments of obesity surgery perform usually the same procedure, when just in a few center the procedure can be adapted depending on the patient need.

Comparison of changes in lipid profile after bilio-intestinal bypass and gastric banding in patients with morbid obesity.

Background: The presence of hypercholesterolemia is currently not considered a selection criteria for performing gastric restrictive or diversionary bariatric surgery.

Methods: We prospectively investigated the effects of the bilio-intestinal bypass (BI-bypass) with a wide cholecysto-jejunal anastomosis and of adjustable gastric banding (AGB) on blood lipid concentrations in obese patients. To clarify the mechanism of the hypocholesterolemic effect of the BI-bypass, daily fecal sterol excretion was measured by gas-liquid chromatography (GLC).
