BACKGROUND AND STUDY AIMS : Endoscopic techniques have demonstrated their effectiveness in metabolic surgery, notably through a gastrointestinal (GI) liner, with a less invasive approach than conventional surgery. Our study evaluates the safety and efficacy of endoscopic GI anastomosis (EGIA) using a lumen-apposing stent to secure the anastomosis. MATERIALS(More)
Uterine arteries from pregnant and nonpregnant patients were studied to define their responses to lidocaine. Although local anesthetics usually are considered vasodilators, these data indicate that the human uterine artery constricts when exposed to 1,000 mug of lidocaine in vitro. Furthermore, those arteries from pregnant patients exhibited significantly(More)
Tubular aggregates (TAs) are aggregates of densely packed tubules in human skeletal muscle fibers with particular histochemical and ultrastructural features that most probably arise from the sarcoplasmic reticulum. Some studies have shown an additional mitochondrial origin of TAs. We studied the histopathological spectrum and clinical features in a large(More)
Nine uterine artery segments were obtained during Caesarean hysterotomy. The amount of isometric tension developed by each segment when exposed to 3, 6, 10, 20, 50, 100, 1000 and 2000 microng/ml of lignocaine hydrochloride (Xylocaine) was measured. All nine segments contracted in response to the 1000- and 2000-microng/ml concentrations. Eight of nine, six(More)
