Electrophysiological analysis of the interaction between the lateral septum and the central nucleus of the amygdala.

Evidence suggests that the lateral septum (LS) and the central nucleus of the amygdala (CeA) play opposing roles in the modulation of fear and anxiety. The current study examined the interaction of the two structures in the albino rat by electrically stimulating each and recording single-unit activity in the other. In each case, electrical stimulation consisted of 50 trains of 5 pulses 800μA in amplitude, 0.

Using the StomaphyX(TM) endoplicator to treat a gastric bypass complication.

Background And Objectives: As the number of bariatric operations performed increases, the number of patients requiring reoperation for failed weight loss is expected to proportionately increase. Natural orifice surgery is an alternative approach to revisional gastric bypass surgery when postoperative complications, such as dilatation of the gastrojejunostomy, gastrogastric fistula, and gastric pouch, dilation occur.

Methods: The present article reports on the safe and successful use of an endoscopic tissue plicating device in a patient found to have a dilated gastric pouch and a gastrogastric fistula 12 years after an open, nondivided RYGB.
