Ileal disease or resection causes bile salt malabsorption and a reduction in the bile salt content of bile. Since cholesterol solubility requires adequate bile salt concentrations, depletion of the bile salt content of bile might, therefore, jeopardize cholesterol solubility and predispose to cholesterol gallstone formation. To study this, we examined biliary lipid composition in 10 patients wi...

Background: The gold standard of the management of rectal cancer in the middle and lower parts is low anterior resection with coloanal anastomosis. About 50% of the patients undergoing this procedure might experience some complications because of the low capacity of the neorectum. The aim of this study was to evaluate ileal J-pouch interposition as a neorectum between the anal canal and the rem...

AIM To investigate quality of life (QoL) domains with three forms of urinary diversions, including ileal conduit, MAINZ pouch, and orthotopic ileal neobladder after radical cystectomy in men with muscle-invasive bladder cancer. MATERIALS AND METHODS In a prospective study, 149 men underwent radical cystectomy and urinary diversion (70 ileal conduit, 16 MAINZ pouch, and 63 orthotopic ileal neo...

Objective: To describe the surgical technique and initial experience of laparoscopic radical cystectomy and intracorporeal orthotopic ileal neobladder with bilateral isoperistaltic afferent limbs. Materials and Methods: From January 2014 to Jun 2015, 11 patients underwent a new method of orthotopic ileal neobladder intracorporeally after laparoscopic radical cystectomy at our institution. To co...

We examined for vesicular trafficking of the Na(+)/H(+) exchanger (NHE) in pH-stimulated ileal and CO(2)-stimulated colonic Na(+) absorption. Subapical vesicles in rat distal ileum were quantified by transmission electron microscopy at x27,500 magnification. Internalization of ileal apical membranes labeled with FITC-phytohemagglutinin was assessed using confocal microscopy, and pH-stimulated i...

The human intestinal tract harbors large bacterial community consisting of commensal, symbiotic, and pathogenic strains, which are constantly interacting with the intestinal immune system. This interaction elicits a non-pathological basal level of immune responses and contributes to shaping both the intestinal immune system and bacterial community. Recent studies on human microbiota are reveali...

We investigated the effects of somatostatin on the ileal movements after gravity stress and compared these effects between male and female rats. Using an in vitro preparation, measurements of ileal movements evoked by somatostatin application were done at 1, 3, 15 and 30 days after 3G gravity loading-conditioning. Mixed phasic and tonic patterns were observed in the ileal muscle activities. Gra...

Exstrophy of the urinary bladder is an uncommon congenital anormaly for wich cystectomy was recommended because of a high risk of developing carcinoma. We report a patient treated by cystectomy and ileal loop diversion, who, 34 years later, developed carcinoma of the ileal loop. It is the third report of a tumor developing in a ileal conduit constructed after cystectomy for bladder exstrophy.

BACKGROUND Reported negative ileal and total tract dietary fiber (DF) digestibility values are physiologically untenable and suggest the presence of nondietary material in the gut contents that interferes with the DF determination. OBJECTIVE The objective of this study was to demonstrate the importance of interfering material (IM) when the Prosky method was used to determine DF digestibility....

Using a triple-lumen constant perfusion system, the following observations were made in normal subjects. First, chloride, bicarbonate, and sodium were found to exhibit net movement across ileal mucosa against electrochemical gradients. Second, during perfusion with a balanced electrolyte solution simulating plasma, the ileum generally absorbed, but sometimes secreted fluid. A reciprocal net mov...
