PURPOSE This study evaluated the long-term (5-year) durability of radiofrequency energy delivery for fecal incontinence. METHODS This was an extension of the follow-up from our original prospective study in which patients who suffered from fecal incontinence were treated with the SECCA system for radiofrequency energy delivery to the anal canal muscle.(More)
PURPOSE This study evaluated the durability and long-term safety of radio-frequency energy delivery for fecal incontinence (Secca procedure). METHODS This was an extended follow-up of a prospective study in which patients with fecal incontinence of various causes underwent radio-frequency energy delivery to the anal canal muscle. The Cleveland Clinic(More)
PURPOSE In this prospective study we investigated the feasibility, safety, and efficacy of radio-frequency energy delivery deep to the mucosa of the anal canal for the treatment of fecal incontinence. METHODS We studied ten patients with fecal incontinence of varying causes. All patients underwent anoscopy, anorectal manometry, endorectal ultrasound, and(More)
Our aim was to characterize the clinical spectrum of anorectal dysfunction among eight patients with progressive systemic sclerosis (PSS) who presented with altered bowel movements with or without fecal incontinence. The anorectum was assessed by physical examination, proctosigmoidoscopy, and anorectal manometry. There was concomitant involvement of the(More)
The accuracy of the 14C-D-xylose breath test in the diagnosis of small-bowel bacterial overgrowth was prospectively evaluated in 10 patients with motility disorders: 6 myopathic, 3 neuropathic, and 1 mechanical obstruction. Six of the 10 patients had small-bowel bacterial overgrowth (> or = 10(5) colony-forming units/ml) on culture of small-bowel aspirate.(More)
BACKGROUND The traditional system for esophageal 24-h pH monitoring requires transnasal introduction of the catheter with pH sensors; this technique produces discomfort, inconvenience, and interference with daily activity. Recently, a catheter-free pH monitoring system (Bravo) has been proposed as an alternative and promising method for 24-h pH. AIM To(More)
Multiple lymphomatous polyposis (MLP) is an uncommon type of primary non-Hodgkin gastrointestinal (GI) B-cell lymphoma characterized by the presence of multiple polyps along the GI tract. Malignant cells of MLP have mantle cell characteristics and thus are considered to be the counterpart of the mantle cell lymphoma (MCL) in the GI tract. Since 1961, no(More)
BACKGROUND Post-infectious irritable bowel syndrome (PI-IBS) prevalence, small intestinal bacterial overgrowth (SIBO), altered microbiota, low-grade inflammation, and antibiotic therapy in IBS are all controversial issues. AIMS To conduct an evidence-based review of these factors. METHODS A review of the literature was carried out up to July 2012, with(More)
BACKGROUND In the last decades it has been suggested that the main cause of liver cirrhosis in Mexico is alcohol. Currently in Western countries hepatitis C virus stage liver disease and liver transplantation. In Mexico, we have no data relative to the etiology of liver cirrhosis. The aim of this study was to investigate the main causes of liver cirrhosis(More)
The current review includes all the available original data on irritable bowel syndrome in Mexico. Data were organized in items of interest such as prevalence and gender distribution, health care utilization, psychosocial factors, diagnostic criteria, bowel habit predominance, physiological studies, clinical trials and quality of life assessment.
