Long-Term Results of Radiofrequency Energy Delivery for the Treatment of GERD: Results of a Prospective 48-Month Study.

Since 2000, radiofrequency (RF) energy treatment has been increasingly offered as an alternative option to invasive surgical procedures for selected patients with gastroesophageal reflux disease (GERD). Out of 69 patients treated since June 2002 to December 2007 with the Stretta procedure, 56 of them reached by the end of 2010 a 48-month followup. RF treatment significantly improved heartburn scores, GERD-specific quality of life scores, and general quality of life scores at 24 and 48 months in 52 out of 56 patients (92,8%).

Education improves colonoscopy appropriateness.

Background: Appropriateness in GI endoscopy is critical to face the rising amount of demands. Education of physicians has been advocated to reduce the level of inappropriateness.

Objective: Our purpose was to assess the effectiveness of an educational program in determining a reduction of inappropriate colonoscopies in an open access system.

Effects of symbiotic preparations on constipated irritable bowel syndrome symptoms.

Background: Prebiotic and probiotic therapies are new strategies that are being used to treat different gastrointestinal diseases, such as irritable bowel syndrome, diverticular disease and inflammatory bowel diseases.

Aims: Evaluating the effects of a symbiotic preparation on symptoms and colonic transit in patients with irritable bowel syndrome and significant bloating.

Methods: We carried out an open-label, prospective, uncontrolled, multicenter trial on 129 patients meeting Rome II criteria for irritable bowel syndrome who did not have lactose malabsorption, abdominal surgery, overt psychiatric disorders and ongoing psychotropic drug therapy or ethanol abuse.

Appropriateness of colonoscopy: diagnostic yield and safety in guidelines.

Aim: To evaluate if the guidelines for the appropriateness of performing colonoscopy by American Society for Gastrointestinal Endoscopy (AGSE) and Italian Society of Digestive Endoscopy (SIED) yield a good diagnostic efficacy and do not present risks of missing important colonic pathologies in an Italian population sample.

Methods: A total of 1017 consecutive patients (560 men and 457 women; mean age 64.4 +/- 16 years) referred to an open-access endoscopy unit for colonoscopy from July 2004 to May 2006 were evaluated according to ASGE and SIED guidelines for appropriateness of performing the procedure.

Decreased expression of stem cell factor in esophageal and gastric mucosa after esophagogastric anastomosis for cancer: potential relevance to motility.

Background: Esophageal replacement with gastric tube is a well-established reconstruction of the alimentary tract after esophagectomy in cancer patients. The resulting molecular events in the transposed gastric tube and residual esophagus have yet to be investigated. Stem cell factor (SCF) was recently shown to be critical for signaling in gastrointestinal motility.

Human leukocyte interferon-alpha treatment for chronic HCV-related hepatitis in hemophilic patients previously intolerant to other interferons-alpha.

Thirty patients affected by hemophilia A or B or von-Willebrand's disease and chronic posttransfusional active HCV hepatitis who developed major side effects during the course of a previous treatment with recombinant interferon-alpha (IFN-alpha) were studied. In all patients IFN-alpha therapy had to be discontinued and those who achieved a primary serologic and viral response to HCV relapsed within a few months. After a washout period, patients were retreated with human leukocyte IFN-alpha, 6 MU thrice weekly for 12 months.
