Effect of the GLP-1 analog liraglutide on satiation and gastric sensorimotor function during nutrient-drink ingestion
2012
Background/Aim:Liraglutide, a glucagon-like peptide-1 analog, induces weight loss. We investigated whether liraglutide affects gastric accommodation and satiation by measuring the intragastric pressure (IGP) during nutrient-drink consumption and using the barostat technique.Methods:Ten healthy volunteers (HVs) were tested after placebo, 0.3, 0.6 or 1.2 mg liraglutide administration. IGP was studied during intragastric nutrient-drink (1.5 kcal ml(-1)) infusion (60 ml min(-1)), while the HVs scored their satiation on a graded scale until maximal satiation. In a separate session, isobaric distentions were performed using the barostat with stepwise increments of 2 mm Hg starting from minimal di…
Early Results of Fissurectomy and Advancement Flap for Resistant Chronic Anal Fissure without Hypertonia of the Internal Anal Sphincter
2010
The aim of this study was to assess the efficacy of fissurectomy with skin advancement flap in healing chronic anal fissures without hypertonia of the internal anal sphincter. Twenty-six consecutive patients who failed healing after well-practiced topical medical therapy were enrolled. Anorectal manometry was performed preoperative and 6 months postoperatively. All patients were treated with fissurectomy and advancement flap through healthy skin tissue. All patients healed completely within 30 days from operation. The intensity and the duration of pain post-defecation was reduced significantly with respect to the preoperative values starting from the first defecation. One patient suffered …
The prognostic value of mucociliary clearance in predicting success in tympanoplasty
1993
AbstractMucociliary and equipressive eustachian tube functions have been studied, using saccharin solution (five per cent sodium saccharinate) and tubal manometry respectively, in 58 ears with chronic disease undergoing tympanoplasty. The position of the perforation site determines the results as the poorest results are obtained from the posterior ones, positive cases (47 per cent) and mean transport time (37.7 minutes), compared to the greater percentage of positive cases (86 per cent) and mean transport time (22.2 minutes) for anterior perforations.When both parameters are analysed together there is a direct relationship between normal equipressive function and normal mucociliary transpor…
Esophageal abnormalities in morbidly obese adult patients.
2015
Abstract Background An increase in body mass index has been found to be associated with an increase in the prevalence of gastroesophageal reflux disease (GERD) symptoms, esophageal mucosal injury, and GERD complications. Few systematic studies with objective tests have evaluated esophageal disorders in the morbidly obese population. Objectives To define more precisely in morbidly obese people the incidence of esophageal symptoms and characterize the esophageal disorders using objective data. Setting University Hospital, Spain. Methods Two hundred twenty-four presurgical morbidly obese patients were submitted to a protocol including a clinical history and objective tests (endoscopy, stationa…
Fissurectomy combined with anoplasty and injection of botulinum toxin in treatment of anterior chronic anal fissure with hypertonia of internal anal …
2010
Abstract BACKGROUND: In patients affected by anterior chronic anal fissure (CAAF) with hypertonia of the internal anal sphincter (IAS), the role of IAS hypertonia remains unclear. The aim of this study was to evaluate the efficacy of fissurectomy combined with advancement flap and IAS injection of botulinum toxin in healing the CAAF with hypertonia of IAS resistant to medical therapy. METHODS: Ten consecutive patients were enrolled. Anorectal manometry was performed preoperatively and at 6 months. CAAF with hypertonia was defined as those associated with maximum resting pressure (MRP) values higher than 85 mmHg. All patients underwent fissurectomy and anoplasty with advancement skin flap co…
Improvement of wound healing after hemorrhoidectomy: a double-blind, randomized study of botulinum toxin injection.
2005
PURPOSE: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play in important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemaorrhoidectomy in reducing the maximum testing pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward ill all patients un…
Noninvasive peripheral vascular function and atrial fibrillation in the general population.
2019
Background Arterial stiffness is a strong predictor of atrial fibrillation in the community. Whether noninvasively measured conduit artery function and peripheral vascular reactivity are related to atrial fibrillation remains unknown. Methods and results In 15 010 individuals of the population-based Gutenberg Health Study, mean age 55 ± 11 years, 50.5% men, we determined noninvasive vascular function by flow-mediated dilation (FMD) and peripheral arterial tonometry (PAT) in relation to manifest atrial fibrillation (N = 466). Patients with atrial fibrillation exhibited a higher mean brachial artery diameter [4.81 mm (4.17, 5.33) in atrial fibrillation vs. 4.31 mm (3.67, 4.93)] and baseline p…
Esophageal dysfunction and its pathogenesis in progressive systemic sclerosis
1978
In 25 patients with progressive systemic sclerosis esophageal involvement was studied prospectively by analysing subjective symptoms and radiological and manometric criteria. In all patients abnormal motility could be demonstrated by X-ray and/or manometry: radiologically in 18 (72%), manometrically in 22 (88%) cases. Dysphagia was present only in 11 patients (44%). Six patients (24%) had no subjective symptoms in spite of severe objective esophageal abnormalities. Therefore, the absence of esophageal symptoms does not exclude advanced affliction of the esophagus. To determine the pathogenesis of esophageal dysfunction the effects of 3.5 microgram/kg carbachol and of 0.6 microgram/kg pentag…
Evaluation of esophagogastric junction relaxation by 4-second Integrated Relaxation Pressure in achalasia using High Resolution Manometry with water-…
2014
Background Relaxation of the esophagogastric junction (EGJ) is now evaluated calculating 4-second integrated relaxation pressure (4-s IRP) by high resolution manometry (HREPT). Solid-state catheters have been used to define abnormal values. Our aim was to evaluate 4-s IRP in esophageal achalasia using HREPT with perfused catheters. Methods From June 2009 to June 2013, 936 HREPT studies have been performed in our unit. Of these, 194 patients having treated achalasia were excluded. Control group was constituted by 695 patients without achalasia, and 47 patients with untreated achalasia constituted the study group. HREPT was performed with water-perfused catheters. To establish the cut-off val…
A functional study of the esophagus in patients with non-cardiac chest pain and dysphagia.
2015
Background/Aims: Nutcracker esophagus and non-specific motility disorders are the main causes of non-cardiac chest pain (NCCP), with gastroesophageal reflux in 60% of cases. Achalasia and diffuse esophageal spasm are the most frequent anomalies described in patients with dysphagia. The goal of this study was to evaluate the occurrence of esophageal body and lower esophageal sphincter motor abnormalities in patients with dysphagia, NCCP, or both. Materials and Methods: This study is a retrospective analysis of 716 patients with NCCP and/or dysphagia tested between January 1994 and December 2010. 1023 functional studies were performed, 707 of which were esophageal manometries, 225 esophageal …
