BACKGROUND The presence of Lewy bodies and Lewy neurites (LN) has been demonstrated in the enteric nervous system (ENS) of Parkinson's disease (PD) patients. The aims of the present research were to use routine colonoscopy biopsies (1) to analyze, in depth, enteric pathology throughout the colonic submucosal plexus (SMP), and (2) to correlate the(More)
BACKGROUND The treatment of gastroparesis remains unsatisfactory despite prokinetic and anti-emetic drugs. Gastric electrical stimulation has been proposed as a therapeutic option. We have assessed the effect of gastric electrical stimulation on symptoms, medical treatment, body weight and gastric emptying in patients with intractable symptomatic(More)
BACKGROUND & AIMS Some carbohydrates escape small intestinal absorption, and their presence in the ileum can affect proximal gut motility. Carbohydrates reaching the colon can inhibit gastric and pancreatic secretions. The hypothesis of this study was that colonic fermentation products of carbohydrates (short-chain fatty acids [SCFAs]) affect proximal gut(More)
BACKGROUND & AIMS Patients with achalasia are treated with either pneumatic dilation (PD) or laparoscopic Heller myotomy (LHM), which have comparable rates of success. We evaluated whether manometric subtype was associated with response to treatment in a large population of patients treated with either PD or LHM (the European achalasia trial). METHODS(More)
Several studies, using pH monitoring with event markers, have identified patients with normal oesophageal exposure to acid despite an apparent relation between symptoms and reflux episodes. In this series of 771 consecutive patients referred for 24 hour oesophageal pH monitoring, a probability calculation was used to evaluate the relation between symptoms(More)
BACKGROUND Until recently only two therapeutic options have been available to control symptoms and the esophagitis in chronic gastro-oesophageal reflux disease (GERD), i.e. lifelong proton pump inhibitor (PPI) therapy or anti-reflux surgery. Lately, transoral incisionless fundoplication (TIF) has been developed and found to offer a therapeutic alternative(More)
CONTEXT Gastro-oesophageal reflux disease (GORD) is a common chronic disorder that has severe impact on quality of life and often requires continuous acid-suppression therapy. Proton-pump inhibitors (PPIs) are extremely effective but expensive, and do not restore the normal antireflux barrier at the gastro-oesophageal junction. Antireflux surgery, even with(More)
BACKGROUND Respiratory manifestations represent one of the most prevalent and difficult-to-manage extra-oesophageal syndromes of gastro-oesophageal reflux disease. AIMS To review the epidemiology, pathophysiological mechanisms and therapeutic outcomes of reflux-related respiratory disorders. METHODS Search of the literature published in English using(More)
BACKGROUND To evaluate the safety and clinical efficacy of botulinum toxin (BT) in patients with achalasia followed up for six months. METHODS Fifty five symptomatic patients with manometrically proven achalasia were included in a multicentre prospective trial. Before and two weeks and two months after intrasphincteric injection of BT, symptoms of(More)
OBJECTIVE Achalasia is a chronic motility disorder of the oesophagus for which laparoscopic Heller myotomy (LHM) and endoscopic pneumodilation (PD) are the most commonly used treatments. However, prospective data comparing their long-term efficacy is lacking. DESIGN 201 newly diagnosed patients with achalasia were randomly assigned to PD (n=96) or LHM(More)
