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)
Achalasia is the best characterized primary esophageal motility disorder of the esophagus and typically presents with absent peristalsis of the esophageal body and a failure of the lower esophageal sphincter to relax upon swallowing on manometry, associated with progressively severe dysphagia, regurgitation, aspiration, chest pain, and weight loss. The(More)
The mechanical properties of the esophagogastric junction (EGJ) are of major importance for the competence of the EGJ. Although manometry reliably measures sphincter pressure, no information is provided on distensibility, a crucial determinant of flow across the EGJ. Recently, a new technique, impedance planimetry, was introduced allowing accurate(More)
OBJECTIVE To gain insight into the role of consultation in palliative sedation. DESIGN Retrospective analysis. METHOD All consultation records of the Palliation Team Midden Nederland (PTMN) from 1 November 2005 to 31 October 2006 were analysed. If palliative sedation was mentioned in the record, the following variables were listed: character of the(More)
Achalasia is a rare motility disorder of the esophagus characterized by the absence of peristalsis and defective relaxation of the lower esophageal sphincter. Patients present at all ages with dysphagia and regurgitation as main symptoms. The diagnosis is suggested by barium swallow and endoscopy and confirmed by manometry. Because there is no curative(More)
and high-resolution manometric techniques, it is possible to examine the dynamic response of the LES in treated achalasia patients for longer intervals, particularly in response to bolus challenges. In my experience, one often finds that a low “resting” LES pressure can increase quite dramatically and obstructively in response to luminal distension of(More)
OPINION STATEMENT Achalasia is a primary esophageal motor disorder of the esophagus that is characterized by the absence of esophageal peristalsis and a failure of the lower esophageal sphincter (LES) to relax upon swallowing. The defective relaxation leads to symptoms of dysphagia for solids and liquids, regurgitation, aspiration, chest pain, and weight(More)
Consumers have high expectations about the audio and video quality delivered by media processing devices. Applications running on these media processing devices, like high quality multi-window television and MPEG-video decoders, require a computational performance in the order of 10-100 giga operations per second. Embedded systems are quickly evolving(More)
