13 ESOPHAGEAL MOTILITY TESTING Occasionally endoscopy and barium esophagogram reports contain information about esophageal motility. Still, esophageal manometry is considered the gold standard in evaluating and quantifying esophageal motility. Esophageal manometry in patients with GERD is recommended to investigate the presence of esophageal motility abnormalities associated with GERD and to lo...

Understanding of the control mechanisms underlying gastric motor function is still limited. The aim of the present study was to evaluate antral pressure-geometry relationships during gastric emptying slowed by intraduodenal nutrient infusion and enhanced by erythromycin. In seven healthy subjects, antral contractile activity was assessed by combined dynamic magnetic resonance imaging and antrod...

The colon serves to absorb fluid and electrolytes, to mix its contents, to store its contents and to empty it in a controlled fashion. Motility, absorption and secretion closely interact to fulfil these functions. Tone, phasic contractions and ano-rectal closure are the main principles of colonic motility. They are controlled by the enteric nervous system. Colonic motility differs from that in ...

BACKGROUND Esophageal achalasia is the most common primary esophageal motor disorder. Laparoscopic Heller's myotomy combined with fundoplication represents the treatment of choice for this disease, achieving good results in about 90% of patients. However, about 10% of treated patients refer persistent or recurrent dysphagia. Many Authors showed that this failure rate is related to inadequate my...

Background/Aims Chronic intestinal pseudo-obstruction (CIPO) is a rare syndrome characterized by a failure of the propulsion of intraluminal contents and recurrent symptoms of partial bowel obstruction in the absence of mechanical obstruction. Regional variations of the intestinal compromise have been described. Intestinal manometry can indicate the pathophysiology and prognosis. Our objective ...

Tests of gastric, small intestinal and colonic motor function provide relevant physiological information and are useful for diagnosing and guiding the management of dysmotilities. Intraluminal pressure measurements may include concurrent measurements of transit or intraluminal pH. A consensus statement was developed and based on reports in the literature, experience of the authors, and discussi...

CONTEXT Anismus is a prevalent functional cause of outlet delay. It is characterized by symptoms of obstructed defecation associated with paradoxical contraction of the pelvic floor muscles. OBJECTIVE To evaluate the ability of two dimensional anal ultrasonography to identify anismus patients with paradoxical contraction or normal relaxation, comparing findings with manometric measurements. ...

BACKGROUND Anal canal dilatation and sphincterotomy have been recommended besides hemorrhoidectomy to overcome the anal pressures in the management of hemorrhoids. The aim of this study to compare internal sphincterotomy and hemorrhoidectomy with hemorrhoidectomy alone with respect to manometric and clinical measures. METHODS One hundred twenty patients with hemorrhoids were randomly assigned...
