A pilot study on disturbed gastric myoelectric activity in obstructed defecation syndrome.

Background: Electrogastrography (EGG) is a noninvasive technique for recording gastric myoelectric activity. The aim of this study was to measure and record gastric myoelectric activity in patients with obstructed defecation syndrome (ODS) and to compare their results with those of normal individuals.

Methods: Forty-two patients (22 male) with ODS and a mean age of 41.

Esophageal motility pattern and gastro-esophageal reflux in chronic obstructive pulmonary disease.

Background/aims: The association of esophageal motility and gastroesophageal reflux symptoms with respiratory symptoms is not well established in patients with chronic obstructive pulmonary disease (COPD). The aim of this work is to study the abnormalities of esophageal function in COPD patients and study its relation to smoking index, body mass index and indices of hyperinflation.

Methodology: This study included 40 male COPD patients and 10 healthy controls.

Pelvic floor dyssynergia: efficacy of biofeedback training.

Background And Study Aims: Paradoxical contraction of the pelvic floor during attempts to defaecate is described as pelvic floor dyssynergia (anismus). It is a behavioural disorder (no associated morphological or neurological abnormalities); consequently, biofeedback training has been recommended as a behavioural therapy for such a disorder. The aim of the present study was to evaluate long-term satisfaction of patients diagnosed with pelvic floor dyssynergia after biofeedback.

Acid and bile reflux in erosive reflux disease, non-erosive reflux disease and Barrett's esophagus.

Background/aims: Gastroesophageal reflux disease (GERD) may occur with acid, bile or in a mixed form. Endoscopic injury and mucosal metaplasia are a known sequlae to pathological GERD. The aim of the study was to determine the contribution of acid and duodenogastroesophageal reflux (DGER) to endoscopic severity in patients with GERD and Barrett's esophagus.

Bile reflux measurement and its contribution to the severity of reflux esophagitis.

Background/aims: Gastroesophageal reflux disease (GERD) may occur with acid, bile or in a mixed form. Endoscopic injury and mucosal metaplasia are a known sequelae to pathological GERD. The aim of the study was to determine the contribution of acid and duodenogastroesophageal reflux to endoscopic severity in patients with GERD and Barrett's esophagus (BE).

Hypertensive lower esophageal sphincter (HLES): prevalence,symptoms genesis and effect of pneumatic balloon dilatation.

Summary And Background Data: The Hypertensive lower esophageal sphincter (HLES) is an unusual primary motor disorder of the esophagus. The significance of this motility disorder is still questionable.

Objective: The objectives were: (a) identification of the prevalence of HLES in these patients, (b) identification of the common presenting symptoms of HLES, (c) study of the correlation of the symptoms with LESP and (d) study of the effectiveness of pneumatic balloon dilation in cases that fail to respond to medical treatment.
