Forty-two patients complaining of constipation with abnormal anorectal motility were studied: 20 children and 6 adult females had a decreased rectoanal inhibitory reflex (RAIR) amplitude and 16 adult females had anal hypertonia and ultra slow waves (USW). Biofeedback training was used to condition the patients to relax the anal sphincter during the desire(More)
BACKGROUND Pyloric pressure and compliance have never been investigated in health nor gastroparesis. AIM We hypothesised that pyloric pressure and/or compliance may be altered in gastroparesis. METHODS Fasting pyloric pressure and compliance were investigated in 21 healthy volunteers (HV), 27 gastroparetic patients (GP) and 5 patients who had undergone(More)
The aim of this study was to determine whether the colonic motor profile of seven patients with constipation secondary to antidepressants differed from the motility of seven patients with idiopathic constipation and seven healthy volunteers. All constipated patients had very severe constipation. Colonic manometric recordings were performed for 24 h. The(More)
PURPOSE It has been suggested that the severity of fecal incontinence, the presence of pudendal neuropathy, or an external anal sphincter defect does not preclude clinical improvement with biofeedback therapy. A discrepancy, however, is frequently found between subjective improvement and objective results after biofeedback therapy. Our aim was to assess(More)
BACKGROUND The purpose of this study was to compare the manometric assessment of straining effort as if to defecate and rectoanal inhibitory reflex obtained with a rectosphincteric balloon probe and with a water-perfused catheter in the same subject. METHODS Twelve healthy volunteers underwent two manometric assessments of anal sphincter function and(More)
Six patients with complete transection of the spinal cord and six healthy volunteers were examined by using anorectal manometry together with electromyographic (EMG) recording of the external anal sphincter composed of striated muscle. Anal pressure and EMG activity of the external anal sphincter were continuously recorded at rest and during gradual rectal(More)
OBJECTIVE To determine (1) whether patients complaining of straining at stool have pelvic floor descent and anal abnormalities similar to those of patients with anal incontinence and (2) whether these patients are prone to develop anal incontinence. METHODS To answer the first question we used defecography to study perineal floor position at rest, during(More)
The aim of this work was to analyze clinical symptoms in light of anorectal manometry results. We compared the frequency of clinical symptoms in relation with the presence or absence of functional anomalies. Using this methodology, the following relationships may be suggested: the need to wear a pad, with a decreased resting pressure at the upper part of(More)
Two patients with acute colectasia, and acute urinary retention following pregnancy (case n. 1) and Klebsiellae septicemia (case n. 2) requiring endoscopic exsufflation in both cases, were seen. At onset, both patients had esophageal and anorectal manometric abnormalities with right colonic transit delay, and in case n. 2 urodynamic perturbation. Several(More)
The aim of this study was to assess (a) the incidence of perineal descent and (b) the relationship between radiological abnormalities of the pelvic floor and rectoanal manometric disturbances in patients consulting for constipation. Lateral radiographs in both the left lateral and supine positions studied pelvic floor descent. Results obtained in the 25(More)
