Currarino syndrome is characterized by anorectal malformation, a presacral tumor and sacralmalformation. A funnel-shaped anal stenosis causes chronic constipation resulting in the development of megarectum and requires surgical intervention. We present a three-year-old girl with Currarino syndrome consisting of a presacral tumor, anal stenosis andmegarectum associatedwith the thickening of the ...

Introduction. Despite initial enthusiasm, the use of transanal endoscopic microsurgery (TEM) is still quite limited at present because of the expense of highly specialized equipment and the complexity of the learning curve. Furthermore, some authors report a relevant, although temporary, effect on anorectal function because of the considerable anal dilatation which can even produce a rupture of...

INTRODUCTION The main aim of the study was to apply a severity classification of sphincter lesions detected by endoanal ultrasound using Starck score in patients who suffered faecal incontinence. MATERIAL AND METHOD Data were analysed on 133 patients with faecal incontinence. Those in whom anal sphincter lesions were detected by endoanal ultrasound are described and their corresponding scores...

Renal or ureteral diseases are often associated with gastrointestinal symptoms. In this communication, we studied the effect of renal pelvic or ureteric distension on the anorectal function in 12 healthy volunteers. A 3F balloon-tipped catheter was introduced into the renal pelvis. The balloon was filled with saline in increments of 2 ml up to 12 ml and the pressure response of the rectum and a...

The innervation of the puborectalis and external anal sphincter muscles was studied in 32 patients with idiopathic (neurogenic) faecal incontinence, 12 of whom also had complete rectal prolapse, using transcutaneous spinal stimulation, transrectal pudendal nerve stimulation, single fibre EMG, anorectal manometry, and measurement of perineal descent. Fourteen normal subjects served as controls. ...

The association of faecal incontinence with constipation and confusion in the elderly is well recognised but the anal function of faecally incontinent geriatric patients is poorly understood. Anal studies were therefore performed on 99 geriatric patients (49 with faecal incontinence, 19 continent patients with faecal impaction and 31 geriatric control patients with normal bowel habit) and 57 yo...

This study reports on the surgical anatomy and technique of perineal repair in a selected group of parous women with faecal incontinence and/or difficulty in evacuation. Anal sphincter muscle damage is usually attributed to childbirth, although most of these women present for the first time years later. Consecutive patients with the above symptoms were examined clinically and then investigat...

BACKGROUND Long-term results after obstetric anal sphincter injury (OASI) are poor. We aimed to improve the long-term outcome after OASI by lessening symptoms of anal incontinence. METHODS In a prospective study at Malmö University Hospital, twenty-six women with at least grade 3B OASI were classified and sutured in a systematic way, including separate suturing of the internal and external sp...

The primary clinical symptom of Paralytic Shellfish Poisoning is acute paralytic illness produced by paralyzing toxins. Paralytic shellfish poison is formed by a mixture of phycotoxins and their toxicity is due to its reversible binding to a receptor site on the voltage-gated sodium channel on excitable cells, thus blocking neuronal transmission. We studied the effect of the gonyautoxin 2/3 epi...
