the purpose of this study is to investigate the age -related improvement of defecation function in high type anorectal malformation in relation to the assessment of the internal anal sphincter. the function of defecation was studied every 5 years up to 15 years postoperatively according to the japanese scoring system in our hospital in 50 patients operated for high type (recto-urethral fistula)...

BACKGROUND Despite the surge of new medical and surgical approaches to treat fecal incontinence, the types of sphincter abnormalities in patients with incontinence have not been well characterized. We aimed to categorize anal sphincter dysfunction using anorectal manometry in patients with fecal incontinence as a potential guide for improved treatment. METHODS A retrospective review of 162 co...

incontinence (gas and liquid stools) shortly after proctologic surgery (fistulectomy). She did not report any obstetric trauma. We performed an anal inspection and a digital rectal examination. There were no anatomical defects, but a severe hypotonic anal sphincter was encountered. Since there is a radial-scanning ultrasound endoscope with frontal vision (Pentax EG3630UR) available in our Unit,...

The effects of serotonin (5-hydroxytryptamine, 5-HT) on the internal anal sphincter were studied in anaesthesized rats. Serotonin induced a dose dependent relaxation of the internal anal sphincter. Methysergide blocked this relaxation, but did not affect the rectoanal reflex. Methysergide did not antagonise the actions of cholinergic and adrenergic agonists on the internal anal sphincter. Other...

PURPOSE Transanal stapled anastomosis has been associated with continence disturbances and reduced postoperative anal sphincter function. The aim of the present work was to study the effect of transanal stapling on anal sphincter morphology by endoanal ultrasound. METHODS Thirty-nine consecutive patients undergoing stapled low anterior resection for rectal carcinoma were assessed. Each patien...

the term ultra short is not clearly defined in ultrashort-segment hirschsprung’s disease. the limited extent of the ultrashort-segment hirschsprung’s disease allows for treatment with extended sphincteromyectomy. in anal sphincter achalasia, anal sphincter dilatation under general anesthesia may be sufficient to treat the condition; in cases with persistent constipation, sphincteromyectomy is i...

Lateral sphincterotomy diminishes internal anal sphincter hypertonia and thereby reduces anal canal pressure. This improves anal mucosal blood flow and promotes the healing of anal fissures. However, sphincterotomy can be associated with long term disturbances of sphincter function. The optimal treatment for an anal fissure is to induce a temporary reduction of anal canal resting pressure to al...

The relation between sensory perception of rapid balloon distension of the rectum and the motor responses of the rectum and external and internal anal sphincters in 27 normal subjects and 16 patients with faecal incontinence who had impaired rectal sensation but normal sphincter pressures was studied. In both patients and normal subjects, the onset and duration of rectal sensation correlated cl...

Injury to the perineum, whether from episiotomy or spontaneous laceration, may result in loss of vaginal or rectal tone and/or anal incontinence. External anal sphincter defects can be identifi ed by endoanal ultrasound in 20% to 53% of women after normal vaginal delivery, a possible risk factor for anal incontinence that will be subsequently reported in 4% to 50% of cases. Flatal incontinence ...
