Methods used to improve the accuracy of diagnosis of acute appendicitis are reviewed. Laparoscopy, barium enema, ultrasonography and computer assistance have all been shown to improve accuracy, but no one method is of proven superiority. Such diagnostic aids or intensive in-hospital observation must be used to reduce the 15-30 per cent negative laparotomy(More)
INTRODUCTION Rectal function following rectal resection for carcinoma was studied in 43 patients. METHODS Sixteen women and 27 men with a median age of 66 years (range 41-79 years) were included. Twenty-three patients had a diverting ileostomy at the time of resection. Eight patients had a 6-cm colonic J-pouch. Ten patients had anastomotic leakage(More)
Knowledge of the normal sonographic features of the anal canal is essential for the detection of anal carcinomas, anal sphincteric defects, or other anal abnormalities with endosonography. The anal sphincters consist of the circular smooth muscle fibers of the internal sphincter and the circular striated muscle fibers of the external sphincter together with(More)
The anal sphincter muscles consist of the circular internal and external sphincters together with the sling-shaped associated puborectalis muscle. Ten men, 10 women with no vaginal deliveries, and 10 women with one or more vaginal deliveries were studied with anal endosonography using a 7 MHz multiplanar endoprobe. The thickness of the internal sphincter(More)
Anal endosonography, including measurements of anal sphincter size, was performed in 16 patients with obstructed defecation. The findings were compared with those at defecography and anal manometry. Patients with rectocele and intussusception had a normal endosonographic appearance. One patient with puborectalic spasm had normal sonography. There was no(More)
BACKGROUND The surgical options for the treatment of anal incontinence where standard procedures have failed include transposition of striated muscles, primarily gracilis and gluteus maximus, and implantation of artificial sphincters. Due to a high proportion of fatigue-prone fibres in striated muscles, the results of transposition without stimulation have(More)
Follow-up was performed two to six years after anal dilatation for fissure-in-ano in 32 consecutive patients who had not undergone additional anal surgery. All patients were interviewed and asked specifically about impairment of flatus or fecal control and its possible relation to the anal dilatation. Anal dilatation was followed by minor anal incontinence(More)
Transposition of the gracilis muscle for faecal incontinence was performed in 13 patients. Six gained satisfactory continence, four were improved, two did not benefit from the operation and one patient died from intercurrent disease before closure of a pre-existing colostomy. Anal manometry compared with a control group showed no alteration in resting and(More)
Thirty-eight women with rupture of the anal sphincter occurring during childbirth were followed for 3-12 months. Nineteen had complete rupture of the external anal sphincter, 14 had a lesion involving more than half of the sphincter muscle and five had a superficial rupture. Fourteen patients presented with continence disturbances: nine to solid or liquid(More)
BACKGROUND Patients suspected of having perianal suppurative disease often undergo a combination of several potentially painful, invasive procedures to establish or rule out the diagnosis. To evaluate the accuracy of low-field magnetic resonance imaging (MRI) in distinguishing patients with active anal fistulae and patients with no active fistulation we(More)
