Transrectal ultrasonography is of clinical value in anorectal carcinoma and in inflammatory diseases of the anorectum. In this study a rigid linear endorectal probe was used to examine 15 patients with endoscopically and biopsy proved diagnosis of solitary rectal ulcer syndrome. In 13 of the 15 patients the rectal wall was thicker (mean (SEM) 5.7 (0.4) mm; normal values: 2.8 (0.1) mm) near the rectal ulcer. In all these cases the muscularis propria layer exceeded the maximum normal diameter of 2 mm. In nine of the 15 patients the normal rectal wall echo-structure, with five distinct layers, was disturbed and there was fading of the borders between the mucosa and the muscularis propria. Poor relaxation of the puborectalis muscle during straining was seen on ultrasound in 11 patients, as was intussusception of the rectal wall. The obvious enlargement of the muscularis propria points to a chronic mechanical load on the rectal wall. The ulcerative lesions are formed in this area of overloaded rectal wall. The direct visualisation of the puborectalis muscle during dynamic transrectal ultrasonography indicates that the fact that it does not relax is an important element in the pathogenesis of solitary rectal ulcer syndrome.

A criterion for successful hydrostatic reduction of intussusception is reflux into the terminal ileum. In our practice, absence of reflux into the terminal ileum is not an indication for laparotomy if the radiographic appearances suggest edema of the ileocecal valve. The aim of this study was to validate our approach. We reviewed the case notes of patients with a diagnosis of intussusception (n = 107; age 11.74 +/- 1.48 months; mean +/- SEM) treated from 1987 to 1991. Eleven required primary laparotomy for peritonitis. Ninety-six patients who had a contrast enema were studied. Edema of the ileocecal valve was defined as a persistent filling defect in the cecum after apparently complete hydrostatic reduction, without reflux of contrast into the distal small bowel. In 59 patients hydrostatic reduction was successful: 11 (18.6%) had edema of the ileocecal valve and no reflux contrast into the terminal ileum (group B). All improved clinically after the enema and needed no further treatment. In 37 patients hydrostatic reduction of the intussusception was unsuccessful and an operation was performed: 26 (70.3%) required manual reduction of the intussusception (group C) and 11 (29.7%) underwent bowel resection (group D). None of the patients with edema of ileocecal valve required further treatment or developed recurrent intussusception. In none of the patients who had an operation was the intussusception found to have been reduced by the contrast enema. There were no deaths.(ABSTRACT TRUNCATED AT 250 WORDS)

The management of rectal internal mucosal prolapse (RIMP) is not based on an accepted classification of the lesion which helps to choose the appropriate treatment. The aim of this prospective study was to report a new endoscopic grading of RIMP and to evaluate its clinical value. Thirty-two patients (7 men, 25 women; mean age 56 years, range 28-72) affected by symptomatic RIMP were prospectively classified as follows: RIMP was defined as first degree when detectable below the anorectal ring on straining, as second degree when it reached the dentate line, and as third degree when it reached the anal verge. Anal manometry was carried out in 26 patients, and anal ultrasound and defecography in 6 prior to surgery. A correlation was found between the occurrence and severity of symptoms and the degree of the prolapse as obstructed defecation, bleeding and fecal soiling affected mainly patients with third-degree RIMP. At manometry the maximal resting tone was 60+/-23 mm Hg and voluntary contraction 96+/-41 mm Hg (mean+/-SEM). At anal ultrasound the mean internal sphincter thickness was 2.1+/-0.2 mm, and external sphincter thickness was 7.0+/-0.8 mm. A significant rectocele and rectal intussusception (n = 2) and a nonrelaxing puborectalis muscle on straining (n = 2) were observed at defecography in cases with third-degree RIMP. The anorectal angle was 100+/-75 degrees at rest, 63+/-20 degrees on squeezing, and 115+/-9 degrees on straining. A conservative treatment with high-fiber diet and/or rubber band ligation was carried out in all cases of first and in most patients with second-degree RIMP (n = 26). Those who required surgery, i.e., stapled transanal excision of the prolapse (n = 6), had either severely symptomatic third-degree RIMP with solitary ulcer syndrome (n = 4) or second-degree RIMP (n = 2). A positive outcome was achieved in 71% of cases. The proposed classification evaluated by the present study may be of clinical value in managing rectal internal mucosal prolapse.
