A consecutive series of 58 patients with idiopathic constipation and 20 control subjects were studied by evacuation proctography and measurements were made of changes during rectal expulsion. A wide range was found in the control group. The anorectal angle, pelvic floor descent, and the presence or size of an anterior rectocele did not discriminate between the control and patient groups. Internal intussusception was rare. Among constipated patients, the only significant differences from normal were in the time taken to expel barium and the amount of barium remaining in the distal rectum. The majority of control subjects (15 of 20) evacuated most of the barium within 20 seconds whereas 45 of 58 constipated patients took a longer time. Using the area of barium on a lateral view of the rectum as a measure, 19 of 20 control subjects evacuated at least 60 percent of the barium from the distal 4 cm of the rectum compared with only 25 of 58 patients. A varying degree of defecatory impairment was thus established among many patients with constipation. The patients were subdivided into those with a normal or abnormal whole gut transit rate as an indication of colonic function, and those who did or did not need to digitally evacuate the rectum as a clinical manifestation of an anorectal disorder. No obvious differences were found between these subgroups using the parameters measured.

Defecographic evaluation was performed in 30 patients with rectal prolapse to assess the effect of posterior rectopexy on rectal function and to arrive at a selection of the best procedure. Preoperative defecography revealed rectal intussusception in all patients. Postoperative control studies showed adequate rectal fixation to the anterior sacral surface. Intussusception no longer occurred. Rectal stenosis due to the surgical procedure was absent. The described technique of posterior rectopexy eliminates the prolapse mechanism without creating new disorders and is therefore a rational procedure. Advocation of new procedures should also be based on results of colorectal tests that assess the effect of the procedures on rectal function.

A four-year-old boy had a cecoanal intussusception prolapsing through the anus. A 4 x 4 cm cecal tumor served as the leading point of the intussusception. Laparotomy and histology revealed that the tumor was a solitary Burkitt's lymphoma of the cecum. Isolated Burkitt's lymphoma, as presented here, is rare, and such a combination has never been reported. Intussusception prolapsing through the anus and Burkitt's lymphoma are discussed, as well as a possible reason for the rarity of the condition.

Forty-four patients presenting with painful outlet constipation had internal rectal intussusception documented by cinedefecography. Rectal reservoir reduction by multiple elastic ligation or staple excision of redundant mucosa effectively improved bowel function and outlet symptoms in the majority of patients. Rectal reduction procedures were performed under intravenous sedation with antibiotic coverage, no postoperative sepsis, and a single case of significant postoperative bleeding. Associated abnormalities on defecography were unaffected.

Two cases of symptomatic submucosal lipomas of the large intestine are described. One occurred in a patient with familial multiple lipomatosis causing an intussusception and intermittent obstruction. The other caused subacute obstruction and rectal bleeding and was thought to represent a carcinoma. These two cases closely resemble those few patients with symptomatic lipomas of the colon that make up a small subgroup (6 percent) of a series of 91 patients with this diagnosis managed surgically at the Mayo Clinic between the years 1976 to 1985. The majority of patients in this series had lipomas that were entirely incidental findings usually associated with more significant pathology that dictated the operative procedures undertaken. Lipomas themselves may be managed by local excision only although segmental resection may be necessary in isolated cases.

Experimental data have led to the conclusion that a transanal partial or subtotal colonic resection can safely be performed in the dog without entering the peritoneal cavity. The techniques of intussusception of the colon at the anus and resection of the colon at the perineum with modified use of the EEATM stapler are presented.

The solitary rectal ulcer and colitis cystica profunda are different manifestations of the solitary rectal ulcer syndrome. The cause of solitary rectal ulcer syndrome remains unknown. Since defecation disorders are common among patients with solitary rectal ulcer syndrome, defecography is indicated. Defecography was performed on 19 patients with solitary rectal ulcer syndrome. In five patients, the spastic pelvic floor syndrome had occurred. Twelve patients had internal intussusception of the rectum, and one patient had an anterior rectal wall prolapse. In one patient, no abnormalities could be detected. These abnormalities led to severe straining, which can damage the anterior rectal wall. Findings strongly support the hypothesis that solitary rectal ulcers are traumatic lesions caused by straining. Defecography is a suitable procedure for detecting the causative disorder of defecation and for selecting patients for treatment.

Two children were admitted for clinical and radiologic signs of small-bowel obstruction. Examination revealed an abdominal mass that was suspected of being a mass of intussusception. Bowel obstruction caused by Ascaris lumbricoides was found at surgery. The laboratory, radiologic, and surgical findings are presented with a short review of the literature with emphasis on diagnosis, incidence, complications, and treatment.

In this paper, an account is given of our experience with continent colostomy in man. In five patients, the end-sigmoidostomy was provided with an intussusception valve. Evacuation of the bowel by irrigation through a catheter was laborious and time-consuming and this method was abandoned. In another group of 30 patients, the cecum was isolated from the rest of the colon and its distal end was provided with an intussusception valve. Of the 30 patients, eight were later given continent ileostomies, two were converted to conventional sigmoidostomies, and one patient with fecal incontinence preferred to have intestinal continuity reestablished. Thus, 19 patients still have continent cecostomies and are satisfied with their function. When comparing the function of the continent cecostomy with that of the continent ileostomy, however, it is obvious that the ileostomy function is superior. The experience obtained with this group of patients has resulted in a widening of the indications for constructing a continent ileostomy, including selected patients with various anorectal disorders.
