A prospective study was undertaken to assess the correlation between electromyography (EMG) and cinedefecography (CD) for the diagnosis of nonrelaxing puborectalis syndrome (NRPR). Clinical criteria for NRPR included straining, incomplete evacuation, tenesmus, and the need for enemas, suppositories, or digitation. EMG criteria included failure to achieve a significant decrease in electrical activity of the puborectalis (PR) during attempted evacuation. CD criteria included either paradoxical contraction or failure of relaxation of the PR along with incomplete evacuation. In addition, other etiologies for incomplete evacuation, such as rectoanal intussusception or nonemptying rectocele, were excluded by proctoscopy and defecography in all cases. One hundred twelve patients with constipation, 81 females and 31 males, with a mean age of 59 (range, 12-83) years were studied by routine office evaluation, CD, and EMG. Forty-two patients (37 percent) had evidence of NRPR on CD (rectal emptying: none, 24; incomplete, 18). Twenty-eight of these patients (67 percent) also had evidence of NRPR on EMG. EMG findings of NRPR were present in 12 of 70 patients (17 percent) with normal rectal emptying. Conversely, 14 of 72 patients (19 percent) with normal PR relaxation on EMG had an NRPR pattern on CD. The sensitivity and specificity for the EMG diagnosis of NRPR were 67 percent and 83 percent, and the positive and negative predictive values were 70 percent and 80 percent, respectively. Conversely, if EMG is considered as the ideal test for the diagnosis of NRPR, CD had a sensitivity of 70 percent, a specificity of 80 percent, and positive and negative predictive values of 66 percent and 82 percent, respectively. In summary, sensitivity, specificity, and predictive values of EMG and CD are suboptimal. Therefore, a combination of these two tests is suggested for the diagnosis of NRPR.

Internal procidentia or internal rectal prolapse (intussusception) still represents a therapeutic problem: it may be a secondary phenomenon in a primary functional disorder, or it may itself represent the cause of outlet obstruction amenable to cure by prolapse operation. Over a 10-year period 49 patients underwent surgery due to severe symptoms and resistance to conservative treatment. Symptoms and findings were obstructive constipation (65%), tenesmus and pain (55%), mucus discharge and bleeding (26%), and incontinence (24%). 12 (24%) of the patients had a solitary rectal ulcer syndrome. The operative procedure consisted in rectal mobilization, elevation, rectopexy, with rectosigmoid resection in 45 patients. 1-9 (mean 3) years after the operation 10 patients (21%) had a poor functional outcome, though the intussusception was cured in 48 patients. A favorable result was most frequently noticed in patients with incontinence, incipient external prolapse, and also in those with a solitary rectal ulcer syndrome. 35% of the patients with obstruction, severe pain and normal continence did not benefit from the operative procedure.

A study of one hundred and forty-two patients with acute intestinal obstruction over a period of ten years (January 1985-December 1994) at Wesley Guild Hospital was undertaken to determine the pattern and outcome of this problem in a tropical African population. There was a preponderance of males over females; ratio 1.7:1. Mean age was 33 years and over half of the patients were aged between two and 30 years. There was a second peak age incidence among elderly patients between 50-80 years. Abdominal pain, vomiting and constipation were common symptoms, while abdominal distension and tenderness were common clinical findings. Intraperitoneal adhesions were responsible in 41.5%; there was associated intestinal volvulus in 25.4% of the cases of intraperitoneal adhesions. In 16.9%, strangulated external hernia was responsible for acute intestinal obstruction. Small intestinal volvulus was encountered in 20 cases (14.1%) and associated with adhesion in 75% of the cases. Intussusception occurred in 14.1% of cases of which 70% of the patients were below the age of 15 years. In 15 (10.6%) patients, there were volvulus of the sigmoid colon, with 80% (12 patients) having gangrenous bowel segments. Ascaris were responsible in 3.5% of the patients and large bowel tumour in 2.8%. Other rare causes were internal hernia and ileal pseudo obstruction. Adhesiolysis and intestinal resection were the commonest operative procedures. Common complications were wound infection in 16.2%, postoperative fever in 10.6% and chest infection in 9.1%. A mortality rate of 8.4% was recorded.

Colonic lipomas are often asymptomatic, but large lipomas may produce abdominal pain, diarrhea, constipation, hemorrhage, and intussusception. We report a young woman with a colonic lipoma who presented as an acute abdominal emergency with total colonic obstruction and severe pain associated with intussusception and extrusion of the tumor through the anus. The case was interesting because of its presentation after a double-contrast barium enema and because of the patient's young age and the tumor's location on the left side of the colon.

Constipation and defecation may be considered as the last taboo. The inability to defecate or to achieve this only by digital evacuation has never been a popular topic among patients and doctors. Application of tests from the colorectal laboratory has made it possible to study the function of the different parts of the colon and the mechanism of continence. We consider transit studies, defecography, EMG, and anal manometry, all useful as diagnostic procedures for functional constipation. Several causes of functional constipation can be distinguished in slow transit and difficult evacuation or colonic inertia, spastic pelvic floor syndrome, rectocele and intussusception. This article presents our view of the assessment and management of functional constipation.

Defaecation disorders may be subsumed in three categories: Inability to control motions = incontinence. Difficulty of evacuation = constipation [inertia coli, outlet obstruction]. Impeded defaecation: Rectocele, enterocele, intussusception. Etiology, examination and therapy are described in detail. Characteristic complaints of patients are listed and matched with probable diagnoses. Beside routine proctologic examination endosonography, estimation of transit time, endoscopy and defecography are discussed. The role of nutrition is stressed and emphasis layed on fibre and fluid intake. The advice, "take more fluid and fibres" does not help a lot, because no individual help is given. A time consuming nutrition and defaecation history has to be taken to establish nutritional support. This attention gives confidence to the patient and helps a great deal in the treatment. A checklist of the therapy of constipation and summarizing tables on different types of fibres are included. Additional conservative treatments are pelvic exercises and biofeedback training. Operative therapy is directed towards etiology of the disorder. Therefore many different methods exist and their diagnose related indication are discussed.

Rectal prolapse is the transposition of the entire rectal wall into the rectal lumen, the anal canal or through the anal canal out side. It differs from anal prolapse in thickness, circular plication of the mucosa and, if large, its extent. The cause is not clearly established, but disorders in bowel movement seem to be of importance. Symptoms reach from the feeling of incomplete evacuation to defecation block and irreducible prolapse. The diagnosis of outer prolapse is easy. The inner prolapse [intussusception] can be suspected by anamnesis and in the presence of solitary rectal ulcer. Defecography gives the conclusive examination. Conservative therapy is analogous to hemorrhoids: Fibres and sufficient liquid intake. Operative procedures can be divided in transabdominal and perineal procedures. From the latter Delorme's procedure gives good results with low stress for the patient. Of the transabdominal procedures we favor rectopexy with Ivalon-sponge, preservation of the lateral bands and sigmoid resection. This procedure can easily be done by laparoscopy. Postoperative constipation is observed above all if the lateral bands are dissected and no sigmoid resection is done. Preexistent constipation Improves in about 50% of the cases. Same does incontinence.

Acute and chronic constipation are common conditions. In most instances, a thorough history and digital rectal examination provide sufficient information to begin treatment. Occasionally, imaging studies can be useful to confirm the presence of a suspected abnormality. The acute onset of constipation suggests colonic obstruction. Plain abdominal radiographs may be sufficient to determine the level and cause of the obstruction, such as sigmoid or cecal volvulus. Barium enema radiographic examination or colonoscopy may also be useful to detect the cause of obstruction. In patients with chronic constipation, plain abdominal radiographs can be used to show the extent of fecal impaction. Colonic transit time can be assessed on serial abdominal radiographs after the patient has ingested radiopaque markers. Evacuation proctography can be used to diagnose a variety of functional disorders of the rectum and anus, such as rectocele, intussusception and abnormal perineum floor descent.

Solitary rectal ulcer, internal rectal intussusception, and complete rectal prolapse are a range of defaecatory disorders that may have a common aetiology, namely chronic straining. If the pelvic floor is weak, external prolapse is often complicated by faecal incontinence. Few patients, a lack of randomised trials, and difficulties in the interpretation of studies of anorectal physiology (the results of which often seem conflicting) have made the understanding of these disorders difficult. The basis for treatment is clear, however--patients who have symptomatic defaecatory disorders associated with an internal intussusception, or solitary rectal ulcer, or both should have a course of training of pelvic floor muscles, dietary advice, and should use fibre supplements as primary treatment. Operation should be reserved for those patients in whom medical treatment has failed, and it may be expected to relieve symptoms in above two thirds of patients. Defaecating proctography may be useful in assessing which patients may not benefit from operation. Operation is the primary treatment for external prolapse. The choice of surgical approach should be tailored according to the expertise available, the medical condition of the patient, and the presence or absence of pre-existing constipation or incontinence.

Rectal and colonic X-ray findings of 100 patients with constipation are presented. The study was performed by the authors' modified irrigoscopic procedure using barium enema. This made it possible not only to determine the shape, dimensions, and position of the rectum and colon, but to reveal a number of anatomic and functional changes in the rectum and pelvic floor (rectocele, rectal intussusception and prolapse, perineal descent, sigmoidocele), which was helpful in choosing a treatment policy for patients with colonic evacuatory dysfunction.
