Defecography is a technique of examining the rectum and anal canal in which the patient is studied while sitting down rather than recumbent and recordings are obtained both at rest and during straining. The authors describe their findings in 83 patients with dyschezia. Defecation was normal in 28 patients. Prolapse of the anal mucosa was seen in 13 patients and internal procidentia in 23, 12 of whom also had intussusception manifested as rectal prolapse. A deep rectogenital fossa associated with an enterocele was seen in 16 patients; 13 had a proctocele, while fecal retention was seen in 5. Descent of the pelvic floor and changes in the angle between the rectum and anal canal were assessed. The authors recommend defecography as a more physiological means of assessing rectal dysfunction.

The descending perineum syndrome, described in 1970 by Alan Parks, remains difficult to interpret clinically and pathophysiologically. A general review of descending perineum was conducted, based on review of the literature published between 1966 and 2004, and retrospective analysis of 1,023 colpocystograms. The symptoms observed are usually secondary to associated lesions. Radiological signs of descending perineum are not always associated with clinical symptoms. Colpocystogram shows perineal descent and associated disorders of anterior and middle pelvic tone, while defecography provides a better explanation for dyschezia which is generally due to an associated posterior disorder (rectocele with rectal intussusception). The management of descending perineum is based on medical treatment and retraining. No consensus has been reached concerning surgical management. Surgery is generally used to treat associated lesions. In the case of complete collapse of perineum, an abdominal approach with infravesical, prerectal and retrorectal tension-free tape to the sacrum could be useful, while transanal staple repair of the rectum could be proposed when descending perineum is associated with only rectal intussusception or rectocele.

Dyschesia, also called obstructed defecation syndrome (ODS), is a difficulty to exonerate with straining. A rectocele or an intussusception are the main causes. Defecation is facilitated by digital maneuvers into vagina in case of rectocele or on the perineum in intussusception. Clinical examination is conducted at rest and at strain allowing exposing the rectocele. Vaginal valves may allow differentiating an anterior colpocele to a rectocele. An anterior rectal hernia should be accentuated by digital examination of the rectum. Clinical examination in intussusception is poor. An ODS scoring is useful to determine the severity of the symptoms and to appreciate the therapeutic results comparing pre- and post-treatment scores.

Chronic constipation is caused by disordered colonic motility, impaired rectal evacuation (dyschezia) or a combination of the two. It is important to distinguish the predominant mechanism of constipation in order to choose the optimal therapy (laxatives or prokinetics versus pelvic floor retraining or surgery). The contribution of dyschezia to constipation can usually be identified by a digital rectal examination, but should, in our opinion, be confirmed by anal manometry, transrectal ultrasonography or defecography. These diagnostic methods provide additional information on the severity of the rectal outlet obstruction, the contribution of rectal hyposensitivity and the presence of potentially correctable anomalies such as a rectocele, enterocele or rectoanal intussusception. We conclude that clinical anorectal examination and functional studies are both necessary and complementary to each other in the evaluation and management of patients with chronic constipation who do not respond to standard laxative treatment.

An approximately four-year-old male castrated guinea pig (Cavia porcellus) was presented for painful defecation with a 24-hour history of hyporexia and intermittent episodes of rolling behavior. Upon presentation the patient was quiet, alert, and responsive, and mildly hypothermic. Abdominal palpation revealed an approximately 2-cm long oblong mass within the caudal abdomen. Abdominal radiographs revealed gastric dilation without volvulus and a peritoneal mass effect. The patient was euthanized following gastric reflux of brown malodorous fluid from his nares and oral cavity. A necropsy was performed and revealed a jejuno-jejunal intussusception causing mechanical gastrointestinal ileus, and gastric dilatation without volvulus. While non-obstructive gastrointestinal stasis is common and obstructive ileus is uncommon in guinea pigs, this report shows that intestinal intussusception is a differential in guinea pigs with ileus and gastric dilatation.

Adult intussusception is a rare clinical condition. In majority of adult cases, there is an underlying cause such as polyps or colon cancers. In the present study, a 29-year-old woman with intermittent and colicky abdominal pain, constipation, and painful defecation, accompanied with distention and sense of rectal fullness, was evaluated with computed tomography. Ileo-colo-colic intussusception was determined. Subtotal colectomy with posterior rectopexy was performed. After the surgery, she was doing well at 13-month follow-up.
