Anorectal disorders that disturb normal defecation are described, especially intussusception of the rectum (internal procidentia). A review of 190 patients, half of whom were treated operatively and the other half conservatively, is presented. Diagnostic procedures, symptoms, and indications for operations are evaluated. We believe that intussusception of the rectum is a relatively common cause of difficult emptying of the rectum and, when the correct diagnosis is established, operation presents a fair chance for improvement.

We present three cases of prolapse of ureteral tumor. Prolapse of a ureteral tumor is usually associated with antegrade intussusception of the ureter, and is thought to be a sign of noninvasiveness. In such a case segmental ureterectomy may be justified.

Among the 80 different techniques that have been devised to repair rectal prolapse, abdominal rectopexies are the most suitable. The majority of these operations secure the rectum to the sacrum by means of a prosthetic material. Ripstein's technique, in USA, and Wells procedure, in Great Britain, have gained wide acceptance, despite a rather high rate of complications. A modified technique has been recently proposed by Keighley et al., with excellent results. From 1979 to 1982, 20 patients were operated upon in our department for rectal prolapse. The mean age of the patients was 43 years, and there was a rather high percentage of male patients (30%). Eleven exhibited an obvious external prolapse patients (30%). Eleven exhibited an obvious external prolapse but the others complained of the "occult rectal prolapse syndrome". The Orr-Loygue procedure, that secures the rectum to the sacral promontory by means of two strips of nylon mesh, was performed in all these cases. No mortality was observed and the morbidity was minimal. No infectious complications occurred. The procedure was performed without sexual consequences in the young patients. Clinical, endoscopic and cineradiographic checks illustrate that the Orr-Loygue rectopexy is an efficient treatment of both incipient intussusception and external prolapse, and offers good control of most associated troubles. But a longer survey is necessary before definitive conclusions may be drawn.

The classical abnormalities found in patients with complete rectal prolapse--wide deep pelvic peritoneal pouch, unsupported redundant rectum with long mesorectum, weak pelvic floor and anal sphincters--are probably effects rather than causes. "Pelvic floor weakness" must explain few cases, since old age, multiparity, uterine prolapse, are found in a minority. The fact that operations which do no more than fix the rectum in the sacral hollow are most successful and often cure incontinence if present is the best evidence that lack of support of the rectum is a prime cause of prolapse--but it is equally likely that such operations work by preventing intussusception, now regarded as the likely mechanism (rather than sliding herniation) of complete rectal prolapse. It is suggested that rectal prolapse is usually due to straining at defaecation against a closed levator-ani--anal-sphincter mechanism, producing prolapse of the rectum rather than incontinence of faeces. Such straining may be obsessive on the part of patients with psychosocial problems and reduced awareness that the rectum is empty; or it may be due to attempted defaecation with a full rectum in patients with reduced rectal sensation, failure of the afferent arc of the ano-rectal reflex and consequent absence of levator-ani--anal-sphincter relaxation.

The various modified fixation procedures used for rectal prolapse take into account the pathophysiologic concept of complete prolapse of the rectum as a sliding hernia of the pouch of Douglas. The possibility of intussusception by reinforcement of the wall of the extensively mobilized rectum was successfully prevented by a new technique. The use of this simple technique in another form of prolapse, namely, prolapse of the terminal colostomy, convinced us to its usefulness.

Inflammatory cloacogenic polyp (ICP) is a rare lesion arising in the region of the anorectal transitional zone. It is likely caused by occult internal prolapse. Most cases reported in the literature are in the adult population. This is a report of ICP in four children. Awareness of this entity in children is important because of both the propensity for recurrence or persistence of the polyps if the underlying etiology is not corrected, as well as the long-term implications of internal intussusception: procidentia, descending perineum syndrome, and ultimately, incontinence.

Ectopic pancreas is the most common congenital anomaly in the gastric antrum. In some patients, there is a distinct tendency for this lesion to produce intermittent crampy abdominal pain by provoking gastroduodenal prolapse. This condition should be considered after a more distal prolapse from intussusception is excluded. An upper gastrointestinal series performed during an episode of symptoms may be diagnostic of this entity.

Gastroduodenal intussusception is a rarely documented condition. A distinction has to be made between complete gastroduodenal intussusception (CGDI) and either prolapse of a pedunculated tumor through the pylorus or mucosal prolapse through the pylorus. CGDI usually occurs secondary to a pedunculated benign gastric tumor. More rarely the tumor is malignant. We report a case of CGDI associated with gastric adenocarcinoma. We emphasize diagnostic difficulties that can be generated by CGDI.

In the present work the Authors have studied 19 patients with occult rectal prolapse evaluating symptoms and functional results after posterior abdominal rectopexy. Symptoms of internal rectal procidentia appear as a definite syndrome. In our patients pain upon defecation, this being often localized to the perineal and sacral region, was observed in 14 on 19 cases, while fecal incontinence was present in 5 cases (29%) and rectal bleeding in 8 (44%). These compliances are relieved by the anatomical correction of the rectal intussusception, but the preexisting functional disorders in the mechanism of defecation appear to be unaffected by rectopexy. (Sensation of obstruction 11 cases (58%) preop. e 9 cases (53%) postop.).

Videoproctography has proved to be a useful diagnostic technique to investigate anorectal disorders; it can provide morphological and functional information which no other diagnostic method yields. From a series of 898 videoproctographs, the findings of 117 patients with rectal intussusception were retrospectively reviewed. The most common symptoms were an incomplete emptying feeling (93% of cases), obstructed defecation (78%), and a feeling of upright rectal weighting (71%). Of the three known types of rectal intussusception, the most common type was distal intussusception (44%), followed by the rectoanal type (38%) and finally by the proximal type (19%). The three types of intussusception were frequently (42%) associated with other disorders of rectal ampulla and especially with rectocele (15%), mucosal prolapse (8%), and descending perineum syndrome (12%); they had different clinical correlations and proctographic patterns and could be recognized in different defecation phases. In our personal experience, proctography with videorecording was a useful diagnostic tool in the dynamic assessment of this morphofunctional disorder which represents one of its major indications.
