Complete rectal prolapse or procidentia is an uncommon condition long recognized but of uncertain pathogenesis. We report two patients, seen a decade apart, both of whom developed complete rectal prolapse after ingestion of oral cathartics in preparation for diagnostic studies. To our knowledge, cathartic-induced complete rectal prolapse has not been reported previously in the current medical literature, despite the thousands of bowel preparations performed annually. These two cases address the implications of such an occurrence, and we discuss the pertinent management issues.

Complete rectal prolapse is uncommon in adults. Out of 129,525 patients treated at our teaching hospital over a five-year period, only 29 patients were managed with complete rectal prolapse. The total mean-age was 52 years with an approximate 1:2 male-female ratio. Two of the patients had their prolapse for 16 years before presentation. Major clinical features included constipation, diarrhoea, soiling and rectal bleeding. 51.72% of the cases had partial to complete incontinence of faeces. 22 patients were treated with the simple technique posterior fixation of both rectum and sigmoid colon. Follow-up was from 6 months to 4 years, mortality was 3.44%. There had been no recurrences of the complete rectal prolapse to date.

Rectal prolapse and solitary rectal ulcer syndrome are both benign conditions affecting the rectum, mainly in women; prolapse tends to occur late in life, while solitary rectal ulcer syndrome has a predilection for the younger adult. Complete rectal prolapse probably starts as a mid-rectal intussusception, although a combination of this theory and the 'sliding hernia' theory has been proposed by Altemeier et al (1971). The pelvic floor weakness associated with prolapse, which gives rise to incontinence, is most likely due to a traction injury to the pudendal nerve. Anorectal manometry will indicate those incontinent patients likely to benefit from rectopexy. Abnormal descent of the perineum may be found in rectal prolapse and solitary rectal ulcer syndrome as well as descending perineum syndrome per se. The clinical features of these three conditions can overlap. Solitary rectal ulcer syndrome is essentially due to prolapse and traumatization of the rectal mucosa. Inappropriate puborectalis contraction, abnormal perineal descent, and overt rectal prolapse have all been cited as possible mechanisms of development of the condition. Defecography is the radiologic investigation of choice. Electromyography, as in rectal prolapse, may show evidence of pudendal nerve damage although incontinence is rare.

Case notes of 250 patients (M:F, 1:2.7; age 48.7 +/- 16.5 years) in whom anterior mucosal prolapse had been diagnosed, at one hospital between 1974 and 1976, were reviewed. The commonest symptoms were bleeding (56 per cent), pain (32 per cent) and a sense of prolapse (32 per cent). The prevalence of constipation was significantly higher among women (47 per cent) than men (29 per cent). Perineal descent was present in 20 per cent of cases and was significantly more frequently associated with excessive straining at defaecation (28 per cent) compared with patients in whom there was no history of excessive straining (12 per cent). Sixty-six patients (26 per cent) experienced recurring symptoms over the 10 year period following presentation but did not deteriorate, while 28 patients (11 per cent) deteriorated. Deterioration was associated with a history of symptoms for longer than 1 year at the time of presentation, female sex, and the presence of perineal descent on clinical examination. The risk of developing perineal descent was less than 10 per cent over the 5 years after presentation while that of developing sphincter laxity among patients who had already developed perineal descent was 30 per cent over this period. Complete rectal prolapse occurred in 20 per cent (3/15) of patients with clinical perineal descent and sphincter laxity but was not seen in the absence of these signs. The results of treatment by submucosal phenol injection, mucosal rubber banding, or glycerine suppositories were the same.
