Internal rectal intussusception--fact or fancy?

PURPOSE: There is still considerable debate whether internal intussusception represents a functional disorder. We have reviewed our results in an effort to define its symptomatology and to assess defecography. METHODS: Rectopexy has been performed for internal intussusception in 37 patients. Eighteen had solitary rectal ulcer syndrome (SRUS), and 31 had anterior rectal wall prolapse. Defecography demonstrated anterior wall prolapse in 13, circular prolapse in 21, and no disorders in 3 patients. Pelvic floor function was normal. Follow-up varied from one to nine years. RESULTS: Twenty-six patients became asymptomatic. Anterior wall prolapses could not be palpated anymore. All SRUS lesions healed. Patients with SRUS (P < 0.001) or circular prolapse (P < 0.001) became significantly more asymptomatic. Results in patients with anterior rectal wall prolapse were significantly worse (P < 0.001). CONCLUSIONS: Internal intussusception is a distinct functional rectal disorder. Its symptomatology and findings during physical examination are aspecific. Characteristic defecographic features and presence of SRUS are indications for surgery, provided pelvic floor function during straining is normal.

[Obstructive defecation. Diagnostic methods and treatment].

Obstructive defecation is observed in approximately half of all patients with functional constipation. Functional constipation has been related to alterations in intestinal motility (slow transit constipation) and to pelvic floor disorders leading to obstructive defecation associated with anatomical alterations of the pelvic floor (rectocele, posterior perineal hernia, enterocele and sigmoidocele, internal rectal intussusception, occult mucosal prolapse, solitary rectal ulcer and descending perineum syndrome), or obstructive defecation without anatomical alterations (pelvic floor dyssynergy or anismus). The diagnostic methods used (history and physical examination, colonic transit time, balloon expulsion test, proctography, anorectal manometry and electromyography) are reviewed. Conservative medical treatment and the indications for surgical treatment and its results are also discussed.

Squamous cell carcinoma in situ arising in inflammatory cloacogenic polyps: report of two cases with PCR analysis for HPV DNA.

Inflammatory cloacogenic polyp (ICP) is regarded as part of the spectrum of pathological changes encountered in mucosal prolapse syndrome (MPS)/solitary rectal ulcer. We present the clinicopathological features of two females with squamous cell carcinoma in situ arising in their ICPs. Human papillomavirus (HPV) type 16 was demonstrated in the areas of squamous carcinoma in situ in both polyps by polymerase chain reaction. These cases highlight the need for close scrutiny of the squamous components of these lesions.
