  • Pathology of the Rectal wall in solitary Rectal ulcer syndrome and Complete Rectal Prolapse.
    Gut, 1996
    Co-Authors: Y S Kang, A F Engel, Michael A Kamm, Ian C. Talbot
    Abstract:

    BACKGROUND--The aetiology and pathology of Rectal Prolapse and solitary Rectal ulcer are poorly understood. AIMS--To examine the full thickness Rectal wall in these two conditions. METHODS--The pathological abnormalities in the surgically resected Rectal wall were studied from nine patients with solitary Rectal ulcer syndrome, 11 Complete Rectal Prolapse, and nine cancer controls. Routine haematoxylin and eosin and Van Gieson staining for collagen were performed. RESULTS--The Rectal wall from solitary Rectal ulcer syndrome specimens was thickened compared with Complete Rectal Prolapse and controls. The major difference was in the muscularis propria (2.2 v 1.1 v 1.2 mm, medians, p < 0.005) and particularly the inner circular muscular layer, and to a lesser extent the submucosal and outer longitudinal muscular layers. Some solitary Rectal ulcer syndrome specimens showed unique features such as decussation of the two muscular layers (four of nine), nodular induration of inner circular layer (four of nine) and grouping of outer longitudinal layer into bundles (three of nine); these were not seen in Complete Rectal Prolapse or control specimens. CONCLUSIONS--These features, which resemble the features of high pressure sphincter tissue, may be of aetiological importance, and suggest a different pathogenesis for these two disorders. Excess collagen was seen in both disorders, was more severe in solitary Rectal ulcer syndrome specimens, and probably reflects a response to repeated trauma.

  • SOLITARY Rectal ULCER AND Complete Rectal Prolapse: ONE CONDITION OR TWO?
    International Journal of Colorectal Disease, 1995
    Co-Authors: Y S Kang, Michael A Kamm, Ralph. J. Nicholls
    Abstract:

    We studied the physiological features of patients with Complete Rectal Prolapse and different degrees of solitary Rectal ulcer syndrome to determine whether these conditions are likely to form part of the same disorder. 52 solitary Rectal ulcer patients (median age 31, 40 females), and 15 Complete Rectal Prolapse patients (median age 31, 12 females) were studied. Solitary Rectal ulcer patients were divided into 3 groups, based on the extent of accompanying Rectal Prolapse (no Prolapse, internal Prolapse, or external Prolapse). Both solitary Rectal ulcer patients without Prolapse and with internal Prolapse had significantly higher maximum anal resting (p

  • solitary Rectal ulcer and Complete Rectal Prolapse one condition or two

Solitary Rectal ulcer patients were divided into 3 groups, based on the extent of accompanying Rectal Prolapse (no Prolapse, internal Prolapse, or external Prolapse). Both solitary Rectal ulcer patients without Prolapse and with internal Prolapse had significantly higher maximum anal resting (p<0.01 for both groups) and squeeze pressure (p<0.05 for both groups) than Complete Rectal Prolapse patients. In contrast, solitary Rectal ulcer patients having external Prolapse were similar to those with Complete Rectal Prolapse. Solitary Rectal ulcer patients without Rectal Prolapse had significantly decreased anal and Rectal electrosensitivity (p<0.01 for both) when compared to healthy control subjects. Solitary Rectal ulcer patients therefore have a spectrum of clinical and physiological features — this condition may comprise a range of different disease entities. The findings also suggest a different underlying aetiopathophysiology of solitary Rectal ulcer from that of Complete Rectal Prolapse.

  • combined thiersch s procedure and subanodermal coagulation for Complete Rectal Prolapse in the elderly
    Digestive Surgery, 2006
    Co-Authors: Pravin J. Gupta
    Abstract:

    Background: The author describes a modification of Thiersch’s procedure in patients with Complete Rectal Prolapse by inducing fibrosis at the anal verge through circumferential subanodermal coagulation using a radiofrequency device. Materials and Methods: An Ellman radiofrequency generator was used for coagulation. The postoperative events were recorded. The patients were followed over a period of 2 years to assess late outcome. Results: Postoperative complications were observed in 2 patients. One of these developed suppuration in the tract of the encircling wire that needed removal, while the other had a recurrence due to loosening of the wire. At a 2-year follow-up, 3 patients developed recurrence while 1 had a persistent complaint of fecal incontinence. Conclusion: This study shows that a combined procedure of radiofrequency coagulation followed by Thiersch’s circumanal wiring is quick and easy to perform with no formidable morbidity in elderly patients who are otherwise considered at high risk for definitive surgical procedures.

  • experiences of ivalon sponge implant for Complete Rectal Prolapse at st mark s hospital 1960 70
    British Journal of Surgery, 2005
    Co-Authors: J. C. B. Penfold, P. R. Hawley
    Abstract:

    Experience of using Ivalon-sponge implants in 101 patients with Complete Rectal Prolapse at St. Mark's Hospital is reviewed. It is a straightforward operation with minimal complications producing long-term control of the Prolapse in 97 per cent oof cases. Of those patients who had been incontinent, satisfactory restoration of continence was achieved in 79 per cent of cases for solid faeces and in 33 per cent for fluid faeces. Ivalon sponge is a foreign material that only produces moderate fibrosis in the tissues. In persists foor at least 6 years in humans.
