Solitary rectal ulcer syndrome (SRUS) is an unusual disorder which is seldom seen in our hospital. Considerable uncertainly remains concerning the cause, natural history, and management of this condition. During 1980-1992 period, 7 patients were seen at the Instituto Nacional de la Nutrición and the diagnosis was established on histological, sigmoidoscopic and clinical grounds. Most of the patients suffered rectal bleeding, abdominal pain, straining at defecation, tenemus and rectal mucus discharge. Laboratory results were non specific. Eighty-five percent has macroscopic ulcerations and these were found within 5.2 cm of the anal margin and usually situated anteriorly. Neither medical nor local surgical treatment consistently achieved relief of symptoms or healing of the lesion.
