[Clinical and endoscopic features of solitary rectal ulcer syndrom in the digestive endoscopy unit of Hospital Aristide Le Dantec in Dakar].

Introduction: The solitary rectal ulcer syndrome is a rare disease. In Africa only few studies have been held on this subject. The aim of this study was to determine the epidemiological, clinical and endoscopic aspects of this syndrome in the digestive endoscopy unit of hospital Aristide Le Dantec in Dakar.

Patients and method: It was a retrospective study based on all the cases of solitary rectal ulcer regarding to the conclusion of endoscopic examination from January 1994 to June 2002. All the patients without histological confirmation were excluded.

Results: We had recruited 11 cases among 4250 endoscopic exam (0.26 %). The mean age was 40 years (extreme 23 to 63 years). Female to male ratio was 1.75 with 4 males and 7 females patients. The main indications of endoscopic examination were frequently associated and were dominated by intermittent bleeding (8 cases) chronic constipation (6 cases) and false chronic diarrhea with muco hemorrhagic discharge (4 cases). The mean duration of the symptoms was 5 years. Ulcers were ovoid or circular. Their mean diameter was 8 mm and they were located 8 cm above the anal margin. The lesion was unique in 55 % of the cases and concerned the anterior wall of the rectum in 74% of the cases. There was an internal rectal prolapse in 54% of the cases.

Conclusion: The solitary rectal ulcer syndrome is not frequent in the endoscopy unit of hospital Aristide Le Dantec in Dakar. It affects mostly young adult female. The symptoms are chronic and non specific. In tropical areas the disease is frequently misdiagnosed as colic amoebiasis.
