Abstract A review of 110 cases of cecocecal intussusception is presented. The lesion constitutes 72 per cent of all intussusceptions reported from University College Hospital, Ibadan, Nigeria, and it is confined predominantly to the Yoruba tribe. Mean age of onset of the disease is ten years and the process presents clinically as a chronic, low grade small bowel obstruction associated with a palpable abdominal mass in the area of the colon. Resection for the obstructing lesion was necessary in only 10.9 per cent of cases and over-all mortality was 6.4 per cent even though more than 60 per cent of the patients had symptoms for more than six days duration. The pathogenesis of the process is discussed but the causes remain obscure.
