Adult intussusception: the Jos experience

Abstract

Twenty two consecutive cases of adult intussusception managed between January 1990 and December 1998 at Jos University Teaching Hospital formed the basis of this study. Thirteen (59.1%) of the patients were males and 9(40.9%) females, with a male to female ratio of 1:4:1 and a mean age of 49.6 years. Most patients were referred late to our service as a result of poor index of suspicion and misdiagnosis. Laparotomy was done in all the cases and in 5(22.7%) patients no cause could be found, but in the remaining 17(77.3%) definite causes were identified which were mainly polyps in 7(31.8%) patients and colonic malignancies in 4(18%). The ileocolic intussusception was the commonest variety. Sixteen (72.7%) patients had bowel resection for colonic carcinoma, gangrenous bowel and irreducibility of the intussusception while manual reduction was successful in the other 6(27.3%) patients. The morbidity rate was 22.7% and the complications were wound infection and adhesive intestinal obstruction. Two deaths were recorded with a mortality rate of 9.1%. The pattern of adult intussusception as seen in the western world was observed in this tropical highland.
