Prognostic factors in typhoid perforation.

A review of 60 patients undergoing surgery of typhoid perforation at the Ahmadu Bello University Teaching Hospital in Northern Nigeria between January 1981 and April 1987 was performed. Solitary perforation of the terminal ileum was found in 45 of 58 (78%) patients. 52 (87%) patients had debridement of the edge of perforation and simple closure. The overall hospital mortality was 57%. Important prognostic factors identified were blood urea level and duration of perforation before admission. In order to improve prognosis in typhoid perforation, patients must present early to hospital where early diagnosis, aggressive resuscitation and prompt surgery should be carried out.
