BACKGROUND
Typhoid intestinal perforation is a surgical problem with severe morbidity and high mortality in North Central Nigeria.
METHODS
In order to determine the pattern and the prognostic indices, we studied 101 patients with typhoid intestinal perforation managed over a ten-year period
RESULTS
Children constituted 49% of the cases and majority (78%) of the patients were in the low socio-economic strata. The incidence peaked to 67% between November and March - the dry season in Nigeria. The male/female ratio was 1.9:1 with a mean age of 19 years and a mean hospitalization period of 18 days. There were 167 perforations; four involved the large bowel and appendix, and in 72.2% cases, the perforation was single. The mortality rate was 13.9%, affected mostly children and significantly worsened by prolonged perforation-surgery interval > 72 hours, jaundice, convulsion, ASA V, faecal peritonitis and re-exploration for early intra-peritoneal complications. Morbidity rate was 65.3% and significantly affected more children than adults and associated with perforation-surgery interval of between 24 and 72 hours, haematochezia and multiple perforations. Moribund patients fared better when operated upon under local anaesthesia with adequate analgesia. The least traumatic but effective surgical procedure that could seal the perforations and keep the peritoneum clean gave the best results. Children who survived up to 5 days and adults who survived up to 10 days after surgery had better chances of survival.
CONCLUSIONS
The most significant prognostic factor is late presentation which prolongs perforation-surgery interval and the other complication and mortality indices are directly influenced by it.
