Aim : To contribute to the study of peritonitis by ileal perforation in the department. Material and Methods : This was a retrospective, descriptive study over five years from 1 January 2016 to 31 December 2020. Results : We collected 30 cases of ileal perforation peritonitis (6.7%). The mean age of our patients was 26.06 years and the extremes were 8 and 78 years. The sex ratio was 3.28. Students were the most represented socioprofessional group (43.33%) and 80% of patients came from the city of Conakry. Abdominal pain, parietal defence and painful rectal touch were present in all our patients (100%). Declive dullness and disappearance of prehepatic dullness represented respectively 80 and 66.66%. General condition was poor in 56.66% and impaired in 20%. Typhoid perforation was the most frequent etiology in 40% of cases and perforation was unique in 26.67% of cases. Suture excision was the most common procedure. The postoperative course was favourable in 40% of cases, with complications in 53.33% and death in 43.33%. The average hospital stay was 14.6 days with extremes of 1 and 49 days. Conclusion : Peritonitis due to ileal perforation is relatively frequent in the department and very serious. The diagnosis is essentially clinical and typhoid fever is the main etiology. Early diagnosis, availability of the emergency kit and equipment of the resuscitation department could improve the prognosis.
