title: [Acute appendicitis at the National University Hospital in Bangui, Central African Republic: epidemiologic, clinical, paraclinical and therapeutic aspects].
abstract: We carried out a retrospective study to analyse clinical, paraclinical and therapeutic aspects of acute appendicitis cases as the National University Hospital (CNHU) at Bangui in the Central African Republic. We compared our findings with those for other African countries and for industrialized countries. From September 15 1990 to February 15 1992, 285 patients underwent laparotomy to treat acute appendicitis. We carried out a study of clinical, paraclinical and therapeutic aspects on 57 patients with complete case histories (20% of the patients undergoing surgery). The appendices of these patients were sent to the Laboratory of Pathological Anatomy of the Faculty of Medicine at Marseille, France, for analysis. The frequency of appendectomy among patients undergoing visceral surgery by laparotomy with no acute traumatic abdominal syndrome was 42.3%. The incidence of appendectomy for the city of Bangui in 1991 was 36.5 per 100,000 inhabitants. These cases of appendicitis were diagnosed essentially on clinical grounds. Leukocyte counts exceeded 10,000 per mm3 in 30% of the patients. Histological examination revealed the presence of parasites in 10 cases : Schistosoma mansoni eggs (seven cases) and Ascaris lumbricoides eggs (one case) in patients with acute appendicitis and one case each of Schistosoma mansoni eggs and Ascaris lumbricoides eggs at the time of diagnosis but normal histological results for the removed appendix. Most of the patients consulted late, a mean of four days after the onset of symptoms. The frequency of appendectomy on principle was 12.7% and parenteral antibiotic treatment was prescribed systematically follow- ing surgery. The mean duration of hospital stay after surgery was 7.6 days. No early postoperative complications were noted. However, two late postoperative complications resulting in the death of the patient were observed, giving a mortality rate of 3.5%. These complications were one case of peritonitis after appendectomy involving intestinal resection and one case of occlusive syndrome with septic shock. The frequency of acute appendicitis at the CNHU at Bangui was similar to that reported in another tropical African country (~ 1%). However, the incidence of appendectomies at Bangui is lower than generally reported for western countries (15 to 40%). Positive diagnosis was made on classic data obtained on clinical examination and on associated biological data, if available. Parasites were identified on histological examination in some cases of acute appendicitis, but it is unclear whether these parasites were actually responsible for the appendicitis. Efficient examinations for the exploration of acute nonspecific abdominal pain, such as the measurement of inflammation indicators, particularly serum activated protein C levels, graded-compression ultrasound scans and celioscopy, should be made available in the hospitals of African countries to increase the precision of diagnosis and to decrease the still too high frequency of appendectomies performed on principle. The postoperative mortality rate at the CNHU of Bangui is higher than the low rates (0.1 to 0.25%) reported for industrialized countries but is close to those reported for African countries. This high rate of mortality results partly from the lateness of consultations, because patients in tropical Africa often consult a traditional healer before resorting to modern medicine, and partly from misdiagnoses.
