[Appendicectomy in the tropics: prospective study at Hôpital Principal in Dakar]

Acute appendicitis is the most common surgical indication in Africa. It is associated with higher mortality and morbidity than in industrialized countries. The purpose of this prospective 100 case study was to evaluate diagnostic, clinical and paraclinical features as well as surgical modalities especially with regard to approach and postoperative recovery in patients that underwent surgical treatment for appendicitic syndromes over a 9-month period at our institution. Analysis of study data confirmed that surgical indications could be established based on clinical examination alone and that adjuvant investigations only delayed therapy while providing little specific, useful information. Delayed management is a specific feature of tropical areas. Surgical exposure was achieved by the MacBurney approach in 65% of cases, celioscopic approach in 18%, and median laparotomy in 17%. The benefit of the celiosocopic approach was statistically signicant in terms of resumption of eating, duration of hospitalization and incidence of postoperative complications. Mortality in this series was 0% and morbidity was 7% mainly due to parietal complications.
