It is most often secondary to perforation of the digestive organ and/or the spread of an intra-abdominal septic focus. The absence of a study on peritonitis in a reference health center motivated us for this work. The aim of this study was to study the inadequacies that could be seen in the management of peritonitis in the CSRef(s). We carried out a retrospective study of 40 patients received at the CSRéf of commune I for acute generalized peritonitis from 2011 to 2012. The average age was 30.1 years with a standard deviation of 3.4;extremes ranging from 14 years to 60 years and a Sex ratio = 1.22 (22 men out of 18 women). Abdominal pain was the main reason for consultation (present in all our patients). In most cases, clinical examination alone made it possible to make the diagnosis. Surgical treatment depended on the etiology (appendectomy associated with washing-drainage was the most commonly performed surgical procedure). All our patients received general anesthesia. The average length of hospitalization was 7 days with extremes ranging from 1 to 15 days. We noted a Morbidity rate of 22.5%, dominated by wall abscesses and a mortality of 2.5%. The delay in consultation and referrals constitutes a factor in mortality and high morbidity.展开更多

The objectives of this work were to study acute peritonitis in the general surgery department of the Cs ref of commune I in Mali, to determine the frequency of peritonitis, to describe the epidemiological, clinical and therapeutic aspects in order to analyze the surgical consequences and to assess the additional cost of treating acute peritonitis. This study was prospective, descriptive, cross-sectional involving 40 patients received in the surgery department of the Cs ref of commune I for acute peritonitis from January 1, 2018 to December 31, 2018. There were 40 patients among whom 28 (70%) were men and 12 were women (30%), i.e. a sex ratio = 2.3. The average age was 25 years with extremes varying between 16 and 54 years and a standard deviation of 11.78. Abdominal pain was the main reason for consultation. Clinical examination alone made it possible to make the diagnosis in 75% of cases. Surgical treatment depended on the intraoperative etiology. The clinical diagnosis was supported by ASP and abdominal ultrasound;performed respectively in 10% and 90% of patients. Appendiceal peritonitis was the intraoperative diagnosis observed in 50% of cases. All our patients benefited from a peritoneal toilet with drainage. We noted a morbidity rate of 5% dominated by parietal suppuration. The average cost of care was 175,000 FCFA.展开更多
