Complications des prises en charge chirurgicales des abdomens aigus non traumatiques d'origine digestive à l'hôpital central de Yaoundé, Cameroun (novembre 2019 - juillet 2020)

OBJECTIVE: Acute non-traumatic digestive surgical emergencies are a frequent cause of emergency in Africa. We undertook this study to investigate the morbidity and mortality of these patients in Cameroon, a developing country in Central Africa. PATIENTS AND METHODOLOGY: This was an analytical cross-sectional study with prospective data collection, over a period of eight months (November 2019 to July 2020), at the Yaoundé central hospital (Cameroon). The latter is a second category (intermediate) public health facility in the Cameroon health pyramid, mainly welcoming patients without health insurance. All patients operated on for an acute non-traumatic digestive abdomen were included. The patients were followed up until the 12(th) postoperative week. We used Cox univariate regression to determine factors associated with the occurrence of postoperative complications. The significance threshold retained was 0.05. RESULTS: We collected 120 patients, representing 14.6% of all surgical emergencies. The mean age of the patients was 37.6 ± 13.5 years. Eighty (66.7%) were male with a sex ratio of 2. The two main preoperative diagnoses were acute generalized peritonitis (n = 58 or 48.3%) and intestinal obstruction (n = 38 or 31.7%). The two main etiologies were peptic ulcer perforation (n = 35) and acute appendicitis (n = 24). The delay between the onset of symptoms and consultation was 1.9 day and an average of 36.8 hours elapsed between diagnosis and surgery. During postoperative time the morbidity and mortality rates were 33.3 and 10%, respectively. Postoperative complications were mostly minor according to the Clavien-Dindo classification, with 21 cases of grade I (33.8%) and 12 cases of grade II (19.3%). The main cause of death was sepsis (8 out of 12 cases). We identified seven factors significantly associated with an increased risk of postoperative complications among whom three were modifiable: The consultation delay greater than 72h (p = 0.02), the time between diagnosis and the surgical intervention greater than 48h (p = 0.01) and the operating time greater than 2h (p = 0.05). CONCLUSION: In our context, the results of the surgical management of acute non-traumatic abdomens of digestive origin are marked by high morbidity and mortality. The possible solutions are: the organization of public awareness campaigns to prompt rapid consultation in the event of acute abdominal pain, the establishment of universal health coverage as well as the improvement of technical platforms.
