[Sleeve gastrectomy for the surgical management of obesity at the Essos Hospital Center (Yaoundé, Cameroon): a retrospective case series study evaluating medium-term weight loss].

While the prevalence of overweight and obesity is rising in Africa, the practice of bariatric surgery remains limited in our country, Cameroon. Weight loss outcomes following sleeve gastrectomy (SG), the most widely used bariatric surgery technique worldwide, have not yet been studied in our context. The medical records of all patients who underwent SG in our surgery department between January 1, 2016, and September 30, 2020, were reviewed retrospectively. The primary outcome studied was medium-term weight loss, one year after surgery. Weight loss was calculated using the postoperative body mass index (BMI) and the percentage of excess weight loss (%EWL). Reinhold criteria were used to assess the %EWL. We collected data from the medical records of 21 patients, of whom 19 (90.5%) were female. The average age of patients was 40.3±10.8 years, with a mean BMI of 44.9±7.4 kg/m. All patients had at least one obesity-related comorbidity. All procedures were performed laparoscopically, without conversion, with a mean duration of 192.2±52.8 min. One year after surgery, the mean BMI was 32.51±3.7 kg/m and the mean %EWL was 63.35±6.5%. According to Reinhold's criteria, the %EWL was considered satisfactory. In our context, SG provides satisfactory results for medium-term weight loss.
