Etiological, therapeutic and prognostic particularities of primary biliary peritonitis in tropical environments.

To describe the etiological, therapeutic, and prognostic aspects of primary biliary peritonitis in Burkina Faso. This retrospective study reviewed records of all patients admitted for primary biliary peritonitis at Tenkodogo Regional Hospital (Burkina Faso) from 2010 through 2016. Cases of secondary biliary peritonitis have been excluded. Thirty patients were identified. Their average age was 26.5 years. Fourteen patients were under 12 years of age. The reasons for consultation were dominated by abdominal pain (in all cases) and bile-induced vomiting (in 22 cases). Seven patients had a general condition classified in stage 2 of the World Health Organization classification, 18 in stage 3, and 5 in stage 4. The etiologies of peritonitis were acute typhoidal cholecystitis, which predominated (27 cases), and gallstones (3 cases). The surgical approach was a laparotomy in all cases. Intraoperative observation showed an inflamed and perforated gallbladder in 24 cases; gangrene was noted in 6 cases. Treatment consisted of cholecystectomy and peritoneal lavage, associated with antibiotic therapy. The post-operative period was complicated by septicemia in 12 cases. Fourteen patients died, for a mortality rate of 46.7 %. In rural Burkina Faso, primary biliary peritonitis occurs in young subjects. Its cause is most often acute cholecystitis due to Salmonella typhi. Mortality is very high.
