[Esophageal variceal band ligation in Dakar, Senegal].

After a preliminary study in the gastrointestinal endoscopy center of the Aristide-Le-Dantec Teaching Hospital in Dakar, Senegal, demonstrated the feasibility and effectiveness of endoscopic ligation of esophageal varices, this procedure entered regular use for management of patients admitted for upper digestive tract bleeding due to these varices. This study sought to assess its effectiveness. Patients and method. This study, conducted from July 2005 through January 2010, included all patients with upper digestive tract bleeding due to rupture of esophageal varices. Results. In all, 140 patients with a mean age of 36 years [range: 16-75] were admitted for this diagnosis and included in the study: 93 men and 47 women (sex-ratio = 1.98). The presence of at least one clinical sign of portal hypertension was noted in 72% of cases. Esophageal varices were graded as stage III in 75.7% of cases. The underlying cause of portal hypertension was cirrhosis in 94.3%, presumptively due to hepatitis B virus among 37.1%. The varices were successfully eradicated in 64 patients (45.7%). The mean number of sessions required was 2 [range: 2-4] in patients with stage II and 3.4 [range, 3-8] in patients with stage III varices, and the mean number of bands applied per session was 5.1 [range: 2-6] and 5.6 [range: 2-10], respectively. The interval between sessions was 4 weeks [range: 3 -12]. Bleeding recurred in 8 patients (5.7%) before eradication was achieved; 4 (2.8%) of them died. Conclusion. Esophageal variceal ligation is an effective therapeutic and prophylactic procedure for management of esophageal varices in Senegal.
