It is then more recommended to prolong first-line treatment. In order to be acceptable, the clinical efficacy of treatment must be higher than 90%. Aim: We aimed to assess the outcome of prolonged first-line treatment among adults.

Results: In the different medical centers for 19 months, 365 patients were compiled. The sex-ratio was 0.64. The average age was 43.55 years. The treatment efficacy was 92.88%. Treatment efficacy was better with p-value <10 -3 depending on prescriber: gastroenterologist (94.07%), general practitioner (75%); compliance before treatment: excellent (95.88%) or bad (50%); number of consultations: ≥four (94.35%), three (96.32%), two (78.85%). Triple therapies efficacy was 90.81%; p = 0.19. Quadritherapy efficacy was 95%; p = 0.5. Conclusion: This research is a contribution to the advent of national or African recommendations.
