Does antral localization worsen the efficacy of enteral stents in malignant digestive tumors?
The palliative treatment of malignant gastric outlet obstruction with a uncovered metal stent produces a significant improvement of oral food intake and maintains the overall quality of life index. The antral localization is associated with a lower efficacy of the procedure.
Our results revealed a significant decrease in the frequency of HBVMN in children with NS and in long-term follow-up HBsAg carriers. Children with HBVMN are primarily infected with HBV via horizontal transmission; thus, the significant reduction in horizontal transmission in HBsAg-carrier children in the general population after universal HBV vaccination may explain the reduction of HBVMN in the vaccinated population. These findings confirm the effectiveness of HBV vaccination on reducing the incidence of HBVMN, possibly through a significant decline in horizontal HBV infection.
