Registry-based study shows surgical shunts prevent bleeding in patients with portal vein obstruction, suggesting effective long-term management.

To evaluate long-term outcomes of patients with extrahepatic portal vein obstruction and the impacts of surgical interventions.
Utilized a nationwide registry to track patient outcomes from 1987 to 2023.
Assessed the effectiveness of surgical shunts and mesoportal bypass on managing complications.
Analyzed associations between previous splenectomy, shunt function, and portal hypertensive biliopathy.
Surgical shunts effectively prevented variceal bleeding in the long term.
Mesoportal bypass significantly reduced the need for endoscopic interventions.
Previous splenectomy and lack of functioning shunt were linked to an increased risk of portal hypertensive biliopathy.

Luoto et al. (2026) studied this question.
