Abdominal surgery in patients with chronic extra-hepatic portal vein obstruction

Sep 9, 2020

This retrospective case-control study aims to evaluate the outcome after abdominal surgery in patients with non-cirrhotic chronic extra-hepatic portal vein obstruction (EHPVO), when compared to patients without EHPVO. Patients with known EHPVO who underwent abdominal surgery between 2000 and 2020 will be included, and compared with patients without EHPVO who had a similar surgical intervention. A special attention will be paid to portal-hypertension related complications, and bleeding complications.

Project recruiting


  • To retrospectively assess the outcome of adult patients with EHPVO who underwent abdominal surgery (except surgical portosystemic shunt).
  • To retrospectively assess the impact of portal decompression (either surgical portosystemic shunt or radiological shunt) before or at the time of surgery on postoperative outcome.
