A Comparative Study of an Integrated Ultrasonic/Bipolar Sealing Device Versus an Articulating Bipolar Sealing Device for Laparoscopic Liver Surgery.

Background: Sealing devices (SD) seal and cut tissue through different energy modalities, and are routinely used in laparoscopic liver surgery (LLS). The aim of this study is to compare the outcome of Thunderbeat (TB), an integrated ultrasonic/bipolar SD, versus Enseal (ES), an articulating bipolar SD, in LLS.

Methods: A retrospective analysis was conducted in a single center from December 2013 to September 2020.

The impact of type 1a endoleak on the long-term outcome after EVAR.

Objective: Endoleaks remains a major determinant of outcome after endovascular aortic repair (EVAR) for infrarenal abdominal aortic aneurysms. The objective of this study is to evaluate the long-term impact of proximal type 1 endoleak encountered at the case end of the EVAR procedure or during follow-up.

Methods: All patients treated with EVAR between February 2001 and August 2017 in our institution were included.
