Institut Mutualiste Montsouris classification is associated with postoperative portal vein thrombosis in laparoscopic liver resection.

Background: Laparoscopic liver resection (LLR) is a surgical procedure with varying degrees of difficulty depending on tumor status and surgical technique. Therefore, we aimed to evaluate the relationship between surgical difficulty levels and outcomes of LLR, particularly portal vein thrombosis (PVT).

Methods: We performed LLRs in 214 patients between January 2009 and December 2022.

Photooxidation Cross-Linked, Glutaraldehyde Cross-Linked, or Enzyme and Hydrostatic Pressure Processed Decellularized Biomaterials for Cardiovascular Repair Do Not Affect Host Response in a Rat Right Ventricular Outflow Flow Tract Reconstruction (RVOT) Model.

Cardiovascular diseases (CVDs) were responsible for approximately 19 million deaths in 2020, marking an increase of 18.7% since 2010. Biological decellularized patches are common therapeutic solutions for CVD such as cardiac and valve defects.

Effect of a Training System Utilizing 3D-Printed Patient-Specific Vascular Models on Endovascular Catheterization Performance.

This study aimed to examine the effect of simulation training using a three-dimensional (3D)-printed patient-specific vascular model on the advanced vascular catheterization skills of experienced interventional radiologists (IRs). Two specific anatomic types of 3D-printed patient-specific models from two patients with challenging celiac axis arterial anatomy were constructed. The Global Rating Scale of Endovascular Performance (GRS-EP) was used to evaluate vascular insertion skills.

Intraoperative tumor capsule injury in patients with renal cell carcinoma receiving partial nephrectomy.

Objective: We investigated the impact of intraoperative tumor capsule injury (TCI) during robot-assisted partial nephrectomy (RAPN) or laparoscopic partial nephrectomy (LPN) on oncological outcomes, as well as underlying factors of intraoperative TCI for improving surgical outcomes.

Methods: A total of 253 patients who underwent RAPN or LPN between 2010 and 2022 were retrospectively analyzed and were divided into two groups: non-TCI and TCI groups. The background was compared between two groups.
