Robotic sugarbaker parastomal hernia repair: updated series and outcomes.
Hernia
January 2025
Division of Gastrointestinal and Minimally Invasive Surgery, Department of Surgery, Carolinas Medical Center, 1025 Morehead Medical Drive Suite 300, Charlotte, NC, 28204, USA.
Purpose: To present updated outcomes after previously describing a novel technique for the robotic repair of parastomal hernias.
Methods: Patients who underwent parastomal hernia repair with a robotic Sugarbaker technique at a tertiary hernia center were identified from an institutional database. The approach involves mesh placement in the intraperitoneal or preperitoneal position after closure of the fascial defect.
Development of a New Score Based on Image Defined Risk Factors to Standardize Surgical Risk in Neuroblastoma Resection - A SIOPEN Collaborative Study.

Background And Aims: Image Defined Risk Factors (IDRFs) assess surgical risk in neuroblastoma (NB) and guide neoadjuvant therapy. Despite chemotherapy IDRFs may persist in 70 % of cases. Several studies have suggested that not all IDRFs hold equal significance and that the presence of an IDRF does not inherently signify unresectability.

Ischaemic heart disease remains a leading cause of premature mortality and morbidity. Understanding the associated pathophysiological mechanisms of cardiac dysfunction arising from ischaemic heart disease and the identification of sites for new therapeutic interventions requires a preclinical model that reproduces the key clinical characteristics of myocardial ischaemia, reperfusion and infarction. Here, we describe and validate a refined and minimally invasive translationally relevant approach to induce ischaemia, reperfusion and infarction in the sheep.

Intra-operative tensioning of the posterior cruciate ligament (PCL) in total knee arthroplasty (TKA) is commonly based on the surgeon's experience, resulting in a possibly loose or overly tight PCL. To date, the consequences of different PCL tensioning scenarios for the post-operative biomechanics of the knee remain unclear. Using a comprehensive musculoskeletal modelling approach that allows predictive joint kinematic and kinetic balance, we assessed variations in the movement and loading patterns of the knee as well as changes in ligament and muscle forces during walking in response to systematic variations in the PCL reference strain.

Local biaxial deformation plays a pivotal role in evaluating the tissue state of the ascending aorta and in driving intramural cell-mediated tissue remodeling. Unfortunately, the absence of anatomical markers on the ascending aorta presents challenges in capturing deformation. Utilizing our established intra-operative biaxial strain measurement method, we delineated local biaxial deformation characteristics in patients undergoing aortic valve replacement and coronary artery bypass graft surgery recipients (n = 20), and Aortic Repair surgery patients (n = 47).
