Value of the surgeon's sightline on hologram registration and targeting in mixed reality.

Purpose: Mixed reality (MR) is being evaluated as a visual tool for surgical navigation. Current literature presents unclear results on intraoperative accuracy using the Microsoft HoloLens 1. This study aims to assess the impact of the surgeon's sightline in an inside-out marker-based MR navigation system for open surgery.

Semi-automated vs. manual 3D reconstruction of central mesenteric vascular models: the surgeon's verdict.

Background: 3D vascular anatomy roadmaps are currently being implemented for surgical planning and navigation. Quality of the reconstruction is critical. The aim of this article is to compare anatomical completeness of models produced by manual and semi-automatic segmentation.

Right Colectomy with Extended D3 Mesenterectomy: Anterior and Posterior to the Mesenteric Vessels.

Background: In right colectomy for cancer, complete mesocolic excision and D3 lymphadenectomy each leave behind lymphatic tissue anterior and posterior to the superior mesenteric vein (SMV) and artery (SMA). In this article, we present D3 extended mesenterectomy: a surgical technique that excises the lymphatic tissue en bloc with the right colectomy specimen.

Material And Methods: A 3D map of the mesentery of the right colon was reconstructed from staging CT-angiogram scans.

Post-discharge complications in frail older patients after surgery for colorectal cancer.

Background: The incidence of postoperative complications after colorectal cancer surgery varies between publications. Complications occurring after discharge from hospital are often not reported. The aims of this study were to investigate the proportion of frail older colorectal cancer patients who developed complications only after discharge, the severity of post-discharge complications, and the time point at which the most frequent complications occurred.
