“…Neben bildgeführten Systemen verspricht außerdem die Möglichkeit der Lokalisierung und Überwachung von chirurgischen Werkzeugen im intraoperativen Umfeld, die chirurgische Präzision und Sicherheit zu verbessern. Durch den Einsatz von mechanischen, optischen und elektromagnetischen Ortungssystemen sollen Chirurgen bei endoskopischen und laparoskopischen Eingriffen eine verbesserte Navigation und Kontrolle über ihre Instrumente erreichen [42,43,44]. Diese Ortungssysteme zielen darauf ab, genaue Positionsdaten bereitzustellen, die oft mit präoperativen Bildern und intraoperativen Aktualisierungen kombiniert werden, um ein umfassendes virtuelles Modell zu erstellen.…”

ZusammenfassungDie chirurgische Navigation, auch als computerunterstützte oder bildgeführte Chirurgie bezeichnet, ist eine Technik, die eine Vielzahl von Methoden wie 3-D-Bildgebung, Tracking-Systeme, spezialisierte Software und Robotik einsetzt oder als Plattform nutzt, um Chirurgen während chirurgischen Eingriffen zu unterstützen. Diese neuen Technologien zielen darauf ab, nicht nur die Genauigkeit und Präzision chirurgischer Eingriffe zu erhöhen, sondern auch weniger invasive Ansätze zu ermöglichen, mit dem Ziel, Komplikationen zu reduzieren und die operativen Ergebnisse für Patienten zu verbessern. Durch die Integration aufkommender digitaler Technologien verspricht die chirurgische Navigation komplexe Eingriffe in verschiedenen medizinischen Disziplinen zu unterstützen. In den letzten Jahren hat das Gebiet der chirurgischen Navigation bedeutende Fortschritte gemacht. Die abdominelle chirurgische Navigation, insbesondere Endoskopie und laparoskopische sowie robotergestützte Chirurgie, durchläuft derzeit eine Phase rascher Entwicklung. Schwerpunkte sind bildgestützte Navigation, Instrumentenverfolgung sowie die mögliche Integration von erweiterter und gemischter Realität (Augmented Reality, AR; Mixed Reality, MR). Dieser Artikel wird sich eingehend mit den neuesten Entwicklungen in der chirurgischen Navigation befassen, von modernsten intraoperativen Technologien wie hyperspektraler und fluoreszierender Bildgebung bis hin zur Integration präoperativer radiologischer Bildgebung im intraoperativen Setting.

“…One of them includes reconstructing a medical image such as computed tomography (CT) or MRI in 3D. This method is widely used for volume measurement and surgical planning related to cancer treatment 29–31 . In addition, several recent studies have shown that such a procedure is also useful in the evaluation of the heart, meniscus, and paraurethral mass, as well as spaces such as the cerebral ventricle and joint cavity 32–36 .…”

OBJECTIVE To establish a preoperative evaluation procedure by measuring the volume of dead space using MRI in patients with ischial pressure injuries. METHODS Patients with spinal cord injury and ischial pressure injuries who underwent treatment between August 2016 and November 2019 were included in the study. Preoperative MRI scan was conducted on all patients. The volume estimation and three-dimensional (3D) reconstruction were performed based on MRI data using a 3D Slicer. Based on the resulting volume, a muscle flap that could fit the dead space was selected. Surgery was performed with the selected muscle flap, and a fasciocutaneous flap was added, if necessary. RESULTS A total of eight patients with ischial pressure injuries were included in the study. The mean patient age was 59.0 ± 11.0 years. The mean body mass index was 26.62 ± 3.89 kg/m2. The mean volume of dead space was 104.75 ± 81.05 cm3. The gracilis muscle was the most selected muscle flap and was used in four patients. In five of eight cases, a fasciocutaneous flap was used as well. The mean follow-up period was 16 months, and by that point, none of the patients evinced complications that required surgery. CONCLUSIONS To the authors’ knowledge, this is the first report on volumetric evaluation of dead space in ischial pressure injuries. The authors believe that the 3D reconstruction process would enable adequate dead space obliteration in ischial pressure injuries. The authors propose that preoperative MRI scans in patients with ischial pressure injury should become an essential part of the process.

“…To perform volumetric analyses, MRI images were analyzed in three-dimensional (3D) Slicer (version 4.11), which is an imaging software previously used for RT planning for cancer treatment (24) and surgical planning (25). In the axial plane, VS borders were delineated and then volumes were calculated using Segment Statistics, a 3D Slicer module (Fig.…”

Objective:Vestibular schwannomas (VS) commonly undergo magnetic resonance imaging (MRI) surveillance, but long-term data to support the ideal frequency is limited. Herein, we aim to investigate intracanalicular VS growth predictors and long-term growth rates (GR).Study Design:Retrospective chart review.Setting:Two tertiary care centers.Patients:Sporadic intracanalicular VS with initial conservative management and at least two sequential MRIs.Intervention:Serial MRI.Main Outcome Measure(s):VS were categorized by baseline internal auditory canal tertile sublocalization (fundus, midpoint, porus) and size (≤100, 100–200, >200 mm3). Throughout follow-up, volumetric GR (mm3/yr) were determined (baseline–3 yrs, 3–5 yrs, 5–10 yrs) and treatment rates were assessed.Results:Ninety-nine intracanalicular VS were identified (mean follow-up of 6.1 ± 4.5 yrs). Mean GR before 5-year follow-up were comparable for baseline tertile involvement and size. After 5-year follow-up, mean GR of VS involving the fundus at baseline were lower than those involving the midpoint and fundus (6.17 ± 21.16 and 119.74 ± 117.57 mm3/yr, respectively; p = 0.034). Mean GR of VS with less than or equal to 100 mm3 at baseline (–7.29 ± 25.44 mm3/yr) were lower than those with 100 to 200 mm3 (86.55 ± 103.99 mm3/yr; p = 0.011) and more than 200 mm3 (45.70 ± 35.71 mm3/yr; p = 0.031). Vestibular schwannomas involving the midpoint and fundus had greater treatment rates compared with VS involving only the fundus (p < 0.001).Conclusions:Baseline tertile involvement and size may predict long-term intracanalicular VS growth where fundal tumors or those less than or equal to 100 mm3 exhibit little long-term growth. Extending surveillance after 5-year follow-up may be reasonable for fundal VS.
