However, it presents challenges such as limited field of view and organ deformations. Surgeons rely on laparoscopic ultrasound (LUS) for guidance, but mentally correlating ultrasound images with pre-operative volumes can be difficult. In this direction, surgical navigation systems are being developed to assist with intra-operative understanding. One approach is performing intra-operative ultrasound 3D reconstructions. The accuracy of these reconstructions depends on tracking the LUS probe.Material and methods: This study evaluates the accuracy of LUS probe tracking and ultrasound 3D reconstruction using a hybrid tracking approach. The LUS probe is tracked from laparoscope images, while an optical tracker tracks the laparoscope. The accuracy of hybrid tracking is compared to full optical tracking using a dual-modality tool. Ultrasound 3D reconstruction accuracy is assessed on an abdominal phantom with CT transformed into the optical tracker's coordinate system.Results: Hybrid tracking achieves a tracking error < 2 mm within 10 cm between the laparoscope and the LUS probe. The ultrasound reconstruction accuracy is approximately 2 mm.Conclusion: Hybrid tracking shows promising results that can meet the required navigation accuracy for laparoscopic liver surgery.","PeriodicalId":18537,"journal":{"name":"Minimally Invasive Therapy & Allied Technologies","volume":" ","pages":"176-183"},"PeriodicalIF":1.7,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139707158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By constructing the testing equipment to physically measure the stent specimen, the experimental results reflect the trend of change and the simulation results are basically consistent, i.e. the mechanical properties of the thoracic aortic stent designed in this study is feasible and the measured data are valid.

To test the feasibility of robotic-assisted CT-guided punctures (RP) and compare them with manual laser-guided punctures (MP) with Uro Dyna-CT (Siemens Healthcare Solutions, Erlangen, Germany).Material and methods: The silicon kidney phantom contained target lesions of three sizes. RP were performed using a robotic assistance system (guidoo, BEC GmbH, Pfullingen, Germany) with a robotic arm (LBR med R800, KUKA AG, Augsburg, Germany) and a navigation software with a cone-beam-CT Artis zeego (Siemens Healthcare GmbH, Erlangen, Germany).

Besides, the novel structural design of the Plum electrode can counteract the tension generated by intestinal peristalsis and enhance the biomechanical strength of the anastomotic area.

With the ageing of the general population, treatment in elderly patients has become increasingly common; however, the gold standard treatment in this population remains unclear. The aim of this study was to evaluate the outcomes of laparoscopic Heller-Dor myotomy (LHM) in geriatric patients.Material and methods: In this study, consecutive achalasia patients undergoing LHM at the University Hospital 'Federico II' of Naples from November 2018 to November 2022 were prospectively enrolled. Patients were divided into two groups based on their age at intervention: elderly (≥70 years) and younger (<70 years). The two study groups were compared by minimizing the different distribution of covariates through a propensity score matching analysis (PSM).Results: In both populations, there was a significant improvement in terms of manometric parameters and symptoms after surgery. After applying one-on-one PSM, we obtained a total population of 48 achalasia patients divided into two groups (24 patients each). No significant differences were found in terms of demographic characteristics as well as preoperative and intraoperative variables between two groups.
